To solve such a problem that an initial light intensity that varies according to each LED and the effect of change with age in the light intensity cannot be eliminated by the correction of a decrease in the light intensity of an LED due to change with age carried out based on data of average illumination intensity and accumulated illumination time.
A refrigerator includes: an LED (91) provided on a wall of a storage chamber, and for emitting light toward the interior of the chamber; an LED drive (103) for supplying power to the LED; an illuminance sensor (92) for measuring the illuminance of the LED; a memory (102a) for storing an illuminance set value of the LED; and a control unit (10) for adjusting the illuminance of the LED based on the illuminance of the LED measured by the illuminance sensor and the illuminance set value.
