What Wikipedia says

Luminescence can be simply defined as any emission of visible electromagnetic radiation (light) not ascribable directly to incandescence. Incandescence emerges at high temperatures due to thermal radiation; in contrast, because luminescence is often independent of temperature, it is sometimes termed cold light.
