The LED light may come on and off for the following reasons:

LED lamp bead dead light refers to the situation where the LED lamp bead does not light up or the brightness becomes dim. It may be due to problems with the LED lamp bead itself, such as the lamp bead is burned out or aged.

LED lights require a stable driving power supply to ensure their normal operation. If the driving power supply is unstable, the LED light will flicker or not light up.

If the 220V power supply voltage is unstable or the circuit fails, it may also cause the LED to light up and off. At this time, you need to check whether the line and voltage are normal.

If there is a problem with the LED lamp bead itself, it can be solved by replacing the lamp bead.

If the driving power supply is unstable or malfunctions, it can be solved by replacing the driving power supply.

If there is a problem with the line or voltage, it can be solved by checking whether the line and voltage are normal.
