The bedroom light is double-controlled, with two switches. After turning off the light, the light flashes every five seconds, and other light in the bedroom is normal. What's wrong with that? How to deal with it When the fluorescent lamp is turned off, it flashes because the switch controls the zero line and the live line should be controlled correctly. There is a jingle for interior designers. Change the fire line and put it under neutral light.

Or there is an indicator light on the switch, or the switch leaks slightly because it is dirty.

For these reasons, after the lights are turned off, there is still electricity in the live wire, and the filament will discharge the fluorescent powder, and the lights will be on.

Because the circuit is not connected, the electrons on the phosphor cannot be released in time, and the voltage difference between the live wire and the phosphor does not reach a certain degree, so the lamp is dim.

After a period of time, the electrons on the phosphor are gradually released, and when the fire line reaches a certain voltage difference between the phosphors, it will be discharged again.
