再进一步的，反射部202为连续无高低落差的曲面，仅在与出光部204交接的部位具有高低落差。
更进一步的，至少其中一个辅助光型模组单元的次级光学元件2设置为平凸透镜、双凸透镜或环面透镜，透镜的焦距≤20mm，其中，环面透镜是入光面和出光面均为圆环面、且整体向出光方向隆起形状的透镜，这种透镜能够形成较宽的光形展宽，适用于大角度展宽的光形。
更进一步的，用于形成近光三区和50L光形区域的结构设置于近光的初级光学元件的反射部，其中，50L结构为凹状空腔，靠近截止部进行设置；三区结构设置于反射部中段，就有楔形结构、厚度由后向前逐渐增大，其出光面为内凹曲面，内凹指的是向后端凹。

具体实施方式
下面结合附图和具体实施例对本发明进一步说明。
本车辆照明模组可以用于近光和远光等照明，近光是车辆照明的主要功能之一，当适用于车辆照明中的近光功能时，近光模组分为多个主近光 模组和辅助近光模组，主近光一般是指对近光中间高照明强度区域进行照明的光形，辅助近光一般是指对近光两侧展宽大范围照明区域进行照明的光形，各个模组实现的近光的部分局部光形，通过各个模组光形的叠加、共同实现近光功能，以左侧车灯为例，具体实施例如下：
参见图1-2，一种车辆照明模组，包括模组单元，所述模组单元包括沿出光方向自后向前依次设置的光源1、初级光学元件2、次级光学元件3；模组单元内的光源设置为1-5个。
车辆照明模组具有至少两个模组单元：一主光型模组单元和一辅助光型模组单元；所述主光型模组单元的光型覆盖光型的核心区域，所述辅助光型模组单元的光型覆盖所述核心区域；主光型模组单元和辅助光型模组单元相互配合形成完整光型的照明系统。
本实施例中，所述主光型模组单元具有若干个，所述辅助光型模组单元具有三个；各个模组单元之间相互作用，作为一个整体能够实现照明功能；作为模组单元个体也能够单独实现部分照明的功能，和其他车辆照明模组配合使用。
下面对本实施例中各个光型模组单元分别说明：
主近光模组一：
主近光模组一设置为2个，如图1和2所示，光源和次级光学元件3的入光部均设置为1个，透镜为平凸透镜，透镜开口尺寸的高(上下方向)和宽(左右方向)尺寸均约5-20mm(优选为10mm)，光源1是单芯片的LED光源，入光部201为聚光杯状结构，通光部203的下表面设置为反射部202，反射部202设置为具有左右段差的分段面，出光部设置为半径R＝10mm的圆弧面，反射部202和出光部相交处设置为截止部205，截止部205的形状为近光截止线的具有左、右高度差的形状，用于形成具有截止线形状的主近 光光形，如图3所示。
主近光模组二：
主近光模组二设置为2个，如图4-9所示，和主近光模组一的不同之处在于：光源和次级光学元件的入光部均设置为2个，透镜开口尺寸的高(上下方向)约10mm，宽(左右方向)约15mm，光源和次级光学元件的入光部相对中轴线具有一定倾斜角度，两侧的光源和入光部倾斜指向中间，形成的光形如图11所示。
上述主近光模组一和二叠加形成的光形如图12所示。
辅助近光模组一：
辅助近光模组一设置为1个，如图13-17所示，和主近光模组一的不同之处在于：设置于通光部203下表面的反射部为不具有段差的顺滑曲面，出光部下边界的截止部205为不具有段差的连续曲线，且前视图中截止部205中间低、两侧高，高低是相对上下方向而言，用于对辅助近光进行光形调整，具有较平整的光形边界，反射部具有和截止部205相应的曲面形状，透镜为环面透镜，透镜开口尺寸的高(上下方向)约10mm，宽(左右方向)约15mm，环面透镜能够形成较大角度的展宽，由图15所示，光源和入光部设置于中轴线的左侧，根据透镜的反向原理，形成的光形位于光形中轴线的右侧，形成近光的右侧展宽光形，由图18所示，该辅助近光的光形左侧角度-20°左右，右侧+40°左右。
辅助近光模组二：
辅助近光模组二设置为1个，如图19-21所示，和辅助近光模组一的不同之处在于：光源和入光部设置于中轴线上，形成近光中间基本对称的展宽光形，由图22所示，该辅助近光的光形左右侧角度范围基本对称，约30°左右。
辅助近光模组三：
辅助近光模组三设置为1个，如图23-25所示，和辅助近光模组一的不同之处在于：光源和入光部设置于中轴线的右侧，根据透镜的反向原理，形成的光形位于光形中轴的左侧，形成近光的左侧展宽光形，由图26所示，该辅助近光的光形左侧角度-50°左右，右侧+10°左右。
图27为上述辅助近光模组一、二和三的光形叠加后的整个展宽光形，由于是左灯，则右侧(即车辆内侧)角度小于左侧(即车辆外侧)角度。
上述主近光模组和辅助近光模组共7个，可以在车灯内按照一定的排布方式进行布置，由于模组整体和透镜开口尺寸均较小，能够适应更多的车灯造型，尤其是狭窄的车灯造型，上述7个车灯模组共同用于近光的照明，图28是上述所有主近光和辅助近光模组形成的光形叠加后形成的完整近光的光形，由于等照度线的照度值设置不同，光形角度范围显示不完全一致。
上述中轴线是指过透镜焦点前后方向的轴线。
本实施例中所描述的方位关系如图4所示。
以上是本发明的优选实施例，本领域普通技术人员还可以在此基础上进行各种变换或改进，在不脱离本发明总的构思的前提下，这些变换或改进都应当属于本发明要求保护的范围之内。
