Abstract

An optical system is provided. The optical system includes a light emitting diode that generates light emissions. The optical system includes a collimator that receives the light emissions and that generates a collimated beam. The optical system includes an etendue re-shaper that splits the collimated beam into beam parts and that arranges the beam parts adjacent to each other to generate an adjacent beam part arrangement. The optical system includes micro-lens arrays that receive the adjacent beam part arrangement and that generate beams. Each of the beams includes an optimum optical efficiency or a far field intensity distribution.
