8 reasons why LED strip lights do not light up

After we buy back a new LED strip light, 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 strip lights do not light up.

The packaging of LED flexible strip lights 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 strip light. The vibration during transportation causes the solder joint to fall off and the strip light does not light up.
3. The LED flexible strip light has a small amount of solder and the solder joints fall off.
4. The welding quality of the LED flexible strip light is not good, and the solder joints of the LED flexible strip light are brittle and fall off during the bending process.
5. The installation bending angle of the LED flexible strip light is too large, causing the solder joints of the LED flexible strip light to separate from the copper foil, resulting in no light.
6. Excessive squeezing of the product when installing the LED flexible strip light may cause the LED flexible strip light 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 strip light 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 strip light cannot be twisted during installation. If it is twisted, the solder joints of the LED flexible strip light will fall off and the LED strip light 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 strip light is damaged, it will be very troublesome to repair.
