Led wardrobe light belts are widely used in life, with long service life, energy saving and high efficiency. However, no matter what kind of lamps, they may malfunction after a long time of use. Then, what should I do if the wardrobe light belt does not turn on? How to fix it?

　　1. The power plug falls off

　　If one of the light strips does not light up, check if the plug falls off and the power is cut off, or if the connector socket is broken, if the plug falls off, insert it firmly, if it is broken, replace with a new power adapter. That's it.

　　Second, the lamp bead is damaged

　　Many light strips are not lit because of the lamp beads. There are many reasons for the damage of the lamp beads:

　　First, the solder joints fall off, and the solder joints of the LED flexible light strip are prone to brittle cracks and fall off during the bending process. If it is a false welding, you need to repair it again with a soldering iron.

　　The second is that the led lamp burns out due to voltage reasons-the voltage is too high, the load is too much, the quality of the LED is poor, or because the low-voltage light bar needs an external power transformer, when the internal current is too high and the power is too high, the internal heat If it is not distributed, it is easy to burn out.

　　If the positive and negative voltages at the interface are normal, but the light strip does not light up, it is very likely that a certain LED lamp bead in the light string is burned out. If the lamp bead is burned out, it can generally be observed that the lamp bead turns black. Yes, there are black spots in the middle of the burned out LED chip. If it is determined that the lamp bead is damaged, it is troublesome to replace it by yourself. Our solution is to cut off the power supply, look at the damaged location, and directly find the nearest scissors mouth pattern and cut it off, and cut off the part that is not bright. Just replace this paragraph. Led light strips are mostly 1 meter as a unit. It is easier to cut and change a section than to replace individual lamp beads. If a few meters are broken, buy a few meters and buy more plugs. Remember to buy the same model and color temperature as before.

　　Generally, every 3 lights of the flexible light strip are a small unit, you can also cut off the broken small unit, and then weld the two together. It can also be used, remember that the positive and negative poles must be distinguished, and the joints must be handled well. If it is a hard light bar, you can find the bad light-emitting diode and short-circuit it with a soldering iron, so that the other lights will be on, without affecting the overall use of the light bar.

　　Third, the drive is damaged

　　If the circuit is in good contact, but the light strip does not light up, it may be that the driver is broken, or the driver output is disconnected from the connection part of the lamp bead board. The driver cannot be repaired. You can only replace it with a new one. You can choose to buy it yourself. Write down the output power range of the driver to ensure normal use.
