To solve a problem in which, in a conventional lighting device that detects that a person has actually moved and automatically turns on a lighting fixture, a crime prevention function cannot be exerted if an intruder actually does not invade an indoor room, and the intruder itself cannot be prevented in advance, and, for example, even when an intruder invades the indoor room while the indoor is unmanned, it is not possible to determine from the outside such as a neighbor whether the lighting is performed by detecting a family member or by detecting the intruder, and the crime prevention function is not always expensive.SOLUTION: A predetermined one of a plurality of lighting fixtures installed in various places in a room is automatically turned on for a predetermined time, and another lighting fixture adjacent to the turned-on lighting fixture is turned on before the lighting fixture that has been turned on first is turned off, and therefore, it is possible to create a situation as if a person is actually moving.SELECTED DRAWING: Figure 1 【課題】実際に人が移動したことを検知して自動的に照明器具を点灯させる従来の照明装置では、実際に侵入者が屋内に侵入した後でなければ防犯機能を発揮せず、侵入者の侵入自体を事前に防止することはできない。また、例えば屋内が無人状態で侵入者が屋内に侵入しても、家人を検知しての点灯か侵入者を検知しての点灯かを隣人など外部から判断することができず、防犯機能は必ずしも高いとは言えない。【解決手段】屋内の各所に設置された複数個の照明器具のうちの所定の１個の照明器具を自動的に所定時間点灯させ、その点灯させた照明器具に隣接する他の照明器具を、先に点灯させた照明器具が消灯する前に点灯させることによって、人が実際に移動しているかのような状況を演出するようにした。【選択図】 図１
