The main reason is the failure of the filter capacitor
1. The LED lamp bead does not match the LED drive power supply. Normally, a single 1w lamp bead can withstand the current: 280-300ma, and the voltage: 3.0-3.4v. If the lamp bead chip is not of sufficient power, it will cause the light source to flicker. Phenomenon, if the current is too high, the lamp bead will turn on and off when it 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 is turned on.
There will be flashes and flashes at the beginning of work, for example: 20w floodlight housing is used to assemble 30w lamps, and this will happen if the heat dissipation work is not done well.
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 light:
When the light flashes after turning off, first confirm the wiring problem. The most likely problem is the zero line controlled by the switch. At this time, it should be corrected in time to avoid danger. The correct way is to switch the live line and connect the neutral line to the light.
If there is no problem with the circuit, it is possible that the LED lamp generates a self-inductive current. The easiest way is to buy a 220V relay and connect the coil in series with the light to solve the problem.
Precautions:
The LED lamp bead does not match the LED drive power supply. Normally, a single 1W lamp bead withstands the current: 280-300mA, and the voltage: 3.0-3.4V. If the lamp bead is too high, it will turn on and off. 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.
