Abstract:
1. A wake-up system comprising: an illumination apparatus which irradiates wake-up light; a control apparatus which controls output of the wake-up light irradiated from the illumination apparatus, and an interface apparatus which is operated by a user to input at least a wake-up time, wherein the illumination apparatus comprises an output variation apparatus which varies output of the wake-up light to be irradiated, and a color temperature variation apparatus which varies color temperature of the wake-up light, and wherein the control apparatus comprises a light output control unit which controls the output variation apparatus so as to increase the output of the wake-up light irradiated from the illumination apparatus from a wake-up operation start time to the wake-up time input by the user, and a color temperature control unit, wherein time from the wake-up operation start time to the wake-up time includes in sequential order the wake-up operation start time, a second time, a first time and the wake-up time, wherein the first time is defined after a first predetermined time period after the wake-up operation start time, wherein the second time is defined before a second predetermined time period before the first time, wherein a remainder time period is defined from the first time to the wake-up time, wherein the second predetermined time period is shorter than the first predetermined time period, wherein the color temperature control unit controls the color temperature variation apparatus such that color temperature of the wake-up light in the remainder time period becomes higher than the color temperature of the wake-up light in the second predetermined time period, and wherein the color temperature control unit raises monotonously the color temperature of the wake-up light from the wake-up operation start time to the first time and from the first time to the wake-up time input by the user, and increases the color temperature of the wake-up light so that a rate of increase per unit time of the color temperature of the wake-up light from the first time to the wake-up time becomes larger than a rate of increase per unit time of the color temperature of the wake-up light from the wake-up operation start time to the first time.
