本发明涉及车灯，具体地，涉及一种照明模组。此外，本发明还涉及一种包括所述照明模组的前照灯和车辆。
背景技术
近几年，车灯照明技术领域提出了像素化照明的技术方案，车灯包括像素化照明单元和非像素化照明单元，像素化照明单元投射形成像素化光形100，非像素化照明单元投射形成非像素化光形200，如图1所示，非像素化光形200一般形成为近光展宽光形，即辅助近光光形，像素化光形100可以通过光源的亮灭，形成符合不同照明模式的照明光形，实现自适应远光或防炫目远光功能，以及近光截止线、向路面投射像素化符号等功能，如图23所示，通过灭掉一部分光源，像素化光形100形成为具有近光截止线的主近光光形，与非像素化光形200叠加后用于近光照明。以像素化光形100的上下边界角度差为8°为例，其中一种技术方案是像素化光形100的上边界满足自适应远光或防炫目远光的照明需求，下边界满足形成近光截止线的需求，例如如图1所示，光形上边界位于+5°，下边界位于-3°时，这种技术方案，虽然能够满足远处的自适应远光或防炫目远光的像素化照明以及形成近光截止线的需求，但如图2所示，因为像素化光形100的位置较高，照射在路面上较远，投射到路面的像素化符号显示效果较差，因为距离较远，驾驶员可视度不够好，以及像素化符号在远处大距离产生的畸变也较大，因此形成的路面像素化符号投射效果较差。另外一种技术方案是像素化光形100的上边界满足形成近光截止线的需求，下边界满足路面符号投射的需求，例如如图3所示，光形上边界位于+2°，下边界位于-6°，这种技术方案，如图4所示，虽然能够形成近光截止线以及获得路面的符号投射的良好效果，但实现不了自适应远光或防炫目远光像素化照明 的功能，因为像素化光形100的位置较低，照射在路面上较近，满足不了远光照明范围的要求。而如果通过将像素化光形100的上下边界角度同时做大的措施，既满足自适应远光或防炫目远光功能实现的要求，又满足路面符号投射效果良好的要求，会使得LED光源的成本、透镜组设计难度和成本大大增加，其空间占用也比较大。因此，为了克服上述问题，通常会根据不同的照明模式，上下调整像素化照明光形100的位置，然而，对于像素化照明单元和非像素化照明单元集成为一体的模组，在由如图1所示的远光照明模式切换成近光照明模式而将像素化光形100下调时，非像素光形200也随像素化光形100一同下调，从而会形成如图6所示的暗区300，进而会影响近光照明效果。

具体实施方式
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，在下文的描述中为清楚地说明本发明的技术方案而涉及的一些方位词，例如“上”、“下”、“前”、“后”等，以像素化照明部1为例，像素化光源11所在的一端为后，像素化出光透镜13所在的一端为前，而相对于像素化照明部1的前后方向，像素化照明部1的上下两侧所代表的方向即为上下方向。术语为基于附图所示的方向或位置关系，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。
在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“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，或者是一体连接；可以是直接连接，也可以是通过中间媒介间接连接，可以是两个元件内部的连通或两个元件的相互作用关系。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。
如图7所示，本发明提供一种照明模组，包括像素化照明部1和至少一个非像素化照明部2，所述像素化照明部1包括像素化光源11、成像透镜组12和像素化出光透镜13，所述非像素化照明部2沿光线传播方向依次包括非像素化光源21、反射单元23和非像素化出光透镜22，所述反射单元23包括沿上下方向设置的第一反射单元231和第二反射单元232，所述非像素化光源21包括第一光源211和第二光源212，所述第一光源211与所述第一反射单元231、所述第二光源212和所述第二反射单元232一一对应设置，所述第一反射单元231适于将所述第一光源211发出的光线反射后经所述非像素化出光透镜22投射形成用于近光照明模式下的非像素化光形200，所述第二反射单元232适于将所述第二光源212发出的光线反射后经所述非像素化出光透镜22投射形成用于远光照明模式下的非像素化光形200，用于近光照明模式下的非像素化光形200的上边界位于用于远光照明模式下的非像素化光形200的上边界的上方；所述像素化出光透镜12与所述非像素化出光透镜22一体成型。
本发明中，像素化照明部1的左右两侧中至少有一侧设置有非像素化照明部2，优选地，像素化照明部1的左右两侧均设有非像素化照明部2。在远光照明模式下，如图1所示，像素化光源11全部点亮形成如图1所示的像素化光形100，第二光源212在远光照明模式下被点亮，光线经第二反射单元232反射后从非像素化出光透镜22投射形成如图22所示的非像素化光形200，像素化光形100和非像素化光形200的相对位置关系如图1所示，该非像素化光形200用于远光照明模式，能够形成远光照明模式下的辅助近光光形，此时像素化光形100的上边界满足自适应远光或防炫目远光的照明需求，下边界满足形成近光截止线的需求。
假设在远光照明模式下，像素化光源11全部点亮形成如图1所示的像素化光形100，关闭第二光源212并开启第一光源211，光线经第一反射单元231反射后从非像素化出光透镜22投射形成如图23示的非像素化光形200，此时该像素化光形200的上边界位于如图22所示的用于远光照明模式的非像素化光形200的上边界的上方，此时像素化光形100和非像素化光形200的相对位置关系如图4所示，该非像素化光形200若同像素化光形100一同下调时，不会出现暗区300，比如一同下调3°，即可得到如图3所示的符合法规要求的照明光形，该照明光形的像素化光形100的上边界满足形成近光截止线的需求，下边界满足路面符号投射的需求，因此，该非像素化光形200用于近光照明模式，与像素化光形100一同下调后能够形成近光照明模式下不具有暗区300的辅助近光光形。
需要说明的是，在由远光照明模式切换为近光照明模式时，如图4所示的像素化光形100和非像素化光形200一同下调，在近光照明模式下，像素化光源11只有部分被点亮，经成像透镜组12和像素化出光透镜13投射形成如图24所示的近光照明光形中具有近光截止线的像素化光形100，第一光源211点亮，第一光源211射出的光线经第一反射单元231反射后从非像素化出光透镜22投射形成如图24所示的非像素化光形200。通过控制第一光源211和第二光源212的亮灭，使得本发明的照明模组在近光照明模式和远光照明模式切换过程中不会出现图6中所示的暗区300。进一步地，第一反射单元231和第二反射单元232的上下位置并不一定局限于第一反射单元231设于第二反射单元232的上方，也可以将第一反射单元231设置在第二反射单元232的下方，通过调整各自的配光角度来实现各自的功能，造型更加灵活多变。
在由远光照明模式切换为近光照明模式的过程中，需要设置调光机构对该照明模组进行调光，作为调光机构的一种实施方式，如图25和图26所示，照明模组上连接有调光机构，该调光机构包括三个球头螺杆组件4，单个球头螺杆组包括球头螺杆41和球头螺母42，其中一个球头螺杆41的 一端通过球头螺母42与散热器6连接，另一端连接有固定在灯体或相对灯体固定不动的支撑件上的调光执行器5，另外两个球头螺杆组件4的球头螺杆41一端通过球头螺母42与散热器6连接，另一端固定在灯体或相对灯体固定不动的支撑件上，两个球头螺杆41的球头球心形成水平的调光轴，当设置在上部的调光执行器5驱动与之连接的球头螺杆41前后移动时，照明模组能够围绕水平的调光轴转动，进而对照明模组进行上下调光，使得照明模组的像素化光形100和非像素化光形200整体上下移动，将如图4所示的照明光形位置调整至如图3所示的照明光形位置，以满足近光截止线和路面符合投射的需求。
进一步地，本发明中，将像素化照明部1与非像素化照明部2设置在同一模组内，针对该模组设置散热装置即可实现对像素化照明部1与非像素化照明部2整体进行散热。作为本发明的一个优选实施方式，所述反射单元23的反射面形成为抛物面，所述反射单元23的反射面的下边界形成为截止线结构，经过反射单元23的反射面的下边界的光线对应形成辅助近光光形的上边界。
更优选地，所述非像素化出光透镜22包括非像素化出光透镜入光面221和非像素化出光透镜出光面222，所述非像素化出光透镜入光面221的横向截线和纵向截线均为向后凸出的曲线，且所述非像素化出光透镜入光面221的横向截线的曲率大于纵向截线的曲率。
由于非像素化出光透镜入光面221的横向截线的曲率大于纵向截线的曲率，非像素化出光透镜入光面221形成为中心区域凸出于四周边沿的后凸曲面，经第一反射单元231和第二反射单元232反射的光线经非像素化出光透镜22出射后，能够形成为左右角度范围大于上下角度范围的展宽光形，满足近光照明的法规要求。
作为本发明的另一个优选实施方式，所述第一反射单元231的数量为两个，两个所述第一反射单元231沿左右方向设置，所述第二反射单元232的数量为一个，且所述第一反射单元231和所述第二反射单元232为反射 镜。设于上方的第一反射单元231在近光照明模式下开启，对应形成近光照明模式下的辅助近光光形，第二反射单元232设于下方，在远光照明模式下开启，对应形成远光照明模式下的辅助近光光形，可以想到的是，第一反射单元231和第二反射单元232两者之间不仅可以调换位置，两者的数量也可以根据实际出光需求而改变。
作为本发明的又一个优选实施方式，如图8至图12所示，所述非像素化出光透镜入光面221包括沿上下方向设置的至少一个第一入光面2211和至少一个第二入光面2212。
从图8至图12中可以看出，非像素化出光透镜入光面221包括第一入光面2211和第二入光面2212，第一入光面2211和第二入光面2212对应于第一反射单元231和第二反射单元232，第一入光面2211和第二入光面2212形成为两个相互独立的后凸曲面，使得本发明的非像素化出光透镜22能够根据实际出光需要而改变第一入光面2211和第二入光面2212的形状、曲率等，使得非像素化出光透镜入光面221的设计更加灵活。
作为本发明的一个具体结构形式，如图15所示，所述非像素化光源21的发光面与水平面间的夹角为5°-30°。优选地，非像素化光源21的发光面与水平面间的夹角为10°-20°，以能够使得非像素化光源21射出的光线尽量多地经反射单元23反射后进入非像素化出光透镜22，提高照明模组的光学效率。
作为本发明的另一个具体结构形式，所述像素化出光透镜13包括像素化出光透镜入光面131和像素化出光透镜出光面132，所述非像素化出光透镜出光面222和所述像素化出光透镜出光面132形成为曲率连续的曲面，从而能够使得像素化出光透镜12和非像素化出光透镜22的整体性较好，造型效果较好。同时，如图16至图21所示，非像素化出光透镜出光面222可以形成为平面或曲面，并且形成为曲面的非像素化出光透镜出光面222的曲率较小，使得形成的曲面较为平坦，有利于提高造型美观度，同时加工简单方便。
进一步具体地，所述成像透镜组12包括由后向前依次排列的第一成像透镜121和第二成像透镜122，所述第一成像透镜121设置为入光面与出光面均呈外凸曲面的双凸透镜，所述第二成像透镜122设置为入光面呈内凹曲面、出光面呈外凸曲面的凸凹透镜。
本发明中，将第一成像透镜121设置为入光面与出光面均呈外凸曲面的具有正折射光焦度的双凸透镜，能够使得第一成像透镜121的焦距更短、屈光度更高，从而能够减小第一成像透镜121与像素化光源11间的距离；将第二成像透镜122设置为入光面呈内凹曲面、出光面呈外凸曲面的具有负折射光焦度的凸凹透镜，能够对光线经过第一成像透镜121折射后产生的色散现象进行抵消和修正，还能够减小其与第一成像透镜121和像素化出光透镜13之间的距离；将像素化出光透镜13设置为入光面与出光面均呈外凸曲面的具有正折射光焦度的双凸透镜，能够减小其与第二成像透镜122之间的距离，从而能够有效减小像素化照明部1的前后长度尺寸，使得照明模组体积小、制造成本低。上述透镜的折射光焦度代表透镜处理光线的能力，正折射光焦度代表透镜能够使进入的光线汇聚，而负折射光焦度代表透镜能够使进入的光线发散。第一成像透镜121、第二成像透镜122和像素化出光透镜13的搭配方式，能够有效的抵消光线折射过程中的色散，使得像素光形的色散范围小，从而使得成像更加清晰，光形效果好。
作为本发明的有一个具体结构形式，所述像素化光源11为多个能够独立控制亮灭的LED发光单元。
本发明中，像素化光源11设置为多个LED发光单元时，可以利用一个或者多个像素化照明部1中部分LED发光单元发光形成像素化光形100的光形作为部分近光光形，如图24所示，利用一个或者多个非像素化照明部2形成非像素化光形200，配合像素化光形100中的部分近光光形以形成完整的车辆前照灯近光照明用的光形。
另外，所述像素化光源11为多个能够独立控制亮灭的LED发光单元。本发明的像素化光源11可以设置为多个能够独立控制亮灭的LED发光单 元，具体可以为矩阵式排布的LED颗粒或者Micro LED，优选为Micro LED光源，即一种微缩LED光源，该微缩LED光源中的各个LED单元的尺寸为微米级别，且该微缩LED光源进一步优选为由上万颗微米级LED单元所组成的矩形阵列式LED光源；选用微缩LED光源能够使得像素点更小更密集，从而能够使得形成的像素图像的清晰度更高，进而能够实现对像素图像投射出去后所形成的光形进行更高精度的调控，形成的暗部的边界以及暗部位置的变化也更加精细流畅，能够更好地避免对行人或驾驶员造成炫目或致盲，而且该微缩LED光源呈矩形阵列，能够获得更宽的光形，以照亮道路两侧的区域，有利于驾驶员对道路两侧的行人以及路标的观察。
在上述照明模组的基础上，本发明第二方面提供了一种前照灯，包括上述任意一项技术方案所述的照明模组。因此至少具有上述照明模组实施例的技术方案所带来的所有有益效果，所形成光形的精度高、稳定性好、远光照明模式切换为近光照明模式时无暗区300，照明光形效果好，且灯体占用的空间小、制造成本低。
进一步地，本发明第三方面的车辆，包括本发明上述第二方面中所述的前照灯，也具有上述照明模组实施例的技术方案所带来的所有有益效果。
由以上描述可以看出，本发明的照明模组将像素化照明部1与非像素化照明部2设置于同一个模组中，不仅能够有效减小照明模组的体积，减小前照灯占用空间，降低生产成本，还能够通过沿上下方向设置的第一反射单元231和第二反射单元232分别用于形成近光照明模式下的非像素化光形200和远光照明模式下的非像素化光形200，用以实现远光照明模式切换为近光照明模式时不会出现暗区300，优化出光效果，使得光形的照明效果好。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，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，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过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。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
