What's the main reason for led high bay not work?

In the process of using LED high bay lights, we may encounter the situation where the light is not bright, or the light is dark and then bright, or the light is flashing. This situation occurs mainly because of the power supply and light source. The problem is not that the lamps are completely broken. So we don't need to buy a new one as soon as we see this situation, we need to understand the reason firstly, and then solve it in a targeted manner, so that we will get a brand new LED high bay light.

The reasons and solutions for the sudden failure of LED high bay lights:
1.the light source is broken

When the lamp is assembled, the craftsmanship is not perfect, the lamp bead and the heat sink cannot be in good contact, and the thermal paste is unevenly applied. In addition, if the quality of the lamp bead itself is poor, it will burn out if it is lit for a long time.

2.the LED driver is broken

The led driver problem, because some manufacturers use low-quality power supplies at low prices, and the product quality is unqualified. After a long period of use, the lights will burn, the lights will flash, or the lights will light up after a while.
Treatment method, if the problem is in the light source, the SMD type of led high bay light can replace the entire light board with SMD leds, and the COB type of led high bay can replace the COB. It is necessary to pay attention to the heat conduction. If the power supply is broken, you can only replace it with a new one.
