Why do the lights keep buzzing? Is it dangerous for the lights to buzz all the time

You're talking about fluorescent lamps, if it's the fluorescent lights in your home, then it must be that this set of fluorescent lamps is made of inductive ballasts, and there is a brightener (bubble jumping), right? The advantage of the fluorescent lamp of this inductive ballast line is that the service life is longer than that of the current electronic ballast, but its disadvantage is that it is not easy to start when the road voltage is lower than 185V or when the winter is cold. Speaking of the sound problem, it may be that you have been using this set of fluorescent lamps for a long time, the inductive ballast is heated during operation, and the asphalt "encapsulated" in the ballast melts, and there is loosening around the core of the ballast, making the ballast sound when the lamp is working.

To solve this phenomenon, the best way is to change the ballast to electronic is the most trouble-free, or you have to buy a new inductor to replace it, in short, it is very time-consuming and laborious to remove and repair it yourself, it is better to replace it.

Some fluorescent lamps will make a buzzing sound after being lit, which not only affects the life of the lamp, but also makes people feel very uncomfortable. The humming sound is an electromagnetic resonance phenomenon caused by the silicon steel sheet of the fluorescent lamp's ballast not being compressed. To get rid of this noise, the way is simple:

The humming noise can be eliminated by simply opening the casing of the ballast, melting the wax and pouring it into the gap between the silicon steel sheets.

IfCeiling lampsIf the power of the ballast does not match the actual power of the lamp, then the ceiling light may buzz. In general, in this case, we only need to replace the ballast that matches the power of the lamp.

At the same time, if the ballast and the ceiling lamp are not installed tightly enough, then in the actual use process, they may form a resonance to cause the ceiling lamp to hum, this situation is relatively simple to solve, only need to install the connection between the ballast and the ceiling lamp.

If the power supply voltage is unstable, it will also cause this phenomenon, at this time you need to find a professional electrician to repair it at home, and it is likely to cause danger by yourself, which is not recommended.

There is no danger in the buzzing of the ceiling lamp, first of all, we must know that the main reason for the humming of the ceiling lamp is because the power of the ballast in your home does not match the power of the installed lamp, in addition to this reason, the unstable power supply voltage in your home will also cause the noise of the ceiling lamp.

The solution is also quite simple, we can replace the ballast of the ceiling lamp at home, and select the ballast with matching power and the lamp will not appear when installed, but if it is said that the ceiling lamp is ringing because of the unstable voltage, you can contact a professional electrician to help deal with it.

Summary. It may be a problem with the power supply circuit of the lamp, this lamp generally uses the power supply to power the LED, if the ** transformer in the power supply is not working properly, or there is a current passing through the power supply after the power supply is turned off, the AC sound will make a sound, you can change a power supply to try. Hope it helps.

The LED lights at home are always buzzing after they are turned off, what is the reason for this?

Hope it helps.

As soon as the lights are turned on, the tubes go off on the road. Are these sounds annoying and unsafe? Let's tell you that the lights are in**?

Especially in rural areas or small cities with poor economy, poor wire contact, aging lines, insufficient power supply, and too far away from low-voltage power supply will lead to low voltage and make the sunlight lamp unable to start normally. 2. Ignitor problem. The ignition device itself is of poor quality or aging, which makes the ignition voltage abnormal, resulting in the sunlight lamp not being able to start normally.

3. Lamp problem. The lamp itself is of poor quality, starting voltage or working. The base of the actuator is in poor contact, and the contact piece in the socket is not in good contact.

The 4 feet at both ends of the fluorescent lamp are not in good contact. Whether it is connected or not depends on whether the light stand is an old ballast or a new type of electronics. The general old ballast has a slight short circuit inside it, which is a capacitance error for the transistor transistor.

If you want to do it yourself, you can remove the ballast, take the shell apart, find a bit of asphalt (aka asphalt), pour it on the core, cool it down and install it again. 2. Change the ballast. The reason why the LED lights are very loud is because the current consumption of the LED lights is very low, and the influence of the line can be basically ignored.

This kind of lamp is generally powered by LED by switching power supply. If the ** transformer in the power supply does not respond often, it will make a sound, and you can change it to the power supply. Double-click the small speaker icon 2 and mute the last one to see if there is any noise3

The difference between energy-saving lamps and fluorescent lamps5

Due to fluorescent lamps.

in the ballast.

Caused by the fact that there are steel sheets on the surface of the ballast that are fixed by asphalt, and the fluorescent lamp will heat up after being used for a long time.

Melting asphalt makes the steel sheet on the ballast not firm and vibrates, if the situation is more serious, then it is recommended that the user change the ballast.

The lamp is through a lightstarter.

If the starter fails or has poor contact, the lamp will not start. The starter should be rotated first to rule out the possibility of poor contact. If it still doesn't light up, you can try to replace the starter.

First of all, the buzzing of the LED light may be a problem with the power supply circuit, such as a transformer problem, it is recommended to change the power supply; Secondly, it may be the sound emitted by the inductor, it is recommended to glue the inductor or replace the driver; Finally, it may be caused by an uneven roof or a thin bottom plate of the lamp, and it is recommended not to deform the chassis of the lamp during installation.

Hello answer, I am a car consulting without regrets. I've seen your problem. We're putting together the information for you. It takes a little time to type. Please be patient. We will reply to you within 5 minutes.

Kiss! I'm not a robot, please don't close the order, I'll be sure to get back to you as soon as possible.

If the panel lamp is used for too long, the core lamination of the ballast may be loose, or the fastening screws that hold the ballast loose, so it is easy to produce vibration sound. It is advisable to retighten the screws, soak the ballast in insulating paint and dry it, or simply replace it with a new one.

Is there anything else you would like to consult? If not, please give me a 5-star thumbs up. You can also follow me. You can always consult me if you have any questions about the car in the future. I wish you all the best in your work and a happy life, thank you.

LED fixtures are buzzing. The floor of the lamp is too thin, or the roof is uneven. The installation is that the screws are fixed too tightly, resulting in the deformation of the lamp body, so that a hollow bulge is formed in the middle of the lamp, and the LED light strip has a large power when the light is turned on, forming a magnetic field, resulting in resonance.

Solution: Install the lamp, the hole position is correct, do not let the chassis deform, just that. There is no problem with the driver and the light bar, and it can be solved by mastering certain skills when installing.

In the final analysis, it is because the picture is cheap when buying lights, and this situation mostly appears between 200-400 yuan lamps and lanterns, so it is good to pay attention to them when buying lights.
