一种基于LED的光束整形透镜
摘要：
本发明公开了一种基于LED的光束整形透镜，其特征在于：它由LED光源1、LED光束入射面2、LED光束出射面3，以及LED左右侧向光束操控面4，及LED前后侧向光束操控面5组成。LED发出的光束一部分通过光束入射面2和光束出射面3进行调控，LED发出的另一部分光束则主要通过侧向光束全反射操控面4，及侧向光束全反射操控面5进行调控。该微结构主要用于产生矩形光斑分布图案。
摘要（英）：

The invention discloses a light beam shaping lens based on an LED. The light beam shaping lens is characterized by comprising an LED light source 1, an LED light beam incident plane 2, an LED light beam emergent plane 3, an LED lateral sideway light beam control plane 4, and an LED longitudinal sideway light beam control plane 5, wherein one part of the light beam sent by the LED is adjusted through the light beam incident plane 2 and the light beam emergent plane 3; the other part of the light beam sent by the LED is primarily controlled by the sideway light beam total reflection control plane 4 and the sideway light beam total reflection control plane 5. The micro-structure provided by the invention is mainly applied to the generation of a pattern with distributed rectangular light spots.
