Incandescent Lamps are traditional light sources that produce light by heating a filament wire to a high temperature until it glows. Here is a detailed description:

How It Works:

An electric current passes through a thin tungsten filament.The filament heats up and emits visible light through a process called incandescence.The filament is encased in a glass bulb, which is often filled with inert gas (argon or nitrogen) to prevent the filament from burning out quickly.
