List of light sources

This is a list of sources of light, the visible part of the electromagnetic spectrum. Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that comes from them.

Incandescence
Incandescence is the emission of light from a hot body as a result of its temperature.

 * Fractoluminescence, light generated when bonds in certain crystals are broken by fractures
 * Piezoluminescence, light produced by the action of pressure on certain solids
 * Sonoluminescence, light resulting from imploding bubbles in a liquid when excited by sound

Photoluminescence
Photoluminescence is light resulting from absorption of photons.


 * Fluorescence, the emission of light by a substance that has absorbed light or other electromagnetic radiation
 * Phosphorescence, the delayed re-emission of light by substance that has absorbed it

Radioluminescence


Radioluminescence is light resulting from bombardment by ionizing radiation.

Thermoluminescence
Thermoluminescence is light from the re-emission of absorbed energy when a substance is heated.
