如图 1 _图 1 1 所示， 本公开提供一种车灯模组， 包括： 近光反射镜 2、 远 光聚光器 4、 透镜 6、设置有近光光源 1 a的近光线路板 1 以及设置有远光光源 3a 的远光线路板 3。 近光反射镜 2 作为近光的一级光学元件， 远光聚光器 4 作为远光的一级光学元件。 以图 1示出的视角为例， 近光线路板 1设置在近光 反射镜 2的下侧位置， 且近光线路板 1 上的近光光源 1 a的光学中心位于近光 反射镜 2的第一焦点 10处； 远光聚光器 4设置在近光线路板 1 的前侧位置， 且远光聚光器出光面 4d位于近光反射镜 2的第二焦点 1 1 处，远光聚光器出光 面 4d的上侧边线 401的位置与近光反射镜 2的第二焦点 1 1在前后方向上的距 离 2mm， 可选的， 远光聚光器出光面 4d的上侧边线 401 的位置与近光反射镜 2的第二焦点 1 1在前后方向上的距离为 0mm， 也即二者位置重合， 此种结构设 置能够提高光学效率； 远光聚光器出光面 4d的上侧边线 401 具有近光截止线 的形状以配置成截取近光光线从而形成近光光形； 透镜 6设置在远光聚光器 4 的前侧位置， 配置成接收由远光聚光器 4的远光聚光器出光面 4d传播出来的 光线。 近光光源 1 a发出的光线经近光反射镜 2反射后， 经远光聚光器出光面 4d上方射向透镜 6， 并经透镜 6折射后形成近光光形； 远光光源 3a发出的光 线经远光聚光器 4折射以及反射后由远光聚光器出光面 4d出射并射向透镜 6, 经透镜 6折射后形成远光光形 H i。
相对于现有技术， 本公开的车灯模组具有至少以下优势：
本公开提供的车灯模组中， 如图 1 _图 1 1 所示， 包括： 近光反射镜 2、 远 光聚光器 4、 透镜 6、设置有近光光源 1 a的近光线路板 1 以及设置有远光光源 3a 的远光线路板 3。 近光反射镜 2 作为近光的一级光学元件， 远光聚光器 4 作为远光的一级光学元件； 以图 1 或者图 2 示出的视角为例， 近光线路板 1 设置在近光反射镜 2的下侧位置， 且近光光源 1 a的光学中心位于近光反射镜 2的第一焦点 10处； 远光聚光器 4设置在近光线路板 1 的前侧位置， 且远光 聚光器出光面 4d位于近光反射镜 2的第二焦点 1 1 处， 远光聚光器出光面 4d 的上侧边线 401 的位置与近光反射镜 2的第二焦点 1 1 在前后方向上的距离 2mm, 可选的， 远光聚光器出光面 4d 的上侧边线 401 的位置与近光反射镜 2 的第二焦点 1 1 在前后方向上的距离为 0mm， 也即近光反射镜 2的第二焦点 1 1 位于远光聚光器出光面 4d的上侧边线 401 上， 此种结构设置能够提高光学效 率。 远光聚光器出光面 4d的上侧边线 401 具有近光截止线的形状以配置成截 取近光光线从而形成近光光形； 透镜 6设置在远光聚光器 4的前侧位置， 配置 成接收由远光聚光器 4的远光聚光器出光面 4d传播出来的光线。 近光光源 1 a 发出的光线经近光反射镜 2反射后， 经远光聚光器出光面 4d上方射向透镜 6, 并经透镜 6折射后形成近光光形； 远光光源 3a发出的光线经远光聚光器 4折 射以及反射后由远光聚光器出光面 4d射出并射向透镜 6， 经透镜 6折射后形 成远光光形 H i。 由此分析可知， 本公开提供的车灯模组中， 将近光反射镜 2 设置为近光功能的一级光学元件，且将远光聚光器 4设置为远光功能的一级光 学元件， 能够获得良好的近光均匀性， 良好的远光照明性能， 以及良好的远光 和近光衔接性能； 同时， 车灯模组零件构成数量少， 结构简单， 成本较低； 通 过近光反射镜 2和远光聚光器 4的结构设计，使得车灯模组的光学元件整体占 用空间体积也较小。 综上， 本公开提供的车灯模组通过光学元件的合理设置， 以及各个光学元件的参数设计， 能够使得光形的均勾性以及近光可视性均优 良， 且车灯模组结构相对简单、 重量较轻、 体积较小和成本较低， 具有很好的 综合性能。
此处需要补充说明的是， 本公开中的前后方向为车灯模组的出光方向， 即 透镜 6的光轴方向； 上下方向和重力方向相同。 此外， 近光的一级光学元件选 用反射镜的原因是反射镜的光形均勾性比聚光器好，对反射镜进行合理的光学 面设计， 其在近光可视性上也可以较好； 远光的一级光学元件为聚光器， 在车 灯模组总成的零件构成中为远光聚光器 4, 远光的一级光学元件选用聚光器的 原因是聚光器做远光的光学性能比反射镜高。
本公开中，远光聚光器出光面 4d的上侧边线 401 具有近光截止线的形状， 配置成截取近光光线从而形成近光光形， 现有技术中， 一般近光截止线的形成 都是要有截止线形状的结构将光线进行截取而成，本公开中将近光截止线的形 状做在远光聚光器 4上， 具有光学元件之间的装配精度高、 车灯模组结构简单 以及成本低等优点。
如图 4所示， 可选的， 近光反射镜 2大致呈弧形板状， 结构规整， 便于加 工制造。 近光反射镜 2具有相对的内凹面 21 以及外凸面 22， 内凹面 21 朝向 透镜 6。 近光反射镜 2的内凹面 21上设置有第一近光反射镜反射面区域 2a和 第二近光反射镜反射面区域 2b， 以图 4所示的视角为例， 第一近光反射镜反 射面区域 2a设置在近光反射镜 2的下侧位置， 换句话说， 内凹面 21 包括相连 的第一近光反射镜反射面区域 2a和第二近光反射镜反射面区域 2b， 第一近光 反射镜反射面区域 2a远离第二近光反射镜反射面区域 2b的一侧延伸至近光反 射镜 2的一边緣， 第二近光反射镜反射面区域 2b远离第一近光反射镜反射面 区域 2a的一侧延伸至近光反射镜 2的相对的另一边緣。 可选的， 第一近光反 射镜反射面区域 2a相对于第二近光反射镜反射面区域 2b沿内凹面 21 向外凸 面 22的方向凹陷， 也即， 近光反射镜 2的内凹面 21形成台阶结构， 第一近光 反射镜反射面区域 2a位于台阶结构较低的一侧， 第二近光反射镜反射面区域 2b位于台阶结构较高的一侧， 第一近光反射镜反射面区域 2a和第二近光反射 镜反射面区域 2b之间被阻断， 相互之间不易产生干扰， 便于光线的传播。 可 选的，第一近光反射镜反射面区域 2a和第二近光反射镜反射面区域 2b均可以 为椭圆面， 且第一近光反射镜反射面区域 2a的面积占近光反射镜 2的总面积 的 10%及以下， 可选的， 第一近光反射镜反射面区域 2a的面积占近光反射镜 2 的总面积的 7% ; 其中， 总面积是指内凹面 21 的表面积。
可选的， 第一近光反射镜反射面区域 2a和第二近光反射镜反射面区域 2b 的表面均作镀铝处理， 镀铝反射率 0. 8。 请参阅图 8， 第一近光反射镜反射 面区域 2a的第一焦点 10设于近光光源 1a的光学中心； 第一近光反射镜反射 面区域 2a的第二焦点 1 1 设于远光聚光器出光面 4d上， 且远光聚光器出光面 4d的上侧边线 401 的位置和第一近光反射镜反射面区域 2a的第二焦点 1 1 在 前后方向上的距离 2mm， 可选的， 远光聚光器出光面 4d的上侧边线 401 的位 置与近光反射镜 2的第二焦点 1 1 在前后方向上的距离为 0mm， 第一近光反射 镜反射面区域 2a的第二焦点 1 1位于远光聚光器出光面 4d的上侧边线 401上， 这样设置能够提高光学效率， 还能够提高近光光形的 75R 及其附近的光形亮 度； 请参阅图 9, 近光光源 1a发出的光线经第一近光反射镜反射面区域 2a反 射后， 经远光聚光器出光面 4d上方射向透镜 6， 经透镜 6折射后形成第一近 光光形区域 Lo1， 第一近光光形区域 Lo1 为近光截止线下方 75R法规测试点及 其附近区域， 能够提高近光可视性； 近光光源 1a发出的光线经第二近光反射 镜反射面区域 2b反射后， 经远光聚光器出光面 4d上方射向透镜 6， 经透镜 6 折射后形成第二近光光形区域 Lo2， 第二近光光形区域 Lo2为近光截止线下方 的展宽区域， 第二近光光形区域 Lo2和第一近光光形区域 Lo1部分重合， 能够 提高近光照射范围。 本公开中， 可选的， 第一近光光形区域 Lo1 全部落入第二 近光光形区域 Lo2内。
此处需要补充说明的是， 第一近光反射镜反射面区域 2a设置在近光反射 镜 2的下侧位置， 第一近光反射镜反射面区域 2a可以为椭圆面， 且占近光反 射镜 2的总面积的 10%及以下， 可选的， 第一近光反射镜反射面区域 2a的面 积占近光反射镜 2的总面积的 7% ; 之所以将近光反射镜 2的反射面做上述设 计， 是因为靠近近光光源 1a的近光反射镜 2下侧的反射面区域主要是形成近 光 75R及其附近区域光形的， 而其他反射面区域主要是形成近光展宽光形的， 将第一近光反射镜反射面区域 2a靠近近光光源 1a设置且对其面积进行限定， 可以提高近光 75R及其附近区域光形的亮度， 从而提高近光可视性。
可选的， 近光光源 1a包括 LED， 且近光光源 1a的底面和前后方向成夹角 a， 换句话说， 以图 4的视角为例， 近光光源 1a包括平行的底面和出光面 12, 出光面 12与水平面之间的夹角为 a。本公开中， a＜30° ，可选的， a为 21 ° ; 近光反射镜 2与水平面之间的夹角和该夹角 a相等。 将近光光源 1 a及近光反 射镜 2向上倾斜一定角度， 不仅可以使得更多的光线照射进入透镜 6, 提高近 光的光学效率， 还可以改善近光的截止线色散情况。
可选的， 第一近光反射镜反射面区域 2a作抛光处理； 第二近光反射镜反 射面区域 2b不作抛光处理。 这样设计的原因是第一近光反射镜反射面区域 2a 是为了提高近光可视性而设置的， 抛光处理可以进一步提高其可视性， 而第二 近光反射镜反射面区域 2b是为了近光展宽的光形而设置的， 不作抛光处理反 而可以优化其展宽光形的均勾性， 使驾驶员获得良好的视觉体验。
如图 5 -图 8所示， 可选的， 远光聚光器 4的光学面包括： 远光聚光器聚 光杯结构 4a、 远光聚光器全反射面 4b、远光聚光器上表面 4c和远光聚光器出 光面 4d ; 远光聚光器全反射面 4b、远光聚光器上表面 4c和远光聚光器出光面 4d依次连接， 远光聚光器聚光杯结构 4a位于远光聚光器全反射面 4b的下方。 远光聚光器聚光杯结构 4a包括： 远光聚光器聚光杯结构的反射面 4a-1、 远光 聚光器聚光杯结构的内折射面 4a-2 和远光聚光器聚光杯结构的内中心面 4a-3,远光聚光器聚光杯结构的反射面 4a-1 为远光聚光器聚光杯结构 4a的外 周壁， 远光聚光器聚光杯结构 4a的底部设有凹槽 41 , 远光聚光器聚光杯结构 的内折射面 4a-2为凹槽 41 的槽周壁，远光聚光器聚光杯结构的内中心面 4a-3 为凹槽 41 的槽底壁。
远光聚光器全反射面 4b设置在远光聚光器聚光杯结构 4a的上侧位置，且 和前后方向相对倾斜设置， 换句话说， 远光聚光器全反射面 4b与水平面相对 倾斜设置， 可选的， 30 ° 倾斜角 60 ° ， 可选的， 远光聚光器全反射面 4b 与水平面之间的倾斜角为 45° ， 应当理解， 远光聚光器全反射面 4b与水平面 之间的倾斜角还可以为 30 ° 或者 60度。 可选的， 远光聚光器全反射面 4b与 水平面之间的倾斜角为 30 ° 倾斜角 45° 或者 45° 倾斜角 60° 。 远光 聚光器上表面 4c沿前后方向设置，且远光聚光器上表面 4c相对的两侧分别连 接远光聚光器全反射面 4b和远光聚光器出光面 4d ; 远光聚光器出光面 4d可 以为弧面， 且远光聚光器出光面 4d 所在圆的直径的范围为： 30mm 直径 200mm，可选的，远光聚光器出光面 4d所在圆的直径为 30mm、 100mm或者 200mm, 或者， 远光聚光器出光面 4d所在圆的直径为 30mm＜直径＜ 100mm， 或者， 远 光聚光器出光面 4d所在圆的直径为 100mm 直径 200mm。 如图 1 1 所示， 图 中示出了远光光形的示意图。 远光光源 3a 发出的光线经聚光器聚光杯结构 4a折射以及反射后向上在远光聚光器 4 内传播， 然后经远光聚光器全反射面 4b全反射后， 再在远光聚光器上表面 4c的下方继续在远光聚光器 4内传播， 经远光聚光器出光面 4d折射出后， 射向透镜 6， 经透镜 6折射后形成远光光 形 H i。
本公开中， 通过在远光聚光器 4上设置一个远光聚光器全反射面 4b， 使 得远光聚光器 4大致呈 “L” 形的结构， 可以节省模组前后方向的尺寸空间， 以及充分将近光光源 1 a和远光光源 3a分离开，较远的热源距离大大改善了散 热性能。
远光聚光器 4的形状为 “L” 形， 使得远光和近光的热源距离分开较远， 大大提高了车灯模组的散热性能。
可选的， 如图 5和图 7所示， 远光光源 3a包括 LED, 且远光光源 3a的颗 数 2， 可选的， 远光光源 3a的颗数为 3颗； 远光聚光器聚光杯结构 4a的数 量等于远光光源 3a的数量， 且设置在对应的远光光源 3a的上方。 例如， 本公 开中， 远光光源 3a的数量为 3颗， 远光聚光器聚光杯结构 4a的数量为 3个， 3个远光聚光器聚光杯结构 4a和 3颗远光光源 3a—一对应设置， 每个远光光 源 3a位于对应的远光聚光器聚光杯结构 4a的凹槽 41 的槽口处。
可选的， 远光聚光器全反射面 4b和 /或远光聚光器上表面 4c上设置有增 反膜， 从而有效提高光线照射到其表面的反射率， 进一步提高车灯模组的光学 效率； 远光聚光器出光面 4d上设置有增透膜， 从而有效提高光线经过远光聚 光器出光面 4d的透过率， 进一步提高车灯模组的光学效率。
可选的， 远光聚光器上表面 4c上作镀铝处理， 且镀铝反射率 0. 8, 从而 有效提高近光光线照射到远光聚光器上表面 4c的反射率， 进一步提高车灯模 组的光学效率。
请参阅图 2， 本公开中， 本公开提供的车灯模组还可以包括： 散热器 5、 透镜支架 7和模组支架 8 ; 散热器 5的散热片 51 的单面或双面上设置有凹凸 不平或者 /和波浪状的曲面 51 1 ; 透镜支架 7配置成安装透镜 6, 但不排除其它 将透镜 6设计在散热器 5或者其他零件上的安装结构；模组支架 8配置成连接 散热器 5和透镜支架 7， 且模组支架 8可以和车灯的灯体连接， 通过模组支架 8的结构设计， 可以从灯体的后方， 单独将散热器 5及其上的零件总成拆解下 来， 方便更换光源。
可选的， 散热器 5设置有第一安装面 52和第二安装面 53, 第二安装面 53 与水平面平行， 第一安装面 52与第二安装面 53具有夹角， 夹角的范围为 0° -30° ， 可选的， 第一安装面 52与第二安装面 53之间的夹角为 30 ° 。 可选的， 第一安装面 52和第二安装面 53之间通过连接面 54连接，连接面 54竖向设置， 第一安装面 52和第二安装面 53没有直接连接， 且具有一定的高度差， 近光线 路板 1设置于第一安装面 52上， 远光线路板 3设置于第二安装面 53上， 使得 近光线路板 1上的近光光源 1 a与远光线路板 3上的远光光源 3a之间具有高度 差， 充分将近光光源 1 a和远光光源 3a分离开， 较远的热源距离大大改善了车 灯模组的散热性能。 安装时， 近光线路板 1和远光线路板 3的相对位置确定， 安装完成后， 即确定了近光光源 1 a与水平面之间的角度， 且位置准确， 便于 安装， 提高安装效率。
