What s going on when the lights are off and flashing

Here's a solution:

1. The neutral line is reversed from the live wire: the direction of the neutral live wire must be changed 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.

2. Induced current: A contactor coil can be connected in series at the position of the lamp to eliminate the weak current in the line. 3. There is an indicator light on the switch

Remove or replace the indicator light inside the switch. 4. The wiring is not firm: check the wiring, the screw is loose and only need to be tightened, if the soft wire is burr, the burr part can be removed, or directly replaced with a hard wire.

5. The life of the bulb expires or is broken: replace it with a new bulb.

Because the switch controls the neutral line, the live wire goes directly into the light. Turn on the circuit and let the switch control the live wire. When the switch has an indicator light or an electronic switch is used, the indicator light of the switch should be removed or the mechanical switch should be replaced.

The wiring method of the dual-control switch is incorrect. Rewire the wire in the same way that the neutral inlet light controls the live wire. Here's why:

1.The switch controls the neutral line, and the live wire directly enters the lamp. This is the most common cause of glow. After turning on the light to control the neutral line, turning off the light just cuts off the power circuit of the light, and the live wire is still connected to the light, so the light will glow, such as flashing.

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

2.The switch has an indicator light or uses an electronic switch. Many switches have indicators inside.

If the indicator light turns on after the light is turned off, current will flow through the light. Some lights use electronic switches, such as infrared switches, voice-activated switches, and remote switches. This switch does not completely cut off the circuit.

It will also cause the light to glow when the light is turned off.

Workaround: Remove the switch indicator or replace the mechanical switch.

3.The wiring method of the dual-control switch is incorrect. The dual-control switch has a variety of wiring options. If the electrician uses the following wiring method, the lights will be turned off and a faint light will be emitted.

The switch controls the neutral line, and the live wire goes directly into the lamp. This is one of the most 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, and the lamp will glow, such as a flashing situation.

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

The switch has an indicator light or an electronic switch. Many switches have an indicator light inside, and if the indicator light is energized when the light is turned off, there will be current flowing through the lamp. Some luminaires use electronic switches, such as infrared switches, voice-activated switches, and remote switches.

These switches do not completely shut down the circuit. It will also cause the lamp to glow when the light is turned off. Workaround:

Remove the switch indicator or replace the mechanical switch.

Precautions for lamp maintenance

Avoid frequent switching: do not switch frequently when the lamp is in use, because the current through the filament is greater than the current when the lamp is started frequently, so that the temperature of the filament rises sharply and accelerates the sublimation, which will greatly reduce its service life, so it is necessary to minimize the switch of the lamp.

Replace the lamp in time if there is a problem: replace the aging lamp in time according to the light source parameters provided by the sign, and when it is found that the two ends of the lamp are red, the lamp is black or has a black shadow, and the lamp does not jump bright, the lamp should be replaced in time to prevent unsafe phenomena such as the ballast burning out.

In people's daily life, lamps and lanterns need to be used every day, but in the process of use, it is inevitable to encounter some problems. Today I will answer for you, and friends who want to know may wish to take a look with us!

1. What's going on when the lights are off and flashing?

Since the fluorescent lamp emits light with a special phosphor, the slightest hint of an electric current can cause it to glow. It is also possible that there is also a small amount of static electricity in the lamp, so there will be a flash of light. It is also possible that the switch controls the neutral wire instead of the live wire, so that a small amount of current will pass through the lamp, causing the fluorescent lamp to flash and flicker.

Second, what are the common faults of lamps.

1. Open the road. Causes: The filament of the bulb is broken, the wire box is open, the lamp holder, switch, fuse is blown or the inlet wire is open, etc.

Consequences: An open circuit will cause no current to pass through the electrical appliance, so that the normal work cannot be carried out.

2. Short circuit. Reason: For example, the live wire connected to the lamp holder collides with the neutral wire, and the two wires in the socket collide.

Consequences: A short circuit caused by the connection between the live wire and the neutral wire, the short circuit will blow the fuse, so the entire lighting circuit will be de-energized, and even the line will be burned, and in serious cases, it will cause a disaster.

3. Overload. Cause: Because the total power of electricity in the circuit is too large, or because the power of a single consumer is too large.

Consequences: The phenomenon that occurs is very similar to the consequences of a short circuit.

4. Poor circuit contact.

Causes: For example: poor contact between switches, lampholders, and wire hanging boxes, poor contact of the fuse in the bulb, poor contact at the joints of the line, etc.

Consequence of the sensitive: It will cause the lights to flicker on and off, so that the electrical appliances cannot work normally.

Summary: The above is what is going on with the lights off and flashing and what are the common faults of the lamps and lanterns, I believe you have a corresponding understanding after reading the above sharing, if you need to learn more about relevant information, please continue to pay attention to Qeeka Home**, which will be answered for you one by one.
