摘　　要：LED作为新型的绿色光源,在道路照明领域迅速发展.道路照明要求LED路灯在路面形成均匀性良好的矩形光斑,这就需要设计自由曲面透镜来达到配光要求.简要介绍了目前常见的自由曲面透镜设计方法,并就偏微分方程法和网格法进行了详细介绍与比较,认为网格法更具有良好的研究前景.
LED, as a new type of green light source, develops rapidly in the field of road lighting. Road lighting requires that LED street lamp forms rectangular flare of good uniformity on the road, which would require the design of freeform lens to meet the requirements of light distribution. This paper briefly introduces the common design method for free-form lens, and makes a detailed introduction and comparison between the partial differential equation method and the grid method. Grid method is considered to have a good prospect of research.
