Abstract

一种LED路灯用的导风散热灯罩,在灯罩四周的侧壁内设有导流通道,在灯罩下端面的边缘设有导流孔,导流孔通过导流通道与灯罩上端面设置的气仓连通。本实用新型的导风散热罩,其结构简单,设计合理,在不增加部件的情况下,将LED灯产生的热量及时释放,提高散热效果,同时又提高照明效率,节省资源能源,降低产品成本。

Description

一种LED路灯用的导风散热灯罩技术领域[0001] 本实用新型涉及一种散热灯罩,具体说的是一种LED路灯用的导风散热灯罩。 背景技术[0002] 现在LED灯逐渐替代传统白炽灯,成为一种新型的节能灯具。传统白炽灯钨丝灯耗能高、寿命短,随之替代产品是电子节能灯,电子节能灯虽然提高了节能效果,但由于使用了诸多污染环境的重金属元素,又有悖于环境保护的大趋势。随着LED技术的高速发展 LED照明逐渐成为新型绿色照明的不二之选。LED在发光原理、节能、环保的层面上都远远优于传统照明产品。而LED灯也被用于路灯上,然而路灯照明时间长,很难解决LED灯在使用时产生大量的热量,若不及时散热会降低LED灯的使用寿命。实用新型内容[0003] 本实用新型提供一种LED路灯用的导风散热罩,在原有灯罩的基础上,改变造型, 提高LED灯的散热效果。[0004] 本实用新型为解决上述技术问题的不足而采用的技术方案是:一种LED路灯用的导风散热灯罩,在灯罩四周的侧壁内设有导流通道,在灯罩下端面的边缘设有导流孔,导流孔通过导流通道与灯罩上端面设置的气仓连通。[0005] 所述的导流孔为圆形、方形、菱形、半圆形或梯形。[0006] 所述的导流通道为圆形、方形、菱形、半圆形或梯形。[0007] 本实用新型的有益效果是:对原有灯罩结构的进行改变,其结构设计简单、合理, 在不增加部件的情况下,将LED灯产生的热量及时释放,提高散热效果,同时又提高照明效率,节约能源消耗,降低产品成本。附图说明[0008] 图1为本实用新型的剖视图;[0009] 图2为本实用新型的俯视图;[0010] 图中:1、导流孔,2、灯罩,3、散热通道,4、气仓。具体实施方式[0011] 如图所示,一种LED路灯用的导风散热灯罩,在灯罩2四周的侧壁内设有导流通道 3,在灯罩2下端面的边缘设有导流孔1,导流孔1通过导流通道3与灯罩2上端面设置的气仓4连通。[0012] 所述的导流孔1为圆形、方形、菱形、半圆形或梯形。[0013] 所述的导流通道3为圆形、方形、菱形、半圆形或梯形。[0014] 在上述技术方案中,路灯用的导风散热灯罩,LED光源的散热板直接紧贴于带光效能的椭圆凹区中央顶部,使光源发光时产生的热量迅速传至上层的气仓4内,当气仓4内气体受热膨胀时,气体由垂直向顶部的与地面成90°角并具有一定高度的散热通道3排除, 从而把下边缘导流孔1的低温气体带入气仓4内,从此不断将LED光源散热板产生的热量带走,从而为LED光源使用提供了可靠的保障。通过简单的结构设置实现了空气的自然流动,有效提高了灯罩的散热效率。[0015] 在上述技术方案中,设计的路灯用导风散热灯罩,当含有LED光源散热板时,由 LED光源散热板将电能转化成光,由于灯罩2为漏斗状设计,当光线照射在灯罩2的内壁上, 将光源集中在一处,提高照明亮度,从而减少光源浪费,提升光源的利用率。
