Claim 16:
17. A light transmissive structure comprising:
a light transmissive substrate having first and second opposing faces; 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, wherein at least some of the microprism elements are curved and nested,
wherein the light transmissive structure is configured to receive light emitted from a light source facing the first face in a first direction and redistribute light emerging from the second face in a second direction different from the first direction.
