摘要：
A decollimator for a daylighting system includes a conical section having a circular end, a square end, and a conical shape tapering inwardly from the circular end to the square end. A mixing zone section is attached to the square end of the conical section and has a square cross sectional shape of a substantially constant cross sectional dimension. The decollimator also includes either a window with a converging Fresnel lens on the circular end of the conical section, a window with a diverging Fresnel lens on an end of the mixing zone section opposite the conical section, or both. When the conical section receives collimated light, the conical section, the mixing zone section, and the Fresnel lens together decollimate the light and provide the decollimated light out of the mixing zone section.
摘要（中）：
用于日光照明系统的拆装器包括具有圆形端部，方形端部以及从圆形端部至方形端部向内渐缩的锥形形状的圆锥形部分。 混合区段连接到圆锥形截面的正方形端，并且具有基本恒定横截面尺寸的正方形横截面形状。 分解器还包括在锥形部分的圆形端上具有会聚菲涅尔透镜的窗口，在与锥形部分相对的混合区段的端部上具有发散的菲涅尔透镜的窗口，或两者。 当锥形部分接收到准直光时，锥形部分，混合区段和菲涅耳透镜一起对光进行拆卸，并将混合区段中的去饱和光提供出去。
