此外，在现有技术中，近光III区形成结构通常设置在近光初级光学元件的下方，由于近光初级光学元件和远光初级光学元件的前端上下相衔接，使得来自近光III区形成结构的光线无法射至次级光学元件并投射至近光III区光形区域，然而，本发明创造性地将近光III区形成结构设置在次级光学元件上，使近光III区光形不会受到近光初级光学元件和远光初级光学元件之间位置关系的影响。

具体实施方式
下面结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
此外，术语“第一”、“第二”仅用于描述的目的，而不能理解为指示或暗示相对重要性或隐含指明所指示的技术特征的数量，因此，限定有“第一”、“第二”的特征可以明示或隐含地包括一个或更多个所述特征。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“设置”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或者是一体连接；可以是直接连接，也可以是通过中间媒介间接连接，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
需要理解的是，为了便于描述本发明和简化描述，术语“前、后”是指沿车辆照明方向的前后方向，例如，次级光学元件3位于前方，相对地，近光初级光学元件1位于后方，术语“左、右”是指车灯照明模组沿车辆照明方向的左右方向，术语“上、下”是指车灯照明模组沿车辆照明方向的上下方向，通常，本发明的车灯照明模组前后左右上下方向与车辆的前后左右上下方向大体一致；术语为基于附图所示的方位或位置关系，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制；而且，将车灯照明模组安装于车辆内时，可以按照水平方向、竖直方向等各种方位进行安装，对于本发明的车灯照明模组的方位术语，应当结合实际安装状态进行理解。
如图1至图39所示，本发明基本实施方式的车灯照明模组，包括光源、近光初级光学元件1、远光初级光学元件2和次级光学元件3，所述近光初级光学元件1被布置成能够引导光线依次经由该近光初级光学元件1与所述次级光学元件3出射形成近光光形，所述远光初级光学元件2包括多个准直单元21，各所述准直单元21的出光端的端面相互连接为或一体形成为远光出光面22，各所述准直单元21的入光端与所述光源一一对应，以能够使光线依次经由所述远光初级光学元件2与所述次级光学元件3出射形成远光光形。
其中，次级光学元件3通常为透镜，如平凸透镜、双凸透镜，将近光初级光学元件1与远光初级光学元件2结合，能够分别形成近光光形与远光光形，实现远近光一体功能；光线在近光初级光学元件1以及远光初级光学元件2内传播，对光源发出的光进行收集，在一定程度上，可以降低光能量的损失，提升光能的利用率；而且，不需要设置如反射镜、遮光板或电磁阀等其它零部件，便于缩小车灯照明模组的体积，利于车灯照明模组小型化设计，适应更多车灯造型的需求；远光初级光学元件2通过多个准直单元21组合的形式，形成多通道的聚光元件，能够对应形成独立的照明区域，通过光源的开闭来实现防远光炫目功能，可更加精准地对光形进行控制，以更好地满足设计需求。
本发明可以通过各种具体的近光初级光学元件1实现近光功能；具体地，如图10和图11，作为一个具体实施方式，近光初级光学元件1可以包括近光入光面12、近光导光部13和近光出光面11，形成单通道的聚光元件，近光入光面12上可以安装有多个聚光结构14，各聚光结构14成排布置，相应地，光源与各聚光结构14一一对应设置，以便通过聚光结构14对光源发出的光进行收集，这样，光线通过近光入光面12进入近光导光部13再从近光出光面11射出，通过近光初级光学元件1上设置的近光截止部15的截取，再次经过次级光学元件3射向路面形成近光光形。其中，结合图36和图37所示，近光导光部13的下表面可以为反射部19，如此，聚光结构14可以收集光源射出的光束并将其准直后射入近光导光部13，进入近光导光部13的光线一部分直接射至 近光出光面11，另一部分会射至反射部19上，反射部19可以将这些光线反射出来并再次加以利用，向前传播形成有效光，从而保证光能的利用效率。
通常，光源为多个且分散布置，之所以设置为多个、分散的光源，是因为将作为热源的光源这样设置，可以大大改善热学性能，改善模组的散热性能。
作为另一个具体实施方式，参照图31和图32，近光初级光学元件1包括第一光通道16和第二光通道17，第一光通道16与第二光通道17之间具有倾斜布置的反射面18，使近光初级光学元件1呈弯折状，反射面18的作用是对第一光通道16的光线进行全反射，以使光线被高效利用、继续在第二光通道17中进行传播，第一光通道16一端连接聚光结构14，另一端连接反射面18和第二光通道17，第二光通道17后端连接反射面18、前端设有近光出光面11，以能够使光线从所述第一光通道16内被反射到所述第二光通道17内且由该第二光通道17前端的近光出光面11出射，所述第一光通道16上的近光入光面12上安装有多个依次排布的与光源一一对应设置的聚光结构14，所述第二光通道17上设有用于形成近光光形截止线的近光截止部15。以上在表述第一光通道16时没有限定上、下关系，是因为具有弯折状的近光初级光学元件1可以向上进行弯折，也可以向下进行弯折，均能实现相应的技术效果。需要说明的是，本技术领域的技术人员也可以将近光初级光学元件1设置为只有一个第二光通道17前后布置的形式，而不将其进行弯折设置第一光通道16，这样做也能实现近光功能，但是，这样做的缺点是车灯照明模组的前后方向上的尺寸不能进一步减小；也就是说，上述技术方案将近光初级光学元件1设置为弯折状，这样使得车灯照明模组在前后方向的尺寸进一步减小，能够具有更加小型化的特点；作为优选的方案，如图31和32所示，第一光通道16自下而上延伸，第二光通道17自后向前延伸；第一光通道16与第二光通道17均具有一定长度的光通道，可以使光汇聚在较小角度范围内、更多的向前进行传播，使光能得到更好地利用。近光出光面11可以为弧面，且其半径为100mm，之所以设置为弧面，是因为具有弧面的出光面的光形成像更加清晰，具体地，这是因为光线在透镜焦点处不是汇聚成一个点，如果是一个点，且和透镜焦点重合的话，其成像最清晰，由于要形成具有一定形状的光形，光线是汇聚在透镜焦点附近、具有一定扩散的光线束，这些从近光初级光学元件1出射的光线束具有弧状时，其经透镜折射后的成像最清晰，所以将近光出光面11设置弧面，以使得光线从近光初级光学元件1出射时也具有弧形的汇聚状，以获得更佳的成像。
作为另一个具体实施方式，如图33至图35所示，近光初级光学元件1包括多个聚光结构14和反射部19，各聚光结构14沿反射部19后端边缘依次布置，且与光源一一对应，光源设置在使得产生的近光光束能够穿过对应的聚光结构14的位置，光源的数量可以根据不同光学性能的要求设置，共用一个近光初级光学元件1，可以节省研发和制造等成本；反射部19为板状结构，该反射部19的前端厚度不大于1mm，反射部19可以由塑料或者金属制成，其表面进行镀铝处理，进一步提高反射率，聚光结构14可以收集光源射出的光束并将其准直后射出，此时，部分光束会射至反射部19上，反射部19可以将这些光线反射出来并再次加以利用，向前传播形成有效光，从而保证光能的利用效率，而且将近光初级光学元件1设置为各聚光结构14和反射部19结合的形式，相对于单独使用反射镜所占用的空间更小；其中，反射部19沿各聚光结构14的出光方向设置于所述出光方向的下方，反射部19的前端连接有近光出光面11且形成有用于形成近光光形截止线的近光截止部15，近光出光面11可以为弧状曲面，弧状曲面能够对出射的光形进行进一步调整，以能够形成清晰的光形；原理在于：弧状曲面是与次级光学元件3的焦平面相适应的内凹曲面，所谓焦平面是指与次级光学元件3的光轴正交的平面，但是，由于场曲相差的原因，次级光学元件3的焦平面实际上是向后凹陷的曲面，这使得近光出光面11越靠近该焦平面的部位，经该部位出射的光线，其通过次级光学元件3形成的光像素就越清晰，因此，为了能够形成清晰的光形，需要将近光出光面11设计成与次级光学元件3的焦平面相同或大致相同的内凹曲面。
对于聚光结构14，通常可以采用具有凹腔的聚光杯结构，其凹腔内设有朝向光源的曲面凸起，可以通过调整凹腔侧壁的曲率以及凹腔内的曲面凸起的曲率来控制光线的出射路径，有效调整输出光形的能量分布，可调结构多、方便调节且光形控制更为精准；当然，也可以采用聚光结构14的入光部为平面、外凸曲面或内凹曲面的聚光杯结构；更好地对光线进行收集。
此外，近光出光面11可以为与次级光学元件3的焦平面相适应的内凹曲面，所谓焦平面是指与次级光学元件3的光轴正交的平面，但是，由于场曲相差的原因，次级光学元件3的焦平面实际上是向后凹陷的曲面，这使得近光出光面11越靠近该焦面的部位，经该部位出射的光线，其通过次级光学元件3形成的光像素就越清晰，因此，为了能够形成清晰的光形，需要将近光出光面11设计成与次级光学元件3的焦平面相同或大致相同的内凹曲面。同样地，也适用于远光初级光学元件2的远光出光面22，即远光出光面22也可以为与次级光学元件3的焦平面相适应的内凹曲面。
其中，远光初级光学元件2的前端的上边界与反射部19的前端接触，这样可以实现较好地近光和远光光形的紧密连接和顺滑过度；两者之间也可以设置一定的间隙，但是，远光初级光学元件2的前端的上边界与反射 部19的前端的间隔距离小于或等于2mm，以免出现近光光形和远光光形的过渡不均匀现象。近光初级光学元件1与远光初级光学元件2各自对应的光源可以分散设置且排列成一排，这样可以使热源更为分散，方便各光源之间的散热，提高车灯照明模组的散热性能，增加车灯照明模组的使用寿命。近光光形的中间位置一般要求比旁侧位置的照明强度高，中间的多芯片可以使得近光的光形更能满足该要求。
进一步地，位于中间区域的聚光结构14的尺寸大于位于两侧区域的其它聚光结构14的尺寸，以使中间区域的聚光结构14对应多芯片光源，以更好地满足中间区域照明强度高的要求。
更进一步地，近光初级光学元件1的近光出光面11下边缘与远光初级光学元件2的远光出光面22上边缘衔接，且近光初级光学元件1与远光初级光学元件2之间形成由前到后间隙逐渐增大的楔形间隙；这样可以使近光光形和远光光形紧密连接、顺滑、均匀过渡。
对于远光初级光学元件2，组成其的各准直单元21的出光端面相互连接或一体形成的远光出光面22上设有用于形成远光光形截止线的远光截止部23，如图2，近光截止部15与远光截止部23相衔接，使近光光形和远光光形紧密连接、顺滑、均匀过渡。
在具体实施例中，准直单元21包括入光端、通光部和出光端；进一步地，参照图13，位于远光初级光学元件2中间部分的准直单元21的通光部沿上下方向连接有两个入光端，这样，与上述位于中间区域的聚光结构14对应多芯片光源设计能够实现等同的功能，即光线通过该两个入光端能够将更多的光线射入到对应的通光部内，从而使远光光形中部区域的照明强度相对其它区域更高。
本发明可以通过各种具体安装结构将近光初级光学元件1与远光初级光学元件2安装在散热器6上，通常，由于光源较多采用发光芯片的形式，如LED芯片，因此，近光初级光学元件1和远光初级光学元件2与散热器6之间通常设置电路板；以下主要对实现远光初级光学元件2安装在散热器6上的限位结构进行描述，可以理解的是，通过简单的变换，利用限位结构同样可以将近光初级光学元件1安装在散热器6上。
参照图12和图23所示，为了防止窜光，保证各准直单元21对应的光形的独立性，相邻准直单元21之间形成由后至前间隙逐渐减小的夹角，同时，为了保证结构的稳定性，相邻准直单元21之间通过连接筋211相连；如果单个夹角过大，考虑累加效果，位于最边缘的准直单元21角度会很大，影响出光效率，因此，相邻准直单元21之间的夹角优选为0°～5°。
对应地，作为一个具体实施例，如图17和图18所示，限位结构包括压板41和支撑架42，支撑架42上设置有能够插入对应的相邻准直单元21之间间隙的限位件421，远光初级光学元件2被限定布置在压板41和支撑架42之间；进一步地，每个连接筋211对应两个限位件421，使连接筋211卡合于对应的两个限位件421之间，有效限制远光初级光学元件2前后方向的自由度；如图15、图18所示，压板41和支撑架42上均设有与远光初级光学元件2表面抵触的凸起43；凸起43使得压板41和支撑架42均与远光初级光学元件2表面局部接触，由于局部定位的零件在定位的地方加工精度要求高，非定位处的加工要求可降低，因此以局部接触代替整体接触，能够节约加工成本，当实际产品有定位不良的问题需要排查时，能够减小排查难度，减少不确定变量，并且方便修改、便于维护；另外，如图18所示，压板41两端还分别设置有第一卡扣44，第一卡扣44能够与支撑架42上的卡口45扣合，以能够对远光初级光学元件2的位置进行定位；参照图18，还可以在支撑架42左右两端分别设有限位凸起422，用于限制远光初级光学元件2左右移动；如图16和图20所示，各准直单元21的出光端相互连接或一体形成的结构下端延伸形成有翻边凸起24，翻边凸起24与支撑架42上的安装槽425扣合，以能够进一步对远光初级光学元件2进行定位。
作为另一个具体实施例，如图38和图39所示，所述支撑架42前后端分别设有支撑架前部定位面423和支撑架后部定位面424，支撑架前部定位面423和支撑架后部定位面424设于同一平面上，压板41前后部分别设有压板前部定位面411和压板后部定位面412，压板前部定位面411和压板后部定位面412设于同一平面上，各准直单元21的前部下面与支撑架前部定位面423贴靠，各准直单元21的后部下面与支撑架后部定位面424贴靠，压板前部定位面411与各准直单元21的前部上面贴靠，压板后部定位面412与各准直单元21的后部上面贴靠，以能够限制远光初级光学元件2上下方向的自由度。
对于上述结构设计，只对压板前部定位面411、压板后部定位面412、支撑架前部定位面423和支撑架后部定位面424这四个平面的精度有要求，对于其余部位的精度要求不高，这样的设计不仅可以简化压板41和支撑架42的制作工艺，同时也可以降低制作成本，同时，即使对这四个定位面的精度要求再高一些，也是能够实现的。各所述定位面的精度提高了，相对地，远光初级光学元件2的定位精度也就提高了，经过远光初级光学元件2的光线就能够更准确的达到预期效果，降低了零件报废率，节约了制作成本。
同样地，压板41两端还分别设置有第一卡扣44，第一卡扣44能够与支撑架42上的卡口45扣合，以能够对远光初级光学元件2的上下方向位置进行限定；而且，限位件421还可以设置为上部截面积小于下部截面积的 圆台结构或棱台结构，与相对应的相邻准直单元21之间间隙的横截面形状相适应。限位件421上小下大的结构可以使得两个限位件421之间的间隙上大下小，这样有利于所述连接筋211安装，在日常使用过程中不易发生位移，保证远光初级光学元件2的光学性能的稳定性。远光初级光学元件2作为一种聚光器，通过将各限位件421插接在对应的相邻准直单元21之间的间隙内对远光初级光学元件2的左右方向进行限位，同时连接筋211设在两排限位件421之间对远光初级光学元件2的前后方向进行限位，定位精准，有效保证了远光初级光学元件2的各准直单元21的入光端与光源之间的相对位置以及各准直单元21之间的位置关系，从而不易产生由于定位不准导致过多的光效率损失以及远光初级光学元件2变形导致的光型扭曲，另外，将传统的聚光器前后压入安装变为上下压入安装，有效减小了安装行程，更符合聚光器的结构特性，使得聚光器安装便利。
作为另一个具体实施例，如图27所示，限位结构包括压板41和支撑架42，支撑架42设有用于安装远光初级光学元件2的槽结构，远光初级光学元件2位于支撑架42和压板41之间，各准直器单元21的入光端一一对应有LED光源，压板41前后边缘各延伸出一个折边，两个折边可以分别与远光初级光学元件2前后端边缘对应的卡合在一起，能够限定远光初级光学元件2的振动及移动；槽结构后端还设有多个限位件421，各限位件421分别与对应的相邻准直单元21之间的间隙插接，能够用于限定各准直单元21之间的相对位置，保证了各准直单元21之间的相对位置关系始终一致，不会因为振动或挤压轻易的发生变形，稳定性更好；槽结构前端设有安装槽425，安装槽425能够与翻边凸起24扣合连接，定位远光初级光学元件2在支撑架42上的安装位置，使得远光初级光学元件2不会因振动发生偏移，由于远光初级光学元件2导光，部分光线也会从翻边凸起24出射，支撑架42还可以有效防止光线从翻边凸起24出射；
其中，远光初级光学元件2的远光出光面22可以为从上到下逐渐向后侧弯曲的曲面设计，在一定曲率范围内，曲率越大光线越集中，这样就有更多的光线折射到次级光学元件3，具有较高的光能利用率。
而且，除了上述第一卡扣44与卡口45扣合的连接方式，还可以采用定位孔销等其它连接方式来实现压板41和支撑架42之间的连接固定，例如，连接结构包括形成在压板41和支撑架42一者上的定位孔以及形成在另一者上的定位销，还包括压板41和支撑架42两者上的用于螺纹连接的通孔，利用螺栓穿过通孔将压板41固定在支撑架42上。
需要说明的是，初级光学元件对车灯照明效果的好坏起到了很大的作用，而初级光学元件的定位和安装可靠性对车灯光形的精度和车灯照明效果影响很大；同时，设置在初级光学元件上的任何一个部件都会对光线的初级配光产生影响，过多的安装结构和定位结构会对初级光学元件的配光效果产生或多或少的影响；为此，通过限位结构的设置，可以减少近光初级光学元件1与远光初级光学元件2上安装结构和定位结构的数量。
在具体实施例中，如图28至图30，近光初级光学元件1也可以由多个准直单元21组成，各准直单元21的入光端与光源一一对应，相邻准直单元21之间形成由后至前间隙逐渐减小的夹角，且相邻准直单元21之间通过连接筋211相连；近光初级光学元件1的各准直单元21的出光端相互连接或一体形成为近光出光面11，远光初级光学元件2的各准直单元21的出光端相互连接或一体形成为远光出光面22，且通过限位结构与散热器6连接，限位结构包括安装支架51、上限位件52和下限位件53，安装支架51上侧由下到上依次安装有近光初级光学元件1和对该近光初级光学元件1的上下方向进行限位的上限位件52，安装支架51下侧由上到下依次安装远光初级光学元件2和对该远光初级光学元件2的上下方向进行限位的下限位件53，安装支架53的上、下侧均形成有用于对近光初级光学元件1和远光初级光学元件2的水平方向进行限位的水平限位结构。
通过设置上述近光初级光学元件1和远光初级光学元件2能够形成两排光斑，近光初级光学元件1形成的一排光斑做近光随动转向使用，远光初级光学元件2形成的一排光斑做防炫目远光使用。其中，上述近光初级光学元件1和远光初级光学元件2中各准直单元21的入光端均对应一个光源，相邻准直单元21的入光端之间通过连接筋211相连；各光源发射出的光线经由对应的准直单元21的入光端进入各准直单元21，并从出光面射出，由于各准直单元21的出光端汇聚在一起，因此近光初级光学元件1和远光初级光学元件2对于各光源发出的光线起到汇聚的作用。另外，单个准直单元21整体形状类似矩形柱状结构，其中各准直单元21的出光端相互连接构成出光面，而入光端需要相互隔开防止窜光，保证各准直单元21光形的独立性，因此各准直单元21之间设计有夹角，如果单个夹角过大，考虑累加效果，位于最边缘的准直单元21角度会很大，影响出光效率，因此，相邻准直单元21之间的夹角优选为0°～5°。
上限位件52底部设有多个与近光初级光学元件1形成局部接触的上限位凸台521，下限位件53顶部设有多个与远光初级光学元件2形成局部接触的下限位凸台531，上限位件52和下限位件53分别与安装支架51螺栓连接；由于局部定位的零件在定位的地方加工精度要求高，非定位处的加工要求可降低，因此以局部接触代替整体接触，能够节约加工成本，当实际产品有定位不良的问题需要排查时，能够减小排查难度，减少不确定变量，并且修改方便、便于维护；近光初级光学元件1和远光初级光学元件2上均设有第二卡扣54，安装支架51的上、 下侧均设有与第二卡扣54相配合的卡接结构，卡接结构为卡槽或者台阶，第二卡扣54一端设有与卡槽或台阶相配合的卡钩，优选地，第二卡扣54分别设在近光初级光学元件1的出光端的两侧，以及分别设在远光初级光学元件2的出光端的两侧，将近光初级光学元件1和远光初级光学元件2的入光端分别定位安装在安装支架51的上、下侧后，再通过第二卡扣54将近光初级光学元件1和远光初级光学元件2的出光端固定在安装支架51上，从而对近光初级光学元件1和远光初级光学元件2的入光端和出光端都进行有效定位，有效保证近光初级光学元件1和远光初级光学元件2安装的精准性。
近光初级光学元件1和远光初级光学元件2可以为一种聚光器，水平限位结构均包括两排限位柱55，各所述限位柱55插接在对应的相邻所述准直单元21的入光端之间的间隙内，且相邻所述准直单元21之间的连接筋211位于两排所述限位柱55中相邻两个之间。在安装时，将近光初级光学元件1从安装支架51上方压入，使得近光初级光学元件1的相邻准直单元21的入光端之间的间隙与安装支架51上侧的各限位柱55对应，将各限位柱55插接在对应的相邻准直单元21的入光端之间的间隙内，并使得连接筋211位于两排限位柱55之间；将远光初级光学元件2从安装支架51下方压入，同样，使得远光初级光学元件2的相邻准直单元21的入光端之间的间隙与安装支架51下侧的各限位柱55对应，将各限位柱55插接在对应的相邻准直单元21的入光端之间的间隙内，并使得连接筋211位于两排限位柱55之间。
通过将各限位柱55插接在对应的相邻准直单元21的入光端之间的间隙内对近光初级光学元件1和远光初级光学元件2的左右方向进行限位，通过将连接筋211设在两排限位柱55之间对近光初级光学元件1和远光初级光学元件2的前后方向进行限位，定位精准，有效保证了近光初级光学元件1和远光初级光学元件2的各准直单元21的入光端与光源之间的相对位置以及各准直单元21之间的位置关系，从而不易产生由于定位不准导致过多的光效率损失以及近光初级光学元件1和远光初级光学元件2变形导致的光形扭曲，另外，将传统的聚光器前后压入安装变为上下压入安装，有效减小了安装行程，更符合聚光器的结构特性，使得聚光器安装便利。
准直单元21的入光端也是一种聚光装置，可以采用具有凹腔的聚光杯结构，所述凹腔内设有朝向光源的曲面凸起，可以通过调整凹腔侧壁的曲率以及凹腔内的曲面凸起的曲率来控制光线的出射路径，有效调整输出光形的能量分布，可调结构多、方便调节且光形控制更为精准；或者，准直单元21的入光端为平面、外凸曲面或内凹曲面的聚光杯结构，更好地对光线进行收集。
一般地，近光初级光学元件1和远光初级光学元件2可以为透明光学元件，例如，由透明PC聚碳酸酯、PMMA材料有机玻璃、硅胶或玻璃等透明光学元件制成。
在具体实施例中，近光初级光学元件1和远光初级光学元件2前端互相接触，且设置在次级光学元件3的透镜焦点处，以获得清晰的成像，本技术领域的技术人员也可以将出光面的前端设置为不和透镜焦点重合，以使光形稍微虚化，改善光形衔接性；优选地，近光初级光学元件1和远光初级光学元件2与次级光学元件3的焦点的最小距离≤2mm。
此外，参照图8所示，可以在次级光学元件3的出光面上设有或一体形成有网格结构，以方便调光。次级光学元件3的出光面采用网格状结构处理，网格大小约为2*1mm，可以通过调整网格大小来控制光的扩散方向，通常单个网格的面积越大光的扩散就越明显，可以根据实际需要选择合适网格面积来处理，提高出射光形的均匀性并弱化色散。而且，初级光学元件和出光面网格状结构处理的次级光学元件3结合，不仅使出射光线更多地折射到次级光学元件3，具有较高的光能利用率，而出射光线先后经过初级光学元件和次级光学元件3的出光面的网格，更好地提高出射光形的均匀性并弱化色散。
其中，网格状结构中的单个网格单元为外凸曲面、内凹曲面或平面；进一步地，当网格状结构中的单个网格单元为平面时，其形状可以是长方形、正方形、三角形、多边形或其他不规则轮廓形状。网格状结构可以为横向和纵向相交划分的网格状结构，也可以为斜向相交划分的网格状结构，但是本发明的网格状结构并不仅限于这两种，可以根据实际光形需要而定。明显地，网格状结构能够扩大照明角度以及改善光形均匀性。
现有的远近光一体模组通常将近光III区形成结构100设置在近光初级光学元件1的下方，由于近光初级光学元件1和远光初级光学元件2的前端上下相衔接，使得来自近光III区形成结构100的光线无法射至次级光学元件3并投射至近光III区光形区域；针对该技术缺陷；参照图1、图3和图9，本发明创造性地将近光Ⅲ区形成结构100设置在次级光学元件3的入光面，次级光学元件3一般为透镜。
参照图40和图41，本发明的次级光学元件3上设有或一体形成有近光Ⅲ区形成结构100，如图45和图46，该近光Ⅲ区形成结构100可以在其入光面的任意位置，近光III区形成结构100包括用于扩散光线的、凸出于次级光学元件3的入光面的多个凸起，主要用于形成近光Ⅲ区光形，并且该近光Ⅲ区光形连续均匀且其照度符合法规要求。
进一步地，如图40所示，次级光学元件3的入光面上部和中部区域31为上下方向的平面，次级光学元件 3的入光面下部区域32为由上至下向出光方向倾斜的平面，入光面下部区域32设有或一体形成有近光III区形成结构100，该近光III区形成结构100包括用于扩散光线的、凸出于入光面下部区域32的多个凸起。本发明的入光面下部区域32的多个凸起用于对光线进行扩散，以确保近光光形的III区光形连续均匀且其照度符合法规要求。
本发明的次级光学元件3的入光面上部和中部区域31为沿着上下方向设置的平面，入光面下部区域32由上至下向出光方向倾斜，这种结构可以使射入该近光III区形成结构100的光线能够被次级光学元件3的出光面折射至近光光形的III区，即折射至截止线以上。同时，将近光III区形成结构100设置在次级光学元件3的入光面下部区域32，能够使得光线经该近光III区形成结构100射入次级光学元件3，再经过次级光学元件3的出光面折射出后，形成近光光形的III区光形部分。
如图42所示，作为本发明的一个具体实施结构，近光III区形成结构100包括沿着次级光学元件3的上下方向延伸的多个纵向条状凸起101。
更具体地，各纵向条状凸起100的横截面外沿为中心区域高于两侧区域的外凸曲线。
进一步具体地，各纵向条状凸起101的宽度相等。
进一步地，各纵向条状凸起101的横截面外沿的曲线的中心区域高于两侧区域，且各纵向条状凸起100的宽度均相等，纵向条状凸起101便于将光线向左右方向发散。
如图43所示，作为本发明的具体实施结构的一个可选具体实施结构，近光III区形成结构100包括沿着次级光学元件3的左右方向延伸的多个横向条状凸起102。
更具体地，各横向条状凸起102的纵向截面外沿为中心区域高于两侧区域的外凸曲线。
进一步具体地，各横向条状凸起102的宽度相等。
进一步地，各横向条状凸起102的纵向截面外沿的曲线的中心区域高于两侧区域，且横向条状凸起102的宽度均相等，横向条状凸起102便于将光线向上下方向发散。
如图44所示，作为本发明的具体实施结构的另一个可选具体实施结构，近光III区形成结构100包括由外凸曲面连接成的多个块状凸起103。
作为可选具体实施结构的具体结构形式，各块状凸起103的中心区域高于四周区域，块状凸起103便于将光线向四周发散。
本发明的上述三种具体实施例中近光III区形成结构100的凸起分别是纵向条状凸起101、横向条状凸起102和块状凸起103，纵向条状凸起101能够使经过该纵向条状凸起101的光线向左右方向发散，横向条状凸起102能够使经过该横向条状凸起102的光线向上下方向发散，块状凸起103能够使经过该块状凸起103的光线向四周发散。但是本发明的近光III区形成结构100的凸起不仅限于这三种形式，还可以采用其他形状，具体形状需根据光形需要变换。
作为本发明的另一个具体实施结构，如图45至图48，近光III区形成结构100包括从入光面的左侧边缘至右侧边缘依次排列的多个纵向条状凸起101，各纵向条状凸起101相连形成条状结构，各纵向条状凸起101的入光面的纵向截线由上至下向出光方向倾斜。
可选地，如图49所示，近光III区形成结构100包括设置在入光面上的由多个纵向条状凸起101相连而成的一段凸起结构，该凸起结构的横向截面的宽度由中间向两侧逐渐减小，各纵向条状凸起101的入光面的纵向截线由上至下向出光方向倾斜。
在图41至图44所示的近光III区形成结构100是布满次级光学元件3的入光面下部区域12的凸起结构；从图45和图48中可以看出，近光III区形成结构100还可以是从入光面的左侧边缘至右侧边缘依次排列的多个纵向条状凸起101，这些纵向条状凸起101相连形成条状结构，为了满足近光III区光形的配光要求，如图48所示，该纵向条状凸起13a的入光面的纵向截面线由上至下向出光方向倾斜；而从图49和图52中可以看出，近光III区形成结构100还可以是设置在入光面上的由多个纵向条状凸起101相连而成的一段凸起结构，该段凸起结构的位置与形式可根据实际近光III区光形的形成需求来设计，例如，图49所示的该段凸起结构位于入光面上部的中间位置，其多个纵向条状凸起101的长度由中间向两侧逐渐减小，同样，如图50所示，该纵向条状凸起101的入光面的纵向截面线由上至下向出光方向倾斜，以满足近光III区光形的配光要求。当然，上述图45、图46和图49中的凸起还可以采用横向条状凸起13b或者块状凸起13c，或者其他结构形式。
如图45所示，近光III区形成结构100形成于入光面的下部，其中入光面为上下方向的平面；如图46所示，近光III区形成结构100形成于入光面的上部，该入光面亦为上下方向的平面，近光III区形成结构100在入光面上的位置变换并不会影响近光III区光形的形成，因此，根据实际需要，近光III区形成结构100可以设置在入光面的任意位置，只要采用符合近光III区配光要求的各种结构形式的近光III区形成结构100，能够使得光线 经该近光III区形成结构100射入次级光学元件3，再经过次级光学元件3的出光面折射出后，形成近光光形的III区光形部分即可。
作为本发明的另一个具体结构形式，如图50和图51所示，次级光学元件3的出光面为外凸曲面。
作为本发明的另一个具体实施方式，如图50和图51所示，次级光学元件3的入光面为平面或外凸曲面。
如果次级光学元件3出光面和入光面均为外凸曲面，则本发明的次级光学元件3为双凸透镜；如果出光面为外凸曲面，入光面为平面，则本发明的次级光学元件3为平凸透镜。在这里需要说明的是，本发明的次级光学元件3是平凸透镜还是双凸透镜，和具体的近光III区形成结构100并没有必然的对应关系，即平凸透镜和双凸透镜都可以和任一近光III区形成结构100结合使用。
本发明还提供一种车灯，该车灯内形成有光线传播路径，包括车灯照明模组、散热器6和透镜安装支架7，车灯照明模组为上述技术方案中任一项所述的车灯照明模组，其中次级光学元件3为透镜，且该次级光学元件3通过透镜安装支架7与散热器6连接，车灯照明模组安装于所述散热器6上，并且该车灯照明模组位于散热器6与透镜安装支架7围成的空腔内。
如图25和图26所示，光源可以为LED芯片，LED光源作为新能源，已逐渐取代传统光源，LED光源不仅节能环保，而且使用寿命长，亮度高，且性能稳定，发光纯度高。LED芯片安装于电路板上，近光初级光学元件1和远光初级光学元件2上可以设置定位孔、螺纹孔、定位销等连接结构，相应地，电路板与散热器6上也可以设置定位销、螺纹孔、定位孔，通过定位销、螺栓等将近光初级光学元件1和远光初级光学元件2、电路板、散热器6依次定位连接；
近光初级光学元件1和远光初级光学元件2一般为透明光学元件，如采用玻璃、硅胶或塑料等透明材质制备而成，近光初级光学元件1和远光初级光学元件2等初级光学元件能够将光源射出的光线进行初级配光(比如聚焦、准直等)，因此，初级光学元件对车灯照明效果的好坏起到了很大的作用，初级光学元件的定位和安装可靠性对车灯光形的精度和车灯照明效果影响很大；同时，设置在初级光学元件上的任何一个部件都会对光线的初级配光产生影响，过多的安装结构和定位结构会对初级光学元件的配光效果产生或多或少的影响。因此，可以通过本发明的车灯照明模组的上述技术方案中有关的限位结构将近光初级光学元件1和远光初级光学元件2与分别通过电路板、散热器6依次定位连接，得到更好的照明效果。
需要说明的是，本发明的光源可以采用LED光源，并不说明只限定为LED光源，使用激光光源或其他类似光源，均属于本发明的保护范围。光源为多颗且分散设置，这样就使得热源得以分散，提高了散热性能。
图54是未设置近光III区形成结构100的光形图，图55是设置有近光III区形成结构100的光形图。在图55所示的光形图中，光源发出的光线经近光初级光学元件1汇聚准直后射入设有本发明的近光Ⅲ区形成结构100的次级光学元件3，再由次级光学元件3的出光面折射出后，形成近光III区光形。本发明的所述光形为光线由车灯照明模组投射至配光屏幕上的光形该配光屏幕为设置在车辆前方25m处的竖直屏幕。图55中方框中所框选出的光形部分即为位于截止线上方的近光III区光形。本发明的近光III区形成结构100设于次级光学元件3的入光面上，结构更加紧凑，不易与其他零件发生干涉，且不增加制造成本。
本发明还提供一种车辆，该车辆包括上述技术方案中任一项所述的车灯。
由以上描述可以看出，本发明巧妙地在次级光学元件3上设置近光III区形成结构100，在近光初级光学元件1前端的下边界与远光初级光学元件2的前端上边界相衔接的情况下，使光线能够被顺利地投射到近光III区光形区域以形成近光III区光形，近光III区形成结构100不易与其他零件干涉，光学性能更加稳定；近光初级光学元件1前端的下边界与远光初级光学元件2的前端上边界相衔接使得两者之间形成空气层，使得光线在光通道内更好地进行全反射；采用近光初级光学元件1与远光初级光学元件2的结构设计，无需遮光板、电磁阀等零部件，占用空间体积较小，便于车灯照明模组及车灯的小型化，结构相对简化，便于车辆的结构设计；而且，近光初级光学元件1与远光初级光学元件2均可以由准直单元21组成，以形成多通道的聚光元件，便于光形的精确控制，提升光照效果，光源发出的光线在一定程度上不会混合，可以形成各自的独立光形，使得一颗光源关闭时，可以形成清晰的光形遮蔽区域，以实现近光随动转向功能或防远光炫目功能；近光III区形成结构100具有多种结构形式，结构简单，加工方便，可以满足各种不同的设计需求。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
