In general, the life of a led tube is more than 50,000 hours, about 10 hours per day, which can be used for about 13 years. But this is only a theoretical estimate. In fact, when using a led ceiling lamp, it is also necessary to consider the heat generated by the LED chip and the impact of the inrush current on the LED. Excessive current is still very easy to break down the diode characteristics of the LED. Then these factors will cause the led light to be damaged. When considering these principles, LED panel lamp manufacturers recommend that when using led ceiling lamps, they must learn to avoid the factors that cause the damage of led ceiling lamps.
Led light does not light up how to replace it yourself
First, turn off the switch, with the help of the folding ladder, remove the outer casing of the led ceiling light and check if the light tube is dark and dark. If so, it is very likely that the lamp has been damaged. Must be replaced, this LED tube can be bought in the hardware store, it is recommended to choose a well-known brand.
Secondly, if the lamp is still intact, you should try to tighten the lamp joint to see if there is a bad contact. This is also a relatively simple operation and is easy to happen.
Then, if none of the above problems occur, you can check whether the ballast is intact, whether it has a burning smell, whether the ballast has a black burnt appearance, and if so, the possibility It is the problem of the ballast. It is better to replace one, the price of the ballast is more expensive than the lamp.
Finally, check the contact of the led light for power. If not, it should be a switch or line problem.
According to the above operation, basically, the line is checked from the lamp head to basically find the cause of the defect. At the same time, we should also pay attention not to rush to open the LED ceiling lamp, which will generate inrush current, affect the service life, and also keep the air circulation of the room, to avoid the humidity of the room is too heavy.
