Led patch light is broken, how to change LED patch light can not repair

Guide: The LED patch light is to assemble the lamp on the circuit board, or on the hard board. There may be many friends who are relatively unfamiliar with led patch lights. Generally, the patch light strip is very soft. Most of the materials used are PCB, or FPC, etc., and his brightness is also very high, and the angle of illumination is relatively large, generally more than 120 degrees, and is illuminated. The time is also very uniform, especially the shape is very small and exquisite. Then led patch light is broken how to change, LED patch light can not be repaired, below we mainly to understand how the LED patch light is broken, learn together!

Led patch light is broken how to change

1, led patch light is broken how to change, if the led power supply is damaged, go buy a voltage, current and other power of the same parameters, to replace.

2, led patch light is broken how to change, if the led light is damaged more, and the damaged LED patch light is concentrated in the same area, you can cut off the damaged section and re-weld.

3, led patch light is broken how to change, if you have a certain basic knowledge of electronics, go buy the same type of LED lights, carry a soldering iron, re-weld. But then again, there are a lot of led patch light components on each led light bar, one or two bad, no effect on the brightness.

LED patch light can not be repaired

LED SMD lamps can not be repaired, LED SMD lamps are not bright, mainly for two reasons, one is the problem of the light source, and the other is the problem of the power supply. At present, the light source of the LED patch light is composed of LED lamp beads. First, disconnect the power supply of the home, open the lamp cover, and use the multimeter to measure whether the LED light source is broken (the patch lights are generally connected in series), if , look at the style of the light source, go to Taobao to buy a same light source to replace it, you should pay attention to the voltage range of the light source when buying, you must buy the same voltage source.

Led patch light

If you use a multimeter to detect the light source is no problem, then see if it is a power supply problem, the general LED patch light is an external power supply method, then buy a power supply directly.

What is an LED patch light?

LED SMD lamps are made of FPC circuit boards, LED lights, and high quality silicone casing. Waterproof performance, safe and convenient to use low-voltage DC power supply, various colors and bright colors; outdoor use can resist UV aging, yellowing, high temperature resistance, etc. This product is widely used in building contour lights, entertainment venues, decorative lighting, advertising decoration The field of lighting.
