To make it possible to prevent photosensitivity seizures or the like by synchronizing blinking of a plurality of lighting devices having overlapping lighting areas without exchanging synchronization signals.SOLUTION: Alarms 12 (12-1) to 12 (12-3) are installed in rooms or the like of a residential building 11, and when a fire is detected, output a fire alert and transmit a fire transfer signal. Lighting devices 10 (10-1) to 10 (10-4) receive the fire transfer signal from the alarms 12 (12-1) to 12 (12-3) and start blinking for prompting evacuation guidance. The lighting device 10 (10-1) detects and synchronizes the blinking of the other lighting device 10 (10-2) whose lighting area overlaps during the blinking. For example, if the lighting device 10 (10-1) detects the start of lighting in the blinking of the other lighting device 10 (10-2) during a turn-off time T2 of a blinking cycle T, the lighting device synchronizes its own blinking with the blinking of other lighting device 10 (10-2), by starting lighting with a delay of the blinking cycle T from that lighting start time point.SELECTED DRAWING: Figure 1 【課題】同期信号をやり取りすることなく照明エリアが重複する複数の照明装置の点滅を同期させて光過敏性発作などを防止可能とする。【解決手段】警報器１２（１２－１）～１２（１２－３）は住宅１１の部屋等に設置され、火災を検出した場合に火災警報を出力するとともに火災移報信号を送信する。照明装置１０（１０－１）～１０（１０－４）は、警報器１２（１２－１）～１２（１２－３）からの火災移報信号を受信して避難誘導を促すために点滅を開始する。照明装置１０（１０－１）は、点滅中に照明エリアが重複する他の照明装置１０（１０－２）の点滅を検出して同期させる。例えば、照明装置１０（１０－１）は、点滅周期Ｔの消灯時間Ｔ２に他の照明装置１０（１０－２）の点滅における点灯開始を検出した場合、当該点灯開始時点から点滅周期Ｔだけ遅延して点灯を開始することで、自己の点滅を他の照明装置１０（１０－２）の点滅に同期させる。【選択図】図１
