There are four dialable clips above the four bezels of the lampshade, and the cover can be removed by dialing the direction.
The life of the LED lamp is very long, if the lamp bead is broken], the cause should be identified, and after the cause is found and the symptom is solved, the damaged lamp bead should be replaced with the same lamp bead, so as to ensure that it will not be damaged again after replacement.
Now it is certain that the live wire and switch are not broken, and if it is confirmed that the lamp is in good condition, it must be the neutral line disconnected. >>>More
Generally, there is an open circuit of the LED lamp beads in series, and it can be replaced or directly short-circuited.
First look to see if the bulb is broken, and then see if the power cord is not connected properly.
