LED lamps, buy, look for signs, don't be cheap

Whether in study, work or life, desk lamps are our good helpers. With the improvement of LED technology and the decrease of price, LED also has a place to use on desk lamps. Although the luminous efficiency of LED is higher than that of traditional lighting products, consumers cannot purchase LED lamps at will. Some medical experts pointed out that many LED lamps have serious blue light overflow problems, which can cause irreversible damage to children's retina. There are also electric light source experts who suggest that the current national recommended standards should be changed to mandatory, and government departments are recommended to carry out special risk monitoring for indoor LED lighting products. Yu Anqi, deputy director of the Shanghai Center for quality supervision and inspection of national electric light sources, said that blue light, as a kind of colored light, is commonly found in various lamps and lanterns, which is inevitable. At present, most LED lamps and lanterns are on the market, it is through the blue light emitted by the chip to excite the yellow fluorescent powder to adjust to white light. Once the control is not good, the problem is particularly prominent. Technicians in the electric light source industry pointed out that excessive blue light for indoor lighting will have a series of effects on human physiology, psychology and optic nerve. At present, there has been spraying luminous diffusion lampshade technology, which is used for secondary packaging of LED lamps and has lower light biological safety index than traditional LED lamps. Deng Yaqin, the head of the technology and chairman of Shanghai Xiangling Optoelectronics Technology Development Co. , Ltd. , said that their export products were only 1/5 of the standard in the EU test. However, Yu Anqi reminded that LED lamps are not suitable for use as student desk lamps. It is better to use incandescent lamps. Yu Anqi believes that blue light is dangerous to people's health. He suggests that the current national recommended standard should be changed to mandatory and included in the CCC standard for lighting grade, it is suggested that government departments should carry out special risk monitoring for indoor LED lighting products. Of course, consumers should not simply consider the price issue for the sake of being cheap when purchasing lighting products. Good quality is also an indispensable and important factor for lighting products, we also remind users to choose products with brand and quality assurance so as to obtain a good lighting experience.
