摘　　要：基于能量守恒定理和光线折射Snell定理,通过Matlab编程计算出自由曲面透镜坐标点。借助Pro/Engineer软件和光学模拟软件Lighttools,模拟了自由曲面透镜的具体应用。本文针对LED芯片,实际设计了两种实例:LED点光源圆形光斑与矩形光斑的透镜设计,分析了不同光斑形状的透镜在设计时应注意的要点。Based on the light refraction Snell theorem and the law of conservation of energy, the tree surface coordinates were calculated by Matlab. By using Pro/Engineer and Lighttools software, the concrete applications of free surface lens were simulated. This article presents the two designs of LED chips： circular light spot lens and rectangular light spot lens of LED point light source, and discusses the key points in designing lens for different forms of light spots.
