<p>PROBLEM TO BE SOLVED: To provide a lighting system capable of easily recognizing surrounding position information and a surrounding luminaire condition and precisely controlling each control unit. SOLUTION: A luminaire 1 has a load control part 14 comprising an illumination intensity sensor 10, a human sensitive sensor 11, and a control part 13 which controls an illumination load 12 based on a detecting signal of the illumination intensity sensor 10 and a detecting signal of the human sensitive sensor 11. When an illumination load 12 of an adjacent luminaire 1 having the same constitution is lit based on the detection of a human body M by the human sensitive sensor 11, the lighting is detected by the variation of the detected illumination intensity of the illumination intensity sensor 10, the control part 14 recognizes that the adjacent luminaire 1 is lit by the detection, and lights the illumination load 12.</p> |
