incandescent bulb

A light source that is created by heating a filament until it glows within a glass chamber filled with inert gas. The incandescent concept using a platinum coil was introduced in 1820; however, the first use of the tungsten filament commonly used today was introduced in the early 1900s. See halogen bulb, fluorescent bulb, LED bulb, Acandescent bulb, tungsten and color temperature.
