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。

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1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划分。
其中，更优选地，n为大于2的正整数，以能更好地调整所述照明装置的出光角度及提高所述照明装置的出光效率。
请参阅图1，一实施例中，可以将所述光源10的出光面101沿水平方向人为划分出4个出光区域102；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，例如二个、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，以达到特殊的出光效果。
在一些实施例中，如图1所述，所述第一反射模块20包括n个第一反射子模块21，n个所述第一反射子模块21与n个所述出光区域102一一对应。每个所述第一反射子模块21用于将对应的所述出光区域102出射的光线反射；每个 所述第一反射子模块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，各个所述第一反射子模块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，各个所述第一反射子模块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。
在一些实施例中，如图1所述，所述第二反射模块40包括n个第二反射子模块41，n个所述第二反射子模块41与n个所述第一反射子模块21一一对应，各所述第二反射子模块41分别设置于对应的所述第一反射子模块21的反射光路上，每个所述第二反射子模块41用于将对应的所述第一反射子模块21出射的光线沿预设方向再次反射。

在一些实施例中，各个所述第二反射子模块41的反射面与所述光源10的出光方向的倾斜夹角均在40度至45度之间，以使出光角度较好，减少进入人眼的眩光。

在一些实施例中，如图1所述，n个所述第一反射子模块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、o为正整数或零，且m+o＝n；也就是说，所述第一反射子模块21可以全部为正向反射子模块211，也可以全部为逆向反射子模块212，还可以部分为正向反射子模块211，部分为逆 向反射子模块212；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102出射的光线沿不同的方向出射，即，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。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，m个所述第二反射子模块41分别设置于对应的正向反射子模块211的反射光路上；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，o个所述第二反射子模块41分别设置于对应的所述逆向反射子模块212的反射光路上。
其中，m可以等于o，即，正向反射子模块211的数量等于逆向发射子模块212的数量，从而使所述照明装置100的出光整体较为均匀；m也可以大于或小于o，即，正向反射子模块211的数量也可以大于或小于逆向发射子模块212的数量，从而使所述照明装置100的不同位置的出光量不同，从而使出光呈现层面变化。
在一些实施例中，当m大于1时，即，所述正向反射子模块211的数量为多个时，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102出射的光线沿一第一方向反射；并且，优选与各所述正向反射子模块211相对应的各所述第二反射子模块41的反射面也大致相平行。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。
