Abstract

The present invention relates to an optical assembly which improves color uniformity and improved collimation of light produced by multiple LED light sources in a light engine. The optical assembly is specifically tailored to match the placement of the solid-state emitters making up the light engine or light producing element. Specifically, a shaped free-form spline patch inner collimation lens having an optimized cross-sectional shape and micro-ridges is used to disperse light; multi-lobe TIR collimation lens having an optimized cross-sectional shape and micro-ridges is used to disperse and redistribute phase as well as provide collimation; primary mixing lenslet array having an optimized surface is used to disperse light from the light emitter; a spline profile reflector further mixes and collimates the light; a secondary lenslet array further mixes the light; and a secondary collimation lens further collimates the light.
