摘要： Illumination device (10, 20) for a vehicle headlamp, wherein the illumination device (10, 20) provides headlamp levelling for a vehicle headlamp, the illumination device (10, 20) comprises:
- at least one primary light module (100) configured to emit light in a main direction (X), wherein the primary light module (100) is rotatable around a rotation axis (RA),
- a moveable shield cover (200) for shielding the primary light module (100),
- a motion device (300) for moving simultaneously the primary light module (100) around the rotation axis (RA) and the shield cover (200) with respect to each other between
- non-illuminating positions (P1a, P1b, P2a) of the primary light module (100), wherein the shield cover (200) is in front of the at least one primary light module (100), and
- illuminating positions (P3a, P4a) of the light module (100), wherein the shield cover (200) is moved away from the light path of the light module (100)

wherein in each illuminating position (P3a, P3b, P4a) the at least one primary light module (100) is in a defined angular position of a determined operating angular range around the rotation axis (RA) in order to project the light distribution in different angular positions in front of the illumination device (10, 20) to allow a headlamp levelling for a vehicle headlamp.

摘要： Illumination device (10) for a motor vehicle headlamp, wherein the illumination device (10) comprising:
- at least one light module (20) configured to illuminate light along a light path in a main direction (X),
- a movable lower light guide element (100) and a movable upper light guide element (200),
- a motion device for a movement of the lower and upper light guide element (100, 200) with respect to each other between
- a closed position (PI), wherein the lower and upper light guide element (100, 200) are
- as seen in the main direction (X) - in front of the at least one light module (20) at least partially blocking the light path of the at least one light module (20), wherein the lower and upper light guide element (100, 200) are configured to emit light in the main direction (X), when in the closed position (PI), and
- an opened position (P2), wherein the lower and upper light guide element (100, 200) are moved away from the light path of the at least one light module to unblock the light path of the at least one light module (20),
while maintaining their spatial orientation,
- a frame (600), which is stationary in relation to the movement of the lower and upper light guide element (100, 200), wherein the motion mechanism is mounted on the frame (600).
