Whether it's studying or working, a desk lamp is an essential companion. With the advancement of LED technology and the drop in prices, LED lamps have become more popular in homes and offices.
Although LEDs are more energy-efficient than traditional lighting, not all LED lamps are safe for everyday use. Some medical experts have raised concerns about excessive blue light emissions from many LED products, which can cause long-term damage to children’s eyesight. Experts in the lighting industry also suggest that current national standards should be upgraded to mandatory regulations and that government agencies should conduct stricter monitoring of indoor LED lighting products.
Yu Anqi, deputy director of the National Center for Quality Supervision and Inspection of Electric Light Sources, explained that blue light is naturally present in many types of lighting. Most LED lamps produce white light by using blue chips to excite yellow phosphors. However, if the balance isn't properly controlled, it can lead to harmful blue light exposure.
When purchasing lamps, always choose certified and safe products.
Industry professionals warn that prolonged exposure to high levels of blue light can affect human health, including vision and psychological well-being. A new diffuser technology has been developed to reduce blue light emissions, making LED lamps safer than before. Deng Yaqin, chairman of Shanghai Xiangling Optoelectronics Technology Development Co., Ltd., mentioned that their products meet EU safety standards, with blue light levels only one-fifth of the limit. However, Yu Anqi still advises against using LED lamps as desk lights for students, suggesting incandescent lamps are a better choice.
Yu Anqi emphasizes that blue light poses real health risks and recommends that the national standard should be made mandatory and included in the CCC certification process. He also calls for targeted risk assessments of indoor LED lighting products.
Consumers shouldn’t just go for the cheapest options. Quality matters. Choosing reputable brands ensures better performance and safety. Investing in reliable lighting not only improves your environment but also protects your health in the long run.
