该方案实施时，因为顶部区域所对应的反射位置与近光光型底部(即最近处)是对应的(此为现有技术，原理不再赘述)，因此实现了消除车灯近光光型底部的黄色条带状区域，甚至是彩虹色条带状区域，消除了产生和主光形区域的颜色存在明显差别的不良现象。
进一步的，所述顶部区域的面积≤所在反射面面积的10％。
进一步的，所述漫反射结构为增大表面粗糙度的结构。
进一步的，所述顶部区域的宽度≤10mm。
进一步的，所述反射镜的反射面表面作镀铝处理。
进一步的，所述反射镜的材料为合金材料或塑料。
进一步的，所述顶部区域的反射面不作抛光处理，非顶部区域抛光处理。
更进一步的，所述顶部区域表面设置有斜向、横向或竖向的条纹，条纹间距≤0.1mm，条纹深度≤0.05mm。
更进一步的，所述顶部区域表面设置有规则或不规则排布的颗粒，颗粒间距≤0.05mm，颗粒大小≤0.05mm。
本发明的有益效果是：
1)将反射镜的反射面分割成两段，分成顶部区域和非顶部区域，并对顶部区域进行特殊设置，使得顶部区域的粗糙度＞非顶部区域的粗糙度，形成能够形成漫反射的结构，光线在顶部区域产生漫反射，从而达到了改 善车灯光形边界处的不良色散现象的效果。
2)使用并不复杂的反射镜优化方案，达到改善车灯模组光学性能的目的，具有很好的可操作性；对现有的零部件以及装配结构均无需做出实际改动，实施难度低，实施成本低。
