Claim 13:
14. An asymmetric total internal reflection (“TIR”) collimator lens comprising an elongate body formed at least in part of light transmissive material, wherein:
the elongate body is defined by a first elongate planar surface and a second elongate planar surface, the second elongate planar surface being spaced from the first elongate planar surface, wherein the first and second elongate planar surfaces at least partially define a volume of the asymmetric TIR lens; and
wherein the elongate body is further defined by a plurality of surfaces that define a channel along a further edge of the elongate body, and wherein the lens is configured to internally reflect substantially all of the light originating from a light source and passing through the plurality of surfaces that define the channel outwardly through the first elongate planar surface in the form of a substantially evenly-distributed collimated beam that is substantially fully contained within a solid angle of projection that is oriented between about 90 and about 140 degrees from nadir with respect to the light source in polar coordinates.
