背景技术
现有技术中存在一种透镜，该透镜包括透镜本体，透镜本体的两个端面分别为入射面和出射面，透镜本体的侧面为反射面。出射面的中部设有复眼透镜阵列。当该透镜用于LED灯具时，LED光源的部分光线经入射面进入透镜本体后从出射面出射，另一部分光线经入射面进入透镜本体，再经反射面反射后从出射面出射。通过在出射面中心设置复眼透镜阵列，可以使光线更加均匀。但由于复眼透镜阵列跟透镜本体加工成一体，无法通过改变复眼透镜的参数来改变光的出射角度，功能较为单一。

例如，当所述反射部3的角度为11°时，即当所述LED光源2的光线经过所述反射部3后光束的光束角为11°时，所述灯具光束的光束角与所述复眼透镜单元51的弦高、半径的关系如下表：
