Abstract
A fiber fed illumination system includes a solid-state light source, such as an LED; a light guide, such as a fiber optic; and a coupling assembly. The light emitting surface of the light source may be flat or concave. In the coupling assembly the light guide is placed either next to the flat surface or at the aperture of the concave surface. The light guide may be bonded directly to the light source or bonded so that index matching optical gel resides between the light emitting surface and the light guide. The coupling assembly includes a cavity surrounding the light emitting surface with a feature for retaining the light guide in proximity to the light source. The cavity is filled with index matching optical gel. The size of the light guide matches the size of the solid-state light source in order to provide the smallest feasible light guide.
