Chairman of Guangdong Yayi Lighting Technology Co., Ltd. talked about LED for ten years
The company he led was one of the earliest LED application products manufacturers in China to propose the concept of LED lighting application. He has the first patent for LED lighting in China. The company he led and South China Normal University cooperated with Guangzhou Municipal Government to become Guangzhou LED Industry Research. The development base, the team he led developed the first true LCD-TV LED backlight module in China. His office is equipped with the first 42-inch LED backlight developed by the company with LED backlight core technology and Hisense. LCD TV, he is the chairman of Guangdong Yayi Lighting Technology Co., Ltd. Wu Wenfeng.
Talking about the industry
In recent years, the LED market has been somewhat confusing. A large number of inferior products were put on the market, causing people to be disappointed with LED lighting products. According to the national propaganda and guidance, people have formed high psychological expectations for the advantages of LED energy conservation, environmental protection and longevity. However, in the case that product technology, process, production and other issues have not been fully grasped and monitored, some do not Responsible manufacturers produce products with unqualified quality. As users without professional knowledge, users will only feel that this product is different from propaganda, so there is a psychological gap in the entire LED industry. This will harm the industry and is a heavy blow to LED companies that focus on brands and services.
The long life of LED applications is not guaranteed by the LED itself. The formation and emergence of LED lighting and other application products requires system technology development and rigorous process guarantee. In addition to LED light source, product protection structure, electronic components, power supply, control, process, etc. must be matched with them. There are no clear life requirements and technical standards at the link. For a simple example, if the life of an electronic device in a luminaire is 3,000 hours, even if the life of the LED itself reaches 50,000 hours, the life of the LED lamp thus produced will not exceed 3,000 hours. Therefore, the LED industry has high reliability at the same time, and the other supporting links must keep up with the requirements of LED light sources. Otherwise, it is difficult to manufacture advantageous LED application products.
The bottleneck in the development of LED application products is mainly price. In the field of lighting applications, according to the current market-based LED luminous efficiency, under the premise of ensuring energy saving of more than 50%, the ideal lighting effect can be achieved completely, but the product price is still several times or even tens higher than the traditional lighting fixtures. Times. In the field of TV backlight applications, the various technical parameters achieved by LED as a TV backlight source are far superior to CCFL (Cold Cathode Tube), but the price of LED backlight module is more than twice that of CCFL, so the price is still LED lighting. And backlight products have not yet been widely used as a threshold.
China's mainland region still faces great difficulties in making a difference in the upstream of LED. The core technology of LED upstream is in the hands of a few foreign people. Some technologies rely on craftsmanship and experience to support professionalism. It is not only based on theory and research and development. Even though Taiwan is superior to mainland China in terms of technology, it is very difficult to achieve substantial improvement and progress in the upstream extension and chip fields. Integrating domestic resources and strengthening cooperation with international brand enterprises is a more effective way out.
The LED industry is not necessarily a good thing. For some passing companies, it is an opportunity: they themselves do not expect to enter the industry, how to seek long-term development, as long as they meet the goal of making a profit, or temporarily transform into the LED industry due to other industry downturns. As a member of this industry, Guangdong Yayi Lighting still hopes that the LED industry can develop calmly, rationally and healthily in China.
