Abstract: A lighting system includes a wireless controller, luminaires each configured to communicating with the wireless controller, and a storage. The wireless controller classifies a first luminaire among the luminaires, which is able to communicate using first transmission power, into a first group and stores the first luminaire on the storage, and classifies a second luminaire among the luminaires, which is able to communicate using second transmission power greater than the first transmission power, into a second group and stores the second luminaire on the storage.

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.
