1. The LED lamp beads do not match the LED drive power. Normally, a single lamp bead that meets the voltage of 1W needs to withstand current: 80-300mA, voltage: 3.0-3.4V. If the lamp bead chip is not sufficient, then Will cause the chip strobe phenomenon, the current is too high, the lamp beads can not bear it, flicker, in severe cases will burn the built-in gold or copper wires of the lamp beads, resulting in the lamp beads do not light.
2. It is possible that the driving power supply is broken and needs to be replaced with a new one.
3. If the driver has a protection function that cuts off power when the safety temperature is exceeded, and the material’s heat dissipation performance cannot meet the requirements, the driver protection function will start to flicker.
4. If the outdoor lighting also has strobe, it is water in the lighting. The consequence is that the lamp beads are burned.
