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.

LED lamp, crystal quality, size, and is related to the power supply, need constant current and constant voltage, light is not serious, the constant current tube is not the quality of the solution is to change the lamp, but the power is not good, so we should change the power, but need to support, so, or change the lamp,,,
Q:Led why does the ceiling lamp change brightness once a switch is applied?
The ceiling lamp is provided with a plurality of lamp groups which are respectively connected with different output parts of the sectional switch, and the input of the opening switch is connected with the switch of the switch. In this way, once the switch is switched, the output of the sectional switch is switched once.
