LED lamps are energy-saving, high in brightness, long in life, and low in failure rate, and have become the favorite illuminants of ordinary home users. But low failure rate does not mean no failure. What should we do when the LED light fails - change the light? So extravagant! In fact, the cost of repairing LED lights is very low, and the technical difficulty is not high, and ordinary people can operate them.

After the LED light is turned on, some of the lamp beads do not light up. Basically, it can be judged that the lamp beads are damaged. Damaged lamp beads 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 piece of lamp beads not to light up.

We provide two repair options according to the number of damaged lamp beads.

1. A small amount of damage

If only one or two lamp beads are broken, we can repair them in two ways:

1. Find the broken lamp bead and use a wire to connect the metal at both ends of it to short-circuit it. The effect of this is that most of the lamp beads can light up normally, and only the individual lamp beads that are broken do not light up, which has little effect on the overall brightness.

2. If your hands-on ability is relatively strong, you can go to the Internet to buy the same type of lamp beads (a large package of ten dollars), and replace it by yourself - use an electric soldering iron (blow a hair dryer for a while) to heat the old lamp beads , until the glue on the back of the old lamp bead is melted, remove the old lamp bead with tweezers (don't use your hands, it is too hot). At the same time, install the new lamp beads while it is still hot (pay attention to the positive and negative poles), and you're done!

Second, a lot of damage

If a large number of lamp beads are damaged, it is recommended to replace the entire lamp bead board. Lamp beads are also available online. Pay attention to three points when purchasing: 1. Measure the size of your own lamps; 2. Be optimistic about the appearance of the lamp beads and the starter connector (explained later); 3. Remember the output of the starter Power range (explained later).

These three points of the new lamp bead board must be the same as the old lamp bead plate - the replacement of the lamp bead plate is very simple, the old lamp bead plate is fixed on the lamp socket with screws, and it can be removed directly. The new lamp bead board is fixed with magnets. When replacing, remove the new lamp bead board and connect it with the connector of the starter.
