 本发明的最佳实施方式
本发明所述的车灯包括左车灯模块和右车灯模块。灯光即为车灯出射的光。
为了使得说明更清楚，更容易理解以下结合附图，对本发明的方案进行详细说明。
本发明的车辆自适应照明装置，包括光源模块、左车灯模块、右车灯模块、雷达和控制部。以下结合图1进行说明。
其中，左车灯模块2位于光源模块1的光路上，右车灯模块3位于光源模块1的光路上。控制部4与光源模块1、左车灯模块2、右车灯模块3以及雷达5电性连接。雷达5用于检测车辆前侧的道路信息，并将道路信息反馈给控制部。控制部4接收雷达的反馈道路信息，控制左车等模块2和右车灯模块3的出射光的照射位置和照射的区域，并控制光源模块1发出的照明光的亮度。
本发明的该技术方案，通过雷达5检测的道路信息，控制部4可以根据道路信息，自适应的调节左车灯模块2、右车灯模块3以及光源模块1，从而根据道路中的不同交通参与者，出射照射区域、亮度不同的光，并使得照射的位置随交通参与者的性质不同而改变。
雷达5可以包括超声波探测模块、红外探测模块、激光探测模块和视频探测模块、远程测温传感器的至少一种。
为了更好的实现交通参与者的监控，使得控制部更加准确控制车灯且使得车灯出射的光更适用不同交通参与者，使得车辆驾驶更加安全。雷达包括超声波探测模块和红外探测模块，该超声波探测模块用于探测车辆前侧道路的交通参与者的位置信息，并将探测信息反馈给控制部，该红外探测模块用于探测车辆前侧道路的交通参与者的类型信息，并将探测信息反馈给控制部。其中，超声波探测模块可以探测到一定距离内的障碍物与车的距离，而红外探测模块可以探测到一定距离内障碍物的性质，以区分不同的交通参与者，以便控制器4可以根据交通参与者的性质和距离发出不同的控制指令。比如：探测到交通参与者是行人时，左车灯向左照射，以绕开行人；探测到交通参与者是车辆时（会车时），左车灯向右照射，以绕开对向来车，以保证对向来车的行驶安全；或者照射到是动物时，灯光减弱，以避免惊吓到动物造成交通事故；或者出射光在某一区域的亮度为零，其他区域高亮显示；或者投射出特定形状或特性图案，实现与交通参与者的信息交互，比如在车辆处于高速行驶状态，检测近距离路边的行人，则在行人附件投射出“Stop”，以示行人停止。
上述方案中，控制部4根据红外探测模块的探测的交通参与者的类型信息，选择左车灯模块和右车灯模块的投影模式。其中，投影模式包括但不限于行人通行模式、行人停止模式、动物通行模式、会车模式、车辆导航模式。其中当检测到交通参与者是行人且车辆处于低速状态，控制部4控制左车灯模块2和右车灯模块3投射出斑马线，示意行人通行，也即行人通行模式；当检测到交通参与者是行人且车辆处于高速状态且距离较近，控制部4控制左车灯模块2和右车灯模块3在行人附近投射出“Stop”或“返回”或车灯闪烁，以示行人车辆暂无法停止，也即行人停止模式；当检测到交通参与者为动物时，控制部4控制车灯的亮度减弱或者动物所在区域的灯光关闭或者控制车灯的出射光的照射区域以绕开该动物，也即动物通行模式；当检测到对向来车，控制部4控制车灯从远光灯切换到近光灯或者减弱左车灯模块的出射光亮度或者调整左车灯模块的出射光的照射位置或者关闭左车灯模块，也即会车模式；当控制部4接收到导航模式时，控制部4采用雷达检测当前道路，并给出行驶相应的标识：直行、左转弯、右转弯、掉头。本技术方案根据交通参与者的不同，采用不同的投影模式，能够更加精细的控制车辆，并且给交通参与者更好的体验。
本发明的光源模块可以为固态光源。当光源模块为固态光源时，固态光源包括激光器阵列或者LED阵列或者激光器与LED阵列的组合，该固态光源可包括一个或多个阵列，该阵列中的每个固态光源可以单独控制也可以整体控制。固态光源包括多个阵列且每个固态光源单独控制时，左车灯模块2和右车灯模块3的结构可以更简单，以左车灯模块为例，如图2所示，左车灯包括光源模块1和左车灯模块2，其中光源模块1包括第一光源阵列01和第二光源阵列02，左车灯模块2包括镜头，光源模块1发出的照明光通过镜头出射。本实施例中，控制器4通过控制固态光源阵列的电流大小或者固态光源中的固态光源开启的数量或开启的固态光源的位置，来达到不同的显示效果。本实施例中的车灯的结构简单，并且成本低。本实施例中，当控制部根据雷达的反馈道路信息，需要某些区域加强显示时，控制部控制需要加强显示的区域对应的光源模块1中的固态光源的电流增大，以实现车灯前方的某些区域加强显示；或者需要某些区域降低光亮度或者无光亮度时，控制部控制需要降低亮度或者无光亮度的区域对应的光源模块1中的固态光源的电流，以实现车灯前方的某些区域无灯光或者弱灯光。
本发明的车灯的光源模块1还可以是固态光源激发波长转换元件。本实施例中结合图3进行说明，以左车灯为例，右车灯参照左车灯模块。其中左车灯包括光源模块1和左车灯模块2。其中光源模块1包括光源11和波长转换元件12，其中，光源11包括固态光源或者一组或多组固态光源阵列，其中固态光源包括但不限于激光、LED。波长转换元件12可以是固定式的或者周期性运动的，当为固定式的波长转换片时，固定式波长转换片可以为发光陶瓷，固定式的波长转换片上设置荧光粉层或者量子点，其中荧光粉层可以为黄色荧光粉层或层叠设置的绿色荧光粉层和红色荧光层或者是红色荧光粉和绿色荧光粉均匀混合形成的红绿荧光粉层，或者是黄色量子点形成的层或者是绿色红色量子点形成的层。本方案的波长转换元件12因无需运动，可靠性更高。当为周期性运动的波长转换元件12，该波长转换元件12可以是线性运动或者绕轴周期性旋转，其中该波长转换元件12上设置有黄色或者红色和绿色的荧光粉或者量子点。该技术方案由于波长转换元件12周期性运动，能够降低波长转换材料的老化或热饱和，同时，也能实现更好的散热。左车灯模块2包括光调制组件21和镜头组件22，光调制组件21包括但不限于相位板、DMD、LCD、LCOS，其中，采用相位板或LCD使得成本更低，其相位板可以相对特定相位的光，控制更加简单，光调制组件21对光源模块1出射的照明光进行调制形成投影光；镜头组件22包括至少一个透镜或透镜组，用于对投影光进行成像，并对投影光进行调整后投影到车前方，其中，图3中投影区域3即是经过光调制组件和镜头组件调整之后的光。其中左车灯模块还包括调光模块，用于对投影光的投射位置进行调整，比如控制器4控制调光模块调整投影光向左或向右或向上或向下以一定的角度投射，该方案可以实现一个左车灯多个功能，从而简化整个车灯的结构，比如该车灯通过调光模块成为远光灯也可成为近光灯也可成为示宽灯等。
本发明的另一实施例，车灯照明装置如图4所示。车辆自适应照明装置包括光源模块1和左车灯模块2和右车灯模块3。其中，光源模块1包括光源11、分光元件13和第一波长转换元件12’和第二波长转换元件12。其中光源11如前实施例所述，第一波长转换元件12’和第二波长转换元件12如前实施例中的波长转换元件，在此不在赘述。本实施例中的分光元件13用于将光源11的光分成两路，一路光沿着第一通道到达第一波长转换元件12’用于激发第一波长转换元件12’上的波长转换材料形成左车灯照明光，另一路光沿着第二通道到达第二波长转换元件12用于激发第二波长转换元件12上的波长转换材料形成右车灯照明光。控制部4通过控制分光元件13的停留位置或者透反比例来控制左车灯的出射光亮度和右车灯的出射光亮度。所述左车灯模块2包括左光调制组件21和左镜头组件22；所述右车灯模块3包括右光调制组件31和右镜头组件32，左镜头组件22位于右光调制组件21的光路上。其中，左光调制组件21位于左车灯照明光的光路上，右光调制组件31位于右车灯照明光的光路上，左镜头组件22位于右光调制组件21的光路上。其中左光调制组件21和右光调制组件21参考前述实施例中的光调制组件，左镜头组件22和右镜头组件32参考前述实施例中的镜头组件，在此不再赘述。本实施例中的光源，从光源11出射的光先经过分光元件13进行分光后再激发波长转元件12’和波长转换元件12，由于光源11是固态光源，出射的光相对比较集中，尤其是激光，从而可以减小分光元件的体积或者减少光路中的收光的光学元件，从而使得结构更简单。
本实施例中，光源模块1的结构也可以如图5所示，光源11出射的光先经过波长转换元件12转换成照明光，再通过分光元件13将照明光分成两路，一路为第一照明光，另一路为第二照明光。本技术方案先经过一个波长转换元件12进行波长转换形成照明光，相对与图4中先分光后激发波长转换元件相比，更加节约波长转换元件12的成本，即采用一个波长转换元件即可实现左车灯和右车灯的照明，从而减小成本。
其中，分光元件13可以为线性运动的板也可以是周期性运动的转轮。结合图6和图7具体说明。如图6所示分光元件13为线性运动的板，所述板包括第一区域131、第二区域132、第三区域133，控制器4根据需要切换分光元件13的不同区域到光路上，实现第一通道和第二通道的光的不同亮度分布。本实施例的分光元件13可以包括一个或多个区域（比如两个、四个、五个、六个区域等），每个分区对光的透射率和反射率不同，仅以三个区域为例，其中，第一区域131、第二区域132、第三区域133对光透射率和反射率不同。优选的实施例，第一区域131反射全部光，第二区域132大致反射50%的光，第三区域133透射全部光。控制器4控制分光元件13的不同区域到光路上，使得左车灯和右车灯出射不同亮度的光。本实施例中的分光元件13结构简单，通过简单的结构结合控制器4即可实现左车灯和右车灯出射光的不同亮度分布。图7给出了分光元件13的另一种结构的实施例，其中，分光元件13为以转轴进行周期性旋转的转轮，转轮的圆周上设置多个分区，每个分区对光的透射率和反射率不同，本方案中，转轮上的分区不限于两个或多个，根据左车灯和右车灯需要的光亮度分布来适当设置分区的数量。优选的实施例，转轮包括五个分区，其中，第一分区131透射大致100%的光，第二分区132透射大致80%的光，第三分区133透射大致50%的光，第四分区134透射大致30%的光，第五分区135透射大致0%的光。各个相邻分区透射的光的比例可以阶梯设置，也可以高低相间的设置方式。本技术方案中，采用分区的转轮作为分光元件13，可以使得转轮的控制更简单，也即转动方向只需要一个方向即可。该分光元件13的运动控制优选为机械运动。
本实施例中，分光元件13也可以是液晶分光元件13，给予不同的电压或电流使得液晶分光元件13对光的透射率和反射率不同。本发明的分光元件13的实现方式包括但不限于上述实施例的三种方式，只要能实现光的透射率和反射率的改变都可以。
本实施例中的分光元件13的分区可以设置不同透射率和反射率的玻璃，所述玻璃通过打磨使得表面的粗糙程度不同可以实现不同的透射率和反射率，由于玻璃的成本低，这使得车灯的成本降低。当然，可以在透光的光学介质上设置光学薄膜，实现不同的透射率和反射率，该透光的光学介质包括但不限于玻璃、塑料等；该光学薄膜采用镀膜工艺，在不同的分区实现不同的透射率和反射率。
本发明提出另一实施例，如图8和图9所示，所述光源模块1包括左光源模块11’和右光源模块11，其中左光源模块11’和右光源模块11。所述左光源模块11’和右光源模块11独立被控制部控制，控制部独立控制左光源模块11’和右光源模块11的电流或电压，实现左光源模块11’和右光源模块11独立脉冲宽度或脉冲幅度调制。控制部独立控制左车灯模块2和右车灯模块3。其中左车灯模块2和右车灯模块3可以如前述示例中的左车灯模块和右车灯模块。
其中左车灯模块和右车灯模块还可包括光路调整部件，如图10所示，光路调整部件23，用于将光调制组件21调制后的光进行光路调整，使得光沿着特定的方向或特定的角度从镜头组件22出射。其中，光路调整部件23设置在光调制组件21和镜头组件22之间，可以切换不同的状态，从而使得如车灯在近光灯和远光灯之间切换，另外，可以使得光照射或不照射某一区域。该光路调整部件23优选为反射元件，通过机械调整光路调整部件23实现将光反射到不同的位置，如图11所示。如图12所示，光路调整组件23直接将光源模块出射的照明光进行光路调整，以使得照明光以特定角度或特定的方向进行出射。
本发明还包括一种车辆自使用照明系统，如图13所示，包括控制部1、左车灯控制单元2、右车灯控制单元3、雷达控制单元4。其中，雷达控制单元4用于分析雷达的检测结果形成交通参与者信息，并将交通参与者信息反馈给所述控制部；控制部1接收交通参与者信息，根据交通参与者信息生成左车灯控制指令和右车灯控制指令； 左车灯控制单元2用于接收左车灯控制指令，调整左车灯出射的光投影模式；右车灯控制单元4用于接收右车灯控制指令，调整右车灯出射的光投影模式。
其中，左车灯控制单元2包括左投影位置控制模块、左亮度控制模块和左光调制模块；右车灯控制单元3包括右投影位置控制模块、右亮度控制模块和右光调制模块。
其中，投影位置控制模块用于控制左车灯的投影位置或投影区域；左亮度控制模块用于调整左车灯的开关及其电流脉冲；左光调制模块用于将左车灯的照明光调制成具有特定光分布的图像光出射；投影位置控制模块用于控制右车灯的投影位置或投影区域；右亮度控制模块用于调整右车灯的开关及其电流脉冲；右光调制模块用于将右车灯的照明光调制成具有特定光分布的图像光出射。
本实施例中的各器件的功能和作用参考前述实施例中的车辆自使用照明装置的作用和连接方式。
另外，本发明的光的传输可以通光光纤传输，例如光源和波长转换元件之间可以采用光纤将光源的光引导到波长转换元件，光源模块和左车灯模块之间可以采用光纤将光源模块的照明光引导到左车灯模块，光源模块和右车灯模块之间可以采用光纤将光源模块的照明光引导到右车灯模块。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或者直接、间接运用在其他相关的技术领域，均视为包括在本发明的专利保护范围内。
