Abstract
In determining luminance, a location of human presence is referred. An infrared sensor detects the human presence in its proximity. The infrared sensor's effective detecting region includes a first region and a second region. The first region is farther from the infrared sensor than the second region is. And the first region surrounds the second region. Second, a first luminance is set for human presence within the first region; a second luminance is set for human presence within the second region; and a third luminance is set for nonoccurrence of human presence within both the first region and the second region. In addition, the second luminance is higher than the first illuminance, and the first illuminance is higher than the third illuminance. Third, an illuminating device is activated by applying the first luminance, the second luminance, or the third luminance, in response to a location of the detected human presence.
