  • pixelated signal lights have also been developed. The multi-pixelization of signal lights makes the functions and forms of signal lights more diverse, more technological and futuristic.
  • Matrix headlights means that the car light shape is divided into multiple light shape areas, and the lights of each light shape area can be independently controlled to turn on and off, forming a light distribution with one or more dark areas.
  • ADB can detect the environment of the vehicle and the conditions of other road users based on the detection probe, and control the lights to form different light distributions based on the detected information. In this way, the light shape can be changed according to the environment of the vehicle to avoid the dazzling of other road users, while improving the visual experience of the driver of the vehicle and driving safety.

It is also necessary to provide a heat dissipation fan, so that this kind of lighting device occupies a large space.

本申请要求2019年11月27日提交的中国专利申请201922119431.0和2020年1月9日提交的中国专利申请的202020045138.4的权益，该两件申请的内容通过引用被合并于本申请。
技术领域
本发明涉及车辆照明系统，具体地，涉及一种车辆照明装置。本发明还涉及一种车辆不可见光投射装置及一种目标物检测装置。
背景技术
近年来，矩阵式大灯(Matrix大灯)和自适应远光灯(ADB)照明技术逐渐发展起来，其能够根据道路上其他道路使用者的位置自动调整灯光的照射范围，提高了驾驶安全性，也为智能驾驶奠定了基础。另外，像素化的信号灯也得到了一定发展，信号灯的多像素化，使得信号灯的功能和形式变得更多样，更具科技感和未来感。
矩阵式大灯是指车灯光形被划分为多个光形区域，并能够独立控制各个光形区域的灯光的亮灭，形成带有一个或多个暗区的光分布。ADB能够根据检测探头检测车辆所处环境和其他道路使用者的情况，并根据检测到的信息控制车灯形成不同的光分布。这样就能够根据车辆所处环境变换光形，以避免其他道路使用者的炫目，同时改善本车驾驶员的视觉体验，提高驾驶安全性，比如，在前方无其他道路使用者时，矩阵式大灯照亮全部光形区域，当前方出现对向来车时，矩阵式大灯动态关闭对向来车对应的区域的光形，实现局部暗掉，其余区域点亮的光形，以防止灯光刺激对向来车驾驶人的眼睛，从而提高驾驶安全性。
现有的矩阵式大灯或者像素化信号灯，大多采用矩阵式的发光单元，通过多行多列的发光单元对应相应的照明区域或相应的像素。而现有的发光单元的面积还比较大，相邻的发光单元之间也存在较大的间隙，这就需要与每个发光单元相对应的设立多个初级光学元件，将每个发光单元所发出的光引导到一个较为紧凑的区域，实现矩阵式大灯或者像素化信号灯的功能。这种技术方案主要存在如下不足：(1)设置了大量的发光单元和初级光学元件，导致成本较高，体积和重量均比较大；(2)大量发光单元的设置，使得照明装置的热量较高，且发光区域集中，散热较为困难，而大量采用的高分子材料的初级光学元件，较易受到热的影响；(3)设置大量的发光单元，相适应性的，散热器也很大，还需要设置散热风扇，使得这种照明装置的占用空间较大。
还有一种采用少数几个发光单元发光，通过可旋转反射器将每个发光单元所发出的光线向一定的区域反射，并配合对各个发光单元的亮灭的控制来实现多个照明区域的照明或者区域显示功能的技术。相比于传统的矩阵式大灯或者像素化信号灯，其发光单元数量有所减少，但仍存在如下不足：(1)设置发光单元、旋转反射器和相应支架，使得照明装置整体的空间占用比较大；(2)旋转反射器的结构较复杂，尤其是与光的反射区域相对应的反射面，设计和加工难度大。存在照明装置的结构不够简单的缺陷，不利于市场的大范围扩展、推广。
另外，现有的Matrix大灯和ADB所形成的照明暗区形成了一种车辆驾驶人无法观察到的区域，驾驶人无法判断暗区内的道路使用者的活动情况，也无法识别暗区内的障碍物，给行车安全带来了新的影响。夜间车辆行驶时车灯的照射范围有限，特别是使用远光照明时，远光灯的照射范围较小。驾驶人不能观察到的远光照射范围外的道路使用者也可能成为行车安全的隐患，特别是该道路使用者横向运动时。这些都形成了现有的Matrix大 灯和ADB在安全方面的缺陷，影响了其市场应用和推广。

具体实施方式
在本发明中，在未作相反说明的情况下，使用的方位词如“上”、“下”、“左”、“右”、“前”、“后”所指示的方位或位置关系是基于本发明在使用状态下的方位或位置关系。其中，车辆的正常行驶方向为“前”。
在本发明中，术语“配光元件”是指一种能够使光线的全部或者一部分发生传播方向改变，以改变原有的光线分布的光线元件。其改变光线传播方向的方式可以是反射，可以是折射，也可以是其他任何可能的方式。术语“聚光件”是在光线通过时，指能够使光线在至少一个方向上产生汇聚作用的光学器件。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“连接”等应做广义理解，例如，术语“连接”可以是固定连接，也可以是可拆卸连接，或者是一体连接；可以是直接连接，也可以是通过中间媒介间接连接，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发明中的具体含义。
下面结合附图对本发明的具体实施方式进行详细说明，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，本发明的保护范围并不局限于下述的具体实施方式。
如图1、图2所示，本发明的车辆照明装置的一种实施方式包括光源1、旋转执行器2、配光元件3和控制器。光源1上设置有多个依次排列的能够独立发光的发光单元11。发光单元11选用能够快速发光和快速熄灭的发光元件，优选具有足够的发光强度并且体积较小的发光元件。在本发明中可以选用LED、激光二极管等。配光元件3设置在光源1的临近位置，用于对发光单元11发出的光线进行汇聚，一方面能够提高发光单元11所发出的光线的照明亮度，一方面能够避免不同发光单元11所发出的光线间的相互影响，提高所形成的光形的精度。配光元件3可以是设置在光源1侧面的反光杯31，可以是设置在光源1前面的聚光件32，也可以是其他任何可能的能够使光线发生汇聚的器件。光源1安装在旋转执行器2的旋转轴上，能够在旋转执行器2的驱动下高速旋转。多个发光单元11从光源1的旋转中心向外周排列，在本实施方式中，对发光单元11的具体排列方式并不进行限制，但最外侧的发光单元11距旋转中心的直线距离决定了发光范围。发光单元11之间的间隙可以相等，也可以不相等，本领域技术人员可以根据光学性能自行进行调整。为保持光源1在高速旋转状态下的平衡，光源1的发光单元11布置区域的对侧需要保留相应的空白区域。配光元件3可以安装在旋转执行器2上，也可以安装在光源1上，以能够随光源1同步旋转。在设置配光元件3时也应该考虑在旋转执行器2旋转状态下的平衡。旋转执行器2选用能够高速旋转并能够反馈旋转状态的旋转驱动器件，如带有转速反馈电极的直流电机。也可以使用伺服电机等转速可精确控制的旋转驱动器件。控制器(附图中未画出)能够接收到旋转执行器2的转速信号，并根据旋转执行器2的转速分别控制各个发光单元11在各个时刻的点亮或熄灭，使得各个发光单元在一定时间内在旋转的相同位置的亮灭状态相同，在视觉暂留原理的作用下，形成了固定的光形。变换各个发光单元11在特定时刻的亮灭状态，即可变换所形成的光形；控制单位时间段内各个发光单元11的亮灭状态按一定的规律缓慢变化，还可以形成动画光形。在在旋转执行器2的转速达到25转/秒，即1500转/分时，即可形成较为稳定的光形。旋转执行器2的转速越高，光形的稳定性越佳，在本实施方式中，推荐使用3000转/分的转速。如图3所示，旋转执行器2可以以顺时针方向旋转，也可以以逆时针方向旋转，其旋转方向仅与控制器的控制程序有关，并不会影响本发明功能的实现。单位长度上发光单元11个数的增加可以提高本发明的车辆照明装置的照射精度或显示分辨率。使用能发出高亮度白光的发光单元11，本发明的车辆照明装置可以用来替代矩阵式大灯，使用较低亮度彩色发光单元11，本发明的车辆照明装置可以用来替代像素化信号灯。控制器使用在当前广泛使用的51系列单片机，在本实施方式中使用MCS-51单片机，其控制和编程方法已为相关领域的技术人员所熟知，且本发明并未在此方面做出改进，故而在此不再赘述。
如图1和图2所示，本发明的车辆照明装置还可以带有支架6，旋转执行器2安装在支架6上，并通过支 架6固定在灯体上。相关部件之间的连接采用焊接、铆接、螺钉连接或胶接等常规连接方式，以实现本说明书叙述的功能为限。光源1的供电采用现有的可在旋转状态下供电器件，优选采用导电滑环来向光源1供电。供电结构附图中未标出。控制器可以集成在光源1的线路板上，也可以集成在旋转执行器2内，或者以独立的线路板的形式外接在装置有外部。
在本发明的车辆照明装置的一些实施例中，如图1、图2所示，本发明的车辆照明装置还包括安装板4，安装板4的中心固定在旋转执行器2的旋转轴上，光源1和配光元件3安装在安装板4上，光源1上的发光单元11沿安装板4的中心向一侧的边缘排列，配光元件3设置在发光单元11排列方向的两侧。旋转执行器2旋转时，带动安装板4旋转，进而带动光源1和配光元件3绕旋转执行器2的旋转轴一同旋转。安装板4可以使用带有一定机械强度的绝缘材料制成，优选采用高导热绝缘塑料，一方面可以较好地固定在旋转执行器2的旋转轴上，另一方面能更好地对光源1形成支撑，防止光源1在高速旋转过程中的振动或者变形，保证所形成的光形的稳定。
在本发明的车辆照明装置的一些实施例中，光源1的每个发光单元11位于转执行器2的不同旋转半径上。此时，在旋转执行器2旋转一周时，每个发光单元11的旋转轨迹均形成一个不同半径的圆，在旋转过程中的每一个时刻每个发光单元11均构成旋转平面内的一个不同的像素。因此，所形成的光形的分辨率更高。各个发光单元11可以设置在一条一端通过旋转执行器2旋转轴的线段上，也可以设置在多条一端通过旋转执行器2旋转轴的线段上，甚至还可以散布在以旋转执行器2的旋转轴为圆心的圆上。因为发光单元11占有一定的面积，而且相邻的发光单元11之间存在一定的间隙，限制了在一条半径方向上能够设置的发光单元11的数量，也就限制了车辆照明装置的照明光形的精度或者显示的分辨率。通过将发光单元11分散设置在不同的位置上，能够使得处于不同的旋转半径上的发光单元11的数量更多，通过对不同半径上的发光单元11的特别控制，就相当于在同一条半径上提高了发光单元11的设置密度，能够有效地提高车辆照明装置的照射精度或者显示的分辨率，以突破发光单元11的封装体积和设置距离的限制，获得更大的光形分辨率。
在本发明的车辆照明装置的一些实施例中，如图4至图6所示，光源1的各个发光单元11分为两个以上的组，每个组安装在旋转执行器2的旋转平面的不同区域，并且每个组内的各个发光单元11具有不同的旋转半径。不同组间的各个发光单元11可以具有相同的旋转半径，也可以具有不同的旋转半径，但在具有相同的旋转半径时通常每个组的发光单元11的数目相等，且对应的发光单元11均具有相同的旋转半径。每个组的发光单元11可以沿旋转执行器2旋转圆的一个半径线性排列，也可以在旋转执行器2的旋转平面不同区域按其他排列方式排列，如发光单元11还可以采用倾斜布置、渐开线布置等多种由圆心到圆周的布置方式，各个发光单元11在圆周上的相对位置也可以多种多样，以丰富本发明的车辆照明装置的照明和/或信号功能。
作为本发明的车辆照明装置的一种实施方式，如图4至图6所示，多个发光单元11分为至少两个分组，每个组中对应的发光单元11在旋转执行器2的旋转圆周上对称设置。例如，如图4所示，光源1的各个发光单元11沿以旋转执行器2的旋转轴为中点的线段线性排列，也就是发光单元11排列在光源1绕旋转执行器2的旋转轴旋转产生的旋转圆的两个对称的半径排列。或者如图5所示，光源1的各个发光单元11沿从旋转执行器2的旋转轴出发的依次成120°的三条等长线段排列，也就是发光单元11排列在光源1绕旋转执行器2的旋转轴旋转产生的旋转圆的成中心对称的三条半径排列。或者如图6所示，设置一个圆形的安装板4，将安装板4的圆心固定在旋转执行器2的旋转轴上，光源1从安装板4的圆心向圆周方向布置在旋转执行器2旋转圆的6个对称的半径上。将发光单元11设置在相对称的半径上能够保证光源1在旋转状态下的平衡，控制器的编程也较为方便。在此状态下，旋转执行器2只需旋转二分之一(发光单元11位于两条半径上)或者三分之一(发光单元11位于三条半径上)圈就能够使得发光单元11覆盖整个旋转圆，旋转执行器2旋转一周可使得发光单元11在同一 个圆周上扫描三次，车辆照明装置的亮度得到大幅提高，而精度或者分辨率不变。
在本发明的车辆照明装置的一些实施例中，如图1、图2所示，本发明的车辆照明装置还设置有透镜5，透镜5用于将光源1所发出的光线投射出去，形成特定的光形。透镜5的使用，能够使得本发明的车辆照明装置所形成的光形投射距离更远。通常将光源1设置在透镜5的焦点位置附近，以形成更加清晰的投射光形。透镜可以采用玻璃、塑料、橡胶等材质的透镜；可以采用如图1、图2中所示的平凸透镜，也可以采用双凸透镜，或者采用由几个透镜组合而成的透镜组。通常透镜5的光轴平行于旋转执行器2的旋转轴。优选为透镜5的光轴与旋转执行器2的旋转轴在同一条直线上。透镜5的光轴与旋转执行器2的旋转轴在同一条直线上时，光源1发出的光线投射在透镜的正前方，且光形的变形较小。透镜5的光轴与旋转执行器2的旋转轴平行但有所偏差是为了调整光形位置以及各部分光形之间的衔接。二者之间的偏差不会太大，一般为毫米级的偏差。基于透镜的成像原理，在使用透镜5时，在路面上投射的光形与光源1所发出的光形相反，控制器控制发光单元11亮灭的程序需要重新编制。
在本发明的车辆照明装置的一些实施例中，如图7至图12所示，配光元件3为设置在发光单元11两侧区域的反光板31。反光板31设置在发光单元11的两侧，以将发光单元11所发出的光线限定在一定的范围内。如图10、图12所示，发光单元11所发出的大角度散射光线照射在反光板31上，经反光板31的反射而射向发光单元11的前方，从而将发光单元11所发出的光线汇聚在发光单元11前方的一定范围内，减少发光单元11光线的散射，提高车灯照明装置的光形亮度和显示精度。反光板31可以设置在光源1上，也可以设置在用于安装光源1的安装板4上。可以在每个发光单元11的两侧设置一组反光板31，也可以在多个发光单元11的两侧设置一组反光板31。
在本发明的车辆照明装置的一些实施例中，如图7至图10所示，反光板31的反光面为曲面。曲面的反光面能够更好地控制反射光线的反射方向，提高发光单元11所发出的光线的汇聚程度。在本发明的车辆照明装置的另一些实施例中，如图11、图12所示，反光板31的反光面为平面。平面的反光面结构简单，加工方便，也能够实现反射发光单元11所发出的大角度散射光以提高发光单元11所发出的光线的汇聚程度的目的。每个反光板31可以设置在多个发光单元11的一个侧面。在发光单元11进行分组时，可以在每个分组的两侧各设置一个反光板31。在多个发光单元11的侧面设置一组反光板31能够减少反光板31的设置数量，提高车灯照明装置的稳定性。
在本发明的车辆照明装置的一些实施例中，如图13至图24所示，配光元件3为设置在发光单元11出光面区域的聚光件32。聚光件32多为透明材料所制成的透明实体。其可使用透明的塑料、硅胶等材料制成，优选使用PMMA或者PC。聚光件32带有入光面和出光面，其入光面和/或出光面可以为多个，每个入光面和/或出光面可以对应一个或者多个发光单元11。发光单元11所发出的光线从聚光件32的入光面导入聚光件32，经聚光件32的汇聚和调配，从聚光件32的出光面射出，以提高发光单元11所发出的光线的汇聚程度，提高照明的光效和光形的清晰度。
在本发明的车辆照明装置的一些实施例中，如图13至图24所示，每个聚光件32设置在多个发光单元11的出光面区域。可以为车辆照明装置的全部发光单元11设置一块聚光件32，也可以对多个发光单元11进行分组，为每个分组设置一块聚光件32。还可以为每个区域的多个发光单元11设置一块聚光件32。通过为多个发光单元11设置一块聚光件32的方式能够减少车灯照明装置中聚光件32的数量，提高车灯照明装置的稳定性。
作为本发明的车辆照明装置的一种实施方式，如图13至图15所示，聚光件32为截面为等腰梯形的条状透明器件，该透明器件的等腰梯形上底所在的一面为聚光件32的入光面。聚光件32的入光面可以贴近发光单元 11的出光面设置，以便将发光单元11所发出的光线更多地导入聚光件32。等腰梯形下底所在的一面为聚光件32的出光面。发光单元11所发出的光线经该透明器件的折射、该透明器件的等腰梯形的两个腰所在的两个侧面的反射，形成汇聚度较高的光线从聚光件32的出光面射出。
作为本发明的车辆照明装置的一种实施方式，如图16至图18所示，聚光件32为一面为圆柱面的长方体透明器件。此时的聚光件32就相当于一个长的柱面平凸透镜。柱面平凸透镜具有与圆柱面的长轴相平行的轴向子午线和与圆柱面的长轴相垂直的屈光力子午线。聚光件32的圆柱面为聚光件32的出光面，与圆柱面相对的一面为聚光件32的入光面。聚光件32的设置位置使得聚光件32的轴向子午线与发光单元11的排列方向一致且发光单元11位于柱面平凸透镜的焦线附近。发光单元11所发出的光线在通过该聚光件32时，在柱面平凸透镜的屈光力子午线方向发生汇聚，而在轴向子午线方向上不发生聚散度的改变。这就提高了发光单元11所发出的光线的汇聚度，提高了车灯照明装置所形成的光形的清晰度和光效。
作为本发明的车辆照明装置的一种实施方式，如图19至图21所示，聚光件32为多个一体成型的平凸透镜，多个所述平凸透镜的平面朝向同一方向，而形成所述聚光件的入光面，多个所述平凸透镜的凸面形成所述聚光件的出光面。平凸透镜的数目与发光单元11的数目相同。多个平凸透镜的排列方向与发光单元11的排列方向一致，且各个发光单元11分别位于对应的平凸透镜的焦点附近。发光单元11所发出的光线通过相应的平凸透镜时，在各个方向上的光线均发生汇聚，形成大致平行的出射光线，使得车灯照明装置所形成的光形的清晰度和亮度大幅提高。
作为本发明的车辆照明装置的一种实施方式，如图22至图24所示，聚光件32为多个一体成型的聚光器。聚光器的结构可以与现有的车灯中通常使用的聚光器的结构相同。聚光器的数目与发光单元11的数目相同，且多个聚光器的排列方向与发光单元11的排列方向一致。多个发光单元11分别设置在对应的聚光器的入光面处，多个聚光器的出光面可以形成同一个光滑面。该光滑面可以是平面，也可以是曲面。各个发光单元11发出的光线经相应聚光器的调配和传递，形成汇聚度更高的光线，从聚光器的出光面射出。有效提高了车灯照明装置所形成的光形的清晰度和照明亮度。
本发明的车辆照明装置在车灯中的一种设置形式如图25所示，车辆照明装置通过支架6安装在车灯的壳体中，光源1在旋转执行器2的驱动下在车灯壳体中按一定的方向旋转。控制器(图中未示出)根据旋转执行器2的旋转方向和转速控制各发光单元11在各个不同时刻的亮灭。当各个发光单元11在旋转圆的相同位置保持相同的亮灭状态时，本发明的车辆照明装置能够形成固定图案的光形；当各个发光单元11在旋转圆的相同位置的亮灭状态按一定的规律缓慢变化时，本发明的车辆照明装置能够形成动画图案的光形。在发光单元11发出不同颜色的光线时，可以形成彩色图案的光形。在使用透镜5时还可以实现本发明的车辆照明装置所形成的光形相对较远距离的投射。本发明的车辆照明装置可以用车辆行驶在道路上的照明工具和发出各种车辆行驶信号的提示工具。具体地，不仅可作为近光或远光的强照明灯，还可以作为尾灯等信号灯，以及各种动画型或这投射型交互式灯具。
本发明的车辆不可见光投射装置的一个实施例如图26、图27所示，包括光源1、旋转执行器2和控制器。光源1上设置有不可见光发光元件12，不可见光发光元件12可以是红外LED，也可以是红外激光二极管，或者是雷达发射器。旋转执行器2可以安装在支架6上，并通过支架6安装在车灯的壳体上。如图28所示，旋转执行器2是一种旋转装置，其可选用能够高速旋转并能够反馈旋转状态的旋转驱动器件，如带有转速反馈电极的直流电机；也可以使用伺服电机等转速可精确控制的旋转驱动器件。光源1安装在旋转执行器2的旋转轴上，在旋转执行器2旋转时，能够带动光源1跟随旋转执行器2的旋转轴旋转。控制器与旋转执行器2电连接，能够控制 旋转执行器2的旋转速度，也可以接收旋转执行器2反馈的转速信息和旋转位置信息。控制器同时还与不可见光发光元件12电连接，并能够根据旋转执行器2的转速信息和旋转位置信息分别控制各个不可见光发光元件12在不同时间的发光和停止发光，以形成各个不可见光发光元件12在不同旋转位置的发光状态。各不可见光发光元件12在不同旋转位置发出的不可见光照射在一定的时间内叠加形成了具有一定分布图案的不可见光的光分布。如各个不可见光发光元件12在一定时间内在旋转的相同位置的发光状态相同，其所发出的不可见光照射能够形成在一段时间内固定的具有特定分布图案的不可见光光分布。变换各个不可见光发光元件12在特定旋转位置的发光状态，即可变换所形成的不可见光光分布的分布图案。旋转执行器2可以按逆时针方向旋转，也可以按顺时针方向旋转，光源1也跟随着旋转执行器2同向旋转。光源1的供电方式可以采用现有的可在旋转状态下供电器件，如采用导电滑环来向光源1供电。控制器4可使用在当前广泛使用的51系列单片机，在本实施例中使用MCS-51单片机，其控制和编程方法已为相关领域的技术人员所熟知，且本发明并未在此方面做出改进，故而在此不做详细叙述。
在本发明的车辆不可见光投射装置的一些实施例中，如图26、图27所示，在旋转执行器2的旋转轴上安装有安装板4，光源1设置在安装板4上。安装板4能够为光源1提供更高的安装强度，能够防止光源1在高速旋转过程中产生颤动，影响不可见光照射的稳定性。
在本发明的车辆不可见光投射装置的一些实施例中，如图26、图27所示，光源1上设置有多个不可见光发光元件12，多个不可见光发光元件12位于旋转执行器2的不同的旋转半径上。本发明对多个不可见光发光元件12的具体排列方式不做限制，其可以以各种可能的方式排列。多个不可见光发光元件12可以如图28所示呈一条直线状排列在旋转执行器2的旋转轴一侧，可以如图29所示排列在一条通过旋转执行器2旋转轴的直线上，还可以如图30所示排列在旋转执行器2的旋转平面上均匀分布的多条半径上，或者如图31所示排列在旋转执行器2的旋转平面上均匀分布的多条直径上。在使用安装板4时，安装板4也可以根据不可见光发光元件12的不同排列方式设计成不同的形状，如直线形、分叉形或圆形。
在本发明的车辆不可见光投射装置的一些实施例中，如图26、图27所示，光源1还包括发光单元11。控制器同时还与发光单元11电连接，并能够分别控制各个发光单元11的发光状态。控制器能够根据旋转执行器2反馈的转速信息和旋转位置信息分别控制各个发光单元11在不同时间的发光和熄灭，以形成各个发光单元11在不同旋转位置的发光状态。在不同的时间发光单元11在不同旋转位置发出的光线能够形成不同的照明区，在视觉暂留原理的作用下，不同的照明区组合形成特定的可见光光分布图案，以适应车辆在不同行驶环境下的照明要求。此处的照明区是指某一时间段在发光单元11的照射下能够照亮的区域。如图36所示，发光单元11所发出的光线所形成的照射范围为可见光照射区域M，可见光照射区域M包括发光单元11在不同旋转位置(也就是不同的时间段)所发出的光线形成的照明区M1-M12，各个照明区M1-M12均能够独立的控制其亮暗。在照明区M1-M12全亮时所形成的可见光光分布即为可见光照射区域M，照明区M1-M12的不同亮暗组合形成不同的可见光光分布。
在本发明的车辆不可见光投射装置的一些实施例中，本发明的车辆不可见光投射装置上的不可见光发光元件12所发出的不可见光能够形成的照射范围至少能够覆盖发光单元11所发出的可见光能够形成的照射范围。这样，在因应道路行驶环境的需要，无论在可见光的照射范围内的什么区域形成部分照明暗区时，本发明的车辆不可见光投射装置都能够发出不可见光，在该照明暗区内形成不可见光照射，以能够监控该照明暗区内可能影响行驶安全的情况，提高车辆行驶的安全性。如图38所示，在发光单元11形成的可见光照射区域M内的一些照明区(如图38中的M4、M10)内出现其他道路使用者时，为防止灯光造成其他道路使用者炫目，需要控制特定的 发光单元11在特定的旋转位置熄灭，在该照明区(如图38中的M4、M10)形成照明暗区。而照明暗区的存在也会影响车辆驾驶人的观察范围，形成安全隐患，因而需要通过不可见光发光元件12对该照明区范围形成不可见光照射，以能够使用检测器件监控该照明暗区的安全状态，提高驾驶的安全性。
在本发明的车辆不可见光投射装置的一些实施例中，如图37所示，本发明的不可见光投射装置中的发光单元11所发出的可见光形成了可见光照射区域M，其中的不可见光发光元件12所发出的不可见光能够在可见光照射区域M的前方形成不可见光单独照射区N1，能够在可见光照射区域M的左右两侧分别形成不可见光单独照射区N2和N3。通过不可见光单独照射区N1，能够使用检测器件检测到车辆前方更远距离的道路状况，发现驾驶人不能观察到的更远距离的道路上的情况，又不会影响对向车辆的行驶安全。通过不可见光单独照射区N2和N3，能够使用检测器件检测到车辆左右更大范围的情况，拓展车辆驾驶人能够观察到的范围，提高车辆行驶的安全性。特别是车辆夜晚行驶，车辆驾驶人的视野范围受限时，使用效果尤为明显。
在本发明的车辆不可见光投射装置的一些实施例中，如图26、图27所示，在车辆不可见光投射装置的出光光路上设置有透镜5。不可见光发光元件12所发出的不可见光经过透镜5的汇聚而投射出去，形成不可见光光分布图案。发光单元11所发出的光线也可以经透镜5的汇聚而投射出去，形成更为清晰的可见光分布光形。经过透镜5的汇聚，也能够将不可见光光分布图案和可见光分布光形投射得更远。
在本发明的车辆不可见光投射装置的一些实施例中，如图26至图35所示，不可见光发光元件12和/或发光单元11带有配光元件3。如图33、图34所示，配光元件3可以为设置在不可见光发光元件12和/或发光单元11两侧的反光板。如图35所示，反光板能够对不可见光发光元件12和/或发光单元11发出的大角度散射光线形成反射，使得其发出的光线更多地射向光源1前方，提高所发出的光线的汇聚度，并能够增加所形成的光分布的照度。当然，配光元件3也可以是设置在光源1的合适位置的其他能够改变光线传播方向并改变光线分布的光学元件。如，设置在不可见光发光元件12和/或发光单元11前方的聚光器件，具体可以是聚光器，也可以是具有较大入光面的汇聚透镜等等。聚光器件的使用也能够对不可见光发光元件12和/或发光单元11发出的光线进行汇聚，提高所发出的光线的汇聚度，并增加所形成的光分布的照度。
本发明的目标物检测装置包括不可见光检测器件，该不可见光检测器件能够检测本发明任一实施例的不可见光投射装置所形成的不可见光照射范围内的目标物。目标物是指处于道路上的物体和行人等，其中，物体包括跌落的物体、车辆等。该目标物检测装置可以用一个不可见光检测器件检测整个不可见光照射范围内的目标物，也可以用几个不可见光检测器件分别检测不可见光照射范围内不同部分的目标物，几个不可见光检测器件的检测范围覆盖整个不可见光照射范围。在不可见光投射装置所使用的不可见光发光元件12发出的不可见光为红外光时，目标物检测装置的不可见光检测器件可以使用红外接收二极管等红外传感器，也可以使用红外摄像机。在不可见光投射装置所使用的不可见光发光元件12为雷达发射器时，目标物检测装置的不可见光检测器件使用雷达接收器。目标物检测装置可以将不可见光检测器件检测到的目标物信号形成图文信号供驾驶人识别，也可以转换为控制器能够识别的电信号，由控制器进行识别和处理。
在本发明的目标物检测装置的一些实施例中，目标物检测装置还包括可见光检测器件，该可见光检测器件能够检测本发明的不可见光投射装置任一实施例中的发光单元11所投射形成的可见光照射范围内的目标物。其可以使用光敏检测头，也可以使用摄像机。当然该可见光检测器件也可以采用车辆现有的监测设备。上述目标物检测装置可独立设置在车辆上，也可集成在上述车辆不可见光投射装置上。
本发明的不可见光投射装置和相应的本发明的目标物检测装置可以配合使用在智能驾驶汽车上。不可见光投射装置可以不带有独立的控制器，通过智能驾驶汽车上的智能控制装置对不可见光投射装置的光源1和旋转执 行器2进行协调和控制，并可以使用该智能控制装置对目标物检测装置检测到的信息进行分析和处理。不可见光投射装置也可以带有独立的控制器，如图39所示，目标物检测装置检测到的信息传递该控制器，由控制器分析目标物对车辆行驶安全的影响，并控制不可见光发光元件12、发光单元11和旋转执行器2协调工作，形成相应的不可见光的光分布和可见光的光分布，以保障车辆行驶安全和目标物的安全。控制器还可以与智能驾驶汽车上的智能控制装置相连接，必要时还可以通过智能驾驶汽车上的智能控制装置对智能驾驶汽车的行驶状态进行调整和控制，以实现汽车的智能控制，并提高智能驾驶汽车的安全性能。
本发明的不可见光投射装置和相应的本发明的目标物检测装置使用在智能驾驶汽车上时的一种控制过程如图40所示：在汽车的行驶过程中，可见光检测器件持续对道路上的目标物进行检测，在检测到道路上存在其他道路使用者时，控制器根据旋转执行器2的转速，控制发光单元11在不同旋转位置的发光状态，使其他道路使用者所在的可见光照射区域对应的旋转位置的发光单元11熄灭，以使可见光照射范围内的其他道路使用者所在位置形成照明暗区，防止可见光的照射影响其他道路使用者的视线，引起其他道路使用者的不适并影响交通安全。如图38所示，在可见光照射区域M内的照明区M4出现对向车辆时，控制发光单元11在特定旋转位置的发光状态，在照明区M4形成照明暗区。在可见光照射区域M的照明区M10内出现行人时，控制发光单元11在特定旋转位置的发光状态，在照明区M10形成照明暗区。同时，控制器控制不可见光发光元件12在相应旋转位置的发光状态，在照明区M4和/或照明区M10(照明暗区)内形成不可见光照射(图中所示虚框部分即被不可见光所照射)，并通过不可见光检测器件检测其他道路使用者或其他目标物的位置等信息。在其他道路使用者或其他目标物距离汽车的距离大于安全距离S1时，继续对该道路使用者的位置等进行检测，并根据新的检测信息调整可见光照明暗区和不可见光照射的位置，以保持该道路使用者或其他目标物位于可见光照明暗区和不可见光照射范围内。在该道路使用者或其他目标物距离汽车的距离在安全距离S1以内时，控制器控制发光单元11的发光状态，照亮该道路使用者或其他目标物，以引起汽车驾驶人的注意。同时，还可以控制汽车进行减速，并且，在道路交通情况允许的情况下还可以控制汽车调整行驶方向进行避让。这些措施提高了汽车行驶的安全性和汽车的智能驾驶水平。安全距离S1可以根据不同的车速设置不同的值。
通过上述技术方案，本发明的车辆照明装置，采用了含有少量发光单元11的光源1在旋转执行器2的驱动下旋转，并通过控制器控制各个发光单元11在旋转的不同时刻的亮灭状态的方式，利用视觉暂留原理形成不同的光形，结构相对简单，实现较为方便。其使用的发光单元和初级光学元件数量相比于矩阵式大灯和像素化信号灯要少得多的，而实现的功能与矩阵式大灯和/或像素化信号灯的功能相当。配光元件3的使用提高了发光单元11所发出的光线的汇聚度，减少了大角度散射光的浪费和相邻发光单元11之间光线的相互干扰，提高了所形成的光形的亮度和清晰度，在工作过程中每个发光单元11都处于旋转状态，发光单元11发光所产生的热量能够较好地传递到空气中，因而本发明的车辆照明装置散热性能极佳，无需使用附加的散热装置。能够有效地减少车辆照明装置的空间占用和装置的重量。基于上述原因，本发明的车辆照明装置的实现成本较也比较低。
在本发明的车辆照明装置的优选技术方案中，各个发光单元11沿所述旋转轴向旋转圆周在两个以上对称的半径上线性排列，并且每个发光单元11位于不同的旋转半径上的技术方案，能够有效地提高装置的发光精度，能够形成更加细致的照射光形或者显示分辨率。圆形安装板4的使用丰富了光源1的发光单元11的设置方式，增强了光源1的旋转稳定性，并能能够减少旋转阻力。配光元件3设置在多个发光单元11临近区域的设置方式，精简了本发明的车辆照明装置的结构，因而提高了结构的稳定性。不同反光板31或聚光件32的实现形式使用不同的结构实现对发光单元11发出的光线进行汇聚，以提高光源1的光效和投射距离，提高本发明的车辆照明装置所形成的光形的亮度和清晰度。
本发明的车辆不可见光投射装置，使用在旋转执行器2上旋转的不可见光发光元件12发射不可见光，解决了驾驶人不能观察照明暗区以及照明范围以外的区域的难题，大大提高了行车安全。在工作过程中不可见光发光元件12处于旋转状态，不可见光发光元件12发光所产生的热量能够较好地传递到空气中，使得本发明的车辆不可见光投射装置的散热性能极佳，无需使用附加的散热装置即可实现不可见光发光元件12的散热。因此，本发明的不可见光投射装置的重量和实现成本均比较低。
在本发明的车辆不可见光投射装置优选技术方案中，多个不同旋转半径上的不可见光发光元件12的使用，每一个时刻每个不可见光发光元件12均构成旋转平面内的一个不同的像素，提高了不可见光的投射范围和不可见光光分布的分辨率。控制器的使用，能够对旋转执行器2的转速、不可见光发光元件12的发光状态进行控制，形成具有一定分布图案的不可见光分布，以实现对部分区域的不可见光照射，还可以在不可见光发光元件12功率一定的情况下实现局部区域的高强度照射，以提高对目标物的检测精度。发光单元11的设置可以在形成不可见光照射区域的同时形成可见光分布光形，实现车辆的可见光照明。并能够通过不可见光发光元件12和发光单元11的位置设置及控制器的控制，实现符合设计要求的不可见光分布和可见光分布的配合。透镜5和配光元件3的使用提高了不可见光和可见光的投射距离和投射精度。
本发明的目标物检测装置能够对本发明的不可见光投射装置所形成的整个不可见光照射范围内的目标物进行检测，以感知不可见光照射范围内的道路状态，因而能够与本发明的不可见光投射装置相配合提高车辆的安全行驶性能。并具有本发明的不可见光投射装置的优点。
