Description

一种LED灯 技术领域
本发明涉及灯具领域，尤其是关于一种LED灯。
背景技术
目前，大多数LED灯的结构一般包括LED发光模块、热沉和散热模块，其中的散热模块通常只有一个面上排布有散热鳍片。热沉连接LED发光模块和散热模块，LED发光模块产生的热量通过热沉传递给散热模块，散热模块再将热量通过散热鳍片散发到外界环境中。但是，这是这种散热模块散热效果欠佳，而且LED灯的组装也较繁琐。
技术问题
本发明所要解决的技术问题是，提供一种组装简单方便、散热效果好的LED灯。
技术解决方案
本发明解决其技术问题所采用的技术方案是：一种 LED 灯，包括散热模块和 LED 发光模块，所述散热模块包括基体，所述基体上设有散热鳍片，所述基体具有底面和顶面，所述底面的中间部位具有安装部，所述 LED 发光模块固定于所述安装部。
一种 LED 灯，包括散热模块、 LED 发光模块、光学透镜及恒压电源，所述散热模块包括基体及设于所述基体的散热鳍片，所述基体具有安装部，所述 LED 发光模块固定于所述安装部，所述光学透镜与所述基体固定并罩住所述 LED 发光模块，所述恒压电源与所述基体固定并与所述 LED 发光模块电连接。
所述基体具有底面和顶面，所述安装部设于所述底面，所述恒压电源固定于所述顶面。所述第一散热鳍片有多个，各所述第一散热鳍片呈 7 型，各所述第一散热鳍片的尖部朝向所述安装部，各所述第一散热鳍片的开口朝外。所述第二散热鳍片有多个并阵列分布，相邻列之间形成总导沟，相邻行之间形成支导沟，所述总导沟和支导沟相通。第一散热鳍片呈 7 型指第一散热鳍片可以包括不平行不重合而构成夹角的两部分，该两部分可以连接也可以断开；该两部分的间距可以由内至外依次增大，该内外以安装部为参照，该间距最小处即可以称为该 7 型第一散热鳍片的尖部。
 有益效果
相对于现有技术来说，本发明取消了LED发光模块和散热模块之间传递热量的热沉，而是直接将LED发光模块固定在散热模块中间部位的安装部上，一方面使LED灯的组装变得简单方便；另一方面，LED发光模块产生的热量直接传递给散热模块，由散热模块通过散热鳍片散发到外界环境中，散热速度快，散热效果好。
 附图说明
图1为本实施方式LED灯的外观立体示意图，该LED灯呈底朝上、顶朝下放置；
图2为本实施方式LED灯的立体分解图；
图3为本实施方式LED灯的俯视图；
图4为图3中沿A-A线的剖视图
图5为本实施方式LED灯的仰视图；
图6为本实施方式LED灯的主视图；
图7为图6中沿B-B线的剖视图。
 本发明的实施方式
如图1至图7所示，本实施方式的LED灯包括光学透镜1、散热模块2、LED发光模块3、恒压电源31和用于将整个LED灯固定在其它物体上的灯杆固定座42。散热模块2包括基体20，该基体20具有底面27和顶面28，其中，基体20上设有散热鳍片26，散热鳍片26包括设置在底面27上的第一散热鳍片21和设置在顶面28上的第二散热鳍片23。底面的中间部位具有安装部22，LED发光模块3固定于安装部22，光学透镜1 盖设在LED发光模块3的外面；恒压电源31向LED发光模块3供电，恒压电源31位于第二散热鳍片23的边缘上；灯杆固定座42通过支架41固定在散热模块2上。
本实施方式中，基体20、第一散热鳍片21和第二散热鳍片23为一体成型件。其中，基体20底面中间部位的安装部22可以为凹槽， LED发光模块3固定在该凹槽中。第一散热鳍片21和第二的散热鳍片23的片面均为弧形设计，以降低风阻系数。如图3所示，第一散热鳍片21围绕安装部22呈7字形排列，该7字形排列的尖部对着安装部22，该7字形排列的开口朝外，利于热量从中间部位向周边扩散。如图4至图7所示，第二散热鳍片23呈多列排布，两两相邻的列之间设有总导沟24，每一列的第二散热鳍片23平行间隔排布，两两相邻的第二散热鳍片23之间设有支导沟25，总导沟24和支导沟25相通，利于散热及疏通各支导沟24的灰尘和雨水。对于第一散热鳍片，第一散热鳍片可以有多个并可以呈7型，各第一散热鳍片的尖部对着安装部。对于第二散热鳍片，其有多个并可以呈阵列分布，每行第二散热鳍片之间形成所述支导沟，每列第二散热鳍片之间形成所述总导沟，总导沟和支导沟相通。第一散热鳍片和第二散热鳍片也可以采用其他形状和其他分布形式。对于安装部，其可以是凹槽，也可以是凸起，或者是其他能够起到直接安装LED发光模块的结构。
相对于现有技术来说，本实施方式取消了LED发光模块3和散热模块2之间传递热量的热沉，而是直接将LED发光模块3固定在散热模块2中间部位的安装部22上，一方面使LED灯的组装变得简单方便；另一方面，LED发光模块3产生的热量直接传递给散热模块2，由散热模块2通过第一散热鳍片21和第二散热鳍片23散发到外界环境中，散热速度快，加上散热模块2的基体20的两个面(即底面和顶面)都排布有散热鳍片，散热鳍片的数量大幅度地增加了，散热面积也就大幅度地扩大了，进一步地提高了散热速度，因此，散热效果好。另外，本实施方式还可以取消现有技术中罩在散热模块外面的壳体，更进一步地提高了散热效果。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
