ABSTRACT:
A lamp assembly for surgery and the like includes a ceiling mounted track having opposed internal channels, a carriage assembly that rides in the track and that is connected to a depending tubular stem which terminates in a control head having a lighthead fastened to it. A switch on the control head energizes a solenoid having a movable core that acts through mechanical linkage to retract a pair of opposing brakes from engagement against the side walls of the track, thereby allowing the lamp assembly to be moved along the track easily. When the solenoid is de-energized, a compression spring urges the brakes firmly against the side walls of the track, locking the light assembly in place along the track.
