Abstract

Surgical operating room lamp comprising a lamp housing (10) and at least three reflectors (24, 26, 28) with bulbs or similar lamps provided in the housing and equally spaced around the center optical axis of the lamp housing. According to the invention all reflectors are carried by a flexible diaphragm member (16) which rests at its edge against an abutment shoulder (14) in the housing. The center of the diaphragm member is axially movable by means of a control member (18, 20, 22) to be flexed so as to adjust the angular position of the reflectors simultaneously.
