我们报道了一种新型的自由形状聚合物透镜的开发和实验分析，用于使用高亮度LED对目标区域进行均匀照明。在第一步中，LED模组被置于照明区域的中心，自由曲面透镜的两个面被设计为均匀和有效的光分布。在第二步中，系统扩展到离轴目标，减小了整体尺寸，并包含了与LED相关的自动对准结构。对每个系统进行了光度分析，结果与模拟结果非常吻合。
We report on the development and experimental analysis of novel freeform polymer lenses for the uniform illumination of a target area using high-brightness LED. In a first step, the LED module was centered over the illuminated area and the two faces of a freeform lens were designed for homogeneous and efficient light distribution. In a second step, the system was extended for an off-axis target, the overall size was reduced and structures for automated alignment with respect to the LED were included. Photometric analyses were used for each system and were found to be in good agreement with simulations.
