Common Faults And Solutions Of LED Lights

Fault 1: LED does not light up

1. According to the instructions of the LED controller, first we have to check the input terminal of the LED controller and whether the 220 volt Power Supply is normal. Then check whether the output of the 20-30 volt DC power supply is normal. When the power supply is normal, we will check the LED lights.

2. It can be measured with an electric pen. The light bulb is mostly caused by the problem of the controller, so if you check the output end is abnormal, replace the controller. If you have strong hands-on ability, you can also disassemble and find the reason by yourself to fix it yourself.

Fault 2: LED is dim

The dimming of the LED lamp is generally due to the failure of some of the lamp beads, so we can use a multimeter to check the quality of the lamp beads one by one. Of course, it is also possible that a group of lamp beads is broken. Find out the broken lamp beads and replace them according to the model. This also requires a certain amount of hands-on ability.

For the diode gear of the multimeter, use the red and black test pens of the multimeter to touch the positive and negative poles of the lamp beads. If the lamp beads are bright, it is good, and if it is not bright, it is broken.

Trouble three: LED light is dimly bright

This is usually the case with poor-quality LED lights. Another problem is that the lights are turned on and off to the zero line when the lights are not paid attention to at home. LED lights are very sensitive and can light up with a weak current. All households use electronic switches to turn off the lights and light up. No matter what kind of situation causes the light up, we can use a relay to solve it perfectly, because the relay Control the live line and neutral line to be on and off at the same time.
