Light bulb

IMAGE NUMBER: P6900 LICENSE: RIGHTS MANAGED

Light bulb. Computer-enhanced colored x-ray of a light bulb. Bulbs produce light from a filament (at center), a fine tungsten wire which heats up and glows as an electric current is passed through it. Tungsten is an ideal material for a filament as it is strong and has a high melting point (3410 degrees Celsius). The interior of the bulb contains an inert gas usually a mixture of nitrogen and argon. Air cannot be used as the oxygen it contains would corrode the tungsten. Whilst in use, the tungsten filament gradually evaporates away until eventually it breaks.
