Are led lamps good for eyes
Three primary colors than ordinary fluorescent eye, depends on two things: one is stroboscopic rate in the scope of the human eye is suitable for vision not eyes acid bilges feeling after for a long time; Second, the PGB tricolor high color rendering index, close to the sunlight. LED lights, the use of automatic constant current power supply, dc way, there is no flashing, so it is better than fluorescent lights. But color rendering index below trichromatic lamp, between 60-85, the three primary colors is 92
Personal think the LED desk lamp is best not to give the child to use, see an article on the net, with parents bought a philips LED desk lamp, results open instruction at home which is not suitable for children use. But on the outer packing the desk lamp that shield an eye, we ordinary people don't understand adept, personal understanding the desk lamp that shield an eye, of course, is to protect everyone's eyes, don't include a child? Written by some big brands are so visible, small brands figure by interests, of course not written in the book of the manual. In order to children's eyes, or do not use good, it is better to buy a few pieces of bulb lamp for a baby.
Your problem, want to answer, the real LED lamp (from the luminous efficacy and color rendering index, dazzle light, intensity of illumination and light Angle to identify) is good for your eyes.
Second, from the Angle of the optical to see: Traditional light source, and at the same time issued a red wavelengths of light, you can understand as invisible infrared, the over 780 - nm wavelength radiation can cause damage to the eyes, myopia are mostly indoors for a long time, too much rely on under the traditional lighting light caused by the work and study. And LED light source, mainly is the blue chip inspire yellow phosphor, the wavelength of light in between 380-780 nm, no ultraviolet and infrared light, good LED light source (note is good, you usually see in stores outside does not conform to the mostly, the current domestic exports have all the good) color rendering index greater than 85 (color rendering index, the higher the more close to natural light), have relatively full spectrum, and also is to have the green light at the same time, close to natural light, when you know a lot of treatment of myopia are to see green things, because it is depends on the green light to repair damage to the eyes, at least not add to myopia.
A, from the perspective of electronic appliances to see: LED desk lamp, due to the light source is LED, LED is a dc light-emitting devices, theoretically to the light, the previous generations of light source with us to the light, the traditional light source such as energy-saving lamps, metal halide lamp, incandescent lamp is communication, will follow the frequency of the input current civil power grid, to change, our country is 220 v, 50 hz) of power grid, so the frequency of communication wave makes the traditional light source will appear in the stroboscope, long-term study working in this kind of light source under the eyes hurt. Use LED lamp, want to see you understand not understand, not all LED lamps are no stroboscopic, if is to use the desk lamp of rechargeable batteries, light-emitting panel does not directly see each LED lamp bead, no dazzle light is that it can until the protection for your eyes, please note that must choose surface is illuminated. Another is to use constant current power supply drive LED desk lamp, this product, you don't understand, or to find a reputable manufacturer to buy.
