What causes LED bulbs to flicker?
After the LED lights in the house are closed, if there are still flashing problems, there are many reasons. We need to investigate one by one, and then we can prescribe the right medicine after finding the reason.
1. There may be a wiring problem. When wiring, under normal conditions, the front should be connected to the switch, and many people will directly connect the front to the light, and the neutral line should be directly connected to the light, but the wrong connection will cause the problem of flashing.
2. There may be a problem with the switch. Some people buy the switch, but its conductivity may not be particularly good. After being closed, there is still electricity inside the wire. In this situation, the light will flash when the light is turned off.
3. The problem with the wire. If the power of the wire we use is not matched and exceeds the load current, perhaps the wire is aging, resulting in poor insulation. At this time, there will be voltage on the wire. Even after the light is turned off, it will flash and flash.
4. Some people choose the switch with an indicator light. When it is closed, it is still in the on state, and the problem of flashing will also occur.
