Abstract

一种LED路灯，包括电源系统、壳体及LED线路板，其特点是壳体内为中空的空腔，空腔的左右两侧开有散热孔，壳体上端设有圆弧鳍片，壳体的下端为均匀排列的安装基座，安装基座的两端设定位孔，LED线路板通过定位孔固定在壳体的安装基座上。本实用新型的LED路灯结构简单、节能环保，在确保空气散热的同时，还充分利用车辆经过时产生的气流进行散热，气流方向与散热鳍片方向一致，加快了空气在散热片上的流动，加速了热量传递，且可防止雨水进入壳体内。

Description

LED路灯
技术领域
  本实用新型涉及一种LED路灯。
背景技术
路灯是城市照明的重要组成部分，其耗电占据整个照明用电的很大部分，新型LED路灯的使用对城市照明节能环保具有十分重要的意义。由于LED本身耐温能力比较差，LED芯片工作环境的温度必须保证≤85℃，但是大功率LED工作时产生的热量非常大，如何解决大功率LED的散热问题成为固态照明领域的热点，LED热积累引发的光衰也成为LED道路照明光源推广使用的瓶颈。
实用新型内容
    本实用新型的目的就是提供一种结构简单、散热效果好、节能环保的LED路灯。
    本实用新型的LED路灯，包括电源系统、壳体及LED线路板，其特点是壳体内为中空的空腔，空腔的左右两侧开有散热孔，壳体上端设有圆弧鳍片，壳体的下端为均匀排列的安装基座，安装基座的两端设有定位孔，LED线路板通过定位孔固定在壳体的安装基座上。
    本实用新型的LED路灯结构简单，为了增大散热面积，加快大功率LED的热量传递，将壳体设计为中空结构，为了增加空气对流，在壳体左右两侧设计空气对流散热孔，同时在壳体上设散热鳍片，这些结构在确保空气散热的同时，还可充分利用车辆经过时产生的气流进行散热，气流方向与散热鳍片方向一致，加快了空气在散热片上的流动，加快了热量传递，且可防止雨水进入壳。
附图说明
    图1为本实用新型结构示意图。
    图2为图1中A—A剖示图。
    图3为图2仰视示意图。
具体实施方式
    实施例如图1-3所示：一种LED路灯，包括电源系统1、壳体2及LED线路板，壳体2内为中空的空腔4，空腔4的左右两侧开有散热孔5，壳体2上端设有圆弧鳍片3，壳体2的下端为均匀排列的安装基座6，安装基座6的两端设有定位孔7，LED线路板通过定位孔7固定在壳体2的安装基座6上。
