摘要

According to the invention, a textured coupling-out layer (6) with flanks (16) is located on an upper surface. Said flanks are aligned at an angle of between 60 DEG and 88 DEG in relation to the layer plane and form the boundaries of the coupling-out regions that are offset in relation to one another and are provided for emitting the radiation. The portions of the coupling-out layer that are located in the coupling-out regions can take the form of flat truncated cones and their flanks can be fluted or serrated, in order to increase the probability that the generated radiation strikes the external limiting surface of the coupling-out layer at a steeper angle than the critical angle of the total internal reflection.
