Since May, the "Guangdong Province to promote the use of LED lighting products implementation plan" has been issued, has touched the nerves of many people in the industry. When the documents are issued, they are equal to dropping the rice from the pot. Even if it is not yet finished, this “cooking†is an imperative situation. It can be seen that the government’s determination is bold and the action is vigorous and resolute. The government can have such a big move, naturally because of the confidence in the quality and prospects of LED lighting products. However, whether LED lighting has enough capacity to take on this “great responsibility†has been repeatedly questioned.
Positive point of view: Guangdong dares to "eat crabs" not to look at the policy significance
The introduction of a policy is not a reason for its existence. The world is not perfect. It does exist, and it may be regrettable. The official needs to correct its attitude and use a rational heart and calm mind to see the necessity of its existence. And advantages. In the voice of opposition, there are also industry experts who believe that LED lighting has achieved or exceeded 50% in the LED demonstration projects already implemented.
Regardless of any city, road lighting systems, nightscape landscape lighting systems and other important infrastructure are indispensable. The city lighting system brings convenience to people's lives while also consuming large amounts of electric energy. Urbanization brings greater demand for lighting and brings greater pressure. Energy-saving, low-carbon, green lighting, sustainable lighting... all are the direction that the development of lighting industry is looking for today.
On May 23 this year, the People's Government of Guangdong Province issued the "Guangdong Province's Implementation Plan for the Promotion of the Use of LED Lighting Products" (hereinafter referred to as the "Project") to implement a comprehensive strategic plan for the promotion of energy-saving and emission reduction, and the promotion of LED lighting and related industries. According to the plan implementation plan, Guangdong Province will popularize LED lighting in the public lighting field within three years. It is estimated that by the end of the “Twelfth Five-Year Planâ€, the LED industry can achieve an annual output value of more than 500 billion yuan.
Bring Green Lighting Ideas to Action
LED lighting as a green lighting, its energy conservation is no doubt, but also one of the general direction of the development of the lighting industry, is the common dream of the industry. The introduction of this policy is undoubtedly the gospel of the LED industry, bringing hope to the thirsty industries. Since the announcement of the plan, Dongguan, Shenzhen, Taishan, Shantou, Zhongshan, and even Guangdong, the east, west and west have successively introduced plans to vigorously promote LED lighting.
In an interview with the reporter, Tang Guoqing, general manager of CREE China Market, said that this policy is a double-edged sword. Under the premise of promoting energy conservation and emission reduction and the “Twelfth Five-Year Plan†on promoting green lighting, there is no doubt that Guangdong As an LED industry base, this move is in line with the country's guidelines and policies, and has set an example. Undoubtedly, the entire LED industry in China, especially the enterprise, is a big boost and an invigorator. “Guangdong Province is the province that has taken the lead in implementing this policy. It dares to innovate, dares to lead, and dares to create opportunities to promote the development of LED lighting. The Guangdong government is far-sighted. I think this idea and this approach are very innovative,†he said.
Data confirms significant LED energy savings
Guangdong is the first to take the crab as the "first person to eat crabs," which naturally caused a variety of sounds in the industry to set off waves. For this New Deal, the voice of opposition is even more prominent. The reason is that the current development of LED lighting technology is not enough to inherit the worry of "general reunification" of public lighting. In spite of this, relevant experts from the Guangdong Science and Technology Department stated that the prejudice regarding LED lighting is untenable, and they have used the data to argue that the energy-saving rate of LED demonstration projects that have already been implemented has reached or exceeded 50%.
In the New Deal program issued in Guangdong, it is shown that by promoting the implementation of applied projects, it will achieve lighting energy savings of more than 50% compared with the same caliber. According to media reports, in the renovation project in Chancheng District of Foshan City, more than 11,000 new high-power LED lamps were installed, saving more than 10 million kilowatt-hours of electricity per year compared to high-pressure sodium lamps, saving electricity rates of 62%, and saving more than 890,000 yuan in electricity bills. It is equivalent to saving 3,915 tons of standard coal, reducing 10,257 tons of carbon dioxide and 117 tons of sulfur dioxide, equivalent to an additional 598 acres of forest annually.
In addition, in Shenzhen Expressway LED street lighting and tunnel lighting project, the same tunnel lighting project was selected to compare the project cost of high-pressure sodium lamps and LED tunnel lights. The results show that if high-pressure sodium lamps are used, each kilometer tunnel requires 100 kwh of high-pressure sodium lamps of 530 ç›, the total investment of the lamps is 769,000 yuan, and the distribution line investment is 167,000 yuan, with a total investment of 936,000 yuan; but if LED lamps are used, the satisfaction is satisfied. Under the premise of the same lighting standard, only 286 LED tunnel lights are needed. The total investment in lamps is reduced by 44% compared with the use of high-pressure sodium lamps, and the investment in distribution lines is reduced by 50%. In addition, plus the LED operating life savings during the period of 101.7 million yuan, lighting maintenance spending 212,000 yuan, the entire new lighting projects from the investment to the latter part of the operating expenses, the same time saving 1.742 million high-pressure sodium lamp.
Promotes LED lighting with a wide range of applications
Energy-saving LED lighting is well-known, but most of the current use of outdoor lighting in the public domain, indoor lighting, especially home lighting can not be popular, so this market can currently be said that the potential shares, how can the LED light source into the ordinary people Home is a headache for countless businesses. According to a report released by the relevant departments of Guangdong Province in the past, LED companies in the United States, Japan, and Europe have more than 80% of LED chip core technology patents, and domestic similar companies have less than 10% of the same patents. For a long time, the core basic technology of epitaxial wafers and chips in the upstream of LED industry has been monopolized by several large industrial giants, occupying about 70% of the entire industry chain. This has also made the structure of China's LED industry chain very unreasonable, and the pressure has fallen heavily on LED. On the shoulders of the business.
The data show that as of the end of 2011, Guangdong Province, LED lighting demonstration project has promoted the use of LED street lamps 250,000 baht, pulling the LED lighting industry's annual output value reached 151.5 billion yuan, ranking first in the country. The government directly supports the LED lighting industry with “hands and feet†by “handsâ€. By popularizing the application of public lighting, it further promotes the extensive application of LED lighting in indoor and other fields.
Can use the EMC model or draw on the "US approach"
There is a foreign saying: "Any coin has two sides." It is true that everything exists in both positive and negative terms. The fact that the introduction of the Guangdong New Deal caused public opinion disturbance tells us that this policy is not absolutely perfect. It brings hope to the industry and also gives the industry more room to think and discuss.
The EMC model is no stranger to the LED lighting industry. It is a market-oriented energy-saving mechanism that can reduce the cost of energy-saving projects by reducing energy costs. Zhao Shengxin, the chief designer of Shenzhen Shangzhu Art Design Co., Ltd., also advocates the use of the EMC model. He said: "The contracted energy management (EMC) operating model should be a good mode of operation, but it should be more pragmatic to improve the operation of the market. In the implementation process, we should be able to achieve transparency and fairness at the source of policy implementation, and prevent power rent-seeking and engineering fraud.In terms of assessment, we should both measure energy efficiency indicators and measure economic efficiency, and we must pay attention to long-term assessment. You can't just look at the energy savings of the data, the effect of a year, but also pay attention to the effects of years later."
Anti-side point of view: large-scale application of artificial ripening LED "has not arrived yet"
Previously, regardless of the country's policy to promote the tilt, or the market itself, the heat has laid the LED lighting this "grandchildren" status. Including China’s ban on incandescent bulbs in October, it is almost an attempt to pave the way for LED to replace its market share. From time to time, to do the lighting of the open talk about LED, as if not just a night before returning to liberation so simple, but do not know to fall back to "Middle Age" which dark shadow. However, no matter who is in the industry or outside, there are not many people who really understand LED, and overwhelming people are gaining ground and tending to add strength. It also makes the prosperity of the LED lighting market a layer of fog and piles of bubbles.
Can the road lighting LED light activate the "cheese" of the high pressure sodium lamp?
The opinion of the unit struggling with a line lamp might be more persuasive. Zhang Tao, from the Lianyungang City Lighting Management Office in Jiangsu Province, once fought over the high-pressure sodium lamp: “The high-pressure sodium lamp itself is also a kind of green light source, and it is more mature. In cities, the high-pressure sodium lamps used in Osram and GE, under normal circumstances 250W sodium lamps, are absolutely no problem in five years, and the standard interfaces are the same.As a fourth-generation light source, LED is just one of them, the electrodeless lamp If the technical bottleneck breaks, it will not be worse than the LED."
High-pressure sodium lamps and LED lamps belong to lamps of two different light sources, because their light emitting principles are quite different, and the resulting lighting effects are completely different. Both have their own advantages, but compared with the development of relatively mature high-pressure sodium lamps, LED lamps still need to be breakthrough and development.
Wang Xiaoming of the Ministry of Construction of Shanghai stated: From the use aspect, the sodium lamp is still the biggest rival of the LED street lamp. There are manufacturers in the publicity efforts to exaggerate the energy-saving effect of LED street lamps, in the direction of which is open to question. If the sodium lamp technology is used as a reference system to examine LED street lamps, the difference in product prices can be offset by energy saving. The result can be imagined, after all, the sodium lamp's price/performance ratio is still very high.
According to Liu Wei, sales manager of Hella Industrial China, Guangdong is a pilot project, but it is a demonstration, but it is still not mature enough to use it on a large scale. Guangdong LED manufacturers are many, have formed a scale, but things are not really good, but also need to really work hard to do; now the LED lights compared with the traditional high-pressure sodium lamp, whether to meet the standard, there is no obvious advantage to Give a question mark.
Xie Junyan, director of the Shanghai Street Light Management Center, also raised objections. In his view, the application of LED luminaires at least on the expressway is not appropriate. Because of the penetrability of the LED, lighting is ineffective in fog, affecting traffic safety. He said: "At present, the use of high-speed LED applications is still too advanced. I once had discussions with industry experts on related issues. I mentioned many advantages of using LED lamps for highways, but in my opinion, the shortcomings are also obvious. "It's also fatal." He felt that LED lights could be applied to express roads and urban roads, but "if blindly applied on the highway, it would be inappropriate to discredit the LED lamps."
Xia Jun, the manager of the Shenzhen Light Tube Management Center, put forward diametrically opposed opinions. He said that extreme weather is a rare exception and sodium lights are not necessarily advantageous in extreme weather. "Under normal conditions, we can meet the needs, then there is no problem." In this regard, some people in the industry have stated that although experts have different opinions, the application of high-speed LED lamps and lanterns, driving safety requirements is very strict, and should always be the primary consideration.
Technical issues: Will the push of LED streetlights lead to "catastrophe"?
For the Guangdong Province to promote the practice of LED street lamps, the industry has been questioned before. In August, a company named Ruisenike Lighting System Technology Co., Ltd. issued an open letter to the Guangdong provincial government, which caused a heated debate.
The letter title is "Guangdong will change all street lights to LED street lights will be a disaster!"
The open letter believes that a good street lighting solution must consider five points. The first is the so-called "energy saving." The letter revealed that energy conservation is equivalent to the average power consumption of the average illumination, and the average illumination cannot be only the average illumination of the ground. The light intensity of the space has good predictability for vehicles arriving from afar and prevents traffic accidents from happening. Currently, LED street light manufacturers installed are difficult to achieve, and energy is saved at the expense of illuminance. Sodium lamps currently between 100-200 Lm/W are already a very efficient light source, and this LED has no advantage.
The second is that the outdoor ambient temperature is uncontrollable. The street lamp must be waterproof and dustproof. The lamp must be sealed. The temperature of the water vapor inside the lamp after sealing is more than 100 degrees under extreme weather conditions. The LED continuously works in a high-temperature environment, according to the current LED. The thermostat feature, even if you do the lamp is no better, will inevitably die or light fade. Thirdly, no light source has so far been better than sodium lamps. Fourth, the street lamp is stained with insects in the field and will seriously affect the light efficiency. The spectral characteristics of the sodium lamp avoid this phenomenon, while the LED cannot be avoided. Fifth, we must consider earthquake protection and typhoon prevention. At present, many street lamp replacement projects simply replace the traditional street lamp bases with LED lamp bases. This is very dangerous. The weight and frontal area of ​​the street lamp base must be carefully calculated, and whether the original lamp pole and foundation anti-seismic and anti-typhoon levels are in line with the local conditions.
This open letter, popular in the industry, analyzes the feasibility of LED lamps replacing sodium lamps in the field of public street lighting from the technical level. It is concluded that "LED is a new type of high-efficiency light source and currently has an irreplaceable advantage in replacing incandescent lamps and fluorescent lamps, but there is no advantage other than sodium lamp in replacing sodium lamps". He also pointed out that "if there are full replacement (especially main road) lights, traffic accidents will be significantly improved" and "real-day weather problems will cause large batches of dead lights or severe light failure" and other practical problems.
Zhao Shengxin, chief designer of Shangzhu Lighting, said that he had previously seen reports that if a high-pressure sodium lamp was used in an LED street light and tunnel light lighting project, a 100 kilowatt-hour high-pressure sodium lamp would be required to produce 530 turns per kilometer of tunnel, but if LED lights were used Only 286 LED tunnel lights are required to meet the same lighting standards. Zhao Shengxin bluntly expressed his skepticism about this. “According to my current experience, I feel that this is simply not possible. Now that LED lamps replace two 100-kilowatt-hour high-pressure sodium, it is impossible to satisfy the current LED lamps. Even LED lighting Lumen can reach or even surpass traditional light sources, but the brightness cannot be achieved.In practical applications, the number of LED lamps will exceed the number of traditional lamps more often.So we should have a comprehensive understanding of the energy-saving effect, can not be alone The power factor of one LED lamp is compared with the power of a high pressure gas discharge lamp. Energy saving effect I think we should consider the cost-effectiveness of energy saving, which is more practical and meaningful."
Chen Qiang, general manager of Jiangsu Skyline Lighting Engineering Co., Ltd. first affirmed that by stimulating the LED lighting industry in Guangdong and radiating to the whole country, it has a positive impact on the development of the industry. But at the same time, he also stated that “If large-scale promotion in Jiangsu is not suitable, and the provincial government has no plans and policies to implement, only experimental non-main street LED street lighting, the effect of feedback can be, but light The problem of failure still exists."
According to Ni Xinda, general manager of Prosper Electric (China) Co., Ltd.: From a technical point of view, LED lighting is not yet able to replace traditional lighting, and the cost is already several times that of traditional lighting. LED lighting does have the advantages of environmental protection and power saving. He reminded: "Do not go blindly to promote energy conservation, or even show, unless the LED lighting product technology, quality and other aspects of all through." He said Pross will not do high-power LED lighting products, including mining Lamps, street lights, and mainly to do low-power LED lighting products, such as landscape lighting. Because the high-power LED lighting itself has many problems, such as heat, heat dissipation, and poor light attenuation.
When Zheng Gang, the deputy general manager of Fuzhou Tonglian Installation Engineering Co., Ltd., accepted an interview with Aladdin Lighting News, he frankly stated that it is unreasonable to say that "LED lighting" is equivalent to "energy saving." On the contrary, using the minimum power to achieve the best light efficiency is energy saving. And not all places can use LED lighting, specific analysis of specific issues. He believes that the current road lighting sodium lamp can achieve the effect of energy saving, there is no need to carry out large-scale transformation. “There are still many problems in the market such as short life span, power damage, and lack of compliance in the market. In Fujian, LED lighting is rarely used on roads because of the problems of LED lighting itself. It's useful, but it's generally not effective, so the government must be cautious about popularizing LED lighting, and it must be realized that LED lighting does not completely replace traditional lighting."
Shanghai Aite Lighting Design Co., Ltd. general manager and director of lighting design Wang Jianping cited the LED lights still have many problems, including: 1. Sacrifice illumination. The decrease of the brightness level must be accompanied by a decrease in power; 2. The heat dissipation cannot be completely resolved, resulting in the light attenuation of the lamp; 3. The high-power LED lacks a reasonable light distribution design and glare control, and the strong light will make people feel dazzling and affect the comfort of the driver. .
Wang Jianping believes that the popularity of home lighting and commercial lighting is fast, LED replacement of high-energy spotlights, halogen lamps is more reasonable, cost-effective, energy-saving advantages are more obvious. The public lighting itself is a large-scale and large-area lighting. Nowadays, gold halide lamps used in functional street lamps have a greater advantage in terms of efficiency and longevity, and LED replacement will not be rapid.
He pointed out: "Before the government's application of LED industry is well understood, it is necessary to handle the popularization of LED street lights."
Time and scope issues: How can a fruit orchard not ripen to ripen an orchard?
In addition to the maturity of the LED technology, the timing of the “revision of Guangdong public lighting within three years according to the plan†was also questioned. Recalling that the “plan†was issued for more than three or four months, the performance of many cities in Guangdong province was not daunting, and people were not willing to set a timetable for completing the task. However, the LED application itself has a broad prospect and is not optimistic about the contradiction between the current, LED as a new generation of green light source, the government should make efforts to promote the application is understandable, but "strong twist can not be out of melon," the truth is also warning us, The promotion of subjective intention and the objective and practical popularization are often implemented in two different ways. The so-called "days to rain, mothers to marry", it should at least be "free love," rather than "arranged marriage." To truly achieve the significance of popularization, it is to let the market gradually accept the LED, and non-artificially hard-selling LEDs to the market and the public with a "time-limited subscription" model.
Guo Wenjun, director of the Urban Planning Institute of the Urban Planning Institute of China’s Urban Planning Institute and chief engineer of the Lighting Planning Department, said in an interview with Aladdin Lighting News: “Once we are based on the premise of doing a good job, we have a wide range of popularization and market feedback time. It may be in a year or so. If there are problems, especially security problems, and who will not be responsible for the responsibility of the problem first, but the head is not well prepared, what will be the follow-up situation? These are predictable futures. Administrative promotion of LED is an inevitable trend and means, but the meal is a bite to eat, do step by step, do not talk about the status quo industry confusion, product uneven, too many manufacturers, do not be distracted by the discourse can be confused. The project leader we implement and promote must have a clear understanding of the lighting market and development."
Yang Xiaoping of Beijing Electric Light Source Research Institute emphasized the quality and reliability of LED lamps in the interview. He believes that if the current LED can completely replace the sodium lamp, if the quality and reliability of the product can be guaranteed, then there is no problem. However, it is still not a one-size-fits-all approach to compulsory promotion. You can “first go from a small highway to a main road and then to a highway.â€
In this regard, Chen Yansheng, chairman of the China Lighting Association and Zhang Tao of the Lianyungang City Lighting Management Office in Jiangsu Province, said at the same time that high-speed LED street lights can be piloted, but it is not suitable for large-scale promotion. Technology and cost are the bottleneck of promotion. For the application scope of LED street lights currently in the expressway, Zhang Tao added: “The appropriate range of LED street lights for highway applications is 100 meters on both sides of the toll station, but all highways use LEDs to retain their opinions.â€
"The current LED technology is constantly developing, and many technical bottlenecks are continuously resolved, but before the overall and normative measures are solved, pilot applications can be applied. It is better not to use large-scale applications in functional lighting." Zhang Tao The views are quite representative of the industry's view of high-speed LED applications.
Tian Yanghua, Director of Natural Opto-electronics Market Division, also believes that with the current overall status of LED lighting, large-scale promotion is still not coming. He is worried: “(This is) excessive overdraft for the market, LED is used normally or immature, the government Using this method to release this demand is actually not conducive to the maturity of LED technology."
Ren Yuanhui, honorary director of the China Illuminating Society's Indoor Lighting Professional Committee, did not advocate this promotion. In an interview with Aladdin Lighting News, he told reporters bluntly: “Government agencies should not impose technical requirements in a few years. It is unwise to popularize public lighting.†He felt that it should be based on economic and technological comparisons to formulate specific technical standards, such as the use of what is reasonable. “At present, LED lighting itself does not have the conditions of use, such as color deviation, glare control, and price, although its prospects are very broad. For example, the use of three-color straight-tube fluorescent lamps in the office is sufficient, first of all, the price is reasonable, and then the effect is good. From the consumer From a point of view, there is no need to discard products that are cheap and expensive and choose products that are expensive and technically immature."
In an interview, Yu Anqi, chairman of the Shanghai Illuminating Society, said that in the case that the technology is still immature, large-scale application will cause waste of a lot of resources. He affirmed the bright future of LED light sources, and believes that the future will occupy a larger and larger share. However, he asserted to the reporter: "Even after another 5 years, LED will not be a situation that dominates the world, because some occasions are LEDs. Can't replace it."
Wu Hong, general secretary of China Light and Functional Materials Branch of China Rare Earth Industry Association, also believes that the promotion of LED lighting requires a process. “The overall idea of ​​Guangdong’s promotion policy is good, but LED light sources are not yet mature and the practice of promoting them with great fanfare is too aggressive and It will waste a lot of resources. At the same time, he is more concerned about the negative effects that may be brought about during the implementation process.
Zhou Jun, general manager of Qingdao Jinxin Lighting Decoration Engineering Co., Ltd., expressed even more dissatisfaction: “For immature LED lighting products, it is a misleading, wasteful and irresponsible manifestation of the entire society. ."
“At present, the industry does not take the advantage of mature traditional lighting, but instead pays more for the bad results. The hard-earned money of the common people is wasted.†He believes that the industry should be able to reflect on : "You can't push LED light sources all over the place. It seems that even if you use LED light sources, even high-tech projects, this is not true. Compared to foreign countries, there is no large-scale push of LED light sources, and China has been so quick to promote, although it has accumulated. A lot of experience, but also to pay too much of the cost, so that the LED lighting industry is still not known for others to do the wedding.â€
In fact, at present, the LED street light is still a part of the pilot phase, and the National Twelfth Five-Year Plan does not explicitly propose to completely phase out existing sodium lamps and turn to LED street lamps.
Mr. Wang Xiaoming, director of the project construction department of Shanghai Street Lamp Management Center, clearly stated that the large-scale use of LED street lamps will take time: “As a new type of product, LED lighting standards have not been standardized and the quality of products has been uneven, so that they are in the product. The advantages of energy saving, product life, replacement and maintenance are not obvious. On the contrary, the disadvantages such as cost and failure rate have a serious impact on the large-scale use of LED street lamps."
Example: Misfortune is not a single frustrating LED street light cluster failure
It is understood that the national grass-roots street lamp quality assessment is mainly directed at indicators such as the intactness of street lighting equipment and the road lighting and lighting rate. In the case of LED street light technical standards have not yet been introduced, the quality of the original LED street light is difficult to control, coupled with maintenance workers in the technology has always stayed in the sodium lamp, the maintenance of the LED street lamp is unfamiliar. If you leave it to the manufacturer for repair, it will be difficult to compare with the sodium lamp in terms of time and cost. There was a problem with the sodium lamp. After years of experience accumulated by the workers, the damaged parts could be judged immediately, and the parts could be repaired after being replaced, and the maintenance cost was low. However, many LED street lights have all their functions integrated. Even if the judgment is to drive a problem, it is not easy to replace the driving parts at the site.
In general, LED light sources are theoretically not easily damaged, and their lifetime can reach 50,000 to 100,000 hours. However, there are many manufacturers of LED street lamps, with various product designs and various appearance types. Drivers and chips belong to different manufacturers. After the packaging, the performance does not achieve the optimal combination of components. On the contrary, some basic requirements such as minimum waterproofness are very high. Difficult to guarantee.
A costly LED street lamp near Jinsha Street in Jincheng City, Xincheng District, Jinhua City is facing a cluster of failures. It has provided a "live" strength in the field. It is reported that there were 37 of the 68 local lights. There have been different degrees of black light problems and the proportion is more than half. Since the problem occurred, more than half a year has passed, and it is still falling into a dilemma. Residents are eager to hope that the street lamp management department can repair these lights, but the answer is "cannot be repaired."
Director of the Streetlight Management Office of Jinhua City, Dai Xiangwen stated that the street lights on this section are not within the routine maintenance scope of the street lamp management office. The owner of the Jinsha Street street lamp is the Xincheng District Administrative Committee of Weicheng District. At that time, the management committee once agreed with the street lamp supplier that the company should perform normal maintenance and management. According to the management of Jinhua City Street Lamps, they have repeatedly instructed companies to carry out repairs, but so far there has been no movement.
“As a new type of alternative energy-saving light source promoted and applied by the country, LED street light is undoubtedly a future development direction, but in practical applications, it will still encounter a lot of trouble.†Dai Xiangwen said, “This is determined by the current characteristics of LED street lamps. "He believes that LED street lights have their shortcomings, such as the life of the power supply is not guaranteed, and the power is low. In order to obtain high power, multiple parallel applications are required. In addition, LED street lamps are relatively “preciousâ€, and due to heat dissipation and other reasons, the pressure on maintenance and management in peacetime is very high. "Changing the cost of an LED lamp to 900 yuan is a lot more expensive than traditional street lamps." He admitted that this feature determines that LED street lamps are more suitable for urban landscape lighting, and that street lamps as pure lighting are slightly inferior.
Coincidentally, misfortunes do not stand alone. In Jinhua City alone, it is not only Jinsha Street but also the LED lights of other road sections have similar black lights. For example, in the southern part of Jinhua’s Xianyuan Ouwen Road section, there are also many street lights with black lights. For LED street lamps that could have been used for 50,000 hours (12 hours in a day and 11 years in use), there will be a black light problem in less than two years. According to Lu Liang, deputy general manager of Zhejiang Mingchuang Optoelectronics Technology Co., Ltd., an LED street lamp supplier at Jinsha Street and Xianyuan Oujing Road, this may be related to excessive voltage fluctuations, and may also be affected by the weather. In his opinion, it may be that the insurance inside is broken, and it would be better to change the insurance.
According to industry sources engaged in the production of LED lamps, there are many reasons for the dead lights of LED lamps. For example, waterproof is not good enough, the quality of the rectifier does not reach the relevant national standards, and there is a poor cooling effect. The lampshade of the LED lamp is now made of aluminum, and the heat dissipation function cannot achieve a certain effect. At present, there are a lot of LED lamp production enterprises, use plastic products to make lampshades, which to a certain extent also ensure the service life of LED lamps. However, the most important thing is whether or not companies can strictly follow the relevant national standards in the production process, and whether the follow-up service of the installation unit can keep up.
Proposal: Avoid Names "Public" Surname "Private" å°´å°¬ Perform Transparent and Efforts to Prevent Fraud
Now that the new policy has been promulgated, as if rice is cooked, it is bound to become a success. Perhaps at this juncture, the industry should indeed consider the "positive" mentality and provide more good suggestions for the implementation of the New Deal.
"Guangdong Province to promote the use of LED lighting products implementation plan" since the printing and distribution, the use of LED lighting products in various areas of public lighting in Guangdong have been carried out transformation work. The news quickly caused the industry's "covet", and some of them hope to share a bit, but there is another voice that: Although the policy is good, and SMEs may not be afraid, but with the intensification of competition, more and more Small companies lacking core technologies will be eliminated.
In response to this, it was suggested that Guangdong LED public lighting tender should fully respect market choices. As long as the technology of energy-saving lamps is mature and of good quality, especially if the price returns from the aristocrats to the grassroots and does not require compulsory implementation, the people will make rational choices that are like “advantageous to avoid disadvantagesâ€. Otherwise, LED lighting promotion only surnames “public†and “surname†does not mean “privateâ€. The government is too “loveâ€, and companies may be accustomed to “food forever,†but not eliminated but with greater risk hidden.
According to an interview with Aladdin Lighting News, the design director of Taiwan's Yuan Zongnan Lighting Design Office also stated that the introduction of the new policy will inevitably bring about rapid development. However, at the same time as rapid development, there are still some issues that deserve our consideration. This includes the issue of "difficulties in obtaining benefits for SMEs."
He expressed concern about this: “The impact of different companies is not the same, many domestic LED industry testing standards have not been established, the entire market is fierce and chaotic. Due to the gap between technology and product quality, this policy The advancement of the company is undoubtedly a good thing for companies that have mastered core technologies. However, for ordinary enterprises, the living space of enterprises will be reduced, and the two-level division between enterprises and enterprises will become more and more serious."
He hopes: "(This time) policy advancement can help and encourage SMEs, so that SMEs can develop cooperation, learn from each other, strengthen technology development to enhance the competitiveness of products, get a place in the competition, but also for the future To lay a solid foundation for development, the implementation of the New Policy should be targeted and implemented in a gradual and orderly manner. Promotion of the use of LED's policies can be appropriately extended and relaxed so that more companies have the opportunity to participate in development."
Yuan Zongnan pointed out at the same time that the introduction of the new policy will inevitably bring about rapid development. However, at the same time of rapid development, there are still some issues that deserve our consideration. The introduction of LED's new policy, one by one, has also fostered the blindness of some businesses, while ignoring the development of product quality and technology renewal in the province. At present, LED is still in an important period that requires extensive user acceptance. A trust depends on the quality of the product, but loss of trust will lose the key opportunity for the promotion of this policy. From a distance, it is not conducive to the development and popularization of LED.
Wang Xiu, R&D director of Tianbao Group International Co., Ltd. also has some opinions and concerns about the implementation of the policy. He feels that in terms of past “conventionsâ€, “government projects are prone to corruption, and the quality acceptance of government departments is the key link for the establishment of competition among various manufacturers. How government departments guide the handling of fair and healthy competition has become the key. Otherwise, low-cost duplication and excessive production will affect the entire industry chain, and labor and people will suffer.
Xu Qingliu, Chief Lighting Consultant of Plessis Lighting Design & Consulting Co., Ltd. in Singapore stated that the policy is beneficial and disadvantageous. The promotion of LED lighting by the government is based on the spatial development of the LED lighting market, but in the end it is necessary to popularize public lighting. Give a question mark. He pointed out: "Through the promotion of government agencies, companies are the biggest winners. Finally, the promotion methods are not correct and the effect is not obvious. It will only cause harm to the people. At present, all parts of the country have transformed the city's LED road lighting. In fact, the industry has always been This practice is very controversial."
The implementation of the Guangdong New Deal is imperative, and Zhao Shengxin, the chief designer of Shangzhu Lighting, hopes to be transparent and fair in the implementation process. Elimination of power for rent-seeking and engineering fraud. He suggested that in terms of assessment, both energy efficiency indicators and economic efficiency should be measured, and more emphasis should be placed on long-term performance assessment. It is not only necessary to look at data on energy conservation and one-year results, but also to pay attention to the effects of years later. .
Positive point of view: Guangdong dares to "eat crabs" not to look at the policy significance
The introduction of a policy is not a reason for its existence. The world is not perfect. It does exist, and it may be regrettable. The official needs to correct its attitude and use a rational heart and calm mind to see the necessity of its existence. And advantages. In the voice of opposition, there are also industry experts who believe that LED lighting has achieved or exceeded 50% in the LED demonstration projects already implemented.
Regardless of any city, road lighting systems, nightscape landscape lighting systems and other important infrastructure are indispensable. The city lighting system brings convenience to people's lives while also consuming large amounts of electric energy. Urbanization brings greater demand for lighting and brings greater pressure. Energy-saving, low-carbon, green lighting, sustainable lighting... all are the direction that the development of lighting industry is looking for today.
On May 23 this year, the People's Government of Guangdong Province issued the "Guangdong Province's Implementation Plan for the Promotion of the Use of LED Lighting Products" (hereinafter referred to as the "Project") to implement a comprehensive strategic plan for the promotion of energy-saving and emission reduction, and the promotion of LED lighting and related industries. According to the plan implementation plan, Guangdong Province will popularize LED lighting in the public lighting field within three years. It is estimated that by the end of the “Twelfth Five-Year Planâ€, the LED industry can achieve an annual output value of more than 500 billion yuan.
Bring Green Lighting Ideas to Action
LED lighting as a green lighting, its energy conservation is no doubt, but also one of the general direction of the development of the lighting industry, is the common dream of the industry. The introduction of this policy is undoubtedly the gospel of the LED industry, bringing hope to the thirsty industries. Since the announcement of the plan, Dongguan, Shenzhen, Taishan, Shantou, Zhongshan, and even Guangdong, the east, west and west have successively introduced plans to vigorously promote LED lighting.
In an interview with the reporter, Tang Guoqing, general manager of CREE China Market, said that this policy is a double-edged sword. Under the premise of promoting energy conservation and emission reduction and the “Twelfth Five-Year Plan†on promoting green lighting, there is no doubt that Guangdong As an LED industry base, this move is in line with the country's guidelines and policies, and has set an example. Undoubtedly, the entire LED industry in China, especially the enterprise, is a big boost and an invigorator. “Guangdong Province is the province that has taken the lead in implementing this policy. It dares to innovate, dares to lead, and dares to create opportunities to promote the development of LED lighting. The Guangdong government is far-sighted. I think this idea and this approach are very innovative,†he said.
Data confirms significant LED energy savings
Guangdong is the first to take the crab as the "first person to eat crabs," which naturally caused a variety of sounds in the industry to set off waves. For this New Deal, the voice of opposition is even more prominent. The reason is that the current development of LED lighting technology is not enough to inherit the worry of "general reunification" of public lighting. In spite of this, relevant experts from the Guangdong Science and Technology Department stated that the prejudice regarding LED lighting is untenable, and they have used the data to argue that the energy-saving rate of LED demonstration projects that have already been implemented has reached or exceeded 50%.
In the New Deal program issued in Guangdong, it is shown that by promoting the implementation of applied projects, it will achieve lighting energy savings of more than 50% compared with the same caliber. According to media reports, in the renovation project in Chancheng District of Foshan City, more than 11,000 new high-power LED lamps were installed, saving more than 10 million kilowatt-hours of electricity per year compared to high-pressure sodium lamps, saving electricity rates of 62%, and saving more than 890,000 yuan in electricity bills. It is equivalent to saving 3,915 tons of standard coal, reducing 10,257 tons of carbon dioxide and 117 tons of sulfur dioxide, equivalent to an additional 598 acres of forest annually.
In addition, in Shenzhen Expressway LED street lighting and tunnel lighting project, the same tunnel lighting project was selected to compare the project cost of high-pressure sodium lamps and LED tunnel lights. The results show that if high-pressure sodium lamps are used, each kilometer tunnel requires 100 kwh of high-pressure sodium lamps of 530 ç›, the total investment of the lamps is 769,000 yuan, and the distribution line investment is 167,000 yuan, with a total investment of 936,000 yuan; but if LED lamps are used, the satisfaction is satisfied. Under the premise of the same lighting standard, only 286 LED tunnel lights are needed. The total investment in lamps is reduced by 44% compared with the use of high-pressure sodium lamps, and the investment in distribution lines is reduced by 50%. In addition, plus the LED operating life savings during the period of 101.7 million yuan, lighting maintenance spending 212,000 yuan, the entire new lighting projects from the investment to the latter part of the operating expenses, the same time saving 1.742 million high-pressure sodium lamp.
Promotes LED lighting with a wide range of applications
Energy-saving LED lighting is well-known, but most of the current use of outdoor lighting in the public domain, indoor lighting, especially home lighting can not be popular, so this market can currently be said that the potential shares, how can the LED light source into the ordinary people Home is a headache for countless businesses. According to a report released by the relevant departments of Guangdong Province in the past, LED companies in the United States, Japan, and Europe have more than 80% of LED chip core technology patents, and domestic similar companies have less than 10% of the same patents. For a long time, the core basic technology of epitaxial wafers and chips in the upstream of LED industry has been monopolized by several large industrial giants, occupying about 70% of the entire industry chain. This has also made the structure of China's LED industry chain very unreasonable, and the pressure has fallen heavily on LED. On the shoulders of the business.
The data show that as of the end of 2011, Guangdong Province, LED lighting demonstration project has promoted the use of LED street lamps 250,000 baht, pulling the LED lighting industry's annual output value reached 151.5 billion yuan, ranking first in the country. The government directly supports the LED lighting industry with “hands and feet†by “handsâ€. By popularizing the application of public lighting, it further promotes the extensive application of LED lighting in indoor and other fields.
Can use the EMC model or draw on the "US approach"
There is a foreign saying: "Any coin has two sides." It is true that everything exists in both positive and negative terms. The fact that the introduction of the Guangdong New Deal caused public opinion disturbance tells us that this policy is not absolutely perfect. It brings hope to the industry and also gives the industry more room to think and discuss.
The EMC model is no stranger to the LED lighting industry. It is a market-oriented energy-saving mechanism that can reduce the cost of energy-saving projects by reducing energy costs. Zhao Shengxin, the chief designer of Shenzhen Shangzhu Art Design Co., Ltd., also advocates the use of the EMC model. He said: "The contracted energy management (EMC) operating model should be a good mode of operation, but it should be more pragmatic to improve the operation of the market. In the implementation process, we should be able to achieve transparency and fairness at the source of policy implementation, and prevent power rent-seeking and engineering fraud.In terms of assessment, we should both measure energy efficiency indicators and measure economic efficiency, and we must pay attention to long-term assessment. You can't just look at the energy savings of the data, the effect of a year, but also pay attention to the effects of years later."
Anti-side point of view: large-scale application of artificial ripening LED "has not arrived yet"
Previously, regardless of the country's policy to promote the tilt, or the market itself, the heat has laid the LED lighting this "grandchildren" status. Including China’s ban on incandescent bulbs in October, it is almost an attempt to pave the way for LED to replace its market share. From time to time, to do the lighting of the open talk about LED, as if not just a night before returning to liberation so simple, but do not know to fall back to "Middle Age" which dark shadow. However, no matter who is in the industry or outside, there are not many people who really understand LED, and overwhelming people are gaining ground and tending to add strength. It also makes the prosperity of the LED lighting market a layer of fog and piles of bubbles.
Can the road lighting LED light activate the "cheese" of the high pressure sodium lamp?
The opinion of the unit struggling with a line lamp might be more persuasive. Zhang Tao, from the Lianyungang City Lighting Management Office in Jiangsu Province, once fought over the high-pressure sodium lamp: “The high-pressure sodium lamp itself is also a kind of green light source, and it is more mature. In cities, the high-pressure sodium lamps used in Osram and GE, under normal circumstances 250W sodium lamps, are absolutely no problem in five years, and the standard interfaces are the same.As a fourth-generation light source, LED is just one of them, the electrodeless lamp If the technical bottleneck breaks, it will not be worse than the LED."
High-pressure sodium lamps and LED lamps belong to lamps of two different light sources, because their light emitting principles are quite different, and the resulting lighting effects are completely different. Both have their own advantages, but compared with the development of relatively mature high-pressure sodium lamps, LED lamps still need to be breakthrough and development.
Wang Xiaoming of the Ministry of Construction of Shanghai stated: From the use aspect, the sodium lamp is still the biggest rival of the LED street lamp. There are manufacturers in the publicity efforts to exaggerate the energy-saving effect of LED street lamps, in the direction of which is open to question. If the sodium lamp technology is used as a reference system to examine LED street lamps, the difference in product prices can be offset by energy saving. The result can be imagined, after all, the sodium lamp's price/performance ratio is still very high.
According to Liu Wei, sales manager of Hella Industrial China, Guangdong is a pilot project, but it is a demonstration, but it is still not mature enough to use it on a large scale. Guangdong LED manufacturers are many, have formed a scale, but things are not really good, but also need to really work hard to do; now the LED lights compared with the traditional high-pressure sodium lamp, whether to meet the standard, there is no obvious advantage to Give a question mark.
Xie Junyan, director of the Shanghai Street Light Management Center, also raised objections. In his view, the application of LED luminaires at least on the expressway is not appropriate. Because of the penetrability of the LED, lighting is ineffective in fog, affecting traffic safety. He said: "At present, the use of high-speed LED applications is still too advanced. I once had discussions with industry experts on related issues. I mentioned many advantages of using LED lamps for highways, but in my opinion, the shortcomings are also obvious. "It's also fatal." He felt that LED lights could be applied to express roads and urban roads, but "if blindly applied on the highway, it would be inappropriate to discredit the LED lamps."
Xia Jun, the manager of the Shenzhen Light Tube Management Center, put forward diametrically opposed opinions. He said that extreme weather is a rare exception and sodium lights are not necessarily advantageous in extreme weather. "Under normal conditions, we can meet the needs, then there is no problem." In this regard, some people in the industry have stated that although experts have different opinions, the application of high-speed LED lamps and lanterns, driving safety requirements is very strict, and should always be the primary consideration.
Technical issues: Will the push of LED streetlights lead to "catastrophe"?
For the Guangdong Province to promote the practice of LED street lamps, the industry has been questioned before. In August, a company named Ruisenike Lighting System Technology Co., Ltd. issued an open letter to the Guangdong provincial government, which caused a heated debate.
The letter title is "Guangdong will change all street lights to LED street lights will be a disaster!"
The open letter believes that a good street lighting solution must consider five points. The first is the so-called "energy saving." The letter revealed that energy conservation is equivalent to the average power consumption of the average illumination, and the average illumination cannot be only the average illumination of the ground. The light intensity of the space has good predictability for vehicles arriving from afar and prevents traffic accidents from happening. Currently, LED street light manufacturers installed are difficult to achieve, and energy is saved at the expense of illuminance. Sodium lamps currently between 100-200 Lm/W are already a very efficient light source, and this LED has no advantage.
The second is that the outdoor ambient temperature is uncontrollable. The street lamp must be waterproof and dustproof. The lamp must be sealed. The temperature of the water vapor inside the lamp after sealing is more than 100 degrees under extreme weather conditions. The LED continuously works in a high-temperature environment, according to the current LED. The thermostat feature, even if you do the lamp is no better, will inevitably die or light fade. Thirdly, no light source has so far been better than sodium lamps. Fourth, the street lamp is stained with insects in the field and will seriously affect the light efficiency. The spectral characteristics of the sodium lamp avoid this phenomenon, while the LED cannot be avoided. Fifth, we must consider earthquake protection and typhoon prevention. At present, many street lamp replacement projects simply replace the traditional street lamp bases with LED lamp bases. This is very dangerous. The weight and frontal area of ​​the street lamp base must be carefully calculated, and whether the original lamp pole and foundation anti-seismic and anti-typhoon levels are in line with the local conditions.
This open letter, popular in the industry, analyzes the feasibility of LED lamps replacing sodium lamps in the field of public street lighting from the technical level. It is concluded that "LED is a new type of high-efficiency light source and currently has an irreplaceable advantage in replacing incandescent lamps and fluorescent lamps, but there is no advantage other than sodium lamp in replacing sodium lamps". He also pointed out that "if there are full replacement (especially main road) lights, traffic accidents will be significantly improved" and "real-day weather problems will cause large batches of dead lights or severe light failure" and other practical problems.
Zhao Shengxin, chief designer of Shangzhu Lighting, said that he had previously seen reports that if a high-pressure sodium lamp was used in an LED street light and tunnel light lighting project, a 100 kilowatt-hour high-pressure sodium lamp would be required to produce 530 turns per kilometer of tunnel, but if LED lights were used Only 286 LED tunnel lights are required to meet the same lighting standards. Zhao Shengxin bluntly expressed his skepticism about this. “According to my current experience, I feel that this is simply not possible. Now that LED lamps replace two 100-kilowatt-hour high-pressure sodium, it is impossible to satisfy the current LED lamps. Even LED lighting Lumen can reach or even surpass traditional light sources, but the brightness cannot be achieved.In practical applications, the number of LED lamps will exceed the number of traditional lamps more often.So we should have a comprehensive understanding of the energy-saving effect, can not be alone The power factor of one LED lamp is compared with the power of a high pressure gas discharge lamp. Energy saving effect I think we should consider the cost-effectiveness of energy saving, which is more practical and meaningful."
Chen Qiang, general manager of Jiangsu Skyline Lighting Engineering Co., Ltd. first affirmed that by stimulating the LED lighting industry in Guangdong and radiating to the whole country, it has a positive impact on the development of the industry. But at the same time, he also stated that “If large-scale promotion in Jiangsu is not suitable, and the provincial government has no plans and policies to implement, only experimental non-main street LED street lighting, the effect of feedback can be, but light The problem of failure still exists."
According to Ni Xinda, general manager of Prosper Electric (China) Co., Ltd.: From a technical point of view, LED lighting is not yet able to replace traditional lighting, and the cost is already several times that of traditional lighting. LED lighting does have the advantages of environmental protection and power saving. He reminded: "Do not go blindly to promote energy conservation, or even show, unless the LED lighting product technology, quality and other aspects of all through." He said Pross will not do high-power LED lighting products, including mining Lamps, street lights, and mainly to do low-power LED lighting products, such as landscape lighting. Because the high-power LED lighting itself has many problems, such as heat, heat dissipation, and poor light attenuation.
When Zheng Gang, the deputy general manager of Fuzhou Tonglian Installation Engineering Co., Ltd., accepted an interview with Aladdin Lighting News, he frankly stated that it is unreasonable to say that "LED lighting" is equivalent to "energy saving." On the contrary, using the minimum power to achieve the best light efficiency is energy saving. And not all places can use LED lighting, specific analysis of specific issues. He believes that the current road lighting sodium lamp can achieve the effect of energy saving, there is no need to carry out large-scale transformation. “There are still many problems in the market such as short life span, power damage, and lack of compliance in the market. In Fujian, LED lighting is rarely used on roads because of the problems of LED lighting itself. It's useful, but it's generally not effective, so the government must be cautious about popularizing LED lighting, and it must be realized that LED lighting does not completely replace traditional lighting."
Shanghai Aite Lighting Design Co., Ltd. general manager and director of lighting design Wang Jianping cited the LED lights still have many problems, including: 1. Sacrifice illumination. The decrease of the brightness level must be accompanied by a decrease in power; 2. The heat dissipation cannot be completely resolved, resulting in the light attenuation of the lamp; 3. The high-power LED lacks a reasonable light distribution design and glare control, and the strong light will make people feel dazzling and affect the comfort of the driver. .
Wang Jianping believes that the popularity of home lighting and commercial lighting is fast, LED replacement of high-energy spotlights, halogen lamps is more reasonable, cost-effective, energy-saving advantages are more obvious. The public lighting itself is a large-scale and large-area lighting. Nowadays, gold halide lamps used in functional street lamps have a greater advantage in terms of efficiency and longevity, and LED replacement will not be rapid.
He pointed out: "Before the government's application of LED industry is well understood, it is necessary to handle the popularization of LED street lights."
Time and scope issues: How can a fruit orchard not ripen to ripen an orchard?
In addition to the maturity of the LED technology, the timing of the “revision of Guangdong public lighting within three years according to the plan†was also questioned. Recalling that the “plan†was issued for more than three or four months, the performance of many cities in Guangdong province was not daunting, and people were not willing to set a timetable for completing the task. However, the LED application itself has a broad prospect and is not optimistic about the contradiction between the current, LED as a new generation of green light source, the government should make efforts to promote the application is understandable, but "strong twist can not be out of melon," the truth is also warning us, The promotion of subjective intention and the objective and practical popularization are often implemented in two different ways. The so-called "days to rain, mothers to marry", it should at least be "free love," rather than "arranged marriage." To truly achieve the significance of popularization, it is to let the market gradually accept the LED, and non-artificially hard-selling LEDs to the market and the public with a "time-limited subscription" model.
Guo Wenjun, director of the Urban Planning Institute of the Urban Planning Institute of China’s Urban Planning Institute and chief engineer of the Lighting Planning Department, said in an interview with Aladdin Lighting News: “Once we are based on the premise of doing a good job, we have a wide range of popularization and market feedback time. It may be in a year or so. If there are problems, especially security problems, and who will not be responsible for the responsibility of the problem first, but the head is not well prepared, what will be the follow-up situation? These are predictable futures. Administrative promotion of LED is an inevitable trend and means, but the meal is a bite to eat, do step by step, do not talk about the status quo industry confusion, product uneven, too many manufacturers, do not be distracted by the discourse can be confused. The project leader we implement and promote must have a clear understanding of the lighting market and development."
Yang Xiaoping of Beijing Electric Light Source Research Institute emphasized the quality and reliability of LED lamps in the interview. He believes that if the current LED can completely replace the sodium lamp, if the quality and reliability of the product can be guaranteed, then there is no problem. However, it is still not a one-size-fits-all approach to compulsory promotion. You can “first go from a small highway to a main road and then to a highway.â€
In this regard, Chen Yansheng, chairman of the China Lighting Association and Zhang Tao of the Lianyungang City Lighting Management Office in Jiangsu Province, said at the same time that high-speed LED street lights can be piloted, but it is not suitable for large-scale promotion. Technology and cost are the bottleneck of promotion. For the application scope of LED street lights currently in the expressway, Zhang Tao added: “The appropriate range of LED street lights for highway applications is 100 meters on both sides of the toll station, but all highways use LEDs to retain their opinions.â€
"The current LED technology is constantly developing, and many technical bottlenecks are continuously resolved, but before the overall and normative measures are solved, pilot applications can be applied. It is better not to use large-scale applications in functional lighting." Zhang Tao The views are quite representative of the industry's view of high-speed LED applications.
Tian Yanghua, Director of Natural Opto-electronics Market Division, also believes that with the current overall status of LED lighting, large-scale promotion is still not coming. He is worried: “(This is) excessive overdraft for the market, LED is used normally or immature, the government Using this method to release this demand is actually not conducive to the maturity of LED technology."
Ren Yuanhui, honorary director of the China Illuminating Society's Indoor Lighting Professional Committee, did not advocate this promotion. In an interview with Aladdin Lighting News, he told reporters bluntly: “Government agencies should not impose technical requirements in a few years. It is unwise to popularize public lighting.†He felt that it should be based on economic and technological comparisons to formulate specific technical standards, such as the use of what is reasonable. “At present, LED lighting itself does not have the conditions of use, such as color deviation, glare control, and price, although its prospects are very broad. For example, the use of three-color straight-tube fluorescent lamps in the office is sufficient, first of all, the price is reasonable, and then the effect is good. From the consumer From a point of view, there is no need to discard products that are cheap and expensive and choose products that are expensive and technically immature."
In an interview, Yu Anqi, chairman of the Shanghai Illuminating Society, said that in the case that the technology is still immature, large-scale application will cause waste of a lot of resources. He affirmed the bright future of LED light sources, and believes that the future will occupy a larger and larger share. However, he asserted to the reporter: "Even after another 5 years, LED will not be a situation that dominates the world, because some occasions are LEDs. Can't replace it."
Wu Hong, general secretary of China Light and Functional Materials Branch of China Rare Earth Industry Association, also believes that the promotion of LED lighting requires a process. “The overall idea of ​​Guangdong’s promotion policy is good, but LED light sources are not yet mature and the practice of promoting them with great fanfare is too aggressive and It will waste a lot of resources. At the same time, he is more concerned about the negative effects that may be brought about during the implementation process.
Zhou Jun, general manager of Qingdao Jinxin Lighting Decoration Engineering Co., Ltd., expressed even more dissatisfaction: “For immature LED lighting products, it is a misleading, wasteful and irresponsible manifestation of the entire society. ."
“At present, the industry does not take the advantage of mature traditional lighting, but instead pays more for the bad results. The hard-earned money of the common people is wasted.†He believes that the industry should be able to reflect on : "You can't push LED light sources all over the place. It seems that even if you use LED light sources, even high-tech projects, this is not true. Compared to foreign countries, there is no large-scale push of LED light sources, and China has been so quick to promote, although it has accumulated. A lot of experience, but also to pay too much of the cost, so that the LED lighting industry is still not known for others to do the wedding.â€
In fact, at present, the LED street light is still a part of the pilot phase, and the National Twelfth Five-Year Plan does not explicitly propose to completely phase out existing sodium lamps and turn to LED street lamps.
Mr. Wang Xiaoming, director of the project construction department of Shanghai Street Lamp Management Center, clearly stated that the large-scale use of LED street lamps will take time: “As a new type of product, LED lighting standards have not been standardized and the quality of products has been uneven, so that they are in the product. The advantages of energy saving, product life, replacement and maintenance are not obvious. On the contrary, the disadvantages such as cost and failure rate have a serious impact on the large-scale use of LED street lamps."
Example: Misfortune is not a single frustrating LED street light cluster failure
It is understood that the national grass-roots street lamp quality assessment is mainly directed at indicators such as the intactness of street lighting equipment and the road lighting and lighting rate. In the case of LED street light technical standards have not yet been introduced, the quality of the original LED street light is difficult to control, coupled with maintenance workers in the technology has always stayed in the sodium lamp, the maintenance of the LED street lamp is unfamiliar. If you leave it to the manufacturer for repair, it will be difficult to compare with the sodium lamp in terms of time and cost. There was a problem with the sodium lamp. After years of experience accumulated by the workers, the damaged parts could be judged immediately, and the parts could be repaired after being replaced, and the maintenance cost was low. However, many LED street lights have all their functions integrated. Even if the judgment is to drive a problem, it is not easy to replace the driving parts at the site.
In general, LED light sources are theoretically not easily damaged, and their lifetime can reach 50,000 to 100,000 hours. However, there are many manufacturers of LED street lamps, with various product designs and various appearance types. Drivers and chips belong to different manufacturers. After the packaging, the performance does not achieve the optimal combination of components. On the contrary, some basic requirements such as minimum waterproofness are very high. Difficult to guarantee.
A costly LED street lamp near Jinsha Street in Jincheng City, Xincheng District, Jinhua City is facing a cluster of failures. It has provided a "live" strength in the field. It is reported that there were 37 of the 68 local lights. There have been different degrees of black light problems and the proportion is more than half. Since the problem occurred, more than half a year has passed, and it is still falling into a dilemma. Residents are eager to hope that the street lamp management department can repair these lights, but the answer is "cannot be repaired."
Director of the Streetlight Management Office of Jinhua City, Dai Xiangwen stated that the street lights on this section are not within the routine maintenance scope of the street lamp management office. The owner of the Jinsha Street street lamp is the Xincheng District Administrative Committee of Weicheng District. At that time, the management committee once agreed with the street lamp supplier that the company should perform normal maintenance and management. According to the management of Jinhua City Street Lamps, they have repeatedly instructed companies to carry out repairs, but so far there has been no movement.
“As a new type of alternative energy-saving light source promoted and applied by the country, LED street light is undoubtedly a future development direction, but in practical applications, it will still encounter a lot of trouble.†Dai Xiangwen said, “This is determined by the current characteristics of LED street lamps. "He believes that LED street lights have their shortcomings, such as the life of the power supply is not guaranteed, and the power is low. In order to obtain high power, multiple parallel applications are required. In addition, LED street lamps are relatively “preciousâ€, and due to heat dissipation and other reasons, the pressure on maintenance and management in peacetime is very high. "Changing the cost of an LED lamp to 900 yuan is a lot more expensive than traditional street lamps." He admitted that this feature determines that LED street lamps are more suitable for urban landscape lighting, and that street lamps as pure lighting are slightly inferior.
Coincidentally, misfortunes do not stand alone. In Jinhua City alone, it is not only Jinsha Street but also the LED lights of other road sections have similar black lights. For example, in the southern part of Jinhua’s Xianyuan Ouwen Road section, there are also many street lights with black lights. For LED street lamps that could have been used for 50,000 hours (12 hours in a day and 11 years in use), there will be a black light problem in less than two years. According to Lu Liang, deputy general manager of Zhejiang Mingchuang Optoelectronics Technology Co., Ltd., an LED street lamp supplier at Jinsha Street and Xianyuan Oujing Road, this may be related to excessive voltage fluctuations, and may also be affected by the weather. In his opinion, it may be that the insurance inside is broken, and it would be better to change the insurance.
According to industry sources engaged in the production of LED lamps, there are many reasons for the dead lights of LED lamps. For example, waterproof is not good enough, the quality of the rectifier does not reach the relevant national standards, and there is a poor cooling effect. The lampshade of the LED lamp is now made of aluminum, and the heat dissipation function cannot achieve a certain effect. At present, there are a lot of LED lamp production enterprises, use plastic products to make lampshades, which to a certain extent also ensure the service life of LED lamps. However, the most important thing is whether or not companies can strictly follow the relevant national standards in the production process, and whether the follow-up service of the installation unit can keep up.
Proposal: Avoid Names "Public" Surname "Private" å°´å°¬ Perform Transparent and Efforts to Prevent Fraud
Now that the new policy has been promulgated, as if rice is cooked, it is bound to become a success. Perhaps at this juncture, the industry should indeed consider the "positive" mentality and provide more good suggestions for the implementation of the New Deal.
"Guangdong Province to promote the use of LED lighting products implementation plan" since the printing and distribution, the use of LED lighting products in various areas of public lighting in Guangdong have been carried out transformation work. The news quickly caused the industry's "covet", and some of them hope to share a bit, but there is another voice that: Although the policy is good, and SMEs may not be afraid, but with the intensification of competition, more and more Small companies lacking core technologies will be eliminated.
In response to this, it was suggested that Guangdong LED public lighting tender should fully respect market choices. As long as the technology of energy-saving lamps is mature and of good quality, especially if the price returns from the aristocrats to the grassroots and does not require compulsory implementation, the people will make rational choices that are like “advantageous to avoid disadvantagesâ€. Otherwise, LED lighting promotion only surnames “public†and “surname†does not mean “privateâ€. The government is too “loveâ€, and companies may be accustomed to “food forever,†but not eliminated but with greater risk hidden.
According to an interview with Aladdin Lighting News, the design director of Taiwan's Yuan Zongnan Lighting Design Office also stated that the introduction of the new policy will inevitably bring about rapid development. However, at the same time as rapid development, there are still some issues that deserve our consideration. This includes the issue of "difficulties in obtaining benefits for SMEs."
He expressed concern about this: “The impact of different companies is not the same, many domestic LED industry testing standards have not been established, the entire market is fierce and chaotic. Due to the gap between technology and product quality, this policy The advancement of the company is undoubtedly a good thing for companies that have mastered core technologies. However, for ordinary enterprises, the living space of enterprises will be reduced, and the two-level division between enterprises and enterprises will become more and more serious."
He hopes: "(This time) policy advancement can help and encourage SMEs, so that SMEs can develop cooperation, learn from each other, strengthen technology development to enhance the competitiveness of products, get a place in the competition, but also for the future To lay a solid foundation for development, the implementation of the New Policy should be targeted and implemented in a gradual and orderly manner. Promotion of the use of LED's policies can be appropriately extended and relaxed so that more companies have the opportunity to participate in development."
Yuan Zongnan pointed out at the same time that the introduction of the new policy will inevitably bring about rapid development. However, at the same time of rapid development, there are still some issues that deserve our consideration. The introduction of LED's new policy, one by one, has also fostered the blindness of some businesses, while ignoring the development of product quality and technology renewal in the province. At present, LED is still in an important period that requires extensive user acceptance. A trust depends on the quality of the product, but loss of trust will lose the key opportunity for the promotion of this policy. From a distance, it is not conducive to the development and popularization of LED.
Wang Xiu, R&D director of Tianbao Group International Co., Ltd. also has some opinions and concerns about the implementation of the policy.
