Abstract:
A fiber fed illumination system comprising:a solid-state light source having a light emitting surface; a light guide, wherein said solid-state light source is bonded to said light guide; and a coupling assembly including a plastic dome with a hole, said hole being dimensioned to accept said light guide, wherein said plastic dome forms a cavity surrounding said light emitting surface, said cavity filled with an index matching optical gel, wherein said light guide is placed next to the light emitting surface of said solid-state light source, whereby light from said solid-state light source is transmitted within said light guide, wherein said solid state light source has a concave light emitting surface and the light guide is positioned relative to the concave light emitting surface such that light emitted from said concave light emitting surface is counted efficiently into the light guide, and wherein an etendue of said solid-state light source matches an etendue of said light guide.
