PROBLEM TO BE SOLVED: To provide a lighting control system capable of surely performing lighting control while suppressing generation of noise.SOLUTION: A first switch instructs luminosity of a light-emitting element into a first state. A second switch instructs the luminosity of the light-emitting element into a different second state. A first control part generates a first control signal for generating a first command signal by removing a plurality of half cycles of an AC power source correspondingly to a zero cross point of the AC power source based on an output signal of the first switch and generates a second control signal for generating a second command signal by removing a plurality of half cycles of the AC power source correspondingly to the zero cross point of the AC power source based on an output signal of the second switch. A switching element outputs the first command signal based on the first control signal and outputs the second command signal based on the second control signal.SELECTED DRAWING: Figure 1 |
