If the light comes on normally when you turn on the switch, use it like this!
It should be a fault caused by a lack of phase line, and your home incoming line is three-phase!
This is not a problem of zero control and fire control, if you really use LEDs, this kind of problem will not occur.
The usual bai decoration if the lamp in the home.
After turning off the LED power, you can also see the weak light dao line, most of which is inductive internal electricity, the current is weak and weak, and the meter is not run. You can follow the following path to troubleshoot and solve the problem step by step; >>>More
This is the light switch on the zero line, and there is still electricity on the lamp after the light is turned off, such as fluorescent lamps, LED lights, and energy-saving lamps. The solution is to swap the live line and neutral line of the entrance line.
Normally, it is because after turning off the light, the charge stored in the capacitor in the ballast is slowly released, so the weak current lights up the L E D and glows.
