PROBLEM TO BE SOLVED: To provide a lighting fixture capable of improving the reliability of wireless communication.SOLUTION: A lighting fixture comprises: a light source module; a power supply device 29; a wireless module 27; and a wireless control unit 28. The light source module comprises a light source. A lighting circuit controls the light source module. The wireless module 27 transmits and receives wireless signals. The wireless control unit 28 controls the power supply device 29 in response to the wireless signal received by the wireless module 27. The lighting fixture is configured such that a wireless signal cutoff member that does not transmit the wireless signal is not disposed at a distance that is an integer multiple of a quarter of a wavelength of the wireless signal transmitted from the wireless module 27.SELECTED DRAWING: Figure 1 【課題】無線通信の信頼性を向上した照明器具を提供する。【解決手段】照明器具は、光源モジュールと、電源装置29と、無線モジュール27と、無線制御部28とを備える。光源モジュールは、光源を備える。点灯回路は、光源モジュールを制御する。無線モジュール27は、無線信号を送受信する。無線制御部28は、無線モジュール27で受信した無線信号に応じて電源装置29を制御する。照明器具は、無線モジュール27から送信される無線信号の波長の１／４の整数倍の距離には、無線信号が透過しない無線信号遮断部材が配置されていない。【選択図】図１
