The main reason is the failure of the filter capacitor

1. The LED lamp beads do not match the power supply of the LED driver. Usually a single 1w lamp bead can withstand current: 280-300ma, voltage: 3.0-3.4v. If the power of the lamp bead chip is insufficient, it will cause the light source to flicker. Phenomenon, if the current is too high, the lamp beads will turn on and off if they can't bear it. In serious cases, the gold wire or copper wire built into the lamp bead will be blown, causing the lamp bead to not light up.

2. It may be that the drive power supply is broken, as long as you replace it with another good drive power supply, it will stop flashing.

3. If the driver has an over-temperature protection function, and the heat dissipation performance of the material of the lamp cannot meet the requirements, the over-temperature protection of the driver will flash and disappear when it starts to work. The lamps and lanterns, the heat dissipation work is not done well, it will be like this.

4. If the outdoor lamps also flicker on and off, it means that the lamps have entered the water. The result is that it flashes and does not light up. The lamp bead and the driver are broken. If the driver is waterproof, just break the lamp bead and replace the light source.

The solution to the flickering LED modeling light:
When the LED light flashes after turning off, first confirm the line problem. The most likely problem is the zero line controlled by the switch. In this case, please correct it in time to avoid danger. The correct way is to switch and control the live wire, and the neutral wire is connected to the light. If there is no problem with the circuit, it is possible that the LED light is producing a self-inductive current, the easy way is to buy a 220V relay and connect the coil in series to the light to fix the problem.
