<p><P>PROBLEM TO BE SOLVED: To provide a light emission device, a light emission system, a light emission pattern changing method, a light emission method for a light emission system and an irradiation device, which can change setting of quite a new light emission control pattern in noncontact manner even after manufacturing a light emission device, without oppressing a space for light emission means and a solar cell. <P>SOLUTION: Since changing of a light emission control pattern is performed in a noncontact manner using an optical signal, a waterproof property can not be lost. In addition, a solar cell also serves as a light receiving section for the optical signal, so that a new sensor member is not required. Furthermore, a light emission control section of the light emission device prepares a light emission control pattern based on the optical signal, so that the light emission control pattern can be set in a relatively free manner. The light emission system optimizes light emission control patterns of individual light emission devices, thereby making it possible to display a light emission pattern, continuous images or the like which have a high decoration property as a whole light emission body. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
