The word Filament itself refers to the wire or thread inside the bulb which lights up when you turn it on.

Extra explanation:

 When electric current goes through the filamentthe filament glows. It may also be known as the electron emitting element in a vacuum tube. To make the bulb produce more light,the filament is usually made of coils of thin wire, also known as the coiled coil in order to get more emmision.

Generally, Filaments in incandescent light bulbs are made of tungsten as its melting point is very high.
