Abstract

一种采用自由曲面透镜二次光学配光的LED路灯光源，包括LED光源和自由曲面透镜，LED光源是经斜射矩形透镜封装的LED发光体；自由曲面透镜是外表面呈水平轴对称的异形曲面光学元件；LED光源固装在自由曲面透镜底部的中心点。由于采用上述结构，LED光源是经斜射矩形透镜封装的LED发光体，使得LED芯片的光输出方向发生可控的改变；采用自由曲面透镜进行二次光学配光，使得LED路灯光源的光强输出在沿着道路方向产生120度的均匀分布配光，满足道路长度方向上的照明要求，在垂直于道路方向产生60度的均匀分布配光，从而得到具有矩形光照效果的“蝙蝠翼”形配光。

Description

采用自由曲面透镜二次光学配光的LED路灯光源
技术领域
本实用新型涉及LED路灯光源，尤其是一种采用自由曲面透镜二次光学配光的LED路灯光源。
背景技术
路灯是城市照明的重要组成部分，传统的路灯通常采用整体光效低的高压钠灯，造成巨大的能源浪费。作为高压钠灯替代品的LED路灯凭借高光效、长寿命、易安装等特点备受青睐。然而，LED路灯光源的照射比较集中，均匀度较差，使得LED路灯光源的光输出在路面上形成一个圆形光斑，造成在道路方向上的照明角度有限，圆形光斑之间由于没有光的平滑叠加过渡而形成明显的暗区，产生斑马效应；同时，在道路垂直方向上散落在道路边外而没有被利用的光较多，无法满足道路照明对路灯光输出特性的要求。
发明内容
针对目前LED路灯光源的不足之处，本实用新型的目的是提供一种采用自由曲面透镜二次光学配光的LED路灯光源，使其满足道路照明中对路面照度的要求，即LED路灯光源的光强输出曲线沿着道路方向是“蝙蝠翼”形，在垂直于道路方向上绝大部分的光分布在路面上而非道路边外。
为达到上述目的，本实用新型所采取的技术方案是：一种采用自由曲面透镜二次光学配光的LED路灯光源，包括LED光源和自由曲面透镜，LED光源是经斜射矩形透镜封装的LED发光体；自由曲面透镜是外表面呈水平轴对称的异形曲面光学元件；LED光源固装在自由曲面透镜底部的中心点。
本实用新型的有益效果是：由于采用上述结构，LED光源是经斜射矩形透镜封装的LED发光体，使得LED芯片的光输出方向发生可控的改变；采用自由曲面透镜进行二次光学配光，使得LED路灯光源的光强输出在沿着道路方向产生120度的均匀分布配光，满足道路长度方向上的照明要求，在垂直于道路方向产生60度的均匀分布配光，从而得到具有矩形光照效果的“蝙蝠翼”形配光。本实用新型设计新颖，结构合理，能够满足道路照明中对路面照度的要求，具有广泛的市场前景和推广价值。
附图说明
附图1是本实用新型的主视图；
附图2是本实用新型的左视图；
图中各标号分别是：(1)LED光源，(2)自由曲面透镜。
具体实施方式
下面结合附图对本实用新型作进一步的详细说明：
参看附图，本实用新型一种采用自由曲面透镜二次光学配光的LED路灯光源，包括LED光源1和自由曲面透镜2，LED光源1是经斜射矩形透镜封装的LED发光体；自由曲面透镜2是外表面呈水平轴对称的异形曲面光学元件；LED光源1固装在自由曲面透镜2底部的中心点。
以上所述，仅是本实用新型一种较佳实施例而已，并非对本实用新型的技术范围作任何限制，凡是依据本实用新型的技术实质对上面实施例所作的任何细微修改、等同变化与修饰，均仍属于本实用新型技术的范围内。
