What is the reason for the lights to keep flickering? What s the matter with the lights flickering a

Reason:

1. First of all, it may be because the neutral wire and the live wire are reversed when the wiring is reversed, and when the connection is reversed, the current in the circuit flows through the diode and the lamp flashes and flashes.

2. If the light bulb is installed at home, it may be because the base of the bulb is in poor contact, in this case, because the connection is not tight, it is loose, which causes it to be flashing all the time.

3. It is also possible that the lamp itself has malfunctioned, and the wick inside is aging, so we need to replace the lamp.

1. First of all, we need to save electricity and don't turn on all the lights in the house, which will cause a waste of electricity. Before going out or going to bed, be sure to check if there are still lights on in your home, and if so, turn them off in time.

2. If the light bulb at home is not lit, when replacing it, be sure to turn off all the power supply first to prevent electric shock accidents during replacement.

There is an error in the wiring: the neutral wire is reversed, which means that the neutral wire and the live wire are connected incorrectly, which will cause the light to flicker non-stop. Voltage instability:

It could be that someone in the home uses a high-powered appliance. Poor contact with the power supply: This is a problem with the aging of the line, or the line has been bitten by mice.

Indoor humidity causes short circuits: For example, the lights in the bathroom, the bathroom is damp, and the lamp port is in contact with water vapor for a long time, which will be affected by the situation of short circuit, resulting in flickering and eventually burning out the lamp. The lamp itself is faulty:

If you find that the lighting fixtures in your home are flickering (on and off), the first thing that should be thought of is that the lights are broken. Dust affects lamp port contact: Dust accumulation at the lamp port can also cause the light to flicker.

Dust falls on the lamp port, causing the lamp to be in poor contact with the lamp port, so it keeps flashing, but does not burn out the lamp. LED lamp beads do not match the LED driver power supply: when the bulb of the LED lamp does not match the driver, the bulb cannot bear the energy from the drive, and the lamp will keep flashing.

The drive over-temperature protection function is turned on: if the drive has over-temperature protection function, and the material heat dissipation performance of the lamp cannot meet the requirements, the over-temperature protection of the drive will flash and go out when it starts to work. Water ingress from the lamp:

If the outdoor lamps also have a strobe on and off phenomenon, it means that the lamps are flooded. Maintenance of lamps and lanternsIt is best to install lampshades when installing lamps to effectively block external pollution. Use proper cleaning methods.

Do not alter the structure of the lamp during the cleaning process, you can take it apart for cleaning, but be sure to remember the order of installation. Do not turn on and off the lights frequently, as the temperature of the filament will rise sharply and reduce the service life.

Electric light is one of the essential household appliances in every household, and electric light brings light to our lives. Without the advent of electric light, our lives would lose their light. In the process of using electric lights, we sometimes find that the lights are still "flashing" after being turned off, if this phenomenon occurs, what should we do?

What is the reason why the lights keep "flashing" even after they are turned off?

One of the reasons why the lights keep "flashing" after they are turned off: under normal circumstances, the neutral line is connected to the light junction box.

The live wire is connected to the switch junction box, so that the switch can better control the lights. If the line is reversed, the switch is disconnected from the neutral line, but the light is connected to the live wire, which will still produce a voltage difference between the two sides of the light, which will cause the light to flicker after the light is turned off.

The second reason why the lights keep "flashing" after they are turned off: there are many switches nowadays, all of which have an indicator light on them. However, such a switch is not very good, because even after the light is turned off, the indicator light is still on, which means that the switch is still on.

At this time, a small stream of electric current flows through the lamp, causing a flicker.

The third reason why the lights keep "flashing" after they are turned off: this situation mainly occurs in places where the wires are relatively dense. Due to the close proximity of the wires, especially when using high-power electrical appliances, a certain amount of induced current will be generated.

When the induced current occurs, the flashing of electric lights, especially LED lights, will be more noticeable.

What's the workaround

What can we do about this phenomenon? It was necessary to change the direction of the zero line of fire in time. The reverse connection of the zero live wire will not only cause the lights to flicker, but also cause injuries to the maintenance personnel during the maintenance of the lamps.

When the fluorescent lamp (energy-saving lamp) is working, the argon gas in the tube ionizes to generate heat, and the heat makes mercury.

Vapor is generated, and mercury vapor is ionized and emits intense ultraviolet light.

When excited by ultraviolet light, the phosphors inside the tube wall emit near-white visible light.

This is a good way to do it.

Check the wiring, the screw is loose and only need to be tightened, if the soft wire is burr, the burr can be removed, or directly replaced with a hard wire. This is a problem with the aging of the wiring, or the wiring has been bitten by mice. Change to a new one!

As a common electrical device, when the light has been used for a period of time, there may be signs that the light has been "flashing" after being turned off. If this happens, it's time to replace the lights. Only in this way can we ensure the safety of people's lives and property and ensure the better use of electric lights.

Reasons and solutions for the lights to keep flashing:

1. The lamp itself is faulty

If you find that the lighting fixtures in your home are flickering (on and off), the first thing that should be thought of is that the lamp is broken, especially if there is only a single lamp in the home, then the possibility of the lamp failure is higher.

Solution: It's very simple, replace it with a new one. If the problem persists, then it can be ruled out that it is the lamp itself.

2. Poor contact of lines or lamps (poor contact leads to burning of air switches).

Poor contact of the wiring or the luminaire itself is also a common cause of flickering of electric lights. There are many factors that cause poor contact, such as the virtual connection of the connector caused by the aging of the line at home, the loose connection of the lamp head terminal, etc. For example, if the flashing frequency of the electric light is high and there is a loud sound, it is likely that the strobe phenomenon is caused by poor line contact.

Solution: Carefully inspect the wiring and lamp head. First of all, disconnect the power supply, start from the wiring of the lower port of the air switch of the lighting circuit in the distribution box, check all the joints in the line, find the place where the slag elimination connection in the line is not firm, and re-process.

If the line is aging, it is best to replace it with a new one.

3. Voltage fluctuations

If the electricity load in the home is too large at a certain time, it may also cause instantaneous voltage fluctuations in the lighting circuit, resulting in slightly darker lamps.

Solution: The method of detecting whether the voltage is stable is also very simple, you can use a multimeter to measure the voltage in the lighting circuit, under normal circumstances, the normal fluctuation range of the lighting voltage is between 198 and volts. Beyond this range, it is necessary to pay attention, at this time we can check whether there are high-power appliances in use at the same time in the home.

Fluorescent Lighting Principle:

When the power switch is just closed, the mercury in the fluorescent tube is heated and evaporated by the filaments at both ends of the lamp to form a thin mercury vapor, and the high pressure generated by the ballast is added to both ends of the lamp, so that the mercury atoms are ionized and electrons, and the electrons collide with the mercury atoms after acceleration, so that the gas is quickly broken down, resulting in arc discharge and ultraviolet excitation.

Ultraviolet light then excites the phosphor applied to the tube wall to emit a soft light. It does not contain infrared rays, so its light is very mild and does not hurt the eyes; Because it does not contain **, it is more energy-efficient to use; It also emits a lot of beautiful colored light.

This is determined by the nature of the chemicals contained in phosphors, such as magnesium tungstate, which glows blue-white and glows reddish when coated with cadmium borate.

The reasons why the lights do not flash are as follows:

1. The voltage is unstable, and this reason is relatively common. When the capacitance of the home is at a low value, and there are more electrical appliances used, then the voltage will be unstable, and the lights will flicker at this time.

2. The power supply is loose, and some lights need to be plugged in. If the plug is loose, the light will also flicker, just unplug it and plug it back in.

3. The control switch of the lamp has an indicator light, and the indicator light is recharged and discharged with a side repeat, resulting in flickering. The solution is very simple, just remove the indicator light.

4. When wiring, the zero line is misconnected, and the lamp body is charged and causes flickering. If that's the reason, just reconnect the live wire correctly.

Hazards of electric light strobe:

1. Although the strobe speed is very fast, it is basically imperceptible. But our retina is still able to respond to it, and the high frequency of light burns the body's brain cells and kneneon body, which also affects our eye control.

2. The trajectory of the eyeball will be affected by stroboscopy, which will damage our vision.

3. A strobe with a frequency of 100 Hz may also increase the incidence of headaches, but this is a special case for special populations.

4. For some production lines that use fluorescent lamps, if there is a strobe, it will make people visually fatigued or even dizzy, which will affect work efficiency and may also cause production accidents due to fatigue operation.
