摘要
为了将光纤束端头发光应用于均匀照明场景,设计了一种基于光纤照明技术的光纤端头灯并制作了样灯模型。基于光纤导光特性设计LED光源与光纤束的耦合装置,通过公差分析得到代数多项式拟合配光曲线的最佳拟合阶次为10;并结合裁剪法设计光纤束端头的配光透镜,将光纤束与透镜进行装配得到灯具。仿真得到灯具在300 mm远接收平面上的光斑垂直照度均匀度为90.99%,水平照度均匀度为89.59%,耦合装置的耦合效率为87%。最后经过误差实验分析得到系统的最佳耦合距离为2 mm,透镜与发光端面的距离为50 mm,灯具的实际光斑照度均匀度为81.54%。理论和实验结果表明光学透镜明显改善了光纤端头光束的发散特性和均匀性,该光纤端头灯设计方案为将光纤端头发光应用于均匀照明设计提供了一种可行方案。
Abstract
To apply fiber bundle end illumination to a uniformly illuminated scene, a fiber end lamp based on fiber optic lighting technology is designed, and a principle model lamp is presented. Based on the light-guiding characteristics of the fiber, a coupling device between an LED and fiber bundle is designed. Through an error analysis, the best-fitting order of the algebraic polynomial fitting distribution curve is taken as 10, and the optical lens of the fiber bundle end is designed by the clipping method. The fiber bundle and lens are then assembled into a lamp. The simulations show that the vertical uniformity of illumination of a map placed on a receiving plane 300 mm away is 90.99%, the horizontal uniformity of illumination is 89.59%, and the coupling efficiency of the device is 87%. Finally, the error analysis shows that the best coupling distance of the system is 2 mm, the distance between the lens and light-emitting end face is 50 mm, and the uniformity of illumination of the lamp is 81.54%.The theoretical and experimental results show that the optical lens significantly improves the divergence characteristics and uniformity of the fiber end beam. The design method for the fiber end lamp provides a practicable solution for the application of fiber end illumination in uniform illumination design.
