Various embodiments of the illumination unit include a surface light source, a primary optical element, a first reflector and a second reflector. The primary optical element is arranged at the surface light source in such a way that light emitted by the surface light source is imaged onto the first reflector by the primary optical element. The beam cross section of the light is reduced by the primary optical element at the same time. In this case, the first reflector images the light beam that has been reduced by means of the primary optical element onto the second reflector in order to emit the light from the second reflector from the illumination unit. |
