Abstract: A support for holding and adjusting the vertical position of medical apparatus comprises a bearing housing (10), a pivot arm (11) which is preferably vertically pivotally hinged on the bearing housing (10) and is formed to carry an electromedical apparatus, and a motor (12) for the vertical pivoting of the pivot arm (11) which is arranged on the bearing housing (10), wherein a force transmitting device (13, 14, 15, 25) is provided between the motor (12) and the pivot arm (11) which converts the rotary movement of the motor (10) into a pivotal movement of the pivot arm (11).

Abstract: An operating theatre lamp, for lighting a site of an operation from above, comprises at least one light source, followed by a reflector arrangement (3) which concentrates the light beams issuing from the light source on the site of the operation and by at least one infrared filter (41) which absorbs and/or reflects the predominant portion of the thermal radiation, and which preferably also filters out ultraviolet radiation components. The lamp further comprises at least one closure plate (5) which covers over the reflector arrangement (3) from below and is preferably made of a structured glass which irregularly refracts the light, the radiation of the light source (2) being in particular directed in a predetermined solid angle outwardly towards the reflector arrangement (3), the latter deflecting the light beams (20) downwardly onto the closure plate (5) and towards the site of the operation (7).

Abstract: An operating theatre lamp with a main reflector (13) which illuminates the area of the operation (11) with a convergent main light beam (12) and an auxiliary reflector (15) can be arranged inside the main reflector to deflect a part of the used light beam (16) at a steeper angle to the site of the operation (11).
