1. A lighting control system comprising:
- a plurality of luminaires set in a lighting space;
a presence detecting unit configured to detect presence of a person in the lighting space;
a luminance detecting unit configured to detect indirect luminance in a predetermined position in the lighting space; and
a control unit configured to subject the luminaires to lighting control such that the indirect luminance detected by the luminance detecting unit at a position where the presence detecting unit detects the presence of the person, does not fall below a predetermined value.

Abstract
According to one embodiment, a lighting control system includes a plurality of luminaire, a sensor device, a luminance sensor, and a lighting control unit. The luminaires are set in a lighting space. The sensor device detects presence of a person in the lighting space. The luminance sensor detects indirect luminance in a predetermined position in the lighting space by the luminaire. The lighting control unit subjects the luminaire to lighting control such that the indirect luminance detected by the luminance sensor does not fall below a predetermined value in a position where the sensor device detects presence of the person.
