| 摘 要： | 提出一种基于自由曲面的光纤照明用耦合透镜的设计方法。通过非成像光学设计，以光学扩展量与折射定律为理论基础，自由曲面迭代优化，实现光源与光纤之间的低损耗耦合。仿真结果表明:以LED芯片作为光源，该透镜可以将光通量传导效率提高至89%以上，具有良好的应用和发展前景。

| Abstract: | A method to design coupling lens of fiber lighting based on the free-form surface is proposed. Through non-imaging optics design, based on the Etendue and the Snell's law, the iterative optimization of free-form surface is conducted, and the low-loss coupling between light source and optical fiber is realized. Simulation results show that using the LED chip as the light source, this lens can improve the flux transmission efficiency above 89% and has good applications and development prospects. |
