To provide a luminous system enabling display of infinite kinds of graphical luminescent patterns by independent control of each luminous element.

This system 100 has linear electric decorative illuminations 130(1301-130n), and each of the linear illuminations has plural independently controllable light modules 140(1401,1-140n,m) emitting light in response to operating signals unique to respective light modules. This system 100 includes a control device 110 integrated with the linear illuminations 130, for generating the operating signals to transmit them to the light modules 140 in order to independently control the lights of the light modules 140. Each light module includes a multicolor luminous device emitting lights of various colors, and the control device 110 can select the color of the light to be emitted among the plural light modules 140. This system 100 includes plural address modules 120(1201-120n) each of which is associated and connected with the one linear illumination, and connected with the control device 110. The control device 110 can send the operating signals to the plural light modules of the particular linear illumination by sending the address.
