具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
图1示出了本发明的一实施例中的LED灯带的结构示意图，该LED灯带的扭弯性能增强，使灯带立体造型时更加便捷，还不会遮挡发光源发出的光线。其包括柔性电路板1、导线、至少一个LED灯带单元2和第二连接装置3 。
在一些实施例中，该柔性电路板1作为LED灯带的主要支撑部件，用于供电子元器件安装和形成特定形状的连接组件。柔性电路板1本身的形状和长度均可以根据产品的规格来进行调节的。
可以理解地，本发明的LED灯带所需要的柔性电路板1整体上呈条状，并且为了便于裁剪出需要的灯带的长度，该柔性电路板1可以做到50米、100米或者更长。
进一步地，因该柔性电路板1上的电子元器件一般需要避免直接裸露在空气中，则该柔性电路板1的外部包覆有透明外壳。该透明外壳为PVC材料制成的软质透明外壳。由于PVC材料的特殊性能，即使在安装过程中发生短路，也不会造成火宅或其他安全隐患。
更进一步地，该柔性电路板1的背面还设置有背胶6，用于将LED灯带贴装在物体的表面。可以理解地，要将LED灯带贴装在物体的表面的方式有很多种，例如，固定钉、双面胶等。在本发明的一些实施例中，背胶6为优选地实施方式。
在一些实施例中，该导线设置在该柔性电路板1上，用于串联或并联多个LED灯带单元2。该导线串联多个LED灯带单元2时，导线的数量最少为一根。该导线并联多个LED灯带单元2时，导线的数量最少为两根。
参阅图7，可以理解地 ，为了便于LED灯带剪裁后各LED灯带单元2之间互不影响，可以优选地采用两根导线并联多个LED灯带单元2的形式。本发明的一些实施例中就是采用了两根导线并联多个LED灯带单元2的方式，且两根导线之间的电压为DC12V。
参阅图6，进一步地 ，当LED灯带的长度较短、LED灯带单元2较少时，则可以采用通过一根导线串联多个LED灯带单元2的方式进行设计和生产。因为这样的情况下采用串联的方式不仅降低了加工成本，还进一步保证了LED灯带使用的稳定性。
更 进一步地，导线一般沿该柔性电路板1的长度方向布置，为了便于布线和加工，导线的形状可以做成片状。当然，采用常见的圆柱状的导线也是可以的。
在一些实施例中，至少一个LED灯带单元2连接在该导线上，
该LED灯带单元2包括至少两个安装部、至少一个第一连接装置以及至少两个贴片式LED灯22。
至少一个第一连接装置将至少两个安装部可在同一个平面上相对转动地连接在一起，此处的同一平面内相对转动即一个安装部可相对相邻的另一个安装部顺时针转动或逆时针转动。
可以理解地，同一平面为三维空间内的任一平面，则在三维空间内任一平面内相对转动的两安装部使得LED灯带的三维扭弯能力增强，从而得到很好的三维灯光效果。
参阅图2，上述的安装部 和 第一连接装置均形成在该柔性电路板1上。
柔性电路板1包括至少两段安装带24和至少一段第一连接部21a、21b、21c。
至少两段安装带24形成至少两个安装部，至少一段第一连接部21a、21b、21c形成至少一个第一连接装置。
第一连接部21a、21b、21c的宽度小于安装带24的宽度。宽度较小的第一连接部21a、21b、21c 不仅 使得LED灯带 的扭弯性能增强，而且使得LED灯带 在弯曲扭转时造成的形变不会阻挡LED光源发出的光。
在一些实施例中，本发明的LED灯带的 第一连接装置 优先地 采用了第一连接部21a、21b、21c的结构。可以理解地，能实现上述效果的第一连接部21a、21b、21c的结构多种多样 。 下面介绍一下本发明的一些实施例中的第一连接装置采用第一连接部21a、21b、21c的情况。
参阅图3，第一连接部21a包括位于柔性电路板1两侧的缺口和两缺口之间的U形连接件21a1。且相邻的该U形连接件21a1的开口方向朝向相反。
可以理解地，根据不同型号、不同长度的LED灯带，U形连接件21a1的开口方向及相邻的该U形连接件21a1的开口方向的朝向均能采用其他可行的方案，只要能便于LED灯带的弯折扭转即可。
参阅图4，第一连接部21b均包括位于柔性电路板1一侧 或两侧 的缺口和位于柔性电路板1另一侧 或位于两 所述第二缺口之间的条形连接件21b1。且缺口在柔性电路板1所在的平面内均呈长方形，相邻的缺口的开口方向朝向相反 或相同 。可以理解地，此处的缺口的形状还可为其他多边形的形状或不规则的形状等。
参阅图5，第一连接部21c均包括位于柔性电路板1两侧的缺口和两缺口之间的圆片状连接件21c1。且圆片状连接件21c1的两连接端21c3均呈带状、扁平状或柱状。另外，圆片状连接件21c1上均设置有固定孔21c2。
可以理解的地，此处的连接件的形状还可采用其他常见的形状，例如，方形片状连接件或多边形片状连接件等。
进一步地，该固定孔21c2设置在圆片状连接件21c1的中心位置，便于加工和使用。使用该固定孔21c2可以有效地、省力地对弯折后的LED灯带进行固定。
另外，第一连接部为呈螺旋状的连接带。可以理解地，此处的呈螺旋状的连接带的形状如同座机电话话筒那段的连接线的形状，呈螺旋状的连接带的形状特征决定了其具有较高的柔韧性与延展性，使得LED灯带能进行大角度的弯曲扭转。并且，呈螺旋状的连接带弯曲扭转时不会使得LED灯带的弯曲部出现大的耸角，即不会出现阻挡光源发出的光的情况，在增强了LED灯带的扭弯性能的同时，还使得LED灯带发出的光更加的均匀。上述第一连接部21a、21b、21c的 结构 均能使得LED灯带在 同一 水平面内 的扭弯性能增强 ，但第一连接部21a、21b、21c的 结构 不局限于上述的 结构 ，只要是能实现LED灯带在同一水平面内的扭弯性能得到增强的第一连接部21a、21b、21c的结构均在本发明的保护范围内。
另外，第一连接装置除了采用第一连接部21a、21b、21c 的结构 外，还可以采用金手指连接器，该金手指连接器上设置有插槽，该金手指连接器的两端的柔性电路板1插入该插槽内。金手指连接器自身可以进行弯折和旋转，则LED灯带的扭弯性能得到了增强。
在一些实施例中，至少两个贴片式LED灯22分别设置于至少两个安装部上。该贴片式LED灯22作为LED灯带的光源。
可以理解地，至少两个贴片式LED灯22发出的光的颜色和颜色的组合可根据LED灯带的使用环境而定。该贴片式LED灯22的合理的布置和选择可进一步提升了LED灯带的装饰作用。
进一步地，构成LED灯带单元2的贴片式LED灯22的数量是可选择的，本发明的一些实施例中采用的是将三个贴片式LED灯22串联后再与一限流电阻23串联。
在一些实施例中，该限流电阻23也安装在该安装部上，用于保护LED灯带单元2不受损坏。
可以理解地，限流电阻23可以串联在电路中，也可以不串联在电路中，需根据具体的产品规格来决定是否设置该限流电阻23。
在一些实施例中，LED灯带包括多个LED灯带单元2以及以及将该多个LED灯带单元2串联在一起的多个第二连接装置3。
在一些实施例中，该第二连接装置3也形成该柔性电路板1上， 即该 柔性电路板1包括多个第二连接带，多个第二连接带形成多个第二连接装置3。
可以理解地，当第二连接装置3采用第二连接带的结构时，该第二连接带的宽度可以小于或等于该柔性电路板1的宽度。优选地，本发明中的LED灯带的第二连接带的宽度与柔性电路板1的宽度保持一致，便于加工和生产。
进一步地，因LED灯带可裁剪成任意的长度，裁剪时需要有一个裁剪的标识，则该第二连接装置3上均设置有剪刀标识。
可以理解地，当第二连接装置3采用第二连接带的结构时， 第二连接带上均设置有剪刀标识。 该剪刀标识便于安装操作人员进行准确裁剪，减少失误，提高工作效率。
进一步地 ，裁剪的标识还可以采用常见的便于理解的图案，例如，虚线等。
更进一步地，因将LED灯带裁剪后还需接入外接电源通电后发光使用，则该第二连接装置3上均设置有用于接入外接电源线5的焊盘。可以理解地，当第二连接装置3采用第二连接带的结构时， 焊盘设置在第二连接带上。
在一些实施例中 ，为了防止通电后出现漏电或短路的现象，该第二连接装置3的外部均包覆有绝缘件4。
可以理解地，当第二连接装置3采用第二连接带的结构时， 该第二连接带的外部均包覆有绝缘件4。 该绝缘件4可采用常见的绝缘部件，例如，绝缘套、热缩套管等。
本发明的一些实施例中，该绝缘件4优选地采用热缩套管。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改、组合和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
