Abstract

In various exemplary embodiments, a lighting device (100) is provided, and the lighting device (100) comprises: a substrate (130) having a carrier (102), a first electrical busbar (108-1) on or above the carrier (102); a second electrical busbar (108-2) on or above the carrier (102); an optically functional structure (104) on or above the carrier (102), wherein the optically functional structure (104) is formed between the first electrical busbar (108-1) and the second electrical busbar (108-2); and an organic functional layer structure (412) on or above the substrate (130), wherein the organic functional layer structure (412) is designed for converting an electric current into electromagnetic radiation; and a second electrode (414) on or above the organic functional layer structure (412); wherein the optically functional structure (104) is designed in such a way that the beam path of the electromagnetic radiation through the substrate (130) and / or the spectrum of the electromagnetic radiation are / is variable.

Description

technical field [0001] In various embodiments, a lighting device and a method for producing a lighting device are provided. Background technique [0002] The printing process has acquired increasing significance in the manufacture of electronic devices. In particular, the printing of substrates for organic light emitting diodes (Organic Light Emitting Diodes) (OLEDs) is an area with high potential for cost reduction and for flexible manufacturing for different OLED designs . [0003] Conventional OLED substrates have electrical busbars (busbars) and an internal coupling-out layer (internal extraction layer (IEL)) above the substrate. An anode and a cathode are formed above the substrate, with an organic functional layer system between the anode and cathode. The organic functional layer system can have: one or more emitter layers, in which electromagnetic radiation is generated; one or more charge carrier pair generating layer structures, which are composed of two respecti...
