How does electricity produced lighting?

Different kinds of light use different mechanisms. Currently, the technologies used include incandescent lights, fluorescent lights, and LEDs.

In an incandescent light (that's the most wasteful light), a current heats up a wire, until it glows.

In a fluorescent light, the current excites atoms, i.e., it raises electrons to a higher energy level. When the electrons fall back, they emit light.

I believe LEDs work on a similar principle, i.e., exciting the atoms; however, the material is solid instead of a gas.
