具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
需要说明的是，在本发明实施例的描述中，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
请参照图1、图2和图3，本实施例提供一种光学模组111，包括第一光源1111以及沿光路传输方向依次设置的初级光学元件1112和出光透镜112，初级光学元件1112为透明件，初级光学元件1112包括入光面1112a、全反射面1112c和第一出光面1112d，截止线结构设置于全反射面1112c靠近入光面1112a的边界处，第一光源1111出射的光线由初级光学元件1112的入光面1112a入射，经全反射面1112c反射后由第一出光面1112d出射并经出光透镜112后在目标平面上投射形成具有明暗截止线的近光光型。需要说明的是，目标平面可以是设置车辆前方25米处的竖直平面。
具体的，第一光源1111发出的光线，由初级光学元件1112的入光面1112a入射，经截止线结构截取并由全反射面1112c反射后经第一出光面1112d出射，通过将初级光学元件1112加工成具有全反射面1112c、入光面1112a和第一出光面1112d的透明件，全反射面1112c靠近入光面1112a边界处作为截止线结构，以使光线由入光面1112a入射初级光学元件1112，并经截止线结构截取后，再由全反射面1112c反射后由第一出光面1112d出 射，最后经出光透镜112后在目标平面上投射形成具有明暗截止线的近光光型。其中，全反射面1112c可以使入射的光线发生全反射现象，减少光线的损失。全反射现象是指当光线射到两种介质界面，只产生反射而不产生折射的现象；当光由光密介质射向光疏介质时，折射角将大于入射角，当入射角增大到某一数值时，折射角将达到90°，这时在光疏介质中将不出现折射光线，只要入射角大于或等于上述数值时，均不再存在折射现象。本申请利用全反射现象，以使传输到全反射面1112c的光线发生全反射后再经第一出光面1112d出射，减少光线的损失。
本申请提供的光学模组111，包括第一光源1111以及沿光路传输方向依次设置的初级光学元件1112和出光透镜112，初级光学元件1112为透明件，初级光学元件1112包括入光面1112a、全反射面1112c和第一出光面1112d，截止线结构设置于全反射面1112c靠近入光面1112a的边界处，第一光源1111出射的光线由初级光学元件1112的入光面1112a入射，经截止线结构截取并经全反射面1112c反射后由第一出光面1112d出射，再经出光透镜112后在目标平面上投射形成具有明暗截止线的近光光型。本申请提供的光学模组111采用透明件作为初级光学元件1112，利用全反射面1112c边界形成截止线结构，简化了光学模组111的结构，省去需要镀膜的反射镜节约了生产成本。
在本申请的一种可行实施例中，如图1所示，全反射面1112c为抛物面型反射面或类抛物面型反射面。
具体的，将全反射面1112c设置为抛物面型反射面或类抛物面型反射面，以使全反射面1112c能够汇聚光源发出的发散光，并且从全反射面1112c反射出的光线为平行光或近似平行光，以能够减小与初级光学元件1112对应的出光透镜112的入光面尺寸，不需要很大的出光透镜112即可保证由初级光学元件1112出射的光线可以尽可能多地经出光透镜112入射面入射出光透镜112，减少光线的损失，保证了光效。
应当指出的是，在本申请的上下文中，当使用术语“类抛物面”时，应当理解为面型接近抛物面的面型，并且具有与抛物面相似的光学特征。例如，类似于抛物面型反射面，在将类抛物面作为反射面时，从位于该类抛物面的焦点或焦点附近的光源发出光线在经该类抛物面的反射后能够以大致平行的方式射出。
在本申请的一种可行实施例中，如图4-图7所示，光学模组111还包括第二光源1113，初级光学元件1112还包括用于接收第二光源1113发出的光线的导向面1112e，第二光源1113出射的光线经过导向面1112e入射初级光学元件1112，由初级光学元件1112的第一出光面1112d出射再经出光透镜112后出射。其中，导向面1112e一端通过衔接面1112b与全反射面1112c连接，导向面1112e另一端与入光面1112a连接。
其中，第一光源1111和第二光源1113均可设置为LED光源，LED光源已经逐渐成为汽 车车灯100的主要配置。且LED光源作为冷光源，其温度较低，减少了第一光源1111和第二光源1113光线输送过程中的能量损耗，延长了第一光源1111和第二光源1113的使用寿命。根据不同的应用场景，第一光源1111和第二光源1113的颜色可以根据不同的需要进行设置，例如第一光源1111和第二光源1113可以为白光源、黄光源，也可以是可以变换颜色的彩色光源。
此外，第二光源1113可以应用于远光照明场景中，作为远光光源使用，也可以应用于车辆信号灯中，作为信号灯光源使用，光学模组111可以实现前照灯与信号灯的复用。
在本申请的一种可行实施例中，如图4和图5所示，导向面1112e位于第一出光面1112d远离出光透镜112的一侧，第二光源1113对应导向面1112e设置，第二光源1113出射的光线经导向面1112e入射初级光学元件1112内，并传输至第一出光面1112d出射。
导向面1112e可以设置为弧面，具有对光线汇聚的作用，将第二光源1113出射的发散光进行汇聚，以保证光线更多地进入初级光学元件1112并到达第一出光面1112d，减少了光线损失，保证了光效。此外，光线被汇聚后不需要大尺寸的第一出光面1112d及对应的出光透镜112，即可使光线由第一出光面1112d出射后尽可能多地入射出光透镜112。
在本申请的一种可行实施例中，如图6和图7所示，导向面1112e包括辅助入光面1112e1和辅助反射面1112e2，辅助入光面1112e1与入光面1112a位于同一侧，辅助反射面1112e2设置于第一出光面1112d远离出光透镜112的一侧，辅助入光面1112e1与辅助反射面1112e2之间具有夹角，以使光线经辅助入光面1112e1后可到达辅助反射面1112e2发生反射，第二光源1113出射的光线经辅助入光面1112e1入射初级光学元件1112内，经辅助反射面1112e2反射后由第一出光面1112d出射。
具体的，第二光源1113出射的光线经辅助入光面1112e1入射初级光学元件1112内，辅助反射面1112e2设置为全反射面，利用全反射现象，射至辅助反射面1112e2的光线会发生全反射后传输至第一出光面1112d出射，减少光线的损失。
进一步地，辅助反射面1112e2的一端与辅助入光面1112e1连接，辅助反射面1112e2的另一端与衔接面1112b远离全反射面1112c的一端连接，辅助入光面1112e1与入光面1112a连接且位于同一平面。
当第二光源1113发光时且应用与远光照明时，投射到目标平面上的远光光型如图9所示，当第一光源1111和第二光源1113同时发光，投射到目标平面上的远近光叠加光型如图10所示。
在本申请的一种可行实施例中，如图7所示，辅助反射面1112e2为抛物面型反射面或类抛物面型反射面。
具体的，第二光源1113出射的光线经辅助入光面1112e1入射初级光学元件1112内， 经辅助反射面1112e2反射后经第一出光面1112d出射，辅助反射面1112e2为抛物面型反射面或类抛物面型反射面，抛物面型反射面或类抛物面型反射面将第二光源1113发出的发散光汇聚成平行光或近似平行光，以保证出射的光线的汇聚程度，提高光线经出光透镜112后在目标平面上形成的远光光型的光能量，此外，光线被汇聚后不需要大尺寸的第一出光面1112d及对应的出光透镜112，即可使光线尽可能多地入射出光透镜112，保证了光效。
进一步的，将辅助反射面1112e2纵向截面的曲率设置为与全反射面1112c纵向截面的曲率一致，当第一光源1111和第二光源1113同时发光时，从全反射面1112c与辅助反射面1112e2反射的光线不会相互干涉，且远近光叠加光型在光型衔接处衔接自然(如图10所示)。
在本申请的一种可行实施例中，如图4和图5所示，第一出光面1112d为柱面。
具体的，将第一出光面1112d设置为柱面，以对经第一出光面1112d的光线进行单方向的准直，使光线汇聚，保证光能量的同时减小出光透镜112的尺寸。进一步地，第一出光面1112d对光线具有水平单方向的准直，第一出光面1112d为由其水平方向上的截线沿其竖直方向上的截线拉伸形成的曲面。
在本申请的一种可行实施例中，出光透镜112具有第二出光面112a，第二出光面112a为柱面。
具体的，将第二出光面112a设置为柱面，以对经第二出光面112a的光线进行单方向的准直，使光线汇聚保证光型的光能量。进一步地，第二出光面112a对光线具有竖直单方向的准直，第二出光面112a为由其竖直方向上的截线沿其水平方向上的截线拉伸形成的曲面。
当出光透镜112的第二出光面112a为柱面，初级光学元件1112的第一出光面1112d也为柱面，且二者皆对光线进行单方向的准直，第二出光面112a的横截线与第一出光面1112d的纵截线相互垂直。光源1111发出的光线经初级光学元件1112的第一出光面1112d被汇聚，且将光线在一个方向上进行准直；当光线进入出光透镜112，并从出光透镜112的第二出光面112a出射时，光线再次被汇聚，第二出光面112a将光线在另一方向上行准直。此时光线经出光透镜112投射得到的光型，由于光线更加集中，光能量更高。
请参照图1-图7，本实施例提供一种光学系统110，包括至少一个前述实施例中的光学模组111。
在本申请的一种可行实施例中，初级光学元件1112包括多个，多个初级光学元件1112沿横向排列并一体成型，出光透镜112包括多个，多个出光透镜112沿横向排列并一体成型，每个初级光学元件1112的第一出光面1112d对光线单方向准直，第一出光面1112纵向截线与出光透镜112的第二出光面112a横向截线相垂直。先通过初级光学元件1112的 第一出光面1112d在水平方向上汇聚光线，再通过出光透镜112的第二出光面112a在竖直方向上汇聚光线，并将多个初级光学元件1112沿横向排列，使得最终光线投射在目标平面上得到所需的叠加光型。
在本申请的一种可行实施例中，如图4-图7所示，光学系统110还包括线路板113，光学模组111的第一光源1111和第二光源1113设置于线路板113上。
具体的，线路板113与第一光源1111和第二光源1113电连接，以使与线路板113连接的操作装置能够分别控制第一光源1111和第二光源1113的开启与关闭，使得光学系统110的控制更加便利，可将第一光源1111和第二光源1113一同开启，也可将第一光源1111和第二光源1113分别开启，以适应不同的照明需求。进一步地，如图7所示，第一光源1111和第二光源1113可以设置于同一线路板113的同一侧，减少了线路板的使用，降低了成本。
请参照图4和图6，本实施例提供一种车灯100，包括前述实施例中的光学系统110，还包括连接在光学系统110上的散热器120。
具体的，散热器120包括散热板以及设置在散热板上的多个散热片，通过多个散热片以增大散热器120的整体的散热面积，从而使得散热器120能够快速吸收第一光源1111和第二光源1113发出的热量，第一光源1111和第二光源1113发出的热量先传递至散热板上，随后再传递至散热片上，以避免第一光源1111和第二光源1113发热而影响其工作效率，进而保证第一光源1111和第二光源1113能够长期稳定的工作。
以上所述仅为本申请的部分实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
