During the 7th China International Semiconductor Lighting Exhibition and Forum, He Wenming, Chairman of Zhongke Wanbang Optoelectronics Co., Ltd., accepted the interview. In the interview, Chairman He Wenming published many unique insights from the technical route of LED to the market trend of LED.
Innovative MCOB multi-cup module packaging technology reduces costs
He Wenming, Chairman of Zhongke Wanbang Optoelectronics Co., Ltd. introduced that under the guidance of relevant government policies, under the strong support of the technical institute of the Chinese Academy of Sciences, Zhongke Wanbang has developed rapidly. In particular, the MCOB multi-cup packaging technology provided by the Chinese Academy of Sciences, this technology is better in the packaging industry, which can greatly improve the light efficiency, greatly reduce the cost, and the product stability is also quite high. Because this technology has a unique solution in terms of heat dissipation.
He Wenming believes that the most fundamental reason for the high cost of LED lamps is not the chip, but the packaging. The MCOB packaging technology, initiated by Fujian Zhongke Wanbang Optoelectronics Co., Ltd., can improve the light efficiency by 20-40%, effectively solve the heat dissipation and reduce the overall cost by 30-40%.

He Dong also detailed how MCOB packaging technology can improve light efficiency, solve heat dissipation and control costs. He Dong believes that MCOB technology will become the mainstream of LED packaging industry in the future.
MCOB technology is a module packaging technology that can improve the reflectivity of the holder cup and improve the light extraction efficiency. The MCOB technology also allows the substrate to be in direct contact with the chip, and the heat of the chip can be directly transmitted to the substrate, and the thermal conduction speed is relatively fast. This can solve the problem of chip heat dissipation very well. If mass production, the cost can be greatly reduced, He Dong said that the price of LED lights can be as low as ordinary energy-saving lamps in the future, so that ordinary families can accept. He Dong revealed that the cost of LED bulbs of Zhongke Wanbang can be controlled within 8 yuan/100LM at this stage.
There is no market without standards
When He Dong talked about the LED industry standard in the interview, he said that there is no market without a unified standard, and he calls for the introduction of national standards as soon as possible. Since the standard cannot be introduced in time, the market is not standardized. In particular, domestic enterprises have now taken into account the cost factor and relaxed the quality control, resulting in uneven quality of LED lighting products on the market, and even shoddy situations. This will reduce the image of LED lighting products in the minds of consumers and increase the difficulty of promotion.
The luminous efficacy of Wanbang LED lamps has achieved 120 LM/W
After the interview, OFweek Semiconductor Lighting Network also specially visited the exhibition area of ​​Zhongke Wanbang. The booth was crowded with people. The cost-effective products of Zhongke Wanbang attracted many eyeballs, and many customers came here.
