Abstract:
A lens section, the lens section being adapted for use in a circumscribing ray route lens system configured to redirect and condense incident light, the lens system comprising a plurality of lens sections joined together in a side-by-side manner, the lens section comprising:a ray receiver surface convex in shape adapted to receive incident light;a transmitted light emitter surface for emitting transmitted light; anda total reflection surface disposed between the ray receiver surface and the transmitted light emitter surface for transmitting the incident light within a first fixed region of incidence angle by total reflection,wherein the transmitted light emitter surface includes a first concave emitter section and a second concave emitter section, the first concave emitter section being adapted to emit light incident on the lens system from within the first fixed region of angles, and the second concave emitter section being adapted to emit light incident on the lens system from within a second fixed region of incident angles.
