Abstract: A lighting system includes a plurality of lighting devices and a terminal. The terminal includes a display screen, an input unit, a communication unit, and a device controller. The device controller (i) obtains, from outside the terminal, setting information including attribute information indicating at least one attribute regarding an installation location of each of the plurality of lighting devices, (ii) associates each of the plurality of lighting devices with any of the at least one attribute indicated by the attribute information included in the obtained setting information according to a dialog with an operator using the display screen and the input unit of the terminal, so as to classify the plurality of lighting devices under groups.

Abstract: A lighting system includes lighting devices and a terminal. The terminal includes a display screen, an input unit, a wireless transmitter which transmits a radio signal, a communication unit which wirelessly transmits a control command to one of a communication address and a logical address for at least one of the lighting devices, specifying the one of the communication address and the logical address, and a controller which displays, on the display screen, icons respectively corresponding the lighting devices, and when an instruction for selecting any one of the icons has been received by the input unit, causes the wireless transmitter to transmit a radio signal indicating predetermined information. When one of the lighting devices which corresponds to the selected icon has received the radio signal, the lighting device transmits the communication address assigned to the lighting device itself to be used for communication with the communication unit.

Abstract: An electrical apparatus management system includes electrical apparatuses installed in a building, a management device that communicates with each of the electrical apparatuses, and an operation terminal that communicates with each of the electrical apparatuses. The operation terminal transmits management address information individually to each of the electrical apparatuses using radio having directivity, the management address information being information to be assigned individually to each of the electrical apparatuses. Each of the electrical apparatuses has an own specific address, stores the management address information transmitted from the operation terminal, and transmits the specific address and the management address information.

Abstract: A lighting fixture includes a transceiver, a receiver, a storage, and a controller. The transceiver receives a radio command from a radio remote controller for operating the lighting fixture. The receiver receives an infrared command from an infrared remote controller for operating the lighting fixture. The storage stores identification information of the radio remote controller. The controller, if the identification information is stored in the storage, accepts a radio command that includes identification information same as the identification information stored in the storage, among radio commands received by the transceiver, and ignores the infrared command received by the receiver, and if no identification information is stored in the storage, accepts the infrared command received by the receiver.

Abstract: A lighting device which changes a hue of light which the lighting device outputs, by changing a brightness proportion between a first light source and a second light source, the lighting device including: a light source which includes the first light source and the second light source, storage which stores control values for causing the light source to output light having a same hue as a hue of light which is output from a light source included in another lighting device; a current adjuster which calculates a first current value, and a second current value, using the control values; and a power source which supplies a first current to the first light source according to the first current value and supplies a second current to the second light source according to the second current value.

Abstract: A pairing method for causing lighting devices to store identification information of a radio remote controller serving as a master device is provided. The method includes: transmitting a pairing command including the identification information of the radio remote controller repeatedly on a temporary basis by the radio remote controller; determining, for each of the lighting devices, whether or not the lighting device is in an initial state in which identification information of a master device is not stored in the lighting device, at power on; storing the identification information included in the pairing command, if the paring command is received when it is determined that the lighting device is in the initial state in the determining; and causing the lighting device in which the identification information of the master device is stored to operate according to a radio command including the identification information of the master device.
