The fluorescent lamp is not lit at all, and can you fix one of the three lights if it is not lit

One possibility that the fluorescent lamp is not lit is that the filament is broken. In this case, you can remove the lamp, put it to your ear and shake it gently, if you can hear a slight "dingding" sound at both ends, it means that the lamp has been scrapped and must be replaced with a new one;

If only one end of the sound is heard, it means that only one end of the magic wire is broken, as long as the magic tube does not leak, you can still wrap a few circles of copper wire in the two pins at one end of the broken wire, and you can continue to use it for a period of time.

If the fluorescent lamp suddenly stops lit, it may be caused by a short circuit or poor contact. You can use a voltage tester to test the two binding posts of the switch, if the voltage tester is not lit, it may be that the fuse is broken or there is a short circuit fault on the road.

If one binding post is lit and the other is not, it means that there is no problem on the line. You can turn the starter in the seat several times, and then use the index fingers of the left and right hands to squeeze the lamp holder to the middle, and turn the lamp tube with the middle finger and thumb at the same time, and the lamp will be on.

If the lamp is extinguished after the two hands are released, or the lamp is not lit after switching it several times, it means that the lamp and the lamp holder are not in good contact, as long as you use a screwdriver to move the copper sheet in the lamp holder, you can eliminate the fault.

If you squeeze the lamp tube and lamp holder, and it still does not light up, you should check whether the wiring has fallen or is loose, and you should reconnect it and tighten the screws. There is also a situation where the ends of the lamp are red and there is no beating, which may be the starter has a disease. If the switch is pulled off, remove it to start.

As soon as the piece dies and the moon lamp jumps on, the lamp does not light up after installation, and a new starter must be replaced.

Just replace the thermopress.

There are three kinds of lights, and one can be repaired if it is not lit.

We just need to replace the segmentation controller and it will be solved. Because the three-color lamp has three colors, the LED tube of different colors is connected to different lamp lines, and then the switch is rotated through the segmented controller to switch the lamp color.

Therefore, if one of the lights of the three-color lamp is not lit, then it is because the segmented controller of the lamp is faulty, if two of the lamps can be lit normally, it means that the other line has indeed been damaged, and the segmented controller can be replaced.

The tri-color lamp usually refers to the ceiling lamp with three light modes, different color modes are connected to different light lines, and their light emitting modes are switched through the segmented controller, that is, the rotation switch. For example, when you press the switch, the three-color light will show a cool color; Press the second time after turning off, and the three-color light will show neutral light; After turning it off, switch it for the third time, and the light color will be displayed as a warm color.

The tri-color lamp is very practical, and the life span is also very long, and there is basically no problem with using it for ten years without accidents, and in addition, there is generally no problem with color decay. LED three-color ceiling lamp is made of LED light source, with warm white 3200K, cool white 6500K, neutral light 4500K three light colors, directly connected to the home circuit, through the contact to continue to press the household switch to achieve light color switching, constant power, constant brightness, very suitable for urban and rural market sales.

In addition, although the three-color lamp can switch the cold and warm of the lamp color, it is generally impossible to adjust the brightness, therefore, this also limits the usability of the three-color lamp, but if it is just a broken lamp and does not turn on, it can be repaired.

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.

Make sure the lamp isn't broken, that isBallastsIt's broken, or the starter is broken, or it's a wiring problem. If it is an LED tube, it is a problem with the control line. It is recommended to ask a professional maintenance personnel to deal with it.

LED lamp refers to the light source of the lamp with LED as the light emitter, as opposed to the fluorescent lamp.

The tube is more energy-saving, inexpensive, high life, drop resistant and simple structure, which is a good substitute for fluorescent tubes in the future.

Size:

Straight tube fluorescent lamps are divided into T12, T10, T8, T6, T5, T4, T3 and other specifications according to the diameter of the tube. The combination of "T + number" in the specification indicates the millimeter value of the pipe diameter.

What it means: a t = 1 8 inches, one inch is; The number represents the number of t, such as t12=, and this standard also applies to led tubes.

Fluorescent tubes:

This fluorescent lamp is a double-ended fluorescent lamp. Common nominal powers are 4W, 6W, 8W, 12W, 15W, 20W, 30W, 36W, 40W, 65W, 80W, 85W and 125W. Pipe diameters are T5, T8, T10, T12.

G5, G13 for lamp heads.

T5 color rendering index 30, good color rendering, ideal lighting effect for colorful items and environment, small light attenuation, long life, average life of 10,000 hours.

It is suitable for clothing, department stores, supermarkets, food, fruits, **, display windows and other colorful occasions. T8 has better color light, brightness, energy saving and service life, and is suitable for hotels, offices, shops, hospitals, libraries and homes and other occasions with simple colors but high brightness.

The two ends of the lamp are shining, but the middle is not lit. This is usually due to the aging of the lamp or the difficulty of starting up due to the voltage being too low. The heat dissipation of the lamp can be treated and the configuration ballast can be replaced.

or starter, or adjust the voltage to maintain the rating.

The light is flickering or there is a rolling light band in the tube. This kind of phenomenon is generally caused by the link of the starter or ballast is not bright, and sometimes it is caused by the poor quality of the lamp or the temporary phenomenon of the new lamp.

There are three kinds of lights, and one can be repaired if it is not lit. The tri-color lamp has three colors, the LED tube of different colors will be connected to the filament with different nuclear resistance, and then the color of the lamp can be switched by the segmentation controller (i.e. the backup switch). Therefore, if there is a phenomenon that the color of the tri-color light is not bright, it is usually because the segment controller of the light is faulty, two of the lines can output normally, and the other line is damaged to know that the bulb is not lit, if this happens, please replace the segment controller to solve the problem.

If you don't know how to repair it, you can also find a professional electrician to repair it.

Precautions for repairing lamps.

1. It is necessary to turn off the power supply before replacing it to prevent the risk of electric shock.

2. Avoid continuous high temperature when repairing LED bulbs. Usually in the case of Spike source, the two important components of LED bulbs are LED and FPC, which are products that cannot withstand high temperatures continuously. If the high temperature continues, the covering film of the FPC will blister, causing the LED bulb to be scrapped.

If the high temperature is too long, it will also burn out the chip of the LED bulb.

3. Anti-static measures should be taken when repairing LED bulbs. Since LED is an electrostatic sensitive component, it is easy to burn out the LED if there are no anti-static measures when repairing the LED bulb. Therefore, the soldering iron used in maintenance should be guaranteed to be an anti-static soldering iron, and maintenance personnel must also wear anti-static tools such as electrostatic rings and anti-static gloves.

Kiss. Hello! The three types of light are incandescent, fluorescent, and LED.

If one of the lights doesn't come on, the feasibility of the fix depends on the specific cause. 1.Incandescent lamp:

If the incandescent lamp does not come on, it may be that the filament has burned out or the bulb has blown out, in which case the bulb needs to be replaced. Sometimes it is caused by poor contact, and the problem can be eliminated by checking the connection cable and plugging in the head. 2.

Fluorescent lamp: If the fluorescent lamp is not lit, it may be a faulty circuit or the lamp has reached the end of its life and needs to be replaced. Checking circuits and fluorescent lamps often requires checking whether the tubes are broken, whether the circuits are energized, whether the circuit parts have reached the time to be replaced, and so on.

3.LED light: If the LED light does not light up, it is often caused by the LED burning or the LED driver being damaged.

In this case, the bulb needs to be replaced or the LED driver circuit needs to be adjusted to fix the problem. In short, whether or not you can fix a light that doesn't come on depends on the specific cause. For example, the fruit is because the bulb or lamp tube is burned out and needs to be replaced; If it is a circuit fault, the circuit needs to be checked.

If you're not sure how to fix it, seek help from a professional.
