<P>PROBLEM TO BE SOLVED: To provide an illumination device of high convenience capable of adjusting various illumination intensities in an awakening mode. <P>SOLUTION: A control unit of an illumination device controls optical output of a light source, and has a plurality of awakening modes changed during a period during which illumination intensity by the light source reaches prescribed illumination intensity. The control unit detects whether a control signal included in a predetermined control signal group was input when the illumination device was operating in a standard awakening mode which controls the illumination intensity by the light source to reach second illumination intensity higher than first illumination intensity among a plurality of awakening modes (S15). When the control signal included in the predetermined control signal group is input (S15: YES), the control unit switches an operation mode so that the illumination device operates in an awakening mode corresponding to the input control signal among the plurality of awakening modes (S18, S19). <P>COPYRIGHT: (C)2013,JPO&INPIT |
