Abstract
A medical lighting device for illuminating an operating area has an overhead light providing axial illumination and is movably mounted over the operating area and movable manually towards or away from the operating area, and a system for assisting adjustment of a proper lighting position for the overhead light relative to the operating area in such a manner as to position the overhead light at a predetermined distance from the operating area. The system comprises a first light source for generating a first light beam and a second light source for generating a second light beam, the light sources arranged on the overhead light in angularly offset positions so that the first and second light beams converge at a point on the operating area when the predetermined distance is reached, and otherwise when not at that distance the two light beams form two light spots that are disjoint.
