    Abstract: A lighting system includes: a wireless communication device that transmits a test signal; luminaires that measure a signal strength of the test signal upon receipt and transmit signal strength information on the signal strength to the wireless communication device; and a determining unit that determines a condition of the lighting system based on the signal strength or the signal strength information. The determining unit: determines the condition of the lighting system to be acceptable upon confirming transmission of the signal strength information by all luminaires and unacceptable upon failing to confirm transmission of the signal strength information by at least one luminaire; or determines the condition of the lighting system to be acceptable when each signal strength measured by all luminaires exceeds a reference value and unacceptable when the signal strength measured by at least one luminaire is less than or equal to the reference value.

    Abstract: A second communication unit of a wireless controller transmits a first signal to luminaires, the first signal instructing the luminaires to respond to a request from the wireless controller. A control unit (i) receives a response to the first signal sent from the luminaires, (ii) when there is a first group including a luminaire that has responded to the first signal, and a second group including at least one luminaire that has not responded to the first signal, assigns the luminaire in the first group as a relay luminaire, and (iii) transmit a second signal to the relay luminaire, the second signal instructing the relay luminaire to wirelessly communicate with the at least one luminaire in the second group via the second communication unit. The relay luminaire that has received the second signal wirelessly communicates with the at least one luminaire in the second group via a first communication unit.
