LED lamps are very common lamps in modern life. Why LED lamps may not be bright or weak during use?

  1. What is the reason why the led light does not light up?
  2. The packaging and protection of the LED light strip is not perfect, causing the lamp beads to be damaged by collision during transportation.
  3. The solder joints of the LED light bar have virtual soldering. The vibration during transportation causes the solder joints to fall off and the light strip does not light up.
  4. The quality of the solder is poor. During the bending process of the LED, the solder joints are easy to crack and fall off.
  5. The bending angle is too large during installation, which leads to the separation of the solder joint of the LED light bar from the copper foil during installation, resulting in no light.
  6. The solder resist layer of the LED light strip circuit board is too thick, and the solder and the circuit board cannot be completely integrated during welding, which is also a phenomenon of virtual welding.
