When the LED light is used for a long time, there will be weak light, dim light and flicker when the LED light is turned off. Such failures often occur in home circuits.
This is because as long as the faulty LED has a weak current, the lamp is more sensitive to the current, and the LED light will be slightly bright, weak, and flickering.
In fact, after the LED light is turned off, there are only three reasons for weak light, flash or dim light. Let’s talk about how to fix it.
The first reason: switch control
For the correct circuit of the lamp, the neutral wire connects the lamp and the switch under the live wire, and when the switch is disconnected, it returns to the lamp, i.e. the switch controls the live wire. If the circuit is wrongly connected, the live wire connects the light and the neutral wire down the switch, it will become the switch controlled zero.
If the switch control is zero, when the switch is off, the live wire is often charging on the lamp, the live wire will produce a weak current to the ground LED When the switch is off, the lamp is more sensitive to the current, the reason why the LED light will emit weak light.
Solution: Just adjust the switch, live wire and neutral wire that control the light circuit, and use the switch to control the live wire to solve the problem

The third reason: the wires near the LED lights are denser
In household circuits, due to the large number of electrical appliances, the wires we arrange will be denser. For example, when the wires near the lamp are dense, the nearby wires will generate induced current. Because the LED lamp is more sensitive to current, it will appear after the switch is turned off. , the reason why the LED light emits weak light.
Solution: You can buy a 220V intermediate relay to connect the coil LED of the intermediate relay to the two terminals of the lamp, and use the coil to absorb the induced current to completely solve this fault.
