How to avoid damage to led ceiling lights?
Generally speaking, the service life of LED lamps is more than 50,000 hours, and the lighting time is about 10 hours a day, that is, it can be used for about 13 years. But this is only a theoretical estimate. In fact, when using an LED ceiling lamp, the heat generated by the LED chip and the impact of the inrush current on the LED diode should also be considered. Excessive current is still easy to break down the diode characteristics of LEDs. Then these factors will lead to LED lamp damage. When considering these principles, LED panel light manufacturers suggest that when using LED ceiling lights, we must learn to avoid the factors that cause damage to LED ceiling lights.
How to replace the Led light if it is not on
First, turn off the switch, with the help of the folding ladder, remove the shell of the led ceiling lamp, and check whether the lamp tube appears dark and dark. If so, it is very likely that the lamp tube has been damaged. It must be replaced. This kind of LED tube can be bought in hardware stores. It is recommended to choose a well-known brand.
Secondly, if the lamp tube is still in good condition, you should try to tighten the joint of the lamp tube to see if there is poor contact. This situation is also relatively simple to operate, and it is also easy to happen.
Then, if none of the above problems occur, you can check whether the ballast is in good condition, whether there is a burning smell, and whether the appearance of the ballast has a black burning phenomenon. If so, it is very likely It's a ballast problem. Just replace one, the ballast is more expensive than the lamp.
Finally, it is to check whether the contact head of the led light has electricity. If not, it should be a switch or line problem.
According to the above operation, you can basically find the cause of the defect by checking from the lamp head to the line. At the same time, we should also be careful not to turn on and turn off the LED ceiling light quickly, which will generate inrush current and affect the service life. At the same time, we must keep the air circulation in the room and avoid the humidity in the room.
How to disassemble the led lampshade
How to remove the square ceiling light? First, grab the frame of the ceiling light and pull it down. Next, you will see the spring inside. Then press the spring inward toward the ceiling to remove the ceiling light. Second, try to remove the square gusset next to the ceiling light. This can be removed because it is stuck. Third, prepare a suction cup hook that can suck the glass, suck it on the aluminum alloy part of the edge, and slowly pull down the four corners in a loop to remove the ceiling lamp.
How to remove the dome light? The first step is to remove the lampshade and remove the fixing screws. Or, use a straight hand to stabilize the lampshade to prevent the lampshade from falling and breaking, and then slowly rotate the lampshade counterclockwise, and it can also be removed quickly!
