ABSTRACT:
An articulated operating theatre lamp has a handle (19, 20) by means of which it can be moved about several axes. The constructional elements which are movable relative to one another (11, 12, 13, 14, 15, 16) are normally secured relative to one another by means of mechanically applied but electrically releasable brakes (18) arranged in the vicinity of their hinged connections (17). Electrical switch means 21 are provided on the handle (19, 20), which actuate the electrical release mechanism (22) for the brakes (18) on being contacted by an operator and thus temporarily release the brakes during handling of the lamp (FIG. 1).
