A surgical lighting apparatus for illuminating a surgical environment includes a lighthead and a control unit. The control unit is configured to receive data from sensors positioned in one or more light emitting modules and identify, from the received data, an obstruction inhibiting delivery of a predetermined amount of light from one or more of light emitting elements of moveable light emitting modules to corresponding areas of a surgical site. The lighthead is configured to illuminate the surgical site. The lighthead includes a plurality of the light emitting modules and the sensors. Each of the light emitting modules includes a plurality of the light emitting elements positioned on a front side thereof. Each of the light emitting elements is configured to emit the predetermined amount of light from the light emitting modules to illuminate one of the corresponding areas of the surgical site.

Surgical lighting apparatus including surgical lighthead with moveable lighting modules

A lighthead identification system for controlling lightheads of a surgical lighting system. The lighthead identification system includes illuminated indicator lights that visually indicate to an operator that an associated lighthead has been selected for adjusting parameter settings on a user interface.

Lighthead identification system for lighthead control

A lighting control system suitable for a surgical lighting device. The lighting control system includes circuitry that compensates for the effects of temperature changes in a lighting device, and that compensates for forward voltage variations among LED lighting modules to provide substantially uniform light output.

A surgical light system () includes a lighthead () coupled to a suspension arm (') adapted for mounting to a surface () of a surgical room. A bulb () is disposed in the lighthead. A processor () 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 () is in operative communication with the processor () 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 () 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 () fails.
