  • Publication number: 20140300277
    Abstract: Plural luminaires are installed in a lighting space surrounded by a wall part. A sensor equipment detects existence or nonexistence of a person in the lighting space. If existence of a person in the lighting space is detected, the sensor equipment detects a direction of the person. The sensor equipment detects a distance between the wall part positioned in front of the direction of the person and the person. A lighting control unit selectively switches between a first control for performing lighting control of the luminaires to illuminate the wall part positioned in front of the direction of the person if the detected distance is a specified distance or less, and a second control for performing lighting control of the luminaires to reduce brightness at a place as the place becomes farther from a position of the person if the detected distance is larger than the specified distance.
