下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参阅图1，图1为本发明较佳实施例提供的LED灯箱100的一种分解结构示意图。在本实施例中，所述LED灯箱100可以应用于婚沙摄影、家庭装饰画、室内外指示牌、大型展览工程或活动展览展示、商场、银行、宾馆、酒店、等墙面装饰宣传、机场、地铁、车站、公交站台等广告媒体、工艺礼品、流动广告牌等，本实施例对所述LED灯箱100的应用范围不作具体限制。
如图1所示，所述LED灯箱100可以包括灯箱支架110、画布130、控制器150及多个LED光源模组170。
可选地，在本实施例中，所述多个LED光源模组170固定在所述灯箱支架110上，所述画布130覆盖在所述多个LED光源模组170上并与所述灯箱支架110固定。
所述画布130与所述灯箱支架110的固定方式可以是多种，例如，在本实施例的一种实施方式中，所述灯箱支架110上可以设置有用于安装所述画布130的安装槽，所述画布130可以通过卡入所述安装槽与所述灯箱支架110卡接固定。
所述控制器150与所述LED光源模组170电性连接，可以用于对所述LED光源模组170进行控制。可选地，所述LED光源模组170的结构请参阅图2和图3，每个所述LED光源模组170可以包括多个平行排列的LED灯条171以及用于连接所述LED灯条171的灯条PCB连接件172，所述LED灯条171设置有输入端口和输出端口，所述输入端口和所述输出端口可以通过插针和/或SMT贴片与所述灯条PCB连接件172电性连接。如图2所 示，所述灯条PCB连接件172沿垂直于LED灯条171的方向延伸，所述灯条PCB连接件172位于所有所述LED灯条171的同一侧，每个所述LED光源模组170中的所有所述LED灯条171均连接于所述灯条PCB连接件172。上述连接方式具有生产方便，组装简单，连接可靠，精度高等特点。
容易理解的是，所述灯条PCB连接件172也可以不垂直于LED灯条171设置，只要保证每个所述LED光源模组170中的所有所述LED灯条171均连接于所述灯条PCB连接件172即可。此外，每个所述LED光源模组170中的所述LED灯条171也可以不相互平行排列，每个所述LED灯条171可以为直线段形式，也可以为折现段形式或曲线段形式，使所有所述LED灯条171组合成富有观赏性的形状，这样，所述LED灯条171在工作过程中可以呈现更加绚丽多彩的图案。
进一步地，作为一种优选的实施方式，所述输入端口和所述输出端口可以通过SMT贴片与所述灯条PCB连接件172电性连接，采用上述SMT贴片具有生产工艺简单、生产效率高的特点。
本实施例中，所述灯条PCB连接件172可以采用PCB电路板。
进一步地，每个LED灯条171上包括有多个串联在一起的LED灯173，所述控制器150可以通过对所述LED光源模组170采用逐行扫描的方式对所述LED光源模组170进行控制。可选地，在逐行扫描时，所述控制器150可以通过控制每个LED灯条171中的LED灯173的亮灭来实现对整个LED光源模组170的控制，可选地，所述行扫描方向为所述LED灯条171的延伸方向。
本实施例中，作为一种实施方式，所述LED灯173可以采用SMD贴片LED灯，所述SMD贴片LED灯具有使用寿命长、响应速度快、电光转换率高、耗电量小、可靠度高、易小型、薄型、轻量化，无形状限制的优点。
此外，如果将所有的LED灯173串联，将需要向LED灯173输出较高的电压；如果将所有的LED灯173并联，则需要向LED灯173输出较大的电流。而且，将所有的LED灯173串联或并联，不但限制着LED灯173的使用量，而且并联LED灯173负载电流较大。鉴于此，所述灯条PCB连接件172上可以设置有线性恒流驱动电路，从而不仅可以保证所述LED灯条171中的LED灯173工作在恒定电流情况下，以解决上述直接串联或并联时所述LED灯173功耗大，且工作效率低的技术问题。
本实施例中，所述LED灯条171的数量可以根据实际设计需求进行设置，本实施例对此不作具体限制。作为一种实施方式，所述LED灯条171可以设置16个。可选地，所述16个LED灯条171之间相互平行，且相邻的LED灯条171之间的间距相等，从而实现所述LED灯条171的均匀排列。
进一步地，所述LED灯条171的具体结构请参阅图4和图5，所述LED灯条171上均匀设置有多个LED灯173。本实施例中，作为一种优选的实施方式，每个LED灯173的形状大小可以设置为相同，相邻的LED灯173之间的间距相等。此外，在本实施例中，相邻的LED灯条171上的每个LED灯173为一一对应关系。请结合图2，设置上述一一对应关系具体可以为，所述多个LED灯条171平行排列后，相邻的LED灯条171上每对对应的LED灯173之间的连线互相平行，进一步地，作为一种优选的实施方式，相邻的LED灯条171上每对对应的LED灯173之间的连线平行且可以垂直于所述LED灯条171的延伸方向。
进一步地，所述LED光源模组170与所述灯箱支架110之间的一种固定方式请参阅图7。多个所述LED光源模组170可以呈矩阵形式排列，并且任意两个所述LED光源模组170中的所述LED灯条171可以相互平行，也就是说，所述LED灯箱100中的所述LED灯条171均可以相互平行。这样，能够布置数量较多的所述LED光源模组170，使所述LED灯箱100包括较多的LED灯173，提高所述LED灯箱100的灰度等级，使所述LED灯箱100颜色丰富、色彩艳丽。
每个所述LED光源模组170可以包括两个所述灯条PCB连接件172，每个所述LED光源模组中的两个所述灯条PCB连接件172垂直所述LED灯条171设置，两个所述灯条PCB连接件172相互间隔。
相邻两个所述LED光源模组170中的所述灯条PCB连接件172通过电源线174和/或信号线175电性连接。可选地，每个所述LED光源模组170中的一个所述灯条PCB连接件172采用所述电源线174与相邻的所述LED光源模组170中的一个所述灯条PCB连接件172电性连接，每个所述LED光源模组170中的另一个所述灯条PCB连接件172采用所述信号线175与相邻的所述LED光源模组170中的另一个所述灯条PCB连接件172电性连接。这样，能够使所述控制器150对各个LED灯173的明暗灵活控制，使LED灯箱100呈现丰富多彩的动感效果。
所述LED灯箱100还可以包括金属丝180和卡扣181，所述金属丝180沿与所述LED灯条171的延伸方向设置在所述LED光源模组170上并与所述灯箱支架110相对的两端固定连接，所述卡扣181设置在所述金属丝180上并与所述灯条PCB连接件172卡接固定。
本实施例中，上述金属丝180可以是，但不限于铁丝、铜丝、钢丝、镍丝等。优选地，所述金属丝180可以采用钢丝。
可选地，作为本实施例的一种实施方式，所述电源线174可以采用防呆式双端连接线，所述信号线175可以采用绝缘位移连接器与灰排线的组合。
进一步地，所述LED光源模组170与所述灯箱支架110之间的另一种固定方式请参阅图6，所述LED灯箱100还可以包括金属管190和磁铁191。可选地，在本实施例中，所 述金属管190可以沿与所述LED灯条171延伸方向设置在所述LED光源模组170上并与所述灯箱支架110相对的两端固定连接，所述磁铁191设置在所述金属管190上并与所述灯条PCB连接件172磁性贴合，从而可以实现对所述LED光源模组170的固定。
本实施例中，上述金属管190可以是，但不限于钢管、铁管、铜管等。优选地，为了保证对所述LED光源模组170固定的可靠性，所述金属管190可以采用镀锌钢管，所述镀锌钢管可以为表面有热浸镀或电镀锌层的焊接钢管。其中，镀锌可增加钢管的抗腐蚀能力，从而延长使用寿命，保证对固定的可靠性。
相应地，在本实施例中，上述磁铁191可以采用永久性磁铁作为磁力来源。
容易理解的是，所述LED光源模组170固定安装在所述灯箱支架110上的方式还有很多，例如：在所述灯箱支架110上设置卡扣，将所述LED光源模组170卡接固定在所述灯箱支架110上；或者，在所述灯箱支架110的相对两侧设置卡槽，所述LED光源模组170的相对两端可以滑入卡槽，实现固定连接。同理，所述灯条PCB连接件172还可以通过类似或其他方式固定安装在所述灯箱支架110上。
进一步地，为了防止所述LED灯箱100在实际运行时发出的光发送投射反应影响展示的视觉效果，请参阅图8，所述LED灯箱100还可以在所述灯箱支架110和所述LED光源模组170之间设置吸光层120，所述吸光层120上覆盖有吸光性材料，从而可以防止所述LED光源模组170产生映射和大块的耀斑和反光，影响所述LED灯箱100的视觉效果。
本发明较佳实施例还提供一种显示装置，所述显示装置包括供电电源和上述的LED灯箱100，所述供电电源与所述LED灯箱100电性连接用于为所述LED灯箱100提供电源。
