技术领域
本发明涉及车辆照明装置，具体地涉及一种前照灯模组，另外，还涉及一种前照灯及车辆。
背景技术
近年来，车灯及装配于车灯中的前照灯模组得到了快速发展，从早先的卤素灯到后来的疝气灯，再到现在的LED、激光光源，使得车灯变得更加智能化，且造型上也更加差异化。在各种车灯光源中，LED光源因其优异的性能和低成本优势，正逐渐得到汽车厂家的重视，而伴随着LED光源的发展，其配光结构也逐渐在发展。
现有技术中的汽车车灯中常用的LED光源的投射式照明系统，一般都包括光源、反射元件、遮光板以及光学透镜。反射元件为椭球形反射镜，光源的发光中心设置在椭球形反射镜的近焦点处，光源发出的光线经过椭球形反射镜反射后汇聚于椭球形反射镜的远焦点附近，遮光板设置于椭球形反射镜的远焦点处，其形状与法律规定的明暗截止线形状一致，最后通过光学透镜形成带有明暗截止线的类平行光照明光形。但由于LED光源的发光角度大，反射元件的尺寸需要相对光源出光角度有较大的覆盖范围，才能保证一定的系统光效，但这和未来汽车造型越发紧凑的趋势存在突显的矛盾。因此需要一种紧凑、灵巧、高效的光学系统来满足市场强烈的需求。
鉴于现有技术的上述缺陷，需要设计一种新型的前照灯模组。

本发明要第二方面要解决的技术问题是提供一种前照灯，该前照灯更加小型化且光线利用率较高。
本发明要第三方面要解决的技术问题是提供一种车辆，该车辆的前照灯更加小型化且光线利用率较高。
为了实现上述目的，本发明第一方面提供一种前照灯模组，包括沿光线出射方向依次设置的集光部、反射部、出光部、第一光通道和第二光通道，所述第一光通道连接所述集光部和所述反射部，所述第二光通道连接所述反射部和所述出光部，所述第二光通道的下表面与所述出光部的连接处设有用于形成近光明暗截止线的近光截止线结构；或者，所述第二光通道的上表面与所述出光部的连接处设有用于形成远光明暗截止线的远光截止线结构，所述反射部的上边沿位于所述出光部的上边沿下方，所述反射部的下边沿位于所述出光部的下边沿上方，所述集光部汇聚的光线能够经所述反射部反射后射向所述出光部。

具体地，所述集光部远离所述反射部的一端开设有内凹腔体，所述内凹腔体包括前入光面和侧入光面，所述前入光面为向远离所述反射部的一侧凸出的曲面，所述侧入光面为由远离所述反射部的一端向靠近所述反射部的一端周长逐渐减小的曲面，所述集光部后部的外部轮廓面为由远离所述反射部的一端向靠近所述反射部的一端周长逐渐增大的曲面。
优选地，所述第一光通道与两个以上所述集光部相连接，所述第三光通道与两个以上所述聚光部连接，其中，位于中间位置的所述集光部相较于位于两侧位置的所述集光部的尺寸更大，以能够汇聚更多的光线，位于中间位置的所述聚光部相较于位于两侧位置的所述聚光部的尺寸更大，以能够汇聚更多的光线。

本发明第三方面提供一种车辆，包括第二方面技术方案中所述的前照灯。
本发明的基础技术方案中，该前照灯模组包括沿光线出射方向依次设置集光部、 反射部和出光部，其中，反射部的上边沿位于出光部的上边沿下方，反射部的下边沿位于出光部的下边沿上方，集光部汇聚的光线能够经反射部反射后射向出光面。由于出光部的上边沿位于反射部的上边沿上方，出光部的下边沿位于反射部的下边沿下方，出光部能够接收到反射部反射的绝大部分光线，使得该前照灯模组的光线利用率较高；并且，光源发出的光线经集光部汇聚后形成角度较小的光束后射向反射部，使得该光源发出的光线能够完全或绝大部分的入射到反射部，实现较高的光效的同时还能够减小反射部的尺寸，使得该前照灯模组趋于小型化。

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。
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“连接”、“设置”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，沿出光部3的光轴31方向，“前”是指出光部3所在端，“后”是指光源6所在端；“光轴31”是指过出光部3的焦点，沿前后方向延伸的轴线；“上”是前照灯模组正常安装时，光轴31方向的上方；“下”是指前照灯模组正常安装时，光轴31方向的下方，术语为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，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。
本发明的基础技术方案的前照灯模组，包括沿光线出射方向依次设置集光部1、反 射部2和出光部3，其中，反射部2的上边沿位于出光部3的上边沿下方，反射部2的下边沿位于出光部3的下边沿上方，光源6发出的光线经集光部1汇聚后射向反射部2，反射部2再将光线反射至出光部3。
需要说明的是，如图6所示，上述光线出射方向为前照灯模组内的光路走向。
上述前照灯模组可以采用分体式结构，参考图14至图17，反射部2为一块倾斜设置的反射板，出光部3为透镜。上述前照灯模组也可以采用一体式结构，参考图1至图13，该前照灯模组还包括第一光通道41和第二光通道42，第一光通道41连接集光部1和反射部2，第二光通道42连接反射部2和出光部3，其中，第二光通道42的上边沿位于出光部3的上边沿的下方，第二光通道42的下边沿位于出光部3的下边沿的上方，集光部1汇聚的光线能够经反射部2反射后射向出光部3，具体地，集光部1汇聚的光线经第一光通道41传输至反射部2，再经反射部2反射后由第二光通道42传输至出光部3。
在该前照灯模组中，无论采用分体式结构还是一体式结构，由于出光部3的上边沿位于反射部2或第二光通道42的上边沿上方，出光部3的下边沿位于反射部2或第二光通道42的下边沿下方，在此种结构下，出光部3能够接收到反射部2反射的绝大部分光线，该前照灯模组的光利用率较高；并且，光源6发出的光线经集光部1汇聚后形成角度较小的光束后射向反射部2，使得该光源6发出的光线能够完全或绝大部分的入射到反射部2，实现较高的光效的同时还能够减小反射部2的尺寸，使得该前照灯模组趋于小型化；另外，集光部1分别对应光源6，光源6分散式排布，使得该前照灯模组散热效果好。
当该前照灯模组采用一体式结构时，该前照灯模组可以采用玻璃、PC、PMMA或硅胶等材质一体成形，采用一体成形的生产工艺降低了前照灯模组的结构复杂性，简化了生产的工序流程，节约了生产成本，避免了装配误差从而保障出射光形稳定。
在图1至图9所示出的实施例中，上述前照灯模组为近光照明模组，其第二光通道42的下表面与出光部3的连接处还可以设有用于形成近光明暗截止线的近光截止线结构421。近光截止线结构421的形状与近光明暗截止线的形状相匹配，反射部2反射的光线经第二光通道42的近光截止线结构421截取后，射向出光部3，由出光部3投射形成如图22所示的具有近光明暗截止线71的近光光形。优选地，该近光截止线结构421位于出光部3的光轴31的上侧2mm至下侧2mm的区域内，进一步优选地，该近光截止线结构421经过出光部3的焦点以能够形成更加清晰的近光明暗截止线71。
在图11至图13所示出的实施例中，上述前照灯模组为远光照明模组，其第二光通道42的上表面与出光部3的连接处还可以设有用于形成远光明暗截止线的远光截止线结构422。远光截止线结构422的形状与远光明暗截止线的形状相匹配，反射部2反射的光线经第二光通道42的远光截止线结构422截取后，射向出光部3，由出光部3投射形成如图23所示的具有远光明暗截止线72的远光光形。优选地，该远光截止线结构422位于出光部3的光轴31的上侧2mm至下侧2mm的区域内，进一步优选地，该远光截止线结构422经过出光部3的焦点以能够形成更加清晰的远光明暗截止线72。
可选择的，在图1至图6所示出的实施例中，第一光通道41和集光部1位于出光部3的光轴31的下侧；在图7至图9所示出的实施例中，第一光通道41和集光部1位于出光部3的光轴31的上侧。无论第一光通道41和集光部1位于光轴31的上侧还是下侧，只要近光截止线结构421在出光部的光轴附近，均能够形成清晰的近光光形，实际使用中可以根据车灯造型需要选择该前照灯模组的具体结构。第一光通道41和集光部1的位置变换同样适用于图11至图13所示的远光照明模组的实施例。
在图20和图21所示的实施例中，上述前照灯模组还可以为远近光一体照明模组，其还包括第三光通道43和至少一个与第三光通道43连接的聚光部8，其中，聚光部8、第三光通道43和出光部3依次连接。图20和图21所示为在图7至图9所示的近光照明模组的基础上，在第二光通道42的下方增加第三光通道43，形成远近光一体照明模组，与第三光通道43连接的聚光部8汇聚光光线能够经第三光通道43传输至出光部3，经出光部3投射后形成远光光形，优选地，第三光通道43的上表面与出光部3的连接处可设置用于形成远光明暗截止线72的远光截止线结构422。应用上述远近光一体照明模组时，打开近光光源，光线经集光部1汇聚后射向反射部2，反射部2反射的光线经第二光通道42的近光截止线结构421截取后，射向出光部3，由出光部3投射形成近光光形；当需要远光照明时，再打开远光光源，远光光源发出的光线经聚光部8汇聚后直接由第三光通道43射向出光部3，由出光部3投射出去形成远光光形，并与近光光形共同形成完整的前照灯光形。
当然，也可以在图1至图6所示的近光照明模组的基础上，增加图11、图12或图13所示的远光照明模组形成远近光一体照明模组；或者，在图11、图12和图13所示的远光照明模组的基础上，在第二光通道42的上方增加第三光通道43，其中第三光通道43的下表面与出光部3的交汇处设有近光截止线结构，形成远近光一体照明模组，与第三光通道43连接的聚光部8汇聚的光线能够经第三光通道43的近光截止线结构截 取后，传输至出光部3，经出光部3投射后形成近光光形。可以根据车灯造型需要灵活布置该前照灯模组，使得车灯造型更加新颖、多变，满足用户对于个性化、科技感的车灯造型的需要。
作为一种具体地结构，参考图4所示，与第一光通道41连接的集光部1和与第三光通道43连接的聚光部8可以采取相同的结构形式，并且带来相同或相近的有益效果。下面具体描述与第一光通道41连接的集光部1的结构，该集光部1远离所述反射部2的一端开设有内凹腔体11，内凹腔体11包括前入光面111和侧入光面112，前入光面111为向远离反射部2的一侧凸出的曲面，侧入光面112为由远离反射部2的一端向靠近反射部2的一端周长逐渐减小的曲面，集光部1后部的外部轮廓面12为由远离反射部2的一端向靠近所述反射部2的一端周长逐渐增大的曲面。内凹腔体11的开口朝向光源6以接收来光源6发出的光线，其中，所述光源6优选地为LED光源，与第一光通道41连接的集光部1通过前入光面111可对光源6所发出的部分光线进行汇聚，侧入光面112则可对光源6所发出的其它光线进行折射，且折射后再通过外部轮廓面12进行反射，由此可基本实现对光源6发出光束的全利用，可达到提高光源光束利用率的目的。并且光源6发出的光线经集光部1汇聚后，能够形成角度较小的光束，使得该光源6发出的光线能够完全或绝大部分的入射到反射部2，实现较高的光效的同时还能够减小反射部2的尺寸，使得该前照灯模组趋于小型化。
更具体的，第一光通道41可以与两个以上集光部1相连接，同理，第三光通道43可以与两个以上聚光部8相连接。其中，位于前照灯模组的中间位置的第一光通道41的集光部1相较于位于两侧位置的集光部1的尺寸更大，由于该前照灯模组投射形成的光形的中心区域照度要求高，所以中间位置的集光部1尺寸更大，以能够汇聚更多的光线，从而提高光形中心区域的照度。更加形象的，参考图2所示，位于中间位置的集光部1的尺寸更大，相应的，该集光部1的内凹腔体11能够对应更多颗的LED，该LED光源与该集光部1对应形成中心区域光形。同理可得，第三光通道43对应的聚光部8可以与第一光通道41对应的集光部1的布置方式相同，并且带来相同或相近的有益效果。
前照灯模组为分体式结构时，参考图14至图17所示，出光部3、集光部1和反射部2可以分别装配于前照灯模组的安装支架上。采用分体式结构的前照灯模组便于调节各个光学元件之间的相对位置，能够适应多样化的车灯造型。
在图14至图17所示出的实施例中，光源6发出的光线经集光部1汇聚后射向反 射部2，反射部2将光线射向出光部3，再由出光部3投射出去以形成照明光形。
在图18和图19所示出的实施例中，该前照灯模组还可以在图14至图17所示出的实施例的基础上增加遮光板5，该遮光板5上靠近出光部3的一端形成有截止部51，集光部1汇聚的光线能够射向反射部2，经反射部2射向遮光板5，并由遮光板5的截止部51截取后射向出光部3以形成近光光形。
进一步优选地，参考图10所示，出光部1可以采用菲涅尔透镜结构，可以使得该前照灯模组重量更轻、成本更低。可以理解的是，该种结构的透镜可以适用于本发明的任一种实施方式中的前照灯模组。
需要说明的是，当上述前照灯模组采用一体式结构时，其仅需这一个一体成形的光学元件就可以实现所需光形，不需要设置其他光学元件，结构简单。当然，为了前照灯造型等需求，可以在该一体光学元件和外配光镜之间设置至少一个内配光镜，该内配光镜可以是普通等壁厚塑料件，只为呈现所需造型，还可以是背面具有配光功能的配光塑料件。
本发明还提供了一种前照灯，其包括上述各实施例中的前照灯模组，将上述实施例中的前照灯模组安装于前照灯上时，可以竖向分布、水平分布、或者倾斜排列分布，使用时可用单组、两组或者多组的配合实现前照灯照明的单一功能或多个功能，包括近光、远光、前雾灯和角灯等。
本发明还提供了一种车辆，其包括上述前照灯。
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。
