It may be that the LED lamp beads do not match the LED driver power supply. Recheck and match the power of the LED lamp beads and the LED driver power supply. It may be caused by the damage of the LED drive power supply, just replace the LED drive power supply of the same type. It may be due to long-term use that triggers the over-temperature protection of the LED driver. Turn off the LED light and wait for the temperature to cool before using it.
