    摘要: A surgical light system (10) includes a lighthead (44) coupled to a suspension arm (41′) adapted for mounting to a surface (14) of a surgical room. A bulb (130) is disposed in the lighthead. A processor (120) in the lighthead is operatively coupled with the bulb for controlling an intensity of light of the bulb and is adapted to generate a lighthead status signal representative of a first status of the lighthead. A control apparatus (32, 34) is in operative communication with the processor (120) in the lighthead. The control apparatus receives the lighthead status signal and selects a set of control algorithms from among a group of algorithms based on the lighthead status signal for controlling the lighthead. The lighthead status signal includes information regarding a size of the lighthead, an intensity of light from the bulb, a condition of the bulb, a level of current applied to the bulb, a level of current applied to the bulb, a level of voltage applied to the bulb, an internal temperature of the lighthead, and the presence of one or more of a video camera, a surgical task light, and a controllable ambient light. A human-readable display device (160) is provided for displaying information relating to the lighthead status signal. Several levels of redundancy are provided in the control system to minimize the potential loss of control due to failures. In that regard, the lightheads are operable when the control apparatus (32, 34) fails.
