Claim Text:
1. An apparatus for controlling a headlamp, the apparatus comprising: a rotating shield including a first shield protrusion portion, including a plurality of protrusions formed in a direction of a rotation axis of a rotatable body and a second shield protrusion portion disposed on a side of the first shield protrusion portion; a sensor detecting a rotation angle of the rotating shield and a light distribution pattern of a vehicle based on the rotation angle of the rotating shield; and a controller rotating the rotating shield around a central axis of a first angle toward the first shield protrusion portion or around a central axis of a second angle toward the second shield protrusion portion based on the sensor detections, outputting the detected light distribution pattern to perform a flashing pattern, wherein the rotating shield comprises one or more flashing regions for performing the flashing pattern, and each of the flashing regions is formed in a portion adjacent to the first shield protrusion portion or the second shield protrusion portion, and wherein the rotating shield rotates around the central axis in a direction of one of the flashing regions toward which the rotating shield is rotated by the smaller angle of the first and second angles and a portion of the light distribution pattern is blocked by an edge of the first shield protrusion portion or an edge of the second shield protrusion.
