请参阅图1所示，本发明还包括外配光镜50和灯壳60，所述外配光镜50位于所述装饰框40的外侧；所述灯壳60与所述外配光镜50连接，所述光源组件10、所述导光元件20、所述内配光镜30以及所述装饰框40分别容置于由所述灯壳60和所述外配光镜50围合成的空腔内。
基于上述车灯，本发明还提供一种具有上述车灯结构的汽车。
综上所述，本发明的导光元件20分隔出多个独立的光通道，能够使光源11的边界更清晰、锐利，同时光通道能够抑制光束的散射，避免光束外溢至未点亮区域，进而避免出现漏光、白斑等现象，提高显示图形的对比度；同一个光源11的各LED灯珠可以同时点亮，也可以单独点亮，或者以不同的明暗程度点亮，以满足不同的灯光颜色需求；内配光镜30由透明材料或光扩散材料制成，能够使光效更均匀，避免出现亮斑；掩光层31能够进一步修饰点亮区域的轮廓，使其边界更清晰，进一步提升显示效果；装饰框40能够使每个像素呈现出不同的外观样式。所以，本发明有效克服了现有技术中的一些实际问题从而有很高的利用价值和使用意义。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
在本文的描述中，提供了许多特定细节，诸如部件和/或方法的实例，以提供对本发明实施例的完全理解。然而，本领域技术人员将认识到可以在没有一项或多项具体细节的情况下或通过其他设备、系统、组件、方法、部件、材料、零件等等来实践本发明的实施例。在其他情况下，未具体示出或详细描述公知的结构、材料或操作，以避免使本发明实施例的方面变模糊。
在整篇说明书中提到“一个实施例”、“实施例”或“具体实施例”意指与结合实施例描述的特定特征、结构或特性包括在本发明的至少一个实施例中，并且不一定在所有实施例中。因而，在整篇说明书中不同地方的短语“在一个实施例中”、“在实施例中”或“在具体实施例中”的各个表象不一定是指相同的实施例。此外，本发明的任何具体实施例的特定特征、结构或特性可以按任何合适的方式与一个或多个其他实施例结合。应当理解本文所述和所示的发明实施例的其他变型和修改可能是根据本文教导的，并将被视作本发明精神和范围的一部分。
还应当理解还可以以更分离或更整合的方式实施附图所示元件中的一个或多个，或者甚至因为在某些情况下不能操作而被移除或因为可以根据特定应用是有用的而被提供。
另外，除非另外明确指明，附图中的任何标志箭头应当仅被视为示例性的，而并非限制。此外，除非另外指明，本文所用的术语“或”一般意在表示“和/或”。在术语因提供分离或组合能力是不清楚的而被预见的情况下，部件或步骤的组合也将视为已被指明。
如在本文的描述和在下面整篇权利要求书中所用，除非另外指明，“一个”、和“该”包括复数参考物。同样，如在本文的描述和在下面整篇权利要求书中所用，除非另外指明，“在…中”的意思包括“在…中”和“在…上”。
本发明所示实施例的上述描述(包括在说明书摘要中所述的内容)并非意在详尽列举或将本发明限制到本文所公开的精确形式。尽管在本文仅为说明的目的而描述了本发明的具体实施例和本发明的实例，但是正如本领域技术人员将认识和理解的，各种等效修改是可以在本发明的精神和范围内的。如所指出的，可以按照本发明所述实施例的上述描述来对本发明进行这些修改，并且这些修改将在本发明的精神和范围内。
本文已经在总体上将系统和方法描述为有助于理解本发明的细节。此外，已经给出了各种具体细节以提供本发明实施例的总体理解。然而，相关领域的技术人员将会认识到，本发明的实施例可以在没有一个或多个具体细节的情况下进行实践，或者利用其它装置、系统、配件、方法、组件、材料、部分等进行实践。在其它情况下，并未特别示出或详细描述公知结构、材料和/或操作以避免对本发明实施例的各方面造成混淆。
因而，尽管本发明在本文已参照其具体实施例进行描述，但是修改自由、各种改变和替换亦在上述公开内，并且应当理解，在某些情况下，在未背离所提出发明的范围和精神的前提下，在没有对应使用其他特征的情况下将采用本发明的一些特征。因此，可以进行许多修改，以使特定环境或材料适应本发明的实质范围和精神。本发明并非意在限制到在下面权利要求书中使用的特定术语和/或作为设想用以执行本发明的最佳方式公开的具体实施例，但是本发明将包括落入所附权利要求书范围内的任何和所有实施例及等同物。因而，本发明的范围将只由所附的权利要求书进行确定。
