1. The LED light bead does not match the LED drive power supply. Normally a single 1W light bead can withstand 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. If the current is too high, the light beads will turn on and off if they can't bear it. Serious phenomena will burn the gold or copper wires inside the lamp beads, causing the lamp beads to not light up.
2. It may be that the driving power supply is broken, so long as it is replaced with another good driving power supply, it will not flash.
3. If the driver has the over-temperature protection function, and the material heat dissipation performance of the lamp cannot meet the requirements, the over-temperature protection of the driver will flash and go out when it starts working, for example: 20W floodlight housing is used to assemble 30W lamps. This will happen if the heat dissipation is not done well.
4. If the outdoor lights also flicker on and off, then the lamps are 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.
