The invention provides a multiplicity of light sources—such as a planar array of LEDs—and a corresponding multiplicity of primary optic lenses, the primary optic lenses being curved and positioned to narrow a source light beam emitted from each of the light sources, and a beam shaper—which could be a beam shaping micro-refractive film or films, or a segmented refractor lens with multiple facets—that is shaped and positioned to receive a light source distribution emitted from the multiplicity of primary optic lenses and to emit an output light path having an angle of distribution different than a corresponding angle of the light source distribution.
