LED ceiling lamp, why is it bright after closing the switch?
There is still leakage after the switch is switched off, or the switch is switched off by a zero line and a circuit formed by leakage of electricity. According to the actual situation analysis, or let the electrician to see. For reference.
After the switch is slightly bright, the built-in switch power supply has leakage phenomenon, replace a new power supply
Hello, this situation is generally due to FireWire and zero line connection caused by the inverse, and only need to change the line with the zero line can be solved! I hope I can help you!
You or you get an electrician to see you, you look at this lamp is not control FireWire, zero line control if it is to happen; if the control will need to check the FireWire, zero line is bad, whether good insulation between the fire and fire control, should consider changing the line.
Many people say that the off switch, lights and light or flash, actually not electrical wiring or lamps, energy-saving lamps and LED lamps are now popular, after a long line switch, power capacitor through the line of arrival between the lamp, accumulated to a certain voltage, the starting circuit light bulb. The resistance of a 470K ohm can be connected at the 220V entry line of the lamp holder to release the induced current, so that the problem of the light or flashing of the lantern can be effectively prevented. I also have electronic hobbies, LED lamp house flash is using this method to solve, some people say I don't agree with the capacitor, capacitor voltage because of problems, once the breakdown, short circuit will cause tripping, the resistance will not.
