| 摘 要： | 通过合理的假设与推导，将汽车车灯线光源的直射光与反射光的总功率之比近似地转化为两部分球冠面积之比；并证明出：任一点光源发出的光线经过灯口投影到测试屏上的亮区是半径相等，圆心在同一直线上的圆．问题三是较为复杂的空间反射问题，采用两种不同方法：近似方法与计算机模拟描点法，得出反射光在测试屏上的亮区.

| Abstract: | By reasonable hypothesis and deduction, the power ratio of straight light to reflect light from linear vehicle light source is approximately converted to the area ratio of the spherical crown in this article by the author. Secondly, it is proved by geometry that light from any light source projects on the screen a bright area which is a circle with equal radius and the center in a line. The third is about more complicated reflection of space, by using two different methods-approximate and imitative drawing in computer. Thus the bright area of reflect light on the screen is got in this model. |
