What is the reason why the LED eye protection classroom lights are not bright after a long time
The good eye protection classroom lights will directly affect the eyesight of the students. Some schools will respond that the classroom lights will not be bright enough after a long time. In fact, this is not a quality problem. When these problems occur, you should start to check the eye protection. The classroom lights are out, so deal with them in time. Then again, what is the reason why the light is not bright enough? Let's take a look!
1. The eye protection classroom lights will dim if they are used for a long time
Once the lighting lamp with the best quality is used for a long time, the loss of many parts will become greater and greater, so the lighting effect provided will be reduced.
2. Insufficient current will also reduce the lighting effect of eye-protecting classroom lights
Once the power supply voltage is unstable, it will also cause the lights to dim. In addition, the voltage change of the power grid will also affect the brightness of the lighting lamp. For example, at night, when the electricity consumption peaks, the load on the power grid is relatively high. At this time, the current passing through the wires is relatively large. Then, according to Ohm's law, U=IR, the voltage consumed by this wire is relatively large, so the voltage of the electrical equipment assigned to the lighting lamp will also decrease, resulting in dimming.
3. Excessive accumulation of dust affects the lighting effect of the eye protection classroom lamp
As the lighting lamp is used for a long time, the dust will accumulate more and more over time, which will cover and affect the lighting effect of the lighting lamp, causing the light to spread weakly after passing through the dust, which leads to the phenomenon of insufficient brightness.
So when you find that the brightness of the eye protection classroom lamp is not enough, see if it is caused by the thick dust. If the brightness is not enough due to the dust, you can clean it to restore the brightness of the lamp. However, if it is caused by the aging of internal parts, the editor recommends to replace them in time to avoid excessive wear and tear and damage to the lighting.
