Electricity bulbs :
As we all know an electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in AIR from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation. Incandescent bulbs are also sometimes called electric lamps, a term also applied to the original arc LAMPS.
Incandescent light bulbs are gradually being replaced in many applications by fluorescent lamps, high-intensity discharge lamps, light – emitting diodes and other devices, which give more visible light for the same amount of electrical energy input. Some jurisdictions are attempting to ban the use of incandescent light bulbs in favour of more energy-efficient LIGHTING.
Incandescent bulbs are made in a wide range of sizes and voltages, from 1.5 volts to about 300 volts. They require no external regulating EQUIPMENT and have a low manufacturing cost, and work well on either alternating current or direct current. As a result the incandescent lamp is widely used in HOUSEHOLD and commercial lighting, for portable lighting, such as table lamps, some CAR head lamps and electric flash lights, and for decorative and advertising lighting.
Some applications of the incandescent bulb make use of the heat generated, such as incubators brooding boxes for young poultry, heat lights for reptile tanks, infrared heating for industrial heating and DRYING processes, and the easy bake oven TOY. In cold weather the heat shed by incandescent lamps contributes to building heating, but in hot climates lamp losses increase the energy used by AIR CONDITIONING systems.
