Abstract

An optoelectronic semiconductor component includes a radiation emitting semiconductor chip having a radiation coupling out area. Electromagnetic radiation generated in the semiconductor chip leaves the semiconductor chip via the radiation coupling out area. A converter element is disposed downstream of the semiconductor chip at its radiation coupling out area. The converter element is configured to convert electromagnetic radiation emitted by the semiconductor chip. The converter element has a first surface facing away from the radiation coupling out area. A reflective encapsulation encapsulates the semiconductor chip and portions of the converter element at side areas in a form-fitting manner. The first surface of the converter element is free of the reflective encapsulation.
