Abstract: PURPOSE: A dimmer for a car audio cassette is provided. CONSTITUTION: In a dimmer for a car audio cassette, when the car audio cassette is not operated, a display window is turned off by intercepting power supplied to a lamp(500). When the car audio cassette starts to be operated in the daytime, a dimming level is maintained to a predetermined value, by providing DC power of a predetermined level from a battery(100) to the lamp(500), and turning on the display window. When the car audio cassette is operated in the night time, the dimming level of the display window is variably controlled by distinguishing DC power paths from a car dimming unit(400), and variably adjusting a size of the fed-back and inputted power. As a result, when the driver drives the car, operating the car audio cassette in the night time, the fatigue of the driver by excessive brightness of the display window is removed.
