Abstract
An illumination device for a vehicle headlamp that provides headlamp levelling. The illumination device includes a primary light module configured to emit light in a main direction, wherein the primary light module is rotatable around a rotation axis; a moveable shield cover for shielding the primary light module; and a motion device for moving simultaneously the primary light module around the rotation axis and the shield cover with respect to each other between (a) non-illuminating positions, wherein the shield cover is in front of the primary light module, and (b) illuminating positions, wherein the shield cover is moved away from the light path of the light module. In each illuminating position, the primary light module is in a defined angular position of a determined operating angular range around the rotation axis to project the light distribution in different angular positions in front of the illumination device for headlamp levelling.
