There are two main reasons why the LED light is off:

One is the problem of light source, and the other is the problem of power supply. At present, the light source of LED lights is composed of LED lamp beads. First, disconnect the power supply at home, open the lamp cover, and use a multimeter to measure whether the LED light source is broken (the lamp beads are generally connected in series). If so, check Look at the style of the light source, to buy the same light source and replace it, pay attention to the voltage range of the light source when buying, you must buy a light source of the same voltage.

If you use a multimeter to detect that the light source is okay, then it depends on whether it is a power problem. Generally, LED ceiling lights use an external power supply method. Then you can buy a power supply to replace it. Some LED light manufacturers use a bad power supply. The power supply is the most prone to problems.

method one:

1. Before turning on the LED light, measure the voltage of the power supply and the current flowing through the LED.

2. Then take apart and check all the key parts one by one: driver or power supply, LED lamp beads, and replace all broken lamp beads.

3. Find out the cause of the LED lamp bead damage. If there is overcurrent, reduce the drive current immediately. Check if the driver is faulty, and also find out the reason, repairable and replaceable.

If the LED power supply is damaged, buy a power supply with the same parameters as voltage and current and replace it.

If the LED lamp is damaged more and the damaged LED patch lamp is concentrated in the same area, the damaged section can be cut and re-soldered.

If you have some basic knowledge of electronics, you can buy the same type of LED light, carry a soldering iron, and re-solder. But then again, there are many LED patch light elements on each LED light bar, one or two of which are bad, and have little effect on brightness.

Method Two:

1. If the LED power supply is damaged, buy a power supply with the same parameters as voltage and current and replace it.

2. If the LED lamp is damaged more and the damaged LED patch lamp is concentrated in the same area, the damaged section can be cut and re-welded.

3. If you have some basic knowledge of electronics, you can buy the same type of LED lamp, carry a soldering iron, and re-solder. But then again, there are many LED patch light elements on each LED light bar, one or two of which are bad, and have little effect on brightness.

From the packaging volume points: 3528, 2835, 3535, 5050, 5630, and so on. It is widely used in lighting fixtures. The processing method is generally: reflow soldering. (Divided into low temperature welding, low temperature welding, high temperature welding) In addition, the gap of the chip LED is generally negative. (Depending on the packaging method, it will change.) SMD lamp beads are cheap and can be mass-produced； high-power lamp beads have high brightness, long life and convenient DIY.
