Abstract

本实用新型公开了一种LED路灯配光透镜，包括整体呈花生壳状透镜本体，所述透镜本体两端设有固定脚，透镜本体底部设有LED安装穴，透镜本体的出光面设有凹穴，所述的安装穴顶部的透镜本体进光面为平面，所述凹穴底面为平面，侧面为曲面。它主要用于路灯照明，灯体正下方的光照强度大，对于光反射较差的路面，在灯体下方也不会产生暗区，适应性强，沿路照区视觉均匀，有利于交通安全。

Description

LED路灯配光透镜
技术领域
本实用新型属于LED照明技术领域，具体是涉及一种LED路灯用二次配光透镜。
背景技术
LED具有省电、显色指数高、寿命长等系列优点，正逐步取代传统的高压钠灯等光源，在路灯照明中得到了广泛应用。LED路灯一般是利用透镜进行二次配光，在灯体下部的路面上形成矩形光斑，从而使光线集中照射在路面上，提高光源的利用率。现有使用的配光透镜，其出光面设有曲面凹穴，这种配光透镜在路面上能形成较好的矩形射面，照度均匀性也较好，但灯体正下方照度相对较低，对于光反射较差的路面，在路灯正下方的路面感觉较暗，以至于沿道路方向会感觉有明暗相间的问题，不利于交通安全。
发明内容
本实用新型要解决的技术问题是提供一种能提高灯下照度，适应性强的LED路灯透镜。
为解决上述技术问题，本实用新型包括整体呈花生壳状透镜本体，所述透镜本体两端设有固定脚，透镜本体底部设有LED安装穴，透镜本体的出光面设有凹穴，其结构特点是所述的安装穴顶部的透镜本体进光面为平面，所述凹穴底面为平面，侧面为曲面。
优选的是所述凹穴的底平面呈椭圆形，其长轴为1至2毫米，其短轴为0.5至1毫米。
由于本实用新型安装穴顶部的进光面为平面，出光面上设有平底凹穴，灯体正下方的光照强度大，对于光反射较差的路面，在灯体下方也不会产生暗区，适应性强，沿路照区视觉均匀，有利于交通安全。
附图说明
下面结合附图和实施例对本实用新型作进一步描述：
图1是本实用新型的剖视图；
图2是图1俯视的结构示意图；
图3是本实用新型配光示意图。
具体实施方式
参照附图，该LED路灯配光透镜包括整体呈花生壳状透镜本体1，透镜本体1两端设有固定脚4，透镜本体1底部设有LED安装穴2，透镜本体1的出光面设有凹穴3，该凹穴3底面为平面，且凹穴3的底平面呈椭圆形，其长轴为1至2毫米，其短轴为0.5至1毫米，凹穴3的侧面为曲面，位于安装穴2顶部的透镜本体1进光面为平面。
