Abstract
A surgical headlight that uses multiple LEDs to produce superior illumination. Heat sinks are used to help dissipate heat produced from the LEDs. The light from the LEDs is directed, using collimizers, into fiber optic cables. The fiber light from the optic cables, using an LED combiner, is then combined and focused on a working area. The LED combiner may include an adjustable lens so that the device's illumination may be focused at multiple focal distances and with varied areas of illumination. The LEDs may be powered by a battery and may comprise one or more red LEDs, one or more blue LEDs, and one or more green LEDs.
