Abstract

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.
