Abstract:
An illumination device contains a light-emitting semiconductor chip containing a plurality of individually drivable emission regions. The illumination device furthermore contains an optical element designed to shape light emitted by the emission regions to form a beam of rays. The illumination device is designed such that different beam profiles of the beam of rays can be set by the individually drivable emission regions.
