1. LED explosion-proof beads do not match the LED drive power supply. Normal single-footed 1W lamp beads bear current: 280-300mA, voltage: 3.0-3.4V, if the lamp chip is not enough, it will cause light and light source flash phenomenon. If the current is too high, the lamp beads cannot be afforded. It will be light and one destroy. The serious phenomenon will burn the golden or copper wire built by the lamp beads, resulting in the lamp beads not bright.

2. It may be that the driving power is broken. As long as you change to another good driver power, it will not flash.

3. If the driver has a temperature protection function, the heat dissipation performance of the explosion -proof lamps cannot meet the requirements, and the driving temperature protection starts to work. Lighting, the heat dissipation work will not be done well.

If the outdoor explosion -proof lamps also have a frequent flashing phenomenon, it is the lamp in the water. The consequence is that it will not light up. The lamp beads and drivers are broken. If the driving waterproof is good, it will just break the lamp beads and change the light source.
