摘要

The device has a presence warning device (2) for setting a lamp (1) for a long time operation, when a person (4) is detected in a detecting region. A dimming device (3) is provided to control temporal development of an illumination level of the lamp according to a preset program, where the preset program of the dimming device is modifiable.
