What is the reason why the lights at home are still flashing when they are turned off? Incorrect wiring method. When they are closed, the neutral line is disconnected, not the live line. Need to change the connection mode of the switch.
There is a street lamp switch in my house. Why is the light still flashing? Your switch just broke the zero line, and the live wire still has electricity for the light. This kind of electricity without loop can also ionize the luminous body, but it cannot be shaped into an electron flow because there is no loop. There can only be flashing light in the secret. As long as the switch turns off the fire line.
What is the reason why the desk lamp flashes? The lamp tube of the desk lamp often flashes for the following reasons:
1. The lamp tube is broken and needs to be replaced;
2. The lamp tube bayonet of the desk lamp is loose and the contact is poor, so it can be tightened again;
3. The line of the desk lamp is loose or virtual. Find the fault point and tighten the power cord.
4. The voltage is unstable.
Why is the light flashing? Your lamp uses electronic ballast. . Caused. The simplest and most effective way is the main power switch socket at your door. Two zero fire lines. Adjust the position. . It doesn't matter. Remember to turn off the main switch.
What is the reason why the light bulb flashes after closing the circuit? It is estimated that the switch is connected to the zero line, so the light bulb still has electricity after the switch is closed. The power cord should be switched, so that the switch can control the live wire.
What is the reason why the light bulb still flashes when the lights are turned off? Reason:
① The switch is mainly connected to the zero line to control the live wire.
② Then there is an indicator light on the switch.
Due to the above reasons, after the lights are turned off, the live wire is still charged, and the filament of the live wire will discharge the fluorescent powder, and the lamp will light up.
Because the circuit is not connected, the electrons on the phosphor can't be released in time, and the voltage difference between the live wire and the phosphor doesn't reach a certain level, so the lamp becomes 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.
This is the mechanism of' flash'.
This "flash" light is actually very dark and not obvious during the day.
Solution:
All switches are not on the live wire, that is, the zero line and live wire at the main switch are connected backwards, so just switch them around.
Why are all the lights on the third floor flashing? Power supply is caused by three phases and four wires. First, the voltage is unstable. Second, the zero line is not in good contact, but the lighting is too bright at this time. Third, the load at the power supply end is heavy.
What is the reason why the electric wand is flashing? It's time to change the light.
