  • System and method for wirelessly controlling LED lighting
    Patent number: 9532438
    Abstract: A system for wirelessly controlling LED lighting includes: a plurality of LED lamps, each lamp being equipped with a wireless communication module; and a smart device being in communication with the wireless communication module and configured to be controlled by a user. The smart device is configured to generate a unique lamp ID for each LED lamp, and embed the unique lamp ID into a signal for controlling each LED lamp through the wireless communication module so that the unique lamp ID is detectable in a form of visible light. The signal for controlling each LED lamp is a PWM signal, while data rate of the lamp ID is higher than that of the PWM signal. A method for wirelessly controlling LED lighting is also provided.
