Abstract: A lighting control system controls a light source that emits light to a space in which subjects stay. The lighting control system includes: an communication interface that obtains stay schedule information indicating scheduled periods in an operation period after a first time and before a second time later than the first time, the scheduled periods being periods during each of which a corresponding one of the subjects is to stay in the space; and a processor that creates an illumination schedule for causing the light source to emit the light, based on the stay schedule information, and causes the light source to emit the light according to the illumination schedule created. The processor creates, based on the stay schedule information, the illumination schedule for causing the light source to emit the light during a period including a scheduled period common to at least two of the subjects.

Abstract: In an illumination apparatus, a control unit starts lighting of a light source at a first time before a wake-up set time and executes a first control pattern to increase a dimming ratio of the light source from the first time to a second time determined based on the wake-up set time and a second control pattern to further increase the dimming ratio of the light source from the second time to a third time determined based on the wake-up set time. When a change curve of the dimming ratio in the first control pattern and the second control pattern is applied to a function represented by the equation: Y(t)=d+(a−d)/(1+(t/c)b), the time c becomes closer to the second time than the first time in the first control pattern, and becomes closer to the second time than the third time in the second control pattern.

Abstract: An illumination system includes: an illumination device; a time setter that sets a target time; and a controller that controls a color temperature of light emitted by the illumination device. The controller determines a target color temperature according to the target time, and causes the color temperature of the light emitted by the illumination device to be the target color temperature at the target time.

Abstract: A lighting device includes: a light source switchable between illumination modes; a human detector which detects a person in a detection area in an illumination area of the light source; an ID reader which wirelessly reads an identification stored in an RF tag in a read area corresponding to the detection area; and a controller communicably connected to the light source, the human detector, and the ID reader. The controller obtains from the human detector human detection information indicating that one or more persons are present, obtains from the ID reader one or more identifications read by the ID reader when the human detector detects the one or more persons, and applies one mode of the illumination modes to the light source based on the human detection information and one or more identifications obtained, and the light source performs illumination in the applied mode.

Abstract: An illumination system includes a plurality of illumination apparatuses including a sleeping location illumination apparatus provided near a sleeping location. Each of the illumination apparatuses has a light source configured to irradiate an illumination light, a control unit configured to control lighting of the light source, and a transceiver configured to transmit and receive a control signal including a lighting signal for lighting the light source. A control unit of at least one of the illumination apparatuses turns on the light source before a preset wake-up time and controls the transceiver to transmit the control signal to another illumination apparatus.

Abstract: A cubicle unit includes a first illumination apparatus, a second illumination apparatus, a sensor, and a controller. When a brightness sensed by the sensor is a predetermined brightness or less, the controller causes the second illumination apparatus to emit light having a first color temperature lower than a color temperature of light emitted by the first illumination apparatus. When the brightness sensed by the sensor is greater than the predetermined brightness, the controller causes the second illumination apparatus to emit light having a second color temperature lower than the first color temperature.
