一种发光二极管灯具，包括一灯架及贴设于灯架上的若干发光二极管模组，所述灯架包括一本体部及自所述本体部一侧向外延伸的一承载部，所述发光二极管模组贴设于所述承载部上。与现有技术相比，本发明的发光二极管灯具采用发光二极管模组作光源，节能环保。

Description

发光二极管灯具
技术领域
本发明涉及一种照明装置，特别是指一种发光二极管灯具。
背景技术
目前市场上销售的灯具品种繁多，如高压钠灯、卤素灯等。然而，这些灯具使用寿命不长且耗电量大，不能满足节能环保的要求。
发明内容
有鉴于此，有必要提供一种节能环保且使用寿命长的灯具。
一种发光二极管灯具，包括一灯架及贴设于灯架上的若干发光二极管模组，所述灯架包括一本体部及自所述本体部一侧向外延伸的一承载部，所述发光二极管模组贴设于所述承载部上。
与现有技术相比，本发明的发光二极管灯具采用发光二极管模组作光源，节能环保。
下面参照附图，结合具体实施例对本发明作进一步的描述。
附图说明
图1是本发明一实施例中发光二极管灯具的组装图。
图2是图1中发光二极管灯具的分解图。
图3是图2的倒置图。
主要元件标号说明
Figure B200910310700XD0000021
具体实施方式
请参阅图1及图2，本发明一实施例的发光二极管灯具包括一灯架10、收容于灯架10内的一发光二极管模组20、安装于灯架10且罩设发光二极管模组20的一透明灯盖30及压设灯盖30的一抵压件40。
请同时参阅图3，该灯架10可由一体挤压成型(例如，铝挤成型)，大致呈L形。该灯架10包括一本体部11及自本体部11一侧顶端向外垂直延伸的一纵长承载部13。该承载部13的顶表面向上延伸有若干平行且间隔的散热片131，用以散发承载部13吸收的热量。该承载部13的底表面为一平面，用于与发光二极管模组20导热连接。这些散热片131的顶端与本体部11的顶端共面。
该本体部11为连续三向具开口的、内空的长方体。该本体部11与承载部13相远离的一端具有一第一开口111、与承载部13相对两侧相连的左右两端具有二第二开口113。二纵长的侧壁112分别与本体部11的左右两端密封连接，从而使本体部11具有第二开口113的左右相对两端封闭。一驱动电路模组114收容于本体部11内，并于发光二极管模组20电性连接，用于驱动发光二极管模组20。
一连接部60与该本体部11具有第一开口111的一端密封连接。该连接部60包括一纵长的挡板61及自挡板61一侧中部向外延伸的、一内空的、圆柱状灯头63。该挡板61的尺寸与本体部11第一开口111所在一侧的尺寸相当，且与该侧密封连接，从而使本体部11内形成一密封的腔体。该灯头63用于与灯杆(图未示)连接，从而使发光二极管灯具可做路灯使用。一内空的防水螺栓17穿设并固定于挡板61中部且与灯头63连通，用以供自驱动模组114延伸的导线(图未示)穿出并与外部电源电性连接。
可以理解地，当该发光二极管灯具用作壁灯时，该灯头63并非必要元件，此时，使挡板61的一端超出本体部11，使螺钉(图未示)等固定件直接穿过挡板61，而将挡板61固定至墙壁上。如此，发光二极管灯具可做壁灯使用。
每一发光二极管模组20包括一纵长的电路板21及间隔排列于电路板21一侧的若干发光二极管23。这些发光二极管23沿电路板21的延伸方向排列成一纵行。这些发光二极管模组20的电路板21平行且间隔的固定于承载部13的下表面且其未设置发光二极管23的一侧表面与承载部13的下表面导热连接，用以将发光二极管模组20的热量传导至承载部13上。
该灯盖30包括一内空且呈长方形的边框31、自边框31一端垂直向下延伸的一侧板33及连接边框31及侧板33的一连接板35。该边框31的长度及宽度略小于灯架10的承载部13的长度及宽度。该侧板33的长度及高度略小于灯架10的本体部11与第一开口111相对一侧的长度及高度，且贴设于本体部11的该侧。该连接板35为光滑的弧形板体，由透明或半透明的材料制成。连接板35各边缘分别连接边框31内侧连续的三边缘及侧板33的最底端，且连接板35距边框31所在平面的高度自远离侧板33的一端向侧板33所在一端递增。如此，边框31、侧板33及连接板35共同形成一侧开口的收容空间(未标号)。
所述抵压件40的形状与灯盖30相似，包括一长方形、内空的第一抵压部41及自第一抵压部41一端垂直向下延伸的一第二抵压部43。该第一抵压部41的内侧端抵压灯盖30的边框31。一长方形垫圈50夹设于边框31及第一抵压部41的内侧端，以增强灯盖30与抵压件40之间的密封性。该第二抵压部43为一大致呈长方体、具有二贯穿开口431的支架。开口431的尺寸与灯盖30的侧板33的尺寸相当，用于抵压侧板33。若干固定件(图未示)，如螺钉等穿过第一抵压部41各边的外端边缘并与灯架10的承载部13配合，从而将抵压件40、灯盖30固定至承载部33上。
