Light bulbs seem very complex. It is hard to understand how they work and why they work.
In fact, light bulbs have a very simple structure attached to their design. At the base of a light bulb they have two metal contacts which connect together the ends of an electrical circuit, which is a continuously flow of constant energy when the light is turned on.
Energy from an electrical circuit stops when the light is turned off. The connectors are attached to two stiff wires, which attach to a thin metal filament. It sits in the middle of the bulb and is held up by a glass attachment.
When the bulb is hooked up directly to a power supply, you will have an electrical current that flows from one contact to another - the wires and metal attachments.
The electric current is a solid conductor - a mass movement of electrons. The electrons bump into atoms, which create heat for the atom. This heat causes an impact allowing it to vibrate the atom creating light.
