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: 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: An illumination system includes a light projection device, an illuminance measurement unit, a lighting device, and a control device. The light projection device projects an image to a space. The illuminance measurement unit measures an illuminance value of a location where the illuminance measurement unit is placed in the space. The lighting device has a dimming function for illuminating the location in the space with a brightness. The control device includes an illuminance setting unit, a difference calculation unit, and an illumination light adjusting unit. The illuminance setting unit sets an illuminance value of the location. The difference calculation unit calculates a difference between the illuminance value set by the illuminance setting unit and the illuminance value measured by the illuminance measurement unit. The illumination light adjusting unit adjusts a brightness of the lighting device such that the difference calculated by the difference calculation unit is reduced.

Abstract: An illumination apparatus includes: a case having an opening portion; a light source disposed in the case and including a plurality of light-emitting elements; a light diffuser which is disposed in the opening portion, and diffuses and transmits light emitted from the plurality of light-emitting elements; and a controller that controls light emission from the light source. The controller: controls light emission from the plurality of light-emitting elements to project an image on the light diffuser, the image changing with time; and when changing the light emission from the plurality of light-emitting elements changing the image, controls the light emission from the light source to keep a change in at least one of (i) a light amount, (ii) a color temperature, and (iii) a spectral distribution of light emitted from the illumination apparatus within a predetermined range.

Abstract: A lighting apparatus includes: a case having an opening portion; a light emission panel in the case, the light emission panel having a light emission surface which emits light having a light distribution which dynamically changes; and a light distribution modification panel in the opening portion and having a distribution-modified light emission surface which modifies the light distribution of the light to emit light having a modified light distribution. The light emission panel emits, as the light having the light distribution, light having at least one of a luminance distribution and a chromaticity distribution of a first image to be presented on the light emission surface. The light distribution modification panel diffuses and transmits the light emitted from the light emission surface to emit light such that the at least one distribution of a second image to be presented on the distribution-modified light emission surface is changed to a blurred state.

Abstract: A luminaire includes a light source; a storage for storing sound wave data which is predetermined; a microphone that detects sound; a communication circuit that communicates with a master controller; and a controller that performs pairing of the luminaire with the master controller via the communication circuit. The controller obtains sound wave data from the sound detected by the microphone, and performs the pairing when the sound wave data obtained matches the sound wave data stored in the storage.
