    • A light harvesting lens module for collecting an ambient light includes a plurality of annular lenses. The annular lenses are arranged in order from center to outside to form a disc-structure. Each annular lens has a light-input curved surface and a light-output curved surface. The light-input curved surface is in opposition to the center. The light-output curved surface is in opposition to the light-input curved surface, and faces the center. The light is incident on the light-input curved surface, and is refracted and tend to concentrate by the light-input curved surface. Then, the light is emitted from the annular lens, and is refracted to the direction of the center by the light-output curved surface. The ambient light is able to be compressed into a point light by the lens module, so as to increase the concentration ratio and the compression ratio to further get the effective advantage.
    • 用于收集环境光的光收集透镜模块包括多个环形透镜。 环形透镜从中心到外侧依次布置以形成盘结构。 每个环形透镜都具有光输入曲面和光输出曲面。 光输入曲面与中心相反。 光输出曲面与光输入曲面相对,面向中心。 光入射在光输入曲面上,被折射并倾向于由光输入曲面集中。 然后,光从环形透镜发射,并被光输出曲面折射到中心的方向。 环境光能够通过透镜模块被压缩成点光,从而增加浓度比和压缩比,以进一步获得有效的优点。

    • A flexible sheet-form optical system, referenced to as a light redirecting fabric, which has a fabric-like behavior and light redirecting properties. The light redirecting fabric comprises a soft and flexible sheet of optically transmissive material, such as plasticized polyvinyl chloride. A surface of the flexible sheet includes a plurality of parallel slits having spaced-apart walls configured to reflect light by means of a total internal reflection. At least a portion of daylight incident onto the sheet is internally redirected at angles other than the angle of incidence which is exploited to enhance daylight harvesting and illumination of a building interior. Disclosed also are a method and apparatus for making the light redirecting fabric. The method includes steps of mechanical slitting of the flexible sheet with a blade, elastic stretch-elongation of the sheet along a direction perpendicular to the slits, and making at least a portion of the sheet elongation irreversible.
    • 被称为光重定向织物的柔性片状光学系统,其具有织物样行为和光重定向性质。 光重定向织物包括柔性和柔性的透光材料片,例如增塑的聚氯乙烯。 柔性片材的表面包括多个平行狭缝,其具有被配置为通过全内反射来反射光的隔开的壁。 入射到片材上的日光的至少一部分以除了被用于增强日光收获和建筑物内部照明的入射角之外的角度被内部重定向。 还公开了一种用于制造光重定向织物的方法和装置。 该方法包括以下步骤:用刀片对柔性片材进行机械切割,片材沿着与狭缝垂直的方向弹性拉伸伸长,并使片材伸长率的至少一部分不可逆。
