The light is slightly bright after the lamp is turned off, and the solution is solved

Luminaire slightly bright solution:

First, the switch controls the reason for the zero line, the switch controls the zero line when the electrician is wired, or the zero fire is reversed when the electrical box enters the line. The switch controls the zero line, and the fire line is still connected to the lamp, which will emit a shimmer. Solution: Adjust the wiring and let the switch control the fire wire.

Second, the double control switch has an error in the connection method The double control switch has several wiring methods, if the wrong connection method is used, it will also be slightly bright after turning off the light. Solution: Install the normal control fire wire connection method to rewire.

Third, non-isolated drive, the light source patch and substrate leakage on the market Many lamps and lanterns are driven by inferior resistance capacitance step-down for cost considerations, or the quality of the light source patch is poor, and there is leakage of the patch and the substrate. Substrate copper clad and substrate capacitance effects can also cause light leakage. This is why in a room, the lights are bright and some are not. Workaround: Replace the isolated drive power supply.

Fourth, the zero line is charged In fact, the zero line is charged is the most fundamental reason for the light after turning off the lights. If the switch controls the fire wire, uses an ordinary wall switch, or emits light, it is zero line charged. Zero-line charging is a very common phenomenon. If the grounding of the zero line is not good, the three-phase load of the transformer is unbalanced, the line is too long, the wire diameter is thin, or the zero line current is too large, it will cause the zero line to be charged. Solution: Re-ground zero or low-voltage retrofit.

Fifth, the lamp protector finally recommends a simple and effective solution, that is, the use of lamp protector, which can completely solve various reasons for shimmering. Connect the protector to the lamp, and when the lamp is turned off, the connection between the lamp and the mains will be disconnected. Even if the zero line is charged, the chip is leaking, and the switch is misconnected, there will be no current conduction to the luminaire.

The above problems can not be solved, you can pay attention to, there are problems at any time to contact.
