Zhang Jiaxian: LED backlight and LED lighting device development trend

How much is the demand for MOCVD? In 2015, whether domestic MOCVD has the possibility of mass production, what kind of impact will it be caused by Taiwan-funded LED enterprises to enter the mainland, what is the situation of China's LED industry in the upper, middle and lower reaches, and what is the cost of LED lamps? Control, you will find the answer to the question at the closing ceremony of the 2010 LED Illumination China Tour and the 7th LED Industry Theme Summit held at the Shenzhen Golden Central Hotel on October 13th.

The conference attracted the general managers of nearly 200 well-known companies, CREE Vice President and General Manager of China, Shi Gancan, Philips Lumileds Asia Pacific Sales Vice President Alvin Tse (Xie Wenfeng), and Zhongjing Kechuang Optoelectronics Technology Co., Ltd. Dong Zhijiang, General Manager of Wuhan Diyuan Optoelectronics Technology Co., Ltd., Nie Pengxiang, CEO of Yanlei Technology, He Wenming, Chairman of Zhongke Wanbang Optoelectronics Co., Ltd., Lin Xiaoning, Deputy General Manager of Jingke Electronics (Guangzhou) Co., Ltd., R&D Director of Ruifeng Optoelectronics Co., Ltd. Zhang Jiaxian and Zhang Hong, senior manager of electrical appliances of CTI China Testing Technology Co., Ltd., visited the site and gave a keynote speech.

Dr. Zhang Xiaofei, CEO of Gaogong LED, gave a speech on the opening ceremony of the 7th LED Industry Theme Summit Forum and made a profound analysis report on the upper, middle and lower reaches. On behalf of the high-tech LED team, Zhang Xiaofei presented a thank-you commemorative card to the 2010 LED illuminating China Travel Support Unit. Zheng Liyao, deputy director of the High-tech LED Industry Research Institute, announced the LED illuminating the candidate list for China's annual selection campaign.

Zhang Jiaxian: LED backlight and LED lighting device development trend

Zhang Jiaxian, R&D Director of Ruifeng Optoelectronics Co., Ltd. introduced the development trend of LED backlight and LED lighting devices. He pointed out that the improvement required for LED TV applications is: the solution of metamerism, the solution of heat dissipation, the improvement of light efficiency, and the optical design. And the improvement of light guiding materials, and the development trend of LED TV will be the reduction of the number of LEDs, and the corresponding single use power is increased; higher requirements are placed on LED devices and system heat dissipation; light guiding efficiency of light guide plates is improved; LED The increase in light efficiency has led to a rapid reduction in the cost of TV BACKLIGHT; the high power and modularization of LEDs have become a trend; the LED TV price war will break out in 2011~2012; the bottom backlight technology will eventually become inevitable; the fiber optic light guiding technology will become a solution for TED. One of the TV cost and color schemes.

Zhang Jiaxian proposed that the bottleneck of LED packaging in lighting is the improvement of light efficiency, the solution of heat dissipation, the distribution of phosphors, the development of high-reliability materials, high-power single-chip or multi-chip integration, cost, etc. The solution.

Our Led Flood Light is energy saving,led based,wash fixture,incorporating high power LEDs. LED color is available in RGB color changing,or single color. Our products are supplied with a low current and thereby generate long-lasting light.Other manufacturers supply LEDs with a maximum current,to generate the required brightness with less LED chips,however,has negative effects on the longevity of every single LED.Our products are manufactured with more LED chips.And the housing is composed of die-casting aluminum fixture,good at resistance against oxidation,making the housing durable,exquisite and graceful,waterproof well,. Constant current driving ensure the stable and reliable performance. Adjustable beam angle to fulfill your satisfactory effect. Led flood light is widely applied in building facade,stadium,flyover,monument,park and parterre,to render the atmosphere,increasing the visual effect.
