Wikipedia
Electroluminescence (EL) is an optical phenomenon and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body light emission resulting from heat ( incandescence), from a chemical reaction ( chemiluminescence), sound ( sonoluminescence), or other mechanical action ( mechanoluminescence).
