PROBLEM TO BE SOLVED: To provide a lighting control system which can easily eliminate a lighting failure of an illumination device even if there exists an illumination device having erroneous lighting because simultaneous transmissive communication is not properly performed, when lighting control of a plurality of lighting devices connected in parallel with a controller is performed with communication from the controller. SOLUTION: The controller makes simultaneous transmissive communication of a group control command for turning on illumination to respective illumination devices 1 to n. The controller performs communication of result confirmation to respective illumination devices 1 to n in sequence. Each illumination device normally receiving the simultaneous transmissive communication sends a reply of OK as a result response, and when result responses from a part of the illumination devices 2 are different from received contents in case of normal receiving and the illumination device is not turned on as an error (NG), the controller performs lighting control by making individual communication to respective illumination devices 2 in response to the result response. When the illumination device 2 receives the individual communication and sends a reply of OK as a result response similarly to a case of normal reception, lighting failure of the illumination device 2 is eliminated.
