The living room LED crystal lamp light strip is half on and half is not on, indicating that it is two groups of series circuits, possible causes and solutions: >>>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.
Generally, LED crystal lamps have several drivers, which may be broken and can be returned to the factory for repair within the warranty period.
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.
If the circuit voltage is stable and normal, it is recommended to change to another brand of lamp.
