背景技术
LED灯带(LED Strip),简称灯带,是将LED灯组装在导线或者带状线路板上,再套上PVC管或者采用设备直接成型。如果LED灯组装在带状柔性线路板上,可形成柔性LED灯带,此时LED灯一般采用贴片LED进行组装;如果LED灯组装在带状线路板硬板上,可形成硬性LED灯带,此时LED灯可以采用贴片LED进行组装,也可以采用直插LED进行组装。LED灯带与电源连接,发光时形状似一条光带,发光颜色多变、可调光、可控制颜色变化、可选择单色和RGB的效果,带给环境多彩缤纷的视觉效果。灯带已被广泛应用在建筑物、桥梁、道路、庭院、家具、汽车、标志等领域,用作装饰或照明。
近些年,灯带在可穿戴设备等与人们生活息息相关的产品上的应用日益增多,其作用也不仅仅局限于装饰或照明。例如,灯带可设置在鞋上,通过开关的闭合或打开,灯带接通电源或断开电源,灯带上的LED灯处于发光或不发光的状态,使得灯带呈现出亮暗的闪烁效果,增加鞋的美感,同时提升夜间行走的安全性;灯带还可设置在自行车尾部,同样通过开关的闭合或打开,灯带接通或断开电源,灯带上的LED灯处于发光或不发光的状态,使得灯带呈现出亮暗的闪烁效果,起到安全警示作用,提高夜间骑行的安全性;灯带还可以设置在凸出物体的边缘,通过灯带上LED灯的亮灭,提示行人注意避让。
目前这些应用中,灯带以闪烁模式呈现灯光变化,发光模式相对单一,并且线路结构较为复杂。

通过控制器在每条控制线L1、第二控制线L2、第三控制线L3和第四控制线L4上施加电压或者不施加电压(即处于断路状态),使得第一发光二极管D1、第二发光二极管D2、第三发光二极管D3、第四发光二极管D4、第五发光二极管D5、第六发光二极管D6、第七发光二极管D7和第八发光二极管D8处于导通、截止或断路三种状态之一。当发光二极管处于导通状态时,发光二极管发光;当发光二极管处于截止或断路状态时,发光二极管不发光。
控制器在第一控制线L1、第二控制线L2、第三控制线L3和第四控制线L4上施加的电压值位于第一发光二极管D1、第二发光二极管D2、第三发光二极管D3、第四发光二极管D4、第五发光二极管D5、第六发光二极管D6、第七发光二极管D7和第八发光二极管D8的工作电压数值范围内。

Figure PCTCN2019107794-appb-000001
优选地,发光二极管D1~D8的发光颜色相同,为红色、蓝色、绿色和黄色中的一种。
优选地,发光二极管D1~D8的发光颜色按照一定规律循环设置,这里的规律可以是颜色的变化规律,例如按照红绿蓝黄的顺序循环发光,或者按照红绿黄的顺序循环发光,或者按照红绿的顺序循环发光,或者按照红红绿绿的顺序循环发光等。
在本实施例中,任意两个发光二极管都不会同时发光,即如果有发光二极管发光,则其余发光二极管均不发光;并且第一发光二极管D1、第二发光二极管D2、第三发光二极管D3、第四发光二极管D4、第五发光二极管D5、第六发光二极管D6、第七发光二极管D7和第八发光二极管D8按顺序依次处于导通状态,整体呈现出依序接续式发光或依序跳跃式发光的效果,使得发光电路处于流水闪模式。
