LED lamps are energy-saving, high-brightness, long-life, and low-failure rate. They have become the favorite illuminator of ordinary household users. However, a low failure rate does not mean that there is no failure. What should we do when the LED lamp fails-replace the lamp? What a luxury! In fact, the cost of repairing LED lights is very low, the technical difficulty is not high, and ordinary people can operate it.

Lamp bead is damaged
After the LED lamp is turned on, some of the lamp beads do not light up, basically it can be judged that the lamp beads are damaged. The damaged lamp bead can generally be seen with the naked eye-there is a black spot on the surface of the lamp bead, which proves that it has been burned. Sometimes the lamp beads are connected in series and then in parallel, so the loss of a certain lamp bead will cause a lamp bead to not light up.
