Abstract:
1. A lighting element, wherein at least one organic light-emitting diode is formed at an optically transparent substrate as a layer structure, said organic light emitting diode including electrodes having contact regions associated therewith, said at least one organic light-emitting diode and said substrate are connected to a circuit board, having electric contact elements for connecting with said electrodes of the organic light-emitting diode(s), an electric insulator extends through said circuit board and comprises a dielectric outer sleeve which surrounds a dielectric cylinder, a hollow cylindrical filler is arranged between the sleeve and the cylinder, said hollow cylindrical filler being electrically conductive and defines the electric contact elements; wherein said contact regions for the organic light-emitting diode electrodes are arranged within an active surface region of the respective organic light-emitting diode; wherein said surface of the circuit board faces in the direction of the organic light emitting diode(s) and is provided over its full surface with a metallic coating as a permeation barrier against permeation of moisture and gases, said metallic coating interrupted only by said electric insulator(s) formed about said contact elements; wherein said metallic coating forms a three-dimensionally structured surface at which at least said contact elements are designed in socket shape and an outer marginal region of the lighting element is raised; wherein said circuit board and the optically transparent substrate are connected fluid tight to one another in said outer marginal region.
