PROBLEM TO BE SOLVED: To provide a low-cost awakening device exerting an excellent awakening effect of causing no incongruity sense by reproducing a state of sunrise in the natural world with high accuracy, and prompting a sleeper to comfortable awakening.SOLUTION: An awakening device includes: a lower light source obliquely upward or horizontally sideways illuminating a sleeper; an upper light source obliquely downward illuminating the sleeper; and a light source control part controlling illuminations and color temperatures of the lower light source and the upper light source in a state that the illuminations and the color temperatures are associated to simulate a state of sunrise. Preferably, the light source control part has: first control means maintaining an extinction state or a low-illumination state of the lower light source, and maintaining an extinction state of the upper light source; second control means operating subsequently to the first control means, and gradually increasing the illumination of the lower light source; third control means operating subsequently to the second control means, gradually increasing the illumination of the lower light source, turning on the upper light source, and gradually increasing the illumination; and fourth control means operating subsequently to the third control means, gradually reducing the illumination of the lower light source, and gradually increasing the illumination of the upper light source. |
