LIGHTING APPARATUS AND ILLUMINATION SYSTEM

To reduce installation cost, while keeping reliability of lighting during electric outage and notification of occurrence of a specific event.SOLUTION: A lighting apparatus 1 includes a light source 10, a power failure detection circuit 113, a communication unit 115 and a control circuit 114. The power failure detection circuit 113 detects electric outage of an AC power supply 9. The communication unit 115 receives a detection signal, indicating detection of specific event (fire disaster) other than electric outage, from a receiver (communication device). The control circuit 114 controls lighting state of the light source 10. When the power failure detection circuit 113 detects power failure, the control circuit 114 controls the light source 10 to be lighted in first lighting state. When the communication unit 115 receives the detection signal, the control circuit 114 controls the light source 10 to be lighted in a second lighting state different from the first lighting state.SELECTED DRAWING: Figure 3 【課題】停電時の照明及び特定の事象の発生の報知に関する信頼性を保ちつつ、設置コストの削減を図ること。【解決手段】照明器具１は、光源１０と停電検出回路１１３と通信部１１５と制御回路１１４とを備える。停電検出回路１１３は、交流電源９の停電を検出する。通信部１１５は、停電以外の特定の事象（火災）の検出を示す検出信号を、受信機（通信装置）から受信する。制御回路１１４は、光源１０の点灯状態を制御する。制御回路１１４は、停電検出回路１１３が停電を検出すると、光源１０を第１点灯状態で点灯させるように制御する。また、制御回路１１４は、通信部１１５が検出信号を受信すると、光源１０を第１点灯状態とは異なる第２点灯状態で点灯させるように制御する。【選択図】図３
