Description

基于音频的灯具控制***、装置和控制方法及其应用 技术领域
本发明涉及灯具控制领域，更进一步，涉及一基于音频的灯具控制***、装置和控制方法及其应用。
背景技术
声控灯光技术，特别是音乐控制灯光闪烁已越来越多地应用在人们的生活中。其将音乐声响与灯光亮度及其色彩相结合，使音乐的旋律伴随以亮度、颜色和图案不断变换的灯光，使人的视觉的和听觉结合在一起获得综合的艺术享受。
目前市场上常见的根据音乐的播放控制灯具颜色的方式主要有两种。其中一种是音乐播放台通过有线的方式连接各个灯具，把根据音乐变化的控制指令通过有线的方式发送给灯具。另一种常见控制方式是，将扬声器和灯具集成在一起，通过蓝牙无线传输音频至灯具端，在灯具端对传输过来的音频进行采样处理后控制灯具。
这两种控制方式各自都存在弊端。首先，第一种有线控制方式，音乐播放器需要不同的灯具进行连接，这使得的布线成本和灯具价格成本都比较昂贵。
其次，第二种控制方式，虽然可以采用无线的控制方式，可是这种控制方式中可以控制的灯具数量及其有限，一般不会超过4个。
此外，第二种控制方式中，由于音响与灯具集成，因此受限于灯具的尺寸，使得音响效果较差，而且使用、安装及其不方便。
还值得一提的是，现有的两种控制方式，音乐设备和灯具之间，或者说播放的音乐的与灯具之间都存在一定的对应关系，也就是说，可以控制灯光的音乐是预定的，且是有限量的，并不能随意通过各种喜欢的音乐来控制灯光，这种控制方式使得声控灯具的应用范围较窄，只能应用于一些较大型的公共场所，不适应现代多样化的生活方式。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
如图1至图5所示，是根据本发明的第一个优选实施例的基于音频的灯具控制***。所述灯具控制***100可以通过音乐控制灯具的工作，从而使得灯具根据音乐的变化节奏而有规律的变化。所述灯具控制***100独立于音响设备1而存在，可以接受各种音响设备的音乐输出来控制灯具的工作。所述灯具控制***100独立于灯具2而存在，可以应用于各种应用设备，如手机、台式电脑、平板电脑、可穿戴设备等，或者被实施为独立的控制装置。
本领域的技术人员应当理解的是，音乐，通常情况音乐是指反映人类生活情感的艺术，因此可能限于某一波段，而本发明旨在于通过各种音频信号来控制灯光的变化，也就是说，输入各种音频信号都可以去控制灯光，而不是限定于具有感情色彩或者某一特定波段的声音。因此，本发明的中的“音乐”不限于通常情况的音乐。
根据本发明的这个优选实施例，所述基于音频的灯具控制***100包括一音频信号采集单元110、一处理单元120、一发送单元130和一控制单元140。
所述灯具控制***100用于控制一灯具2的工作。在一实施例中，所述灯具包括多个彩灯，通过所述灯光控制***100控制所述多个彩灯的灯光色彩及明暗变化。
所述音频信号采集单元110采集用于控制灯具工作的音频信号。
值得一提的是，所述音频信号采集单元110可以采集各种音响设备1发出的音频信号，而不限于指定的音响设备或者指定的音乐，因此使得控制源更加广泛，控制类型更加多样化。音频信号采集过程独立于音响设备而存在，因此不受音响设备的限制，使得各种应用设备发出的音频信号都可以用于控制灯具，使得应用范围更加广泛，而不限于公共场所，举例地，可应用于KTV或普通家庭，降低了整个***的成本并可充分利用现有的音响***进行功能的扩充，保留原有的音 响***的音质。
还值得一提是，在本发明的一实施例中，所述音频信号采集单元110以无线的方式进行信号采集，而不需要像现有技术中通过信号线连接于音响设备或音乐源所在位置，从而避免了布线的烦琐过程，使得应用更加简便、降低安装成本。
在本发明的一实施例中，所述音频信号采集单元110包括一匹配模块111，使得所述音频信号采集单元110采集预定的音乐信号，排除非控制类的音频信号的干扰。也就是说，当外部的音频信号通过所述匹配模块111的匹配时，说明是需要控制灯具工作的音乐，所述音频信号采集单元110采集该音频信号，从而排除其他的音频的干扰、避免采集到错误的音频信息。
在本发明的一实施例中，通过麦克风采集外部的音频信号，从而控制灯具的工作，不需要音响设备与控制***直接连接。
所述处理单元120将所述音频信号采集单元110采集的音频信息进行处理，将音频信号转化为控制灯具工作的控制信号。
所述发送单元130发送所述处理单元120处理等到的控制信息至灯具端。
值得一提的是，在本发明的一实施例中，所述发送模块130以无线通信的方式传递信息于灯具控制端，从而使得灯具的控制于所述控制***100之间相互独立，使得控制更易于实现，且控制灯具的数量不受限制。
参照图4，在本发明的一实施例中，所述发送单元120包括一Zigbee模块和一WiFi模块，通过所述zigbee模块的AD口读取所述处理单元120得到的控制信息，通过Zigbee2.4G无线发送给所述灯具200，从而控制所述灯具200的工作。所述WiFi模块和所述Zigbee模块通过Uart(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)通信连接。通过所述WiFi模块可以接受外部设备的控制信息。举例地，通过手机控制灯光的工作，WiFi模块接受来自手机的控制信息或设置命令，并且把接收的命令解析后通过Uart口发送给Zigbee模块，然后通Zigbee2.4G无线发送给灯具，进行亮度或颜色的手动设置。
也就是说，在这里，所述灯具控制***100提供了两种控制方式，一种是所述灯具控制***100自动控制，另一种是通过外部其他设备间接地手动控制，这两种控制方式可以各自独立控制，也可以同时相互协调控制。这种可选择的控制方式，使得灯具的控制更加方便，而且更加人性化。用户可以根据自己的喜好搭配喜欢的音乐以及喜欢的灯光颜色组合。所述控制单元140可以接收多路控制信 号，从而可以以多种方式同时控制所述灯具。
更具体地，在本发明的一实施例中，所述灯具控制***被设置于一网关，所述网关采集当前环境中的音频数据，并计算出相应音频数据对应的RGB颜色，通过zigbee无线模块发送相关的颜色至RGB灯具端，灯具端接收到无线控制信号后，把相应的灯具设置成相关的颜色。手机通过WiFi连接网关上的WiFi节点，并通过安装在手机上的应用软件通过WIFI把控制命令发送给网关，网关把其中的调光或调色命令发送给灯具。
在本发明的一实施例中，所述灯具控制***100包括一电源单元，为所述音频信号采集单元110、所述处理单元120、所述发送单元130和/或所述控制单元140提供工作电源。在一实施例中，所述电源单元为适配器，提供***适宜的工作电压。更具体地，所述适配器供应所述网关适应电源。
所述控制单元140接收所述发送单元130发送的控制信息，控制所述灯具200的工作。
在本发明的一实施例中，所述控制单元140与所述灯具200相连接，对应控制所述灯具200。
参照图5，在本发明的一实施例中，所述控制单元140包括一AC/DC转换电路和一Zigbee模块，AC/DC转换电路输出一路恒压直流输出给3路LED恒流芯片供电，另外一路恒压小电流输出给Zigbee模块供电，Zigbee模块接收来自于网关的Zigbee 2.4G无线信号并通过PWM(Pulse Width Modulation,脉冲宽度调制)控制LED恒流芯片实现RGB灯的颜色和亮度的变化。
在这种实施方式中，所述发送单元130和所述控制单元140各自包括所述的Zigbee模块相对应，从而实现单元之间信息的无线传输。
如图6所示，是根据本发明的上述优选实施例的基于音频的灯具控制方法，所述控制方法以上述实施例的基于音频的灯具控制***为基础，所述方法1000包括如下步骤：
(A)采集音频信号；
(B)转换音频信号为灯光控制信号；和
(C)通过控制信号控制灯光。
一方面，所述基于音频的灯具控制方法中信号采集与音响设备相互独立，也就是说信号采集与音频信号源之间相互独立，因此各种音响设备发出的音频信号 都可以被采集来作为控制源，控制灯光的变化，不同于现有技术中通过指定设备控制点方式。更进一步，所述灯具控制方法以无线的方式接受各种音响设备的发出的音频信号，因此不需要连接线，也不同于现有技术中有线传输的方式。
另一方面，所述基于音频的灯具控制方法中控制与灯具相互独立，也就是说，所述灯具控制方法可以应用于不同的需要音乐的控制的灯具，而不限于指定的或者相对应的灯具，从而使得应用范围更加广泛，举例地，可以应用于KTV或普通家庭中。
在所述步骤(A)中无线的方式采集各种音频设备的音频信号，特别是音乐信号。在一实施例中，采集通过匹配后的目标音乐，从而排除非控制音频信号的采集。因此，所述步骤(A)包括步骤：匹配音频信号。
在所述步骤(C)中，中以无线传输的方式传递控制信息，使得控制和灯具之间相互独立。特别地，在所述步骤(C)中以手机控制灯光。
所述基于音频的灯具控制***100执行上述方法的具体的执行过程可以是：所述音频采集单元110采集外部音响设备的音频信息，特别地，通过所述匹配模块111匹配音频信息，从而使得所述音频采集单元110采集目标音频信息。所述处理单元120处理获取的音频信息，将音频信号转化为灯光控制信号，特别地，将音频信号转换为根据音乐节奏变化变色及明暗程度的灯光控制信号。所述发送单元130发送控制信息至灯具端，特别地，以无线传输的方式传递控制信号。所述控制单元140接收控制信息，并将其转变为适宜控制灯具的信号。特别地，所述控制单元140接收其他设备的无线控制信号，从而以多种方式控制灯具的工作过程。
如图7至图11所示，是根据本发明的第二优选实施例的LED灯具控制装置。根据本发明实施例，提供了一种LED灯具控制装置，其包括：音频信号采集单元，配置为接收音频信号；处理单元，配置为根据所接收的音频信号产生用于控制LED灯具的灯光显示的控制信号；发送单元，配置为将所产生的控制信号发送到位于远程的LED灯具。
上述LED灯具控制装置可以与音响***和LED灯具本身完全独立地设置，因此可以不受限于指定的音响***或者LED灯具。具体地说，由于根据本发明的LED灯具控制装置与音响***完全独立，可以不受限于音响***，且因此可以具 有更广泛的应用场景，适配于各种音响***，降低现有音响***改造的成本，且不影响现有音响***的性能。另外，由于根据本发明的LED灯具控制装置与LED灯具本身完全独立，可以不增大LED灯具本身的体积，且可以极大地扩展可控制LED灯具中LED灯的数目。
图7是根据本发明第二个实施例的LED灯具控制装置的示意性框图。如图7所示，根据本发明实施例的LED灯具控制装置100A包括：音频信号采集单元110A，配置为接收音频信号；处理单元120A，配置为根据音频信号采集单元110A接收的音频信号产生用于控制LED灯具的灯光显示的控制信号；和，发送单元130A，配置为将处理单元120A所产生的控制信号发送到位于远程的LED灯具，以控制LED灯具变换灯光显示。
这里，根据本发明实施例的LED灯具控制装置所产生的控制信号可以控制LED灯具变换每个LED灯显示的颜色、亮度、频率等，从而使得LED灯具的灯光显示与音频相配合。这里，本发明实施例并不意在限制LED灯具的控制信号所控制的具体对象。
在上述LED灯具控制装置中，该音频信号采集单元包括：音频采集模块，配置为采集来自外部环境的音频；和/或音频输入模块，配置为通过有线或无线方式接收输入的音频。
因为本发明实施例的LED灯具控制装置与音响***完全独立地设置，所以在本发明实施例的LED灯具控制装置中，设置能够独立于音响***采集音频的部件。例如，根据本发明实施例的LED灯具控制装置可以通过麦克风等直接采集外部环境的音频，这可以使得该LED灯具控制装置不需要以任何形式与音响***连接。例如，可以将根据本发明实施例的LED灯具控制装置直接置于正在播放音乐的环境中，例如KTV，或者家庭中正在播放音乐的房间等，而不需要预先进行任何设置。当然，如果希望在一定程度上保证所采集的音频的精确性，也可以采用通过有线或者无线方式与音响***连接，从而接收音频输入的音频输入模块。这样，可以避免直接采样环境中的音频所造成的音频失真的问题。当然，本领域技术人员可以理解，因为LED灯具的显示灯光变换仅是对相对应的音频的模拟，所以对所采集的音频精确度的要求相对不那么高。
在上述LED灯具控制装置中，该发送单元为Zigbee无线发送模块。
实际上，根据本发明实施例的LED灯具控制装置可以以任何无线方式将用于控制LED灯具的灯光显示的控制信号发送给LED灯具。例如，无线发送模块可以采用的无线通信方式包括，但是不限于卫星通信、蜂窝通信、蓝牙、蓝牙低能量(BLE)、无线高清晰度多媒体接口(HDMI)、近场通信(NFC)、红外数据关联标准(IrDA)、无线高保真(WiFi)和用于微波访问的全世界互操作性(WiMAX)等。
在上述无线通信方式中，ZigBee是一种低速短距离传输的无线网络协议，其是基于IEEE802.15.4标准的低功耗个域网协议。ZigBee的主要特点是低功耗、低成本、低数据速率、支持大量节点、支持多种网络拓扑、低复杂度、自组织，且主要适合用于自动控制和远程控制领域，可以嵌入各种设备中。简而言之，ZigBee是一种低成本、低功耗的无线组网通信技术，由于其网络可以便捷的为用户提供无线数据传输功能，因此在物联网领域具有非常强的可应用性。
在根据本发明实施例的LED灯具控制装置中，由于LED灯具控制装置与LED灯具完全独立，且希望能够通过单一的LED灯具控制装置来控制大量的LED灯具，从而使得大量LED灯具根据LED灯具控制装置的控制来协同地变换灯光显示，根据本发明实施例的LED灯具控制装置优选地采用Zigbee无线通信方式。
具体地说，由于根据本发明实施例的LED灯具控制装置所发送的控制信号用于控制LED灯具以变换灯光显示，该信号并不需要包含大量的数据内容，因此，虽然Zigbee无线通信方式具有低数据速率的特点，但是并不会影响根据本发明实施例的LED灯具控制装置对LED灯具的控制性能，且可以发挥Zigbee无线通信方式的低成本和低功耗的特点。
此外，由于根据本发明实施例的LED灯具控制装置期望通过单一的LED灯具控制装置来控制大量的LED灯具，而该大量的LED灯具的分布可能是相对杂乱无章的，因此，Zigbee无线通信方式所具有的支持大量节点、支持多种网络拓扑、低复杂度、自组织的特点可以更好地支持根据本发明实施例的LED灯具控制装置以及大量受控LED灯具的拓扑结构。因此，即使各个受控LED灯具的位置不同，也可以保证各个受控LED灯具的显示灯光的变换的同步，从而改进LED灯具的灯光显示的性能。
所以，尽管如上所述，各种各样的无线通信方式都可用于根据本发明实施例 的LED灯具控制装置，但是根据本发明实施例的LED灯具控制装置优选地采用Zigbee无线通信方式，且配合本发明的技术方案，采用Zigbee无线通信方式可以获得如上所述的意料之外的效果。
在上述LED灯具控制装置中，进一步包括：电源单元，用于为该音频信号采集单元、处理单元和发送单元供电。
在根据本发明实施例的LED灯具控制装置中，电源单元可以根据音频信号采集单元、处理单元和发送单元的具体需要，给上述单元供电。例如，电源单元可以包括交流-直流(AC-DC)转换器，并且可以包括变压器以转换输入电压为适于各个单元的电压。例如，电源单元可以将5V的AC输入电压转换为3.3V的DC电压并输出到作为Zigbee无线发送模块的发送单元。
在上述LED灯具控制装置中，进一步包括：无线接收单元，配置为接收从外部发送的控制命令；其中，该处理单元进一步配置为根据所接收的音频信号和控制命令产生用于控制LED灯具变换灯光显示的控制信号。
在上述LED灯具控制装置中，进一步包括：无线接收单元，配置为接收从外部发送的控制命令；其中，该发送单元配置为将所产生的控制信号和所接收的控制命令发送到位于远程的LED灯具。
在根据本发明实施例的LED灯具控制装置中，除了根据音频信号采集单元所接收的音频来产生控制LED灯具的灯光显示以外，还可以通过无线接收模块进一步接收其它控制命令，以便进一步辅助控制LED灯具的灯光显示。例如，该控制命令可以来自于其它用户，当用户希望自主调节LED灯具的灯光显示时，便可以通过发送控制命令来实现其目的。
具体地说，根据用户的控制命令的具体类型，无线接收单元所接收的控制命令可以由发送单元直接发送给LED灯具，以控制LED的灯光显示。例如，当用户希望调节LED灯具的灯光显示的颜色、亮度、频率等可以直接控制的参数时，这种控制命令可以直接发送到LED灯具。但是，在某些情况下，用户对于LED灯具的灯光显示变换的需求可能并不能直接反映为上述LED灯具的可以直接控制的参数的变化。例如，用户希望配合节奏强的音频加快LED灯具的颜色变换，或者用于根据音频的种类希望采用特定的灯光显示变换的形式。这时，需要根据本发明实施例的LED灯具控制装置中的处理单元结合用户的控制命令来处理所接收 的音频，从而产生符合用户需要的用于控制LED灯具变换灯光显示的控制信号，以增强根据本发明实施例的LED灯具控制装置的功能性。
同样，根据本发明实施例的LED灯具控制装置中的无线接收模块也可以采用各种无线通信方式来从用户接收控制命令。随着移动设备的普及，越来越多的移动设备可以通过接入WiFi来进行无线通信。因此，优选地，根据本发明实施例的LED灯具控制装置中的无线接收模块为一WiFi模块，从而适于接收用户通过手机等移动设备发送的控制命令。
例如，当用户希望调节LED灯具的灯光显示时，可以拿出手机，通过WiFi连接根据本发明实施例的LED灯具控制装置中的无线接收模块，并通过安装在手机上的应用软件通过WIFI把控制命令发送给该无线接收模块。之后，根据本发明实施例的LED灯具控制装置根据控制命令的具体内容将其直接发送给LED灯具或者经过处理之后发送给LED灯具。
如上所述，根据本发明实施例的LED灯具控制装置可以与音响***和LED灯具本身完全独立，因此，可以被制造为独立的设备。例如，根据本发明实施例的LED灯具控制装置可以被制造为一种便携式的灯光控制盒子，从而适用于各种应用场景。
比如，该灯光控制盒子可以适配为用于KTV场景：当用户在KTV中唱歌时，如果希望获得更大的娱乐性，用户可以使用这种灯光控制盒子来根据正在播放的歌曲来调节KTV包房中的灯光显示，从而显著地增强气氛。并且，用户可以通过手机来连接该灯光控制盒子，从而根据用户的喜好来进一步调节包房内的灯光显示，这显然将对于用户具有极大的吸引力。
而且，这种灯光控制盒子由于其便携性，并不需要在每个KTV包房中进行安装，对于KTV的管理者来说，仅需要准备一定数量的这种灯光控制盒子，并在顾客有需要的时候出租给顾客使用，或者作为其它种类的增值服务提供给顾客。这样，一方面获取用户满意度的提高，另一方面也可以节省KTV管理者的硬件采购成本。
在根据本发明实施例的LED灯具控制装置中，处理单元可以根据具体需要，采用适当的软件来产生控制LED灯具的灯光显示变换。并且，这种控制灯光显示变换的软件是可更新的。例如，用户可以通过从网络下载来更新软件，从而获得 更多灯光显示变换的形式。用户也可以针对不同的音频来自己设计灯光变换的形式，从而获得个性化的定制灯光显示。这些都能够显著增强根据本发明实施例的LED灯具控制装置的功能性，并改进LED灯具的显示性能。
下面，将结合图8来具体描述根据本发明实施例的LED灯具控制装置的第一实例。图8为根据本发明实施例的LED灯具控制装置的第一实例的示意性框图，如图8所示，根据本发明实施例的第一实例的LED灯具控制装置200包括电源单元201，电源转换单元202，麦克风203，处理单元204，Zigbee模块205和WiFi模块206。
电源单元201与外部电源连接，从而将例如220V的AC市电转换为5V的AC电压，并输出给电源转换单元202。电源转换单元202具体地可以为AC-DC转换器，以进一步将5V的AC电压转换为3.3V的DC电压，以提供给处理单元204，Zigbee模块205和WiFi模块206。处理单元204通过模拟-数字(AD)接口读取麦克风203采集到的音乐数据，并根据所采集的音乐数据产生用于控制LED灯具的灯光显示变换的控制信号。之后，处理单元204将控制信号通过Zigbee模块205，例如，经由Zigbee 2.4G无线信号发送给LED灯具，该LED灯具例如可以是RGB灯具，从而根据所接收音频的音量、频率等自动变换亮度、颜色等。另外，WiFi模块206接收来自于手机的控制命令，将接收到的命令解析后通过Uart接口发送给处理单元204。如之前所述，处理单元204可以将结合音频信号和控制命令产生用于控制LED灯具的灯光显示变换的控制信号，或者直接将控制信号和控制命令发送给Zigbee模块205，然后再例如通过Zigbee 2.4G无线信号发送给RGB灯具，以使得RGB灯具能够进一步体现亮度和颜色的手动设置。
图9为与图8所示的根据本发明第二个实施例的LED灯具控制装置的第一实例对应的LED灯具的示意性框图。如图9所示，LED灯具300包括电源单元301、调制控制器302、电源转换器303、Zigbee模块304、多个LED恒流芯片305以及LED灯306。
电源单元301接收外部的交流输入，并输出到调制控制器302。调制控制器302一方面输出恒压直流输出给多个LED恒流芯片305，另一方面输出一路恒压直流到电源转换器303。电源转换器303将5V的直流电压转换为3.3V的直流电 压，从而给Zigbee模块304供电。Zigbee模块304接收例如来自于LED灯具控制装置200的Zigbee模块305的Zigbee 2.4G无线信号，并通过PWM控制多个LED恒流芯片305。多个LED恒流芯片205在Zigbee模块的控制下，从而经调制的直流电流，从而实现LED灯306的颜色和亮度的变化。
下面，将结合图10来具体描述根据本发明第二个实施例的LED灯具控制装置的第二实例。在根据本发明实施例的LED灯具控制装置的第二实例中，为了进一步缩小LED灯具部分的体积，将控制LED灯具的灯光变换的信号进一步解析为直接控制LED灯具的亮度、颜色等的恒压直流信号，从而使得LED灯具可以直接根据LED灯具控制装置所产生的信号显示所需亮度、颜色等。
图10为根据本发明第二个实施例的LED灯具控制装置的第二实例的示意性框图，如图10所示，根据本发明实施例的第二实例的LED灯具控制装置400包括电源单元401，电源转换单元402，麦克风403，处理单元404，Zigbee模块405和WiFi模块406和调制控制单元407。
其中，根据本发明这个实施例的第二实例的LED灯具控制装置400中包括的电源单元401，电源转换单元402，麦克风403，处理单元404，Zigbee模块405和WiFi模块406分别与根据本发明实施例的第一实例的LED灯具控制装置200中包括的电源单元201，电源转换单元202，麦克风203，处理单元204，Zigbee模块205和WiFi模块206相同，在此不再赘述。
LED灯具控制装置400与LED灯具控制装置200的不同在于进一步包括调制控制单元407。调制控制单元407接收来自处理单元204的控制信号，并将该控制信号解析为适于直接控制LED灯具的LED灯的亮度、颜色等的显示的数字信号，再将该数字信号通过Zigbee模块205发送到LED灯具。
