<p>PROBLEM TO BE SOLVED: To provide an illumination controller subjected to control of its illumination in response to presence/absence of a human body in detection area all the time. SOLUTION: A sub-apparatus B including a human body sensing part 1, a brightness sensing part 2, a sub-controller 3 and a transmitting part 4 for transmitting control commands by signals, and a main apparatus A including a receiving part 5 for receiving signals from the transmitting part 4 and a main control part 6 are provided, and plural lighting system C1 ... are connected to the main apparatus A. When no human body exists in a detection area, a luminaire C is turned off and the brightness detecting part 2 and the sub- controller 3 of the sub-apparatus B stop their functions because of cut power supply, etc. When the human body sensing part 1 senses existence of a person, power supply to the brightness sensing part 2 and the sub-controller 3 is started and the sub-controller 3 creates a control command corresponding to the level of brightness sensed by the sensing part 2 so as to have it transmitted from the transmitting part 4 by a wireless signal.</p> |
