Optical design of complex curved surfaces automotive headlamp based on light barrier with extended reflectors

  • 摘要: 挡光板是近代投射式汽车前照灯用于调节近光灯配光性能的重要部件。采用聚焦法调整挡光板拐点的位置可以有效地抑制投射式前照灯近光照射时光型截止线上的色差和梯度问题,具有提高驾驶员视觉舒适度和行车安全指标的功能。采用一种基于有延展反射面的挡光板的多曲面LED前照灯的光学设计,使用NX10.0建立结构模型,LucidShape软件进行仿真,配光屏幕最大照度值为51.9 lx。研究基于有延展反射面的挡光板的光学设计与常规挡光板的光学设计的配光差异,以及两者在吉利汽车2017年提出的近光路照标准下两者数据对比情况。结果表明:具有延展反射面的挡光板可以有效提高配光Ⅲ区各点的基础数值,进一步提高行车时道路前方40 m~50 m处的视觉亮度,利于辨清道路前方及行人情况。
    Abstract: The light barrier is an important part for the headlamp in the modern projected automobile to adjust the light distribution performance of headlights. The focus method to adjust the position of the light barrier can effectively suppress the chromatism and gradient on the cut-off line, which has the functions of improving driver’s visual comfort and driving safety. An optical design of complex curved surfaces LED automotive headlamp based on light barrier with extended reflectors was adopted, the NX10.0 was used to build the structure model and LucidShape software was used for simulation, the maximum illumination value is 51.9 lx. The light distribution differences of optical design on light barrier with extended reflectors and optical design on conventional light barrier, as well as the comparison of two data under the road lighting standard proposed by Geely Automobile in 2017 were studied. The results show that the light barrier with extended reflectors can effectively improve the basic numerical of each point in the third light distribution zone and the visual brightness at 40 m~50 m ahead of the road, which are beneficial to the road ahead and pedestrians.
