Abstract
An operating-room light fixture features a cardanic mounting connected to an overhead beam or other stationary support by joints or linkages which rotate about horizontal and vertical axes. After setting of the optimal illumination zone into the operating plane, that zone's coordinates, and the associated coordinates of the lamp housing, are stored as values in a computer. Upon intentional or unintentional spatial displacement of the lamp housing, angle sensors in the joints, and a distance sensor in the lamp housing, furnish data to the computer, which calculates a compensating adjustment and carries it out by applying control signals to positioning motors in the cardanic mounting, until the axis or axes of the light beam(s) again place the optimal illumination zone on the operating field.
