为了更好地说明本发明提供的车灯光学组件的工作过程，以下结合该车灯光学组件在应用于照明光学装置时进行详细的介绍和说明，照明光学装置中设置有与车灯光学组件相配合的出光反射元件3和光源，光源包括与第一光学元件1对应的第一光源4和与第二光学元件2对应的的第二光源5。该照明光学装置在使用时可以将折射率较小的第一导光通道12的光线传输方向朝向出光反射元件3上的出光反射面31，折射率较大的第二导光通道22的光线传输方向朝向出光反射面31的出光光路。In order to better illustrate the working process of the vehicle light optical assembly provided by the present invention, a detailed introduction and description will be given below in conjunction with the application of the vehicle light optical assembly to a lighting optical device. The matched light-emitting reflecting element 3 and the light source include a first light source 4 corresponding to the first optical element 1 and a second light source 5 corresponding to the second optical element 2 . When the illumination optical device is in use, the light transmission direction of the first light guide channel 12 with a smaller refractive index can be directed toward the light output reflection surface 31 on the light output reflection element 3, and the light transmission direction of the second light guide channel 22 with a larger refractive index can be transmitted. The direction is toward the light exit light path of the light exit reflection surface 31 .

上述照明光学装置用于形成近光光形时的具体使用过程为：在第一光源4打开时，第一光源4发出的光线入射至第一导光通道12内并沿第一导光通道12的光线传输方向传输至分界面a处，在分界面a处由于第一导光通道12的折射率小于第二导光通道22的折射率而发生折射并进入第二导光通道22，再从第二导光通道22远离第一入光部11的侧壁折射出并照射向出光反射面31，最后经出光反射面31反射后投射形成相应的近光光形001，以用于正常车灯近光的照射；在第二光源5打开时，第二光源5发出的光线入射至第二导光通道22内并沿第二导光通道22的光线传输方向传输至分界面a处，在分 界面a处由于第二导光通道22的折射率大于第一导光通道12的折射率而被全反射后，再从第二导光通道22远离第一入光部11的侧壁折射出并照射向出光反射面31，经出光反射面31反射后出射的光线能够增强近光光形001上贴近明暗截止线区域的照明强度，以形成近光增强区域004，实现近光增强功能，进而能够在城市非高速道路、未开启车辆远光，而车辆速度又较快的情况下，提升近光远处的可视性，提高驾驶安全性。上述照明光学装置也可以用于形成具有远光增强功能的远光光形，其具体的光线传输过程与形成近光光形的过程一致，第一导光通道12和第二导光通道22与出光反射元件3的相对方位需要进行相应的调整。The specific use process of the above-mentioned illumination optical device for forming a low beam shape is: when the first light source 4 is turned on, the light emitted by the first light source 4 is incident into the first light guide channel 12 and along the first light guide channel 12.
