Abstract: In order to develop a lighting apparatus having a light source unit which has at least one light source and a first reflector, and having at least one optical element, with the light which is emitted from the light source being focused by the first reflector to form a light beam which can be influenced by the optical element further, in such a manner that the type of structure, in particular the diameter of the light outlet openings of the lamp housing, does not restrict the optical elements which can be used, said apparatus has a reflector unit having a second reflector and having a concave third reflector, with the concave third reflector having an opening for the light beam and the light beam being reflected by the second reflector onto the third reflector, and with the optical element being arranged between the light source unit and the reflector unit.

Abstract: Effect wheel rotation system, having a base and at least one effect wheel which is coupled thereto and can be rotated about an axis of rotation by means of a drive, the axis of rotation being arranged offset with respect to an optical axis and the effect wheel having at least one optical element which can be rotated into the region of the optical axis, in which system the effect wheel, independently of a rotation about the axis of rotation, can also be rotated about the optical axis.
