摘要： An operating room light with ceiling suspension is provided with a shaft protruding from the ceiling and containing internal electrical conductors, the shaft being enveloped in its end region by a support body provided on its outer circumference with slip rings for establishing electrical connections between the shaft and the conductors contained in a swivel arm; the swivel arm is provided with a swivel arm head as part of a rotary joint, which envelops the support body and which contains on its barrel-shaped inside slip ring pickups for making contact with the slip rings of the support body; viewed in axial direction, the support body is provided at both of its ends with bearing bushes functioning as sliding bearings, the upper bearing bush supporting an axial bearing ring that bears thereon to hold the swivel arm head; the support body together with the bearing bushes is secured against radial and axial shifting by means of threaded pins passed through openings in the pivot as well as by a locking ring held by means of annular slot in the end region of the shaft.By virtue of conical transition regions, it is possible to slip the swivel arm head with its slip ring pickups onto the support body in simple manner, thus providing advantages in particular for assembly and maintenance and for cases in which swivel arms are mounted one above the other.

摘要： A medical lamp having a reflector in the shape of an ellipsoid of rotation containing on its interior side a plurality of facets which provide for a largely shadow-free illumination of the area to be lit. An opening is provided in the reflector, which is surrounded by a ring flange. A lamp having a spiral-wound filament therein is inserted into the ring flange so that its bulb is oriented towards the surface of the reflector where the light exits, whereby the spiral-wound filament in the bulb is positioned along the reflector axis. The bulb has a base with a cylindrical portion which is adjacent to a plate flange. The cylindrical portion of the base is encircled by the ring flange of the reflector opening in such a manner that the bulb is secured against shifting in the radial direction of the reflector axis. A clip attached to opposite ends of the reflector contacts the plate flange located at the rear end of the lamp in a locking manner to secure the base to the outer edge of the ring flange and, as a result, the lamp is set in its correct spiral-wound filament position. A major advantage of the present invention is its simple construction and the speed with which the lamp can be changed.

摘要： A lamp housing for a surgical lamp having a light exit opening at one end thereof, an access opening disposed on a side opposite from the light exit opening and a cover member for closing the access opening. The cover member is attached to a pivotable spring member located in the interior of the housing. The cover member is held in the access opening through spring action by a flange-type circumferential flange on the inside of an edge surrounding the access opening. The spring member is a leaf spring connected to the cover member and is pivotably hinged to the interior of the lamp housing. By applying external pressure to the cover member, the cover member is inserted into the housing and shifted along the interior of the lamp housing by a swivel motion to the extent that access, for example, for changing the bulb, without difficulty.
