Abstract
A beam shaping system is for example for use over an array of light sources. An array of beam shaping units is arranged in a general plane, each beam shaping unit comprising a central refracting area, an intermediate total internal reflection area for processing of light from a light source beneath the central area, and an outer total internal reflection area for processing light from the nearest light source and an adjacent light source. This outer area essentially extends the useful size of the adjacent beam shaping unit to improve the beam shaping performance and/or the optical efficiency.
