Description
本发明涉及车辆照明***,具体地涉及一种车灯照明装置。本发明还涉及一种车辆前照灯和一种车辆。
车灯的造型越来越多样化,在车辆前照灯方面,出现了一种通过分散设置的多个车灯照明单元以一定的形式排列而构成一个整体前照灯的造型,即车灯照明分散设置为多个车灯照明单元,产生多个照明区域,而由多个车灯照明单元组合成一个前照灯,多个照明区域组合成一个照明光形。这样的车灯造型更加灵动,设计灵活性更高,可以根据不同车辆对车灯造型的要求,将出光部按照一定的排布形式进行设置,比如沿某直线形式进行排布,或者沿弯折线形式进行排布,亦或者沿曲线形式进行排布等等。
但上述前照灯由多个独立的车灯照明单元构成,由于各个车灯照明单元在零件制造和安装上存在公差,该车灯的各个照明单元之间需要比较复杂的调光校准,校准各个车灯照明单元之间的光形位置,形成准确的完整车灯光形。通常每一个车灯照明单元单独设置调光机构用于调光。例如如图1所示的车灯,按车灯造型要求,设置有六个按斜向直线等距离规则排列的车灯照明单元1,照明支架2相对车灯的灯体固定不动,各个车灯照明单元1均设置于该照明支架2上,图1所示的位置是设计状态。但由于零件制造和安装偏差的存在,每个车灯照明单元1的光形相对于设计位置都具有一定的偏差,需要通过调光机构对各个车灯照明单元1在照明支架2上的位置进行上下左右的调整,使得多个车灯照明单元1产生的照明区域组合成符合要求的完整车灯光形。经过调光之后,各个车灯照明单元1的 位置就偏离了设计状态的位置,如图2所示,各个车灯照明单元1不再是沿着斜向直线等距离规则排列,排列比较凌乱且距离不等,导致经调光以后的车灯满足不了车灯的造型设计要求。
另外,现有的车灯照明单元通常由包括散热器、线路板、光源、初级光学元件、次级光学元件以及相关的固定支架构成一个总成,各个总成在调光机构的调节下可以上下左右移动或摆动。因此,各个车灯照明单元之间需要留有一定的距离以满足调光需要,即各车灯照明单元需要相互独立且间隔设置,这就导致整个车灯照明装置的整体尺寸较大,占用空间大。

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“安装”、“设置”或“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。
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,本发明的保护范围并不局限于下述的具体实施方式。
如图3到图5所示,本发明的车灯照明装置的一个实施例,包括第一光学元件3和多个光源组件4。多个光学单元31按照设计造型的要求依次连接形成了第一光学元件3。各光源组件4上均设置有光源41,光源41可以由单个或者多个LED颗粒组成,多个光源组件4一一对应地设置在多个光学单元31的后方,并保持光源41位于相应的光学单元31的正后方所在的范围内。每个光源41所发出的光线射向相应的光学单元31,并经光学单元31投射出去,形成一个照明区域。多个照明区域组合在一起成完整的车灯光形。每个光源组件4的位置能够独立地调节,使得各个光源41相对于各自对应的光学单元31的光轴之间的角度和/或距离能够产生相应地改变,以独立地调节各个光源41发出的光线经过相应的光学单元31投射后所产生的照明区域。光源组件4位置的调节可以通过调节光源组件4的安装位置来实现,也可以通过调节光源组件4的安装角度来实现,具体的实现方式在后文中进一步描述。通过对每个光源组件4的调节,可以调节每个照明区域的位置从而形成准确的完整的车灯光形,也就是车灯的调光。由于该调光过程中不涉及第一光学元件3的调节,因而不影响本发明的车灯照明装置的外形,使得本发明的车灯照明装置能够保持设计造型不变。同时,由于各光学单元31之间的位置不需要调节,能够将各光学单元31设计得较为紧凑,以减小本发明的车灯照明装置的空间占用。
作为本发明的一个实施例,如图7至12所示,本发明的车灯照明装置中还设置有第二光学元件6。第二光学元件6可以使用透明材料制成的多种导光器件,如光导纤维、有机高分子透明材料或玻璃制成的柱状或条索状导光器件。第二光学元件6分别与光源组件4和光学单元31一一对应地设置,各光源41发出的光线通过第二光学元件6投射到相应的光学单元31上。第二光学元件6能够将射入的光线限制在其本身的范围内进行投射, 能够将光源41发出的光线更多地投射到对应的光学单元31上。
在本发明的一些实施例中,如图8、图10和图12所示,第二光学元件6包括入光口61和出光面62。第二光学元件6设置在光源组件4与第一光学元件3之间。入光口61邻近相应的光源41,以更多地收集光源41所发出的光线;出光面62朝向相应光学单元31,以将光线更好的向光学单元31进行投射。
在本发明的一些实施例中,如图8到图12所示,本发明的车灯照明装置中还设置有支架7,支架7安装在光源组件4上,第二光学元件6安装在支架7上,并保持第二光学元件6稳定地位于光源组件4与第一光学元件3之间。
在本发明的一些实施例中,第二光学元件6采用聚光器。聚光器采用透明高分子材料注塑而成,市场上具有多种结构形式的成品出售,也可以根据所需要的形状进行定制,价格低廉,获取方便。
在本发明的一些实施例中,如图5到图12所示,本发明的车灯照明装置中还包括散热器5,与现有技术中的每个车灯照明单元独立且间隔地设置多个散热器件不同,本发明的车灯照明装置设置仅一个整体的散热器5,多个光源组件4均独立地安装在散热器5上,并且可以独立地调节光源组件4在散热器5上的安装位置。在该实施例中,由于只有光源组件4和安装在光源组件4上的第二光学元件6、支架7需要调节位置,而散热器不需要调节位置,散热器采用了一个整体的结构,从而在减小了散热器空间占用的基础上增加了散热器的材料体积,提高了散热器的散热效果。
在本发明的一些实施例中,如图3、图5所示,第一光学元件3也安装在散热器5上。整体形式的第一光学元件3直接安装在整体形式的散热器上,相比现有技术中多个第一光学元件分别安装在各自的散热器上,本实施例中整体形式的第一光学元件3仅通过一次安装将多个光学单元31安装在散热器5上,减小了安装误差。
在本发明的一些实施例中,作为其中的一种实施方式,如图9到图12所示,支架7上设置有螺纹连接件71和定位销72;光源组件4包括线路板42,光源41设置在线路板42上,线路板42上设置有第二穿孔421和定位孔422;散热器5上设置有第一穿孔51和定位槽52,且第一穿孔51直径大于螺纹连接件71的螺纹直径,定位槽52的直径大于定位销72的直径。螺钉8依次穿过第一穿孔51、第二穿孔421与螺纹连接件71螺纹配合拧紧,将支架7、光源组件4和散热器5连接在一起。由于第一穿孔51的直径大于螺纹连接件71的螺纹直径,也就是大于螺钉8的螺纹直径,在螺钉8拧紧以前,线路板42可以在散热器5上相对移动,来实现本实施例的调光,而螺钉8拧紧以后,二者之间的位置就固定下来,以保持调光后光形的稳定。定位销72穿过定位孔422***定位槽52中,定位销72与定位孔422相配合,使得支架7安装在线路板42上的位置定位准确,稳定性高。由于定位槽52的直径较大,定位销72能够在定位槽52中移动,使得支架7与散热器5之间的相对位置能够调节。螺钉8的头部覆盖整个第一穿孔51,使得螺钉8能够稳定地固定散热器5。螺钉8可以采用法兰面螺钉,也可以采用普通螺钉套上垫片来使用。
作为其中的另一种实施方式,散热器5、光源组件4和支架7相互固定连接形成一个整体,灯体中用于安装本发明的车灯照明装置的安装支架和散热器5上分别设置有球头螺母和球头螺杆,球头螺杆与球头螺母相连接。第一光学元件3也与该安装支架相固定,使得光源组件4与各自对应的光学单元31的光轴之间的角度能够调节。
在其中的另一种实施方式中,本发明的车灯照明装置还包括压板,散热器上设置有螺孔,压板上设置有圆孔,通过螺栓穿过圆孔与螺孔相连接,通过压板将光源组件4固定在压板与散热器5之间。松开螺栓,可以调节光源组件4相对于散热器5的位置,拧紧螺栓,可以固定二者的相对位置。
在本发明的一些实施例中,如图3到图5和图13到图15所示,第一 光学元件3由多个光学单元31一体成形,第一光学元件3的结构强度更高,光学单元31间的位置稳定性更好。
在本发明的一些实施例中,如图13到图15所示,光学单元31可以采用平凸透镜,也可以采用双凸透镜;在采用平凸透镜时,光学单元31远离光源41的一面可以为平面,也可以为凸面。各光学单元31远离光源41的一面平滑过渡形成第一光学元件3的前表面。当然,各光学单元31靠近光源41的一面也可以平滑过渡形成第一光学元件3的后表面。这使得本发明的车灯照明装置的造型更加流畅。
本发明的车辆前照灯和车辆,由于采用了本发明的车灯照明装置和车辆前照灯,因而也具有上述实施例的车灯照明装置的有益效果。
在本发明的描述中,参考术语“一个实施例”、“一些实施例”、“一种实施方式”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本发明中,对上述术语的示意性表述不一定指的是相同的实施例或示例。而且,描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
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。
