PROBLEM TO BE SOLVED: To provide a lighting control system which controls lighting of overlapping portions of lighting regions desirably and capable of realizing the space saving and cost saving. SOLUTION: A lighting control system 1 comprises lighting devices 2 placed in respective lighting regions; a human detection sensor master unit 3 having a human detection sensor 14 for detecting whether a human body is present or not in each lighting region; a human detection sensor slave unit 4 having a human detection sensor 22 for detecting whether a human body is present or not in the overlapping portion 6 of lighting regions A, B, and being composed so as to change an input operation voltage when the own human detection sensor 22 detects the presence of a human body; and a lighting control device 5 being composed so as to control the respective lighting devices 2 in the two lighting regions A, B to be in a lighting state when a change in the operation voltage is detected.
