What are the reasons why the LED light bar does not light up during use?

With the continuous development of society, ordinary people are becoming more and more aware of environmental protection and energy saving, so the demand and quality requirements for LED lighting products are also getting higher and higher. With the popularity of lighting products such as LED strips, LED line lights, and LED panel lights, LED strips and LED strips have been widely used in furniture, automobiles, advertising, lighting, ships and other industries.

        More and more large shopping malls and supermarket buildings are decorated with LED light strips, which emit brilliant lights at night, which makes us feel comfortable while enjoying the beautiful scenery. But sometimes, the LED light strip will become darker or not bright after a long time of use, so what are the reasons why the LED light strip is not bright? LEDER lighting will explain to you today:

1. Transportation damage: The packaging protection of the LED light bar is not perfect, causing the internal lamp beads to be damaged by impact during transportation. Or, the welding point of the LED light bar has a false welding phenomenon, and the vibration during transportation causes the soldering point to fall off and the light bar does not light up.

2. Process defect: The amount of solder in the LED light bar is small, and the solder joints are easy to fall off. Or the solder quality of the LED light bar is not good, and the solder joints of the LED flexible light bar are prone to brittle cracks and falling off during the bending process. The solder resistance layer of the circuit board of the light strip is too thick, and the solder and the circuit board cannot be completely fused together during soldering, which is also a phenomenon of virtual soldering.

3. Improper installation: The bending angle of the LED light bar is too large when it is installed, causing the solder joints of the LED flexible light bar to separate from the copper foil, resulting in no light. If the product is excessively squeezed during installation, the chip of the LED flexible light strip will be damaged or the solder joints will be deformed and fall off and will not light up. Therefore, users are specially reminded not to twist during installation, so as to avoid the solder joints falling off and causing no light.

Therefore, it is necessary to avoid the above problems when choosing LED light strips, so as to ensure better quality and longer service life of LED light strips.
