Lights, then, what if the led ceiling light does not light up? What is the reason for the led ceiling light not shining? The following Huadian breeze will give you a explanation for your reference.

If the led ceiling light is only the outer lampshade is broken or dropped, in the case of cutting off the power supply, remove the lamp cover and re-select a suitable size of the lampshade on the market.

If the Led ceiling light is not lit, the cause should be checked step by step.

1. The switch is turned on. Test with the test pencil at the led interface. If one has electricity and the other has no power, the power supply is normal and the LED power supply is bad. If both of them have electricity, the power supply circuit is abnormal, and the switch may be broken or the line may be faulty.

2. If there is no problem with the power supply circuit, turn off the power switch, board the folding ladder, remove the outer casing of the Led ceiling lamp, and check if the lamp is dark and dark. If so, it is very likely that the lamp has been damaged. Must be replaced, Led ceiling lamp tube can be bought in the hardware store, it is recommended to choose a well-known brand.

3. If the lamp is still intact, you should try to tighten the lamp joint to see if there is a bad contact. This is a relatively simple operation, but it is easy to happen.

4. If none of the above problems occur, check whether the ballast is intact, whether it has a burning smell, and whether the ballast has a black burnt appearance. If there is, then a big possibility is the problem of the ballast. Just replace one, and the price of the ballast is more expensive than the lamp.

5. There is also a case where, in addition to the power supply, the lamp does not turn black from the appearance, it is necessary to check the positive and negative pins of the led bulb to see if the Led ceiling lamp is operating correctly. The connection, if there is an incorrect operation, causes the bulb to not light, then re-welding the led bulb can generally be solved.

Note on the use of Led ceiling lamps:

When using LED ceiling lamps, try not to switch frequently. Because the LED ceiling lamps are more frequently activated, the current through the filaments is greater than the current during normal operation, so that the filament temperature rises sharply and accelerates sublimation, resulting in inrush current, which will greatly Reduce the service life of LED ceiling lamps, so try to minimize the number of LED ceiling lamps. At the same time, keep the air circulation in the room and avoid the humidity in the room.

Although in theory, Led ceiling lamps have a service life of more than ten years, but the quality of many Led ceiling lamps on the market is not reliable, so when the Led ceiling lamp is broken in a certain period of time, Will appear. Generally speaking, the main reason for the damage of the Led ceiling lamp is the lamp and the ballast. Just buy the same model and replace it.

The above is the reason why some of the LED lights that Huadian Breeze told everyone to analyze are not bright, I hope to help everyone.
