LIGHTING SYSTEM AND REST ROOM

To provide a lighting system capable of suppressing disturbance of sleep of a user.SOLUTION: A lighting system 3 comprises at least: a lighting fixture; a control unit 92 for changing light output of the lighting fixture; and a control starting instruction unit 50. In the lighting system 3, when a starting instruction from the control starting instruction unit 50 is acquired, the control uni 92 executes gradual increase and gradual decrease of the light output a plurality of times within a fixed time. The fixed time includes an F amplitude phase which is set to a first half and an L amplitude phase which is set to a latter half of the fixed time. When a maximal value after the first gradual increase in the F amplitude phase is defined as Fmax, a minimal value after the first gradual decrease is defined as Fmin, a maximal value after the final gradual increase in the L amplitude phase is defined as Lmax and a minimal value after the final gradual decrease is defined as Lmin, relations of 1
