It is also possible that the positive and negative poles of the link are not in the right way, and the positive and negative poles of the LED light will not be lit when they are reversed.
The voltage required for LED lights is particularly low, so the emitters are connected in series, so one is broken and the other is not lit.
1. The driving power supply of all the lights is damaged. >>>More
The ordinary way is to replace the LED light board.
DIY method, find the broken lamp beads of the LED light board, and replace the LED lamp beads. >>>More
I don't know how many drivers you have in this lamp, from the fault phenomenon it looks like it is caused by poor contact, it is recommended to check all the lines to see if there is any bad contact, reconnect it, open the driver, and see if the circuit board inside is warped or broken. Re-weld.
No need to buy a new one, show you a way.
With this design, you can see that this single is divided into two halves for power supply, half is controlled by a rectifier, and the other half is broken, it must be a problem with the rectifier, or the connection failure of the entire light strip, you can replace the light strip or replace the rectifier, and the price is relatively cheap. >>>More
