Abstract
A light source 2 projects light through a lens system which, preferably, has interchangeable lenses 4, 4', 4' to a conical reflecting body 6 with a reflecting surface 5, from which the light is reflected laterally to a ring reflector 8, to be in turn reflected to an operating field 17 to be illuminated. To permit distance adjustment of the operating room light fixture with respect to the illuminated field 17, a plurality of reflecting bodies 6, 6', with respective reflecting surfaces 5, 5' of different characteristics, for example a ridge surface, concave, conical or the like, are positioned on a drum for selective placement in the beam of light 7 from the lenses. Additionally, the position of the selected reflecting bodies 6, 6' with respect to the light source can be changed by locating the reflecting body on a cam follower and positioning of a camming surface with respect thereto to change the distance between the reflecting body 6 and the light source.
