LED lighting conservative
It is normal for emerging industries to enter the industry cautiously, but over-concern, they will miss the opportunity by merely interrupting market results with their own instincts. According to market understanding, the main reasons for the conservative thinking of led lighting are as follows:
First, worry about heat dissipation will not be resolved
Heat dissipation mainly depends on the way we design. It is not a solution. It is actually a cost issue. The design of LED lamps has long been affected by the use of light bulb (point light) structure concept, and it will always be considered that heat dissipation is difficult to solve. There is no indication that only a design like a light bulb can be widely adopted in the lighting market. It should be aside from the traditional concepts and breakthrough concepts and developments.
For example, take the existing LED street lamp to say, why design 100w or so, why not 250w like high pressure sodium lamp? Obviously it is cost considerations. LED design 250W, LED costs and cooling costs will be much higher, making the cost unacceptable to the market. It's not that you can't design such a high power, nor can it be solved by heat dissipation. At this stage, as far as the LED price is acceptable, all of them are applied well and are not limited by the heat dissipation conditions and cannot use LEDs. There is a difficulty in heat dissipation. We need to solve the problem of LED development. Heat dissipation is a cost issue. It cannot be solved.
Temperature, usually a lot of requirements of the LED product surface temperature within 50 °C, this mentality is wrong. It depends on our specific use of environmental conditions that at many ambient temperatures cannot be guaranteed at 25°C. It is obviously difficult to achieve a product surface temperature of 50°C. The LED junction temperature needs to be considered when designing a led product. If the surface temperature is low, the heat is not released, and the junction temperature exceeds a reasonable value, it is clear that the product design has failed! In turn, the heat dissipation thermal resistance of the LED product design is small, the junction temperature is kept within a reasonable range, and the product case temperature reaches 80°C, which is nothing bad. Can not be judged to be unqualified, hot products will be judged bad. How many people dare to touch the existing traditional lamp appearance by hand and experience the feeling of burns, it is obvious that this requires the LED lighting product temperature is a personal mentality problem.
Second, worry about safety regulations
LED does not have a clear file to follow and will not affect the LED process. Many products do not have corresponding standards, not all of them are developed well! LED does not follow the standard, LED Christmas lights are also non-isolated not used for many years! Some netizens always look at the development process led. Existing street lamps, energy-saving lamps (including fluorescent lamps) and spotlights are all non-isolated. It is not clear why some friends must isolate LED products. I think it is a typical conservative mentality.
Before viewing the lighting fixtures are not isolated, isolation is mostly an adapter and electronic products that require personnel to operate contact. Obviously this requirement for LED lighting fixtures is not justified. LED power supply and current voltage switching power supply products will not be much different in safety regulations. The safety regulations apply to LED products, but the light source is different and there is no essential difference. Even if the new regulations for LED safety are issued, they must be conducive to the future direction of LED development. There can be no restrictions.
Third, worry about the short life of the use of electrolytic capacitors affect the LED process
We cannot judge the lifespan of LED products by the life of the electrolytic capacitor, and the theoretical value and the actual value will be very far apart. Propaganda has a lifespan of 100,000 hours. This theoretical value is difficult to verify. Electrolytic capacitors are widely used in existing lighting fixtures and have not seen such serious consequences. Electronic products are not guaranteed to be 100% non-destructive, LED products are the same, other devices lag behind LED devices, the market will force electrolytic capacitors to renew or new devices born. Does not affect the development process of LED lighting, and it is indeed redundant.
Fourth, the price is too high for a large number of applications
LED development can learn from "Moore's Law." Gordon? Moore (gordonmoore) prepares a report on the development trend of computer memory. He collated an observational data. When he started drawing data, he found a surprising trend. Each new chip generally contains twice the capacity of its predecessor, and each chip is generated within 18-24 months after the previous chip was generated. If this trend continues, the computing power will increase exponentially with respect to the time period. Moore's observations are now the so-called Moore's Law. The stated trends have continued to this day and are still unusually accurate.
There is obviously no way to double the brightness value in 18-24 months, but the price reduction and brightness increase are more than double the application of 18-14.
Led lighting radicals:
The formation of the market requires certain rules. Propaganda is too far off to affect the development of the entire industry. In the long run, it will also bring negative impact on their own companies and damage their own credibility and interests. Led light conversion efficiency and energy-saving lamps are basically the same, how can we design a product that is more energy-efficient than traditional lamps! The most basic concept is that propaganda can regenerate several mountain gorges. Almost that energy shortages are due to led can not be applied in time. General habits of publicity when the entire lighting industry are using led how? What is the use of the world? Can a practically diversified world be like this?
Strictly speaking, "led can be used for lighting" and "led can be used for street lighting." It is an experimental stage. The price is high, there are environmental protection advantages, the performance-price ratio is out of balance, energy saving is not mentioned, and energy saving is the future. Not only does it not save energy but also consume a lot of aluminum at this stage.
Such as street lights, design power is about 100w, why should we choose this power? Also mentioned in the front is the cost considerations, the basic brightness can meet the national standards, led prices should be reduced as much as possible, allowing customers to accept. Some netizens took 100wled streetlights and 250w sodium lamps for energy saving. They also took the national standard as a reference. They don't explain the brightness beyond 250w. Is this fair? In turn, we can also design street lamps that comply with national standards with 100W sodium lamps. What is the difference between this and the current government's emphasis on increasing the air-conditioning temperature by a few degrees?
The radical faction is mainly the production of led lighting fixture-based manufacturing companies and led production packaging companies. Of course, it can be understood that the position is generally related to the team we are standing in. Usually, they will arm their own slow-moving products and demonstrate their contribution to energy conservation.
In the selection of publicity, environmental protection is usually the object of publicity, but these will not have enough reason to replace the existing lamps. The most powerful killer in the future is still energy-saving, but the price is also a decisive factor. At present, led spotlights do not have the market results we expect. Cost is the biggest factor.
Current drive circuit status:
At present, the market is not very mature with regard to the city lighting circuit, which is far from the level of traditional lighting fixtures. Efficient light sources require efficient driveline support. I personally think that more than 90% of efficient drive lines must be achieved. If you emphasize the security of isolation, it is obviously impossible to achieve this high efficiency. Traditional lamps are not isolated to achieve high efficiency, led will be the same. We feel that insecurity is mainly caused by the use of aluminum radiators for heat dissipation. It is clear that we need to change the way of thinking when designing products!
In terms of ic design, the led lighting market is an emerging industry. There is no reference line design. Most ic design companies do not have their own opinions and are often subject to too many “demand opinionsâ€. Good at design time, up, down, left and right products are all compatible, and the last one is “residual productâ€. The ic design needs to be as perfect as possible for a product and does not need to be compatible with too much.
The most interesting ic-amc7169, a ic than the yield of the ic, we design 100pcsled street lamp to use 100pcsamc7169, it is not protected ic, short-circuit voltage to reduce the current rise looks somewhat destructive! When designing a product, the first problem is how to solve it and how to avoid it, rather than setting up a lot of patches. Using this line, you have very little confidence in your own line. What else do you do? Personally think that the most deviated direction in the LED design is an ic.
The main problems that need to be solved in mains led lighting design are: how to adapt to changes in led voltage and current; mains voltage fluctuation; heat conduction and isolation safety; efficiency cost.
