Claim:
An apparatus for controlling a lamp of a refrigerator, comprising: a dispenser provided on a refrigerator door, wherein the dispenser comprises: an operation lever for adjusting a discharge amount of ice or water; a rotary member that includes a rotary shaft supported by side walls of the dispenser and a connection part that extends from the rotary shaft, and a duct door, coupled to the connection part, for selectively opening and closing an ice duct based on movement of the rotary member and the duct door for being removably combined with the rotary member; at least one lamp installed on a side of the rotary member to illuminate the dispenser, wherein the at least one lamp is installed on a surface of the rotary member to illuminate an inner side of the dispenser when the duct door closes the ice duct; a sensor for sensing a surrounding brightness of the refrigerator; a control unit for controlling on/off operation of the at least one lamp, wherein the control unit causes the rotary member to be swiveled in a direction, so that the ice duct is opened by the duct door when the operation lever is operated, wherein the control unit is capable of varying a driving control signal such that a brightness of the at least one lamp is changed in response to an output of the sensor; and a rotation restraint piece provided on a surface of the duct door to extend farther from the duct door higher than a height of the at least one lamp to prevent fracture of the at least one lamp when the duct door is opened.
