Abstract
An optical element for influencing a light emitted by a light source, having a front side facing away from and a rear side facing the light source. A recess for the input of the light is formed on the rear side, and a deflecting surface region is formed. On the front side, a frontside surface region is formed. First light beams (L1) entering the optical element via the recess, are totally reflected at the deflecting surface region and exit the optical element via the front-side surface region. The front-side surface region causes the second light beams (L2) of the light, which enter the optical element via the recess and then hit the front-side surface region directly, to undergo total reflection. High intensity light beams from the light source can be distributed onto a larger region reducing the maximum luminance of the light emitted via the front-side surface region.
