Abstract

An intelligent lighting control system, a control method, and an intelligent lighting system, the intelligent lighting control system comprising: a main controller, a PWM data buffer controller, and a time base generator, wherein: the main controller is adapted to receive user input the dimming instruction, generate the corresponding target pulse width adjustment parameter according to the dimming instruction, send the target pulse width adjustment parameter to the PWM data buffer controller, and send the PWM wave to the PWM data buffer controller Generate instructions; the PWM data buffer controller is adapted to store the target pulse width adjustment parameters, and when receiving the PWM wave generation instructions, control the time base generator to generate and adjust the target pulse width parameters Corresponding PWM wave; the time base generator is adapted to generate a PWM wave corresponding to the target pulse width adjustment parameter, and input the generated PWM wave to the LED driving circuit. The above-mentioned solution can reduce the demand on the computing performance of the MCU when the LED lighting equipment performs dimming.
