Peng Wanhua: LED needs to find breakthrough points from technological innovation







Secretary General of Optoelectronic Devices Branch of China Optical Optoelectronics Industry Association

Currently in the LED industry, brightness is one of the most important indicators to measure the performance of LEDs. I propose the following suggestions for the development of the LED industry.


First of all, the development of electronic information products generally depends on several major stages, namely: basic research results, product research and development production, product application research and development, application products, market expansion, etc. The size of the industry formed by the series of products ultimately depends on the market. Size, the LED industry is no exception.


Secondly, the LED industry is still very small from the current point of view. There are only three reasons for the market of only a few tens of billions of yuan. First, there is still a breakthrough in LED technology. In particular, the current industrialization level of luminous efficiency is generally 60 lm/ W ~ 80lm / W. According to foreign reports, this year, a small number of 100lm/W LED products can be provided. Compared with the energy-saving lamps 70lm/W~80lm/W, this indicator should be upgraded to 150lm/W~200lm/W. In addition, the requirements of the main parameters of LEDs for general lighting have not been clarified, such as color temperature, color rendering, safety and so on. Second, the cost of LED lighting products is too high, several times that of ordinary lighting, and some are ten times. Third, the field of LED product application is currently in the stage of development and expansion, and has not yet formed a large-scale market, which needs further development and expansion.


The potential market for LED products is very large, with a market share of several hundred billion yuan. To achieve such an industry scale, it is necessary to innovate from LED technology, find breakthrough points, and adopt mass production of new technologies and processes. Reduce LED costs, accelerate the development of LED product applications and expand the market scale, starting from these three aspects, the LED industry will become bigger and stronger.
