<p>PROBLEM TO BE SOLVED: To provide a lighting system capable of conducting optimum control of a luminaire and reducing cost without requiring the main device for centralized control and an address. SOLUTION: In a luminaire 1, when a human sensitive sensor 11 detects a human body, a control part 13 lights an illumination load 12, and sends detected information detected through a communication part 17 through a signal line 18. At the same time, the control part 13 recognizes that the luminaire 1 to which it belongs is a leader luminaire. Other luminaire 1 in the periphery of the luminaire 1 takes in detected information sent through the signal line 18, and at the same time, recognizes that itself is a follower luminaire and the luminaire 1 from which detected information is sent is a leader luminaire.</p> |
