摘要
通过运用光学成像原理和空间解析几何上向量和平面的一些知识,将立体中的几何问题转化为平面几何问题来解决,对车灯线光源进行优化设计,建立模型.通过数学软件计算线光源长度,使线光源的功率最小.对得到的线光源长度,在有标尺的坐标系中画出测试屏上反射光的亮区,最后本文讨论该设计规范的合理性.
This article is focused on transforming the three dimensional geometry question to the plane geometry question and girds detailed solutions,throught the utilization optics image formation principle and the knowledge of the vector and plane of the space analytic geometry.The author puts forward an outstanding design in vehicle lamp wire photo source as well as establishes a model.The author also comes up with a way to make the power of line photo source smallest by a mathematics software used in line photo source length.Then according to the results,the author draws the bright area which is reflected on the testing screen.Finally,this article discusses the reasonability of the above-mentioned design.
