Abstract

The utility model discloses a light emitting diode (LED) light and a LED lighting network system. The LED light comprises an LED luminescence assembly, an LED driving circuit, a controller and a wireless fidelity (Wi-Fi) module which receives and emits Wi-Fi signals. The LED driving circuit is connected with the LED luminescence assembly. The LED lighting network system is composed of at least two LED light pitch points as mentioned above. Each pitch point transmits the received Wi-Fi signals to other pitch points which are within a covering range of the Wi-Fi signals, so that a net-shaped structural wireless network based on Wi-Fi is formed. The LED light can simultaneously be a radio network gateway, an access point and a repeater of the Wi-Fi wireless network. As long as one LED light receives the Wi-Fi signals, the signals can be transmitted layer upon layer, the covering range of the LED wireless network can be continuously extended and expanded, and limitation of propagation distance and penetrability of the Wi-Fi signals can be broken through.
