ABSTRACT:
Disclosed is a lamp driving control apparatus for a washing machine and a control method therefor which control operation of a lamp in accordance with a door opening/closing operation in the washing machine. A lamp driving control apparatus resides within washing machine which washing machine includes a main body, a door mounted to the main body, a door motor for providing power to open and closed the door, and a lamp that is turned on when the door is opened in order to illuminate an interior of the main body. The control apparatus includes: a door open sensor for sensing whether the door is opened by a predetermined angle corresponding to a fully opened door; and a controller for turning on the lamp when the door is opened beyond the predetermined angle corresponding to the fully opened door. A lamp driving control method for the washing machine includes the steps of: determining whether the door is opened beyond a predetermined angle corresponding to a fully opened door; turning on the lamp for a predetermined time when the door is fully opened, or turning off the lamp when the door is not fully opened; and turning off the lamp when a predetermined time has lapsed after turning on the lamp. Accordingly, power consumption waste caused by the lamp being driven when the door is not fully opened is avoided.
