The lights at home are still slightly bright after the switch is turned off at night, how to solve i

This is usually the case of induced electricity.

It can be solved by adding a miniature relay, or the switch can be replaced with a dual-control switch.

At the same time, it is connected to the zero line to solve the problem. All of the above need to be operated by an electrician.

There are two reasons: one is that the switch is connected to the neutral line, which should be adjusted to the switch to control the live wire.

Second, if it is an LED, either replace the first-class one, or add a control relay to completely cut off the live wire and the neutral line.

Check whether the control lights are switched on or off by the live wire. If so, then it is a problem with the quality of the lamp, and the average person can only change the lamp a little bit. Some people may add capacitors to solve the problem.

The light bulb at home is still slightly bright after being turned off at night, which is the reason for the light bulb, so that even if you turn off the light and don't need to turn on the light in the middle of the night, you can see that this kind of light bulb is such an effect, if you buy a new lamp with no afterglow, there will be no afterglow after turning off the light.

It is possible that the neutral wire and the live wire are reversed. You can consult an electrician first. Or try a new light. Because some energy-saving lamps will do this.

According to your description, if this situation occurs, you can swap the two wires inside the switch, which should solve the problem. Thank you for your understanding and support!

After the light is turned off, it will be on, which means that the live wire and the neutral line of the lamp are reversed, resulting in the existence of current, and the line should be changed in time to avoid short circuit caused by line aging.

Hello, it is recommended to unplug the switch or find a store to repair it in time, and the daily necessities at home should be maintained in time.

The lights at home are still slightly bright after the switch is turned off at night, how to solve it?

Let's change the light bulb.

This is usually only available on lamps with a bit of ballast, not incandescent lamps. The main reason is that the electrician does not distinguish between the zero live wire when wiring, and the switch does not control the live wire, resulting in a weak current flowing.

This is normal! Because many light bulbs nowadays have such a phenomenon, especially one that seems to be chargeable, and can be lit for several hours as if it is powered on.

1. It is very likely that the total incoming line of your home is zero, and the fire is reversed, resulting in the light switch control zero and not fire control, you can pour the bus down.

2. Now there are a lot of switches with power indicators, for LED lamps, due to the existence of switching power indicators, the LED lights will have an impact on the LED lights, causing the switch to be slightly bright after the switch is turned off, and it will be eliminated after removing the indicators.

There are two possible scenarios:

1. The "0" line of the switch is broken, the live wire is not broken, there is induction, it will glow or there is leakage current, it will also glow.

2. The "fire" wire of the switch is broken, and the circuit has leakage current, and the leakage current is enough to light up the LED.

The same goes for the lights in my house! A lot of LED lights are like that!

The reason why the light is still slightly bright when the switch is turned off is that after the switch controls the zero line, turning off the light only cuts off the power circuit of the lamp, and the live wire is still connected to the lamp, and the lamp will glow.

If the above problems are solved, the lamp will still be lit after turning off the light at night, and it should be considered that the zero line is live.

Theoretically, as long as the switch is broken, there will be no voltage on the zero line of the lamp, and the induced current will not be formed.

In real life, it is very common for the neutral line to be electrified, such as the neutral line is not well grounded, the line is too long, the wire diameter is thin, or the neutral line current is too large, which will cause the neutral line to be electrified.

1. When the switch controls the neutral line, not only will the power circuit not be cut off, but the live wire will also be connected to the lamp, which will cause the lamp to emit a faint light. 2. Most switches have indicator lights, if the indicator lights are still energized after turning off the lights, the current will flow to the lamps, causing the lamps to emit a faint light. 3. When the dual-control switch is used at home, there are many wiring methods, which will cause the lamps to emit a faint light.

1. When the switch controls the neutral line, not only will the power circuit not be cut off, but the live wire will also be connected to the lamp, which will cause the lamp to emit a faint light.

3. When the dual-control switch is used at home, there are many wiring methods, which will cause the lamps to emit a faint light.

There are a variety of reasons why the bulb keeps being slightly lit after the light is turned off, and the reasons and solutions are as follows:

1. The switch controls the zero line, and the fire line directly stares into the lamp.

This is one of the more common causes of luminescence. After turning on the zero line of light control, turning off the light only cuts off the power circuit of the lamp, and the live wire is still connected to the lamp, so the lamp will glow.

Solution: Reconnect the circuit and let the switch control the live wire.

2. The switch has an indicator light or an electronic switch.

Most switches have an indicator light inside, and if the indicator light is energized when the light is turned off, then there will be current flowing through the lamp. Some lamps and lanterns use electronic lighting, such as infrared switches, voice-activated lighting and remote control switches.

These switches do not completely cut off the circuit, causing the luminaire to glow when the light is turned off.

Solution: Remove the switch indicator or replace it with a mechanical switch.

3. The wiring method of the dual control switch is wrong.

There are many wiring methods for dual-control switches, and if the electrician uses this method of terminal stuffing, it will glow after turning off the light.

Solution: Rewire the wire according to the neutral line inlet and control the live wire.

4. The neutral line is electrified.

If the above problems are solved, and the lights will still be on after turning off at night, you need to consider whether the neutral line is live. Theoretically, as long as the switch is broken, there will be no voltage on the neutral line of the lamp, and the induced current will not be formed. In daily life, the zero line band is only electricity.

If the neutral line is not well grounded, the line is too long, the wire diameter is thin, or the neutral line current is too large, it will cause the neutral line to be electrified.

5. Solution: It is difficult to solve the problem of zero line electrification, unless the transmission line is transformed, so that the lamps do not touch the conductor, such as: walls, roofs and steel keels, etc., can also reduce the luminous phenomenon, but can not be completely solved.

After turning off the lights, there is a faint light that will not waste electricity

When the lights are turned off, there is still a faint light, because there is a small amount of electricity passing through, and a certain amount of electricity will be charged. However, as long as the switch is turned off, it will not consume power. To consume electricity, a current loop must be formed, and as long as the wiring is not wrong, the light will not consume electricity.

Hello, the situation that the switch is turned off and the light is still slightly bright may be due to the following reasons:1There is a leakage phenomenon in the circuit, which causes the current to be completely cut off, resulting in a faint light on the lamp.

2.There is a problem with the bulb itself, such as an aging or damaged filament, that prevents the bulb from going out completely. In this case, you can take the following measures:

1.Check whether there is leakage in the circuit, you can use a multimeter to test the car, find the location of the leakage and repair it in time. 2.

Replace the bulb and make sure there is no problem with the bulb itself. In addition to the above two situations, it may also be caused by poor wire contact or aging of the switch. If the above measures do not solve the problem, it is recommended that you have a professional electrician for service and repair.
