Abstract:
A lighting apparatus (1) that comprises: a light-emission unit (30) that emits light; and a control unit (20) that controls output of light. In a prescribed lit state, the light-emission unit (30) emits light at first output. The control unit (20) has a first mode in which control is performed such that, at least once during a first period, output of light is reduced from a maximum output that is lower than the first output to a minimum output that is lower than the maximum output. The first period is at least 2 seconds but no more than 35 seconds. The minimum output is no more than 5% of the first output.
