Abstract
Described is a light emitting diode (LED) high radiance illumination system that includes at least one LED die and a tapered collection optic. An aperture in a reflective surface at the output end of the tapered collection optic recovers light is configured to emit light to an adjacent optical fiber bundle. The reflective surface surrounding the aperture reflects light back through the tapered collection optic, resulting in increased radiance. The system provides uniform high intensity in near and far fields and is suitable for applications including surgical and microscopy illumination with high color rendering index, and stable and adjustable intensity and correlated color rendering. Illumination can include one or more colors, including white light. The system has improved thermal and optical performance and is generally more compact and lower in cost relative to conventional systems.
