People can only choose a desk lamp when they are reading and writing, and a desk lamp is an essential lighting tool in modern homes. It mainly focuses light on a small area to facilitate work and study. According to statistics, the average Chinese student spends 2-3 hours a day under a desk lamp, and the distance between the brain and the lamp is only 30 to 40 cm, while the World Health Organization test reports that the radiation value of high-frequency eye-protection lamps is 40UT to 400UT.

For portable luminaires and hand lamps, if the blue light hazard level measured at a distance of 200 mm exceeds RG1, the symbol "Do not stare at the light source" should be clearly marked on the outside of the luminaire, as shown below. Also, the sign should be positioned so that the user cannot see the light source while seeing the sign. According to the above requirements, companies should not mark the symbol on the mounting surface or luminous surface of, for example, LED desk lamps.

The future of LED depends on these technologies
2022-09-27
Developing color conversion materials with high flexibility, stability, and light efficiency that do not contain rare earth elements has been a research topic in this field. In recent years, there have been products using ultra-thin OLED panels to make flexible lights and displays on the market. However, up to now, these products still have problems with poor reliability and high driving current. In response to these issues, researchers have conducted relevant research and significantly improved the light efficiency, reliability, and color tunability of quantum dots.
