8 reasons why LED light strips do not light up

After we buy back a new LED light strip, sometimes it is inevitable that it will not light up. Although this probability is very small, we should also be aware of the common reasons why LED light strips do not light up.

.The packaging of LED flexible light strips is not well protected, causing the lamp beads to be damaged due to impact during transportation.

2. There is a weak solder joint on the LED flexible light strip. The vibration during transportation causes the solder joint to fall off and the light strip does not light up.

3. The LED flexible light strip has a small amount of solder and the solder joints fall off.

4. The welding quality of the LED flexible light strip is not good, and the solder joints of the LED flexible light strip are brittle and fall off during the bending process.

5. The installation bending angle of the LED flexible light strip is too large, causing the solder joints of the LED flexible light strip to separate from the copper foil, resulting in no light.

6. Excessive squeezing of the product when installing the LED flexible light strip may cause the LED flexible light strip chip to be damaged or the solder joints to be deformed and fall off and not light up.

7. The solder mask layer of the LED flexible light strip circuit board is too thick, and the solder and circuit board cannot be completely integrated during welding, which is also a virtual soldering phenomenon.

8. The LED flexible light strip cannot be twisted during installation. If it is twisted, the solder joints of the LED flexible light strip will fall off and the LED light strip will not light up.

Of course, these phenomena are not very common, but it does not rule out such situations. Therefore, we must pay attention during transportation and installation, because once the light strip is damaged, it will be very troublesome to repair.
