Self-maintenance and troubleshooting skills for common small faults of LED lights The common minor faults of LED lamps can be repaired and eliminated by yourself. If it is obviously burned by water or short circuit, you can replace it by yourself. In this case, a shell is valuable. If the shell is expensive or the whole set is ugly, such as spotlight street lights, you need to change the light source and driver, and change some sealants yourself.

It is recommended to find this manufacturer to buy supporting facilities, measure the size and take pictures. Don't put it in when you buy the light source, especially don't buy it separately, don't be cheap! If it is suddenly not bright or dark, but other circuits are intact, that is, other electrical appliances are fine. In this case, the lamp is usually its own nerve, that is, broken.

This situation is very common. Let's take down the lamp first and analyze it slowly! Taking a simple LED bulb as an example, first open the cover and pick the blade along the edge gap. After turning it on, see what the light is powered by.

Whether it is the board connected to the light panel or the components soldered on the light panel, that is, the stand-alone IC and the DOB scheme, the stand-alone IC is a bit troublesome. The first point of troubleshooting: first check whether the lamp beads are in good condition. The black spot in the middle of the lamp bead is basically bad.

If there are only one or two bad ones, you can make them yourself. You can poke and solder a piece of wire. If it's much worse, just replace it.
