of light by a substance not resulting from
heat; or "cold light". ... It can be caused by
chemical reactions, electrical energy,
subatomic motions or stress on a crystal.
→The definition of luminous is giving
off a very bright light or a person or
trait considered glowing. An example
of luminous is the sun. An example of
luminous is the smile of a beautiful girl.

which convert an incident energy input
into the emission of electromagnetic
waves in the ultraviolet (UV), visible or
infrared regions of the spectrum, over
and above that due to black-body emission.
