进一步的，还可根据预设规则切换工作LED模组，所述预设规则包括：工作LED模组工作时间达到预设时间值，切换工作LED模组；或电源断开重新连接，切换工作LED模组。可采用如下方式：判断当前工作LED模组的工作时间是否达到预设时间值，若达到预设时间值，则切换工作LED模组，即让LED模组轮流工作，从而减少同一个LED模组的负荷，延长全部LED模组的寿命。预设规则亦可以是在每一次电源断开重新连接时，切换工作LED模组，如此刻是LED模组1工作状态，切断电源重新接通电源，则优选为启动LED模组2工作。如此轮流工作，亦可以减少同一个LED模组的负荷，延长全部LED模组的寿命。
在其它实施方式中，亦可以根据实际情况预设其它各种各样的预设规则，并不做限制。
进一步的，所述“根据预设规则切换工作LED模组”前，还包括步骤：采集待切换的LED模组的电参数，根据预设参数值判断所述电参数是否合格，若所述电参数不合格，轮换至其它待切换的LED模组。可采用如下方式：如：预将LED模组1切换至LED模组2工作前，采集LED模组2的电参数，根据 预设参数值判断所述电参数是否合格，若所述电参数不合格，则跳过切换至LED模组2，可轮换至LED模组3或者是LED模组4，若其它LED模组均损坏或异常，则不进行切换，仍然保持当前LED模组1工作。
进一步的，若所述电参数不合格，获取损坏LED模组的信息，发送损坏LED模组的信息至终端。可采用如下方式：若所获取到的电参数不合格，则单片机获取损坏LED模组的信息，发送损坏LED模组的信息至终端。在本实施方式中，终端可以为智能手机、平板电脑、台式PC、笔记本电脑、PDA、智能手表等等具有即时通讯功能或者安装有即时通讯软件或app的智能设备。可优选发送至维修人员的智能手机上，提醒维修人员哪些LED模组已损坏，维修人员根据获取到的信息可合理安排时间针对性进行维修，大大节约人力物力。
在本实施方式中，LED模组损坏或异常时，亦可以通过指示灯按特定频率闪烁告知维修人员，亦可以通过蜂鸣器提示，亦可以是指示灯与蜂鸣器同时提示。
进一步的，在单片机判断LED模组电参数不合格时，会存储对应损坏或异常的LED模组的信息，待切换工作LED模组时，跳过损坏LED模组。通过单片机对异常LED模组的信息的存储，在下一次要切换工作模组时，单片机就直接跳过这些损坏的LED模组，避免一些无用操作。
