适用于以上的出射端可为平凸透镜设置(如图13所示)或双凸透镜设置(如图14所示)。
本发明的一种车灯用远/近光灯结构、远近光一体照明装置，
首先，通过设置的光路传输端，实现工艺要求的光型的一次性成型，省却遮光板设置、增大了光效利用率的同时，节约了空间及减少了零部件的多重装配间的累积误差；
其次，光源端通过散热器与光路传输端形成一体设置，集约了装配空间；
再次，将光路传输端的设计理念与远近光灯一体设计的理念相结合，设计出具有光路传输端的远近光一体照明装置，并且，近光灯与远光灯各自独立使用各自的光学系统，而后共用一个出光；
然后，在具体空间布设时，将近光光路传输端设置为与远光光路传输端呈间距式布设，用以避免远、近光光线相互的窜光；并在此基础上，进一步地将用以形成明暗截止光型的近光光线出射端与用以形成明暗截止光型的远光光线出射端在空间上形成重叠型布设，以使得在远近光切换时，给驾驶员提供无缝式视觉切换与平和过渡；避免由近光切换到远光后，远近光衔接处的不均匀和暗区；

同时，本案提供的一种车灯用远/近光灯结构，重点指向光效利用率及一次性成型及节约装配空间及装配工序这些考量因素；而本案提供的一种远近光一体照明装置，在满足以上考量因素的基础上，还基于车灯模组的结构关系形成因素两个方面的考量，一则将本案中的远近光光线传输过程设置为一个平行于光轴一个偏离光轴一定角度或两者均偏离光轴一定角度的方式，可产生既能既能防止远近光相互间窜光，又能与截止线处形成很好的耦合效应的效应；另则在第二近光光路传输域单独完成法规要求的近光光型的一次性成型及出射的基础上，扩展并形成通过远光光路传输端配合近光光路传输端完成法规要求的近光光型的一次性成型及出射；以此为形成不同光传输器的搭配与使用提供了拓展的友好适应，提供了器件的拓展性；
最后，本案还将光源端设置为光照度可调的形式，通过光源端的可调形成与光型适配的初级光照度响应；再结合本案设置的用以一次性成型及出射目标光型的远/近光结构，形成二级光照度适配，以形成满足光型及最大化利用光效的基础上，形成对光源端光源的极大化节约与适配性投入使用。
