The incandescent light bulb or '''incandescent lamp''' is a source of artificial Light that works by Incandescence . An Electrical Current passes through a thin Filament , heating it and causing it to become excited, releasing Thermally Equilibrated Photons in the process. 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 called electric lamps, extending the use of a term applied to the original Arc Lamp s, and in Australia they are commonly called '''light globes''', or more commonly in other English-speaking countries '''light bulbs'''. A benefit of the incandescent bulbs is that they can be produced for a wide range of Voltage s, from just a few volts up to several hundred volts. Because of their relatively poor Luminous Efficacy , incandescent light bulbs are gradually being replaced in many applications by ( Compact ) Fluorescent Light s, High-intensity Discharge Lamp s, LED s, and other devices.
