与现有技术相比，本申请的有益效果为：
本申请提供的车灯，基板的一侧端面上设置有至少一个导热管，即沿着垂直于基板的方向上形成导热管-基板-导热管的结构，与现有的两个基板夹设有一个导热管的结构相比，本申请的这种结构的导热能力更强，导热效率更高，并且散热效率更高，这有助于延长车灯的使用寿命。同时，车灯整体结构牢固，结构的防震效果好，对焦精准，能够提供良好的光型，可以完美替换原有的卤素灯或氙气灯，适用于各种车型，提升了用户的使用体验和满意度，同时，提高了市场的竞争力。具体地，发光芯片发光后，产生大量热量，热量传递至基板上，基板再将热量分别传递给基板两侧的导热管，导热管充分吸收热量，并且迅速传导给散热组件，热量可以更快的速度耗散在大气中，从而降低发光芯片的温度，提升光效同时可以获得更高的整体功率即提升亮度，散热效率提高则延长了车灯的使用寿命。

实施例一
图1为本申请实施例一提供的车灯的结构示意图；图2为本申请实施例一提供的车灯的又一结构示意图；图3为本申请实施例一提供的车灯的又一结构示意图；图4为本申请实施例一提供的车灯的又一结构示意图；图5为本申请实施例一提供的车灯的爆炸图；图6为本申请实施例一提供的车灯的又一爆炸图。参见图1至图6所示，本申请实施例一提供了一种车灯，包括基板1、发光芯片2、至少两个导热管3以及散热组件4；其中，发光 芯片2设置在基板1上；基板1的一侧端面上设置有至少一个导热管3；导热管3与散热组件4相连接。
本申请提供的车灯，本申请的基板1的一侧端面上设置有至少一个导热管3，即沿着垂直于基板的方向上形成导热管3-基板1-导热管3的结构，较现有的两个基板1夹设有一个导热管3的结构，导热能力更强，散热效率更高，有助于延长车灯的使用寿命。具体地，发光芯片2发光后，产生大量热量，热量传递至基板1上，基板1再将热量分别传递给基板1两侧的导热管3，导热管3吸收热量并迅速传导给散热组件，加之散热组件的散热作用，从而降低发光芯片2的温度，延长了车灯的使用寿命。具体而言，当基板1一侧的导热管3的数量为多个；多个导热管3沿基板1的长度方向均匀排布，或多个导热管3沿基板1的宽度方向均匀排布。为了提高车灯的亮度，可以设置多个基板1，每个基板1上均设置有发光芯片2，具体而言，当基板1的数量为两个时，两个基板1并行排布；当基板1的数量为多于两个时，多个基板1并行排布；或多个基板1顺次相连接并围设成棱柱状结构。尤其对于多个基板1围设成棱柱状的结构，使得基板1上的发光芯片2，沿着棱柱状结构的周向均匀分布，实现了360°范围内的照明，增加了车灯的亮度，同时由于每个基板1的每一侧均设置有多个导热管3，又能提高导热能力，保证发光芯片2的散热，延长车灯的使用寿命。具体而言，发光芯片2的数量至少为一个，对于多个发光芯片2，其可分别设置在所述基板1的两侧。基板1上可设置有凹槽，部分导热管3位于所述凹槽内。导热管可以做得很薄，能够满足各款汽车头灯总成的各型号自由曲面的X轴、Y轴、Z轴的精准对焦，并提供良好的光型，以替代原有的卤素大灯或HID大灯。
该实施例中，导热管3包括顺次相连通的蒸发腔和冷凝腔(图中未示出)；蒸发腔的横截面与冷凝腔的横截面均呈扁平状，且蒸发腔的延伸方向与冷凝腔的延伸方向一致；蒸发腔的内表面与冷凝腔的内表面均设置有毛细芯层；蒸发腔与冷凝腔相连通，蒸发腔与冷凝腔均为真空状态，且蒸发腔内填充有冷却液；蒸发腔的内表面的毛细芯层与冷凝腔的内表面的毛细芯层相连接。具体而言，热管由中空的壳体制成，该中空的壳体包括蒸发端和冷凝端，蒸发端的内部形成蒸发腔，冷凝端的内部形成冷凝腔；蒸发腔的横截面的形状大小和冷凝腔的横截面形状大小相同；蒸发腔的延伸方向与冷凝腔的延伸方向一致，也就是说，蒸发腔的长度方向与冷凝腔的长度方向一致。蒸发腔的内表面的毛细芯层与冷凝腔的内表面的毛细芯层相连接，这样冷却液能够从冷凝腔的内表面的毛细芯层流向蒸发腔的内表面的毛细芯层。为保证冷却液的气液循环过程，并加快热传导效率，蒸发腔和冷凝腔应保持合适的厚度。
其中，通过将蒸发腔的横截面设计成扁平状，方便了发热元件器的安装，发热元件能够与蒸发腔的外表面充分接触，将热量传递给蒸发腔，而将冷凝腔设计成扁平状使得散热 器的散热翅片能够充分与冷凝腔的外表面进行最大程度的进行热交换，另外，由于使蒸发腔的延伸方向与冷凝腔的延伸方向一致，使得蒸发腔的内表面的毛细芯层的冷却液能够直线传输到冷凝腔的内表面的毛细芯层中，加快了冷却液的循环，从而提高了散热效果，延长了热管的使用寿命。
该实施例中，导热管还包括冷凝延伸腔(图中未示出)，冷凝延伸腔与冷凝腔相连通，且冷凝腔位于蒸发腔与冷凝延伸腔之间；冷凝延伸腔的内表面设置有毛细芯层，冷凝腔的内表面的毛细芯层与冷凝延伸腔的内表面的毛细芯层相连通。具体而言，蒸发腔、冷凝腔与冷凝延伸腔的材质均为铜；或，蒸发腔、冷凝腔与冷凝延伸腔的材质均为铝。该实施例可选的方案中，毛细芯层的材质为铜或铝。该实施例可选的方案中，冷却液的材质为水。蒸发腔、冷凝腔与冷凝延伸腔由钢管或铝管制成。需要说明的是，冷却液也可以采用其他的具有气液两相相变性能的物质，如乙醇、丙酮等，可以根据热源的发热温度以及相变材料的相变温度进行选择。可见，本申请实施例提供的热管，采用相变散热方式及毛细结构传输的原理为：冷却液吸纳于蒸发腔的内表面的毛细芯层中，当热管的蒸发腔的外表面受热时，蒸发腔的内表面的毛细芯层中的冷却液吸热气化，气化的冷却液从毛细芯层中溢出，顺着蒸发腔向冷凝腔的方向流动，并在冷凝腔和冷凝延伸腔中放热冷凝液化，液化的冷却液被吸入冷凝腔和冷凝延伸腔的毛细芯层中，再通过毛细芯层的毛细作用向蒸发腔的毛细芯层输送，从而完成一个散热冷却循环。
该实施例中，如图5和图6所示，散热组件4包括：基座401、散热体402、风扇403以及风扇罩404；其中，散热体402设置在基座401上，用于散热，此外，基座401用于安装活动卡盘5；风扇403设置在散热体402背离基板1的端部，进行热对流起到加快散热的作用；风扇罩404罩设在风扇403的外部，防止灰尘、杂质进入风扇403内部，影响风扇403的工作。具体而言，基座401内设置有安装槽，基板1以及导热管3能够插设在安装槽内；或基座401内设置有通口，导热管3还可穿过此通口与散热体402焊接或者胶粘在一起，但不仅限于此。具体而言，基座401与散热体402为一体式结构，结构强度高，不容易损坏，当然，不仅限于此。
其中，可选的方案中，汽车头灯还包括风扇403固定架(图中未示出)，风扇403固定于风扇403固定架上，风扇403固定架安装于散热体402上。车灯还包括导风环(图中未示出)，散热体402设置于导风环中，能够利用于使风扇403产生的气流定向流动提高散热效果。
该实施例中，基板1与基座401焊接在一起；或基板1与基座401胶粘在一起。方便加工制造，且能够保证基板1与基座401稳定地连接在一起。具体而言，基板1、基座401以及散热体402顺次焊接在一起；或基板1、基座401以及散热体402顺次胶粘在一起。 当然，不仅限于此。
该实施例中，散热体402为多组散热翅片集成在一起的结构，达到强化传热的目的。具体而言，多个散热翅片均呈放射状分布，使得散热器整体呈圆柱体状；翅片可以采用钢带、不锈钢带、铜带或铝带等；当然，不仅限于以上所述的结构与材质。
该实施例中，如图5和图6所示，车灯还包括活动卡盘5，活动卡盘5包括主体501和多个限位卡环502；其中，主体501为内部中空的环状结构，所述主体501套设在所述基座401上；多个限位卡环502设置在主体501的外壁面上，多个限位卡环502用于与车辆上的车灯安装座相卡接限位，从而将组装完成后的车灯安装在车辆的车灯安装座上。具体而言，多个限位卡环502沿着主体501的轴向排布，当然，不仅限于此。
该实施例中，如图3、图5以及图6所示，车灯还包括紧固件6，活动卡盘5通过紧固件6与基座401相连接，进一步防止活动卡盘5从基座401上脱落。具体而言，紧固件6为螺钉，当然，不仅限于此。
该实施例中，导热管3与基板1焊接在一起；或导热管3与基板1胶粘在一起。使得导热管3与基板1连接得更稳固，进一步防止导热管3脱落。
该实施例中，车灯还包括配电盒(未示出)；配电盒分别与发光芯片2和风扇403电连接。当车灯安装在车辆上后，配电盒与汽车电源相连接，通过汽车电源向配电盒供电。
