The bedroom doesn't turn on LED lights, but it often flashes by itself. What happened?

The reason why the lights flash at home may also be that there is something wrong with the lights themselves, and the part that often goes wrong is the lamp tube. The reason for the general increase of flash is the simplest treatment method, and the problem can be solved by replacing the new lamp directly. Because the beginning of the power supply is connected to the zero line, the solution is to change the beginning of the power supply to the live wire of the power supply.

If the switch head still flashes after being connected to the live wire. That is, switch leakage or switch connection line leakage, this tiny leakage enters the electronic ballast of energy-saving lamp rectifier to store energy, and abnormal lighting work occurs and appears repeatedly. If the power supply voltage at home fluctuates and is unstable, the flashlight at home will happen. If this happens infrequently, you can temporarily ignore whether it happens occasionally, because it has no impact on life. If the frequency is high, it is suggested to deal with the unstable property voltage. Then ask a professional electrician to check at home to see if it is a wiring problem caused by unstable voltage at home. If you also encounter intermittent lights at home, it is recommended to find a professional electrician to check and repair, because electricity is a dangerous thing, and people who have not received professional study and training are prone to danger. The above is an introduction about what causes the flashing of lights at home and how to deal with the intermittent flashing of lights. If you have any other troubles in house maintenance and decoration, you can write to me privately and leave a message. I think I will definitely give you an answer.

The switch correctly controls the live wire ③ If the switch controls the live wire, the traditional mechanical wall switch is used, or it emits light, that is, the neutral wire is charged. It is a common phenomenon that the neutral line is charged. If the neutral wire is not well grounded, the three-phase load of the transformer is unbalanced, the line is too long, the line diameter is thin, or the neutral wire current is too large, it will cause the neutral wire to be charged. Solution: Re-ground the neutral line or carry out low-voltage transformation (this needs to be solved by the property through the power supply company). LED light bar 4. Non-isolated driver, light source patch and substrate leakage Many lamps are driven by inferior resistors and capacitors for cost reasons, or the quality of light source patch is poor, and there is leakage between patch and substrate. The capacitance effect of copper-clad substrate and substrate can also cause light leakage. This is why in a room, some lights are on and some lights are not.
