<p>PROBLEM TO BE SOLVED: To provide a lighting device control apparatus which reduces power consumption of a lighting device while securing visibility for a visual worker.SOLUTION: A lighting device control apparatus 200 comprises: a visual worker presence/absence acquisition part 201 for acquiring a sensor signal representing the presence/absence of a visual worker; and a storage part 211. The storage 211 stores image display device luminance data representing luminance in the case where each image display device is watched from each of work desk, for each luminance setting of the image display device and stores desktop illuminance data representing illuminance on the work desk for each setting of brightness of a lighting device. The lighting device control apparatus further comprises: a recommended illuminance calculation part 206 for calculating recommended illuminance on the work desk on the basis of the image display device luminance data 204; a lighting device control pattern derivation part 207 for deriving a setting of brightness for each lighting device on the basis of the sensor signal, the desktop illuminance data 205 and the recommended illuminance; and a lighting device control pattern output part 208 for outputting the setting of brightness to a lighting device regulation part 209.</p> |
