Technical Problem

但目前市场上关于此类场景的产品选择较少,少量可用产品多为道路路灯或庭院灯的替代方案,这些替代产品存在的主要缺陷为发光亮度不均匀和亮度过高,易形成强烈的明暗反差以及用电浪费,无法满足小路灯应用场景对均匀照明的基础需求,进而影响场景安全性与美观性

Benefits of technology

本方案通过将透镜本体中的第一凹槽的槽底设计成曲面,这样能够对LED光源发出的光线进行选择性收集:一方面,能精准聚拢LED光源的中心有效光线,确保光线集中用于目标照明区域,减少因光线分散造成的无效能耗;另一方面,可通过曲面曲率的合理设计,避免对中心强光的过度汇聚,使初始入射光的光强分布更平缓,从源头降低亮度过高的风险,间接减少用电浪费;通过将偏光部的出光面设计成多个不同曲率的曲面,能够实现分段式光线角度调控,不同曲率的曲面可针对经过第一凹槽初步处理后的光线,进行差异化折射,例如,曲率较小的曲面可引导部分光线向较远距离的暗区偏折,填补传统产品的照明死角,曲率较大的曲面可适度约束另一部分光线,避免其过度扩散导致近距过亮;本方案通过多曲面的协同作用,光线能按照中低位小路灯的场景需求,均匀覆盖从透镜近处到远处的整个目标区域,有效消除明暗反差,解决亮度不均匀问题。
