The invention provides an intelligent lighting control method and system, a program product and a storage medium, and relates to the technical field of lighting control. By periodically sending a clock calibration request and recording a plurality of time points, the network delay of each lighting controller can be accurately calculated. And when the network delay exceeds a threshold value, the system groups the controllers according to the physical distance, and selects the controller with the minimum delay as an intra-group clock source to realize intra-group accurate calibration. Meanwhile, the load of each controller can be balanced by calculating the load state index and dynamically adjusting the control range. The layered clock synchronization mechanism is combined with a load balancing strategy, so that the time sequence difference between the controllers is reduced, the response delay during cross-regional scene switching is reduced, and the problem of asynchronous illumination is solved.
