一种照明透镜
By designing an illumination lens that includes a lens body, the problem of a single light source being unable to illuminate multiple areas is solved by utilizing the principles of total internal reflection and convergence. This achieves a simplified installation and cost-effective uniform lighting effect for clothing display cases.

Abstract
本发明提供了一种照明透镜,将经过透镜本体的光线分别出射到第一照射区域和第二照射区域,透镜本体中,第一光学部设置在主光轴对应第一照射区域的一侧,包括第一全反射面,适于将进入第一光学部的光线全反射后出射到第一照射区域的近光轴侧;第二光学部设置为与第一光学部邻接,包括第二全反射面,适于将进入第二光学部的光线全反射后出射到第一照射区域的远光轴侧;第三光学部,设置为与第二光学部邻接在相对于第一光学部的另一侧,适于将进入第三照射部的光线经过会聚出射到第二照射面。本发明的照明透镜将光源的光线向不同角度进行会聚,实现了远近不同照射面的分别照明效果,具有简化安装和降低成本的效果。
