Claim 11:
12. A lighting system comprising:
a light source; and
a light transmissive structure spaced from the light source, the light transmissive structure comprising:
a light transmissive substrate having a first face facing the light source and a second face on an opposite side of the light transmissive substrate as the first face, and
an array of microprism elements on the first face, each microprism element comprising a first inclined surface disposed at a first inclined angle relative to the second face, and a second inclined surface disposed at a second inclined angle relative to the second face, the first inclined angle being less than the second inclined angle, the second inclined surface having a convex curvature when viewed from angles perpendicular thereto, and at least two adjacent microprism elements having the same first inclined angle relative to the second face and the same inclined angle relative to the second face,
wherein the light transmissive structure is configured to receive light emitted from the light source in a first direction and redistribute light emerging from the second face in a second direction different from the first direction.
