相关申请的交叉引用
本申请要求2020年06月29日提交的中国专利申请202010609464.8的权益，该申请的内容通过引用被合并于本文。
技术领域
本发明涉及车灯，具体地，涉及一种车灯光学系统。此外，还涉及一种车灯模组和车辆。
背景技术
车灯光学系统作为车灯照明的核心部件，开发难度相对较高，开发周期长，所以一般要求标准化，具有较好的通用性，以适应不同的车灯造型及车灯空间。而现有的车灯光学系统一般为整体式，即光源以及光学相关零件之间的位置关系都是固定的，部分具有AFS功能的照明系统虽然可以绕竖直旋转轴进行一定角度的旋转，但其还是在整体式模组的基础上的一种运动过程，其初始位置还是唯一的，并且在旋转过程中需要占用更大的空间。
图1所示为现有的一种整体式的车灯模组，其包括光源、反射镜a和透镜b，在反射镜a的反射光路上设置有用于形成近光截止线的遮光部c，各部件均与散热器直接或间接地固定连接。在此车灯模组中，光源设置在反射镜a的第一焦点处，遮光部c设置在反射镜a的第二焦点处，透镜焦点设置在反射镜a的第二焦点处，因此，整个车灯光学系统中的光学元件的相对位置是唯一确定的，只适用于一种车灯灯内空间的布置。
随着车辆及车灯技术的发展，车灯造型的多变受到灯内空间的限制，但是由于整体式的光学系统光学元件之间的相对位置关系唯一确定，若根据灯内空间重新改变光学元件之间的相对位置则不会得到所需要的光形。因此，整体式的光学系统通用性较低，不利于造型布置和/或无法满足空间布局，往往需要牺牲车灯造型需求来满足结构需求。
另外，由于前照灯、雾灯等功能在装车后有照射角度要求，所以都需要进行调光，现有车灯一般都采用车灯系统整体调节，使得调节空间需求大，光学系统 质量较大，所需支撑强度和调节系统也要求较高，并且存在振动后照明方向偏移的风险。

本发明首先所要解决的技术问题是提供一种车灯光学系统，该车灯光学系统中各元件的空间布局灵活性高，能够满足不同车灯造型及适应不同的灯内空间。

更优选地，所述准直光学元件为具有抛物面形或类抛物面形反射面的反射镜。
本发明第二方面提供一种车灯模组，包括上述所述的车灯光学系统和与所述聚光元件对应设置的光源。

以下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。
在本发明的描述中，需要解释的是，“上”、“下”、“前”、“后”、“左”、“右”等指示的方位关系仅是为了便于描述本发明和简化描述，基于车灯光学系统，“前”是指出光方向所指的方向，“后”是指与“后”相反的方向，“左”是指沿出光方向的左侧，“右”是指沿出光方向的右侧，即与车辆正常行驶的左右侧方向相同，“上”是指沿出光方向的上方，“下”是指沿出光方向的下方，本发明中聚光元件1的出光光路指的是光线经聚光元件1汇聚后主要传输方向的光路，准直光学元件2的出光光路指的是光线经准直光学元件2收集、准直后主要传输方向的光路，第一平面镜31和第二平面镜33的出光光路指的是光线经该平面镜反射后主要传输方向的光路。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。
本发明的描述中，需要说明的是，车灯光学系统中元件“安装位置”的变化包括该元件的平移(即该元件的安装角度不变，进行横向、竖向或斜向移动)和/或该元件的转动(即该元件绕某一个轴进行转动)；两个元件之间的“相对位置”的改变包括两个元件之间相对距离的改变和/或两个元件之间相对角度的改变；照明光形的“标准位置”指的是为《GB 25991-2010汽车用LED前照灯》等车灯相关法规规定的该照明光形在配光屏幕上的投射位置。
本发明第一方面提供的一种车灯光学系统，参见图2至图4、图13、图21至图24，包括基本光学子系统和反光系统3，基本光学子系统包括聚光元件1和准直光学元件2，反光系统3包括位于准直光学元件2的出光光路上的第一平面镜31和/或位于聚光元件1的出光光路上的第二平面镜33；其中，聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33中的至少一者能够调节安装位置，以能够改变聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33中至少两者之间的相对位置，从而使得聚光元件1的出射光线经准直光学元件2和反光系统3进行光路转换后投射形成设定的照明光形。
需要说明的是，准直光学元件2的安装位置可以位于聚光元件1的出光光路上，也可以是位于某一个平面镜(例如第二平面镜33)的出光光路上；聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33的安装位置的调节，可以通过分别与驱动机构连接进行驱动调节，也可以通过手动调节；设定的照明光形可以根据车灯光学系统所在的车灯系统进行设置，例如其可以是前照灯近光照明光形、远光照明光形或者其他车灯照明光形。设定的照明光形确定后，在聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33中的至少一者调节安装位置后，配光屏幕上形成的光形(形状)与设定的照明光形形状相同。
通过本发明上述基本技术方案的车灯光学系统，聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33可以是四者分别能够调节安装位置，也可以是其中一者的安装位置固定，其它三者能够调节安装位置，或者是其中两者的安装位置固定，另两者能够调节安装位置，或者是其中三者的安装位置固定，剩余一者能够调节其安装位置，以能够调节聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33中至少两者之间的相对位置，以满足不同车灯灯具造型及适应不同的车灯内部空间，同时准直光学元件2的准直和反光系统3的反射相配合，使得聚光元件1的出射光线进行光路转换后仍然沿原来的出光方向投射并形成设定的照明光形，实现聚光元件1、准直光学元件2与反光系统3的空间结构布置的灵活变化，聚光元件1和/或准直光学元件2的通用性高，可以反复使用在不同车灯灯具上，减少重复开发。
本发明中，设定的照明光形可以是如图29所示的具有明暗截止线的近光照明光形，也可以是如图30所示的具有中心亮度最大值的远光照明光形。基本光学子系统可以设有相应的截止结构或者遮光结构，以能够使得聚光元件1的出射 光线经准直光学元件2和反光系统3进行光路转换后投射形成照明光形，具有所需的截止线等光形边缘形状，其中，截止结构或者遮光结构可以设置在聚光元件1或者准直光学元件2上，也可以是在基本光学子系统内单独设置具有截止结构或者遮光结构的元件。例如，设定的照明光形为近光照明光形，如图2所示，聚光元件1的发光边界1a可以设置成与近光照明光形的明暗截止线相对应的形状，进而使得聚光元件1的出射光线形成具有明暗区分界线的光形，经准直光学元件2和反光系统3进行光路转换后投射，以形成如图29所示的近光照明光形；也可以通过在聚光元件1的出光光路上设置遮光板，同理，形成近光照明光形的明暗截止线。
本发明中，聚光元件1设置为能够将相应的光源发出的光线进行汇聚，使输出光线基本平行的元件，优选地，参见图9至图12、图17至图20和图25至图28，聚光元件1为聚光器、准直透镜或者具有抛物面形或类抛物面形反射面的反射元件。参见图9至图12，聚光元件1为具有抛物面形或类抛物面形反射面的反射元件时，聚光元件1对应的光源(即后文中的光源4)发出的光线经聚光元件1的抛物面形或类抛物面形反射面进行反射后，实现聚光的效果；参见图17至图20，聚光元件1为聚光器，该聚光器为聚光杯结构，其外部轮廓面呈杯状，光源4发出的光线进入该聚光器内，一部分光线直接传输至聚光器的出光端，一部分光线经聚光器的外部轮廓面反射后再传输至聚光器的出光端，以将光线汇聚；参见图25至图28，聚光元件1为准直透镜，其可以为平凸透镜，也可以为双凸透镜，光源4发出的光线进入准直透镜后，经准直透镜折射，实现聚光的效果。
准直光学元件2设置为能够将入射至该准直光学元件2的光线进行收集准直后射出的元件，优选地，准直光学元件2为具有抛物面形或类抛物面形反射面的反射镜。
作为本发明的第一个具体实施例，参见图2和图13，反光系统3包括第一平面镜31，准直光学元件2位于聚光元件1的出光光路上。此时，聚光元件1的出射光线经准直光学元件2准直投射至第一平面镜31，再经第一平面镜31反射后进行投射形成设定的照明光形。
优选地，聚光元件1与准直光学元件2的相对位置固定。此时，基本光学子系统内部聚光元件1与准直光学元件2的结构位置保持不变，基本光学子系统 可以和车灯模组中的散热器等其他零部件固定连接成一个总成，根据车灯内的空间，通过调整第一平面镜31和基本光学子系统的相对位置来得到沿原来的出光方向投射并形成设定的照明光形。
此时，作为第一个具体实施例的一种优选形式，参见图3，基本光学子系统的安装位置固定，第一平面镜31能够平移，以能够使得第一平面镜31的出光方向不变。在实际安装过程中由于车灯灯体内其它零部件的干涉，第一平面镜31所在的位置可能无法安装，可将第一平面镜31沿准直光学元件2的出光方向平移到虚线所在位置，此时，虽然第一平面镜31和基本光学子系统的相对位置发生了变化，但是第一平面镜31的出射光线仍然沿原来的方向平行向前出射，即第一平面镜31的出光方向不变，并投射形成设定的照明光形，不会影响车灯的光形。由此，第一平面镜31的位置可以根据车灯内其它零部件的布局，进行安装位置的调整，使得本发明的车灯光学系统能够适用于各种不同造型、不同空间大小的车灯灯具。需要说明的是，第一平面镜31的平移方向并不局限于沿准直光学元件2的出光方向，也可以是横向、竖向或者其他斜向的平移。
作为第一个具体实施例的另一种优选形式，第一平面镜31能够绕任一水平轴沿第一方向转动，基本光学子系统能够绕任一水平轴沿第二方向转动，第一方向与第二方向相配合以能够使得第一平面镜31的出光方向不变。本发明中，水平轴指的是水平的且沿车辆左右方向延伸的轴，第一平面镜31和基本光学子系统可以绕同一水平轴转动，也可以是分别绕不同的水平轴转动，通过两者的转动配合来实现第一平面镜31的出光方向不变。具体地，参见图4，在实际安装过程中由于车灯灯体内其它零部件(例如饰圈)的干涉，基本光学子系统可能无法定位安装，此时，第一平面镜31绕经过其端点3a的水平轴进行转动，将第一平面镜31绕该水平轴进行顺时针转动至虚线位置，第一平面镜31的出射光线向下偏转，再将基本光学子系统绕某一个水平轴进行逆时针转动，使得出射光线恢复至沿原来的出光方向向前平行出射，同时基本光学子系统也可以避开其它零部件的干涉，通过改变第一平面镜31和基本光学子系统的相对位置，保持第一平面镜31的出光方向不变并投射形成设定的照明光形。
作为本发明的第二个具体实施例，参见图21至图23，反光系统3包括第二平面镜33，准直光学元件2位于第二平面镜33的出光光路上。此时，聚光元件1的出射光线经第二平面镜33反射至准直光学元件2，再经准直光学元件2 准直后进行投射，形成设定的照明光形。
作为第二个具体实施例的一种优选形式，第二平面镜33的安装位置固定，聚光元件1的出射光线在第二平面镜33上的反射区32位于该第二平面镜33上的固定位置，聚光元件1的出射光线与第二平面镜33的反射光线关于该第二平面镜33位于反射区32内的对应反射点处的法线对称，聚光元件1和准直光学元件2能够分别调节安装位置，以能够使得准直光学元件2的出光方向不变。聚光元件1和准直光学元件2分别能够根据车灯内其它零部件的位置和车灯灯具的内部空间大小调节安装位置，两者在调节时相互配合，改变聚光元件1和准直光学元件2各自与第二平面镜33的相对位置，以使得聚光元件1的出射光线能够投射至第二平面镜33的同一位置(即反射区32)，并经第二平面镜33反射到准直光学元件2的同一位置处，从而实现准直光学元件2准直后的光线的出射方向不变。
具体地，参见图22和图23，聚光元件1和准直光学元件2分别能够绕反射区32进行圆周移动，其中，聚光元件1和准直光学元件2中的一者沿顺时针方向移动后，另一者沿逆时针方向移动。可以理解的是，在受到车灯灯具内其他零部件干扰的情况下，也可以将聚光元件1沿该聚光元件1的出光方向移动，准直光学元件2沿第二平面镜33的出光方向移动，以调整两者的安装位置，避开其它零部件。
作为本发明的第三个具体实施例，参见图24，反光系统3包括第一平面镜31和第二平面镜33，准直光学元件2位于第二平面镜33的出光光路上。此时，聚光元件1的出射光线经第二平面镜33反射至准直光学元件2，再经准直光学元件2准直投射至第一平面镜31，最后经第一平面镜31反射后进行投射形成设定的照明光形。
作为第三个具体实施例的第一种优选形式，与第二个具体实施例的优选形式相同，第二平面镜33的安装位置固定，聚光元件1的出射光线在第二平面镜33上的反射区32位于该第二平面镜33上的固定位置，聚光元件1的出射光线与第二平面镜33的反射光线关于该第二平面镜33位于反射区32内的对应反射点处的法线对称，聚光元件1和准直光学元件2能够分别调节安装位置，以能够使得准直光学元件2的出光方向不变。聚光元件1和准直光学元件2分别能够根据车灯内其它零部件的位置和车灯灯具的内部空间大小调节安装位置，两者在调 节时相互配合，以使得聚光元件1的出射光线能够投射至第二平面镜33的同一位置(即反射区32)，并经第二平面镜33反射到准直光学元件2的同一位置处，从而实现准直光学元件2准直后的光线的出射方向不变。
作为第三个具体实施例的第二种优选形式，基本光学子系统和第二平面镜33的安装位置固定，第一平面镜31能够平移，以能够使得第一平面镜31的出光方向不变。第一平面镜31可以沿横向、竖向或者斜向进行平移，从而第一平面镜31的位置可以根据车灯内其它零部件的布局，进行安装位置的调整，使得本发明的车灯光学系统能够适用于各种不同造型、不同空间大小的车灯灯具。
作为第三个具体实施例的第三种优选形式，第一平面镜31能够绕任一水平轴沿第一方向转动，基本光学子系统和第二平面镜33整体能够绕任一水平轴沿第二方向转动，第一方向与第二方向相配合以能够使得第一平面镜31的出光方向不变。基本光学子系统和第二平面镜33的整体与第一平面镜31可以绕同一水平轴转动，也可以是分别绕不同的水平轴转动，通过两者的转动配合来实现第一平面镜31的出光方向不变。在实际安装过程中能够使得第一平面镜31、基本光学子系统和第二平面镜33分别避开车灯灯体内其它零部件(例如饰圈)的干涉。
作为第一个具体实施例和第三个具体实施例的又一种优选形式，第一平面镜31能够绕任一水平轴和/或任一竖直轴转动，以能够使得设定的照明光形投射在标准位置。此时，仅通过调节第一平面镜31的角度，即可将车灯光学系统的出光方向进行调节，使得第一平面镜31的出射光线投射形成的设定的照明光形位于法规规定的标准位置处，该调节方式能够有效减小车灯光学系统的调光空间以及被调节部件的重量，有助于车灯可靠性的提高。
在本发明上述的车灯光学系统的基础上，参见图5至图8、图14至图16，本发明第二方面提供了一种车灯模组，包括上述的车灯光学系统和与聚光元件1对应设置的光源4。需要说明的是，光源4可以为LED光源或者激光光源，优选地，光源4为LED发光芯片。车灯模组也可以设置与车灯光学系统相匹配的安装支架5、散热器等部件。上述的车灯光学系统可与车灯模组内的其他零部件相配合，有效提升车灯模组的空间布局的灵活度和空间利用率。
本发明第三方面提供了一种车辆，包括上述的车灯模组。因此至少具有上述车灯光学系统和车灯模组实施例的技术方案所带来的所有有益效果，在此不再赘述。
由以上描述可以看出，本发明的车灯光学系统通过调节聚光元件1、准直光学元件2、第一平面镜31与第二平面镜33中至少两者之间的相对位置，以能够使得聚光元件1的出射光线经准直光学元件2和反光系统3进行光路转换后投射并形成设定的照明光形，实现聚光元件1、准直光学元件2与反光系统3的空间结构布置的变化，使得车灯光学系统的空间布局更加灵活，有效提升车灯内的空间利用率，以满足不同车灯灯具造型及适应不同的车灯内部空间；聚光元件1和准直光学元件2可以反复使用在不同的车灯灯具(例如前照灯、雾灯)上，减少重复开发。更特别的，相对于现有车灯系统中，需要对车灯模组的整体进行角度调节，才能实现调整出光方向，本发明可以通过仅对第一平面镜31的角度调节，来实现调整车灯光学系统的出光方向使得照明光形位于标准位置上，可以有效减小调光空间以及被调节部件的重量，有助于车灯可靠性的提高，避免了整体固定式车灯系统调光时需要整体调光，对支撑及调节系统提出更高要求的缺陷。
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。
