ABSTRACT:
In a wake-up apparatus for waking up a sleeper by light stimulus, it wakes the sleeper comfortably without feeling glare. A lighting device has a first lighting unit at a position that a light emitting face cannot be observed directly by the sleeper, and a second lighting unit at a position that a light emitting face can be observed directly by the sleeper. A control device activates the lighting device a predetermined time before a preset wake-up time so as to vary illuminance of light emitted from the lighting device in an order of low illuminance, middle illuminance and high illuminance, to light only the first lighting unit in a low illuminance condition and a middle illuminance condition, and to light both of the first lighting unit and the second lighting unit in a high illuminance condition, and quickly varies from the middle illuminance condition to the high illuminance condition.
