| 摘 要： | 介绍一种新颖的白光LED聚光灯，用于聚合物光纤（POF）传光束，以得到高效率和均匀的功率耦合。采用一种椭球反射镜（反光杯），将普通T1-3／4封装的φ5mm白光LED出射光线会聚到15°角以内，可满足POF传光束的数值孔径要求。理论和实验结果表明，该光源输出光强分布均匀。

| Abstract: | A novel white LED spotlight is presented to transport light over a polymer optical fiber bundle, which has high-efficiency coupling and tmiform light distribution. By employing ellipsoidal mirror /reflector, the emergent rays from white LED with common T1-3/4 package are collected into a narrow beam of 15~, which match the numerical aperture of polymer optical fiber bundle. It is proved theoretically and experimentally that the output beam has an evenly intensity distribution. |
