可选地，所述导光件40还包括反射面43，所述反射面43环设于所述入光面41的周围，第一连线与第二连线之间的第二夹角小于所述第一夹角的2倍，所述第一连线为入光面41的中心入光点与所述反射面43的第一端点之间的连线，所述第二连线为入光面41的中心入光点与所述反射面43的第二端点之间的连线，所述第一端点设置于所述反射面43靠近所述红外发生器30的一侧，所述第二端点设置于所述反射面43远离所述红外发生器30的一侧。

本实施例中，可以将入光面41与所述目标连线L1之间的交点称为入光面41的中心入光点，即图3中的D点，将设置于反射面43靠近红外发生器30的一侧的端点称为第一端点，即图3中的E点，将设置于反射面43远离红外发生器30的一侧的端点称为第二端点，即图3中的F点。
本实施例中，将D点与E点之间的连线称为第一连线，将D点与F点之间的连线称为第二连线。将第一连线与第二连线之间的夹角称为第二夹角，即图3中的α2。
本实施例中，为了保证红外光在导光件40内的传播路径，使得红外光可以传输至出光面42的出光点，对红外光在导光件40内的传播路径进行整形，设置第二夹角小于第一夹角的2倍。
图3示出的仅为一个反射面43对应的第二夹角，应理解，在导光件40包括多个反射面43的情况下，每个反射面43对应的第二夹角均小于第一夹角的2倍。
可选地，所述出光面42包括锯齿结构，所述锯齿结构包括多个第一锯齿面421和多个第二锯齿面422，每个第一锯齿面421和每个第二锯齿面422相邻设置，所述第一锯齿面421的面积大于所述第二锯齿面422的面积，且所述第一锯齿面421与所述出光面42所处平面之间的第三夹角小于所述第一夹角的2倍。

可选地，所述入光面41的中心入光点位于所述出光面42对应的光轴的第一侧；
所述出光面42包括锯齿结构，且所述锯齿结构的尖端朝向所述第一侧。
上述入光面41的中心入光点即位于入光面41中心的入光点；如图3所示，连线AG即出光面42对应的光轴。设置入光面41的中心入光点位于该光轴的第一侧，且锯齿结构的尖端朝向该光轴的第一侧，也就是说，锯齿结构的尖端朝向与入光面41的中心入光点位于出光面42对应的光轴的同一侧。
请参阅图3，在图3示出的导光件中，入光面41的中心入光点位于出光面42对应的光轴的下方，这样，为了使得通过入光面41的中心入光点射入至导光件40内的红外光可以从出光面42的中心出光点对外辐射，设置出光面42的锯齿结构的尖端朝向方向向下，调整红外光的出光方向，使得红外光通过出光面42的中心出光点对外辐射。
应理解，在其他实施例中，若入光面41的中心入光点位于出光面42对应的光轴的上方，则设置锯齿结构的尖端朝向方向向上。
可选地，所述出光面42包括锯齿结构，且相邻锯齿结构的尖端之间的距离为所述透光孔直径的十二分之一至八分之一。
本实施例中，出光面42包括锯齿结构，上述锯齿结构用于偏折红外光。请参阅图4，图4中的d表示相邻锯齿结构的尖端之间的距离，设置相邻锯齿结构的尖端之间的距离相等，且为透光孔直径的十二分之一至八分之一，可选地，设置相邻锯齿结构的尖端之间的距离为透光孔直径的十分之一。
