  • System and method for controlling LED lighting by distributed PWM
    Patent number: 10129940
    Abstract: The present invention relates to an illumination control method and system for LED lamps, where the system comprises: a receiver module (1) configured to obtain a number of illumination levels (N) indicative of the light resolution of a LED lamp (6) and a duty cycle (D) associated with a desired light intensity for a LED lamp (6), a control module (2) comprising a control unit (7) configured to: generate a periodic signal with a period (T) and a duty cycle from the number of illumination levels (N) and the duty cycle (D), generate an illumination control signal (SCi) from the periodic signal for controlling the power supply of at least one LED lamp (6), and a power supply module (3) configured to power at least one LED lamp (6) according to the illumination control signal (SCi).
