具体实施方式
在相关技术的汽车内饰中，车内灯具在不工作时，即，车内灯具在不接通电源时色泽暗淡，影响汽车内饰的装饰效果。有鉴于此，本申请实施例提供的灯具通过反射外界光线的方式，来使得灯具在不工作时，被外界的光线照射后，会产生闪亮的效果，以便提高汽车内饰的装饰性。其中，外界光线指的是，灯具外侧的光线。
可以理解地，在阳光的照射下，水面产生波光粼粼的效果，露珠产生闪亮的效果。都是由于光线在水面或露珠的表面发生反射所引起的。为了使得灯具产生闪亮的效果，则在外界光线的照射下，灯具能够反射该外界光线。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。
实施例一
图1为本申请实施例提供的一种灯具1的立体示意图，图2为图1示出的灯具1的爆炸图，图3为图1示出的灯具1的立体剖视图，图4为图1示出的灯具1的某一纵向截面图。参考图1-图4，灯具1可包括外壳11、发光组件12以及透镜13。外壳11具有开口端与封闭端，透镜13安装在外壳11的开口端，且与外壳11合围成用于容纳发光组件12的容置空间。
为了便于描述，本申请实施例以箭头X所指的方向为灯具1的左侧，则箭头X的反向为灯具1的右侧；以箭头Y所指的方向为灯具1的前侧，则箭头Y的反向为灯具1的后侧；以箭头Z所指的方向为灯具1的上侧，则箭头Z的反向为灯具1的下侧。
为了安装发光组件12，外壳11可包括相对装配的底座111与上盖112。底座111的上端可具有第一装配开口，上盖112的下端可具有与第一装配开口相对的第二装配开口。上盖112的上端可具有与透镜13相配合的开口。如此，上盖112可构成外壳11的开口端，底座111可构成外壳11的封闭端。在组装时，可先将发光组件12装配在底座111内，再将第一装配开口与第二装配开口相对合，最后可通过紧固件固定底座111和上盖112。
另外，灯光组件可包括电路板121以及灯珠122。灯珠122可焊接在电路板121的上表面131，且通电后的灯珠122可发出向上的光线。底座111的底壁可固定有朝向上方延伸的安装凸起113，电路板121可通过紧固件固定在安装凸起113上。一块电路板121上可设有多个灯珠122。多个灯珠122可间隔设置。多个灯珠122可如图2所示沿箭头X所在的方向排成一列；或者，多个灯珠122也可排列成矩阵的形式；或者，多个灯珠122也可排列成同心圆的形式。当然，多个灯珠122也可按照其它方式或形状排列，此处只是举例说明，并不对多个灯珠122的排列方式做具体限定。
此外，透镜13可如图3和图4所示从内向外穿出该开口，以使得部分透镜13位于外壳11的上端，部分透镜13位于外壳11的内部。位于开口下方的透镜13的直径，可大于位于开口上方的透镜13，以避免整个透镜13从开口穿出。当然，透镜13的下端也可整个覆盖在外壳11的开口端的上端。本申请实施例只是以透镜13穿设于外壳11的开口端为例示出，并不对透镜13与外壳11的开口端的设置方式做具体限定。
参考图3和图4，透镜13在箭头Z所在的方向上可具有相对的上表面131与下表面132，透镜13在箭头Y所在的方向上可具有相对的前表面与后表面。图3中前表面、下表面132以及后表面可形成透镜13的第二端，上表面131可构成透镜13的第一端。
其中，灯珠122发出的光线可经过透镜13的下表面132折射进入透镜13内，并经透镜13上表面131折射进入灯具1的外侧，即外界中。进入外界的灯珠122发出的光线可进入人眼，以使得人眼看见灯具1发光。另外，为了使得灯具1在灯珠122不发光时，能够出现闪亮的效果。透镜13需要有反射面14。且反射面14的反射强度越强，闪亮效果越好。由于光线在从第一介质进入第二介质过程中，光线既可能发生折射又可能发生反射。为了提高灯具1的闪亮效果，则需要加强光线在灯具1上的反射强度。
可以理解地，光由光密介质射向光疏介质时，折射角大于入射角。当入射角增大，反射光增强，折射光减弱。继续增大入射角，当折射角达到90°时，折射光全部消失，入射光全部被反射回原介质。当入射角再增大时.入射光仍被界面全部反射回原介质，这种现象叫全反射。
为了增强反射效果，可将反射面14设置在光线由光密介质射向光疏介质的位置。灯具1中，透镜13为光密介质，外壳11内的空气为光疏介质。故可将透镜13的下表面132设为反射面14。为了使得反射光线的范围尽量广，以使得整个透镜13呈现闪亮的效果，本申请实施例可通过使透镜13的下表面132具有至少两个反射面14，且至少两个反射面14之间具有预设夹角来实现。
具体而言，如果透镜13的下表面132为平面，则，射向该下表面132的外界光线只有在入射角大于临界角时，外界光线才在反射面14发生全反射。这就使得透镜13的闪亮区域只为透镜13的某一局部局域。若使得多个反射面14具有不同的倾斜角度(参考图6和图7)，不同倾斜角度的反射面14的法线不同，这就使得不同倾斜角度的反射面14发生全反射的临界角不同，就能够扩大透镜13的闪亮区域。
图5为图4示出的灯具1的部分表面的示意图，图6为一号光线71在图5示出的部分第一反射面141与第二反射面142上的示意图。参考图5和图6，可选地，多个反射面14可包括第一反射面141与第二反射面142。第一反射面141相对于透镜13的轴线的倾斜方向，可与第二反射面142相对于透镜13的轴线的倾斜方向不同。第一反射面141可为多个，多个第一反射面141可间隔设置。第二反射面142也可为多个，多个第二反射面142也可间隔设置，第二反射面142可与第一反射面141交叉排布。
示例性地，图6中，第一反射面141朝向后下方倾斜，第二反射面142朝向前下方倾斜。从透镜13的上表面131的前侧折射进入透镜13内的一号光线71，可射向第一反射面141，经第一反射面141反射可射向与该第一反射面141相邻的第二反射面142，经第二反射面142反射可射向透镜13的上表面131的右侧。从图6中的一号光线71的路线可知：在透镜13内经过两次反射的光线的行进路径的跨度，大于在透镜13内经过一次反射的光线的行径路径的跨度。跨度指的是，光线的行进路径在箭头Y所在方向的投影长度。由上可知，交叉设置两个不同倾斜方向的反射面14可进一步扩大透镜13的闪光范围。
另外，上文提到的间隔设置指的是，相邻两个第一反射面141之间具有一定间距，相邻两个第二反射面142之间具有第一间距。图6中，以相邻两个第一反射面141在箭头Y所在的方向上具有一定间距，相邻两个第二反射面142在箭头Y所在的方向上具有一定间距为例示出。当然，相邻两个第一反射面141也可在箭头X所在的方向上也可具有一定间距，相邻两个第二反射面142也可在箭头X所在的方向上也可具有一定间距。
图7为某些光线在图5示出的部分反射面14与连接面15的部分示意图。参考图7， 可选地，相邻的第一反射面141与第二反射面142之间可具有预设间距。且相邻的第一反射面141与第二反射面142之间可连接有连接面15。
具体而言，相邻的第一反射面141与第二反射面142之间的间距越大，在相邻的两个第一反射面141与第二反射面142之间反射的光线的跨度越大。当然，相邻的第一反射面141与第二反射面142之间的间距应适中，不能过大或过小。
可选地，继续参考图7，连接面15可为多个，多个连接面15可包括第一连接面151与第二连接面152。每个第一连接面151均可连接在相邻的第一反射面141的最高点与第二反射面142的最高点之间。每个第二连接面152均可连接在相邻的第一反射面141的最低点与第二反射面142的最低点之间。
示例性地，图7中，二号光线72可在第一连接面151上发生反射，三号光线可在第二反射面142、第一反射面141以及第二反射面142与第一反射面141之间的第二连接面152上发生三次反射。四号光线74可在第二反射面142与第二连接面152之间发生二次反射。由上可知，增加连接面15可增加光线在透镜13内的反射次数，进而增加光线的行进路线的多样性，以便于扩大透镜13闪光的范围。
其中，第一连接面151与第二连接面152的设置方式，可有如下几种可能的实现方式：
在其中一种可能的实现方式中，第一连接面151与第二连接面152均可为沿预设方向设置。具体而言，第一连接面151与第二连接面152可为沿预设方向设置的光滑平面或弧面。其中，光滑平面指的是，该平面的法线方向为一定值。光滑弧面指的是，该弧面的圆心和半径为一定值。
在另一种可能的实现方式中，第一连接面151可沿预设方向设置。第二连接面152可包括第一部分153、第二部分154以及第三部分155。第一部分153可与第一反射面141连接，且可相对于第一反射面141倾斜。第二部分154可与第二反射面142连接，且可相对于第二反射面142倾斜。参考图7中的四号光线74的路径，第一部分153相对于第一反射面141倾斜，第二部分154相对于第二反射面142倾斜可增加光线的反射路径的多样性。第三部分155可连接在第一部分153与第二部分154之间，且第三部分155可高于第三部分155所连的第一反射面141与第二反射面142中的最低点。参考图7中的三号光线的路径，设置第三部分155可增加光线在透镜13内的反射次数，进而增加光线的行进路线的多样性，以便于扩大透镜13闪光的范围。
其中，第二连接面152的长度可长于第一连接面151的长度。具体而言，连接面15的长度指的是，连接面15在箭头Y所在方向的投影的长度。参考图7，扩大第二连接面152的长度，可增加光线在透镜13内的反射次数。缩小第一连接面151的长度可增加第一反射面141、第二反射面142的数量。
在又一种可能的实现方式中，第一连接面151也可包括第一部分153、第二部分154以及第三部分155。与上文提到的第二连接面152的不同之处在于，连接在第一部分153与第二部分154之间的第三部分155，可低于该第一连接面151所连的第一反射面141与第二反射面142中的最低点。
继续参考图4和图5，透镜13靠近发光组件12的一端的中部可设有凹陷16，凹陷16可具有朝向发光组件12的开口。多个反射面14均可设置于凹陷16的槽底。
具体而言，凹陷16可具有朝向下方的开口，多个反射面14可形成凹陷16的槽底。 通过设置凹陷16可减少入射光线与反射面14之间的距离。另外，该凹陷16可罩设在灯珠122的外侧，以便将灯珠122发出的光线打散，并向透镜13的上表面131的不同位置折射出，以提高灯具1发出的灯光的均匀性。
另外，为了使得各个反射面14的位置有差别，透镜13的下表面132可为弧面。图5中，所有第一反射面141的最高点、所有第二反射面142的最高点可位于某条弧线上。所有第一反射面141的最低点、所有第二反射面142的最低点可位于某条弧线上。图4和图5以凹陷16的槽底为弧面为例示出。
继续参考图5-图7，可选地，预设夹角可为钝角。具体而言，光线发生全发射的条件为光线的入射角大于临界值，将第一反射面141与第二反射面142之间的夹角设置为钝角，可使得更多的光线能够发生全反射，也提高光线在透镜13内发生反射的次数。
图8为图5示出的匀光板17的示意图，参考图3、图4以及图8，透镜13的下表面132与发光组件12之间可设有匀光板17。匀光板17朝向发光组件12的表面可具有多个第一弧面171。每个第一弧面171的圆心均可朝向发光组件12设置。具体而言，多个第一弧面171可沿箭头Y所在的方向排列。匀光板17上的第一弧面171可将灯珠122发出的点光源折射成面光源，以使得灯珠122发出的灯光能够均匀地从透镜13的上表面131折射出，以提高灯具1的匀光性。另外，为了便于增加匀光板17上第一弧面171的数量，相邻两个第一弧面171可首尾连接。此外，为了使得穿过匀光板17的光线的路径多样化，匀光板17背离发光组件12的表面可具有多个第二弧面172。且每个第二弧面172的圆心均可朝向发光组件12设置。当然，为了增加匀光板17上第二弧面172的数量，相邻两个第二弧面172可首尾连接。

示例性地，控制器5可与电动汽车的电量检测器61电连接。电量检测器61可检测电动汽车的电池的电量。控制器5可在电量检测器61测得的电池的电量低于第一预设值时 (即电池缺电时)，控制该灯具1发出预设的第一光束，以提醒用户。需要说明的是，为了便于在车辆行驶时，驾驶员可以很容易地看到该灯具1发出的表示电池缺电的第一光速，可将灯具1设置在仪表板22的上表面131。
另外，控制器5还可在电量检测器61测得的电池的电量高于或等于第二预设值时(即电池充满电时)，控制该灯具1发出预设的第二光束，以提醒用户。需要说明的是，为了在用户处于车外时，也能看到灯具1在电池充满电时发出的第二光束，可将灯具1设置在仪表板22的上表面131。
此外，控制器5也可与车门检测器62电连接。车门检测器62可检测车门的开关状态。控制器5可在车门检测器62测得车门关闭时，控制灯具1发出预设的第三光束；控制器5还可在车门检测器62测得车门打开时，控制灯具1发出预设的第四光束。当然，灯具1做氛围灯使用时，还有其他的触发状态。此处只是以车门触发为例示出，并不对灯具1的触发状态做具体限定。
值得说明的是，在黑天和白天时，用户看到的灯具1发出的光不同。为了便于用户看清灯具1发出的光，汽车可包括环境检测器63。环境检测器63可设置于汽车的车身2，且用于检测外界的环境的亮度。控制器5可与环境检测器63电连接，且可用于在环境检测器63测得的外界环境的亮度低于预设值时，调节灯具1的亮度至第一亮度值。控制器5还可用于在环境检测器63测得的外界环境的亮度高于预设值时，调节灯具1的亮度至第二亮度值。
参考图9，值得说明的是，驾驶员可具有如图9中示出的眼椭圆41，与该眼椭圆41的上方相切的线为驾驶员的上视野线42，与该眼椭圆41的下方相切的线为驾驶员的下视野线43，上视野线42与下视野线43之间的区域为驾驶员的视野区。当本申请实施例提供的灯具1如图9所示安装在仪表板22的上表面131时，该灯具1会在前挡风玻璃23上形成虚像3。其中，灯具1发出的光线在挡风玻璃上的反射线的反向延长线形成虚像3。为了避免该虚像3干涉驾驶员的视野，可将灯具1发出的光线在挡风玻璃上的反射线控制在视野区的外侧。
经过本发明人的反复实践，可做如下设置：将透镜13的横截面积可沿远离发光组件12方向逐渐减小；和/或，透镜13的上表面131可光滑设置；和/或，透镜13背离发光组件12的表面平行于发光组件12的安装面设置。
其中，“上”、“下”等的用语，是用于描述各个结构在附图中的相对位置关系，仅为便于叙述的明了，而非用以限定本申请可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本申请可实施的范畴。
需要说明的是：在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
此外，在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可 以是直接相连，也可以通过中间媒介间接相连，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申请中的具体含义。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”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公开的至少一个实施例或示例中。在本说明书中，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。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
