Abstract: A lighting device includes: a communication unit configured to wirelessly communicate with a wireless device provided externally; a command receiver that receives a command from outside; a light emitter including a light source; and a controller connected to the communication unit, the command receiver, and the light emitter. The command receiver receives a wireless device specifying command that specifies the wireless device with which the communication unit is to wirelessly communicate. The controller tests wireless communication with the wireless device via the communication unit based on the wireless device specifying command received, obtains communication reliability information regarding the reliability of the wireless communication, and causes the light emitter to perform at least one of flashing, dimming, and toning based on the communication reliability information obtained.

Abstract: Luminaires in a lighting system have mutually different addresses. A setting device includes a communication unit that transmits an address request signal at a first transmission power level and a control unit that determines whether a total number of the addresses transmitted from one or more of the luminaires in response to receiving the address request signal is within a target range. The control unit instructs the communication unit to transmit the address request signal at a transmission power level different from the first transmission power level when the total number of the addresses is outside the target range, and executes pairing of the one or more of the luminaires that responded to the address request signal with a wireless controller when the total number of the addresses is within the target range.
