Abstract

PURPOSE:To automatically set an adequate lighting space by providing a detecting unit detecting the number and position of human beings or the like requiring lighting in a detection area and an arithmetic processing unit. CONSTITUTION:A detecting unit 11 detecting the number and position of human beings or the like requiring lighting in a detection area, a pattern setting unit 12 setting in advance the lighting pattern of a lighting device 13 in response to the number and position of the objects, and an arithmetic processing unit 15 collating the detection signal from the detecting unit 11 and the lighting pattern and selecting the adequate lighting pattern and outputting the selected signal are provided. The proper lighting environment is thereby set automatically based on the number and position of human beings or the like requiring lighting in a detection area.
