Why does the lamp keep flashing? How can I solve it

The rectifier is damaged, and the electronic ballast is replaced.

The analysis is as follows: 1. As you said, the lamps and starters are all new and good, so it may be that the voltage is low there, which has nothing to do with whether you turn on the lights alone.

2. You take it apart to see if the rectifier is a little zoomed in color, and it is recommended to replace it with a new one.

3. It is recommended that you replace the rectifier with an electronic ballast, so that you don't need to start the glow, and the electronic ballast is also cheaper.

4. Electronic ballast, low voltage can also be started smoothly.

The lamp keeps flashing, it may be that the lamp itself is broken, or it may be that the rectifier is broken, this has to be judged according to the actual situation, generally the lamp is replaced first, if the problem is solved, it is the previous lamp is broken, if it is still, it is the rectifier is broken. However, if you don't know how to use electricity, don't mess around, it's dangerous. It's best to find a professional electrician to take a look, sometimes the switch is broken.

The reason why the lamp flashes and flashes:

1. There is an error in the wiring, that is to say, the neutral wire and the live wire are connected incorrectly, and the circuit is reconnected.

2. The voltage of the electrical appliances used at home is too high, resulting in unstable voltage.

3. The contact between the power supply and the lamp is poor, and the current is not smooth, which will cause the lamp to flicker and flash.

4. The current of the zero line is too large, resulting in the zero line being electrified, and the lamp will also flicker.

It may be that the voltage is insufficient, or the lamp may be broken, it is recommended to find someone to take a look!

If there is a problem with the quality of the light pipe and you need to replace it with a new product, you should check whether the power switch has a broken wire or burned.

There are four possibilities for the situation of LED lamps flashing and flashing, and the specific reasons and corresponding solutions are as follows:

1. LED lamp beads do not match the LED drive power supply, normal single full 1W lamp beads bear current: 280-300mA, voltage: , if the lamp bead chip is not full power, it will cause the light source strobe phenomenon, the current is too high The lamp beads can not withstand the light on and off, and the serious phenomenon will burn the gold wire or copper wire built in the lamp beads, resulting in the lamp beads not lighting up.

2. It may be that the drive power supply is broken, as long as it is replaced with another good drive power supply, it will not flash.

3. If the drive has an 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 start to work, and there will be a flashing phenomenon, for example: the 20W flood light shell is used to assemble a 30W lamp, and the heat dissipation work is not done well. 4. If the outdoor lamps also have the phenomenon of strobe on and off, it means that the lamps are flooded.

The consequence is that it doesn't light up when it flashes. If the drive is waterproof, it is just a matter of breaking the lamp beads and replacing the light source.

LED light daily attention points:

1. After buying back the LED lamp, you should carefully look at the mark of the LED lamp and read the installation and use manual, and then install and use the LED lamp according to the provisions of the manual, otherwise there may be danger.

2. Don't switch on and off frequently. Because the LED lamp is frequently started at the moment, the current through the filament is greater than the current during normal operation, so that the temperature of the filament rises sharply and accelerates the sublimation, which will greatly reduce its service life.

3. When it is found that both ends of the lamp are red, the lamp is black or has a black shadow, and the lamp does not light up, the lamp should be replaced in time to prevent unsafe phenomena such as ballast burning;

Hello: The common problems that cause the fluorescent lamp to flash are: the igniter is aging or the tube is broken, the two ends of the lamp are not in good contact with the tube base, and the line voltage of the lighting electricity is low.

It may be that the rectifier is broken, or it is a starter, but you can buy a starter first

If the rectifier is broken, it's not the starter problem, it's that your switch doesn't control the live wire.

The lamp is indispensable in our daily life, it brings light to our lives and lights up the world. I believe that many friends have encountered the situation of the light flickering and flashing, so what is the reason for the light flickering and flashing? What should I do when using the lamp?

What is the reason for the flickering of the lamp.

The lamp flashes and flashes, perhaps the electronic ballast inside the lamp is broken, in this case, the ballast can be replaced. If the two ends of the lamp are blackened, then it means that the service life of the lamp is about to be reached and the lamp should be replaced with a new one.

What should I do when using the lamp.

1. When there is a problem with the lamp, the fault should be eliminated in time, if the two ends of the lamp appear black, or red, the lamp has been flashing, but not lit when the lamp should be replaced with a new lamp, so as to avoid the ballast being burned out. When using the lamp daily, you should pay attention to maintenance, and you can wipe the lamp with a clean rag frequently. If the lamp is installed in the shower room or toilet, then a moisture-proof lampshade needs to be installed.

2. The kitchen lamp should be installed with a light-colored lampshade, so that the light transmittance is relatively strong and will not affect the cooking. In addition, kitchen lamps should also pay attention to prevent oil fumes, and should choose a style that is easy to clean. If the lamp is not made of metal, it can be wiped with a damp cloth to prevent dust build-up.

3. When installing or cleaning the lamp, the structure of the lamp cannot be changed at will, and the parts of the lamp cannot be replaced at will. After cleaning, the lamp needs to be installed back as it is, and the parts of the lamp cannot be omitted or installed by mistake. When using the lamp, do not turn on and off frequently, the current of the lamp will be relatively large when it is started, if it is started frequently, the temperature of the filament will rise sharply, and it is easy to shorten the service life of the lamp.

Article summary: The above is to introduce to you what is the reason for the flashing of the lamp and what should be done when using the lamp, I hope to help some friends in need.

Aging of the lamp: If the ends of the lamp are black, it means that the lamp is aging, has burned out, and the lamp needs to be replaced.

Starter failure: You turn on the light, the starter is removed, if the light will still be on, it is a starter failure, and the starter needs to be replaced.

Ballast failure: If you have a new lamp, it is likely that the ballast is faulty, and you can reverse the positive source and negative pole of the lamp.

Unstable voltage: The voltage is too low.

1. Go to a nearby hardware store or convenience store to buy a "Qihui device", which is generally universal, very cheap, and the better quality will not exceed 2 yuan.

2. Before replacing the starter or carrying out electrical maintenance, be sure to make sure that the power is turned off and safety is paramount.

3. Rotate the Qihui device in the direction of the arrow in the figure below, if the Qizhou Huihui device has been damaged, you can use the ruler electrician pliers to clamp the center tightly and rotate it out. Take care that your hands are dry.

4. Stuff the starter into it, feel the top until it touches the bottom, and turn it in the direction of the arrow in the figure below and twist it. Take care that your hands are dry.

5. Restart the power supply and test whether the lamp has been repaired. If the lamp still does not shine, it means that the lamp book is burned out, and the lamp should be replaced instead.

The rectifier is damaged, and the electronic ballast is replaced.

The analysis is as follows: 1. As you said, the lamps and starters are all new and good, so it may be that the voltage is low there, which has nothing to do with whether you turn on the lights alone.

2. You take it apart to see if the rectifier is a little zoomed in color, and it is recommended to replace it with a new one.

3. It is recommended that you replace the rectifier with an electronic ballast, so that you don't need to carry the wheel starter, and the electronic ballast is also cheaper.

4. Electronic ballast, low voltage can also be started smoothly.

Because the strobe of the light exceeds the standard, the strobe is ubiquitous in the lamps! But all lamps and lanterns, as long as they are connected to AC, there will be "strobe". The reason for the strobe is that the refresh rate of the two appliances is different.

The higher the frequency, the less visible the strobe. There are two kinds of strobe, harmful and harmless, when the strobe percentage is in the low risk range of 8, the lamp strobe is within the safe range; If it is higher than 8, the lighting product can be considered unsafe.

People often have a tendency called "visual persistence": to perceive things continuously, even if they no longer appear in front of our eyes, we are able to see "continuous images" rather than a discrete set of static images. The LED light source flickers at high frequency and is imperceptible to the naked eye.

So stupid, we see that the lights are on until the power is completely turned off.

Instead, it's actually a series of images captured in quick succession. Images are captured in frames per second, and when we play games together, this constant vision tricks our brain into seeing the events on the screen as a continuous fluid movement. When the number of frames per second exceeds the frequency of the LED light source, there is a noticeable flickering effect, i.e., the strobe effect.

The LED light will flicker when switching between the ON and OFF states quickly, and whether or not it has a digital dispersion flicker depends mainly on the nature of the current supplied to it. Normally, LED lights flicker at a very high frequency that is not directly perceptible to the human eye, or is not visible to the naked eye. Because of this, any visible camera flickering is actually the normal functioning of the light, and the only thing that should be of concern is the human blink.

1. Generally, the fluorescent lamp flickers because its lamp is used for a long time, its internal resistance increases, and the voltage obtained on the starter gradually increases, when the voltage reaches the ignition voltage of the starter, the starter will flash, and its flash speed also drives the flashing of the lamp.

2. If it is caused by the breakdown of the compensating capacitor in the starter, then you can rotate the starter to pull off a paper capacitor inside it, that is, a thing next to the small bulb, and then do not short circuit the remaining wires, and install it to continue to use.

3. If it is found that the tube with the light turned off on the day is more serious in two days, it means that the service life of the lamp has arrived, and the fluorescent lamp only needs to be replaced.

4. If it is a flash, it is a broken lighter, because the start of the fluorescent lamp depends on the connection and disconnection of the bimetal sheet in the lightener to generate high pressure, so that the fluorescent lamp conducts light, and the bimetal sheet in the lightener can not be disconnected normally. The solution is to replace it with a starter.

The lamp is used in the lampshade, like the fluorescent lamp we commonly use. This lamp will inevitably flicker and flicker when it is used, which sometimes affects normal vision and lighting, and it is not good for vision. So what's the situation when the lights are flashing and flashing?

What is the problem of the light tube flashing and flashing1The light flashes due to low voltage

The rated voltage is 220V, and the low voltage is low when the voltage on the low voltage side is lower than 198V. Low voltage on the power side may cause the light to flicker. This problem can only be resolved by the grid company and can be escalated to the power department.

2.Voltage fluctuations and flickering

Voltage fluctuations and flicker refer to a series of random or periodic voltage changes in the rms value of the power frequency voltage, and the resulting lighting flicker. It is also a problem on the power side, which also needs to be solved by the power grid company.

3. There is a problem with the lamp ballast

A ballast is a device that limits the current and creates instantaneous high voltage on a fluorescent lamp. The old-fashioned long tube needs to flash a few times when the light is turned on before it can light up. The small black device that flashes on one side is the ballast.

A faulty ballast will cause the light to blink all the time, but it will not start properly, which can be solved by replacing the ballast.

4.Aging of the lamp

Eliminate the problem of power supply, modern energy-saving small lamps do not have ballasts, it may be that the lamp has been used for a long time, and the short circuit caused by poor contact or aging will make the lamp flicker, and the short circuit will flash several times to burn out the lamp. If the lamp is not burned out and has a "hissing" sound, it can be considered a lamp holder problem and the aging lamp holder needs to be replaced.

5.The lampholder is damp

If it is in the bathroom, it is easy to cause the lamp holder to be damp and short-circuit, which will eventually cause the lamp to burn out, which is more dangerous. It is recommended to do moisture-proof treatment and install moisture-proof lampshades.

Will the lamp flicker or not**

Generally, it will not **, but because of repeated starts, the power consumption is much higher than the power consumption under normal working conditions. It may be that the ballast is broken, just replace it. However, if there are signs of blackening at both ends of the lamp, it means that the lamp can no longer be used and needs to be replaced with a new one.

It may also be because the mercury vapor in the lamp is ionized at high pressure, which excites the phosphor inside the lamp to emit visible light.

What will be the case with the lamp**

If the filament is broken, the resistance of the filament must be lower than the original resistance, the filament will be melted and evaporated by a strong current, causing a sharp increase in pressure and temperature inside the bulb, which may occur**. Moreover, most of the incandescent lamps are incandescent lamps, because the inside of the bulb of the incandescent lamp is vacuum, but it is not an absolute vacuum, and there is a little gas residue, so the internal pressure of the incandescent lamp will be relatively large and low. When the filament of an incandescent lamp is energized, the temperature will be relatively high, and then a bright light will be produced.

If there is air, it will oxidize and burn out, which will affect the life expectancy. The exterior of an incandescent bulb is at atmospheric pressure. If the bulb is damaged by an external force, the air will quickly rush into the bulb and then make a ** sound.
