The invention discloses a wireless networking control method and system of an induction LED lamp. The method comprises the steps of networking a control end, a first LED lamp and a second LED lamp; sending a control parameter to the first LED lamp by the control end; receiving the control parameter by the first LED lamp; automatically a current state by the first LED lamp according to the controlparameter; and generating a pre-fabrication code to store the current state by the first LED lamp, and sending broadcasting and transmitting the current state parameter to the second LED lamp. The device comprises the control end, the first LED lamp and the second LED lamp. By wirelessly networking of the control end and the induction LED lamp, and the parameter of an induction LED is adjusted bya wireless mode; moreover, the LED lamp can pre-fabricate code to store the current state, the current state parameter is broadcasted and copied to other LED lamps, so that one arbitrary LED lamp canbe used as a main induction lamp and also can be used as a slave induction lamp, the randomness of application installation is greatly improved, and the user experience is enhanced.
