  • Patent number: 7490949
    Abstract: A surgical headlamp containing dual lamp housings, each containing multiple LED light sources is featured. Both lamp housings may be adjusted so that light beams emitted by each LED be selectively converged through a focusing lens at a spot a predetermined distance in front of the lamp housings. Each lamp housing typically contains in addition to the LED's, one or more focusing lenses to gather and direct the light generated by the LED's forward to an illuminated work area. Batteries, preferably rechargeable, are mounted either on the headband supporting the headlamp on a users head or external to the headband, are used to power the LED's. A cooling system for the LED's is included, which utilizes a heat sync associated with the printed circuit board for the LED's, combined with a liquid cooling solution which is pumped in chamber surrounding the base of the heat sync of the LED light system.

  • Patent number: 7425077
    Abstract: A lamp assembly adapted to cast shadow-free illumination over an area. Typically, a lamp assembly includes a plurality of light modules that are disposed in a spaced apart relationship over an area. Desirably, the lamp assembly is arranged to aim the light output of each module for overlapping summation on a target footprint. Modules generally each include a LED light source, a parabolic reflecting mirror arranged to direct light from the LED, a TIR collimating lens disposed at a distal end of the mirror, and a stray light tube disposed between the LED and a dispersing lens element.

  • Patent number: 7370991
    Abstract: The assembly includes a strap adaptable to a variety of positions. Such a strap is placed directly about the user's head. A light-emitting source spaced from the strap includes a power supply source electrically coupled to the light-emitting assembly. Such a power supply source is rechargeable. A voice-activated mechanism for biasing the light-emitting source is defined from the strap so that the light-emitting assembly can be adapted along an x-axis, y-axis and z-axis. A motor assembly is directly and operably conjoined to the voice-activated mechanism and the light-emitting assembly. The voice-activated mechanism cooperates with the light-emitting source and the motor assembly during operating conditions. Such a voice operating mechanism is power-operated. The voice-activated mechanism is conveniently responsive to a user's voice commands in such a manner that the user can selectively operate the motor assembly and the light-emitting source from a remote location.

  • Patent number: 7321385
    Abstract: 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.
