相邻两粒 LED交替亮灭 （L1频闪 3次后灭掉， 同时 L2从灭到频
8
闪 3次； 此功能反复循环） 本实施例公开一种使用本发明 LED灯饰控制器 10的 LED灯饰。 如图 7、 8、 11所示， 本实施例公开的 LED灯饰包括无级 LED灯条 60， 无级 LED灯条 60包括并联灯串 50， 并联灯串 50包括第一信号线 41和第 二信号线 42， 第一信号线 41和第二信号线 42之间连接有两个以上的 LED 灯珠， 至少一个 LED灯珠的正极连接第一信号线 41， 负极连接第二信号线 42;至少一个 LED灯珠的负极连接第一信号线 41，正极连接第二信号线 42， 第一信号线 41和第二信号线 42分别耦合到 LED灯饰控制器 10的信号插座。 正极连接第一信号线 41的 LED灯珠组成第一灯组 Ll， 正极连接第二信号 线 42的 LED灯珠组成第二灯组 L2 ,第一灯组 L1和第二灯组 L2并联设置； 由于第一灯组 L1和第二灯组 L2连接方式刚好相反， 因此在实际应用只有 一个灯组发亮， 只要在同一时间只有一条信号线有脉宽调制控制的驱动信 号， 就能保证一个灯组发亮， 另一个灯组熄灭。 这样只要脉宽调制控制的 驱动信号交替接入第一信号线 41和第二信号线 42就能实现两种不同灯组 的交替显示， 而通过调节脉宽调制控制的驱动信号的占空比就能调节当前 显示灯组的显示亮度， 实现自已所要的灯串显示效果。
并联灯串 50可以有多个， 每个并联灯串 50之间串联设置， 每个并联 灯串 50的第一信号线 41跟前一级并联灯串 50的第二信号线 42或 LED灯 饰控制器 10的信号插座耦合;每个并联灯串 50的第二信号线 42跟后一级 并联灯串 50的第一信号线 41或 LED灯饰控制器 10的信号插座耦合。
参见图 9、 10， 每个并联灯串 50有十个 LED灯珠， 即每个灯组有五 个 LED灯珠， 每个并联灯串 50头尾依次串接， 形成无级 LED灯条， 最终 无级 LED灯条最前端并联灯串 50的头部和最末端并联灯串 50的尾部共计 两根信号线连接到 LED灯饰控制器 10的信号插座。
本发明 LED灯饰的最终效果图参见图 11。 实施例三
本实施例公开一种本发明 LED灯饰的驱动方法， 包括歩骤：
A、 将脉宽调制控制的驱动信号接入第一信号线；
B、 将脉宽调制控制的驱动信号接入第二信号线； 返回歩骤八。 为了增强显示效果， 还可以在歩骤 A和歩骤 B之间增加歩骤 A1 : 控 制脉宽调制控制的驱动信号断开后返回歩骤 A, 等返回的次数达到 N次， 转歩骤 B; 歩骤 B中包括： 控制脉宽调制控制的驱动信号断开后， 再将脉 宽调制控制的驱动信号接入第二信号线， 等重复的次数达到 N次， 返回歩 骤 A。 其中 N为自然数。 增加歩骤 A1后可以让同一灯组闪烁几次后再切 换到其他灯组进行显示，这样就丰富了显示效果，拓展了产品的应用范围。
参见图 6， LED灯饰的显示模式可以预先写入到本发明的 LED灯饰控 制器的单片机中，如图中的子程序 1〜8所示，每个子程序对应一种显示模 式， 程序执行时先判断模式控制按钮是否按下来， 然后根据键值来判断具 体需要执行哪个子程序。 键值可以跟按键的次数关联， 也可以跟按键的持 续时间关联。 本实施例的显示模式参见表 1。
以上内容是结合具体的优选实施方式对本发明所作的进一歩详细说 明， 不能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术 领域的普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若 干简单推演或替换， 都应当视为属于本发明的保护范围。
