    • 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.
    • 本发明涉及一种光学组件,其改进了光引擎中的多个LED光源所产生的光的颜色均匀性和改善的准直。 该光学组件专门定制以匹配组成光引擎或发光元件的固态发射器的位置。 具体而言,使用具有优化的横截面形状和微脊的成形的自由形式花键贴片内准直透镜来分散光; 使用具有优化截面形状和微凸脊的多凸角TIR准直透镜来分散和再分配相位以及提供准直; 使用具有优化表面的主混合小透镜阵列来分散来自发光器的光; 花键轮廓反射器进一步混合并准直光; 次级小透镜阵列进一步混合光; 并且第二准直透镜进一步校准光。
