The good old light bulb of Ilyich is the favorite bomb of all Soviet schoolchildren. Everyone knows that if you break a light bulb, there will be a loud bang. But sometimes such a clap occurs in the apartment, when the light bulb explodes immediately after turning on the light. The reasons, however, are general.
An incandescent lamp is a complex device. It works by heating up as an electric current flows through a spiral of tungsten-based alloys. A typical light bulb requires at least 7 metals to make, and most modern bulbs are filled with chemically inert gases, except for low power bulbs. Such lamps (up to 25 watts) are made vacuum. The well-known explosion of a light bulb is nothing more than the stabilization of atmospheric pressure when the bulb is depressurized. Often, a sharp filling of the discharged medium of the flask with air can even lead to the destruction of its surface, which is why lamp fragments sometimes fly in all directions. Another question is why a sealed lamp filled with discharged inert gases, or even a vacuum one, suddenly depressurizes. There may be several reasons for this, but the main one is low-quality products, lamps, during the assembly of which technological errors were made. Another common problem in Russian apartments is high voltage in electrical networks. Lamp life depends on the quality of the supply voltage. As the voltage rises, the temperature of the tungsten filament rises, the tungsten atoms begin to evaporate intensively, the filament becomes thinner, the bulb darkens, and eventually the filament breaks. In this regard, it is worth paying attention to the contacts in the lamp holders, which can also shorten the life of any lamp. Finally, a banal low-quality or broken switch, poor-quality connection of the chandelier wires to the network and poor contacts in the junction boxes or apartment switchboard. If you find the problem of constant explosions of lamps in your apartment, but do not have a special education and corresponding work experience, then the work of correcting the status quo is best left on the shoulders of an electrician.
