It's called a filament wire and is usually made out of Tungsten. It has the special properties that it can be heated white hot (in a protective atmosphere9 w/o burning up. When heated that way it give of plenty of heat and quite a lot of useful light as well.
If you are talking about an incandescent light bulb then its called a filament. It is thin so that it has a high level of resistance. Current going through the filament causes it to heat up and give off EM radiation in the spectrum of visible light.

If the filament of a bulb is broken, it is referred to as a "burnt out" or "blown" bulb. This means that the filament, which is the thin wire inside the bulb that produces light when electricity passes through it, is no longer connected and the bulb cannot function properly.
The wire inside a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to produce light.
This is the part of an incandescent bulb called the filament. Incandescent bulbs are obsolescent and will probably phase out over the next few decades.

Its a coiled tungsten filament.
The thin wire inside an electric bulb is called a filament. It is usually made of tungsten and becomes hot and emits light when an electric current passes through it.
Electricity through a thin wire (filament) makes it glow, which is prevented from burning through the wire by gas inside the bulb.
The filament, located inside the light bulb, is made of a very thin wire usually made of tungsten. This filament is heated by the flow of electricity, causing it to emit light.
If you are talking about an incandescent light bulb then its called a filament. It is thin so that it has a high level of resistance. Current going through the filament causes it to heat up and give off EM radiation in the spectrum of visible light.
A light bulb filament is a thin wire, typically made of tungsten, that is heated by an electrical current to produce light. As the filament heats up, it glows and produces light, making it a critical component in an incandescent light bulb.

The wiring inside the light bulb is very thin (the filament) and glows when heated. The current through the thin wire heats up the filament wire so that it will glow. See the related link 'How Light Bulbs Work'.
