The principle of eye protection lamp
Recently my cat dad asked to buy eye protection lamp for my “kitten”. Found this stuff really varied. After reading the Encyclopedia eye protection lamp entry carefully, I concluded these points:
1) The basic working principle of the eye protection lamp is to increase the low frequency flash to the high frequency flash, and the flashing speed exceeds that of the human eye. The speed of neural response, so people will feel more comfortable in the eyes when studying and working under this kind of light.
2) Ordinary incandescent lamps are actually an eye protection lamp. Because the alternating current heats the filament first, the filament heats up, and then emits light. Because the filament has a heat capacity, the filament is still hot when the power supply changes, and the light and dark changes will not be as intense as fluorescent lamps (fluorescent lamps).
3) When purchasing eye protection lamps, pay attention to the CCC, “3C” of the national security compulsory certification.
4) Eye protection lamps cannot adjust the brightness of the light, and all eye protection lamps that can adjust the brightness have no eye protection function.
5) Eye protection lamps have stroboscopic radiation hazards, which are more than 100 times that of mobile phones, computers and other radiation products, and “light pollution”
It is very dizzying to see , isn’t this a contradiction? Since this is the case, do you still need to use eye protection lamps, is it safer to use incandescent lamps? I hope everyone can discuss this issue clearly and recommend some good brands and models.
