Led lighting device, wireless network and control method thereof

A first light-emitting diode (LED) lighting device, comprising an LED lighting source;

• a first detecting module, a first processing module, a first wireless communication module for communicating with a wireless router in an LED lighting device-based wireless mesh network, and a second wireless communication module for communicating with at least one second lighting device in the LED lighting device-based wireless network, wherein:
• the first wireless communication module is connected to the first processing module;
• the second wireless communication module is connected to both the first wireless communication module and the first detecting module;
• after the second communication module receives a master-light-selecting broadcast message, the first detecting module receives a detection request sent by the second wireless communication module and detects a signal strength of the wireless router based on the detection request;
• when the first processing module determines a signal strength detected by the first detecting module has a maximum value among signal strengths detected by the plurality of LED lighting devices in the LED lighting device-based wireless network, the first wireless communication module forms a connection with the wireless router, and sends an LED network-forming request to the second wireless communication module;
• and
• the second wireless communication module sends a master-light-notifying broadcast message to the at least one second LED lighting devices, and forms a connection with the at least one second LED lighting devices, the master-light-notifying broadcast message including an identification of the first LED lighting device.

A second light-emitting diode (LED) lighting device, comprising:

• an LED lighting source, a second detecting module, a second processing module, and a third wireless communication module for enabling communication between a first LED lighting device and the second LED lighting device in an LED lighting device-based wireless mesh network, wherein:
• the LED lighting device-based wireless mesh network includes a wireless router, the first LED lighting device, and at least one second LED lighting device;
• the third wireless communication module is connected to the second detecting module and the second processing module;
• the second detecting module receives a detection request sent by the third wireless communication module after the third wireless communication module receives a master-light-selecting broadcast and detects a signal strength of the wireless router based on the detection request;
• when the second processing module determines a signal strength of the wireless router detected by the second detecting module does not have a maximum value among signal strengths detected by the plurality of LED lighting devices in the LED lighting device-based wireless mesh network, the second processing module sends a master-light-obtaining signal to the third wireless communication module;
• and
• the third wireless communication module receives the master-light-obtaining signal, receives a master-light-notifying broadcast message containing identification of the first LED lighting device sent by the first LED lighting device, and forms a connection with the first LED lighting device based on the identification of the first LED lighting device.
