Abstract
A lighting system according to embodiments includes a first light source, a second light source, a first lighting circuit, a second lighting circuit, a signal input unit, and a control circuit. The first light source has a predetermined color temperature. The second light source has a color temperature which is different from that of the first light source. The first lighting circuit lights the first light source. The second lighting circuit lights the second light source. The signal input unit receives an external signal. The control circuit includes a first light source lighting control cycle which performs a predetermined lighting control of the first light source, and a second light source lighting control cycle which performs a predetermined lighting control of the second light source, controls the first and second lighting circuits so as to start the lighting control.
