An optical element is provided for beam shaping for radiation emitted by a radiation-emitting semiconductor chip. The optical element includes a radiation entrance face and a boundary surface different from the radiation entrance face with a first region and a second region. The first and second regions are arranged and embodied such that a first radiation portion of radiation entering the optical element through the radiation entrance face is reflected in the first region and after reflection in the first region is deflected in the second region towards a plane defined by the radiation entrance face.

Optical element and lighting device comprising an optical element

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 R. The second semiconductor component is mounted by a second mounting point on a second heat sink with a second thermal resistance R. The thermal resistances Rand Rare different from one another.
