Incandescent bulbs produce light using a property known as black body (or cavity) radiation, which simply put boils down to "hot things glow."
The incandescent bulb heats the filament (typically a coil of wire) to thousands of degrees so that it glows. Since the bulb itself is generally at most a few inches from the filament, it gets pretty hot as well.
