Whether it is studying or working, the desk lamp is our good helper. With the improvement of LED technology and the reduction of price, LED has also been used in desk lamps.
Although the efficacy of LEDs is higher than that of traditional lighting products, consumers are not free to purchase LED lamps. 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 experts in electric light source suggesting that the current national recommended standards should be changed to mandatory, and it is recommended that government departments carry out special risk monitoring for indoor LED lighting products.
Yu Anqi, deputy director of the National Center for Quality Supervision and Inspection of Electric Light Sources, said that blue light is a kind of color light, which is common in various lamps. This is inevitable. At present, most LED lamps on the market emit blue light through the chip to stimulate yellow fluorescence. Powder to reconcile into white light, especially if the control is not good.

At present, there is a sprayed illuminating diffuser technology for secondary packaging of LED lamps, which is lower than the bio-safety index of traditional LED lamps. The head of the technology, Deng Yaqin, chairman of Shanghai Xiangling Optoelectronics Technology Development Co., Ltd., said that their export products in the EU test, the blue light overflow value is only one-fifth of the standard. But Yu Anqi reminded that LED lamps are not suitable for use as student desk lamps, the best is still incandescent lamps.
Yu Anqi believes that the danger of blue light is related to people's health.
