A surgical light head and proximity detection method includes a housing, a plurality of light emitting elements arranged in the housing and configured to direct light at a target region of interest, and a plurality of distance sensors arranged in the housing. At least two of the distance sensors have field of views that overlap to define a common detection region of interest and the common detection region of interest at least partially overlaps with the target region of interest. The light head may have a plurality of integrally formed tilted seats that position the distance sensors relative to a center line of focus of the surgical light head. The distance sensors may be integrated in the housing via an optical component that is sealed relative to the housing and covers the distance sensor while enabling transmission and receipt of distance sensing signals therethrough.

Proximity detection for a surgical light

A light head for a medical device support system. The light head includes first and second zones of light sources, an optical system, and a control system. The first and second zones of light sources emit respective first and second beams of light that form an illumination pattern having a pattern size at a region of interest. The optical system adjusts a beam spread of the second beam of light to change the pattern size of the illumination pattern from a first pattern size to a second pattern size. The control system varies power to the first and second zones of light sources in response to adjustment of the beam spread of the second beam of light to maintain a substantially constant magnitude of illuminance at the region of interest as the pattern size is changed from the first pattern size to the second pattern size.

A method and apparatus for improving the optical properties of an LED using a retroreflector element. A light emitting apparatus includes a substrate, at least one light emitting device attached to the substrate and including an outer primary light emitting surface through which substantially all light is emitted, and a retroreflector assembly attached to the substrate. The retroreflector assembly includes a proximal surface adjacent to the substrate, a distal surface spaced away from the substrate, and a retroreflective portion arranged between proximal surface and the distal surface. A distance from the distal surface to the substrate is less than or equal to a distance from the outer primary light emitting surface to the substrate.

An aiming and status indicator system for surgical lightheads, cameras, and other lighting system accessory devices. The system includes a plurality of marker lights mounted to a housing for the accessory device. Each marker light produces a respective marker light beam that is directed towards a work area (surgical site) to provide a marker indicator pattern. The marker indicator patterns can be used to indicate the boresight of a lighthead or camera, whether a lighthead is in a focused or unfocused condition, and status information associated with the lighting system.

An adaptive shadow control system that compensates for blockage of one lighthead of a surgical lighting system by increasing the light output from one or more other lightheads of the lighting system. The system also includes control logic for automatic enablement/disablement of adaptive shadow control by detecting whether there is blockage of a lighthead and whether the respective light beams of a plurality of lightheads are being aggregated to form a single aggregated co-illumination light pattern at a work area.

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.

Surgical lighting control and video system

A medical suspension system () includes a ceiling plate () configured for mounting to a support structure (). The ceiling plate supports a device (), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm () and a spindle (), which is centrally mounted to the ceiling plate. A second device () is mounted to the ceiling plate, not through the spindle (), in the conventional manner, but via an adapter plate (), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.

A lighting system () suited to use in an operating theater includes one or more lightheads (), and an ambient lighting system () having one or more light emitting components (). The light emitting components are mounted within a canopy assembly () of the lighthead and arranged around a central support hub () to provide even illumination throughout the room. The canopy assembly includes a canopy and a canopy extension ('), which is removably mounted to the canopy, allowing the ambient lighting system to be retrofitted to an existing lighting system.

Ambient lighting system for surgical lights

A lighting system () suited to use in an operating theater includes one or more lightheads, each having a housing () and a bezel () extending therefrom. A light source () is disposed within the housing. A handle () extends below the bezel and is rotatable relative thereto. A lighting control input means (), associated with the bezel allows adjustment of the intensity of light emitted by the light source. A sterile cover () can be placed over both the handle and the bevel, allowing the input means to be manipulated by pressure on the cover with the thumb of the operator's hand, while simultaneously grasping the handle in the palm and fingers.
