<p>PROBLEM TO BE SOLVED: To adequately control illumination by organically combining the detecting performance of a circumference detecting means for detecting a circumferential state and a remote control function using a transmitter. SOLUTION: A luminaire A has a human body sensor part 1 for detecting a circumferential state, an illumination intensity sensor part 2, a receiving part 7 for receiving a wireless control signal from a transmitter B, and a receiving intensity measuring part 8 for measuring receiving intensity. When the receiving intensity from the transmitter B is low, a luminaire control part 10 identifies the place of the transmitter B based on the receiving intensity. Based on the identified result, the luminaire control part 10 controls the detecting sensibility of the human body sensor part 1 through a sensitivity control part 3. The detecting sensibility of the place where an operator of the transmitter B exists is raised, and a human body is surely detected. As a result, the detecting performance of the human body sensor part 1 and the remote control function by the transmitter B are organically combined, and illumination is adequately controlled.</p> |
