Analysis of several mainstream eye protection lamps on the market
There have been more and more doubts about eye protection lamps recently. On the one hand, many parents reflect their own After using the eye protector, the child’s eyesight is declining, and the other is that the electromagnetic radiation of the eye protector is relatively large, so is the eye protector useful to our eyes? Only after we analyze the working principle and structure of the eye protection lamp on the market will we have a deep understanding of the eye protection lamp.
First of all, let’s talk about the LED eye protection lamp. LED lighting is generally characterized by no stroboscopic, high luminous rate, and it does not contain some metals that are harmful to the human body, such as mercury, etc. In theory, it can protect our eyes to a large extent, and it is more energy-saving and environmentally friendly. However, LED eye protection lamps also have their own problems. Some people say that LEDs are clean and healthy energy-saving lamps, but they are not really eye protection lamps. The color spectrum of LEDs is too narrow to be used for comparison of eye requirements. High places can only be used for general auxiliary lighting.
The current DC eye protection lamp can be described as the most advanced eye protection lamp on the market. Only the eye protection lamp lit with DC current can achieve a real flicker-free effect, and this kind of eye protection When the lamp is in use, the light emitted by the lamp is basically the same as the natural light. Although it is very bright, it will not feel dazzling at all, very soft, which can greatly relieve the fatigue of our eyesight, and the DC technology used, There is no fluctuation, avoiding electromagnetic radiation and pollution caused by high-frequency electronic ballast high-frequency oscillation.
And the most controversial is of course the high frequency eye protection lamp. Now the most eye protection lamp on the market is also this kind of high frequency fluorescent lamp. What is its working principle? It is to increase this low frequency mountain to high frequency flash, using three primary color phosphors to reduce the effect of glare, the light is very soft and not dazzling, reducing the fatigue of eyesight. But this kind of eye protection lamp is not without stroboscopic, but the frequency of stroboscopic is very high, and the human eye cannot distinguish it, so it feels the same as no stroboscopic. This is not no stroboscopic, but there is less stroboscopic, which is an illusion.
