Abstract: A paneling apparatus for a ceiling or a wall of a room is provided, which may include: two electrically conductive conduction layers, arranged to overlap. First layers between which at least one insulation layer, which electrically insulates the conduction layers from one another, is arranged with, at least one contact-making device which, in a subregion, is accommodated in the layers and which has a first contact region. One of the conduction layers makes electrical contact, and has a second region, with which the other conduction layer makes electrical contact and is electrically insulated from the first region. The conduction layers may make electrical contact with at least one lighting element, holding the lighting element on the layers. The device is arranged on the layers and can move relative thereto.

Abstract: 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.
