Filament.
You are thinking of a filament.
A light bulb in an electric circuit when electricity reaches it.

The function of a light bulb in an electric circuit is that it turns electrical energy into light.

It is when it is heated by electric power, when it gives off heat and light.
electrical energy ------> light & heat energy.
If you are asking about a light bulb, the threadlike conductor, often of tungsten, that is heated to incandescence by the passage of current
Osmium provides the filament for electric light and in turn gives us clear sight.
Electrical power in the form of a flow of current across a voltage difference is converted into heat energy by vibrating the electrons and atoms of the filament. Due to the heat, it gives out orange-red light. Thus it can be said that an electric toaster gives out heat energy as well as light energy.
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
