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 withstands current: 280-300ma, voltage: 3.0-3.4v. If the lamp bead chip is not of sufficient power, it will cause the light source to flicker. Phenomenon, the lamp bead will turn on and off if the current is too high and it can't bear it. A serious phenomenon will burn the gold or copper wire in the lamp bead, causing the lamp bead to not light up.
2. It may be that the driving power supply is broken, as long as it is replaced with another good driving power supply, it will not flash.
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 drive Baidong over-temperature protection is turned on
There will be a flashing phenomenon at the beginning of the work, for example: 20w floodlight housing is used to assemble 30w lamps, it will be like this if the heat dissipation work is not done well.
4. If the outdoor light fixture also flashes on and off, it means that the light has been flooded. The consequence is that it will not light up when it flashes. The lamp beads and driver are broken. If the driver is waterproof, just break the lamp beads and replace the light source.
The solution to the flashing led light:
When the light flickers after turning off the light, first confirm the wiring problem. The most likely problem is the neutral wire controlled by the switch. In this case, correct it in time to avoid danger. The correct way is to switch the live wire to the neutral wire and connect the neutral wire to the light.
If there is no problem with the circuit, it is possible that the LED lamp has generated self-inductance current. The easiest way is to buy a 220V relay and connect the coil to the light in series to solve the problem.
Precautions:
The LED lamp bead does not match the LED drive power supply. Normally, a single 1W lamp bead can withstand current: 280-300mA, voltage: 3.0-3.4V. If the lamp bead chip is not of sufficient power, it will cause a light source stroboscopic phenomenon, current If the lamp bead is too high, it will turn on and off. If the lamp is too high, it will burn out the gold wire or copper wire in the lamp, causing the lamp bead to not light up.
