light-emitting
Giving off brightness
Light-emitting describes something that produces or gives off light.
The term appears most often in technical compounds: a light-emitting diode (LED) converts electrical current into visible light.
Light-emitting panels, screens, and organisms all generate their own illumination rather than merely reflecting it.
