Abstract
A lighting device (10) having a plurality of light sources, which comprise several superimposed layers, has a first (18) and a second (24) electrically conductive layer, which are designed so as to create an alternating electrical field between said layers, an electrically insulating layer (20) between the electrically conductive layers (18, 24) and a luminescent layer (22) between the electrically conductive layers (18, 24), wherein electroluminescent material is arranged within the luminescent layer (22) in several spatially separated regions (30), each region forming a light source.
