摘　　要：讨论了车灯设计中的光源建模的重要性,提出了灯丝发光能量分解的模型。通过分析局部灯丝发光强度的分布,运用光学理论和数学方法完成了灯丝的建模,并实现计算机的光源仿真。把光源模型应用到车灯设计的实时仿真,得到灯丝经过反射镜后的灯丝投影图和光斑等照度曲线图。最后分析了实验结果,验证了光源模型的准确性,并探讨其应用前景。This paper discussed the importance of light source model in design of automobile lamp, and proposed the light source model of filament based on energy segment. Using optics and mathematic methods the model was completed by analyzing the illuminant intensity of segmented filament. Authors de3igned software to simulating the filament light model, which show the illumination result by printing lamp projective pictures and illumination contours. So it can be applied in automobile illumination. In the last part of paper, the experiments were analyzed which verified the legitimacy of light source model. We also discussed the future applications of light source model.
