Zusammenfassung:	An illuminating device may include optical sources, a diffusion plate having emission regions corresponding to the optical sources, and a control unit configured to control lighting-up/lighting-out and an emission intensity of the optical sources based upon a schedule when carrying out performance on an optical travel by the diffusion plate. The emission regions each may have a predetermined length and extend in a longitudinal direction of the diffusion plate. In the schedule, a light-up/light-out state of each optical source and an emission intensity of an optical source to be lit up are set based upon an average illuminance in an illuminance distribution of the diffusion plate by combining illuminances of lights emitted from the emission regions. For realizing a temporal change of the average illuminance set, the light-up/light-out state of each optical source and emission intensity of the optical source to be lit up in each time point are set.
