Abstract
There is described an illumination unit with a planar carrier part having a plurality of light-emitting semiconductor components, in particular high-power light-emitting diodes, arranged on both sides of a main surface. On each side of the carrier part a heat sink is provided in each case. Each of the semiconductor components is connected in an efficient heat-conducting manner to a heat sink provided on an opposite side of the carrier part by way of a heat conducting means that is fed through an opening in the carrier part. At least one reflector is embodied on each heat sink having a reflective surface which concentrates the emitted light from a semiconductor component which is arranged on the side of the carrier part facing this heat sink.
