Classification: CPC F  G | IPC F

Claim 0:
1. A luminaire comprising:
a linear light source including a row of LED elements; and
an asymmetric total internal reflection (“TIR”) 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, and the first and second elongate planar surfaces at least partially define a volume of the asymmetric TIR lens;
the elongate body is further defined by a plurality of adjacent parallel facets that cooperate to define a channel along a further edge of the elongate body
the row of LED elements is configured to direct light through the plurality of adjacent parallel facets defining the channel into the TIR lens
the lens is configured to internally reflect light entering the TIR lens through each facet of the plurality of adjacent parallel facets to create a plurality of beams, each beam in the plurality of beams corresponding to the total light entering through each respective facet, each said beam in the plurality of beams being internally reflected with the TIR lens and exiting the TIR lens through the first elongate planar surface; and
each said beam in the plurality of beams, after having exited the first elongate planar surface does not form a projection that fully overlaps with any other beam in the plurality of beams onto a surface that is spaced away and parallel to the first elongate planar surface.
