Abstract
The present invention provides an LED lighting device and an LED lighting network system. The LED lighting device includes an LED lighting unit, an LED driving circuit, a controller, and a Wi-Fi module configured to send and receive Wi-Fi signals. The LED driving circuit connects to the LED lighting unit. The controller connects to the Wi-Fi module and the driving circuit. The LED lighting network system includes two or more of the above LED lighting devices. Each LED lighting device works as a network node, which transmits received Wi-Fi data to other LED lighting devices within its coverage range. The LED lighting devices may form a mesh network. Each LED lighting device may act as a gateway, a network accessing point, or a repeater. The LED lighting network can receive and transmit Wi-Fi signals. In a mesh network, Wi-Fi signals can be transmitted from one layer of LED lighting devices to the next layer. Embodiments consistent with the present disclosure can overcome lighting network problems caused by obstacles in the Wi-Fi transmission range or the limitation of the Wi-Fi signal transmission range.
