The lamp is not lit at both ends and in the middle, with a slight flicker, why? The manual starter c

The reasons for the light tube to be lit at both ends and not in the middle are as follows.

First of all, check whether the starting voltage of the starter is normal?

Check the lamp, is the voltage at both ends normal?

Finally, check the lamp, whether the contact parts of the two ends are normal?

This is the reason for poor contact, and it has been used for a long time, and there are some aging suggestions in the future, so you had better change the lamp.

1.The starter is broken, replace the starter.

2.The lamp is aging, and the lamp is replaced.

In this case, it should be your launcher, which is commonly known as bubble jumping, and there is a problem. Generally, the problem of bubble hopping can be solved by replacing it.

The fluorescent lamp is not lit at both ends and in the middle, it may be that the starter is broken, and it is recommended that you replace it.

In general, it may be due to insufficient battery or system error.

In this case, the lamp is generally broken, you can replace a lamp and try again.

Hello, friend, this should be the starter, if you have a problem, you can find a professional lamp to take a look.

The lamp is lit at both ends, not in the middle, and there is a slight flicker, it should be a problem with the ballast, and the manual starter can be lit, which should be that the joints at both ends are not in contact.

The two ends of the lamp are on, but the middle is not lit, with a slight flicker of the manual starter energy, it is because the jumping bubble of the lamp is not very good, you have to change it to a new jumper.

What is the reason why one set of switches, two lights on, one light on, and one light not flashing.

Dear, I'm glad to answer for you: a set of switches, two lights turn on the switch, one light is on, and one light is not flashing, what are the reasons as follows; A switch controls two lights, one is on, one is not on, there are probably several reasons, one is not on the lamp, the bulb is broken, there may be a problem with the contact of the lamp holder of the lamp that is not lit, the lamp is not lit, the wire is broken, go to check it, find out the problem, you can restore the light that is not lit, first see if the bulb is broken, if it is broken, replace it with a good bulb, if the bulb is not broken, check whether the lampholder is firmly wired, if there is no problem with the wiring, and then check the line, whether the line is broken.

There may be multiple reasons, generally we have to see whether the power supply is stable, whether the switch of the lamp has poor contact, and at the same time to see whether the joints at both ends of the fluorescent tube are loose and have poor contact. In addition, fluorescent lamps are all rectifiers, which may also be problematic. 1. Switch problem.

The fluorescent tube switch is aging, the internal reed elasticity is poor, and there may be a problem of intermittent connection, which will cause the lamp to be on and not on, you can replace the lamp and the organizer first to see if there is still this problem, if there is still this phenomenon after replacement, it may be a switch problem. 2. Rectifier. The opening of the fluorescent tube requires the rectifier to provide voltage, so the rectifier is a wearing part, so once it is broken, when it cannot provide enough voltage, the lamp will turn on and off, and you can replace it to see if the problem can be solved.

3. Joints at both ends of the lamp. The fittings at both ends of the lamp are spring-controlled, and there are terminals inside. If it is used for too long, the elasticity of the spring will decrease, which will cause the joint to loosen, so that the lamp will turn on and off.

In the case of wearing insulating gloves, press the joint in the middle at both ends at the same time to see if the lamp is stable, if it is stable, it means that the joint is a problem, and it is best to replace the entire lamp group. The above three main reasons must pay attention to the safety operation rules during the inspection, and it is best to ask professional maintenance personnel to operate.

If the lamp can be started (fully emitted), but the above phenomenon occurs again after a few seconds, it means that the lamp is aging, and the lamp pressure drop becomes larger, so the starter cannot stop working, and the lamp will be replaced normally. In emergency use, the starter can be removed when the filament (end of the lamp) is red, so that it can work for a while.

If the filaments at both ends of the lamp are always red, and the lamp is not started at all, it means that the starter is short-circuited, or the power supply voltage is too low, and you can try to remove the starter.

The starter works by turning on the instantaneous high-voltage pulse provided by the ballast when the fluorescent lamp is activated, and once the lamp is ignited, the starter is disconnected. If it doesn't disconnect, you're in the same situation. If you don't want to change it, the line of the base of the starter will light up every time you use it.

If you can't change the starter, you can't change the lamp, and you can't change the light, and then you can't move.

It's all possible, you can't say dead, you have to check them one by one.

1. If the lamp is aging, there will be flickering, and the lamp should be replaced with a new one. Do you know how much time the lamp takes? Also, see if the two ends of the lamp are seriously blackened.

2. The switch controls the neutral line; This is usually rare, and it is purely a misconnection.

3. The starter is bad. (Seems to be called a lighter, right?) ......

In short, the lamp and the starter, which of the two is not good, must be tried separately to find out the cause.

Personal experience is that the chances of a problem with the lamp are higher. It is recommended that you try to change the lamp first.

Another experience is attached: the two sides of the lamp are red but not lit, which is generally the aging fault of the starter. The lamp keeps flickering, as if the light is rolling in the tube, which is usually a problem with the lamp, and a few are the ballast problem (this is consistent with what you said, so I judge that the lamp is not good, right?). ）。

Summary. Dear, the day light has been on and the switch can't be turned off because the route is faulty, it may be the path, the switch does not control the role, it is likely that the return route of the light and the fire line are sticky together. If it's a little bright, it's not a normal glow, or it's a problem with the lamp and ballast.

Qinye shooting, I'm glad to receive your round crack problem: the switch can't make the headlamp keep on, the switch doesn't work, the light is not bright, and I will find it for you: It means that the live wire or neutral line of this lamp has not entered the switch, that is, this switch has not played a role in disconnecting or connecting the circuit at all.

You need to turn the switch back on and connect it. I hope my answer can help you.

Pro, this situation should be the poor contact of the metal contacts inside the light control switch, the moment of opening the air discharge phenomenon, the instantaneous current caused tripping, and this Lu Yuzheng at the same time The internal metal contacts of the switch are in the state of on, and the rocker button is out of order, so when the main switch is turned on, the bulb is also energized and has been lit. The light switch needs to be replaced.

I've got this light cord connected to it, and that's it.

Twisted together and broke.

Dear, the light has been on and the switch can't be turned off, the route is faulty, it may be the liquid hand, the switch is not controllable, it is likely that the return route of the lamp and the fire line are sticky together. If it is a little bright, not a normal glow, it is a problem with the lamp and ballast.

Can I fix it myself?

Dear, if you don't have professional knowledge, it is not recommended that you overhaul it yourself, if you want to replace the parts, I will disassemble it.

Dear, you change the switch controller to see.

Hello dear, I'm glad to answer for you: this situation is most likely caused by the failure of the lamp itself or the poor contact of the sockets at both ends of the lamp. It is recommended to try the following methods to exclude:

1.Replace the lamp: The first thing you can do is to replace the lamp.

If the lamp can be lit up normally after replacement, it means that the original lamp has been damaged. 2.Check the outlet:

If the lamp still does not light up properly after replacing it, then you can check whether the sockets at both ends of the lamp are loose or dirty. If the closure is loose or dirty, wipe it with a clean cloth and make sure the socket is fastened in place. 3.

Check the power supply: If neither of the above methods work, then it may be caused by a power failure. It is recommended to check whether the power switch is on, whether the circuit is damaged, etc., and ask a professional electrician to overhaul it if necessary.

Summary. The reason for the flashing of the electric light is that the zero live wire is reversed Under normal circumstances, after the zero live wire is drawn out from the distribution box, the zero wire should lead to the light junction box, and the live wire leads to the switch junction box. That is, the switch should control the on/off of the live wire.

On one power line, one lamp can't start, the other light is always flashing, and the third light is all right after turning on, what is the fault.

The reason for the flickering of the electric light is that the thick zero live wire is reversed under normal circumstances, after the zero live wire is drawn out by the distribution box, the zero wire should lead to the light junction box, and the live wire leads to the switch junction box. That is, the switch should control the on/off of the live wire.

If the connection is reversed, the switch controls the on/off trace code of the neutral line, which will cause the voltage to exist in the state at both ends of the lamp. As a result, a weak current is generated between the fire wire and the earth, which causes flickering for fluorescent lamps and LED lights, which are more sensitive than the state mountains.

Solution: The direction of the zero line of fire must be changed in time. The reverse connection of the zero live wire will not only cause the lights to flicker, but also cause harm to the maintenance personnel during the maintenance of the lamps.

This phenomenon of voltage instability occurs because some people use overpowered electrical appliances, which causes this reason and reduces the use of high power at home.

Poor contact with the power supply is a problem caused by the aging of the line, or the line has been bitten by rats.

The life span has expired or is broken.

If this happens, you may need to replace it with a new one.

The switch protection red light is always on, and the light is not bright but occasionally flashes, which may indicate a failure of the LED tube or power supply. The specific solution is as follows: World Head.

1.Check the wiring: First of all, check whether the connection line between the LED tube and the power supply is in good contact. If you find that the connection is loose or the conductor is disconnected, you need to replug or replace the corresponding wire.

2.Replace the LED tube: If the LED tube fails, you can try replacing the entire tube. The power should be turned off, the lamp should be removed, and a new lamp should be installed.

3.Replace the power supply: If the power supply fails, you can replace the entire power supply, pay attention to choose the power supply suitable for the LED tube.

4.Check the fuse: Some LED tubes will have their own fuse, if the fuse is blown out, the LED light will lose its work. It is necessary to check whether the fuse is blown and replace it with a new one.

In short, if the switch protection red light is always on, and the lighting is not on but occasionally flashing, you need to check the status of the circuit, LED tube, power pants and fuse to find out the cause of the failure. If you have difficulty in dealing with it yourself, it is recommended to seek help from a professional electrician or brand service center.
