Abstract:
1. A lighting device having a plurality of light sources, wherein the lighting device comprises several superimposed layers, having a first and a second electrically conductive layer, which are configured to produce an alternating electrical field between them, an AC voltage source connected to the first and second electrically conductive layers, an electrically insulating layer between the electrically conductive layers, a first luminescent layer between the electrically conductive layers, and a second luminescent layer that is applied to the first luminescent layer and that is between the electrically conductive layers, wherein electroluminescent material is arranged in each of the first and second luminescent layers in several adjacent and spatially separated regions, each of which forms a light source, and the spatially separated regions in the first and the second luminescent layers are arranged in different planes.
