Lighting system and control method thereof

摘要

A lighting system according to embodiments includes a first light source (22R, 22G, and 22B), a second light source (22R, 22G, and 22B), a first lighting circuit (104, 105, and 106), a second lighting circuit (104, 105, and 106), a signal input unit (25), and a control circuit (112). The first light source (22R, 22G, and 22B) has a predetermined color temperature. The second light source (22R, 22G, and 22B) has a color temperature which is different from that of the first light source (22R, 22G, and 22B). The first lighting circuit (104, 105, and 106) lights the first light source (22R, 22G, and 22B). The second lighting circuit (104, 105, and 106) lights the second light source (22R, 22G, and 22B). The signal input unit (25) receives an external signal. The control circuit (112) includes a first light source lighting control cycle and a second light source lighting control cycle. The first light source lighting control cycle performs a predetermined lighting control of the first light source (22R, 22G, and 22B). The second light source lighting control cycle performs a predetermined lighting control of the second light source (22R, 22G, and 22B). The control circuit controls the first and second lighting circuits (104, 105, and 106) so as to start the lighting control based on the first and second light source lighting control cycles by the first signal which is input to the signal input unit (25), and controls the first and second lighting circuits (104, 105, and 106) so as to stop the lighting control based on the first and second light source lighting control cycles by the second signal which is input to the signal input unit (25).
