为了实现大面积矩形均匀光斑，提出一种基于双排复眼透镜的设计方案。使用Tra-cePro软件对该照明系统方案的效果进行建模仿真，分析了复眼透镜组的间距、后工作距离等参数对光斑面积和均匀性的影响。结果表明，复眼透镜间距越小、后工作距离越大，得到的光斑面积越大；而当间距控制在微透镜焦距附近时，光斑均匀性最佳。利用该设计方案，可在1m的后工作距离得到尺寸350mm×200mm的光斑，光斑中心280mm×160mm范围内光照度均匀性＞0．85，该部分面积超过光斑整体面积的60％。该匀光方案有望在医用光疗、路灯照明等大面积均匀光照明领域得到广泛应用。

A design with two parallel fly-eye lens arrays was proposed ,in order to achieve a uni-form rectangular light spot of large area .TracePro simulation was used to analyze the impact of the parameters ,such as the space between two fly-eye lens and the back working distance of the optical system ,on the size and uniformity of the light spot .T he simulations indicates that the smaller the distance between the two lens and the longer the working distance ,the larger the formed spot size .The best uniformity of light spot is obtained when the space between the two fly-eye lens is close to the focal length of the first lens .In one design ,a spot with size 350 mm × 200 mm was obtained on the target plane ,which was 1m away from the light source . In the central region of the spot ,a range of 280 mm × 160 mm ,w hich covered more than 60%of the total area ,produced a light illumination uniformity higher than 85% .This design is ex-pected to be used in medical phototherapy ,street lighting ,and many other fields .
