Abstract

A lighting device may include a substrate having a carrier, a first electrical busbar, a second electrical busbar, and an optically functional structure on or above the carrier, wherein the optically functional structure is formed laterally between the first and the second electrical busbar, and a first electrode electrically coupled to the first electrical busbar and/or the second electrical busbar, on or above the carrier, and an organic functional layer structure on or above the first electrode, wherein the organic functional layer structure is formed for converting an electric current into an electromagnetic radiation, and a second electrode on or above the organic functional layer structure. The optically functional structure is formed in such a way that the beam path of the electromagnetic radiation which passes through the substrate and/or the spectrum of the electromagnetic radiation passing through the substrate are/is variable by means of the optically functional structure.
