Is there any replacement method for damaged LED lamp beads on SMD? Can the SMD LED bead be repaired? The SMD LED bead light is not working, mainly due to two reasons: one is the problem with the light source, and the other is the problem with the power supply. At present, the light source of SMD LED lights is composed of LED beads. First, disconnect the power supply at home, open the lampshade, and use a multimeter to measure whether the LED light source is broken (SMD lights are usually connected in series).
If so, take a look at the style of the light source and go to Taobao to purchase a similar light source and replace it. When purchasing, pay attention to the voltage range of the light source and purchase a light source with the same voltage. If a multimeter detects that the light source is not a problem, then it depends on whether it is a power supply issue. Generally, SMD LED beads use an external power supply method, so simply buy a power supply and replace it.
How to replace a damaged SMD LED light bead? If the LED power supply is damaged, buy a power supply with the same parameters as voltage, current, etc. and replace it. If there are many damaged LED lights and the damaged SMD LED bead lights will gather in the same area, the damaged section can be cut off and welded from scratch. If you have a certain basic knowledge of electronics, go buy LED lights of the same model, hold a soldering iron in hand, and weld from the beginning.
