This role should be handled together with the previous role. The dimming or not bright light of the lamp may be in this kind of environment.
1. UV LED lamp beads are not bright
The lamp beads of the LED lamp beads are divided into strings, and the lamp beads on each string are connected in series, and the strings are connected in parallel. Therefore, if one lamp bead on this string is destroyed, it will cause this string of lamp beads to not light up. Assuming that one lamp bead in each string is destroyed, it will cause all the lights to go off. Assuming that one lamp bead in each string is destroyed, the capacitance or resistance on the driver should be considered to be effective. The destroyed lamp bead and abnormal lamp bead can be seen from the appearance. The destroyed lamp bead has a black dot in the center, and this dot cannot be erased.
2. Inside the red circle is the destroyed lamp bead
Assuming that the number of destroyed lamp beads is small, the two soldering pins behind the destroyed lamp beads can be soldered together with an electric soldering iron. Assuming that the number of destroyed lamp beads is excessive, it is recommended to buy a lamp bead board to replace it to prevent affecting the brightness of the lighting.
Three, the LED lamp bead flashes after turning off the light
When the light flashes after turning off the light, the first thing to do is to acknowledge the role of the distance. A possible role is the zero line of the switch control. Such moments should be corrected in real time to prevent danger. The accurate way is to switch and control the outpost and connect the neutral line to the light.
Assuming that the circuit is not working, it is possible that a self-inductance current has occurred in the red laser module. The most concise method is to buy a 220V relay, connect the coil to the lamp in series, and then you can handle it.
