When we decorate the house, everyone will definitely meet our lamps. Many people will choose our spotlights because of more fashionable homes. In this way, when we are at home, we also have fun in bitterness and enjoy the happiness brought by the light. But if any product is used for a long time, there will be some problems. Some people will encounter that our led spotlights don't work, so they can't be used. Let's take a look at the reasons why led spotlights don't work.

1.What is the reason why the LED spotlight doesn't work?

1, sometimes the whole light doesn't work. If it doesn't light up, it may be that the lamp bulb or the driver is broken. Everyone should remember to check in time. But generally speaking, the driver is broken and can be replaced directly. Remember to choose the driver. The driver is the heart of the lamp. If you have a bad heart, it's no use changing it.

2, sometimes it flashes, and it can be replaced if conditions permit. Replacement is also very simple. It is possible that the lamp bead is broken to see if it is normal. If a light bulb is short-circuited, it proves that the light bulb is broken. If it is a high-power lamp bead, it can be removed and replaced. If it is a patch lamp bead, it will be more troublesome. Either replace the lamp board or scrap the whole lamp.

3. There is also a case where it is bright at first, but it will not be so bright after a while. This is not a serious situation either. When the overhead light flashes, it is more likely that the drive is broken. If the drive is broken, replace it directly. It is also possible that one of the lamp beads is broken. Please refer to the previous article for treatment.

The light bulb will turn black directly after it is lit, which may be caused by poor heat dissipation, and everyone has to replace it. The lamp beads set themselves on fire and died. The quality of lamp beads is unstable, and the voltage applied to other lamp beads is too high, which is easy to burn out. There is also unstable power supply and excessive current. Please refer to the light bulb and power supply processing method mentioned above for the processing method. If the heat dissipation is not good, check whether there is heat dissipation paste between the lamp board and the radiator and whether the connection is intact.
