Incandescent light bulb

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.
