What are the reasons why the LED light bar is not on in use

More and more large shopping malls and supermarket buildings are decorated with LED light strips, which make us feel happy while enjoying the beautiful scenery. But sometimes, the use of LED lights for a long time, there will be more and more dark or does not light up, then led lights do not light up, what are the reasons? We will explain to you today:

1. Transportation damage: the packaging protection of the LED light strip is not perfect, resulting in the damage of the lamp beads in the process of transportation. Or, the welding point of the LED light strip has the phenomenon of false welding, and the vibration in the process of transportation causes the welding point to fall off, resulting in the light strip is not on.

2. Process defects: LED light bar solder less, solder easy to fall off. Or the solder quality of LED light bar is poor, the solder joint of LED flexible light bar is easy to produce brittle crack and fall off in the bending process. It is also a phenomenon of false soldering that the solder and the circuit board can not be completely integrated when the solder layer is too thick.

3. Improper installation: the bending angle of LED light bar is too large when it is installed, resulting in the separation of LED flexible light bar solder joint and copper foil. If the product is over extruded during the installation, the LED flexible light strip chip will be damaged or the solder joint will be deformed and fall off and will not light up. Therefore, it is specially reminded that the user should not twist during installation, so as to avoid the solder joint falling off and causing no light.

Therefore, the above problems need to be avoided when selecting LED light strip, so as to ensure better quality and longer service life of LED light strip.
