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: 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 control unit for controlling a turn-on operation of the illumination device, and a terminal through which manipulation information of the illumination device is inputted by a user. The control unit includes an information extracting unit for extracting illumination information, within a period between a first moment prior to a falling-asleep time of the user and a second moment after a wakeup time of the user, from manipulation information and operation information of the illumination device stored in a memory unit, and an information transceiver unit for transmitting and receiving the illumination information to and the terminal. The terminal includes a terminal transceiver unit for transmitting and receiving the illumination information to and from the control unit, a display unit for displaying the illumination information received through the terminal transceiver unit and an input unit by which the manipulation information is inputted.
