Abstract

A ring light module having a plurality of optoelectronic semiconductor components for producing electromagnetic radiation, a reflector of the ring light module comprising a reflective surface, and a support. The semiconductor components are mounted on the support. In a plan view of a main radiation side of the ring light module, the reflector comprises at most two planes of symmetry. The reflector tapers in the direction towards the main radiation side. At least some of the main emission directions of adjacent optoelectronic semiconductor components are oriented differently from each other, and the main emission directions point towards the reflective surface.
