Abstract: The illumination body (1) has a housing (2) with a bottom element (3) and a radiation source (5) fixed on the side wall (4). Furthermore, three stationary mirrors (6, 7 and 8) are arranged in the housing (2), which mirrors serve as deflection elements for the radiation and, through reflection, effect a lengthening of the beam path (9) within the illumination body (1). Furthermore, an l-shaped radiation element (11), which can be rotated about a vertical axis (12), is seated in an opening (10) in the bottom element (3). The said radiation element essentially comprises a vertical and a horizontal tube section (13 and 14, respectively) and has, in the transition region between the two sections (13 and 14), a—preferably stationary—deflection mirror (15), which is inclined by 45° and deflects the vertically incident beam path (9) by 90° and directs it onto the directional mirror (16).

Abstract: The invention relates to a rotary device for use for lighting systems which ensure flexible and, if required, even mobile illumination of a room, for example of a television studio. The rotary device according to the invention is mounted at intersections of a transport rail system for conveying transport units, for example lamps. It has two components which can be rotated relative to one another and of which one is in the form of a pivot bearing, serving for fastening at the intersection, for the other, while the other is a rail support containing at least one rail section. According to the invention, each rail section of the rail support is provided with contact tracks so that the transport unit present on the rail section and having current collectors can obtain energy.
