    The reason is in the switch.

    The new type of switch has a "low-light LED" inside;

    When the switch is disconnected, the headlights of the ceiling are off, and the "low light LED" inside the switch is on, indicating the position of the switch at night;

    This phenomenon can also be attributed to switch leakage!

    When the switch is closed, the headlights of the ceiling are on, and the "low-light LED" inside the switch is short-circuited and does not light up.

    Because the "low-light LED" inside the switch is on, its current flows from the "ceiling headlight", if it is an old-fashioned incandescent lamp, fluorescent lamp, this current is invalid, the light is not on;

    But now you use LED lights, which have high sensitivity, and the leakage current inside the switch also makes the LED headlights shine slightly.

    There is no danger in this phenomenon, the power consumption is minimal, ignore him.

    This question is basically difficult.

    1. There may be parasitic capacitance between the two wires.

    2. The neutral line is not well grounded.

    In this way, you can change it to a shielded wire, so that I think there will be no problem, I am also thinking about this problem, this is not a problem of your family, some people say that it is the problem of breaking the zero line, but it seems to be useless to change it, it is still the same flash, but some people are fine, I think it must be a problem of induction, otherwise, electricity comes from **, except for induction, it is not said to make sense! Give it a try!

    You turn off the air switch first, if there is no longer a glimmer, it means that there is induction electricity (if your switch does not have an indicator light), you say that the two wires of the switch (originally in the first line of pipe), one outside the tube, disconnect the switch, the light is normal, I don't understand what you said about the disconnect switch is connected and turned off or not connected at all, I am making lamps, I have seen this situation you said, you can change an LED transformer, try again.

    I've also encountered this kind of problem, which is the problem said on the second floor, yes.

    If you don't believe it, try a normal switch.

    The main switch is the incoming switch. When the main switch is disconnected, the whole house will have a power outage, not only will the lights go out, but there will be no power on any outlet.

    A power supply is a device that converts other forms of energy into electrical energy. The power supply is based on the principle of "magnetic electricity", which is generated by renewable energy sources such as hydropower, wind power, ocean tides, dam water pressure difference, solar energy, and coal burning and oil residue. Common power sources are dry batteries (DC) and household 110V-220V AC power supplies.

    Brief introduction. High-quality power supplies generally have multi-national certification marks such as FCC, UL in the United States and Great Wall in China. These certifications are professional standards formulated by the certification body according to the technical specifications of the industry for power supply, including production process, electromagnetic interference, safety protection, etc., where the product that meets certain indicators can be used on the packaging and product surface after the certification is passed, and has a certain authority.

    This may be the reason why the fuse is too thick, under normal circumstances, it is safe to trip for short circuit, and it is best to change the fuse to a little thinner, so that the electricity will be safe.

    The reason why the LED light remains on at night after a power failure is that when the electrician installs the power off switch, the power off switch is connected to the neutral line, not to the live line. If the power off switch is connected to the neutral line, the live line will continue to supply power to the LED driver power supply after the power is turned off, so the LED light will be dimmed and bright when the switch is turned off.

    1.The wiring problem caused the lights in the home to be slightly bright after the lights were turned off. We have to understand the wiring of household lamps because when the lights we use in our home are wired, they are connected to the neutral and live lines, and the control lines of the switches actually belong to the live lines.

    When wiring, connect the neutral wire and the live wire to the terminal of the lamp according to the wiring requirements of the lamp.

    2.The light is faintly lit due to a problem with the switch. In fact, the switch problem here is basically some smart switch.

    In particular, some sensor switches and new smart switches are the most prone to this problem. In other words, a smart switch is installed in the home. After turning off the lights with the smart switch, we found that the lights were still a little bright.

    In fact, the current common problem is that it appears on the switch. For example, live and neutral wires cannot be completely disconnected inside the switch, and there is a slight voltage. Then our lights will also be a little brighter at this time.

    3.The light itself is slightly bright. In fact, the probability of this problem happening is still very small.

    After confirming that the switch is normal, we must confirm the problem with the light again, because although the probability of the lamp malfunctioning is very low, we find that the light is still slightly on. However, this problem may also arise if we buy some non-brand lamps that do not have quality assurance.

    4.Wiring problems cause the lights in your home to glow slightly when they are turned off. One of the most typical situations is that the lights and sockets in the home are in the same circuit.

    As we all know, the current division of home circuits is based on the function of use. The most common way here is that all the lighting circuits in the home are one circuit, with separate wires and separate control switches.

    There are two most common reasons. One is that the switch directly controls the neutral line when wiring, and the live wire is directly connected to the lamp. Another reason is that some LED light switches have indicator lights. Nowadays, most people install electronic switches, and there will be a weak current passing through, causing the LED lights to glow.

    Because when the electrician installs the power-off switch, the power-off switch is connected to the neutral wire, not the live wire. Electricians know that the power switch must be de-energized with a live wire, otherwise there will be a risk of electric shock. After the power is off, FireWire will continue to supply power to the LED driver power, so the LED light will also have a faint bright light.

    I hope that friends who encounter similar situations in the future will pay special attention. Safety first. When this happens, don't wonder if the LED bulb is broken, you should turn off the main switch and try to see if you can turn it off!

    If so, there is static electricity and residual charge in the line to which the bulb is connected. The most effective way to do this is to check the line of fire. In general, the main problem with static electricity is the cause of the live wire.

    If it can't be turned off, then the LED bulb can be removed, whether it is off, whether it is no longer dim, otherwise it is the reason why the home distribution box generates a lot of static electricity.

    Many headlights with segments must be divided into zero lines, which means that the red lines (or grey) on the segments are connected to the lines as much as possible. This is the safest method. Most of the time, the light switch is mounted on the neutral line.

    When the switch is turned off, the live wire is still connected and the light is always live, so the light will light up slightly after turning it off. This is not just the case with LEDs. If it is the case with a normal fluorescent lamp, it will also appear dim.

    When the light is turned off, it still glows slightly. It is likely that the LED chip is too sensitive to current. Even if it is a wire, as long as a complete current loop is formed, there will still be a glimmer under various complex inductions, and then you can change a chip.

    Choosing home lighting LED lighting, first of all, we have to look at its color temperature, there are two main kinds, one is warm color, and the other is cold color. If you are in the bedroom or a place to rest, you can choose a warm-colored LED light. Because the light emitted is closer to our skin tone, it will feel warm and comfortable.

    When placed in the bedroom, it can have a soothing effect and effectively improve the quality of sleep.

    Reason: It may be caused by poor wire contact, and it needs to be rewired at high speed; It may be that there is a problem with the power switch and you need to contact a professional for repair.

    Precautions for the use of LED lamps: 1. LED lamps are made of electron-emitting semiconductor materials, which are solid-state semiconductor devices, which can directly convert electricity into light.

    2. The influence of current on LED lamps is relatively large, and the constant current can prolong the service life of LED lamps and reduce the probability of bulb failure.

    3. When buying bulbs, pay attention to choosing well-known brands of LED lights.

    4. Pay attention to safety when repairing the bulb, and be sure to turn off the power supply before disassembling and repairing it, and you must have a certain electrician knowledge to disassemble and repair it yourself.

    Data expansion: LED lamp is a semiconductor material chip, fixed to the bracket with silver glue or white glue, and then connected to the chip and circuit board with a hole in silver wire or gold wire, sealed with epoxy resin around it, to protect the internal core, and finally install the shell, so the LED lamp has good seismic performance. LEDs can directly emit red, yellow, blue, green, cyan, orange, violet, and white light.

    Because the main switch controls all the circuits in the whole house, all of them will be out of power when it is disconnected.

    No current passes through the main switch after it is broken. Naturally, the other lights won't be on.

    Could it be a short circuit? That's why it's like this, and if it doesn't short-circuit, it will definitely not be like this.
