Description

说 明 书 一种散热片
技术领域：
本实用新型涉及散热技术领域， 尤其涉及一种散热片。
背景技术：
照明灯泡已广泛应用于城市道路、 庭院、 走道、 车库、 办公场 所、 公共场所等场合的照明， 给人们的生活带来诸多便利。 常用的 照明灯泡类型有钨丝灯泡、 日光灯和 LED灯泡等， 其中 LED灯泡 因具有高效、 安全、 节能、 环保、 寿命长、 响应速度快等优点， 已 逐渐成为应用最广泛的照明灯泡。
现有的 LED灯泡， 工作时会产生大量的热量， 这些热量如果不 及时散发出去， 将会影响 LED灯泡的使用寿命。然而， 现有的 LED 灯泡， 其灯座的散热效果并不理想。
实用新型内容：
本实用新型的目的在于针对现有技术的不足， 提供一种可用于 LED灯泡， 散热效果理想的散热片。
为实现上述目的， 本实用新型通过以下技术方案实现： 一种散 热片， 它包括铝合金散热体， 铝合金散热体内部开始有连通上端和 下端的安装通孔， 铝合金散热体外侧壁设置有散热鳍片。
所述散热鳍片的外侧边为曲形边。
所述散热鳍片的外侧边为弧形边。 所述铝合金散热体的上端的面积大于下端的面积。
所述安装通孔的孔壁开设有与安装通孔的孔轴平行的嵌装槽。 所述铝合金散热体的下端开设有安装沉台。
本实用新型有益效果为： 所述的一种散热片， 它包括铝合金散 热体， 铝合金散热体内部开始有连通上端和下端的安装通孔， 铝合 金散热体外侧壁设置有散热鳍片。 将上述结构的散热片应用于 LED 灯泡， 灯头装设于铝合金散热体的上端并穿过安装通孔， LED灯和 灯罩装设于铝合金散热体的下端， 工作时， LED灯所产生的大量热 量经由铝合金散热体散热至外部， 其中， 安装通孔和散热鳍片能大 大提高散热效果， 因此， 本实用新型可用于 LED灯泡， 且散热效果 理想， 可提高 LED灯泡的使用寿命。
