相关申请的交叉引用
本申请要求2020年12月22日提交的中国专利申请202011534817.9的权益，该申请的内容通过引用被合并于本申请。
技术领域
本发明涉及车灯，具体地，涉及一种ADB车灯模组。本发明还涉及一种车灯及一种车辆。
背景技术
远光灯能够提供亮度高，照射范围远的照明空间，给驾驶人在光线差、车辆少的道路以较高的速度行驶时提供更深远的视野。但在道路上车辆较多时，或者在会车或跟车时不及时切换为近光，远光照明会引起道路上其他车辆的驾驶人炫目，在将远光切换为近光时也会导致车前视野变小，容易引发交通事故。
自适应远光(ADB)由多个远光光源发出的光线共同提供远光照明，每个远光光源发出的光线形成的照明区域称为一个像素，多个像素相组合形成远光光形。ADB系统能够根据前方车辆的位置和距离控制远光光形中相应的像素熄灭，从而避免了远光照明造成前方车辆或对方车辆驾驶人眩目，提高驾驶的安全性。
一种现有的ADB车灯模组如图1所示，包括多个远光光源1、微透镜2、柱面透镜31和透镜4。多个远光光源1左右排列，每个远光光源1形成的像素左右排列，拓展了远光光形宽度方向上的照明范围。柱面透镜31将远光光源1发出的光线在上下方向上进行扩散，形成如图2所示的在上下方向上均被拉长的像素光形，拓展了远光光形高度方向上的照明范围。但该技术方案使得远光光形的下边界过低，车辆近前处照明亮度过高，影响驾驶人对远方照明区域的观察效果。同时照明范围的扩散降低了像素光形中间区域的照度，影响了远光照明效果。
发明内容
本发明所要解决的技术问题是提供一种ADB车灯模组，该车灯模组形成的像素光形合理，像素中间区域亮度高。
本发明进一步所要解决的技术问题是提供一种车灯，该车灯的远光照明光形更合理，远光照明效果好。
本发明还要解决的技术问题是提供一种车辆，该车辆的车灯远光照明光形合理，远光照明 效果好
为了解决上述技术问题，本发明一方面提供了一种ADB车灯模组，包括多个远光光源、微透镜、半柱面透镜和透镜；多个所述远光光源线性排列且适于独立控制亮灭，所述微透镜上包括线性排列的多个聚光单元，每个所述聚光单元与一个所述远光光源对应设置；所述半柱面透镜为柱面轴与所述远光光源排列方向一致的柱面透镜的下半部分，所述半柱面透镜位于所述微透镜的下半部的前方，所述透镜位于所述半柱面透镜的前方。
优选地，所述微透镜包括微透镜入光面、微透镜出光面、微透镜上侧面和微透镜下侧面；所述微透镜入光面、微透镜上侧面和微透镜下侧面均为平面，各所述聚光单元所对应的微透镜出光面部分分别形成一个向前凸出的曲面，且各曲面的左右宽度由内侧向外侧逐渐减小。通过该优选技术方案，光线能够从微透镜入光面进入微透镜，经微透镜的汇聚后从微透镜出光面射出。微透镜中各聚光单元所对应的曲面的左右宽度由内侧至外侧逐渐减小的结构能够使得各远光光源所形成的像素光形的宽度由内侧至外侧逐渐增大，从而使得远光照明光形在车辆正前方的位置具有较高的像素分辨率，而在车辆的外侧位置的像素分辨率较低，在实现ADB功能的同时减轻照明暗区对路面照明的影响。上侧面和下侧面能够限制远光光源的照明范围。
进一步优选地，所述微透镜上侧面为前部向上倾斜的平面，所述微透镜下侧面为前部向下倾斜的平面。在该优选技术方案中，微透镜上侧面和微透镜下侧面的倾斜设置能够形成竖直平面上前宽后窄的喇叭形结构，通过调节微透镜上侧面和微透镜下侧面的倾斜度能够调节所形成的像素光形的高度范围，提高像素光形中间区域的照度。
优选地，所述半柱面透镜为入光面为平面的平凸柱面透镜。通过该优选技术方案，半柱面透镜平面的入光面能够减少对入光光线的反射，提高远光光效。
优选地，各所述聚光单元的光轴均位于所述半柱面透镜的光轴面上。在该优选技术方案中，通常可以将半柱面透镜视为由柱面透镜沿光轴面剖切形成，通过聚光单元的光轴的光线也通过半柱面透镜的光轴面，而光线通过透镜的光轴或光轴面时不产生折射，这就能够使经过半柱面透镜光轴面上下的光线平滑过渡。
进一步优选地，各所述远光光源的发光中心均位于所述透镜的光轴下方设定距离。通过该优选技术方案，远光光源发出的光线经过微透镜和半柱面透镜后所形成的像素光形的整体偏向透镜的下部，经透镜投射后所形成的像素光形整体上移，能够进一步抬高像素光形的下边界，并使得像素光形的中心上移。
优选地，所述远光光源、微透镜和半柱面透镜整体在前后方向竖直平面上绕远光光源的发光中心向下旋转设定角度。在该优选技术方案中，远光光源所发出的光线经微透镜和半柱面透镜的汇聚和折射，形成一个向下呈设定角度倾斜的照射方向，经透镜的折射后，所形成的像素光形整体上移。
优选地，本发明的ADB车灯模组还包括点亮光源和点亮光学元件，所述点亮光学元件设置在所述点亮光源与所述透镜之间，以能够收集所述点亮光源发出的光线，经所述点亮光学元件的传输后射向所述透镜，形成点亮光线。在该优选技术方案中，点亮光源发出的光线能够照射到点亮光学元件上，经过点亮光学元件的折射和传输，照射到透镜上，形成点亮光线，以形成近光照明模式下透镜仍能点亮的外观效果。
进一步优选地，所述点亮光学元件包括点亮入光面、点亮通光部和点亮出光面，所述点亮入光面为平面，位于所述点亮光学元件的后端，所述点亮出光面为向前凸出的圆弧面，位于所述点亮光学元件的前端，所述点亮通光部位于所述点亮入光面与所述点亮出光面之间，所述点亮通光部的两侧形成为相交于所述点亮光源后方的平面。通过该优选技术方案，点亮光源发出的光线能够从点亮光学元件后端的点亮入光面进入点亮光学元件，经过点亮光学元件的传输，从点亮出光面射出，照射到透镜上。向前凸出的圆弧面形的点亮出光面能够对光线进行散射，使得点亮光源发出的光线能够照射到狭长的透镜的整个表面。
进一步地，所述点亮出光面上设置有竖向凹、凸条纹。在该优选技术方案中，点亮出光面上的竖向凹、凸条纹能够对通过点亮出光面射出的光线形成散射，提高点亮光线的均匀性。
优选地，所述点亮光学元件还包括点亮安装部，所述点亮安装部设置在所述点亮通光部的两侧，所述点亮通光部与所述点亮安装部之间设置有空气间隙。在该优选技术方案中，通过点亮安装部能够对点亮光学元件进行安装固定，空气间隙能够对照射到点亮通光部的侧壁上的光线形成全反射，限制点亮光线的照射范围，并能够提高点亮光线的光效。
优选地，本发明的ADB车灯模组还包括光学单元支架，所述微透镜一体成型于所述光学单元支架的中部，所述光学单元支架的上部设置有点亮光学元件安装板，所述光学单元支架的下部设置有用于安装所述半柱面透镜的柱面透镜安装孔。通过该优选技术方案，微透镜一体成型于光学单元支架中部的结构使得微透镜与光学单元支架之间的定位更精确，结构稳定性也更高。点亮光学元件安装板和柱面透镜安装孔的设置使得点亮光学元件和半柱面透镜均能够安装在光学单元支架上，提高微透镜、柱面透镜以及点亮光学元件相互之间定位的准确性。
本发明第二方面提供了一种车灯，所述车灯包括本发明第一方面提供的ADB车灯模组。
本发明第三方面提供了一种车辆，包括本发明第二方面提供的车灯。
通过上述技术方案，本发明的ADB车灯模组，线性排列的多个远光光源能够各自独立地发光和熄灭，分别形成远光照明光形中的一个像素，形成ADB功能。微透镜上的多个聚光单元能够分别对对应的远光光源发出的光线进行汇聚，经透镜投射后形成像素光形。半柱面透镜能够对像素光形的一半进行拉长，经过透镜的投射后形成上边界偏转角度较大，下边界偏转角度较小的像素光形，扩展了像素光形在高度方向上的照射范围，抬高了像素光形的下边界，所形成的远光照明光形的照明范围更加合理，并提高了像素光形中间区域的亮度，远光照明效果更好。由于本 发明的车灯使用了本发明的ADB车灯模组，本发明的车辆使用了本发明的车灯，也具有上述优点。

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，本发明的保护范围并不局限于下述的具体实施方式。
如图3至图8所示，本发明的ADB车灯模组的一个实施例，包括多个远光光源1、微透镜2、半柱面透镜3和透镜4。多个远光光源1排列成一条直线或者曲率较小的曲线，各远光光源1发出的光线能够分别形成一个照明区域，各个远光光源1所形成的照明区域相互组合形成一个整体的远光照明光形，每个远光光源1所形成的照明区域称为远光照明光形的一个像素。各个远光光源1能够独立地控制亮灭，也就能够独立地控制远光照明光形中每个像素的明暗，形成ADB功能。微透镜2上包括多个线性排列的聚光单元，聚光单元形成为凸透镜结构，每个聚光单元与一个远光光源1相对应，能够对每个远光光源1发出的光线进行汇聚，形成具有明显边界的像素。半柱面透镜3为柱面透镜的一半，当然，本发明中所说的半柱面透镜3为柱面透镜的一半并不要求其精确性，半柱面透镜3完全可以是柱面透镜近似的一半。具体地，柱面透镜为入光面和/或出光面为柱面的凸透镜，柱面为由弧线沿直线方向平行移动所形成的曲面，弧线的弦移动形成的平面可以称之为弦平面，弦的中点移动所形成的直线称为柱面轴。半柱面透镜3由柱面透镜沿垂直于弦平面的方向通过柱面轴等量剖分形成。半柱面透镜3的柱面轴与远光光源1排列方向一致，且其剖分面向上设置。半柱面透镜3设置于微透镜2前方、相对于微透镜2下半部分的位置，远光光源1发出的光线经微透镜2的汇聚后，从微透镜2下半部分射出的光线射向半柱面透镜3，经半柱面透镜3的折射后射向设置在半柱面透镜3前方的透镜4，从微透镜2上半部分射出的光线直接射向透镜4，经透镜4的投射后，形成如图9所示的像素光形。从图9可以看出，像素光形上边界52的偏角较大，而像素光形下边界53的偏角较小，像素光形的上半部分被明显拉长，形成了像素光形在高度方向上较大的照射范围；像素光形的下半部分未被拉长，因而像素光形的下边界位置较高，避免了远光照明光线照射在车辆前方较近位置而影响对远方路面的观察效果，并提高了像素光形中间区域54照明亮度。
通过图10和图12所示的ADB车灯模组能够进一步说明半柱面透镜3的作用。如图10所示，远光光源1发出的光线经过微透镜2的汇聚后射向柱面透镜31，经柱面透镜31的折射后射向透镜4，经过透镜4的投射，形成如图11所示的像素光形。在如图11所示的像素光形中，像素光形上边界52被明显抬高，像素光形下边界53被对称压低，像素光形的上下部分被对称拉长，形成了像素光形在高度方向上更大的照射范围，像素光形中最亮部位的照度为46.5lx。在如图12所示的ADB车灯模组中，在保持如图10所示的ADB车灯模组中其他设置不变的情况下，仅将柱面透镜31替换为半柱面透镜3，半柱面透镜3仅对从微透镜2下半部分射出的光线起到折射作用，最终形成如图13所示的像素光形。在如图13所示的像素光形中，像素光形上边界52被 明显抬高，像素光形下边界53压低较小，像素光形的上半部分被明显拉长，而像素光形的下半部分未被明显拉伸，所形成的像素光形上部的照明范围更大，下部照明区域的下边界明显提高，使得远光光线更多地照射到距离车辆较远的区域，避免照射在车辆近前方的高亮度光线影响驾驶人对远方照明区域的观察效果。此时，像素光形中最亮部位的照度为79.9lx，像素光形的中心区域亮度明显提高。
在本发明的ADB车灯模组的一些实施例中，如图3-图8所示，微透镜2包括微透镜入光面21、微透镜出光面22、微透镜上侧面23和微透镜下侧面24。微透镜入光面21、微透镜上侧面23和微透镜下侧面24均为一个平面，也就是说，微透镜2上各聚光单元的入光面形成为同一个平面，各聚光单元的上侧面和下侧面也分别形成为同一个平面；微透镜出光面22由多个向前凸出的曲面组合而成，每个聚光单元对应着一个向前凸出的曲面，使得各聚光单元形成为一个凸透镜。曲面的形状可以根据所需要的像素光形的形状自由设置，具体可以设置为球面，也可以设置为椭球面或者自由曲面等。微透镜2上位于内侧的聚光单元所对应的曲面的左右宽度大于位于外侧的聚光单元所对应的曲面的左右宽度，也就是说，位于内侧的远光光源1之间的间距较大，而位于外侧的远光光源1之间的间距较小。这样，经过透镜4的投射后，位于车辆内侧，也就是靠近车辆正前方的像素光形的宽度较小，而位于车辆外侧，也就是远离车辆正前方的像素光形的宽度较大。此时，所形成的远光照明光形靠近车辆正前方的部分具有更高的像素分辨率，而远光照明光形位于车辆外侧的部分像素分辨率较低。在实现ADB功能，熄灭某个远光光源1时，在车辆正前方形成的照明暗区较小，而在车辆侧方形成的照明暗区较大，这样能够减小照明暗区对驾驶安全的影响。
作为本发明的ADB车灯模组的一种具体实施方式，如图18所示，微透镜上侧面23为前部向上倾斜的平面，微透镜下侧面24为前部向下倾斜的平面，使得微透镜2的后部高度较小而前部高度较大。微透镜上侧面23和微透镜下侧面24延伸后相交于远光光源1的后方，这样的结构使得远光光源1发出的光线能够更多地在微透镜上、下侧面处产生全反射，并使得更多的光线能够参与形成像素光形，远光光源1的光效更高，所形成的像素光形的亮度更高。当然，也可以将微透镜上侧面23和微透镜下侧面24中的一个倾斜设置、另一个平直设置，但这样设置的效果要稍差一些。
通过图19和图21所示的ADB车灯模组能够说明本实施例中的微透镜上、下侧面的作用。如图19所示的ADB车灯模组，微透镜2上的微透镜上侧面23和微透镜下侧面24平行设置，远光光源1发出的光线经过微透镜2的汇聚，部分光线经过半柱面透镜3的折射后射向透镜4，经过透镜4的投射形成如图20所示的像素光形。远光光源1发出的部分光线照射到平行设置的微透镜上侧面23或微透镜下侧面24，经微透镜上侧面23或微透镜下侧面24的反射后从微透镜出光面22射出，参与形成像素光形。平行设置的微透镜上侧面23和微透镜下侧面24使得远光 光源1照射到微透镜2的上、下侧面上的光线较多，而照射到微透镜2的上、下侧面上的光线经过上、下侧面的反射会产生一定的损失，因此，所形成的像素光形的亮度较低。如图20所示，像素光形中照度的最高值为79.9lx。图21所示的ADB车灯模组仅将如图19所示的ADB车灯模组中的微透镜2替换为微透镜上侧面23和微透镜下侧面24倾斜设置的微透镜2，由于微透镜上侧面23和微透镜下侧面24由后向前延伸的过程中分别向上和向下倾斜，远光光源1发出的光线更多直接地照射到微透镜出光面22上。照射到微透镜上侧面23和微透镜下侧面24上的光线的入射角也更大，光线的反射率更高，更容易形成全反射。因此，所形成的像素光形的亮度较高。其形成的像素光形如图22所示，像素光形中照度的最高值为81.2lx，高于图20中像素光形中的最高照度。
在本发明的ADB车灯模组的一种具体实施方式中，如图3-图8所示，半柱面透镜3为入光面为平面的平凸柱面透镜。使用入光面为平面的半柱面透镜3，加工更为方便，而且，相较于双凸柱面透镜，平面的入光面对入射光的反射更少，光效更高。在本发明的ADB车灯模组中，半柱面透镜3设置在透镜4的偏内侧位置，因而，在用于左、右车灯的ADB车灯模组中，需要将半柱面透镜3设置在不同的位置。作为一种优选方案，可以使用长度更长的半柱面透镜3，使得半柱面透镜3的位置覆盖左、右车灯中所需的位置。这样，左、右车灯的车灯模组可以使用相同的半圆柱透镜3和透镜4，仅替换不同的微透镜2和光源1就可以完成左、右车灯的转换，ADB车灯模组的通用性更高。
在本发明的ADB车灯模组的一些实施例中，如图3-图8所示，远光光源1的发光中心均位于各自对应的聚光单元光轴25上。由于每个聚光单元均为一个凸透镜结构，每个聚光单元均具有一个光轴，即聚光单元光轴25。将远光光源1设置在聚光单元光轴25上，从远光光源1的中心发出的沿聚光单元光轴25射出的光线通过聚光单元时不发生偏折，且远光光源1发出的光线在聚光单元光轴25的周围均匀分布。同时，各聚光单元光轴25均设置在半柱面透镜3的光轴面上。平行光线以垂直于半柱面透镜3上柱面的弦平面的方向射向半柱面透镜3时，会在半柱面透镜3的另一侧汇聚成一条平行于半柱面透镜3的柱面轴的焦线，该焦线和柱面轴所在的平面称为半柱面透镜3的光轴面。聚光单元的光轴设置在半柱面透镜3的光轴面上，远光光源1发出的光线通过聚光单元射出后，位于光轴面下方的一半通过半柱面透镜3，位于光轴面上方的一半不通过半柱面透镜3，形成上半部分经过拉伸，下半部分没有经过拉伸的像素光形。远光光源1发出的光线的一半经过半柱面透镜3在上下方向上的拉伸，照射的高度范围更广；另一半光线没有经过半柱面透镜3的拉伸，照射亮度更高。
在本发明的ADB车灯模组的一些实施例中，如图3-图8所示，各个远光光源1的发光中心均设置在对应的聚光单元光轴25上，且聚光单元光轴25位于透镜光轴41的下方，透镜光轴41距离各聚光单元光轴25在竖直方向上的距离为L。需要说明的是，各远光光源1的排列方向也 可以不是水平方向，此时，以各远光光源1所对应的聚光单元光轴25在竖直方向上距离透镜光轴41的平均距离控制为L。将聚光单元光轴25设置在透镜光轴41的下方，能够使得远光光源1发出的光线照射到透镜4上的位置整体下移，经过透镜4的投射后，所形成的像素光形的位置整体向上偏移，所形成的远光光形的位置更加合理。聚光单元光轴25偏离透镜光轴41的垂直距离L通常设置为0.2-1mm，在本实施例中设置为0.5mm。
在本发明的ADB车灯模组的一些实施例中，如图3-图8所示，远光光源1、微透镜2和半柱面透镜3作为一个整体在前后方向的竖直平面上绕远光光源1的发光中心旋转一个角度α，使得半柱面透镜3所在的一方向下偏移。也就是说，聚光单元光轴25的前部绕远光光源1的发光中心向下旋转角度α，到达聚光单元光轴旋转位25’。如果各个远光光源1的发光中心不在同一个左右方向的水平直线上，可以根据需要选取一个远光光源1，以其发光中心所在的左右方向的水平直线作为旋转轴。旋转的角度α可以根据实际所要实现的光形边界进行设定，通常设定在10°以下，在本实施例中设置为4°。
通过图14和图16所示的ADB车灯模组能够说明本实施例中远光光源1和微透镜2旋转的作用。在如图14所示的ADB车灯模组中，远光光源1的发光中心、微透镜2的一个聚光单元的中心和透镜4的中心设置在同一个水平面上，也就是说，微透镜2的该聚光单元的光轴和透镜4的光轴相重合，远光光源1的发光中心设置在微透镜2的该聚光单元和透镜4的光轴上。此时，远光光源1发出的光线所形成的像素光形如图15所示。在图15中，像素光形的中心位于投射屏幕的H轴51上，像素光形上边界52和像素光形下边界53相对于H轴51相对称。图16所示的ADB车灯模组为保持图14所示的ADB车灯模组中的透镜4的位置不变，将图14所示的ADB车灯模组中的远光光源1和微透镜2绕远光光源1的发光中心，逆时针旋转一个角度α形成。图16所示的ADB车灯模组所形成的像素光形如图17所示。在图17中，像素光形整体向上偏移，使得像素光形的中心位于H轴的上方，像素光形上边界52和像素光形下边界53的位置均向上抬高。
在本发明的ADB车灯模组的一些实施例中，如图23-图29所示，本发明的ADB车灯模组还包括点亮光源11和点亮光学元件6。点亮光源11设置在透镜4的后方，点亮光学元件6设置在点亮光源11与透镜4之间。点亮光源11发出的光线经过点亮光学元件6的收集、折射和传输后射向透镜4，形成通过透镜4的出光面射出的点亮光线，使得该ADB车灯模组在近光照明模式下远光光源1关闭时，透镜4的外观仍能呈现出点亮状态，提高车辆的视觉效果。
在本发明的ADB车灯模组的一些实施例中，如图23-图29所示，点亮光学元件6包括点亮入光面61、点亮通光部62和点亮出光面63。点亮入光面61为平面，平面的点亮入光面61入射光路简单，易于控制，且制造方便。点亮入光面61位于点亮光学元件6的后端接近点亮光源11处，点亮出光面63为位于点亮光学元件6前端的向前凸出的圆弧面，能够对通过点亮出光面63 射出的光线形成散射，以能够照亮整个透镜4的入光面。点亮通光部62位于点亮入光面61与点亮出光面63之间，以将通过点亮入光部61射入的光线传输到点亮出光面63。点亮通光部62的两侧形成为平面的导光边界，点亮通光部62两侧的导光边界平面相交于点亮光源11的后方，通过点亮入光面61导入的光线能够更多地不经过侧边界的反射照射到整个点亮出光面63。两侧导光边界平面之间的夹角β可以设置为20-50°。在本实施例的优选方案中设置为30-35°。
作为本发明的ADB车灯模组的一种具体实施方式，如图23-图25所示，在点亮出光面63上设置有竖向凹、凸条纹，竖向凹、凸条纹在点亮出光面63上均匀分布。竖向凹、凸条纹能够对通过点亮出光面63的光线形成散射，使得照射向透镜4的点亮光线分布更加均匀。
在本发明的ADB车灯模组的一些实施例中，如图23-图29所示，点亮光学元件6还包括点亮安装部64。点亮安装部64设置在点亮通光部62的外部，点亮通光部62的两侧。在点亮通光部62与点亮安装部64之间设置有空气间隙65，使得空气间隙65形成为点亮通光部62与点亮安装部64的分界。从点亮通光部62中通过的光线照射到位于点亮通光部62左右侧壁的空气间隙65的侧壁时能够产生全反射反射回点亮通光部62中，从而提高照射到点亮出光面63的光线的量，提高点亮光学元件6的光效。
作为本发明的ADB车灯模组的一种具体实施方式，如图30和图31所示，本发明的ADB车灯模组还包括光学单元支架7。微透镜2可以单独成型安装在光学单元支架7的中部，微透镜2还可以与光学单元支架7通过嵌件注塑或者双色注塑的方式一体成型在光学单元支架7的中部。在光学单元支架7上微透镜2出光面处的上下侧位置还可以设置有倾斜面77，倾斜面77的设置能够使得通过微透镜2射出的光线能够更多地射向透镜4。光学单元支架7的上部还设置有用于安装点亮光学元件6的点亮光学元件安装板71，点亮光学元件安装板71上还设置有点亮单元定位销73和点亮单元安装孔74。点亮光学元件6的点亮安装部64上设置有安装孔和定位孔，并通过该定位孔与点亮单元定位销73相配合进行定位，通过螺钉穿过点亮安装部64上的安装孔旋合在点亮单元安装孔74中，将点亮光学元件6安装在点亮光学元件安装板71上。光学单元支架7的下部还设置有用于安装半柱面透镜3的柱面透镜安装孔72和柱面透镜定位销75，半柱面透镜3上设置有安装孔和定位孔，并通过该定位孔与柱面透镜定位销75相配合进行定位、通过该安装孔与柱面透镜安装孔72的配合将半柱面透镜3安装在光学单元支架7上微透镜2的前方。远光光源1和点亮光源11设置在线路板8上，作为一种安装方式，螺钉依次穿过散热器9上的安装孔、线路板8上的安装孔和支架安装孔76并与透镜支架42上的螺纹孔螺纹连接，以将透镜支架42、光学单元支架7、线路板8和散热器9固定在一起，透镜4安装在透镜支架42的前端，形成本发明的ADB车灯模组。
通过上述技术方案，本发明的ADB车灯模组，微透镜2的设置能够对远光光源1发出的光线进行汇聚，使得更多的光线能够照射到透镜4上，并能够与透镜4相配合优化所形成的像素光 形的形状。半柱面透镜3的设置能够对远光光源1发出的下部的光线在竖直方向上进行折射，使得远光光源1形成的像素光形的上部得到拉伸，提高了像素光形上边界52的偏转角度，得到上边界偏转角度较大，像素光形下边界53的偏转角度较小的像素光形。提高了像素光形的下边界，使得远光光线更多地照射到距离车辆较远的区域，避免照射在车辆近前方的高亮度光线影响驾驶人对远方照明区域的观察效果，并提高了像素光形的亮度。多个远光光源1的发光状态能够独立进行控制，能够控制远光光形中各像素光形的亮灭，实现自适应远光功能。在本发明的ADB车灯模组的优选实施例中，微透镜2上不同的聚光单元的曲面面积的设置使得远光光源的不同部分具有不同的像素分辨率，提高了ADB的效果。微透镜2上下侧面倾斜设置的方案提高了像素光形的亮度。透镜光轴41偏离远光光源1的发光中心以及远光光源1、微透镜2和半柱面透镜3整体旋转的结构使得所形成的像素光形整体向上抬高，进一步优化了远光照明光形的位置，提高了远光照明效果。点亮光源11和点亮光学元件6的设置提高了近光照明模式下ADB车灯模组的外观效果。相比于如图2所示的传统的ADB车灯模组形成的像素光形，本发明优选实施例中的远光光源1所形成的像素光形如图22所示，像素光形上边界52相对于H轴51的偏转角在4°到10°之间，像素光形下边界53相对于H轴51的偏转角在1°到2°之间。光形的上部照射范围更远，下部的照射边界更高，光线照射更加集中；像素光形中间光形中心区域54的最高照度由54.5lx提高到81.2lx，光形中心区域的亮度更高。因此，本发明的ADB车灯模组所形成的远光照明光形的光分布更加合理，远光照明效果更好。
本发明所提供的车灯，采用了本发明任一实施例的ADB车灯模组；本发明的车辆，使用了本发明的车灯，也具有上述优点。
在本发明的描述中，参考术语“一个实施例”、“一些实施例”、“一种具体实施方式”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本发明中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
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。
