附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根 据这些附图获得其它的附图。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
本申请提供一种多通道出光照明装置，包括：光源，用于将光线准直出射，所述光源的出光面划分有n个出光区域，其中n为大于1的正整数；反射模块，所述反射模块包括n个反射子模块，n个所述反射子模块与n个所述出光区域一一对应，每个所述反射子模块用于将对应的所述出光区域出射的光线反射从而形成多通道出光；每个所述反射子模块的反射面均朝向所述出光面倾斜。
其中，因发散角的存在，光源的出光面向上出射的光线，进入人眼中会形成眩光，故，一般需要将光源发射的光线中向上出射的光线用截光板遮挡，这样才能基本上消除眩光，但是这样这会遮挡住部分非发散的光线，从而使所述光源的光线出射率将非常低；而本申请中，将光源的出光面划分出n个出光区域，对应每个出光区域设置一个反射子模块，每个所述反射子模块的反射面均朝向所述出 光面倾斜，从而能将每个区域的出光高度都降低，这样，就能基本上消除眩光，还能够提高所述光源的出光率。
以下结合图示对本申请的多通道出光照明装置进行说明。
请参阅图1至图6，为本申请第一实施例提供的一种多通道出光照明装置的示意图。所述多通道出光照明装置100包括光源10及形成于光源10的出光侧的反射模块20。
所述光源10用于将光线准直出射；其中，目前的准直技术并不能做到完全准直，故，所述光源10出射的准直光线一般存在一个发散角。
在一些实施例中，所述光源10可以包括发光元件及准直元件等，所述发光元件用于发射出光线，所述准直元件用于将所述发光元件发射出的光线准直；其中，所述发光元件的数量可以为一个或多个，所述准直元件的数量也可以为一个或多个，本申请对此不作限定。所述准直元件可以包括自由曲面透镜、菲涅尔透镜及波纹扩散透镜等，从而使所述光源10具有更好的准直效果。
本申请中，将所述光源10的出光面101人为划分出n个出光区域102，其中n为大于2的正整数。其中，所述n个出光区域的划分可以根据出光的需要任意划分，也可以为沿水平方向或与水平方向垂直的方向等划分。
请参阅图1，一实施例中，将所述光源10的出光面101沿水平方向人为划分出4个出光区域102；请参阅图2至图5，另一实施例中，将所述光源10的出光面101沿水平方向人为划分出6个出光区域102；可以理解，在其他实施例中，还可以将所述光源10的出光面101人为划分出其他数量的出光区域，例如三个、五个、七个等等，并不以本实施例的图示为限。
其中，n个所述出光区域102的出光面积可以相同，以使最终出射的光线较为均匀；n个所述出光区域102的出光面积也可以不相同。
如图1至图5所示，所述反射模块20包括n个反射子模块21，n个所述反射子模块21与n个所述出光区域102一一对应。每个所述反射子模块21用于将对应的所述出光区域102出射的光线反射从而形成多通道出光；每个所述反射子模块21的反射面均朝向所述出光面101倾斜，从而使反射面的出光朝向所述出光面101倾斜，进而压低所述照明装置整体的出光高度，减少眩光。
在一些实施例中，各个所述反射子模块21的反射面与所述出光面101的倾 斜夹角均在40度至45度之间，以使出光角度较好，减少进入人眼的眩光。
在一些优选实施例中，各个所述反射子模块21的反射面与所述出光面101的倾斜夹角均在42度至45度之间，以使出光角度更好，减少进入人眼的眩光。其中，如图2至图5所示，n个所述反射子模块21中可以包括m个正向反射子模块211及o个逆向发射子模块212，m也为正整数且m小于或等于n，o为正整数或零，且m+o＝n；也就是说，所述反射子模块21可以全部为正向反射子模块211，也可以部分为正向反射子模块211，部分为逆向反射子模块212。正向指的是与本申请的多通道出光照明装置的较主要且必要的出光方向大致一致的方向，也就是说，正向反射子模块211出射的光线对应的是所述多通道出光照明装置的主出光光线，或者说所述正向反射子模块211用于将对应的所述出光区域102出射的光线沿所述多通道出光照明装置100的主出光方向反射。
其中，m个所述正向反射子模块211与n个所述出光区域102中的m个所述出光区域102一一对应，o个所述逆向反射子模块212与n个所述出光区域102中的o个所述出光区域102一一对应；所述正向反射子模块211及所述逆向发射子模块212用于将对应的所述出光区域出射的光线沿不同的方向出射；或者说，所述正向反射子模块211反射后的光线的出光方向与所述逆向发射子模块212反射后的光线的出光方向不同。
优选地，m大于或等于o，以使更多的光线自所述多通道出光照明装置100的主出光方向出射。
当m大于1时，优选各所述正向反射子模块211的反射面大致相平行，从而，每个所述正向反射子模块211均用于将对应的所述出光区域出射的光线沿一第一方向反射。其中，本申请中的大致相平行可以为平行或者有5度以下的夹角；本申请中的大致相平行也可以为平行或者有3度以下的夹角；下同。
在一些实施例中，请参阅图1至图5，在沿所述光源10的出光方向上，m个所述正向反射子模块211的反射面相错开，在沿与所述光源10的出光方向垂直的方向上，m个所述正向反射子模块211的反射面顺次无交叠分布；也就是说，无论是在沿所述光源10的出光方向上，还是在沿与所述光源10的出光方向垂直的方向上，m个所述正向反射子模块211的反射面在的垂直投影除端点外均无交叠。
在一些实施例中，在沿所述光源10的出光方向上，m个所述正向反射子模块212的反射面还相错开一段距离。
当o大于1时，优选各所述逆向反射子模块212的反射面也大致相平行，每个所述逆向反射子模块212均用于将对应的所述出光区域102出射的光线沿一第二方向反射；所述第一方向与所述第二方向为两个不同的方向。
在一些实施例中，请参阅图1至图4，在沿所述光源10的出光方向上，o个所述逆向反射子模块212相错开，在沿与所述光源10的出光方向垂直的方向上，o个所述逆向反射子模块212顺次无交叠分布。在一些实施例中，各个所述反射子模块21的反射面与所述出光面101的倾斜夹角均相等或大致相等；也就是说，如果n个所述反射子模块21部分为正向反射子模块211部分为逆向反射子模块212，则所述正向反射子模块211反射后的光线的出光方向与所述光源10的出光面101的夹角与所述逆向发射子模块212反射后的光线的出光方向与所述光源10的出光面101的夹角相等或大致相等。

请参阅图5，为当出光区域102的数量为6个时的再一种实施例，其中，所述正向反射子模块211的数量为六个，即不设置逆向发射子模块212；六个所述正向反射子模块211与六个所述出光区域102一一对应。
当然，在其他实施例中，所述正向反射子模块211与所述逆向反射子模块212也可以采用其他数量分布，并不以上述实施例为限。
可以理解，在其他实施例中，当所述出光区域102的数量为6个以外时，所述正向反射子模块211与所述逆向反射子模块212的设置方式可以参照上述进行设置，此处不再一一列举。
在一些实施例中，如图6所述，所述多通道出光照明装置100还包括截光板30，所述截光板30设置于所述反射模块20的反射光路上，所述截光板30用于阻挡所述反射模块20出射的部分光线，或者说，所述截光板30用于阻挡所述反射模块20出射的光线中产生眩光的部分光线；本申请中，所述多通道出光照明 装置100用于照明时，所述截光板30用于阻挡水平向上出射的大部分光线，也即产生眩光的主要光线。
所述多通道出光照明装置100可以用作汽车的近光灯。
如图7所示，本申请第二实施例还提供一种汽车车灯200，所述汽车车灯200包括如第一实施例所述的多通道出光照明装置100。
其中，所述多通道出光装置100可以为所述汽车的近光灯，所述光源的出光面101可以与所述汽车的水平方向相一致，所述反射模块20均朝向地面倾斜设置。

可以理解，所述汽车车灯200可以采用铝或者不锈钢制作，以具有更好的机械性能，不易损坏；另外，所述汽车车灯200中的各模块都可以采用IP68等级的防护标准制作，以具有超高的防水性能，从而使所述汽车车灯200可以适用于越野车等涉水车型。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详细描述的部分，可以参见其它实施例的相关描述。
