"China Electronics News" made recommendations on how to promote the development of China's LED lighting industry in a healthy and benign manner, and interviewed General Manager Li Mantie of Shenzhen Lehman Optoelectronics Technology Co., Ltd.
   Regarding the objective analysis to grasp the key issues of LED lighting development, General Manager Li Mantie said that the “Ten Cities and Ten Thousands†main streetlights are not suitable from the high-risk entry point of outdoor lighting, involving lumen efficiency, heat dissipation problems, and optics. Problems, life issues, all need to be improved. Since chip devices account for 50% of the total cost, large-size chips or devices used for street lamps are monopolized by foreign brands. The domestic epitaxial chip and packaging industry has limited benefits in the “Ten Cities and Ten Thousand Cities†project.
   Regarding the development of technology to be market-oriented, General Manager Li Mantie stressed that LED research and development should be strongly encouraged. The gap between China's LED level and foreign countries, one in the brand, two in the R & D investment. Foreign giants have gained a lot of profits due to the high added value of the brand, and they have the strength to invest heavily in research and development. China's LED companies are still in the stage of entrepreneurial development, and the profit situation is not very good. The funds and manpower that are independently invested in research and development are not enough. If the government can increase R&D investment support for outstanding enterprises in the domestic LED industry, it will be of strategic significance to the development of China's LED industry.
   Regarding the gradual development of the LED lighting industry, General Manager Li Mantie’s view is that the low-power LED devices used in LED indoor lighting have matured and 90% can be localized. The development of LED indoor lighting will drive the rapid development of China's LED industry chain. It will benefit Chinese local LED companies that are currently in the period of entrepreneurial development and have good strategic significance. For example, LED fluorescent lamps have reached the eve of commercial promotion, because their prices are falling faster, technology is becoming more mature, energy saving effects are obvious (saving 60%), 90% can be localized, products can be standardized, and the number of uses is huge. Therefore, national policy Levels can be promoted and promoted. At present, a T8 LED fluorescent lamp, if the application is illuminated within 24 hours, the cost of the initial multi-input can be recovered within one and a half years by the power saving fee, and has other advantages such as long life and no stroboscopic. This payback period will be further shortened as technology advances and prices adjust.
