Surgical headlight

摘要

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.

主权项

1. A surgical headlight for illuminating a surgical field, comprising:
a surgical headpiece selectively supported by the head of a user; at least two light sources supported by and attached to the headpiece and selectively actuated to emit light; at least one heat sink in thermal communication with at least one of the two light sources to receive thermal energy from the at least one of the two light sources and dissipate at least a portion of the thermal energy received; a combiner including a scrambler in optical communication with the at least two light sources to receive at least a portion of the light emitted from each of the light sources and output substantially-uniform combined light with substantially-uniform intensity and color distribution; and, a lens receiving the substantially-uniform combined light and projecting the substantially-uniform combined light into the surgical field.
