Abstract

PROBLEM TO BE SOLVED: To provide a lighting system capable of coping with the change of signals so as not to give an unpleasant feeling to users by detecting the presence of a signal with an interface which inputs the signal from a dedicated controller and a light control board and converts it into a low speed digital signal, and controlling a light source. SOLUTION: A low speed dedicated signal from a dedicated controller 1 and a high speed DMX signal from a light control board 2 are inputted into an interface 3, converted into a low speed digital signal, and outputted to a lighting system 4. In each luminaire 4, based on the low speed digital signal, each light source 6 is controlled through a control block 5. In the lighting system, the presence of the signal,inputted in the interface 3 is detected, and when either one of a DMX signal and the dedicated signal is not inputted, the control block 5 is controlled according to the inputted signal. When input of the inputted signal is stopped, the interface 3 controls the light source 6 so as to light on or out.
