Abstract:
1. An illumination unit, comprising: a planar carrier part with opposite sides, each opposite side having a main surface; a plurality of light-emitting semiconductor components arranged on the main surfaces of both opposite sides of the planar carrier part; a heat sink on each side of the carrier part, wherein the semiconductor components on one side of the carrier part are thermally connected to the heat sink on the opposite side of the carrier part; an opening in the carrier part, for a heat conducting device to provide the thermal connection; and at least one reflector on each heat sink, wherein the reflector has a reflective surface to concentrate light emitted from the semiconductor component which is arranged on this side of the carrier part facing this heat sink.
