| 摘 要： | 提出了一种新的、利于实施计算的实现大范围均匀照明的LED灯具透镜设计方法。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CAD软件和光学模拟软件Tracepro,模拟了自由曲面透镜的具体应用,在光源高为3m,接收面直径为10m的圆形照明区域,得到了均匀度达80%以上的照度分布,该设计可以应用在商场、工厂等室内照明灯具上。

| Abstract: | Proposed is a new and accessible method to design LED free-form lens with wide range and high uniformity illumination.Based on the energy conservation law and light refraction Snell’s law,free-form lens are calculated by the Matlab programming.CAD software is used to compose the solid model of free-form lens.With optical simulation software Tracepro,ray tracing is used to verify the secondary optical design with the height of lighting source as 3 m and the diameter of circular receiving surface as 10 m.The illumination uniformity higher than 80% is realized. |
