There are six main reasons and solutions for LED lamps to light up slightly after turning off at night. At present, LED has fully replaced halogen and fluorescent light sources due to its advantages of energy conservation, high brightness, and long lifespan.

LED light sources have low excitation current and are appropriately sensitive to voltage and current. During use, they can cause induced luminescence due to various complex reasons. Even after turning off the lights, they will emit low light, affecting normal sleep and accelerating the light decay of the lamps. Generally, it is caused by the following reasons:

1、 The switch operates the zero line.

This is a common reason, as the electrician manipulated the zero line during wiring, or perhaps the zero fire connection was reversed when the electrical box was wired in. The switch controls the zero line, and if it is still connected to the lamp in front, it will emit a faint light. Solution: Adjust the wiring and allow the switch to operate the front.

2、 Dual control switch presents incorrect connection method

There are several wiring methods for dual control switches, and if the wrong method is used, the lights will also turn off and light up slightly. Solution: Install the normal control front connection method and wire it from scratch.

3、 Switch with indicator light, using electronic switches

There is an indicator light inside the switch, and after turning off the light, there will be a slight current flowing through it. If the lamp uses electronic switches, such as infrared, voice control, and remote control switches. There will also be a phenomenon of shimmering after turning off the lights.

Solution 1: Change the switch.

Solution 2: Connect a 500K resistor in parallel at the inlet of the lamp. However, this method requires high technical requirements and is not easy to operate by non specialized personnel. Moreover, if the zero line is charged, the shimmering caused by patch leakage may not be effective.
