Why bulbs in the apartment are often burned out - the main reasons

Frequent failure of the lighting elements in electrical appliances should immediately alert the owners, as this canit is not safe to be. There are several reasons why the light bulbs in the apartment often burn out. Having found out what's wrong, you can solve this problem. This will help to avoid dangerous consequences and save money. Where do you start looking for a reason?

High voltage in the electrical network

If the apartment voltage is above 220 volts, the lighting spiral in the incandescent lamps is heated much more strongly, which causes intense evaporation of the tungsten from which it is made. As a result, the life of the device is greatly reduced.

Check the voltage in the apartment can be a multimeter( avometer).To get a real picture, do it several times during the day. Perhaps, the voltage rises in a certain period, for example - in the evening, if any company or organization is connected to the power grid of the house( after the end of their work).During power surges, the machine( plugs) often breaks out.

Once it is determined why the bulbs often burn out, the problem can be solved in the following ways:

1. Acquire incandescent lamps with increased operating voltage( 230-240 V).This parameter is indicated on the package and the lamp base.
2. Install an incandescent lamp protection unit for each switch. These electronic devices ensure a smooth switching on of the lighting devices and protect against surges when switched on.
3. All wiring in the apartment is connected through one or more voltage regulators. This will save not only the bulbs in the chandelier, but all electrical appliances in the house from voltage fluctuations.
4. Replace incandescent bulbs with fluorescent lamps whose service life does not change with increased voltage.
5. Use LED lighting elements.

It should be noted that knocking out plugs or machines not only during power surges, but also when the total power of the connected electrical appliances exceeds the permissible value, as well as when the wiring closes.

Faults in cartridges

If the bulbs constantly burn out only in one lamp or chandelier, and when activated periodically, characteristic buzzing or crackling is heard, and the brightness of the glow changes( light flashes), then it is necessary to check the serviceability of the cartridges.

In modern luminaires, the maximum power of incandescent lamps used is usually limited to 40 watts. This is due to the fact that most of the cartridges are made of plastic, which burns and cracks when overheated. When the contacts are loosened or burned, the lamp base will be red-hot, and it will quickly fail.

If a fault is found, clean and repair the contacts. If the plastic is burned, then such cartridges must be replaced.

Never use bulbs whose power exceeds the permissible value.

If the brightness of the lamp is not enough, then you can use fluorescent or LED lamps, which produce much more light with less energy consumption.

Broken switch

Incandescent lamps usually burn when turned on. This is explained by the current jump. If the switch contacts are faulty, or the connection of the wires under the screws is weakened, they can spark, which is equivalent to repeatedly turning on and off. It is clear that this leads to rapid wear and failure of the lighting elements. Therefore, if incandescent lamps burn continuously in electrical appliances powered from one switch, it should be checked and, if necessary, replaced.

Instead of a failed switch, it makes sense to install a dimmer. This will help to get rid of the current jump at power-up, and also will allow to adjust the brightness of light devices in the room.

Problems in connection points of apartment wiring

The reason why the light bulbs in the apartment burn out, there may be faulty apartment wiring. First of all, you should check the connection quality in the electrical panel and tighten the screws at the wire connection points. If constantly knocking out plugs or automatic machines, it is necessary to check the conformity of their power of consumed energy. Faulty and low-power need to be changed.

You can not replace the devices on the inter-apartment electrical switchboard yourself, only the electricians of the housing and communal services can perform this work.

Next, inspect the connections in the junction boxes. If wires with blackened or molten insulation are found, this means that the contacts have oxidized or weakened the contacts and need to be tightened. If the connection was twisted, then it is better to remake it by installing special connectors. Do this only on completely de-energized wiring. This is especially important if the electrical wiring in the apartment is made with aluminum wires, which are quickly oxidized in places of twisting.

It is also necessary to check and repair the connection points of the luminaires to the main electrical wiring.

When carrying out diagnostic and repair work, you should remember: in no case can not be twisted wires made of different metals. In the place of contact between aluminum and copper, a kind of "galvanic pair" is formed, which will necessarily be heated. In addition, because of the different coefficients of thermal expansion of metals, such a compound will quickly weaken. Therefore in such places it is necessary to install special pads-connectors.

Why halogen bulbs burn out

Most often halogen lamps are used in spotlights, less often - in chandeliers. One of the common reasons why such lighting elements quickly fail is the replacement of lamps with bare hands. Do it in any case impossible. Any fatty contamination of the surface causes an increase in the temperature of the bulb in this place, which leads to its destruction.

Halogen lamps should only be installed in clean gloves. If contamination is detected, the flask should be cleaned with a cloth moistened with alcohol.

Illiterate installation of wiring when installing spotlights can also cause frequent breakdown of "halogen".

Lighting of refrigerators

For illumination of cameras in a refrigerator, small-sized incandescent lamps are usually used. They automatically turn on when you open the door and turn off when you close it. Typically, the lighting elements in the refrigerator serve for a long time, but if they start to burn out repeatedly, you need to eliminate the cause.

refrigerators This could be a malfunction of the chuck contacts, the use of bulbs whose power exceeds what is technically required, or the installation of substandard lamps. First of all, it is necessary to check the connections and contacts in the chuck, if necessary replace it with a new one. You can produce such work in the refrigerator only by disconnecting it from the electrical network.

You can replace incandescent light bulbs with LEDs, which last much longer. In addition, it will help to save a little energy and improve lighting in the refrigerator.

If the apartment is constantly burning incandescent lamps, often knocking out plugs, and when you turn on the light you hear a buzzing and crackling, you need to immediately check and repair the wiring. Do this yourself, without having the relevant knowledge and experience, should not. It is better to consult specialists.
