If the apartment often burns out bulbs, it is urgent to understand the reasons

Frequent failure of lighting elements in electrical appliances should immediately alert the owners, as this may not be safe. There are several reasons why bulbs in an apartment often burn out. Having found out what’s the matter, we can solve this problem. This will help to avoid dangerous consequences and save finances. Where to start the search for the cause?

High voltage in the mains

If the voltage in the apartment is higher than 220 Volts, the lighting coil in incandescent lamps heats up much more, which causes intense evaporation of the tungsten from which it is made. As a result, the life of the device is greatly reduced.

You can check the voltage in the apartment with a multimeter (avometer). To get a real picture, this should be done several times during the day. Perhaps the voltage rises in a certain period, for example, in the evening, if any enterprises or organizations are connected to the power network of the house (after the end of their work). During power surges, the machine (plugs) is often knocked out.

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

1. Purchase incandescent bulbs with increased operating voltage (230-240 V). This parameter is indicated on the packaging and bulb base.
2. Install an incandescent lamp protection unit on each switch. These electronic devices ensure smooth switching on of lighting devices and protect against voltage surges when turned on.
3. Connect all electrical wiring in the apartment through one or more voltage stabilizers. This will protect not only the bulbs in the chandelier, but also all electrical appliances in the house from voltage fluctuations.
4. Replace incandescent bulbs with fluorescent ones, the service life of which does not change with increased voltage.
5. Use LED lighting elements.

You should be aware that it knocks 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 is shorted.

Cartridge malfunctions

If the bulbs constantly burn out in only one lamp or chandelier, and when turned on, a characteristic buzzing or crackling is periodically heard, and the brightness of the glow changes (the light blinks), then it is necessary to check the working condition 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 cartridges are made of plastic, which, when overheated, burns out and cracks. If the contacts are loosened or burned, the base of the bulb will become hot, and it will quickly fail.

If a malfunction is detected, it is necessary to strip and correct the contacts. If plastic is burnt, then such cartridges must be replaced.

In no case should you use bulbs whose power exceeds the allowed.

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

Broken switch

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

Instead of a failed switch, it makes sense to set a dimmer. This will help get rid of the current surge when turned on, and will also make it possible to adjust the brightness of lighting devices in the room.

Problems in the joints of the apartment wiring

The reason why the bulbs in the apartment burn out may be faulty apartment wiring. First of all, you should check the quality of the connection in the electrical panel and tighten the screws in the places where the wires are connected. If traffic jams or automatic machines are constantly knocked out, it is necessary to check the correspondence of their power to consumed energy. Faulty and low-power must be changed.

It is impossible to replace devices on the inter-apartment electrical switchboard on your own, this work can only be done by electricians from the housing and communal services.

Then you should inspect the connections in the junction boxes. If wires with blackened or molten insulation are detected, it means that the contacts have oxidized or weakened in this connection and must be tightened. If twisting was used as a connection, then it is better to redo it by installing special connectors. This should only be done on completely de-energized wiring. This is especially important if the wiring in the apartment is made of aluminum wires, which are quickly oxidized at the twisting points.

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

When conducting diagnostic and repair work, one should remember: in no case can wires connected from various metals be twisted together. In the place of contact of aluminum and copper, a kind of "galvanic pair" is formed, which will necessarily be heated. In addition, due to various coefficients of thermal expansion of metals, such a compound will quickly weaken. Therefore, in such places it is necessary to install special connector pads.

Why do halogen lamps 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. Doing this is by no means impossible. Any greasy contamination of the surface causes an increase in the temperature of the flask in this place, which leads to its destruction.

Halogen lamps

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

Illiterate wiring when installing spotlights can also be a reason for the frequent failure of the “halogen”.

Refrigerator Lighting

Small-sized incandescent lamps are usually used to illuminate cameras in a refrigerator. They automatically turn on when the door is opened and turn off when it is closed. Usually the lighting elements in the refrigerator last a long time, but if they started to burn out constantly, the cause must be eliminated.

This may be a malfunction of the contacts of the cartridge, the use of bulbs whose power exceeds technically provided, or the installation of low-quality lamps. First of all, it is necessary to check the connections and contacts in the cartridge, if necessary, replace it with a new one. It is possible to carry out such work in the refrigerator only by disconnecting it from the electric network.

You can replace incandescent lamps with LEDs, which last much longer.In addition, this will help to save a little electricity and improve lighting in the refrigerator.

If incandescent lamps constantly burn out in the apartment, traffic jams are often knocked out, and when the light is turned on, a buzzing and crackling is heard, it is urgent to check and repair the wiring. Doing this yourself, not having the appropriate knowledge and experience, should not be. It is better to contact specialists.
