Description

一种可多方向弯曲的LED灯带
本申请要求于2019年11月13日提交中国专利局、申请号为201911105070.2、发明名称为“一种可多方向弯曲的LED灯带”的中国专利申请的优先权，上述专利的全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示领域，特别涉及一种可多方向弯曲的LED灯带。
背景技术
如图1至图4，示出了现有的一种柔性灯带。其中，图1示出了用软性弹性塑料或硅胶制作而成的芯线1’，芯线1’内预置了至少两条与灯带等长的主导线20’、21’，该两主导线处与同一水平线上，并与灯带表面平行；并在中间位置并预留了与芯线等长的芯线槽8’；图2示出了一个灯串3’，其包括有光源5’、电子元器件6’和连接线7’，所述灯串3’会嵌入图1中的芯线槽8’内，然后将灯串的首尾与芯线1’的主导线20’、21’并联。如图3，通常一条灯带由若干个灯串单元组成。在图3基础上，再包覆一层软性弹性塑料或硅胶4’就形成了一条完整的灯带，如图4所示。
但是现有的这种灯带，其只能在一个方向上可以弯曲(如图5)。而如果在另一个方向上进行弯曲时，其一根主导线20’将受到压缩，另一根导线21’将受到拉长，虽然弹性塑料或硅胶可以被拉伸或压缩，但灯带产生不了足以使金属导线缩短和拉长的力；所以，金属导线的这种布置结构阻止了灯带向这个方向的弯曲。如图6和图7所示，当灯带按照图6的弯折方向进行弯折时，其中，理论上，导线21’会被拉长(见虚线L1)，而导线20’会被压缩(见虚线L2)，如果L1或L2超过了导线拉长或压缩极限，或者这个方向的弯曲力足够大时，导线就会存在被拉断的风险。故现有的这种灯带，大大限制了其使用场景。
发明内容
本发明所要解决的技术问题在于，提供一种可多方向弯曲的LED灯带，实现灯带的多方向弯曲，扩大产品的应用范围和使用的便利性。
为了解决上述技术问题，本发明的实施例提供一种可多方向弯曲的LED灯带，其包括：

同时，在FPC板中，也将部分结构设置为波浪曲线结构，进一步提高了灯带的抗弯折能力。
附图说明

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的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本发明保护的范围。
在此，还需要说明的是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
如图8所示，示出了本发明提供的一种可多方向弯曲的LED灯带的第一实施例，同时一并参照图9至图12所示。在该实施例中，所述可多方向弯曲的LED灯带包括：
芯线1，在本实施例中，其横截面为大致凹形，可以理解的是，在其他实施例中不限于此；其中间具有一沿灯带方向设置的芯线槽8，在所述芯线槽8两侧的芯线中设置有至少两条主导线，在本实施例中示出了两条主导线20、21，可以理解的是，在其他的实施例中也可以采用两条以上的主导线；
多个LED灯串3，间隔设置于所述芯线槽8中，其至少包含LED光源5、电子元器件7和连接线7，各LED灯串的首尾连接线7并联在所述两条主导线20、21之间；在本实施例中，所述LED灯串3的结构可参照图2所示，其与主导线之间的连接可参照图3所示；
绝缘包裹层4，包裹在所述芯线1之外；
本实施例与图4的现有技术的主要区别在于，所述两条主导线20、21为波浪曲线结构，具体地，可参照图8所示。为了便于观察，在后续的图9至图11中只示出了一条波浪曲线结构，可以理解的是，此仅为示意，在实际产品中，另一条主导线也同样是采用波浪曲线结构。
在本实施例中，所述芯线1以及绝缘包裹层4可以采用诸如软质塑胶材料或硅胶材料。所述主导线20、21可以采用铜、铝、钢或上述材料的合金制成。
一并参照图10至图12，从中可以看出，该结构的灯带可实现多方向的弯曲，例如按照图10和图11的弯曲方向弯折，其中两个主导线的拉伸示意图如图12所示，由于设置了波浪曲线式导线结构，满足了灯带在任意方向弯曲时，随着弹性塑胶或硅胶的拉伸和压缩，主导线20、21象弹簧一样拉长和缩短，而不会阻止灯带的弯曲变形。
如图13所示，示出了本发明供的方向弯曲的LED灯带另一个实施例中灯串的结构示意图。在本实施例中，其与图9示出的结构的区别在于，其中， 所述多个灯串设置于FPCB板上。具体地，所述FPCB板包括多个间隔设置的器件焊接区30，以及在相邻器件焊接区30之间的连接区31；其中，器件焊接区30上焊接有贴片LED光源5或/贴片电子元器件6，连接区31上形成有连接各贴片LED光源5以及贴片电子元器件6之间的连接线7。在一个例子中，器件焊接区30为矩形，相邻器件焊接区30之间的连接区31至少为一长条形(例如在其他的例子中，可以是两条或以上)，其宽度小于所述器件焊接区30的宽度。
在一个具体的例子中，所述连接区31为波浪曲线结构，其弯曲方向与所述两条主导线20、21的波浪曲线结构相同。
在本实施例中，FPCB板中形成的灯串同样会与弯曲的主导电实现并联。其他结构与前述图9中示出的结构相同，在此不进行详述。
通过FPCB使制作灯串变得更加简单，并可以设计复杂的电路；另外，通过将FPCB的一部分设置为波浪曲线结构，进一步提高了灯带的抗弯折能力。
实施本发明实施例，具有如下有益效果：
实施本发明所提供的一种可多方向弯曲的LED灯带，其芯片中的两条主导线采用波浪曲线结构，可以提高灯带抗弯折的能力，使其可以实现多方向弯曲；
同时，在FPC板中，也将部分结构设置为波浪曲线结构，进一步提高了灯带的抗弯折能力。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
