Talk about the hazards of LED blue light

In recent years, there has been a lot of discussion about the 'LED blue light hazard' in the society. In fact, the blue light hazard of LED lights does exist, and this problem has been added to the 'National Compulsory CCC Certification' to detect LED blue light hazards. The blue light hazard of LED lights is mainly related to the quality control of many LED light manufacturers. Because the white light LED is made of LED blue light chip with yellow light phosphor, it can be seen from its spectrum chart that there is a peak in the spectral energy just in the blue band, and it is relatively high. Blue light is the main cause of myopia! That's why people pay special attention to the 'LED blue light hazard'. In fact, the lighting sources in nature, including sunlight, contain blue light to varying degrees, but if the blue light is controlled within a certain range, it will not cause damage to human eyes. Therefore, as long as it is a fluorescent lamp, the light emitted by all lamps contains blue light. It can be said that we cannot do without blue light, but it is even more dangerous to ignore the blue off hazard. In all lighting sources, the spectrum of LEDs should be precisely adjustable. For example, designers can greatly reduce the proportion of LED blue light by selecting high-quality chips, supplementing light, increasing color rendering index, etc., so that the LED lighting can be manufactured. The light source is relatively safe, but with the rapid expansion of the LED lamp market, some manufacturers with poor or no technical strength ignore or ignore the problem of the blue light hazard of LEDs, and only take goods from the supplier to assemble the LED lights, so this It also caused the uneven quality of LED lights on the market, and there were more blue-light hazards of LED lights. Therefore, in theory, among all types of table lamps, LED blue light is harmful to children's health, not only refers to eye damage, but also exists. As for the LED eye protection lamp, it is a gimmick, but it reduces the flicker. Of course, if you want to use an LED table lamp, you must use a qualified LED table lamp produced by a regular brand manufacturer, and has passed the domestic CCC or foreign UL, CE and other safety certifications and electrical certifications. If you use fake and shoddy LED desk lamps, it is really better not to use them!
