Abstract:
1. A solid-state light engine comprising: a lamp which includes a rod and a solid state light source, wherein in the rod includes a narrowband luminescent material, and wherein the solid state light source is adapted to emit light to excite the narrowband luminescent material such that the narrowband luminescent material emits luminescent light of a luminescent color by spontaneous emission; a first LED light module, wherein the first LED light module includes at least a first LED adapted to emit first light of a first color different than the luminescent color; a second LED light module, wherein the second LED light module includes at least a second LED adapted to emit second light of a second color different than the first color and the luminescent color; a third LED light module wherein the third LED light module includes at least a third LED adapted to emit third light of a third color different than the first color, the second color, and the luminescent color; a plurality of dichroic elements adapted to direct each of the luminescent light, the first light, the second light and the third light into an output light beam; and an optical output element adapted to couple the output light beam to an optical instrument wherein the solid state light engine is capable of emitting narrowband light exceeding 500 mW per color with intensities up to 10 W/cm 2 .
