ILLUMINATING DEVICE

There is provided an illuminating device in which a plurality of emission regions W(1) to W(n) corresponding on a one-to-one basis to a plurality of optical sources 20(1) to 20(n) respectively are provided to successively extend in a longitudinal direction of a band-shape diffusion plate 41, the emi...

Zusammenfassung:	There is provided an illuminating device in which a plurality of emission regions W(1) to W(n) corresponding on a one-to-one basis to a plurality of optical sources 20(1) to 20(n) respectively are provided to successively extend in a longitudinal direction of a band-shape diffusion plate 41, the emission region is arranged to overlap the other emission region adjacent in the longitudinal direction in a predetermined range of both the side portions and a control unit 30 controls lighting-up/lighting-out and an emission intensity of each of the optical sources based upon a schedule. In the schedule SC, for realizing a temporal change in an average illuminance of the entire diffusion plate 41 in each time point in the middle of carrying out the performance of light, a lighting-up/lighting-out state of the plurality of optical sources 20(1) to 20(n) and an emission intensity of the optical source to be lit up are set.
