Description

直下式灯条的连接线结构及其连接方法 技术领域
本发明涉及背光技术领域, 尤其涉及一种直下式灯条的连接线结构及 其连接方法。 背景技术
近年来, 随着平板显示技术的快速发展, 液晶显示器因其具有体积 小、 重量轻、 画质高及驱动电压低等优点而被广泛应用于各种信息、 通讯 及消费性产品中。 由于液晶显示器的液晶显示面板中液晶本身不具有发光 特性, 因而为调整液晶显示器的显示亮度, 需要给液晶显示器的液晶显示 面板提供一光源装置, 如背光模组, 从而用于向液晶显示面板提供亮度充 分且分布均勾的光束。 按照背光模组相对于液晶显示面板的位置, 可分为 背光源安装在液晶面板后方的直下式背光模组和背光源安装在液晶面板四 周边缘的侧入式背光模组。
随着背光模组中背光源技术的快速发展, LED 背光逐步进入产业化, 从而逐渐取代冷阴极荧光灯管 (CCFL ) 成为背光模组中背光源的主流。 因而直下式背光模组中, LED也作为背光源来逐渐取代灯管。
在目前采用 LED作为背光源的背光模组中, LED 晶片通过贴附到柔 性印刷线路板 ( FPC ) 或印刷电路板 (PCB ) 上形成 LED 灯条 (light bar ) , 从而作为背光源应用到液晶显示面板的背光模组中。 在现有直下式 背光模组中, 灯条( light bar )数量较多, 利用端子彼此之间连接起来。 如 图 1 所示, 其为现有直下式灯条的连接线结构示意图。 现有直下式灯条的 连接线结构包括数个灯条 100, 数条连接线 (Wire ) 200, 电路板 300, 打 件在电路板 300上的胶壳连接器( Housing )母端 301 , 每个灯条 100通过 打件设置的胶壳连接器母端 103, 以及用于连接连接线 200 的数个胶壳连 接器公端 201。 其中, 胶壳连接器公端 201是和连接线 200通过贴片机牢 固的打件在一起的, 按照一个胶壳连接器公端 201连接两条连接线 200之 间的方式将所有胶壳连接器公端 201和连接线 200顺序连接在一起形成线 材组。 其中, 灯条 100包括线路板 102和设置于线路板 102上的多个 LED 晶片 101 , 线路板 102可以为 FPC或 PCB, 灯条 100上还包括通过打件设 于末端的胶壳连接器母端 103。 通过胶壳连接器公端 201 与胶壳连接器母 端 103及胶壳连接器母端 301按照公端配合母端的方式——对应连接, 将 灯条 100、 连接线 200及电路板 300连接成回路, 实现灯条 100的背光功 能。 该方式有一个很大的缺陷就是: 如果增加或者减少一条灯条 100 的使 用, 必须增加或减少胶壳连接器公端 201 的使用; 由于胶壳连接器公端 201 和连接线 200是通过打件牢固的连接在一起, 如果采用该方法的话必 须重新再打件制作一条连接线 200; 这样不仅浪费线材成本, 而且线材的 共用性也很差。 发明内容
因此, 本发明的目的在于提供一种新的直下式灯条的连接线结构及其 连接方法, 以满足灯条数量增加或减少等情况下的连接线的共用。
为实现上述目的, 本发明提供一种直下式灯条的连接线结构, 包括数 个灯条、 数根连接线、 以及电路板, 每个所述灯条的线路板设有带孔的第 一棵铜区作为电路连接点, 所述电路板设有带孔的第二棵铜区作为电路连 接点, 每根所述连接线两端各连接一个铜环, 每一连接线的两个铜环分别 通过连接件连接至对应的第一棵铜区或第二棵铜区的孔以使电路导通。
其中, 所述连接件为螺丝。
其中, 所述连接件为插销。
其中, 所述铜环通过打件连接至所述连接线两端。
本发明还提供了一种直下式灯条的连接方法, 包括:
步骤 10、 在每根连接线的两端各连接一个铜环;
步骤 20、 在每个灯条的线路板上留出带孔的第一棵铜区作为电路连接 点;

附图中,
图 1为现有直下式灯条的连接线结构示意图;
图 2为本发明直下式灯条的连接线结构一较佳实施例的结构示意图; 图 3为图 2的实施例组装后在灯条上的导通位置的截面示意图; 图 4为本发明直下式灯条的连接方法一较佳实施例的流程图。 具体实施方式
参见图 2, 其为本发明直下式灯条的连接线结构一较佳实施例的结构 示意图。 本发明的直下式灯条的连接线结构包括数个灯条 1、 数根连接线 2、 以及电路板 3 , 灯条 1 包括线路板 12 和设置于线路板 12 上的多个 LED晶片 11 , 线路板 12可以为 FPC或 PCB , 每个灯条 1的线路板 12设 有带孔的棵铜区 13作为电路连接点, 电路板 3设有带孔的棵铜区 31作为 电路连接点, 每根连接线 2两端各连接一个铜环 21 , 组装时, 按照预设的 灯条回路, 将每一连接线 2 的铜环 21 分别通过连接件连接至对应的棵铜 区 31或 13的孔以使电路导通。 其中, 所述连接件可以为螺丝或插销。 铜 环 21可以采用贴片机通过打件连接至连接线 2的两端。
参见图 3 , 其为图 2 的实施例组装后在灯条上的导通位置的截面示意 图。 连接件 4插入对应的铜环 21和线路板 12上的棵铜区 13 中央的孔, 从而实现电性连接。
参见图 4 , 其为本发明直下式灯条的连接方法一较佳实施例的流程 图。 本发明的直下式灯条的连接方法包括:
步骤 10、 在每根连接线的两端各连接一个铜环;
步骤 20、 在每个灯条的线路板上留出带孔的第一棵铜区作为电路连接 点;
步骤 30、 在电路板上留出带孔的第二棵铜区作为电路连接点; 步骤 40、 每一连接线的两个铜环分别通过连接件连接至对应的第一棵 铜区或第二棵铜区的孔以使电路导通。
本发明的连接方法较传统方式, 取消了跟连接线线材打件在一起的胶 壳连接器公端的使用, 同时, 也省去了电路板和灯条上面胶壳连接器母端 的使用, 大大节约成本。 在每根连接线的两端各打件上一个铜环, 在电路 板板端原来打胶壳连接器母端的位置留出带孔的棵铜区, 将连接线的铜环 孔中心和电路板端的棵铜区中间的孔对齐, 利用插销或螺丝将二者固定在 一起, 实现电路的导通。
综上所述, 本发明的直下式灯条的连接线结构及其连接方法可以满足 灯条数量增加或减少等情况下的线材共用。 当灯条数量增加或减少时, 增 加或减少一条带铜环的连接线即可, 无需重新打件连接线材组, 节约成本 和打件周期, 实现不同类型不同数量灯条线材的共用。
以上所述, 对于本领域的普通技术人员来说, 可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形, 而所有这些改变和变形 都应属于本发明后附的权利要求的保护范围。
