Because the LED industry has been rapid development in recent years, has graduallyfrom the government to the civil lighting lighting direction, due to the recent introduction of national series of encouraging the development of LED industry's policy, but it also brought a lot of problems, the LED driving power supply problems will be exposed to. LED driver power supply market and the downstream industry,especially closely related to the development of high power LED street lamp, but with the LED performance parameters of continuous improvement, LED lighting marketgradually rise, applications more widely, especially in 2011, the industry look fromoutdoor to indoor commercial lighting at the same time, the LED drive power isdifferent needs.
Fault LED lamp although most occur in power, but can not blindly blame power supplyenterprises. This also shows that the reliability of LED power supply, application fieldand also closely related to the. Application of LED products will gradually from thegovernment engineering oriented to domestic lighting leading, the application of LEDwill gradually subdivision. Although, known as the single LED life up to 100000 hours of argument has been blasting, but the LED driver does not keep pace with the actuallife of the LED. According to focus light technology Taiwan Donglin group (HEP)chairman Hong Dasheng, LED driving power supply has dozens of components, eacha small part as long as the problem will affect the whole electric drive, then affect the whole life of lamps and lanterns. At present, some good LED driver life can reach 2-3million hours, HEP has been able to achieve, and now HEP has in the experimental phase modulation of 50000 hours of LED driving power supply with the prolongation of LED throughout the service life of the lamp, is expected to be mature productlaunch within the next three years.
So for the LED power supply enterprises, in order to reduce the power failure, in addition to full interaction and trades people, how to make better use of their own advantages, intensive and meticulous farming, play in the segments of the role, also in 2012 the next question worthy of careful planning. In the four municipalities directly under the central government, lighting technology forum recently held in Tianjin,Shanghai Lighting Association vice chairman, Fudan University Institute of electric light professor Liu Muqing also stressed, LED should be compatible products,interchangeable in functional lighting application, realize the modular, standardization and standardization. Do not need to pay attention to any complexity of solid state lighting brings, easy to use products will obviously be more welcomed by users, and the module and intelligent will give users a lot of convenience, is a trend in the futureof LED lighting system. With the development of technology and the maturity of the market, industry standard be imperative, mature and perfect standard is the basicguarantee for the healthy development of LED industry, modular product andconstant voltage constant current integration will become the mainstream, the productwill also gradually increase the intelligent control function.
