<p>PROBLEM TO BE SOLVED: To provide an illumination system in which there is no collision of infrared rays and wiring work of signal lines to each illumination apparatus is not required. SOLUTION: The illumination system comprises a control means A which is installed in a plurality of illumination apparatuses A 11, 12 having a human body detection sensor 7 and, when there is an output of the human body detection sensor 7, the control means A generates a control signal setting as a transmitting number the illumination degree information, a transmitting number selection information and its transmitting number and controls illumination and, by calculating the transmission time band from its own transmitting number, outputs to the infrared transmitter 6, and a control means B which is installed in the illumination apparatuses B 12-15 having no human body detection sensor 7 and, when received a control signal from the other illumination apparatuses A 11, 16 or the illumination apparatuses B 12-15, controls illumination by the illumination degree information, and changes the transmitting number information into its own transmitting number, and outputs to the infrared transmitter 6 at the calculated transmission time band. The control means A, when received the control signal, makes illumination control by the illumination degree information of the control signal, and changes the transmitting number into its own transmitting number and outputs to the infrared transmitter 6 at the calculated transmission time band.</p> |
