Abstract

To permit adjustment and ready removal of a halogen lamp from an operating room light so that the halogen bulb (3) can be positioned with respect to a dome-shaped reflector (1) to control the light distribution therefrom while being readily removable for bulb replacement and cleaning, a pivot arm (5) is hinged at a circumferential point to the outer circumference of the reflector (1) and held in horizontally extended position across the reflector by a latch (16, 20; 18, 19, 19'; 21, 27). The other end of the latch is in engagement with a vertically positionable adjustment sleeve or rod (7) to adjust the position of the latch arm, and hence of the lamp bulb (3) with respect to the apex of the reflector (1) by pivoting of the pivot arm (5) about its pivot point (6) adjacent the circumference of the reflector. A plurality of such lamps may be combined in a common housing (H), and adjustment can be carried out conjointly, for example by a drive (11, 23) common to all the adjustment elements.
