Claim Text:
1. A lighting fixture comprising: an LED; a human detecting sensor configured to detect a person; and a controller configured to set a light modulation level of the LED in accordance with a detection result of the human detecting sensor; the controller being configured to set the light modulation level to a first light modulation level in a period from a beginning of a night time slot until when a predetermined first time period elapses, regardless of the detection result of the human detecting sensor, the controller being configured to set the light modulation level to a second light modulation level that is lower than the first light modulation level when the first time period elapses, the controller being configured to set, when the human detecting sensor detects a person in a state where the light modulation level is set to the second light modulation level, the light modulation level to the first light modulation level for a predetermined time period, and the controller being configured to set the light modulation level to the second light modulation level regardless of the detection result of the human detecting sensor, when a predetermined second time period elapses after the first time period has elapsed.
