车灯线光源设计中有关参数的计算

Calculation of the Parameters in the Linear Light Source Design of Automobile Headlights

在进行车灯线光源的优化设计时,需要计算有关的参数.在标准情形下,计算了直射光总功率与反射光总功率之比和测试屏上直射光的亮区,并绘出亮区图形;计算了测试屏上反射光(只考虑一次反射)的亮区,并绘出其图形.给出了计算过程,并用MATLAB软件计算出结果,绘出图形.

It is necessary to calculate the related parameters when carrying out optimizing design for linear light source of auto headlights. Under standard situation, this paper calculates the ratio of the total power of direct light to the total power of refracted light; calculates the bright area of direct light on the screen and draws its figure ; and calculates the bright area of refracted light on the screen and draws its figure. This paper presents the calculation process and employs MATLAB to give the conclusion and draw the figure.
