China has become the world's largest producer of LED lighting, according to the Ministry of Science of the 12th Five Year Plan in 2015, LED lighting market share should reach to 30%, the National Development and Reform Commission has also developed a roadmap to completely phase out incandescent in 2016. This is one stimulant for the LED industry, with incomplete statistics, the country's LED industry park to build no less than 20, the total LED Torch size of the industry in 2013 is expected to reach 200 billion. In 2015, it will exceed 500 billion. However, just when the industry to share the feast triumph, the medical community has expressed concern, vice president of the Chinese Society of ophthalmologists (Shanghai ENT Hospital) Professor Sun Xinghuai said that according to international research results, the blue LED emits a long-term effect on the human eye, it can cause serious injury. "Blue-ray will damage the retina, the specific location is the photoreceptor, it receives light which is converted into an electric signal of visual cells, it accumulates in front of you to a certain amount of light cannot feel it, then it blind .

Blue light, as a shade of color light, exists in a variety of lamps. REMEDIES that most LED lamps on the market, was sent by the chip blue, yellow phosphors excited to reconcile into a white light, and therefore, LED blue light problem is particularly prominent. French Essilor He Yi, president of the China Investment Corporation, said the LED Flashlight international eyewear industry has been paying close attention to this issue. But worrying is that the vast majority of domestic consumers still completely unaware.
"Children myopia is very fast, it is saying (blue hazard) if there is a certain relationship, we are now working on, find a way to filter out blue light."Precision of the LED constant current driver is important for LED light fixtures manufacturers. For the LED car light precision constant current of LED driver IC is will have some discrete during the production. When LED lighting manufacturers product and commission the LEDs, the same power, the same LED light load, the same constant current source power supply board will be has different constant current because of the different drivers for the same type of personality differences, so that the same LED light load luminescence brightness is different, and this will increase the constant current source power supply board high-volume production line debugging time, affecting productivity. Thus, the constant current source power supply board manufacturers should LED Ceiling Light use high precision constant current driver IC, current precision should be at least less than ± 3%, ± 1% is better case, but its price will be higher than ± 3% product.
