Abstract:
1. A solid state light source comprising; a light pump outputting light energy; a waveguide assembly optically coupled to said light pump for receiving said light energy, said waveguide assembly having at least a core section, said wave aide assembly being elongated having a cork-screw shape extending in three-dimensions and having a decreasing bending radius; and a down-converter being made of organic photo luminescent compounds doped into an inert matrix, said down-converter converting said light energy from said waveguide assembly to a lesser light energy and outputting said lesser light energy, said down-converter coaxially extending about at least a portion of said core section of said waveguide assembly to receive said light energy and output said lesser light energy therethrough, wherein said cork-screw shape extending in three-dimensions and having said decreasing bending radius is selected to produce a generally uniform level of said lesser light energy along a length of said down-converter.
