    Electroluminescent (EL) lamps are composed of two conducting surfaces (light emitted phosphor layers) with a dielectric layer between. By applying voltage to the conductive surfaces, an electric field is generated across the phosphor and dielectric layers. Thereby electrons are excited and emit light through the...
