Abstract

An arrangement includes a semiconductor chip, which is designed to emit light during operation, and a cover layer, which lies across from the light-emitting surface of the semiconductor chip, such that light emitted from the semiconductor chip penetrates into the cover layer. In an area of the cover layer, overlapping with the chip, a light deflecting structure is provided by means of which light penetrating into the cover layer is deflected. The cover layer acts as an optical waveguide and is designed to emit the light such that it is distributed over the upper surface of cover layer.
