There may be many reasons for LED lights to turn on and off for a while. The following are some common reasons and solutions:
The power supply system is unstable: It may be due to the instability of the power supply system that the LED lights cannot work normally. You can try to restart the power supply system once and observe whether the LED lights return to normal.
Power circuit component damage: If the power supply system is stable, it may be a part of the power circuit for the LED lamp is damaged, resulting in the LED lamp cannot emit light normally. In this case, the LED light can be sent to the maintenance site for repair or replacement of the LED light.
Poor contact of the power switch: Poor contact of the power switch that controls the LED light may also cause the LED light to turn off for a while. You can check that the switch is in good contact, and if the problem still cannot be solved after re-opening, you may need to replace the switch.
Driver or lamp bead problem: If the number of LED lamp beads is normal, but the lamp bead is off for a while, it may be a problem with the cross-flow driver of resistance and capacitance step-down. You can check whether the capacitor inside the driver is damaged, or use a multimeter to measure whether the electronic components inside the driver are broken, and replace the damaged parts.
Lamp holder or wiring poor contact: if the number of LED lamp beads is abnormal, it may be poor contact between the lamp holder and the switch wiring. These wires can be checked to see if they are loose or disconnected and reconnected or replaced.
Lamp bead damage: If a lamp bead in the LED lamp bead is damaged, it will also lead to the overall light is not bright. This can be done by observing whether the lamp beads are black or visibly damaged, or by using a multimeter
