Abstract

本实用新型公开了一种LED灯管，包括由散热器和灯罩相互扣合组成的管体，管体两端设有插针，散热器位于管体内的侧面设有铝基板，铝基板上设有LED，散热器位于管体外的侧面上设有若干垂弯曲的散热筋。本实用新型带有散热器的LED灯管的散热器上设有若干弯曲的散热筋，扩大了散热面积，提高了散热效果，延长了使用寿命。

Description

一种带有散热器的LED灯管
技术领域
本实用新型涉及一种照明工具，尤其涉及一种带有散热器的LED灯管。
背景技术
目前，采用发光二极管(LED)灯管的照明技术已经被广泛应用工业生产或生活中的方方面面。现有的LED灯管一般包括两端开口的透明灯管，灯管内设有多个LED以及插置于灯管内的电路板，透明灯管一般由有机玻璃管或PC管制成。
据统计，现有的LE灯管无论其外形如何，只有将近15％的电能被利用，其余的85％都以热的形式释放，因此，随着亮度的增加LED灯具在使用时会产生发热的问题，从而影响LED发光效应，在发热效应下严重衰减，导致其寿命大大缩短。
中国专利200720141004.7公开了一种LED灯管结构，其主要包括:一灯壳，其上配设有发光二极体LED，而两边设有灯管插头，以及；一金属散热片，设于灯壳的另侧，与发光二极体LED根部相贴触。
该专利公开的LED灯管散热效果欠佳，导致使用寿命较短。
发明内容
本实用新型提供了一种散热效果好、使用寿命长的带有散热器的LED灯管。
一种LED灯管，包括由散热器和灯罩相互扣合组成的管体，管体两端设有插针，散热器位于管体内的侧面设有铝基板，铝基板上设有LED，散热器位于管体外的侧面上设有若干弯曲的散热筋。
本实用新型提供了一种带有散热器的LED灯管，其散热器上设有弯曲的散热筋，扩大了散热面积，提高了散热效果，延长了使用寿命。
附图说明
图1为本实用新型带有散热器的LED灯管外观图；
图2为图1所示LED灯管A-A剖面图；
图3为图1所示LED灯管B-B剖面图。
具体实施方式
如图1、图2和图3所示，一种带有散热器的LED灯管，包括由散热器2和灯罩3扣合组成的管体1，散热器2位于管体1内的侧面上设有铝基板9，铝基板9上设有LED10，散热器2位于管体1外的侧面上设有若干弯曲的散热筋4。
散热器2上设有与管体1轴线平行的滑道，灯罩3通过滑道与散热器2相互扣合。
为了防止电源反接，铝基板9上焊接有桥堆8。
管体1的两端套有塑料接头6，塑料接头6内部设有固定片，固定片上设有第一固定杆11，第一固定杆11插入由散热筋4围成的第一固定孔13内，从而实现定位，散热器2的两端中心设有由散热筋4围成的中心孔12，螺母穿过固定片钻入中心孔12内，从而固定塑料接头6连接在散热器2上。
塑料接头6外壁上套有灯头7，灯头7上设有插针5。
散热器2安装铝基板8的侧面上设有与铝基板8相配合的凹槽，铝基板8置于凹槽内，且铝基板8的厚度与凹槽的高度相一致，外形美观。
