Eye injury failed LED lantern
Experts Call for LED lights should be "light bio-security" force detection
"Optical bio-security" can be understood as "optical radiation", issued in a number of light source or light spectrum, in addition to visible light, there are ultraviolet and infrared light to the human eye and the skin will produce different levels of photochemical UV damage and infrared radiation (heat) damage. If light-emitting materials technology, however, UV light or blue light will be transmitted out of the skin and retina of the human body harm.
Experts suggest that because the country does not compel inspection, can only try to buy big brand products.
(Reporter He Yingsi correspondent Sui Zixuan) we will focus most of their buying lamps leakage security, but another security - "Light of biological security" in fact, also deserves attention. Yesterday, the reporter responsible for optical inspection of experts from the Department learned that "light bio-security" test failed lamps may people according to injury, also may hurt the eyes. Particularly the use of Blu-ray or ultraviolet light of the LED lights, more likely to leak Blu-ray or ultraviolet cause injury issues. The European Union has mandated the current LED lamps light of biological safety testing, the expert should be called national attention.
Measurement Institute, Guangzhou Institute of Biomedicine and optical engineers in the Jiao Jiang told reporters, lamp will depend on the eye injury, not simply from whether the "blink of an eye" to judge, "now consumers lamps often considered is beautiful and brightness, but the light of biological safety lamps are not aware of. "
Jiao Jiang said in recent years, more and more LED lighting products, but the biological safety testing by light only export products, domestic products have little, "This is because countries have not yet included in the scope of mandatory testing, we also call that we should attach importance to this Detection. "According to him, in the submission of products, the percentage of products will reach about a" high risk "level, that will produce damage to the eyes.
