PURPOSE:To obtain an indication controller for a refrigerator, in which the brightness of a LED and the like for indicating the inside temperature or the like of the refrigerator will never give a user uncomfortableness coming from the brightness that is apparently too bright at night different from daytime. CONSTITUTION:The controller is provided with a day and night detecting means or a light sensor 8 for detecting a difference between daytime and night. A light emitting luminance control means 9, controlling the luminance of a LED 3 or an indicating means indicating a temperature and the like in a refrigerator based on the detection of the light sensor 8, is constituted of a microcomputer 1 and the like while light is emitted from the LED 3 so as to be bright in day time and dark at night to prevent too bright luminance at night. |
