    • An optical component called the Phase Space Combiner (PSC) is designed to join several bundles of rays. The bundles of rays, when represented in ray phase-space, occupy non- connected regions before passing through the PSC, while their representation in ray phase space occupies a single simply connected region (without holes) after passing through the PSC. Obviously, when used in reverse way it splits one bundle in several parts. We present herein the idea of using Multiple Individual Optics, MIO, not for collimating the light from the LEDs but as a PSC. Then a Single Common Optics, SCO, which can be an optical train, is used to get the desired intensity pattern. This hybrid SCO and MIO strategy combines most of the advantages of both approaches.
    • 称为相位空间组合器(PSC)的光学部件被设计成加入多束光线。 当在光线相位空间中表示时,光束束在通过PSC之前占据非连接区域,而它们在射线相空间中的表示在通过PSC之后占据单个简单连接的区域(无孔)。 显然,当以相反的方式使用时,它将一束分成几部分。 我们在这里介绍使用多个独立光学元件MIO的想法,而不是用于准直来自LED的光,而是用作PSC。 然后,可以使用可以是光学列车的单个普通光学SCO来获得所需的强度图案。 这种混合型SCO和MIO策略结合了这两种方法的大部分优点。

    • Some photovoltaic cells have a front face accepting incoming incident light and opaque gridlines overlying part of the front face, electrically bonded to the face, with upper reflective facets oblique to the plane of the front face and producing outgoing reflected light. An optical interface parallel to and in front of the front face transmits incoming light to the front face and to the gridlines and reflects back towards the front face by total internal reflection at least some of the outgoing reflected light. Some photovoltaic devices have a triple junction photovoltaic cell, a single junction photovoltaic cell, and a reflective surface arranged to distribute incoming light between the cells. The surface may be a frequency-selective mirror that apportions light so when the cells are in series the power produced, and preferably the photocurrent, is greater than if all the light fell on the triple junction cell alone.
    • 一些光伏电池具有接受入射入射光的正面和覆盖前表面的一部分的不透明网格线,电粘结到面部,具有与前表面的平面倾斜的上反射面并产生出射的反射光。 平行于前面和前面的光学接口将入射光透射到前表面和网格线,并通过至少一些输出反射光的全内反射向前表面反射。 一些光伏器件具有三结光伏电池,单结光伏电池和布置成在电池之间分配入射光的反射表面。 表面可以是分配光的频率选择镜,因此当电池串联产生的功率,并且优选地,光电流大于如果所有光都单独落在三重结电池上时。
