incandescent lamp

(General Physics) a source of light that contains a heated solid, such as an electrically heated filament

in′candes′cent lamp′

a lamp in which a tungsten filament enclosed within an evacuated glass bulb glows as an electric current passes through it.

incandescent lamp

in·can·des·cent lamp

A lamp that produces light by heating up a filament of wire inside a bulb with an electric current. Because the filament, usually made of tungsten, would burn from the heat, the bulb is filled with a nonreactive gas, such as argon, which protects the wire from burning. Compare fluorescent lamp.
