An illumination device (10) for a vehicle headlamp, wherein the illumination device (10) provides headlamp levelling for a vehicle headlamp, the illumination device (10) comprising:
- at least one primary light module (100) configured to emit light along a light path in a main direction (X) in order to project a light distribution in front of the illumination device (10), in particular onto a road, wherein the at least one primary light module (100) is rotatable around a rotation axis (RA);
- a moveable shield cover (200) for shielding the at least one primary light module (100) in order to prevent the at least one primary light module (100) to emit light in the main direction (X) in front of the illumination device (10);
- a motion device (300) configured to simultaneously move the at least one primary light module (100) around the rotation axis (RA) and the shield cover (200) with respect to each other between:
- non-illuminating positions (P1a, P2a) of the at least one primary light module (100), wherein the shield cover (200) is—seen in the main direction (X)—in front of the at least one primary light module (100) blocking the light path of the at least one primary light module (100) in order to prevent the at least one primary light module (100) to emit light in front of the illumination device (10), and
- illuminating positions (P3a, P4a) of the at least one primary light module (100), wherein the shield cover (200) is moved away from the light path of the at least one primary light module (100) to unblock the light path of the at least one primary light module (100) in the main direction (X) in order to allow the at least one primary light module (100) to emit light in front of the illumination device (10);
- and
- a frame (400), which is stationary in relation to the movements of the at least one primary light module (100) and the shield cover (200), wherein the motion device (300) is mounted on the frame (400),
- wherein in each illuminating position (P3a, 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) to allow a headlamp levelling for a vehicle headlamp,
- wherein the illumination device (10, 20) comprises a front cover (60) having a translucent section (61), and wherein the front cover (60) is arranged downstream of the at least one primary light module (100) in the main direction (X), wherein in the illuminating positions (P3a, P4a) the at least one light module (100) emits light through the translucent section (61) in front of the illumination device (10), and
- wherein in the non-illuminating positions (P1a, P1b, P2a) the shield cover (200) is also blocking the translucent section (61) of the front cover (60) in order to prevent the at least one primary light module (100) to emit light in front of the illumination device (10, 20), wherein in the illuminating positions (P3a, P4a, P3b) the shield cover (200) is moved away from the translucent section (61) of the front cover (60).
