The LED light is broken, don’t worry, here are the solutions to three failures

2021/08/30

ED lamps are energy-saving, high-brightness, long-life, and low-failure rate. They have become the favorite luminous body 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? Too extravagant! In fact, the cost of repairing LED lights is very low, the technical difficulty is not high, and ordinary people can operate it.

The 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.

We provide two maintenance solutions based on 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 by these two methods:

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

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

Second, a large amount of damage

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

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

The starter is damaged

Most of the LED lamp failures are caused by the starter-if the lamp does not turn on at all, or the lamp flickers after being turned on, the starter is probably broken.

The starter cannot be repaired, so it can only be replaced with a new one. Fortunately, the new starter is not expensive. Pay attention to three points when buying a new launcher:

1. Pay attention to the appearance of the connector-the starter connector looks as follows (if the starter is male, the lamp bead board is female; vice versa)
