Incandescent lamp, Incandescent light, {Incandescent
light bulb} (Elec.), a kind of lamp in which the light is
produced by a thin filament of conducting material, now
usually tungsten, but originally carbon, contained in a
vacuum or an atmosphere of inert gas within a glass bulb,
and heated to incandescence by an electric current. It was
inventerd by Thomas Edison, and was once called the
Edison lamp; -- called also incandescence lamp, and
glowlamp. This is one of the two most common sources of
electric light, the other being the fluorescent light,
fluorescent lamp or fluorescent bulb.
