led lights are extremely common lamps in modern life, led lights in the use of the process may not appear bright or have low light and other situations, why is this? Today by PChouse for you to answer one by one.
led lights do not light up what is the reason
1, LED light bar packaging protection is not perfect, resulting in damage to the lamp beads during the transport process by impact.
2, the LED strip soldering points have false welding phenomenon, the vibration during transport caused by the solder joints off and lead to the strip does not light.
3, the quality of solder is not good, LED strip in the process of bending the solder joints are prone to brittle crack, fall off phenomenon.
4, installation bending angle is too large, causing the LED strip solder joints and copper foil separation and lead to not bright.
5, LED strip circuit board solder resist layer is too thick, solder and circuit board can not be completely integrated together when welding, is also a false soldering phenomenon.
led lights do not light up but there is a weak light how to repair
1、Replacement of new light strip
If the led lamp because of the aging of the lamp or damaged, you can just change the lamp inside the lamp, without replacing the lamp housing. You can buy a suitable type of light back, cut off the power, use a screwdriver to remove the screws, remove the bad strip, replace the strip with a new one.
2, replace the new drive power
