With the development of led technology becoming more and more mature, lighting products using LED technology have now begun to occupy the majority of the lighting market. Eye protection lamps are still very important for students, because students have heavy homework, a good eye protection lamp can protect our fragile glasses. Now LED eye lights are the rising star in the eye light industry, especially individual controlled led strip.
So, are LED eye protection lights really good? Xiaobian this for you to explore.
The advantages of LED eye protection lamps
The first thing to say is that there is no strobe. Stroboscopic is very important for an eye protection lamp. The faster the stroboscopic, the more uncomfortable the human eye feels. In contrast, the slower the stroboscopic, the more comfortable the human eye feels, which can effectively reduce visual fatigue. Because the traditional eye protection lamp is basically an AC power supply, so can not do strobo-free. And LED eye protection lamps because of the use of DC power supply, so can do no stroboscopic. However, we should know that LED eye protection lights with a bad driver can strobe even faster than incandescent bulbs.
The second advantage is the LED eye protection lamp. in the same power, LED eye protection lamp is brighter than ordinary fluorescent lamp bright on many, so it has the advantages of energy saving and environmental protection.
The third advantage is that the service life of the LED eye protection lamp is relatively long, which is basically better than all the traditional lights.
Disadvantages of LED eye protection lights
The biggest drawback of LED eye protection is its blue light. When it comes to blue light, let us first introduce the luminous mechanism of LED eye protection lamp. There is a problem with the spectrum of leads, which has much more blue light than red and green. Controlled by a chip, the LED lights emit blue light, and then the yellow phosphor is excited by the blue light, which neutralizes the two, resulting in white light. Blue light is a kind of light that does great harm to human eyes. General civil LED eye protection lamps have the problem of blue light spillover. Only the top RGB three-color LED can solve this problem, so as to achieve the same spectral level as the three-color fluorescent lamp tube. However, this LED has a high price, large calorific value and relatively high cost, so it will not be used in civil LED basically.
From the above introduction, we can see that the LED eye lamp is not as good as advertised, blue light overflow is always a problem that it can not avoid, unless it is the top RGB-LED.
