<p>PROBLEM TO BE SOLVED: To provide an illumination control device that can easily and simply change the illumination level of the illumination apparatus based on the detected value of the illumination sensor and perform correctly the illumination fixing control even when the reflection factor or reflection coefficient of the floor by the light flux of the illumination apparatus has changed dramatically in the illumination control device which is structured to make illumination fixing control of the illumination apparatus based on the detected value of the illumination sensor by detecting the reflection light from the floor using the sensor. SOLUTION: The illumination control device comprises an illumination sensor 16, an illumination adjusting means for adjusting the output of the illumination apparatus, a first memory means 22 for storing the target illumination value, and a control means 24 for controlling the illumination adjusting means so as to coincide the target illumination value with the illumination value detected by the illumination sensor. A second memory means 26 for storing any level of illumination under illumination control by the control means is provided, and a switching means 28 for switching is provided so that the illumination adjusting means may control the output of the illumination apparatus in accordance with the level of illumination stored in the above second memory means.</p> |
