    • An optical fiber manifold is provided for coupling light from an illumination source to a plurality of spaced, large diameter output fibers, or "light pipes", which are used for a variety of purposes, such as illuminating pools, spas, hazardous material zones, jail cells, and other applications where direct lighting is dangerous, difficult to maintain, or subject to vandalism. The manifold comprises a light converging element, which may be either a lens or a reflector, for converging light separately on each of the spaced optical fibers. The light converging element is segmented, with each segment corresponding to one of the optical fibers, and is precise enough that substantially all of the convergent light is received by the respective cores of each of the spaced output fibers, thereby minimizing light loss.
    • 提供了光纤歧管,用于将来自照明源的光耦合到多个间隔的大直径输出光纤或“光导管”,其用于各种目的,例如照明池,水疗中心,危险材料区域, 监狱牢房以及其他直接照明危险,难以维护或遭受破坏行为的应用。 歧管包括聚光元件,该聚光元件可以是透镜或反射器,用于分别将光会聚在每个间隔开的光纤上。 聚光元件是分段的,每个段对应于其中一根光纤,并且足够精确,使得基本上所有的会聚光由每根间隔开的输出光纤的相应芯接收,由此使光损失最小化。
