Kind Code:
A
Abstract:
PURPOSE: To set an illumination control system to the warning state against an intruder without deliberately taking an action when going out.
CONSTITUTION: Human body detecting sensors 11, 12 have detection areas D1, D2 near the entrance of a house. A controller 2 detects the locked/unlocked state of an electrical lock installed on a vestibule door via a controller 8. If the electrical lock is locked when the human body detecting sensors 11, 12, detect a person, the controller 2 lights a porch lamp 32. When the porch lamp 3 is lighted, it greets a homecoming family or a visiting guest, and it gives an impression that the family stays inside to a suspicious person to menace him.
