LED lamps have serious Blue ray overflowFor energy-saving products, the concern of the whole society is more than ever before. LED which is called fourth-generation light source has realized explosive growth under the double promotion of industrial capital and government subsidies in recent years. Recently, some medical and electric light experts pointed out that many LED light fixtures have serious blue ray overflow, the retina of the human eye will suffer irreversible harm over time, seriously even leads to blindness. LED blue light problem is particularly prominent It is understood that the blue ray is ubiquitous in a variety of lamps as a chromatic light. Sun Xinghuai, Professor in Shanghai ENT Hospital said, most LED lamps on the market emits blue light through the chip, stimulate the yellow phosphors to reconcile into white light. Therefore, LED blue light problem is particularly prominent. Measures to overcome LED blue light overflow Dr. Yang Weiqiao, the deputy director of the national semiconductor lighting application systems engineering technology research center, said, there is no direct scientific evidence for the saying that blue ray injury eyes. Dr. Zhang Shanduan, deputy director of Lighting Research Institute of Fudan University said that a recent example for blue ray injury is the blue ray of bath lights cause the eyes of an infant to be burnt, eventually leading to blindness. He identified national standards named "Bio-security of lamps and lamp systems", there is a chapter dedicated to express High Power LED blue ray hazards and quantify the calculation method, he said it was regrettable that this is only recommended standard, which has no mandatory function for manufacturers. At present, there is almost no threshold to enter the LED industry, especially among the downstream assembly fixtures manufacturers, there are a lot of family stores model workshops, not to mention the quality of management and control system. Industry now fierce controversy whether it needs to force safety testing LED lamps for LED blue light overflow. Dr. Zhang Shanduan thinks that this problem is not impossible to overcome. The development of low color temperature product, to strengthen secondary light distribution can significantly reduce the hazards. He said that the imperative now is to do two things. First, the state must develop mandatory standards as soon as possible; secondly, organize experts to give use recommendation.www.ledlightmx.com is a high-tech lighting enterprise deal in develop, produce and sales.
