车灯线光源设计的数学模型

The Mathematical Model of the Dengn of Car-headlamp Ray Source

从汽车头部车灯内线光源发射的光线出发,计算出直射光线总功率与反射光线总功率之比,以及直射光线与反射光在测试屏上的亮区。运用微积分、物理光学及空间解析几何知识进行计算得到形象、直观的结果,为汽车头灯设计提供了理论依据。本模型的重要结论:直射总功率与反射光总功率之比值为0.69353114;直射光的亮区面积为62549.57029(m2)。

Studies about the ray which shoots from the internal light source of the car' s headlamp,computes out the rate of the total power between the direet ray and glint ray.The bright area on the test hold of the direct ray and the glint ray.According to the demand of the problem,provide reasonable assumption and make use of the knowledge of the calus,physical optics and space analytical.geometry to proceed the argnment and get figural.audio-visual nesult.the nesult provides the theoretical basis for the design of car headlamp.The important conclusion of this model:The rate of the total power between the direct ray and glint ray is0.69353114the bright area of the direct ray is62549.57029(m 2 )
