Crystal electricity Xie Mingxun: LED rapid increase in efficiency increase oversupply worries

Xie Mingxun, deputy general manager of research and development of China's Taiwan region, said the LED application continues to flourish. This year due to China's Olympics to outdoor advertising and advertising screen LED display applications, EPISTAR has Gongfengqisheng expected, Shanghai World Expo will continue to bring another wave of LED outdoor display requirements. In addition to landscape lights, garden lights, street lights, display backlight, etc., LED application trends have also been formed. Especially in street lamp standards, there are not many qualified manufacturers, crystal electricity is one of them. However, due to the rapid progress of LED technology, with the improvement of efficiency, the number of LED use will be less and less, coupled with the blind expansion of practitioners, which is currently LED industry worries.

Xie Mingxun said that this year, the Beijing Olympic Games to drive a wide range of applications to make the market stunning LED. Crystal electric products have also been widely used in large LED billboards, water cube landscape lighting, the opening ceremony of the Olympic Games LED scroll bar, etc.. Shanghai is expected to continue to drive another wave of LED outdoor lighting demand in World Expo. In other applications, the lighting has different needs for horticultural plants, developed the LED products of different spectrum, such as spectrum in 315-400nm will influence the effect of photoperiod and plant stem growth and prevent. LED display backlight applications also expanded from LCD to the development of flexible displays.

As for LED street lighting, Xie Mingxun pointed out that, in line with the trend of energy saving and emission reduction, the mainland has recently taken the lead in the use of a large number of LED street lighting, driven by market demand. China's Taiwan area LED street lamp standard is also about to be completed. Although there are still many problems in the technical aspects, but the demand side will be moving upstream practitioners to solve the problem. At present, including OSRAM, CREE and other international manufacturers, and crystal electric and so on, the product brightness can reach the generally lamp standards, but in addition to the quality and technical problems of LED itself in the chip and the packaging process, including unstable voltage instability problems, power supply, also will affect the actual work efficiency LED.

However, Xie Mingxun believes that now the product specification and brightness, efficiency does not meet the standards of the manufacturers, clearly defined in national standards, coupled with the LED technology itself continued to progress, will continue to meet the standard may next year. In addition, although the crystal electric blue LED machine's rate dropped to 50%, four yuan LED machine's rate is less than 50%. But LED lighting and display backlight under the application of two major demand driven, will continue to stimulate the future of LED competitors substantial expansion.

On the other hand, although the LED technology progress, will accelerate the application of LED incentive, but LED technology progress at the same time, including the improvement of brightness improvement and efficiency, also will make use of a number of LED is relatively reduced, Xie Mingxun said, this is also the current existing problems of LED industry.
