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.
