Most of the people who buy lamps will pay attention to the safety of their leakage, but another kind of safety - "photobiosafety" is actually worthy of attention. From the experts responsible for photoelectric inspection, it is known that the "photobiosafety" detection of unqualified lamps may cause injury to people and may also hurt people's eyes. In particular, LED lamps that use blue or ultraviolet light are more prone to the problem of leakage of blue light or ultraviolet light. At present, the EU has mandated LED lights for photobiosafety testing, and experts have called for domestic attention.
"Photobiosafety" can be understood as "optical radiation". In the spectrum emitted by some light sources or lamps, in addition to visible light, there are ultraviolet light and infrared light, which will produce different degrees of photochemical UV damage to human eyes and skin. And infrared radiation (heat) hazards. If the process of the luminescent material is not closed, ultraviolet light or blue light will be transmitted, which will cause harm to the skin and retina of the human body. Experts suggest that because there is no mandatory inspection in China, only large brands of products can be purchased.
Jiang Zhongyu, an engineer at the Institute of Life Medicine and Optics at the Metrology Institute of Guangzhou, said that it is necessary to see whether the lamps will cause damage to the eyes. It is not easy to judge from the "shaking eyes". "At present, when consumers buy lamps, they tend to consider aesthetics and Brightness, but not aware of the photobiosafety of the luminaire."
Jiang Zhongyu said that in recent years, there are more and more LED lamp products, but only the export products are used for photobiosafety testing. There are almost no domestic products. "This is because the country has not yet included the scope of compulsory inspection. We also appeal to everyone to pay attention to this. According to him, about 10% of the products submitted for inspection will reach the "high risk" level, which means that it will cause harm to the human eye.
