Claim 6

The system of claim 4 and further including means for slewing said collector device and said convex mirror so as to follow the sun.

Claim 7

The system of claim 4 wherein the means for supporting said one end of the fiber optical line means comprises a ring-shaped holder which holds said one end of said line means and means for attaching said holder to said collector device.

Claim 8

The system of claim 6 and further including cooling fins extending outwardly from said holder.

Claim 9

The system of claim 1 wherein the means for focusing the rays of the sun comprises an optical lens.

Claim 10

The system of claim 1 wherein the means for focusing the rays of the sun comprises a parabolic reflector.

Claim 11

A lighting system employing solar light energy comprising: a collector device in the form of a dish having an aperture in the center thereof, a parabolic reflective surface on one side thereof, a fiber optical cable formed from a plurality of optical fiber lines joined together into a bundle, ring holder means for holding one end of said fiber optical bundle together, support means for supporting said collector device for rotatable movement about a predetermined axis, means for supporting said ring holder means on said collector device for movement therewith with said one end of said cable on the opposite side of said collector device and facing directly opposite said aperture, the one end of the fiber optical bundle held by the ring holder means moving along with the collector device to maintain said one end of said cable facing directly opposite said aperture, a convex mirror, means for supporting said convex mirror on said collector device on said one side thereof approximately at the parabolic focal distance from said parabolic surface, light utilization means, means for coupling the other end of said cable to said light utilization means, and means for slewing said collector device about said predetermined axis so as to maintain said collector device directed at the sun, whereby the sun's rays are focused on said convex mirror by said parabolic surface, said convex mirror directing the focused rays onto said one end of said fiber optical cable and transmitted to said light utilization means.

Claim 12
