Abstract: A controllable illumination system and method comprising: (1) one or more light fixtures; (2) a controller in communication with at least some of the light fixtures; (3) a status identifier associated with at least some of the light fixtures that indicates whether the light fixture is under the influence of the controller; and (4) software in communication with the controller and the one or more light fixtures that is adapted to influence one or more light fixture characteristics, including beam direction, beam color, beam size, beam shape and intensity of beams that emanate from a light fixture.

Abstract: A room lighting system specially suited for medical procedures. The system includes first and second light assemblies adapted to be mounted in the ceiling of the procedure room and each including a lamp movable between a plurality of angular positions. The lamps are controlled by a wall control unit mounted in a wall of the procedure room or by a remote control unit including an infrared transmitter communicating with an infrared receiver mounted in the wall control unit. The light assemblies can be controlled individually as to both intensity and angular position either from the wall control unit or from the remote control unit. Each light assembly includes a transformer which receives line power and steps the line power down to a 24 volt circuit to control the intensity of the lamp and a 12 volt circuit which includes all of the controls for the light assembly.
