Description

具有散热功能的发光二极管灯条构造 技术领域
本发明涉及一种发光二极管灯条构造，特别是涉及一种具有散热功能的发光二极管灯条构造。
背景技术
液晶显示器面板(LCD panel)现已广泛应用于监视器、笔记型电脑、数字相机及投影机等具成长潜力的电子产品。LCD面板制造商在产生玻璃基板之后，须先结合彩色滤光片，两者封合后灌入液晶，再与背光模块、驱动IC、控制电路板等组件共同组合成LCD模块出售给下游的笔记型电脑或LCD监视器制造商。
背光模块(Back light module)为液晶显示器面板的关键零组件之一，由于液晶本身不发光，背光模块的功能即在于供应充足的亮度与分布均匀的光源，使其能正常显示影像。背光模块主要由光源、灯罩、反射板(Reflector sheet)、导光板(Light guide plate)、扩散片(Diffuser sheet)、增亮膜(Brightness enhancement film)及外框等组件组装而成。
一般而言，背光模块可依其规模的要求，以灯管的位置做分类，发展出侧光式(Edge lighting)结构与直下型(Bottom lighting)结构。其中，侧光式结构的发光源为摆在侧边的单支光源；直下型结构的光源则放置于正下方。背光模块所用的灯管须具备亮度高及寿命长等特色，目前有冷阴极萤光灯管(Cold cathode fluorescent lamp，CCFL)、热阴极萤光灯管、发光二极管(Light emitting diode，LED)及电激发光(EL)等。
其中，冷阴极萤光灯管具有高辉度、高效率、寿命长、高演色性等特性，加上圆柱状外形因此很容易与光反射元件组合成薄板状照明装置，因此，以冷阴极萤光灯管为主的背光源曾是背光模块的主流。然而，冷阴极萤光灯管由于管内含有汞蒸气，因此，在环保意识高涨的今天逐渐被趋势所淘汰。由于发光二极管(LED)做为背光光源比冷阴极荧光灯管(CCFL)具有节能环保等优势，因此以LED取代CCFL将是背光发展的趋势，业界通常称发光二极管的发光构造为灯条(Light bar)。
请参照图1所示，图1是一种现有发光二极管灯条构造的立体图。如图1所示，一发光二极管灯条构造90包含一约呈长条形的电路板91及多个发光二极管92，所述多个发光二极管92是排列在所述电路板91的上表面上，并通过多个焊点93固定及电性连接所述电路板91。所述发光二极管灯条构造90可以模拟出传统背光模块所采用的冷阴极萤光灯管发光源的效果。不论是侧光式的背光模块结构或直下型的背光模块结构，所述发光二极管灯条90可直接用于原来装设冷阴极萤光灯管的位置，以取代冷阴极萤光灯管的照射。虽然使用发光二极管作为背光源具有轻薄、环保、省电等等的优点，但是上述的现有发光二极管灯条仍存在一些问题：
(一) 发光二极管的加工工艺较为复杂，目前发光二极管通过焊接的方式固定于印刷电路板(PCB)上，所以在加工工艺上较为复杂；
(二) 发光二极管灯条的散热较不易，由于在背光模块的内部空间中自然对流不易，因此发光二极管所产生的热能只能通过所电路板91间接传导散热，因此发光二极管灯条普遍存在散热不易的问题。

 本发明的最佳实施方式
让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明如下：
本发明的发光二极管灯条(Light bar)构造是应用于背光模块中，所述背光模块并不限定于特定的型式，其可以是侧光式(Edge lighting)结构或直下型(Bottom lighting)结构，关于发光二极管灯条构造使用于背光模块的情形，请参照背景技术中的相关描述，在此不再赘述。
请同时参照图2及图3所示，图2揭示本发明较佳实施例的一种具有散热功能的发光二极管灯条构造的立体分解图；图3是由另一视角来揭示本发明较佳实施例的一种具有散热功能的发光二极管灯条构造的立体组装状态图。如图2及图3所示，所述发光二极管灯条构造1包含一散热本体10、多个发光二极管20及一电路板30。所述散热本体10约呈长条状，并具有相对应的一第一表面11及一第二表面12，所述第一表面11上排设有多个安装孔13，所述第二表面12上设有一电路板安装槽14，所述多个安装孔13贯穿所述第一表面11至所述电路板安装槽14。
另外，如图2及图3所示，所述多个发光二极管20分别具有一顶部21、及一底部22，并对应嵌入所述散热本体10的所述多个安装孔13内，所述顶部21朝向所述散热本体的第一表面11，所述底部22朝向所述散热本体10的电路板安装槽14并设有多个第一接点24。所述发光二极管20发射的光线是通过所述顶部21向外射出。所述底部22可以是所述发光二极管20的电路基板或导线架(leadframe)。
再者，如图2及图3所示，所述散热本体10的所述电路板安装槽14是一抽屉状开槽，所述抽屉状开槽具有类似于“凸”字形的开槽剖面形状。所述电路板30可通过横向滑移嵌入所述电路板安装槽14，并组装至定位。必要时，所述电路板30可通过多个螺固元件(未绘示)的辅助，来加强固定于所述散热本体10的强度。所述电路板30上表面31对应所述多个发光二极管20的多个第一接点24设有多个第二接点32。当所述电路板嵌入定位后，所述多个第二接点32与所述多个第一接点24电性连接。
请参照图4所示，图4揭示本发明较佳实施例的一种具有散热功能的发光二极管灯条构造的剖视图。如图4所示，所述多个发光二极管20的周面23呈斜面，所述安装孔13的壁面对应亦为斜面。在本发明较佳实施例的所述多个发光二极管20是约呈一梯形体,也就是所述多个发光二极管20的周面23有两组侧面(一组长度方向的侧面及一组宽度方向的侧面)中，其中至少一组具有一向顶面21方向内倾的斜面。同时，所述安装孔13的内径是由所述第一表面11向所述第二表面12变宽。因此，如图4所示，所述多个发光二极管20即可由所述散热本体10的所述第二表面12上的电路板安装槽14的方向，将所述多个发光二极管20嵌入所述多个安装孔13，以达嵌入卡掣组装结合的效果。
请参照图5所示，图5揭示本发明较佳实施例的发光二极管的立体图。如图5所示，所述多个发光二极管20的多个第一接点24优选是一弹性导电结构，例如弹性金属片。所述弹性金属片的第一接点24在被抵接时可产生向外的弹性恢复力，以弹性抵撑所述电路板30上的第二接点32，如此可以确保使所述发光二极管20的第一接点24与所述电路板30上的第二接点32的电性连接质量良好。但是，本发明并不限制所述弹性金属片的型式。
因此，本发明先通过将所述发光二极管20安装于所述散热本体10的所述多个安装孔13内，再将所述电路板30横向滑移嵌入所述散热本体10的所述电路板安装槽14，以固定并电性连接所述多个发光二极管20，如此可简化所述发光二极管灯条构造1的加工工艺，省略现有焊接发光二极管至电路板的加工工艺。并且，通过所述发光二极管20的周面23与所述散热本体10的安装孔13的壁面紧密的嵌设贴合，使所述散热本体10可直接侧向导出所述多个发光二极管20所产生的热能(如图4箭头方向)，从而提高所述背光模块(未绘示)整体的散热效率。
另外，虽然本发明较佳实施例揭示的所述多个发光二极管20呈一梯形体，其具有一组对应的斜面(如图4所示)，并且所述散热本体10的安装孔14的形状与所述发光二极管20的所述斜面相对应。但本发明并不限制所述多个发光二极管20的具体外形，所述多个发光二极管20也可能是多边体或圆柱体，或者所述多个发光二极管20也可具有阶状的周面23。本发明也不限制所述多个发光二极管20的周面23有多少个表面必须是斜面，所述多个发光二极管20的周面23的至少一表面是呈斜面，即能达成使所述多个发光二极管20定位及增加所述多个发光二极管20与所述散热本体10的接触面积的效果。并且，所述散热本体10优选是一具良好热传导性及机械强度的材料所制成，例如所述散热本体10是一金属或合金材质的散热框条，特别是一铝挤成型的散热框条。另外，所述散热本体10在所述电路板安装槽14中也可以额外形成一长条形浅沟槽，以侧向连通相邻的所有安装孔13，如此可减少铝挤成型后加工制做所述安装孔13的钻孔加工量。
再者，如图2及图3所示的,所述散热本体10的所述电路板安装槽14是一抽屉状开槽，所述电路板30由横向嵌入所述电路板安装槽14，以达到固定所述多个发光二极管20与所述电路板30的目的。然而，本发明并不限制所述电路板安装槽14的安装形式，所述电路板30也可能以别的方式嵌入所述电路板安装槽14。或者，所述散热本体10也可能不具有所述电路板安装槽13，所述散热本体10的安装孔13是贯穿所述散热本体10的所述第一表面11至所述第二表面12；所述电路板30可直接固定于所述散热本体10的第二表面12上，例如以螺固元件(未绘示)来固定所述电路板30。
综上所述，相较于现有的发光二极管灯条的加工工艺较为复杂，且散热较不易。本发明通过将所述发光二极管20安装于所述散热本体10的所述多个安装孔13内，再将所述电路板30嵌入所述散热本体10的所述电路板安装槽14，以固定并电性连接所述多个发光二极管20，如此可简化所述发光二极管灯条构造1的加工工艺。并且，通过所述发光二极管20的周面23与所述散热本体10的安装孔13的壁面紧密的嵌设贴合，使所述散热本体10可直接侧向导出所述多个发光二极管20所产生的热能，从而提高所述背光模块(未绘示)整体的散热效率。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
