具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其它不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
图1为本公开实施例提供的一种多功能信号灯集成照明装置的截面结构示意图，图2为本公开实施例提供的一种多功能信号灯集成照明装置的光束反射示意图。结合图1和图2，多功能信号灯集成照明装置包括：第一发光组件1、第二发光组件2和导光组件3，第一发光组件1发射第一光束a，第二发光组件2发射第二光束b，导光组件3包括反射结构31、半透半反射结构32和出射面33；反射结构31设置在第一光束a的光路上并用于将第一光束a进行反射，反射后的第一光束a透过半透半反射结构32并由出射面33射出；半透半反射结构32设置在第一光束a和第二光束b的光路上并用于将第二光束b进行反射，反射后的第二光束b由出射面33射出。图2中的虚线箭头表示反射结构31将第一光束a反射至半透半反射结构32的过程，图2中的实线箭头表示半透半反射结构32将第二光束b反射的过程。
具体地，结合图1和图2，导光组件3的反射结构31中设置在第一光束a的光路上，用于将第一光束a反射从而改变第一光束a的方向，第一光束a经过反射结构31反射后透过半透半反射结构32并由导光组件3的出射面33射出，半透半反射结构32设置在第二光束b的光路上，半透半反射结构32第二发光组件2发射的第二光束b进行反射改变第二光束b的方向的同时可以使第一光束a透过，反射后的第二光束b由出射面33射出，导光组件3的出射面33即对应车辆照明灯的出射面33，即第一光束a和第二光束b均由对应车辆照明灯的出射面33出射，点亮同一照明区域。
本公开实施例利用第一发光组件1发射第一光束a，第二发光组件2发射第二光束b，导光组件3的反射结构31设置在第一光束a的光路上用于将第一光束a进行反射，导光组件3的半透半反射结构32用于透过反射后的第一光束a并将第二光束b进行反射，第一光束a和第二光束b均由导光组件3出射面33出射。由此，本公开实施例解决了多功能信号灯点亮不均匀的问题，实现了多功能信号灯使用同一出射面33时的亮度一致，节省了造型空间，降低了成本，改善了多功能信号灯的点亮效果。
另外，相对于目前采用的多功信号灯集成照明结构，由于空间限制和造型需求，本公开实施例将第一发光组件1和第二发光组件2集成于如图1所示地同一块印刷电路板(Printed Circuit Board，PCB)5上，节省了车辆照明灯内的造型空间，降低了造型成本。
可选地，结合图1和图2，第一发光组件1发射的第一光束a平行于第二发光组件2发 射的第二光束b，由出射面33射出的第一光束a平行于由出射面33射出的第二光束b。
具体地，第一发光组件1和第二发光组件2所发射的第一光束a和第二光束b均平行，经过反射结构31反射并透过半透半反射结构32后的第一光束a与经过半透半反射结构32反射的第二光束b平行，在出射面33射出的第一光束a和第二光束b均保持平行。由此，利用同一导光组件3的出射面33实现了第一光束a和第二光束b的出射，节省了车内造型空间，实现了在同一出射面33点亮多种信号灯的需求。
可选地，如图2所示，反射结构31可以包括：多个第一反射面311，第一反射面311按第一预设间隔间隔设置，第一反射面311用于将第一光束a进行反射；第一反射面311与第一光束a呈45°角设置。
具体地，如图2所示，反射结构31包括多个按第一预设间隔间隔设置的第一反射面311，两个第一反射面311之间可以设置第三反射面312，即第一反射面311和第三反射面312交替设置，第一反射面311可以设置为全反射面以用于将第一光束a全部反射，降低第一光束a的能量损失。设置第一光束a和第一反射面311的夹角为45°从而可以改变第一光束a的方向，使第一光束a可以由出射面33平行出射，第三反射面312与第一光束a平行，对第一光束a不起反射的作用。如果不设置第一反射面311与第一光束a呈45°角，例如第一反射面311与第一光束a之间的夹角为0°时，则照射至第一反射面311的第一光束a与第一反射面311保持平行，第一反射面311无法起到反射作用，即无法改变第一光束a的方向，进而照射至第一反射面311的光束也无法从透过半透半反射结构32并由导光组件3的出射面33出射，起到车灯点亮效果。
需要说明的是，第三反射面312可以设置为反射面降低加工难度，同样也可以设置为半透半反射面以与半透半反射结构32保持一致，可以根据车辆的需求进行设置，本公开实施例对此不作限定。
可选地，如图2所示，半透半反射结构32包括：多个第二反射面321和多个第一透射面322，第二反射面321与第一透射面322交替设置，两个第二反射面321之间按第一预设间隔间隔设置，第二反射面321用于将第二光束b进行反射，第一透射面322用于透射第一光束a；第二反射面321与第二光束b呈45°角设置，第一透射面322与第一反射面311呈45°角设置。
具体地，结合图1和图2，由于第一发光组件1相比于第二发光组件2更加远离导光组件3的出射面33，第一发光组件1发出的第一光束a需要透过半透半反射结构32才能由出射面33出射，因此在透过半透半反射结构32时第一光束a可能会发生能量的损失和 角度的偏移。
基于上述问题，设置半透半反射结构32中的多个第二反射面321和多个第一透射面322间隔设置，两个第二反射面321之间按第一预设间隔间隔设置，即第二反射面321和第一透射面322交替重复排列，为了使第二反射面321将第二光束b进行反射，设置第二反射面321与第二光束b呈45°角设置，同样设置第二反射面321为全反射面，避免第二光束b在第二反射面321的能量损失，原理同第一反射面311与第一光束a的角度设置，在此不再赘述。设置第一透射面322与第一反射面311呈45°角，照射至第一反射面311的第一光束a反射至半透半反射结构32中的第一透射面322后几乎垂直透过第一透射面322，没有角度偏移，第一透射面322不再对第一光束a进一步反射，使得第一光束a经过第一透射面322时的能量损失最小。由此，可以保证第一光束a能够由出射面33正常出射，进一步改善多功能信号灯集成照明装置在主观察角度的均匀点亮。
可选地，如图2所示，可以设置两个第一透射面322之间按第一预设间隔间隔设置。
具体地，设置两个第一透射面322之间按第一预设间隔间隔设置，保证了半透半反射结构32的第二反射面321为等间距间隔设置，同时反射结构31的第一反射面311也为等间距间隔设置，且两个间距相等。由此，设置反射结构31的第一反射面311反射第一光束a，半透半反射结构32的第二反射面321反射第二光束b，第一透射面322透射第一光束a，第一透射面322与第一反射面311呈45°角设置，保证被第一反射面311反射的第一光束a可以全部进入第一透射面322，并且在透过第一透射面322时是基本垂直穿过的，第一光束a的能量损失很小且不存在光束偏移，将半透半反射结构32对第一光束a的亮度影响降到最低，优化了多功能信号灯集成照明装置的照明效果。
图3为本公开实施例提供的一种多功能信号灯集成照明装置的立体结构示意图。可选地，如图3所示，第一发光组件1包括多个第一发光结构11，第二发光组件2包括多个第二发光结构21，第一发光结构11和第二发光结构21对应的照明功能不同。
具体地，为了满足同一发光区域实现多功能信号灯照明的要求，设置第一发光结构11和第二发光结构21对应的照明功能不同，第一发光结构11和第二发光结构21可以为LED光源，第一发光结构11和第二发光结构21可以分别使用例如红色光芯的LED光源和黄色光芯的LED光源，实现了同一发光区域的多功能照明。例如可以设置第一发光结构11的LED光源的光芯颜色为红色并作为尾灯刹车或位置灯使用，设置第二发光结构21的LED光源的光芯颜色为黄色并作为转向灯使用。需要说明的是，第一发光结构11和第二发光结构21所选用的LED光源、光源的光芯颜色及对应的功能可以根据实际道路路况、交通要 求及车辆需求进行选择，本公开实施例对此不作限定。
此外，由于第一发光结构11所发出的第一光束a在穿过半透半反射结构32时会有一定的能量损失，此能量损失无法避免，因此可以设置第二发光结构21对应的光强要求高于第一发光结构11对应的光强要求。例如可以将对光强要求更高的照明功能布置在第二发光结构21处，对光强要求更弱的照明功能布置在第一发光结构11处，保证多功能信号灯集成照明装置中的第一发光结构11和第二发光结构21进行照明时均能满足应用场景要求。例如在要求刹车信号灯的光强高于转向信号灯的光强的情况下，则设置第一发光结构11具有刹车照明功能，第二发光结构21具有转向照明功能，具有刹车照明的光束和具有转向照明的光束均由同一出射面33出射。
相对于目前采用的多功信号灯集成照明装置，本公开实施例将第一发光结构和第二发光结构集成于同一块PCB 5上，降低了成本，第一发光结构11和第二发光结构21对应的照明功能不同，在实现了多功能照明的同时也避免了第一发光结构11和第二发光结构21存在偏芯的问题，提高了多功能信号灯的点亮均匀度。
需要说明的是，多个第一发光结构11和多个第二发光结构21可以沿图3所示垂直于第一方向X的方向排列，多个第一发光结构11和多个第二发光结构21也可以平行于第一方向X排列、呈L型排列或者呈弧形排列等方式排列，导光组件3的位置随第一发光结构11和第二发光结构21的排列方式的变化而变化，第一发光结构11和第二发光结构21的具体排列方式可以根据车辆的照明需求进行设置，本公开实施例对此不作限定。
可选地，结合图1至图3，多功能信号灯集成照明装置还包括：第一聚光结构61，第一聚光结构61设置在第一光束a的光路上并用于将第一光束a汇聚至反射结构31上；第二聚光结构62，第二聚光结构62设置在第二光束b的光路上并用于将第二光束b汇聚至半透半反射结构32上。图3中示例性地示出了第一聚光结构61和第二聚光结构62为正体型立体结构，图3中下方的倒梯形立体结构为一体成型的立结构，每个倒梯形立体结构上设置有反射结构31和半透半反射结构32。
具体地，由于第一发光组件1和第二发光组件2所发出的光束较为发散，因此在多功能信号灯集成照明装置中设置第一聚光结构61和第二聚光结构62汇聚第一光束a和第二光束b。示例性地，可以设置一个第一聚光结构61、一个第一发光结构11和一个反射结构31一一对应，一个第二聚光结构62、一个第二发光结构21和一个半透半反射结构32一一对应。也可以设置例如图3所示的一个第一聚光结构61和一个第一发光结构11一一对应设置，多个第一聚光结构61对应一个反射结构31，一个第二聚光结构62和一个第二发光 组件2一一对应设置，多个第二聚光结构62和一个半透半反射结构32对应设置。
具体地，第一聚光结构61和第二聚光结构62可以分别包括第一聚光面和第二聚光面，第一聚光结构61向第一发光组件1所在侧凸起并在第一光束a的光路上将第一光束a汇聚至反射结构31上，第二聚光结构62向第二发光组件2所在侧凸起并在第二光束b的光路上将第二光束b汇聚至半透半反射结构32上，第一光束a和第二光束b由导光组件3的出射面33出射，点亮照明区域。
图4为本公开实施例提供的一种多功能信号灯集成照明装置的导光组件的出射面的局部放大示意图。可选地，如图4所示，出射面33可以设置有匀光结构331。
具体地，第一光束a和第二光束b由导光组件的出射面33出射时，为了保证照明的均匀性，可以在导光组件3的出射面33设置有匀光结构331。图4中的实线箭头表示光束，目的为示出光束经过匀光结构331散射后的出射角度，第一光束a经过第一聚光结构61汇聚至反射结构31上，反射后的第一光束a透过半透半反射结构32由出射面33出射，第二光束b经过第二聚光结构62汇聚至半透半反射结构32上，反射后的第二光束b由出射面33出射。利用匀光结构331的散射功能将第一光束a和第二光束b进一步散射为多路光束出射，使光束朝着更多的方向传播，避免了光束的聚集，进一步提高了多功能信号灯集成照明装置照明的均匀性。
可选地，如图4所示，匀光结构331可以包括多个凸起结构，凸起结构朝向出射面33射出第一光束a的方向凸起。
具体地，如图4所示，可以设置匀光结构331包括多个凸起结构，凸起结构朝向出射面33射出第一光束a的方向凸起，使凸起结构可以将一路光束散射为多路不同方向的光束，由导光组件3的出射面31出射。在匀光结构331中尽量多地设置凸起结构，凸起结构的密度增大，可以使导光组件3内各个方向的光束都先经过散射后再出射，提高了出射光束的发散度，保证了照明的均匀性。匀光结构331例如可以设置凸起结构的形状为玉米粒状花纹，也可以设置凸起结构为其它形状的花纹，凸起结构的尺寸和花纹的形状根据多功能信号灯集成照明装置和车辆照明灯的造型制定，本公开实施例对此不作限定。
可选地，结合图1至图3，第一发光组件1朝向出射面33射出第一光束a的一侧设置有杂光遮挡结构4，第二发光组件2朝向出射面33射出第二光束b的一侧设置有杂光遮挡结构4，杂光遮挡结构4用于遮挡对应的发光组件发射的杂光。
具体地，第一发光组件1和第二发光组件2所发出的光线呈发散状，无论第一发光组件1与第一聚光结构61以及第二发光组件2与第二聚光结构62的相对位置如何设置，都 可能会存在第一发光组件1和第二发光组件2所发出的部分光线无法进入第一聚光结构61和第二聚光结构62的情况，一般将第一发光组件1和第二发光组件2所发出的部分无法进入第一聚光结构61和第二聚光结构62的光线视为杂光，这些杂光延第一方向X传播后出射，会干扰由导光组件3的出射面33出射的光线，造成可视亮点，影响多功能信号灯集成照明装置的照明效果。
为了解决这一问题，在第一发光组件1朝向出射面33射出第一光束a的一侧和第二发光组件2朝向出射面33射出第二光束b的一侧均设置有杂光遮挡结构4，每个杂光遮挡结构4都可以遮挡对应的第一发光组件1或者第二发光组件2发出的杂光。设置多个杂光遮挡结构4可以提高杂光遮挡的效果，进一步避免了由杂光造成的可视亮点，进一步提高了多功能信号灯集成照明装置的照明效果。
可选地，杂光遮挡结构4可以包括透明凸起筋位，透明凸起筋位表面形成有吸光膜或者透明凸起筋位的表面设置有图案化纹路。
具体地，杂光遮挡结构4包括透明凸起筋位，为了更好地遮挡第一发光组件1和第二发光组件2发出的杂光，可以在透明凸起筋位表面形成有吸光膜，例如可以在透明凸起筋位处镀一层金属膜，例如可以进行镀铝处理，可以使用热镀法、电泳法和真空蒸镀法等方法在透明凸起筋位处进行镀铝。由此，利用金属膜的吸光性，进一步吸收第一发光组件1和第二发光组件2发出的杂光，避免杂光沿出射面33射出光束的方向传播。
另外，为了进一步提高操作的简易性，降低杂光遮挡结构4的实现成本，同时也能保证透明凸起筋位起到遮挡杂光的作用，也可以在透明凸起筋位的表面设置图案化纹路，例如在透明凸起筋位处增加皮纹，皮纹可以视为细小的凸起结构，利用图案化纹路将一束将光强较强的杂光进行散射，弱化杂光的强度，降低了由杂光造成的可视亮点的影响，由此，利用图案化纹路同样可以起到遮挡第一发光组件1和第二发光组件2发出的杂光的作用。
需要说明的是，透明凸起筋位的具体尺寸和形状，透明凸起筋位表面选择形成吸光膜或者设置有图案化纹路，可根据实际操作情况设置，本公开实施例对纹路的具体造型和尺寸不作限定。
可选地，导光组件3还包括厚壁光导34，厚壁光导34的一侧为出射面33并用于传导第一光束a和第二光束b，厚壁光导34的内壁可以设置有散射结构。
具体地，第一光束a和第二光束b沿厚壁光导34传导并由出射面33出射，构成厚壁光导34的材料可以包括聚甲基丙烯酸甲酯或聚碳酸酯中的至少一种，这两种材料均为常用透明材料，第一光束a和第二光束b在厚壁光导34内部进行全反射时，由于厚壁光导34 采用透明材料而无法对第一光束a和第二光束b全部进行吸收，部分光线会由厚壁光导34的上表面和下表面出射，这些光线沿第一方向X出射后同样会造成可视亮点，影响多功能信号灯集成照明装置的照明效果，进而影响车辆照明灯的照明效果。
针对上述问题，本公开实施例在厚壁光导34的内壁上下表面设置散射结构，将厚壁光导的上表面和下表面出射的光线进行散射，弱化厚壁光导34的上表面和下表面出射的光线的强度，改善了多功能信号灯集成照明结的照明效果，进而改善了车辆照明灯的照明效果。
另外，如图1所示，可以设置厚壁光导34延第一方向X的有效长度L大于等于65毫米。厚壁光导34和半透半反射结构32相互连接为一体成型结构，厚壁光导34的有效长度L可以定义为厚壁光导34与半透半反射的连接点，与厚壁光导34出射面33与厚壁光导34上表面或者下表面的连接点的总长度，图1中示出了厚壁光导34与半透半反射的连接点，与厚壁光导34出射面33与厚壁光导34的下表面的连接点的距离作为有效长度L。
第一光束a和第二光束b进入厚壁光导34后，在厚壁光导34内部的上下表面进行多次全反射，厚壁光导34的有效长度越长，第一光束a和第二光束b在厚壁光导34内部的全反射次数越多，由厚壁光导34所出射的光线越发散，提高了多功能信号灯集成照明装置照明的均匀性。相反地，如果厚壁光导34延第一方向X的有效长度L过小，例如小于65毫米，第一个光束和第二光束b在厚壁光导34内部的反射次数较少，由厚壁光导34所出射的光线的发散度有限，聚集的光线出射后，可能在可视区域内造成部分区域过亮，部分区域过暗的问题。因此，进一步设计厚壁光导34的有效长度L大于等于65毫米，可以进一步保证多功能信号灯集成照明装置照明的均匀性，从而保证车辆照明灯照明的均匀性。
可选地，散射结构可以为形成于厚壁光导34内壁的图案化纹路。
具体地，为了起到更好地散射效果，设置散射结构为图案化纹路，图案化纹路形成于厚壁光导34内壁的上表面和下表面，由厚壁光导34的上表面和下表面出射的光束经过图案化纹路的散射作用后，一束较强的光束会被散射为多个角度的光束，延第一方向X传播的光束的强度也随之变弱，弱化的光束延第一方向X出射时，所造成的可视亮点的亮度也更弱，对车辆照明灯的照明效果影响较小。
本公开实施例设置多功能信号灯集成照明装置包括第一发光组件1、第二发光组件2和导光组件3；第一发光组件1发射第一光束a，第二发光组件2发射第二光束b，导光组件3包括反射结构31、半透半反射结构32和出射面33；反射结构31设置在第一光束a的光路上并用于将第一光束a进行反射，反射后的第一光束a透过半透半反射结构32并由出射面33射出半透半反射结构32设置在第一光束a和第二光束b的光路上并用于将第二光束 b进行反射，反射后的第二光束b由所述出射面33射出。由此，利用导光组件3中的反射结构31和半透半反射结构32分别将第一光束a和第二光束b反射，反射后的第一光束a透过半透半反射结构32后与反射后的第二光束b由同一出射面33出射，解决了多功能信号灯点亮不均匀的问题，实现了多功能信号灯使用同一出射面33出射时的亮度一致，节省了造型空间，改善了多功能信号灯的点亮效果。
