Template:Short description 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. Script error: No such module "Labelled list hatnote".

Luminescence

Script error: No such module "Labelled list hatnote". Luminescence is emission of light by a substance not resulting from heat.

Bioluminescence

Script error: No such module "Labelled list hatnote". Bioluminescence is light resulting from biochemical reaction by a living organism.

Electric discharge (electrical energy)

Electrochemiluminescence

Script error: No such module "Labelled list hatnote". Electrochemiluminescence is light resulting from an electrochemical reaction.

Electroluminescence

Script error: No such module "Labelled list hatnote". Electroluminescence is light resulting from an electric current being passed through a substance.

Mechanoluminescence

Script error: No such module "Labelled list hatnote". Mechanoluminescence is light resulting from a mechanical action on a solid.

  • Triboluminescence, light generated when bonds in a material are broken when that material is scratched, crushed, or rubbed
  • 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

Script error: No such module "Labelled list hatnote". 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

Radioluminescent

Script error: No such module "Labelled list hatnote". Radioluminescence is light resulting from bombardment by ionizing radiation.
