本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
 本发明的最佳实施方式
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前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，本发明提供一种基于BLE蓝牙的LED灯音乐律动***，包括LED灯带1，以及与LED灯带1电连接的BLE蓝牙模块2；
所述BLE蓝牙模块2包括无线接收组件21，以及与所述无线接收组件21电连接的BLE蓝牙芯片22，所述BLE蓝牙芯片22还与所述LED灯带1电连接；
所述无线接收组件21接收外部音源设备（图未示）发送的LED闪烁图信息，并将所述LED闪烁图信息发送给所述BLE蓝牙芯片22，所述LED闪烁图信息为所述外部音源设备根据当前播放的歌曲的频谱信息所生成的；
所述BLE蓝牙芯片22根据所述LED闪烁图信息控制LED灯带1进行闪烁。
在实施时，所述外部音源设备通过蓝牙连接方式与所述LED灯音乐律动***通信连接，以所述外部音源设备为手机为例，手机蓝牙与所述LED灯音乐律动***建立通信连接，当手机播放音乐时，手机播放音乐的软件APP会获取正在播放的歌曲对应的频谱信息，然后根据所述频谱信息生成对应的LED闪烁图信息，再通过BLE连接实时发送给所述LED灯音乐律动***的BLE蓝牙模块2，所述BLE蓝牙模块2中的无线接收组件21接收到所述LED闪烁图信息后发送给BLE蓝牙芯片22，所述BLE蓝牙芯片22根据所述LED闪烁图信息控制LED灯带进行闪烁，所述BLE蓝牙模块2设于外壳4的中空腔室41内。
BLE在两个设备的连接中使用了跳频机制。两个设备使用特定的信道发送和接收数据，然后过一段时间后再使用新的信道（BLE协议栈的链路层处理信道的切换）。两个设备在切换信道后发送和接收数据称为一个连接事件。尽管没有应用数据被发送和接收，两个设备仍旧会交换链路层数据来维持连接。这个连接间隔就是这个两个连接事件的之间的时间间隔。间隔以1.25ms为单元，连接间隔的范围的6-3200既7.5ms-4s（4000ms）之间。由此可以看出：间隔小，适用于那些需要快速反应的任务。
实际使用时会出现掉帧现象，表现为LED闪烁不连续。因此需要将BLE的跳频的时间间隔设置比较小的值。以达到LED灯带1闪烁及时连续的效果。
本实施例通过采用BLE蓝牙模块2与LED灯带1电连接，所述BLE蓝牙模块2包括无线接收组件21和BLE蓝牙芯片22，通过无线接收组件21无线接收外部音源设备发送的LED闪烁图信息，所述LED闪烁图信息为所述外部音源设备根据当前播放的歌曲的频谱信息所生成的，然后BLE蓝牙芯片22根据所述LED闪烁图信息控制LED灯带1进行闪烁，使LED灯带1发出与所述外部音源设备播放的歌曲对应配合的灯光效果；通过采用无线连接的方式，能有效避免外部音源设备与LED灯带1之间的布线限制，提高用户体验。
在一个可选实施例中，所述BLE蓝牙芯片为BLE蓝牙单模芯片。
蓝牙低能耗(Bluetooth Low Energy，简称BLE)技术是低成本、短距离、可互操作的鲁棒性无线技术，工作在免许可的2.4GHz ISM射频频段。蓝牙低能耗技术采用可变连接时间间隔，这个间隔根据具体应用可以设置为几毫秒到几秒不等。另外，因为BLE技术采用非常快速的连接方式，因此平时可以处于“非连接”状态（节省能源），此时链路两端相互间只是知晓对方，只有在必要时才开启链路，然后在尽可能短的时间内关闭链路。
蓝牙低能耗技术的架构共有两种芯片构成：单模芯片和双模芯片。蓝牙单模器件是蓝牙规范中新出现的一种只支持蓝牙低能耗技术的芯片——是专门针对ULP操作优化的技术的一部分。蓝牙单模芯片可以和其它单模芯片及双模芯片通信，此时后者需要使用自身架构中的蓝牙低能耗技术部分进行收发数据。单模芯片可以用单节钮扣电池(如3V、220mAh的CR2032)工作很长时间(几个月甚至几年)。
本实施例通过将BLE蓝牙芯片采用BLE蓝牙单模芯片，能有效降低能源消耗，减少使用成本，提高用户体验。
在一个可选实施例中，还包括电源组件3，该电源组件3分别为所述BLE蓝牙模块2和LED灯带1供电。
在实施时，所述电源组件3包括可充电电池31和/或外部供电接口模块32，所述可充电电池31和外部供电接口模块32均与所述BLE蓝牙模块2电连接。所述外部供电接口模块可以设计成采用标准的MICRO USB 接口，可以使用手机通用的充电器，或者用充电宝供电，使用方便。
另一方面，如图2所示，本发明还提供一种基于BLE蓝牙的LED灯音乐律动控制方法，应用于LED灯音乐律动***中，包括：
步骤S1，接收外部音源设备通过无线方式发送的LED闪烁图信息，所述LED闪烁图信息为所述外部音源设备根据当前播放的歌曲的频谱信息所生成的；
步骤S2，根据所述LED闪烁图信息控制LED灯带进行闪烁。
在实施时，所述LED灯音乐律动***包括LED灯带以及与LED灯带电连接的BLE蓝牙模块，所述BLE蓝牙模块包括无线接收组件以及BLE蓝牙芯片，所述BLE蓝牙芯片采用BLE蓝牙单模芯片，所述BLE蓝牙芯片通过无线接收组件接收外部音乐设备通过无线方式发送的LED闪烁图信息，具体地，当外部音源设备播放音乐时，外部音源设备播放音乐的软件会获取正在播放的歌曲对应的频谱信息，然后根据所述频谱信息生成对应的LED闪烁图信息，外部音源设备与BLE蓝牙模块2通过BLE连接，实时将所述LED闪烁图信息发送给所述LED灯音乐律动***的BLE蓝牙模块2，然后BLE蓝牙芯片再根据所述LED闪烁图信息控制LED灯带进行闪烁，产生与外部音源设备播放的歌曲对应配合的灯光效果。
在一个可选实施例中，如图3所示，所述根据所述LED闪烁图信息控制LED灯带进行闪烁的步骤之后包括：
步骤S3，歌曲播放完毕后控制BLE蓝牙芯片处于休眠状态。
当外部音源设备的一首歌曲播放完毕或者停止播放时，预设时间间隔内，BLE蓝牙芯片通过无线接收组件没有接收到外部音源设备发送的信号，此时所述BLE蓝牙芯片将进入休眠状态以减少能源消耗，减少使用成本。
在一个可选实施例中，如图4所示，所述接收外部音源设备通过无线方式发送的LED闪烁图信息的步骤之前包括：
步骤S4，接收外部音源设备发送的通信连接请求，并根据所述通信连接请求建立与外部音源设备的通信连接。
在实施时，外部音源设备的蓝牙设配器与所述BLE蓝牙模块2连接，BLE在两个设备的连接中使用了跳频机制。两个设备使用特定的信道发送和接收数据，然后过一段时间后再使用新的信道（BLE协议栈的链路层处理信道的切换）。两个设备在切换信道后发送和接收数据称为一个连接事件。尽管没有应用数据被发送和接收，两个设备仍旧会交换链路层数据来维持连接。这个连接间隔就是这个两个连接事件的之间的时间间隔。间隔以1.25ms为单元，连接间隔的范围的6-3200既7.5ms-4s（4000ms）之间，所以对于BLE的跳频的时间间隔设置比较小的值，以达到LED闪烁及时连续的效果。通过在传输数据之前建立外部音源设备与BLE蓝牙模块2的通信连接，能有效提高信息传输的可靠性和安全性。
再一方面，如图5至图7所示，本发明还提供一种基于BLE蓝牙的LED灯音乐律动控制装置，包括：
无线接收单元100，用于接收外部音源设备发送的LED闪烁图信息，所述LED闪烁图信息为所述外部音源设备根据当前播放的歌曲的频谱信息所生成的；

本实施例通过设有无线接收单元100以接收外部音源设备通过无线方式发送的LED闪烁图信息，具体地，当外部音源设备播放音乐时，外部音源设备中用于播放音乐的软件会获取正在播放的歌曲对应的频谱信息，然后根据所述频谱信息生成对应的LED闪烁图信息，然后实时将所述LED闪烁图信息发送给无线接收单元100，无线接收单100再将所述LED闪烁图信息发送给BLE蓝牙单元200，所述BLE蓝牙单元200根据LED闪烁图信息控制LED灯带进行闪烁，产生与外部音源设备播放的歌曲对应配合的灯光效果，采用无线方式能减少外部音源设备与LED灯带之间的布线限制，提高用户体验。
在一个可选实施例中，还包括：
休眠单元300，用于在歌曲播放完毕后控制BLE蓝牙芯片处于休眠状态。
在实施时，通过休眠单元300控制BLE蓝牙芯片在歌曲播放完毕或者暂停播放时进入休眠状态，当外部音源设备再次播放歌曲，或者暂停播放之后再次继续播放时，无线接收组件接收到外部音源设备发送的LED闪烁图信息，从而唤醒休眠中的BLE蓝牙芯片进入工作状态，减少能源消耗。
在一个可选实施例中，还包括：
通信建立单元400，用于接收外部音源设备发送的通信连接请求，并根据所述通信连接请求建立与外部音源设备的通信连接。
在实施时，外部音源设备广播通信连接请求，通信建立单元400接收所述通信连接请求后建立无线接收单元100与外部音源设备之间的通信连接，使得外部音源设备的蓝牙适配器连接无线接收单元100实现无线通信功能，减少外部音源设备与LED灯带之间的连线布线限制。
具体地，所述外部音源设备的蓝牙设配器与本发明基于BLE蓝牙的LED灯音乐律动控制装置通信连接，BLE在两个设备之间的连接中使用了跳频机制。两个设备使用特定的信道发送和接收数据，然后过一段时间后再使用新的信道（BLE协议栈的链路层处理信道的切换）。两个设备在切换信道后发送和接收数据称为一个连接事件。尽管没有应用数据被发送和接收，两个设备仍旧会交换链路层数据来维持连接。这个连接间隔就是这个两个连接事件的之间的时间间隔。间隔以1.25ms为单元，连接间隔的范围的6-3200既7.5ms-4s（4000ms）之间，所以对于BLE的跳频的时间间隔设置比较小的值，以达到LED闪烁及时连续的效果。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
