Abstract:
1. An optical device for distributing the radiant emission of a light emitter comprising: a lower substantially cylindrical transfer section comprising a solid of dielectric; an upper ejector section situated upon the lower transfer section, said lower transfer section operable for placement upon the light emitter and operable to transfer the radiant emission to said upper ejector section such that the radiant emission received from the light emitter enters the lower transfer section at a first end of the lower transfer section and substantially all of the radiant emission is transferred to an opposite second end of the lower transfer section to be delivered from the second end of the lower transfer section to the upper ejector section, wherein the first end is separated from the second end by a length of the lower transfer section; and said upper ejector section shaped such that the emission is redistributed externally into a substantial solid angle, and wherein a surface of said transfer section is comprised of an array of V-grooves.
