LED lamp light source of the white light has been able to form mainly by 450 ~ 455NM wavelength of blue light to stimulate the phosphor, which the lower the wavelength the stronger the ability to attack. LED light source is usually the factory wavelength control within 500NM, usually 450 ~ 455NM or 455 ~ 460NM, are the strongest damage to the radiation section. If the wavelength of the LED lamp becomes larger, the ability to excite the phosphor is reduced and the luminous efficiency is reduced. Manufacturers in order to pursue the brightness, LED lighting will usually strengthen the intensity of light, the human eye if the long-term look at such a light source, it is inevitable that the eyes will be Blu-ray damage.
Home LED lighting as little as possible, especially LED eye protection lamp in the test period, LED is only suitable for auxiliary lighting.
German Eye specialist Professor RHWFunk (RHWFunk) study pointed out that when the "inappropriate light" continued exposure to our eyes, will cause dysfunction, especially the three primary colors, computer screen, etc. issued a large number of Regular frequency of high-energy short-wave blue light, these short-wave blue light has a very high energy, can wear
Transparent lens directly to the retina, causing photochemical damage to the retina, directly or indirectly lead to macular cell damage.
