液晶显示器 (liquid crystal display, LCD)是利用液晶显示图像的平板显示 装置， 比其它显示装置具有轻薄、 低驱动电压及低功耗等优点， 在显示器产 业里已得到广泛运用。 然而， 液晶显示面板不能自主发光， 故需要另外提供 独立的背光源。 又以发光二极管 (LEDM故为背光源比冷阴极荧光管 (CCFL)具 有节能、 寿命长、 体积小等优势， 因此以发光二极管取代冷阴极荧光管做为 背光源已是液晶显示器目前发展的主流趋势。
请参照图 1所示， 其揭示一种现有应用 LED的背光模块的侧剖视图。一 背光模块 90包含一框架 91、 一导光板 92、 数个光学膜片 93、 一胶框 94及 两灯条 95。 所述框架 91的两侧缘上设有垂直部 911。 所述导光板 92装设于 所述框架 91的中央位置。所述光学膜片 93设于所述导光板 92顶部。所述胶 框 94包覆于所述框架 91的外缘，并且由上而下固定所述光学膜片 93及所述 导光板 92。所述两灯条 95是分别设于所述框架 91的所述垂直部 911的内壁 上， 所述灯条 95具有数个 LED装置 951， 且其光源方向指向所述导光板 92。 所述灯条 95 —般通过螺丝锁附或导热胶带粘贴等方式来固定于所述垂直部 911上。
然而，所述背光模块 90在组装时，必需通过螺丝锁附或导热胶带粘贴等 方式来固定于所述垂直部 911上， 螺丝或导热胶带的使用会使得组装变得复 杂， 且可能发生因锁附过紧而损伤所述灯条 95， 或因导热胶带黏贴位置失准 而影响产品一致性等组装问题。 同时， 要在有限空间中进行锁附或黏贴的动 作也较困难。 再者， 也有零件数量过多， 而不易精准备料与管控物料的问题。 此外， 所述背光模块 90在使用时， 所述灯条 95周遭的温升很明显， 会有部 分所述 LED装置 951 因过热而损坏的情形发生， 因此就有更换所述灯条 95 的必要。 而在更换所述灯条 95时， 往往需要先拆掉所述导光板 92及所述光 学膜片 93， 这个过程将有可能会使所述导光板 92及光学膜片 93受到污染。
故， 有必要提供一种背光模块及其灯条定位构造， 以解决现有技术所存 在的问题。 发明内容

为让本发明上述目的、 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。 再者， 本发明所提到的方向用语， 例 如 「上」、 「下」、 「前」、 「后」、 「左」、 「右」、 「内」、 「外」 或 「侧面」 等， 仅 是参考附加图式的方向。 因此， 使用的方向用语是用以说明及理解本发明， 而非用以限制本发明。
请参照图 2所示， 图 2揭示本发明背光模块第一实施例的侧剖视图。 一 种背光模块包含一固定架 10、 至少一灯条定位构造 11， 一导光板 20、 一光 学膜片 30及至少一灯条 40。
请同时参照图 2及图 3所示，图 3揭示所述固定架 10及所述至少一灯条 40的局部分解立体示意图。 在本实施例中， 所述固定架 10是指所述背光模 块的一背板， 所述固定架 10是由铝、 铜、 铁或其它金属材料制成。 在本实施 例中， 所述固定架 10包含一水平部 12及至少一垂直部 13。 所述至少一垂直 部 13是从所述水平部 12的至少一侧缘向上延伸出。 所述至少一灯条定位构 造 11设于所述固定架 10的一侧壁上， 更详细来说， 所述侧壁是所述至少一 垂直部 13的内侧面， 所述至少一灯条定位构造 11可以是一体成型的形成于 所述至少一垂直部 13 的内侧面上。 如图 3所示， 所述至少一灯条定位构造 11 由有多个并排成齿状的夹固部 110构成， 每一所述夹固部 110可以是呈 L 形而具有一较短部 110a及一较长部 110b, 其中所述较短部 110a的一端是横 向设于所述侧壁 (亦即所述至少一垂直部 13 的内侧面: 而所述较长部 110b 则是从所述较短部 110a的另一端向上延伸出，本实施例中，所述较长部 110b 与所述至少一垂直部 13呈平行。在本实施例中，所述夹固部 110可以由冲压 加工所述垂直部 13所制成，或是直接由铝挤成型方式直接成形，但并不限于 此。
请参照图 2所示，所述导光板 20设于所述固定架 10上，在本实施例中， 所述导光板 20设于所述固定架 10的水平部 12上， 所述导光板 20的一侧缘 可以是抵靠于所述多个夹固部 110的较长部 110b。 所述光学膜片 30设于所 述导光板 20上。
请同时参照图 2及图 3所示， 所述灯条 40是固定于所述固定架 10的所 述垂直部 13的内侧面上， 受到所述灯条定位构造 11的多个夹固部 110所夹 持定位， 更详细来说， 所述灯条 40包含一电路基板 41及多个发光件 42。 所 述电路基板 41的一长边是抵靠在所述多个夹固部 110的较短部 110a上， 所 述电路基板 41受到所述垂直部 13的内侧面及所述多个夹固部 110的较长部 110b所夹固。 所述多个发光件 41是呈间隔排列而设于所述电路基板 41上， 其中每一所述发光件 41是位于两相邻的所述夹固部 110之间，且发光方向朝 向所述导光板 20。 所述发光件 41优选是发光二极管 (LED)装置。
由于本发明是利用所述多个夹固部 110的夹持来达到使所述灯条 40稳固 定位于固定架 10 上的目的， 不必通过螺丝锁附或是利用导热胶带粘贴的方 式， 不论是安装或是拆卸都很方便， 一旦灯条 40 损毁需要更换， 所述灯条 40的拆卸过程中并不需要预先拆掉所述背光模块的其它部件， 因此比较不会 影响或污染到所述背光模块的其它部件 (例如所述导光板 20及光学膜片 30)。
再者，所述导光板 20的一侧缘因为可以受到所述多个夹固部 110的较长 部 110b紧密抵靠接触， 故所述灯条定位构造 11另还具有稳固定位所述导光 板 20的效用。
请参照图 4所示， 本发明第二实施例的背光模块及其灯条定位构造相似 于本发明第一实施例， 并大致沿用相同组件名称及图号， 但第二实施例的差 异特征在于： 所述第二实施例的固定架 10是一 L形灯条框架， 其适当固定 于所述背光模块的一背板 100内， 所述固定架 10及背板 100皆是由铝、 铜、 铁或其它金属材料制成，且所述固定架 10的夹固部 110可以由冲压加工所述 垂直部 13所制成， 或是直接由铝挤成型方式直接成形， 但并不限于此。在所 述第二实施例中，所述固定架 10的夹固部 110是相同于所述第一实施例的夹 固部 110， 因此同样具有方便组装所述灯条 40及稳固定位所述导光板 20的 效用。
综上所述， 相较于现有背光模块虽能以螺丝锁附或是导热胶带粘贴的方 是稳固地将一灯条安装在一固定架上， 但当所述灯条损坏需要更换时， 所述 安装方式将不利于拆卸， 且很可能导致所述背光模块的其它部件污损， 图 3 的本发明背光模块通过在所述固定架 10 的侧壁上设置所述多个夹固部 110 来构成所述灯条定位构造 11， 以所述多个夹固部 110确实可以有效且方便固 定所述灯条 40， 同时也方便拆卸， 进而可提高背光模块组装的效率以及后续 维护的便利性。
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。
