摘要
针对 2 0 0 2年全国大学生数学建模竞赛 A题推导了车灯线光源经一次反射至测试点时相应的反射曲线应满足的方程和计算反射的能量需要的积分上下限的确定方法 ,进而计算了测试点上的光照度值并求得满足设计规范的灯丝长度为 4.1 5 mm.对计算精度作了深入分析 ,因而得出计算结果正确的结论 .
A method is given in this paper to solve the design optimization of a line source headlight, the problem A in CUMCM 2002. Based on Optics, the illuminance integration at the test point is deducted. The limits of the integration and the equation that controls the reflection are obtained. The optimal light length of 4 15mm is achieved. A detailed discussion on the precision showed the correctness of the result.
