 背景技术
随着汽车对整车灯具的外观要求越来越高，灯具的静态外观以外点亮效果也在逐步提高，而点亮效果是否均匀流畅，也决定了产品开发的是否成功。目前的车辆前部大灯的设计都在逐步趋于扁平化，设计出更加扁平化的灯具，也是造型趋势的一种，市面上车辆灯具需求的外观空间尺寸较大，尤其是传统的灯泡光源，尺寸更是LED光源尺寸1倍或者2倍之多。
 技术问题
流水转向灯功能目前逐步在市面普及，但是点亮时采用反射碗式较多，点亮效果较生硬，不够流畅。
技术解决方案
本发明的目的是提出一种集成位置灯、日行灯、流水转向灯一体的配合结构，可以减小车辆灯具所占用的Z向外观开口，达到整车需求空间极小化，同时保证优良的出光效果。

具体的说，所述折射段包括第一折射面，沿X向与所述第一折射面平行的第二折射面，以及沿Z向与第二折射面平行的第三折射面。
进一步的，所述转向灯PCB板上设有沿车辆Y向成列布置的LED，所述LED顺次分组设置，各组LED采用顺次点亮后再全部LED常亮然后全部LED熄灭的流水转向灯周期闪烁控制方式。转向灯PCB采用流水转向灯结构，结合本发明的转向灯PCB板和转向灯光学厚壁件布置形式，再通过内面罩的滤光效果，可以获得较优的流水转向灯效果。
进一步的，所述内面罩为带花纹的双色面罩，可以打散转向灯厚壁件发出的光的颗粒效果，提高流水转向灯光质量，同时双色面罩可以对灯具部件的卡接结构进行遮挡，消除外观瑕疵。
具体的说，所述集成PCB板上的LED灯采用高低功率切换的方式实现日行灯工作模式和位置灯工作模式的切换。
 有益效果
本发明的集成位置灯、日行灯、转向灯一体的配合结构，与现有技术相比，可以获得更加均匀的点亮效果；避免了传统的LED加反射镜方案带来的发光面颗粒感及传统非多功能集成一体时空间需求大的问题；出光区域和整灯外观的Z向尺寸小，为整车前脸空间造型设计留下更多的设计空间和灵活性；同时位置灯及日行灯融合了LED加光导可获得均匀的带状点亮效果，转向灯带有流水转向功能，在信号灯多功能集成设计时具备优势。
