Abstract
A lighting control method for use in a lighting control system is disclosed. The lighting control method includes acquiring an influence coefficient of each of lighting devices on at least one local device based on a measured amount of invisible beams and a measured amount of visible light, the influence coefficient representing an influence level of each of the lighting devices on the local device; and acquiring a dimmer level of each of visible light sources based on a corresponding one of the influence coefficients to control the amount of the visible light measured at a position of the local device such that the measured amount of the visible light reaches or approaches a target lighting amount of the local device.
