Sandwich-like panel element

Abstract

The invention relates to a sandwich-like panel element ( 100 ) comprising at least two panels ( 102, 103 ) and a lighting device with at least one lighting means ( 106 ), said light irradiating in the front part of at least one panel ( 102, 103 ), wherein said light is at least partly deflected approximately perpendicular to said direction of irradiation and is projected over the surface of at least one of said panels, which has a transparent configuration, due to the fact that said panel acts as a light diffuser. To this end, said panel is printed, sand-radiated, etched, coated, engraved or stuck at least on one side or has a malstructure inside the panel, wherein the sandwich-like panel element ( 100 ) additionally comprises solar cell elements ( 108 ).
