Abstract: An illumination control method includes: causing an illumination apparatus to illuminate a predetermined space with light; and controlling at least one of a color temperature of light which the illumination apparatus emits and an illuminance of the light which the illumination apparatus emits in the predetermined space, to cause an integrated value to be at least 10 ?W·h/cm2. The integrated value is a value resulting from integrating time and an effective amount of melatonin during a first time frame from 5:00 to 14:00.

Abstract: An illumination system includes a light source capable of emitting biorhythm control light, a controller that controls a lighting state of the light source, and a manipulation apparatus. The controller executes an introduction mode in which the illuminance of the biorhythm control light is set by gradually increasing or decreasing illuminance of the light source over time, and a stationary mode in which the illuminance of the light source is constantly maintained at the illuminance of the biorhythm control light.

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: A lighting system includes a light source unit; an irradiation controller that forms a first area in a space by causing the light source unit to emit first light according to a first irradiation schedule, and simultaneously with the formation of the first area, forms a second area in the space by causing the light source unit to emit second light according to a second irradiation schedule; a communicator that acquires health condition information indicating the health condition of a user; a judgment unit that judges whether the user is a first subject targeted for irradiation with the first light or a second subject targeted for irradiation with the second light, on the basis of the acquired health condition information; and a presentation unit that presents whether the user is the first subject or the second subject, on the basis of the judgment.

Abstract: A light treatment apparatus is an example of a light-emitting apparatus including a white light source, a blue light source, and a controller. The controller performs (i) constant light emission control for causing each of the white light source and the blue light source to emit light at constant brightness, and (ii) light reduction control which is performed after the constant light emission control so as to cause each of the white light source and the blue light source to reduce light intensity. The controller causes the blue light source to start reducing light intensity before causing the white light source to start reducing light intensity, and turns on the blue light source at the same time as or before turning on the white light source.

Abstract: A lighting apparatus includes: a lighting device; and a controller which receives from a lighting setter, an instruction for causing the lighting device to operate in a predetermined mode, causes the lighting device to operate in the predetermined mode according to first control content, and subsequently receiving the instruction, causes the lighting device to operate in the predetermined mode according to second control content which is modified from the first control content based on first subjective information input to the lighting setter, the first subjective information indicating feedback of a user on the first control content.

Abstract: A lighting system includes: an illumination light source which irradiates a user with illumination light; a user interface which receives a user operation; a controller which controls an amount of light of the illumination light source and an irradiation period of the illumination light source; and a storage which stores characteristic information having a negative correlation between the amount of light and the irradiation period.
