现有技术中的车灯模组具有初级光学元件和次级光学元件，需要通过初级光学元件和次级光学元件的两次配光调整得到所需光形，两次配光调整相比只设置一个光学元件的一次配光调整更加灵活，这是因为可以通过调整两个光学元件的配光参数来调整光形，可调的配光参数较多，例如，可以调整初级光学元件的入光面、出光面以及次级光学元件的入光面或者出光面。
现有技术中存在以下缺陷：
1、普遍采用具有多个聚光结构的聚光器作为初级光学元件，聚光器大致沿前后方向延伸，加上设置在聚光器前端的透镜作为次级光学元件，这会导致车灯模组的整体尺寸增大，占用空间多；此外还需要保证两个光学元件之间的相对位置准确，对装配精度的要求高；
2、当将聚光器作为近光光学元件使用时，还需在聚光器前方设置遮光 板以形成近光截止线，这会进一步导致车灯模组的结构复杂，尺寸增大；
3、功能单一，只能实现近光、远光、辅助近光和辅助远光中的一种功能。
发明内容

具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细说明。这些实施方式仅用于说明本发明，而并非对本发明的限制。
在本发明的描述中，需要说明的是，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系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。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
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”、“相连”、“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，或一体地连接。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。
此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在以下的描述中，以图4中的附图作为方向的参考基础，沿视图纸面向上为上方向，沿视图纸面向下为下方向，沿视图纸面朝右、第一出射光面12所在的一侧为前方向，沿视图纸面朝左为后方向，垂直于视图纸面朝里为左方向，垂直于视图纸面朝外为右方向。附图中的所有单点划线代表的是光轴。
如图1所示，本发明提供了一种车灯光学元件1，其包括两个光学部，每个光学部呈弯折型，包括相互连接的聚光通道13和导光通道14，两者的连接处设有反射面15。聚光通道13大致沿上下方向延伸，一端设有多个聚光结构11，导光通道14大致沿前后方向延伸，前端设有出射光面。两个光学部上下设置，且两个导光通道14之间顶底相连，即上方导光通道14的底面与下方导光通道14的顶面相连，使得车灯光学元件1看上去大致呈┣型。这样设置的车灯光学元件1在前后方向上的尺寸得以缩短，所需安装空间也相应减小。
以下为本发明的几个应用实施例：
实施例一
如图1-4所示，每个光学部的出射光面为向车灯光学元件1的内侧凹陷 的弧形面，两个出射光面相连接，形成与透镜2的物体焦面相配合的第一出射光面12。两个出射光面还可以优选地设置为光滑出射光面121，消除两者之间的分界线，从而提高出射光形在两个光学部连接处的连续性和均匀性。工作时，车灯光学元件1作为初级光学元件，透镜2作为次级光学元件，线路板3上的光源31发出入射光线，聚光结构11能够接收入射光线并聚光，聚光后的入射光线进入聚光通道13，经反射面15反射后进入导光通道14，由第一出射光面12射出，光线再依次经过透镜入射光面22和透镜出射光面21射出，完成二次配光后投射在车辆的前方。车灯光学元件1和透镜2的组合可以用于实现近光、远光、辅助近光、辅助远光或远近光一体中的一种功能。
实施例二
该实施例的车灯光学元件是在实施例一的基础上作了进一步改进，如图5和图6所示，两个光学部的出射光面均为向外侧凸出的弧形面，两个出射光面相连接，形成光滑连续的第二出射光面16，该第二出射光面16可以为沿车灯光光学元件1的左右方向延伸的弧形面，或者，为凸透镜面，这里的凸透镜面具体指的是由凸透镜的出光面截线经回转后得到的回转面。工作时，聚光结构11接收入射光线并聚光，聚光后的入射光线进入聚光通道13，经反射面15反射后进入导光通道14，由第二出射光面16射出，投射在车辆的前方。实施例二将现有技术中的初级光学元件和次级光学元件作成一体，安装时不需要保证两者的相对位置精度，能够更好地确保光形的稳定性。
实施例三
为了在一体设置的车灯光学元件的基础上更好地调整出射光形，该实施例的车灯光学元件在实施例二的基础上作了进一步改进，如图7和图8所示，车灯光学元件1上开有隔槽4，隔槽4贯通两个导光通道14，且包 括相对设置的出光面41和入光面42，优选地，出光面41和入光面42的延伸方向与第二出射光面16的延伸方向相同。通过隔槽4将一体的车灯光学元件1分成前后两个部分，位于前侧的部分对应现有的次级光学元件，位于后侧的部分则对应现有的初级光学元件，使得车灯光学元件1在具有一体件的优势的同时还能实现二次配光。工作时，入射光线由聚光结构11进入聚光通道13，经反射面15反射后进入导光通道14，然后依次经出光面41、入光面42和第二出射光面16射出并投射在车辆的前方。其中，隔槽4可以上下贯通和/或左右贯通，隔槽4的出光面41和入光面42可以有多种形式，如平面、凹面或凸面等。
实施例四
为了能够在移除遮光板的同时形成近光截止线，该实施例的车灯光学元件在实施例二的基础上作了进一步改进，如图9所示，位于下方的导光通道14的底面开有纵截面呈V型的尖槽5，尖槽5向上凹陷，包括远离第二出射光面16的尖槽反射面51和靠近第二出射光面16的尖槽侧面52，优选地，尖槽反射面51和尖槽侧面52的延伸方向均与第二出射光面16的延伸方向相同。尖槽反射面51和尖槽侧面52的连接处53(即尖槽5的顶部)的形状与近光截止线形状相适应，用于形成近光截止线，其形状根据近光截止线的不同形状而不同。上方光源(未示出)射出光线从上方聚光结构11进入后经反射面15反射，经连接处53截止，再由第二出射光面16射出，形成近光截止线，而由下方光源(未示出)射出的光线从下方聚光结构11进入，大部分入射光线经反射面15反射后会射至尖槽反射面51，发生全反射。因此，在工作时，下方光源的光线利用率较低，只有较少部分的光线可以经反射面15反射后直接从第二出射光面16射出。
实施例五
如图10所示，为了提高实施例四中下方光源(未示出)的光线利用率， 实施例五在实施例四的基础上作出了进一步改进，降低了尖槽5的高度，即降低了尖槽反射面51的高度，使得更多由下方聚光结构11进入的入射光线经反射面15反射后，可以避开尖槽反射面51的全反射，直接由第二出射光面16射出。优选地，为了便于在位于下方的导光通道14的底面上加工尖槽5，可以将连接处53设置为尖角以外的形状，如采用在前后方向上延伸较短距离的平面或半径较小的圆弧面。
实施例六
为了实现远近光一体模式，该实施例的车灯光学元件在实施例二的基础上作了进一步改进，如图11和图12所示，位于下方的导光通道14的底面开有向上凹陷的凹槽6，凹槽6包括相对设置的前侧面62和后侧面61，两者之间通过连接面63相连接，前侧面62和后侧面61的延伸方向与第二出射光面16的延伸方向相同，且前侧面62相对后侧面61更靠近第二出射光面16。连接面63与前侧面62的连接处为前边缘64，前边缘64的形状与近光截止线形状相适应，用于形成近光截止线，其形状根据近光截止线的不同形状而不同。
如图11所示，位于上方的光学部具有第一反射面151，该第一反射面151将上方光源发出的大部分入射光线反射至凹槽6的前边缘64。具体地，上方光源发出的入射光线均从位于上方的聚光结构11进入，路径分三部分，第一部分入射光线A被第一反射面151反射至前边缘64，但不在前边缘64上进行任何反射，直接从第二出射光面16折射出。第二部分入射光线B直接被第一反射面151反射至第二出射光面16的顶部，并保持向光学轴线靠近的下倾方向离开第二出射光面16。第三部分入射光线C被第一反射面151反射至连接面63，然后被连接面63反射至第二出射光面16的顶部，并保持向光学轴线靠近的下倾方向离开第二出射光面16，其中，大部分射至连接面63上的光线均发生全反射。前述三部分光线A、B、C可用于产生近光光形。
如图12所示，位于下方的光学部具有第二反射面152，该第二反射面152将下方光源发出的大部分入射光线反射至凹槽6的后侧面61，光线穿过凹槽6，经前侧面62折射至第二出射光面16。具体地，下方光源发出的入射光线均从位于下方的聚光结构11进入，路径分两部分，一部分入射光线D被第二反射面152反射至后侧面61，再折射至前边缘64，然后直接由第二出射光面16的顶部射出；另一部分入射光线E被第二反射面152反射至后侧面61，光线折射至前侧面62，再折射至第二出射光面16射出。前述两部分光线D和E可用于产生远光光形，并与上述近光光形衔接。
另外，上述聚光结构11有多种表现形式，其一，可以是如图8所示的具有凹腔的聚光杯结构，其外部轮廓为由光源所在处向反射面15所在处逐渐增大的曲面状结构，其凹腔开口朝向远离聚光通道13的一侧开设，凹腔底部设有向远离聚光通道13的一侧凸出的凸起；其二，聚光结构11的内部不开设凹腔，仅为外部轮廓为由光源所在处向反射面15所在处逐渐增大的曲面状结构的实心体，其入光面的形状可以为平面，也可以为曲面；其三，聚光结构11还可以是设置在聚光通道13的端部且向远离聚光通道13的一侧(即外侧)凸出的凸起。该聚光结构11可以设置一排或多排，其有助于将光源发出的光线很好地收集、准直，提高光线利用率。
综上所述，本发明的有益之处在于：
1、包括两个呈弯折型的光学部，缩短了车灯光学元件在前后方向上的尺寸，减少安装所需空间；
2、将现有技术的初级光学元件和次级光学元件作成一体件，可以有效减少零部件的数量，安装时不再需要保证两者的相对位置精度，能够更好地确保车灯光形的稳定性，同时也减小了车灯模组的尺寸；
3、通过开设隔槽，可以在一体式的车灯光学元件中实现二次配光，提高配光的灵活性；通过开设尖槽替代现有的遮光板，既实现了近光截止线， 也简化了车灯模组的结构，减小了整体尺寸；
4、通过开设凹槽，可以在一体式的车灯光学元件中同时实现远光和近光功能，使得车灯光学元件的功能多样化。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，如在实施例一的车灯光学元件的基础上开设隔槽、尖槽或凹槽，同时配以透镜作为次级光学元件，实现相应功能。本领域技术人员可以根据需要灵活调整，这些改进和替换也应视为本发明的保护范围。
