| 摘 要： | 随着现代汽车车灯设计的发展,传统的车灯配光镜由于其设计繁琐,光能利用率较低,且影响汽车美观等缺点,现已逐渐被自由曲面的车灯产品所替代。从汽车前照近光灯国标GB4599-2007出发,在已知光源属性的前提下,利用RefCAD和LightTools设计了一款适用于H7卤素灯的自由曲面反射器,经过对各测试点、区域的照度值的分析,较好地符合了GB4599-2007对近光的要求。该方法能够大大缩短车灯设计周期,为未来大功率LED用于车灯设计提供参考。

| Abstract: | With the development of the modern automotive headlight, the traditional lens headlamp is now gradually being eliminated, because the design is complicated, inefficiency and the impact of the automotive appearance. The freeform reflector becomes the predominant designation. Based on the GB4599-2007 regulation, on this premise of getting the light source properties, a freeform reflector for H7 halogen is designed using RefCAD and LightTools. After analysis of the illumination values for each test point and region, the results show that the illumination distributions meet requirements of GB4599-2007 regulation for dipped headlight. The method can greatly shorten the headlight design cycle and provide a reference for powerful LED used in headlamp design. |
