Abstract

A mixed light source has a first semiconductor component, which is provided for generating a first radiation fraction, and a second semiconductor component, which is provided for generating radiation of a second radiation fraction different from the first radiation fraction. The first semiconductor component is mounted by a first mounting point on a first heat sink with a first thermal resistance R1. The second semiconductor component is mounted by a second mounting point on a second heat sink with a second thermal resistance R2. The thermal resistances R1 and R2 are different from one another.
