Patent ID: 8446110

Claim:
An illumination system, comprising: a plurality of illumination devices respectively allotted with specific identification codes; an imaging device for taking an image of an illumination space to be illuminated by the illumination devices; and a control device for controlling the illumination devices to illuminate the illumination space based on the image of the illumination space taken by the imaging device, wherein each of the illumination devices includes an light source, a lighting circuit unit for turning on or off the light source and a transmission control unit for performing data transmission between itself and the control device by using the corresponding identification code as its own address and for controlling the lighting circuit unit to turn on or off the light source according to a control command transmitted from the control device, wherein the control device includes a storage unit for storing correlations between the identification codes of the illumination devices and the illumination areas illuminated by the illumination devices, a transmission processing unit for transmitting a transmission signal containing the control command to the illumination devices by using the identification codes as destination addresses and a main control unit for selecting a control-target illumination area based on the image of the illumination space taken by the imaging device, reading out the identification code corresponding to the selected illumination area from the storage unit and causing the transmission processing unit to transmit a transmission signal containing a control command on the illumination device allotted with the read-out identification code by using the read-out identification code as a destination address, the main control unit being operable in an initial setting mode in which the correlations between the identification codes of the illumination devices and the illumination areas are set by causing the imaging device to take an image of the illumination space while turning on the illumination devices one after another and detecting the illumination area of each of the illumination devices from the image thus taken.
