Description

车灯模组及车灯 技术领域
本发明涉及车辆照明装置，具体地涉及一种车灯模组。此外，本发明还涉及一种车灯。
背景技术
汽车大灯包括远光灯和近光灯，近光灯的照明有效距离应在50米，远光灯的照明有效距离应在150米，两者切换使用来照亮车辆前方道路。远光角度高距离远，可以提高视线，扩大观察视野；近光角度低距离近，不会给对方司机造成炫目。在会车时，如果我们使用远光灯，对方驾驶员将由于强光而无法看清路面并无法判断车辆的准确位置，这将增加意外发生的几率。
现有技术中，近光光型可以通过传统的遮光板来形成。光源发出的发散光经反光杯反射后汇聚于反光杯的近焦点附近，经过遮光板遮挡形成明暗截止线，并通过准直透镜成像到路面，通过驱动机构将遮光板移开以形成远光光型。为了精简结构，出现了许多无需移动遮光板即可切换远近光型的车灯结构。申请日2016年8月31日、申请号201610773448.6的中国发明专利公开了一种全新LED远近光一体前照灯投影灯芯，所述LED远近光一体前照灯投影灯芯需要发出近光光线时，打开LED光源的上光源即可发出近光光线，同时打开LED光源的上光源和下光源即可发出远光光线。但此种结构中遮光板不切换，远光由近光光线和远光光线叠加合成，由于合成远光的远光光线明显有更高的亮度，故合成的远光中能看到明显的亮度梯度，对驾驶人员具有一定的干扰性。
针对上述方案中远光亮度不均的问题，申请日为2013年3月13日、 申请号为201310080226.2的发明专利公开了一种机动车的照明装置的光模块，通过改变准直透镜的局部入射面的折射方向，使部分远光光线照射到近光明暗截止线下方，但这种准透镜的特殊结构同时导致近光可利用的透镜入射面面积减少，不符合透镜小型化的要求和趋势，另外，上述方法不但加大了透镜设计、制造及检测的难度，同时要避免近光光线照射到非准直的入射面而导致照射到明暗截止线上方，也导致车灯单元稳定性下降。
随着用户需求的提升，车灯模组除了需要摆脱复杂的遮光板驱动机构，克服还需要进一步提供亮度更加均匀的远近光。
发明内容
本发明第一方面所要解决的技术问题是提供一种车灯模组，该车灯模组能够淡化远光的配光图案的明暗截止线边界，提供亮度更加均匀的远光。
本发明第二方面所要解决的技术问题是提供一种车灯，该车灯能够淡化远光的配光图案的明暗截止线边界，提供亮度更加均匀的远光。
为了实现上述目的，本发明第一方面提供一种车灯模组，包括透镜、一端具有截止线结构的遮光板、近光模块和远光模块，所述近光模块发出的光线适于经所述遮光板截取后射向所述透镜以形成近光光型，所述远光模块发出的光线适于经所述遮光板截取后射向所述透镜以形成位于明暗截止线上方的主远光光型，还包括辅助远光模块，所述辅助远光模块发出的光线适于经所述遮光板截取后射向所述透镜以形成位于明暗截止线下方的辅助远光光型。
优选地，所述近光光型、主远光光型和辅助远光光型均为具有明暗截止线的配光图案，所述远光模块、近光模块和辅助远光模块分别产生的所述近光光型、主远光光型和辅助远光光型能够合成为远光光型。
优选地，所述近光模块包括近光聚光元件和光源，所述远光模块包括远光聚光元件和光源，所述辅助远光模块包括辅助远光聚光元件和光源。

具体实施方式
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，并不用于限制本发明。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“连接”、“设置”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。
首先需要说明的是，在本发明下述技术方案的描述中，以车灯模组自身作为方位基准进行方位术语定义，其中，沿光路出射方向方向，透镜4 所在一端为前，与之相对的一端为后，该“上”、“下”是指车灯模组自身具有的上、下方位，但是，在实际安装情况中，由于车灯模组在车辆内设置位置不同，存在各种可能的方位布置，应当根据实际安装状态并结合本处车灯模组本身为基准对方位术语进行解释，对于车灯模组本身方位的限定，并不构成对本发明的保护范围的限制。
参考图1至图8，本发明基本实施方式的车灯模组，包括透镜4、一端具有截止线结构31的遮光板3、近光模块和远光模块，其中，近光模块发出的光线经所述遮光板3的截止线结构31截取后射向透镜4以形成如图10所示的近光光型，远光模块发出的光线经所述遮光板3的截止线结构31截取后射向透镜4以形成位于明暗截止线上方的如图11所示的主远光光型，该车灯模组还包括辅助远光模块，辅助远光模块发出的光线经遮光板3的截止线结构31截取后射向透镜4以形成位于明暗截止线下方的如图12所示的辅助远光光型。
现有的车灯模组也能够进行远光、近光的切换，但是形成的远光光型具有明显的缺陷，明暗截止线上方的远光亮度高于明暗截止线下方的亮度，明暗截止线以下部分形成远光分布的暗区，远光光型产生明暗截止线形状的亮度梯度，不但影响了远光的路面照明效果，而且存在一定的安全隐患；再有车灯模组对上述现有技术进行了一定的改进，通过使部分远光或者近光光线折射或反射，将这部分光线引导至明暗截止线下方以对远光的暗区进行补光，但此种方法调光较为困难，而且加大了车灯模组中部分光学元件的制造难度。
本发明的车灯模组具有近光模块、远光模块和辅助远光模块，激活近光模块，近光模块发出的近光光线射向遮光板3，部分近光光线被遮光板3遮蔽，部分近光光线从遮光板3的截止线结构31处射出，经透镜4折射后形成位于明暗截止线下方的近光光型；激活远光模块，远光模块发出的远光光线经遮光板3反射，再经透镜4折射后形成位于明暗截止线上方的主 远光光型，该主远光的亮度高于近光的亮度；激活辅助远光模块，辅助远光模块发出的光线射向遮光板3，部分光线被遮光板3遮蔽，部分光线从遮光板3的截止线结构31处射出，经透镜4折射后形成位于明暗截止线下方的辅助远光光型，该辅助远光光型可以对远光分布中的暗区补光，提高远光的亮度和远光亮度的均匀性。
参考图10至图14，近光光型、主远光光型和辅助远光光型均为具有明暗截止线的配光图案，辅助远光的配光图案与常规远光的配光图案中暗区的形状相匹配，辅助远光光型与该近光光型、主远光光型能够合成为亮度均匀的远光。
具体地，近光模块包括近光聚光元件11和光源，远光模块包括远光聚光元件21和光源，辅助远光模块包括辅助远光聚光元件23和光源，其中，光源可以采用LED发光芯片、OLED发光芯片或基于激光光源的发光芯片；近光聚光元件11、远光聚光元件21、辅助远光聚光元件23可以采用椭球型或抛物面反光杯，或者，采用聚光器同样可以起到汇聚光线的作用。
优选地，近光聚光元件11、远光聚光元件21和辅助远光聚光元件23将光源发出的大部分光线汇聚于遮光板3的截止线结构31上或截止线结构31附近，遮光板3的截止线结构31位于所述透镜4的焦点上或位于焦点附近，如此定位可以提高光线率用率并且形成更加清晰的配光图案。
进一步地，近光聚光元件11、远光聚光元件21和辅助远光聚光元件23均设置为反光杯，分别对应称为近光反光杯、远光反光杯和辅助反光杯，上述反光杯可以使用椭球型反光杯或抛物面反光杯。该近光反光杯、远光反光杯和辅助反光杯各自的近焦点处分别对应设有近光光源12、远光光源22和辅助远光光源24，上述反光杯各自的远焦点均落入所述遮光板3的截止线结构31上，需要理解的是，反光杯具有两个焦点，近焦点为光线入射点，远焦点为光线出射点。如此布置近光反光杯、远光反光杯、辅助反光杯、遮光板3和透镜4的相对位置，能够提升光线率用率，并且形成的光 型更加清晰。
作为一种具体地结构形式，参考图1至图3，近光反光杯与辅助反光杯装配连接或一体成型以形成双曲面反光杯，远光反光杯的反射面与该双曲面反光杯的反射面相向设置。需要注意的是，远光反光杯的反射面与该双曲面反光杯的反射面相向设置并不局限于上述两个反射面完全相对立的放置，只要该双曲面反光杯反射的光线可以射向遮光板3的上表面，远光反光杯反射的光线可以射向遮光板3的下表面，上述双曲面反光杯的反射面和远光反光杯的反射面即可以认为呈相向设置的状态。在此种结构下，将近光反光杯和辅助反光杯集成为双曲面反光杯，减少了车灯模组的光学元件的数量；该双曲面反光杯可以一体成型，加快生产效率、降低生产成本、减小调光难度。
作为另一种具体地结构形式，参考图4至图6，近光反光杯的反射面分别与远光反光杯的反射面、辅助反光杯的反射面相向设置。在此种结构形式下，可以减小该车灯模组的径向尺寸。
作为又一种具体地结构形式，参考图7至图9，近光聚光元件11为近光反光杯，远光聚光元件21、辅助远光聚光元件23和遮光板3集成为远光一体聚光器5，如此，可以减小车灯模组的尺寸和车灯模组中光学元件的数量；并且远光一体聚光器5可以一体成型，从而提高生产效率、降低生产成本；将上述多个光学元件集成为一个光学元件，无需调整远光聚光元件21、辅助远光聚光元件23和遮光板3在车灯模组中的相对位置，进一步降低车灯模组的装配难度和调光难度。
具体地，远光一体聚光器5为透明实心光导体，该远光一体聚光器5依次设有或一体成型有入光部52、通光部和出光部。其中，入光部52具有凹槽和向后凸出的入光面，将总远光光源51放置在该凹槽中，这种结构能够使得总远光光源51发出的光线被很好的收集，有利于提高光源利用率；通光部上表面形成有上部全反射面53，通光部下表面形成有向外凸出的下 部全反射面54，光线经上部全反射面53和下部全反射面54反射后能够向远光一体聚光器5的截止线结构57的区域汇聚；出光部形成有第一出光部55和第二出光部56，用于形成辅助远光的光线从第一出光部55射出，用于形成主远光的光线从第二出光部56射出；上部全反射面53与第二出光部56相交形成截止线结构57。调节近光反光杯相对于远光一体聚光器5的相对位置，使得近光反光杯的远焦点位于该远光一体聚光器5的截止线结构57上或该截止线结构57的附近区域，该近光反光杯汇聚的光线射向该截止线结构57，经截止线结构57截取后经透镜4折射形成近光光型，由第一出光部55和第二出光部56射出的光线经截止线结构57截取后经透镜4折射分别形成辅助远光光型和主远光光型。
优选地，远光一体聚光器5的截止线结构57处于透镜4的焦点处，如此设置以形成更加清晰的光型，当然，该截止线结构57也可以位于透镜4的焦点附近。
参考图1至图3，本发明一种优选实施方式的车灯模组，该车灯模组包括三个椭球型反光杯，分别为近光反光杯、远光反光杯和辅助远光反光杯，该近光反光杯、远光反光杯和辅助远光反光杯的近焦点处分别设有近光光源12、远光光源22和辅助远光光源24，该近光反光杯、远光反光杯和辅助远光反光杯的远焦点均落入遮光板3的截止线结构31区域，透镜4焦点位于遮光板3截止线结构31附近，其中近光反光杯和辅助远光杯可以一体成型形成双曲面反光杯。此种结构中，激活近光光源12，近光光源12发出的近光光线射向遮光板3，小部分光线被遮光板3的上反射面反射，大部分光线从遮光板3的截止线结构31处射出，经透镜4折射后形成位于明暗截止线下方的近光光型；激活远光光源22，远光光源22发出的远光光线被遮光板3的下反射面反射至透镜4，再经透镜4折射后形成位于明暗截止线上方的主远光光型，该主远光的亮度高于近光的亮度；激活辅助远光光源24，辅助远光光源24发出的光线射向遮光板3，部分光线被遮光板3的上反射 面反射，部分光线从遮光板3的截止线结构31处射出，经透镜4折射后形成位于明暗截止线下方的辅助远光光型24。明暗截止线下方的辅助远光与近光叠加，与明暗截止线上方的主远光合成远光，参考图10至图14，如此，本发明提供的车灯模组通过运用辅助远光对明暗截止线以下远光的暗区补光，以提供亮度更高、亮度更加均匀的远光，并且可以通过调节近光光源12、远光光源22或辅助远光光源24的亮度，使得叠加形成的远光亮度更加均匀且调光方法简单。
参考图7至图9，本发明又一种优选实施方式的车灯模组，包括近光反光杯和远光一体聚光器5，该近光反光杯近焦点处设有近光光源12，远焦点落入远光一体聚光器5的截止线结构57上或者落入该截止线结构57附近；远光一体聚光器5入光部52的凹槽内设有总远光光源51，截止线结构57与透镜4焦点重合或者位于透镜4焦点的附近。开启近光时，激活近光光源12，该近光反光杯汇聚的光线射向该截止线结构57，部分光线射向远光一体聚光器5的通光部的上部全反射面53后被向下折射，部分光线直接射向透镜4形成近光光型；激活总远光光源51，总远光光源51发出的光线经通光部的上部全反射面53和下部全反射面54反射后，从第一出光部55和第二出光部56射出，汇聚于远光一体聚光器5的截止线结构57附近，从第一出光部55出射的光线形成明暗截止线以下的辅助远光光型，第二出光部56出射的光线形成明暗截止线以上的主远光光型，同时激活近光光源12和总远光光源51即可叠加形成亮度均匀的远光。此种结构进一步减少了车灯模组中的光学元件的数量，缩小了车灯模组的体积，用远光一体聚光器5取代了远光聚光元件21、辅助远光聚光元件24和遮光板3，降低车灯模组的调光难度，加快了其装配速度。
本发明的车灯，包括上述技术方案中所述的光学模组，采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果。
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。
