  • Patent number: 7815342
    Abstract: A surgical headlamp containing lamp housings, each containing multiple LED light sources is featured wherein the LEDs cooperate together to produce a light engine. The 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 LEDs, one or more focusing lenses to gather and direct the light generated by the LEDs forward to an illuminated work area. Batteries, preferably rechargeable, are mounted in a waist pack external to the headband, and are used to poser the LEDs. A cooling system for cooling the heat generated by the LED's is provided which utilizes a swirling effect of fluid adjacent a heat sink to transfer the heat to the swirling fluid.
