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.
Claims16
An illumination device for a camera comprising a light-emitting semiconductor chip comprising a plurality of individually drivable emission regions and an optical element (15) that shapes light emitted by the emission regions to form a beam of rays, wherein different beam profiles of the beam of rays can be set by the individually drivable emission regions.
An illumination device for a camera comprising:
- a light-emitting semiconductor chip and an optical element, wherein
- the semiconductor chip has a semiconductor layer sequence containing an active zone provided to generate light and an electrical contact on the semiconductor layer sequence,
- the light-emitting semiconductor chip has a plurality of individually drivable emission regions,
- the emission regions are defined by a structuring of at least one of the electrical contact and the semiconductor layer sequence,
- the optical element shapes light emitted by the emission regions to form a beam of rays, and
- the illumination device sets different beam profiles of the beam of rays by the individually drivable emission regions.
