Lighting Control System, Lighting System, And Lighting Control Method
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.

- 1. A lighting control system that controls a light source that emits light to a space in which subjects stay, the lighting control system comprising:
a 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, wherein the processor creates, based on the stay schedule information, the illumination schedule for (i) allowing the subjects to achieve respective target light-receiving times that are predetermined and for which the subjects receive the light emitted by the light source, (ii) minimizing a time for which the light source emits the light, (iii) causing the light source to emit the light during a period including a scheduled period common to at least two of the subject, and (iv) causing the light source not to emit the light during a period including a scheduled period common to less than two of the subjects.
- 13. A lighting control method executed by a lighting control system that controls a light source that emits light to a space in which subjects stay, the lighting control method comprising:
obtaining, by a communication interface, 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; creating, by a processor, an illumination schedule for causing the light source to emit the light, based on the stay schedule information obtained by the communication interface; and controlling, by the processor, the light source according to the illumination schedule created by the processor, wherein in the creating, the processor creates, based on the stay schedule information, the illumination schedule for (i) allowing the subjects to achieve respective target light-receiving times that are predetermined and for which the subjects receive the light emitted by the light source, (ii) minimizing a time for which the light source emits the light, (iii) causing the light source to emit the light during a period including a scheduled period common to at least two of the subject, and (iv) causing the light source not to emit the light during a period including a scheduled period common to less than two of the subjects.
