具体实施方式
下面将参照附图借助于示例性实施方式对本公开进行详细描述。要注意的是，本公开的示例性实施方式旨在使得本领域的普通技术人员可以容易地实施本公开，本公开的各实施方式可以以许多不同的形式来实现，而不应当被解释为限于本公开中所阐述的实施方式。相应的，对本公开的以下详细描述仅仅是出于说明目的，而绝不是对本公开的限制。此外，在各个附图中采用相同的附图标记来表示相同的部件。
还需要说明的是，为了清楚起见，在说明书和附图中并未描述和示出实际的特定实施方式的所有特征，并且，为了避免不必要的细节模糊了本公开关注的技术方案，在附图和说明书中仅描述和示出了与本公开的技术方案密切相关的装置结构，而省略了与本公开的技术内容关系不大的且本领域技术人员已知的其他细节。
本公开涉及车灯照明装置，特别是车辆的前照灯。市场上对车辆前照灯的小型透镜车灯模组的需求越来越多，比如要求透镜出光面的上下尺寸或左右尺寸小于等于30mm，尤其是小于等于20mm，一般小型透镜车灯模组以窄长透镜居多(比如窄长造型的车灯)，即上下方向或左右方向中一个方向的尺寸小，另一个方向的尺寸大。在一些小型透镜车灯模组的示例中，透镜的上下尺寸为15mm、左右尺寸为30mm。如果将现有技术中的透镜出光面尺寸较大的车灯模组直接缩小，则不能满足前照灯出射光的光形、光学性能和光学效率等方面的要求。此外，现有的用于远近光一体车灯的光学模块组件可以包括组装在一起的远光模块和近光模块，然而这样的光学模块组件存在光学结构复杂、零部件较多、整体尺寸较大以及成本较高等问题。
针对上述问题，本公开提出一种用于小型近远光一体车灯的光学元件。
以下结合图1至图8对根据本公开的远近光一体车灯光学元件的一示例性实施方式进行说明。图1为根据本公开示例性实施方式的远近光一体车灯光学元件的立体图。图2为根据本公开示例性实施方式的远近光一体车灯光学元件的光路示意图。
在图1和图2所示的实施方式中，车灯模组包括近光光源10、远光光源20和远近光一体车灯光学元件101，远近光一体车灯光学元件101构造成接收由近光光源10和远光光源20发出的光，近光光源10和远光光源20布置在远近光一体车灯光学元件101的同一侧处。
根据本公开的示例性实施方式的远近光一体车灯光学元件101可以包括近光配光部1、远光配光部2和出光部40。近光配光部1可以构造成对由近光光源10发出的光的传播路径、光强分布等进行控制，并且远光配光部2可以构造成对由远光光源20发出的光的传播路径、光强分布等进行控制。由近光光源10和远光光源20发出的光经由远近光一体车灯光学元件101而从远近光一体车灯光学元件101的与布置有近光光源10和远光光源20的一侧相反的另一侧出射。
在一些实施方式中，远近光一体车灯光学元件光学元件101的近光配光部1、远光配光部2和出光部40可以成型为一体件。
在一些实施方式中，远光配光部2可以在竖向方向上设置在近光配光部1的下部。
在一些实施方式中，远光配光部2可以由与近光配光部1的透明材料不同的透明材料制成。
如图2示意性示出的，根据本公开的示例性实施方式的远近光一体车灯光学元件101，从近光光源10和远光光源20发出的光经由远近光一体车灯光学元件101而出射的方向设定为光路方向F，出光部40在光路方向F上设置在近光配光部1和远光配光部2的下游，使得从近光光源10发出的光经由近光配光部1而从出光部40出射以形成近光光形，从远光光源20发出的光经由远光配光部2而从出光部40出射以形成远光光形。
在本公开的上下文中，“光源”可以特别地表示光的来源(例如，发光的装置或设备)。例如，光源可以是当被激活时发光的发光二极管(LED)。在本公开的上下文中，光源基本上可以是任何光源或光发射器，其包括但不限于发光二极管(LED)、激光器、荧光灯、白炽灯等。
在本公开的上下文中，“出光部”可以特别地表示构造成用于对光线进行会聚和投射，以形成符合法规要求的照明光形的光学元件。在一些示例中，出光部40可以为凸透镜结构，该出光部40的出光面可以是向前凸出的球面，也可以是向前凸出的椭球面或者自由曲面等。在一些示例中，出光部40可以由聚碳酸酯材料(PC材料)或者有机玻璃(PMMA)制成。
在本公开的上下文中，使用的方位词如“前、后、上、下、左、右”所指示的方位或位置关系是基于本公开的车灯正常安装在车辆上后的方位或位置关系。其中，方位词“前”所指示的方向为车辆的正常行驶方向。对本公开的车灯光学元件和车灯模组及其零部件的方位或位置关系的描述与其实际使用中的安装方位一致。
在所示出的本公开的示例性实施方式中，远近光一体车灯光学元件101的近光配光部1、远光配光部2和出光部40可以是通过嵌件注塑或者双色注塑的方式一体成型的，也可以是以其他适合的方式一体成型的。因此，根据本公开的远近光一体车灯光学元件结构简单并且便于制造，从而降低了生产成本。
在本公开的一些实施方式中，远光配光部2的材料可以包括硅胶材料。在一些实施方式中，近光配光部1的材料可以包括聚碳酸酯材料(PC材料)、有机玻璃(PMMA)。
需要指出的是，由于PC材料和PMMA的折射率均大于硅胶材料的折射率，在PC材料或者PMMA中传输的光线照射到PC材料与硅胶材料的分界面或者PMMA材料与硅胶材料的分界面时能够产生全反射，在硅胶材料中传输的光线照射到PC材料与硅胶材料的分界面或者PMMA材料与硅胶材料的分界面时则不会产生全反射。
根据所示出的本公开的示例性实施方式的构型，远近光一体车灯光学元件101是一体成型的，因此根据本公开的远近光一体车灯光学元件在满足车辆前照灯的光照要求的同时具有光学结构简单、配光灵活、尺寸较小、集成度较高的优点，因此能够实现远近光一体车灯的小型化的需求，且成本较低。
在一些实施方式中，如图2所示，在近光配光部1的下部可以设置有槽，远光配光部2可以设置在槽中。沿着光路方向F，近光配光部1依次包括近光入光部11和近光导光部12，近光入光部11构造成接收由近光光源10发出的光，近光导光部12构造成对由近光入光部11接收的光进行传递；并且沿着光路方向 F，远光配光部2依次包括远光入光部21和远光导光部22，远光入光部21构造成接收由远光光源20发出的光，远光导光部22构造成对由远光入光部21接收的光进行传递。在一些实施方式中，在近光导光部12的下部可以设置有槽，远光导光部22可以设置在槽中。
在本公开的一些实施方式中，近光入光部11可以包括聚光部，例如该聚光部形成为具有聚光杯形状，该聚光部构造成用于对入射的光进行准直会聚。
在本公开的一些实施方式中，远光入光部21的入光面可以包括平面、外凸曲面或者内凹曲面。
在本公开的一些实施方式中，如图1所示，远近光一体车灯光学元件101还可以包括共用导光部30，该共用导光部30可以在光路方向F上设置于近光导光部12和远光导光部22的下游和出光部40的上游，共用导光部30可以与近光导光部12和远光导光部22连接，并且共用导光部30可以构造成用于接收由近光导光部12和远光导光部22传递的光。
在本公开的一些实施方式中，共用导光部30与近光配光部2成型为一体件。
例如，在一些示例中，近光配光部1的近光导光部12和共用导光部30两者可以由相同的透明材料制成并且可以形成主导光部。在一些实施方式中，近光导光部12、共用导光部30和出光部40可以由相同的透明材料制成，因此减少了近光光线通过时的反射，提高了光效，也便于加工。
在一些实施方式中，主导光部的折射率可以设置成大于远光导光部22的折射率。在一些示例中，近光导光部12和共用导光部30两者可以由聚碳酸酯材料制成，远光导光部22可以由硅胶材料制成。因此，在近光导光部12与远光导光部22之间形成有第一分界面100，并且在远光导光部22与共用导光部30之间形成第二分界面200。
如下参照图2对根据本公开的示例性实施方式的图1所示的远近光一体车灯光学元件的光路原理进行说明。
近光光源10发出的光线经近光入光部11会聚准直后进入近光导光部12，一部分光线依次经过近光导光部12、共用导光部30并从出光部40出射，另一部分光线射至第一分界面100上，在主导光部的折射率设置成大于远光导光部22的折射率的情况下，射至第一分界面100的光线中的大部分光线的入射角会达到全反射临界角，从而发生全反射，反射至出光部40并射出。光线经出光部40投射后形成近光光形。
另外，远光光源20发出的光线经远光入光部21入射至远光导光部22，光线直接射至第二分界面200或经第一分界面100反射至第二分界面200，由第二分界面200折射至出光部40，经出光部40投射后形成远光光形。
在主导光部的折射率设置成大于远光导光部22的折射率的情况下，远光光源20发出的光线不会在第一分界面100处发生全反射，将会有少量光线经第一分界面100出射至近光配光部的主导光部，经出光部40出射后投射至近光光形区域，从而有利于远近光光形的衔接，避免远近光衔接处出现暗区，影响驾驶员的视觉效果。
因此，根据本公开的上述示例性实施方式的构型，近光光源和远光光源能够分别进行控制。在近光模 式下，当近光光源单独打开时，所形成的近光光形能够用于车辆的近光照明。在远光模式下，当近光光源和远光光源同时打开时，近光光形与远光光形相互组合，形成用于车辆远光照明的光形。
根据本公开的远近光一体车灯光学元件在远光模式下能够在近光光形与远光光形之间形成远近光重叠区，近光光形与远光光形两者衔接良好，照明效果更好。
在本公开的一些实施方式中，参照图2，近光导光部12设置有截止线结构24，该截止线结构24可以设置在近光导光部12与远光导光部22之间的第一分界面100的前边缘处。照射至截止线结构24上的光经出光部40投射后对应形成近光明暗截止线(例如图18和图19所示的近光光形110的上边界)。
根据本公开的包括远近光一体车灯光学元件的车灯模组进行配光试验时投射到配光屏幕上所形成的近光光形图具有明显的明暗截止线，符合现行的国家标准《汽车用LED前照灯》(GB25991-2010)的相关规定。
在根据本公开的示例性实施方式中，远近光一体车灯光学元件101的近光光源10可以包括沿着水平方向设置的多个近光光源10(例如3个近光光源)，并且近光配光部可以包括沿着水平方向设置的多个近光入光部11(例如3个近光入光部，如图3所示)。在示出的实施方式中，多个近光光源可以设置成以一一对应的方式与多个近光入光部11对准。
在根据本公开的示例性实施方式中，远光光源20可以包括沿着水平方向设置的多个远光光源20(例如3个远光光源)，并且远光配光部可以包括沿着水平方向设置的多个远光入光部21(例如3个远光入光部，如图3所示)。在示出的实施方式中，多个远光光源中20设置成以一一对应的方式与多个远光入光部21对准。
在本公开的上下文中，“纵向方向”可以特别地表示远近光一体车灯光学元件的长度方向(例如图4中所示的Y方向)，“水平方向”可以特别地表示为与纵向方向垂直的方向(例如图4中所示的X方向)。此外，本公开的上下文中的表示数目的表述“多个”可以理解为表示两个或两个以上。
在一些实施方式中，参照图8，远光导光部20包括多个导光柱，例如三个导光柱221、222、223。多个导光柱221、222、223的与多个远光入光部21连接的第一端部是彼此间隔开的，并且多个导光柱221、222、223的与第一端部相反的第二端部被制成为结合在一起，以形成远光融合部23。
在一些实施方式中，多个导光柱221、222、223之间形成有楔形间隙224、225。如图8所示，在三个导光柱221、222、223之间形成有两个楔形间隙224、225，该楔形间隙224、225是空气间隙或者填充有与主导光部的材料相同的透明材料，例如，主导光部可以由聚碳酸酯材料制成，并且该楔形间隙可以填充有聚碳酸酯材料。
根据本公开的上述示例性实施方式的构型，该楔形间隙可以通过填充与主导光部的材料相同的透明材料以保持多个导光柱之间的位置稳定性，各个导光柱对应的出射光线经出光部40投射后，相互叠加形成多个并排且衔接的ADB(Adaptive Driving Beam，自适应远光系统)远光像素，从而形成多组矩阵式光形(例如图18和图19所示的远光光形120)，使得远光ADB光形的控制精度更高。
图9为设置有根据本公开示例性实施方式的远近光一体车灯光学元件101的覆盖件的示意图。在一些示例性实施方式中，远近光一体车灯光学元件101可以设置有覆盖件50。覆盖件50可以设置成围绕远近光一体车灯光学元件101的远光配光部20和近光配光部10两者的外周部。
在一些实施方式中，远近光一体车灯光学元件101与覆盖件50可以成型为一体件。在一些实施方式中，覆盖件50可以由不透光材料形成。在一些示例中，覆盖件可以是由PC黑色材料形成的不透光层。
根据本公开的上述示例性实施方式的构型，作为不透光层的覆盖件50可以防止远近光一体车灯光学元件内的光线从侧面出射，有效避免了从侧面出射的光线投射后形成影响车灯照明的杂散光，从而提高有效光的输出。
在一些实施方式中，参照图9至图12，在覆盖件50的靠近近光光源和远光光源的一侧(后侧)设置有安装部60，覆盖件50与安装部60可以是一体成型的，并且远近光一体车灯光学元件101通过安装部60紧固连接至车灯模组。通过将紧固连接件71(例如安装螺钉、螺栓)与安装部60连接而将远近光一体车灯光学元件组装到车灯模组中。车灯模组还包括用于安装近光光源10和远光光源20的线路板90，该线路板90的一侧设置有散热器80，散热器80能够提高线路板90的散热性能，避免光源的温度过高，提升光源的稳定性。安装部60可以包括定位销70和螺纹孔62、63和64。例如通过将定位销70与线路板90上的定位孔定位并且将紧固连接件71与螺纹孔64接合，使得远近光一体车灯光学元件101与线路板90和散热器80连接。在另外一些实施方式中，安装部60可以通过卡扣连接、粘接、铆接等与线路板90和散热器80连接，从而确保远近光一体车灯光学元件101作为一个整体在灯体内定位准确，固定良好，并且防止窜动。
图13至图17示出了根据本公开的另外的示例性实施方式的远近光一体车灯光学元件。图13所示的本公开的示例性实施方式的远近光一体车灯光学元件与图3所示的本公开的示例性实施方式的远近光一体车灯光学元件基本上相同。以下将参照图13至图17对其中示出的示例性实施方式与图3所示的示例性实施方式的区别进行描述，而对于与图3所示的示例性实施方式相同的部件和特征，将不再赘述。
根据图13所示的远近光一体车灯光学元件的示例性实施方式，近光入光部11和近光导光部12由不同的透明材料制成。在近光入光部11与近光导光部12之间形成有第一配光面13。
在一些示例中，近光入光部11可以由耐热材料制成，比如由硅胶材料制成，并且近光导光部12可以由聚碳酸酯材料制成。由于近光入光部11设置成靠近光源，近光入光部设计成由硅胶材料形成，可以进一步提高了远近光一体车灯光学元件的耐热性。
根据本公开的上述示例性实施方式的构型，形成在近光入光部11与近光导光部12之间的第一配光面13可以设置为平面、外凸曲面或者内凹曲面。第一配光面13能够用于调节近光光形的光形分布，并且因此能够增加本公开的远近光一体车灯光学元件的配光参数，从而能够通过本公开的远近光一体车灯光学元件来实现灵活配光。
图18和图19为根据本公开示例性实施方式的包括远近光一体车灯光学元件的车灯模组所形成的光形示意图。
在一些实施方式中，如图18所示，在远光模式下，当近光光源10和远光光源20同时打开时，近光光形110与远光光形120相互组合，能够形成用于车辆远光照明的没有衔接暗区、远近光光形衔接良好的照明光形。
图19示出了使用根据本公开的远近光一体车灯光学元件来实现无眩目照明功能的应用场景。例如，当道路前方出现其他道路使用者比如车辆A和/或行人B时，车辆的控制器可以配置成关闭部分远光光源，从而使得车辆A和/或行人B所在区域的局部远光光形形成暗区，避免车辆A的驾驶员和/或行人B产生眩目。因此，根据本公开的远近光一体车灯可以通过在远光光形中产生暗区来实现无眩目照明功能。
以上参照附图并通过实施方式的描述对本公开进行了说明，但是本公开并不局限于上述实施方式。本领域技术人员可以理解，在不脱离本公开技术思想的情况下可以进行修改和变型，这些修改和变型同样包含在本公开的保护范围内。

工业实用性
本公开提供了远近光一体车灯光学元件和包括该远近光一体车灯光学元件的车灯模组和车辆。相比于现有技术中的包括组装在一起的近光模块和远光模块的远近光一体车灯，本公开的远近光一体车灯光学元件成型为一体件，能够在满足车辆前照灯的光照要求的同时具有光学结构简单、配光灵活、尺寸较小、集成度较高的优点，因此能够实现远近光一体车灯的小型化的需求，且成本较低。
此外，可以理解的是，本公开的远近光一体车灯光学元件、车灯模组和车辆是可以重现的，并且可以应用在多种工业应用中。例如，本公开的远近光一体车灯光学元件可以应用于较小的窄长造型的车灯中。
