需要说明的是，在不冲突的情况下，本公开的实施例中的特征可以相互结合。
如图1-8所示，本公开实施例提供的光学模组，包括：聚光组件100和多个远光光源210，多个远光光源210沿同一方向间隔设置，聚光组件100包括聚光器110，聚光器110包括多个导光件111，各导光件111的入光端112与各远光光源210一一对应设置，各导光件111的出光端汇聚在一起并形成弧形的出光部113，相邻的导光件111之间的夹角均为锐角。
本公开实施例提供的光学模组应用于车灯中，在开启远光灯后，远光光源210发射出来的光线经由导光件111的入光端112进入导光件111，并从导光件111的出光部113射出。由于各远光光源210对应的导光件111的出光端汇聚在一起，因此聚光器110对于各远光光源210发出的光线起到汇聚作用，且使得相邻的远光光源210发出的光线在导光件111的出光部113有一定的融合，从而使得发出的光线的光型衔接更为均匀。
由于远光光源210的数量为多个，且沿同一方向间隔设置，不同的远光光源210发出的光线的照射区域不同，因此可通过控制各远光光源210的亮灭来控制车灯的照射区域，以避开对向行驶的车辆所在区域，从而避免发生对向车辆的驾驶员目眩的现象。值得说明的是，远光光源210可以使用LED光源(LED light source)。
结合图6，导光件111的出光端汇聚在一起并形成弧形的出光部113，该弧形在靠近导光件111的入光端112的方向上凹陷，以实现发光后的聚光效果。同时，可选的，左、右两侧远光光源210与对应的出光部113的距离大于中间的远光光源210与对应的出光部113的距离；可以理解的，远光光源210距离中间的位置越远，这个距离越大，用以减小左右两侧远光光源210相对透镜的 呈像差，这里所讲的“中间”是指最中间一颗远光光源210或中间两颗远光光源210的中心。
同时，相邻的导光件111之间的夹角均为锐角，可以理解为，图6中，导光件111呈条形，其中一个导光件111的长度方向与相邻的另一个导光件111的长度方向之间的夹角为锐角；或，也可以理解为，其中一个导光件111中光线的传播方向与相邻的另一个导光件111中光线的传播方向之间的夹角为锐角。锐角的范围为0°-90°，可选的，例如：5°-45°。
结合图6和图7，多个导光件111并排设置，相邻的两个导光件111之间设置有楔形间隙，该楔形间隙的小端相对远离远光光源210，该楔形间隙的大端相对靠近远光光源210，远光光源210发出的光线在导光件111内传播时，各个导光件111内的光线各自独立在对应的导光件111内传播，光线传播至上述楔形间隙的小端后，原在各自导光件111内传播的光线进行融合，并射出出光部113。
举例来说，当远光光源210的数量为三个时，三个远光光源210分别配置成照射左侧区域、中部区域和右侧区域，当对向的车从左侧驶来时，关闭照射左侧区域的远光光源210，仅开启照射右侧区域和中部区域的远光光源210，从而保证本车驾驶员可以获得较为广阔的视野且不会使得对向的驾驶员出现炫目的现象。
如图8所示，光学模组还包括远光线路板200，远光光源210安装于远光线路板200上。在图8中，远光光源210的数量为十个，且远光光源210沿线路板的长度方向间隔排列。如此设置，可以将车灯的照射区域划分为十个区域， 并分别控制，从而有更多种控制方式，有益于实现在保证不照射对向车辆驾驶员的基础上，进一步扩大照射区域，且增加照射亮度的多种选择。
在本实施例中，远光光源210的数量可选为3-26个，在实际应用过程中，可根据需求进行选择。当远光光源210的数量相对较少时，较为省电且易于控制，当远光光源210的数量较多时，对于照射区域的划分更为细致，可实现更多种控制方式，且亮度较大。
在本实施例中，导光件111的数量与远光光源210的数量相等，且一一对应设置，如图6和图7所示，导光件111的宽度由导光件111的入光端112一侧向导光件111的出光端一侧逐渐增大。
同时，可以理解的，导光件111的数量与远光光源210的数量也可以不相等，例如，当用户需求是12个照明区域的模组，则可以提供模组A，具有12个导光件111和12个远光光源210，实现12个照明区域；当用户需求是10个照明区域，为了降低开发和制造成本，还是沿用上述的12个导光件111，将远光光源210的数量更改为10个(比如去掉最左和最右各1个)，形成模组B，此时导光件111的数量大于远光光源210的情况。
同时，结合图6和图7，这里所指的“宽度”可以理解为，以图6和图7中的相对位置作介绍，“宽度”指的是导光件111在左右方向上的距离，也可以理解为沿各个导光件111排布方向上的距离。
结合图7，导光件111的入光端112的端面为圆弧状，入光端112的端面设置有聚光槽114，聚光槽114为类似圆柱凹槽，聚光槽114的侧壁和底部带 有一定曲率。聚光槽114的中心点与远光光源210的中心点对应，从而增加对于远光光源210发出的光线的利用率。聚光槽114的设置使得远光光源210发出的光更多地被收集到导光件111中，有效提高光效。
一般的，聚光槽114的中心点与远光光源210的发光面的中心点之间的距离≤2mm，可选的，两个中心点重合设置。
可选的，各导光件111之间连接有加强筋115。具体实施时，加强筋115连接于导光件111靠近入光端112的一侧，加强筋115配置成提高结构强度及各导光件111之间的相对精度，保证各导光件111之间相对距离不变。在本实施例中，导光件111与加强筋115为一体结构。
在本实施例中，聚光器110采用透光材料，可选为透明硅胶材料，优势为透明硅胶耐温高，长期光照不易黄化，且材质较软，可与光源较近距离安装，光效高。选用PC(Polycarbonate，聚碳酸酯)、PMMA(polymethyl methacrylate，聚甲基丙烯酸甲酯)、玻璃或其他透明树脂材料，亦可实现功能。
可选的，光学模组还包括散热器800，为便于为远光线路板200散热，远光线路板200安装于散热器800上。为便于将聚光组件100固定，聚光组件100还包括安装支架118，聚光器110通过安装支架118与散热器800连接。
为保证安装支架的连接强度，安装支架采用金属材料制作，且在其表面做亚光黑色处理，以避免不必要的反光。
如图4和图5所示，可选的，安装支架118包括均与聚光器110连接的第一连接件120和第二连接件130，第一连接件120上设置有多个限位槽121， 聚光器110的导光件111的入光端112伸出限位槽121，第一连接件120和第二连接件130分别位于聚光器110的相对的两侧。
为便于将聚光器110与安装支架118连接，结合图6，聚光器110的两侧均设置有安装角116，安装角116上设置有安装孔，在第一连接件120和第二连接件130上与安装孔对应的位置分别设置有通孔。安装支架118与聚光器110之间可通过紧固件连接，例如螺栓或者定位销等连接，在图5中采用定位销140实现安装支架118和聚光器110的连接。
以图5中的相对位置介绍，第一连接件120位于聚光器110的下方，第二连接件130位于聚光器110的上方，第二连接件130和第一连接件120从上下方向夹持聚光器110，定位销140由上至下分别穿过第二连接件130上的通孔，聚光器110上的安装孔以及第一连接件120上通孔，从而连接安装支架118和聚光器110。
可选的，如图4所示，为了在安装定位销140之前将第一连接件120与第二连接件130进行初定位，在第一连接件120的上表面设置有限位柱122，在第二连接件130上设置有与限位柱122配合限位孔131。
在安装过程中，将限位柱122***限位孔131中，从而进行初定位，在安装完成后，限位柱122与限位孔131的配合也对第一连接件120和第二连接件130起到限位作用。
为了便于将聚光器110与第一连接件120进行初定位，将聚光器110的入光端112放入对应的限位槽121中，限位槽121一方面对聚光器110起到限位 作用，另一方面可将各导光件111的入光端112隔开，避免相互窜光。如图5所示，限位槽121为U型槽，且开口向上，聚光器110的入光端112由上至下放入U型槽中。
可选的，在聚光器110的出光部113的底部设置有翻边117，在第一连接件120的顶部设置有容纳该翻边117的容纳槽123。在将聚光器110放置于第一连接件120上时，使得翻边117伸入容纳槽123中，从而起到初定位的作用。
在本实施例中，安装支架118与散热器800之间通过螺栓连接，为了便于在安装支架118与散热器800连接时进行初定位，在散热器800上设置有定位柱810，在安装支架118上设置有与定位柱810配合的定位槽124。
具体地，在第一连接件120的两端均设置有定位槽124，定位槽124与定位柱810之间为过盈配合，为了使得定位槽124与定位柱810之间的连接更紧密，定位槽124的侧面可由两个相对的圆弧面以及两个相对的平面围成，或者，在定位槽124中设置定位筋。两个定位槽124的结构可相同也可不同，例如，在图4中，位于左侧的定位槽124由两个相对的圆弧面以及两个相对的平面围成，位于右侧的定位槽124中设置四个定位筋，各定位筋在定位槽124中沿定位槽124的周向均匀分布。
如图8所示，在远光线路板200上设置有矩形的孔，定位柱810从矩形孔中伸出，以与定位槽124配合。当然，孔的形状不限于矩形，还可以为圆形、多边形等形状。
远光线路板200上还设置有插接件220，配置成连接电源或者控制装置， 从而对各远光光源210进行控制。
在本实施例提供的光学模组中，还可集成近光功能。如图3所示，光学模组还包括近光光源710和近光反射镜600，近光光源710发出的光线经由近光反射镜600射出，聚光器110的出光部113的上部区域位于近光反射镜600反射出的光线的光路中。如此设置，聚光器110的出光部113的上部区域可形成近光截止线(Cut-off line)。集成近光的截止作用，使得集成近光的车灯模组的结构简化，聚光器110的出光部113的上端边线可以为近光截止线形状，这样经由出光部113的上部区域射出的近光光线可以形成具有近光截止线的近光光型。
可选的，由于远光角度范围在水平方向相对狭窄，近光的宽度相对较大，因此为了形成整个近光的截止线，第二连接件130包括相互连接的压板132与延伸部133，压板132与聚光器110靠近入光端112的区域接触，延伸部133的侧面与聚光器110的出光部113的侧面对合。
延伸部133为弧形，当将延伸部133与聚光器110的出光部113对合后，延伸部133与出光部113形成宽度更宽的弧形结构，延伸部133配合聚光器110的出光部113的上边界，形成完整的近光截止线。
延伸部133的数量可以为一个或者两个，当延伸部133的数量为一个时，延伸部133与聚光器110的出光部113的其中一侧对合；如图4和图5所示，当延伸部133的数量为两个，两个延伸部133分别与聚光器110的出光部113的两侧对合。
可选的，结合图4，聚光器110的出光部113的顶面包括第一平面134和第二平面135，聚光器110水平放置时，第一平面134所处水平面高于第二平面135所处水平面，第一平面134与第二平面135之间形成有斜面136。
位于第一平面134一侧的延伸部133的顶面与第一平面134处于同一水平面，位于第二平面135一侧对合的延伸部133的顶面与第二平面135处于同一水平面。斜面136与第一平面134之间的夹角可为15°、30°、45°等角度。
可以理解的，通过第一平面134、第二平面135和斜面136的设置，可以在出光部113的上端(顶面)形成具有一定拐点斜度的截止线；当然了不区分上述三个面也可以实现，例如将出光部113的顶面设置为和出光部113交线为截止线形状的异型曲面也可以达到该目的。
如图1-3所示，可选的，一个具体的实施例中，光学模组包括透镜300、透镜支架400、调光支架500、聚光组件100、远光线路板200、近光反射镜600、近光线路板700和散热器800。其中，透镜300通过透镜支架400固定，调光支架500连接透镜300以及散热器800等结构，近光线路板700和远光线路板200均安装于散热器800上，近光线路板700安装于散热器800的上部且与近光反射镜600对应设置，远光线路板200设置于散热器800朝向透镜300的一侧。聚光组件100与散热器800连接，聚光组件100中聚光器110的入光端112朝向远光线路板200上的远光光源210，聚光器110的出光部113朝向透镜300。为了加快散热器800的散热效率，光学模组还包括风扇900，风扇900位于散热器800背离透镜300的一侧。
散热器800可为金属铝压铸件。透镜300为凸透镜，透镜300的焦面处于 聚光器110与延伸部133共同形成的近光截止线的附近。
