PURPOSE:To save energy by controlling the illumination energy source inside space instantaneously or after a certain time when it detects the unmanning inside the space based on ID discrimination. CONSTITUTION:In case of OK on ID discrimination, for a controller 3, the invasion monitor mode by an invasion sensor 4 is finished, and it erects a stay- in-room flag, which shows that the person discriminated by ID has entered the room. Next, at exit from the room, a card reader 1A on the side of exit reads the ID card, and at the time of OK on reference of ID NO., an electric lock 2b is temporarily unlocked and an OK lamp lights temporarily, and also the person goes out of the room, so it controls the stay-in-room flag to go out, and the person of OK on ID discrimination leaves the room to outside. At every exit, the controller 3 judges whether the stay-in-room flags of other persons are put up or not, and when all the flags are not put up after remaining persons go off, it darkens some of ceiling light 5 for a certain time, and extinguishes the illumination at exit. |
