具体实施方式
以下，参照附图对本发明的实施方式所涉及的车辆用照明系统进行详细的说明。此外，各附图的目的在于说明各构件的位置关系，因此未必表示实际的各构件的尺寸关系。另外，在各实施方式的说明中，对同一或者对应的构成要素标注同一附图标记，并适当地省略重复的说明。
图1是用于对本发明的实施方式所涉及的车辆用照明系统100进行说明的图。如图1所示，具备在车辆101的附近飞行的无人飞行器10、以及设置于车辆101的光源装置12。无人飞行器10具备对于来自车辆101的光源装置12的光进行反射而对车辆101的周围进行照射的反射构件11。
根据该车辆用照明系统100，能够在车辆101的周围描绘图形和/或文字而提醒司机、行人等注意。借助在车辆101的附近飞行的无人飞行器10进行照射，因此对于通过车辆101所搭载的车辆用灯具单体而难以照射到的区域也能够照射文字、图形等。例如在十字路口，通过在相对于车辆而成为死角的区域照射“STOP”等文字、表示车辆正在接近的箭头等，能够提醒其他车辆的司机、行人注意。
图2是用于对搭载于车辆101的光源装置12进行说明的图。在本实施方式中，光源装置12配置于在车辆101的前方配置的头灯的灯室13内。灯室13形成于灯体14以及将灯体14的前面开口部覆盖的透明的罩15的内侧。但是，光源装置12的位置不限定于头灯的灯室13内，例如还可以配置于车辆101的前窗玻璃的上部等。
光源装置12具备：对光源装置12的各构成要素进行支承的支承构件16；射出多个激光而能够改变照射光的颜色的激光光源单元17；由MEMS镜等构成、使得来自激光光源单元17的激光进行扫描而在照射对象上描绘线、画等图形的光源侧光扫描设备18；以及对激光光源单元17、光源侧光扫描设备18等进行控制的控制单元20。
激光光源单元17、光源侧光扫描设备18以及控制单元20安装于支承构件16。支承构件16经由调光螺钉(aiming screw)21而安装于灯体14。
激光光源单元17具备红色激光器22、绿色激光器23、蓝色激光器24、红色用透镜26、绿色用透镜27、蓝色用透镜28、红色用二向色镜30、绿色用二向色镜31、以及蓝色用二向色镜32。
从红色激光器22射出的红色激光透过红色用透镜26而转换为平行光之后，被红色用二向色镜30朝向光源侧光扫描设备18反射。从绿色激光器23射出的绿色激光透过绿色用透镜27而转换为平行光之后，被绿色用二向色镜31朝向光源侧光扫描设备18反射。从蓝色激光器24射出的蓝色激光透过蓝色用透镜28而转换为平行光之后，被蓝色用二向色镜32朝向光源侧光扫描设备18反射。通过二向色镜，将红色光(R)、绿色光(G)以及蓝色光(B)的三色混合而生成白色的激光LB。
光源侧光扫描设备18为MEMS镜，具备使得来自激光光源单元17的激光LB朝向无人飞行器10的反射构件11反射的反射构件35。光源侧光扫描设备18通过使反射构件35上下左右地往复转动而与后述的无人飞行器10的飞行器侧光扫描设备协同地以在路面上、壁面上描绘所希望的文字、图形的方式使激光LB进行扫描。此外，除了MEMS镜以外，光源侧光扫描设备18也可以采用电流镜(galvano mirror)等各种各样的光扫描设备。
另外，光源装置12具备用于对无人飞行器10进行拍摄的照相机19、红外线激光器25、红外线用透镜29、红外线用二向色镜33以及红外线受光部34，上述部件构成用于确认无人飞行器10的位置的LIDAR(Light Detection And Ranging)系统。
从红外线激光器25射出的红外线激光透过红外线用透镜29而转换为平行光之后，被红外线用二向色镜33朝向光源侧光扫描设备18反射。该红外线激光被光源侧光扫描设备18的反射构件35朝向无人飞行器10反射。被无人飞行器10反射的红外线激光经由反射构件35、二向色镜等而被红外线受光部34检测到。控制单元20对红外线受光部34所检测到的反射红外线激光进行解析而确认无人飞行器10的位置。通过利用由照相机19拍摄到的无人飞行器10的图像，能够更加准确地确认无人飞行器10的位置。控制单元20基于无人飞行器10的位置信息而对无人飞行器10的飞行状态进行控制。
图3是用于对无人飞行器10进行说明的图。无人飞行器10可以是无人机，基于来自在车辆101上搭载的光源装置12的控制单元20的控制信号而在车辆101的周围飞行。
无人飞行器10具备飞行器侧光扫描设备42。飞行器侧光扫描设备42具备对来自车辆101的光源装置12的激光LB进行反射的反射构件11。飞行器侧光扫描设备42通过使反射构件11上下左右地往复转动而与光源装置12的光源侧光扫描设备18协同地以在路面上、壁面上描绘所希望的文字、图形的方式使激光LB进行扫描。此外，除了MEMS镜以外，飞行器侧光扫描设备42也可以采用电流镜等各种各样的光扫描设备。
在本实施方式所涉及的车辆用照明系统100中，例如还可以设为使无人飞行器10常驻于十字路口，当车辆101接近该十字路口时由光源装置12的控制单元20对飞行状态进行控制。或者，无人飞行器10也可以始终在车辆101的周围飞行。或者，也可以是，无人飞行器10在通常情况下收纳在车辆101内，仅在必要情况下从车辆101起飞。无人飞行器10根据来自控制单元20的控制，在规定的位置飞行，反射来自车辆101的光源装置12的激光LB而在路面、壁面上照射图形和/或文字而提醒司机、行人等注意。根据本实施方式所涉及的车辆用照明系统100，经由在车辆101的周边飞行的无人飞行器10进行照射，因此，与利用设置于车辆101的灯具直接对路面等进行照射的情况相比，能够对更加广阔的区域照射文字、图形等信息。
另外，在本实施方式所涉及的车辆用照明系统100中，由于是反射来自车辆101的光源装置12的光的结构，因此无需在无人飞行器10上设置光源。因而，能够实现无人飞行器10的轻量化、低耗电化。
进一步地，本实施方式所涉及的车辆用照明系统100构成为从上空照射光，因此具有不易对行人造成目眩的优点。
在上文中对为了提醒注意而照射文字、图形的实施方式进行了说明，但也可以是单纯地照射点光那样的光的实施方式。在该情况下，能够对通过设置于车辆101的灯具而难以直接照射的区域照射光，因此能够提高行人、障碍物的视觉辨认性。
以上，以实施方式为基础对本发明进行了说明。上述实施方式为示例，本领域技术人员应当能够理解可以在各构成要素、各处理流程的组合的基础上实施各种变形例，并且这样的变形例也包括在本发明的范围内。
例如，在上述实施方式中，在车辆101中搭载的光源装置12构成为将RGB的三色混合而照射白色的激光。但是，光源装置12的结构并不局限于此，例如也可以构成为照射蓝色光或者紫色光的激光。在该情况下，通过在搭载于无人飞行器10的反射构件11中设置将蓝色光或者紫色光转换为白色光的波长转换层而能够照射白色光的激光。
另外，在上述实施方式中，光源装置12构成为照射激光，但是光源装置12所照射的光并不限定于激光，例如也可以是来自LED的照射光。
