<p>PROBLEM TO BE SOLVED: To provide an illuminating device which saves a lot of labor in order to obtain desired illuminance and which facilitates confirmation work of setting illuminance and which is capable of easily obtaining desired illuminance. SOLUTION: This illuminating device comprises an illuminance sensor 1 for detecting illuminance of an irradiated surface, a control part 2 for controlling the light output of an illumination load 3 when receiving the output of the illuminance sensor 1, and an illuminance setting switch SW4 for setting target illuminance of the irradiated surface. In addition, this illuminating device has an adjustment mode in which the time needed for changing the light output of the illumination load 3 is short, and also has a normal mode in which the time needed for changing the light output of the illumination load 3 is longer than that of the adjustment mode. External triggers start the adjustment mode.</p> |
