The smart home appliance 3 can include a wireless receiver module 30 networked with the smart terminal 2. In one embodiment, the smart home appliance 3 can be wirelessly connected with the smart terminal 2.


In an exemplary embodiment, voice commands can be directly sent to the LED lighting device 1, for example, by a user. The microphone module 13 in the LED lighting device 1 can capture signal data (e.g., audio signal) from the voice commands, which can then be processed by the controller unit 11 to provide control data.


The control data can be sent to the smart terminal 2 via the wireless communication module 12 in the LED lighting device 1. Because the smart terminal 2 has been built-in with the voice recognition module 20, the user's voice commands (signal data) can be recognized and further processed by the voice recognition module 20. The processed control signal can then be sent, via the wireless transceiver module 21 of the smart terminal 2, to one or more smart home appliances 3 (e.g., white and black appliances) that are networked with the smart terminal 2.


The operation of the one or more smart home appliances 3 can thus be controlled according to the processed control data. Such one or more smart home appliances 3 can include substantially all smart home appliances that are related or connected to the smart terminal 12, or include those selected from all of the smart home appliances according to the processed control data. In this manner, the disclosed LED lighting device can be used in a control system to control operations of smart home appliances.


The smart terminal in the LED control system can be a fixed gateway controller. Alternatively, a mobile phone, a computer and/or other suitable devices can be used to replace the gateway controller to check status and to remotely control the smart home appliance(s).


The at least one LED lighting device, the smart terminal, and the at least one smart home appliance can communicate with one another, e.g., via internet or any suitable network. The smart terminal can be configured to read status of the smart home appliance(s) and to locally and/or remotely control operational status of the smart home appliance(s).

Meanwhile, operations of related smart home appliance(s) can be controlled by the controller unit of the LED lighting device and the smart terminal.


In some embodiments, multiple LED lighting devices may be included in the LED control lighting system and used to accommodate various user needs. For example, different users may individually send a voice command to different LED lighting devices to control lighting of each LED light device and to control operations of the same or different smart home appliance(s), simultaneously or sequentially. In some cases, a same LED lighting device may be used to control the same or different smart home appliance(s) at different times. In other cases, different LED lighting devices may be used to control the same smart home appliance(s) at different times.


In this manner, the disclosed LED lighting device and LED control system can wirelessly control lighting (e.g., dimming) of the LED lighting device(s) and can also control operations of smart home appliance(s). The disclosed device and system can also be easily installed and assembled without changing existing wirings/cablings. The disclosed LED lighting device can be used to replace traditional lamps and traditional LED lights.


In various embodiments, a server such as a cloud server can be used to replace the terminal device. For example, while the terminal device can provide local voice recognition, the cloud server can provide cloud voice recognition. An exemplary LED control system may thus include at least one LED lighting device, a cloud server, and/or at least one smart home appliance. In one embodiment, the cloud server can at least include a voice recognition module and/or one or more processors.


In an exemplary embodiment, voice commands can be directly sent to the LED lighting device by a user. The microphone module in the LED lighting device can capture signal data (e.g., audio signal) from the voice commands, which can then be processed by the controller unit to provide control data. The control data can be sent to the cloud server via the wireless communication module in the LED lighting device. User's voice commands (signal data) can be recognized and further processed by the voice recognition module and the processor in the cloud server. The processed control signal can then be sent from the cloud server to one or more smart home appliances that can communicate with the cloud server. In this manner, the disclosed LED lighting device can be used in a control system to control operations of smart home appliances via the cloud server.
