The new light in the living room, the wall switch is turned on and fully on, and it can only be chan

Either the light is broken, or the switch is broken; Disassemble it first and connect it directly with a wire, if the switch is broken, change the switch yourself.

In the line of the living room lamp, the live wire has a grounding place, and most of the current power supply uses a leakage protection type switch, as long as the leakage, grounding, and short circuit, it will automatically trip.

I remember that there was an exchange space that was an office, and there was a luminous ceiling that was used. I can't remember the specific method, it seems that the ceiling is made of white acrylic material, and the lights are arranged in the ceiling. In this way, when the lights are turned on, the ceiling is lit, but the light source is not visible. >>>More

The sectionalizer is damaged, installed in the lamp, and the problem can be solved by replacing it, generally more than ten dollars.
