具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。
实施例一
本发明实施例中提供了一种直下式背光模组,如图1所示,包括:背板4、以及位于背板4上的多个灯条1,每一个灯条1上设有由多个发光二极管11组成的灯组,还包括:
多根导线3;
灯组具有正/负两个接线端,每一个灯条1上,如图2所示,灯组的正接线端与对应的导线3之间通过一对相互卡合的插头22和插槽21实现电连接;灯组的负接线端与对应的导线3也通过同样的方式实现电连接。
本发明提供的直下式背光模组,在组装灯条时,可以通过导线3、以及每一对插头22和插槽21卡合实现多个灯条中每一个灯条1之间的串联或者并联。
本发明提供的直下式背光模组,在组装灯条时,避免了上述背景技术中提到的通过直接焊接在印刷电路板上实现多个灯条中每一个灯条之间的串联或者并联。
所以,本发明提供的直下式背光模组,便于安装和单独更换单个灯条。
进一步地,如图3所示,上述每一对插头22和插槽21中,插槽21设有卡口211;如图4所示,上述插头22朝向卡口211的一面具有弹片221,弹片221的一端设有与卡口211卡合的弯折部222。将插头22***插槽21内的过程中,插头21上的弹片221将向背离卡口211的一面压缩变形,当弯折部222位于卡口211下方时,弹片221弹起,从而带动弯折部222卡合在卡口211内。更好的实现插头22和插槽21的卡合配合。
为了便于将插头22***插槽21中,优选地,上述卡口211位于插槽21背离灯条1的一侧。
为了便于实现单个灯条1之间的串联或者并联,如图1,优选地,每一个灯条1中,与灯组的正接线端对应的插槽21设置于灯条1的一端,与灯组的负接线端对应的插槽21设置于灯条1的另一端。
如图1所示,上述背板4上还设有允许导线3与电源电连接的出线口41,将各个灯条1串联或者并联后,将导线3从背板4上设有的允许导线3与电源电连接的出线口41。
每一个插槽21可以通过多种方式固定在每一个灯条1上:
方式一
每一个插槽21焊接在对应的灯条1上。通过焊接的方法固定插槽21可以防止接触不良的现象发生。
方式二
每一个插槽21可拆卸的安装于对应的灯条1上。插槽21可以通过卡扣安装,也可以通过其它方式安装,这里就不再一一赘述,可拆卸的安装插槽21,当对应的灯条1坏掉时,可以单独更换灯条1,节约成本。
如图5所示,为了便于将插头22从插槽21中拔出,本发明还提供了一种开启弯折部222的翘针23。当需要将插头22从插槽21中拔出时,可以用翘针23向下压插头22的弯折部222,弹片221将向背离卡口211的一面压缩变形,从而使得弯折部222从卡口211中退出,进而方便插头22从插槽21中拔出。
上述方式二中,插头22和插槽21的材料可以为塑料,也可以为金属材料以,也可以采用其他的材料,这里就不再一一赘述。
实施例二
本发明实施例还提供了一种显示装置,包括显示面板,还包括上述直下式背光模组。
本发明实施例提供的显示装置,在组装时,由于具有上述直下式背光模组,故在安装灯条1时,可以通过插头22和插槽21的卡合配合,从而实现单个灯条1间的串联或者并联,从而可以节约人力和时间,所以,本发明提供的显示装置,具有较高的生产效率。
显然,本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
