参照图5a、图7、图9、图21，所述电路板100包括MCU主控模块101、和DMX控制模块104，并且，所述电路板100被安装在所述WIFI无线DMX灯具内。可以理解的是，参照图1至4中的现有技术的电路板，例如，图1中的DMX灯具的电路板包括主控单元、DMX控制单元、供电单元等。随着技术的进步，主控单元选用功能强大的MCU芯片，例如M0518主控芯片，参见文献 https://wenku.baidu.com/view/51975a4108a1284ac85043c3.html。

WIFI模块制造商:乐鑫信息科技上海股份有限公司；
WIFI模块型号：ESP8266贴片式Wi-Fi模组；
WFI模块参数：ESP-WROOM-02模组是基于ESP8266EX芯片设计开发的物联网无线模组。它集成了TCP/IP网络协议栈，32位低功耗MCU，10比特精度ADC，并带有HSPI、UART、PWM、I2C和I2S等接口；

如图8、图9所示，所述WIFI处理电路1021包括WIFI芯片U10，所述MCU主控模块101包括主控芯片U2；电阻器RC12的一端与所述WIFI芯片U10的管脚22连接，另一端与所述主控芯片U2的管脚8电连接；电阻器RC13一端与所述WIFI芯片U10的管脚21连接，另一端与所述主控芯片U2的管脚9电连接；并且，所述WIFI芯片U10与移动智能WIFI终端基于UDP传输层通讯协议进行无线通讯。可以理解的是，作为实例，所述WIFI芯片是上述商用的ESP8266贴片式Wi-Fi模组，其提供的逻辑处理功能和管脚功能完全能够满足数据的收发、处理、与DMX灯具的MCU主控模块101通讯、与WIFI客户端例如智能手机通讯的要求。所述WIFI芯片U10的管脚22用于接收来自所述主控芯片U2的管脚8传输的数据，所述WIFI芯片U10的管脚21用于发送数据至所述主控芯片U2的管脚9，从而实现所述主控芯片U2与所述WIFI芯片U10的双向数据通讯。所述WIFI芯片U10与智能手机之间的无线通讯在UDP传输协议层是现有技术，也就是，无需更改移动智能WIFI终端或者智能手机的硬件例如手机的WIFI模块，使用本申请人编写的DMX灯具手机控制终端APP,所述DMX灯具手机控制终端APP与所述WIFI芯片U10通过常规格式的 UDP数据包进行通讯，无需新的数据传输协议。当然，所述主控芯片U2与所述WIFI芯片U10的双向数据通讯是由本申请人编写程序代码进行特定数据处理，其详细细节不是本发明的保护范围，不在这里详细描述。本发明的要点之一在于将先进的WIFI芯片直接集成到DMX灯具中，实现了用常规的UDP传输层通讯协议来控制DMX灯具，这是现有技术没有实现的。本发明的要点之二在于所述主控芯片U2与所述WIFI芯片U10之间的物理电连接方式不同于现有技术，实现了UDP数据包到DMX数据包的高效解码。
如图6、图9所示，所述LED-PWM调光模块103包括排插JP6，所述主控芯片U2的管脚24、管脚23、管脚22、管脚21分别与所述排插JP6的连接线PWM1、连接线PWM2、连接线PWM3、连接线PWM4连接。可以理解的是，所述LED-PWM调光模块103的所述排插JP6将所述主控芯片U2与所述LED灯板电连接在一起，将解码的DMX控制指令发送至所述LED灯板，在不用更改现有的DMX灯具的硬件的情形下，直接使用DMX512通讯协议规定DMX控制指令控制所述LED灯珠产生灯光变化。当然，所述主控芯片U2解码后的DMX数据格式和数据信息是现有技术，这里不再详细描述。因此，本发明的要点之三在于，基于所述排插JP6将所述主控芯片U2与所述LED灯板电连接，在DMX灯具的硬件除电路板外没有其它改动的情况下，通过常规的WIFI通讯实现对专业的DMX灯具的控制。
如图6、图8、图9所示，所述WIFI无线DMX灯具还能够按如下方式产生所述设定的灯光变化效果：
所述WIFI无线模块102将接收到的第一灯光控制信息通过所述WIFI芯片U10的管脚21传输给所述MCU主控模块101的主控芯片U2；
所述主控芯片U2处理所述第一灯光控制信息，并生成第二灯光控制信息；

所述LED-PWM调光模块103按所述第二灯光控制信息控制所述LED 灯板200，产生所述设定的灯光变化效果。
可以理解的是，所述第一灯光控制信息是所述移动智能WIFI终端发送的UDP数据包，其中，UDP全称为用户数据信息传输协议，UDP传输协议是一种不可靠的、面向无连接、可以实现多对一、一对多和一对一连接的通信协议。UDP在传输数据前既不需要建立通道，在数据传输完毕后也不需要将通道关闭。只要客户端给服务端发送一个请求，服务端就会一次性地把所有数据发送完毕。UDP在传输数据时不会对数据的完整性进行验证，在数据丢失或数据出错时也不会要求重新传输，因此也节省了很多用于验证数据包的时间，所以以UDP建立的连接的延迟会比以TCP建立的连接的延迟更低。由于UDP数据格式可以根据使用需要进行自定义，因此，所述第一灯光控制信息可以是用户定义的数据格式，也可以使用标准协议定义的数据格式，例如Art-Net通讯协议，详细信息参见 www.Art-Net.org.uk。
上述WIFI无线DMX灯具基本达到了使用常规的WIFI无线通讯方式控制DMX灯具的技术效果，同时又无需对DMX灯具的电路板之外的硬件进行改动。
作为变型，为简化WIFI无线DMX灯具，可以不包括DMX信号输入端口和DMX信号输出端口，电路板也可以省略DMX控制模块104，直接通过WIFI无线控制每个灯具。

如图6、图8、图9所示，所述WIFI无线DMX灯具还能够按如下方式产生设定的灯光变化效果：

具体的UDP数据包的数据结构：其包括ART-NET地址+IP地址+DMX数据，其中，因为WIFI热点就一个，所以WIFI热点的IP地址是固定的，手机的IP地址是WIFI热点分配的。
图25为本发明创造的灯光控制系统的WIFI无线模块解码DMX控制指令数据的流程图，其使用第1种灯具连接方式。
具体步骤如下：
步骤S101：打开手机app软件，并连接到wifi模块的热点；
步骤S102：wifi模块的Artnet协议搜索灯具；
步骤S103：建立灯具ip地址和artnet地址的对应关系，每个artnet地址代表一路dmx总线；
步骤S104：建立灯具映射表，dmx地址和灯具的对应关系；
步骤S105：选择一个编程文件，选择artnet地址，并选择需要控制的灯具；

2-每台灯具均装有WIFI模块的控制方式，手机可与任意灯具直接建立连接。其又分为两种子连接方式：
2A-没有路由器的情况:手机根据需要连接特定的单台灯具,建立WIFI连接,然后进行点对点的单台的任何控制。其数量为无限，每一台灯具相当于1个WIFI热点，使用手机连接上所需要的WIFI热点即可。
DUP数据包的数据结构：其包括ART-NET地址+IP地址+DMX数据，因为WIFI热点就一个，所以WIFI热点的IP地址是固定的，手机的IP地址是WIFI热点分配的。

具体步骤如下：
步骤S201：打开手机app软件，并连接到公共路由器；
步骤S202：所有的灯具的wifi模块连接到公共路由器；
步骤S203：Artnet协议搜索灯具的wifi模块；
步骤S204：建立灯具ip地址和artnet地址的对应关系，每个artnet地址代表一路dmx总线；
步骤S205：建立灯具映射表，dmx地址和灯具的对应关系；
步骤S206：选择一个编程文件，选择artnet地址，并选择需要控制的灯具；
步骤S207：触发播放；

步骤S2010：不同的数据包，分别发往不同的ip地址；
步骤S2011：Wifi模块接收到网络数据包；
步骤S2012：Wifi模块解释dmx数据，并把它按照dmx时序发送出去；
步骤S2013：继续播发数据？如果是，回到步骤S107，如果否，结束播发数据包。
控制方式如下：
①特定单台控制：
在APP里进行搜索，因为手机、多台灯具、路由器已经形成了一个局域网，每台灯具都含有WIFI模块，因此每台灯具都从路由器分配1个的IP地址。在手机里，所有灯具的信息都可以查找出来，需要控制哪一台，选择对应的灯具，先让灯具高亮进行确认后再进行控制即可。
DUP数据包的数据结构：其包括ART-NET地址+IP地址+DMX数据，其中，特定的灯具IP地址，由路由器分配而来。
②多台统一动作控制：
在APP里进行搜索，因为手机、多台灯具、路由器已经形成了一个局域网，每台灯具都含有WIFI模块，因此每台灯具都从路由器分配1个的IP地址，然后根据需要将多台灯具分到一个组内，然后发送控制指令给这个组，组内的灯具就会统一按照指令进行对应的表演。
DUP数据包的数据结构：其同时发送多个数据包，每个数据包控制1台灯具，每个数据包包括ART-NET地址+IP地址+DMX数据，其中，特定的灯具IP地址，由路由器分配而来；DMX数据包括DMX通道值，DMX通道值对应灯具的地址码。
此时，因为是统一动作控制，DXM数据包内的通道值是一样的。
③多台不同的动作控制：
DUP数据包的数据结构：其同时发送多个数据包，每个数据包控制1 台灯具，每个数据包包括ART-NET地址+IP地址+DMX数据，其中，特定的灯具IP地址，由路由器分配而来；DMX数据包括DMX通道值，DMX通道值对应灯具的地址码。
此时，因为是不同的灯具进行不同的动作控制，DXM数据包内的通道值是不一样的。
以上详细描述了本发明创造的优选的或具体的实施例。应当理解，本领域的技术人员无需创造性劳动就可以根据本发明创造的设计构思做出诸多修改和变化。因此，凡本技术领域中技术人员依本发明创造的设计构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在本发明创造的范围之内和/或由权利要求书所确定的保护范围内。
