Abstract:
1. A thin-film light-emitting diode chip comprising a layer sequence having a first main emission surface and an opposite second main emission surface, so that the thin-film light-emitting diode chip has at least two opposite main emission directions, the thin-film light-emitting diode chip emitting light through the first main emission surface and through the opposite second main emission surface in said two opposite main emission directions, wherein measures for improving the outcoupling of the light generated in the layer sequence, in both of the main emission directions, are provided on both the first and the second main emission surfaces, wherein the thin-film light-emitting diode chip does not include a substrate, and wherein the first and second main emission surfaces each have an exposed portion facing in a direction away from the layer sequence so as to emit light away from the layer sequence, wherein contact areas are provided on at least one of the main emission surfaces for connecting the thin-film light-emitting diode chip, and wherein a mirror coating is provided on the side of contact areas facing the layer sequence.
