Why does the light turn on for a while and then turn off on its own?

There may be several reasons why the lights go out after a while, let's find out together.

1. Poor contact, it may be that the contact at the switch is poor, the wire connected to the switch is not tightly in contact with the switch, and there is a virtual connection phenomenon, so it will be bright and not bright for a while, reconnect the wire at the switch, and the lamp holder is not in good contact, and the line connected to the lamp holder is not tight, and there is a virtual connection phenomenon, so it will be bright and will not be lit for a while.

2. If the switch is a problem, rewire the switch, if it doesn't work, change the switch and try to connect it online.

There is another kind, I have encountered it myself, the wire is short-circuited, the decoration master ceiling hit the hidden nail on the wire, when it is on, it is bright when it is closed, and it is not bright for a while, and finally it is found out.

3. You may have installed a light-controlled electric light.

Finally, the reason why the light will go off after a while is not single, it may be burned, or it may be that the temperature is too high, I hope it will help you.

If the light turns on for a while and turns off automatically, it means that the switch is in poor contact or that the wiring is faulty.

When I got home last night, I sat in the living room and watched TV, the light in the living room went out automatically, I went to repeat the switch several times, and found that the light still couldn't be turned on, thinking that the lamp was broken, so I went to turn on the light in the aisle, and the light in the aisle can be turned on normally! I went to the living room to watch TV again, and a few minutes later, the light in the living room was automatically turned on again, and the light in the living room was turned on automatically and turned off automatically. . .

Hello, maybe your light is voice-activated or has an auto-off function.

Summary. 1.The lamp is equipped with a timer function, which will automatically turn off when the preset time is reached.

2.The smart light will automatically turn off when it senses that the surrounding brightness is bright enough. 3.

The battery of the lamp is depleted, and the power cannot be continued and the power is extinguished. 4.The light's switch or connection port is faulty, and the disconnected circuit causes it to not work.

5.The bulb reaches the end of its life and cannot be extinguished. 6.

Power access problems, power outages or unstable current turns off lights. 7.The electronic controller of the lamp is faulty and cannot control the switching state of the lamp.

8.Moisture-proof or safety devices trigger disconnect circuit protection devices. 9.

The user accidentally touches the switch or unplugs the power supply to turn off the light.

Hello, there may be several reasons why the lights go off automatically:

The smart light will automatically turn off when it senses that the surrounding brightness is bright enough. 3.The battery of the lamp is depleted, and the power supply cannot be continued, so it goes out.

4.The switch or connection port of the lamp is faulty, and the disconnection circuit results in non-band leak operation. 5.

The bulb reaches the end of its life and cannot be extinguished. 6.Power access problems, power outages or unstable current turns off lights.

1.Bulb aging: Bulbs that have been used for a long time may cause the filament to break, which will cause the bulb to turn off automatically.

2.Circuit failure: The circuit of the electric light may fail due to aging, short circuit, etc., causing the electric light to go out automatically.

3.Overvoltage: The circuit voltage of the lamp may be too high, resulting in premature aging of the bulb, short circuit and other problems, causing the lamp to turn off automatically.

4.Poor contact between the lamp attendant and the lamp holder: Poor contact between the bottom of the bulb and the lamp holder may cause the light to go out automatically.

At this time, you can try cleaning the bottom of the bulb and the lamp holder to ensure good contact.

My suggestion is to first check whether the congratulatory line of the lamp is normal, and then you can try to replace it with a new electric tease or hidden pool or bulb, if the problem in the mountain hall still exists, it is recommended to find a professional to check and repair.

The reasons are as follows: 1. It is a light-controlled lamp.

2. If it is not a light-controlled bulb, it should not only be on at night and off during the day, what you observe is only on at night because the background light is too dark at night, so you can feel the slight noise of the lamp. At this time, the switch does not work, indicating that the switch has been broken, the biggest possibility is that the switch is short-circuited, such as a very fine copper wire short-circuited, or the insulation is broken.
