车灯线光源的优化设计

The Optimization Design of the Line Lamp-house of Spotlight

采用对线光源及反光面的微元分割方法建立模型,用反射光的亮点分布确定光线强度。从而建立了问题1的数学模型,对于问题2,采用与对称轴垂直的平面与抛物面的相交成的不同的反射圆,线光源上不同的点经反射圆反射到屏幕上形成不同的亮线的叠加,再对不同的反射圆叠加,从而得到了亮区。

The differentied model is given and the intensity of light is comfirmed by the brighiness of glisten. To the prochem 1 ,the mathetic model is presented. The bright zone is obtained by the search and scim-ulative methods to the problem 2.
