The motion device is configured to simultaneously perform motion of the primary light module around a rotation axis and relative motion of the primary light module and the shield cover. As shown, the lighting device is in one non-illuminating position of the primary light module, where the shield cover is located in front of the primary light module. [Diagram 2] 2 shows the lighting device of FIG. 1 in a further non-illuminating position of the main light module, the angular position of which is different from that in FIG. [Diagram 3] 1 and 2 in one illumination position of the main light module, the shield cover having been moved out of the light path of the main light module so that the main light module can emit light forward of the lighting device. [Figure 4] 1 to 3 in a further lighting position of the main light module. [Diagram 5] A further example of a lighting device according to the present invention. The lighting device is similar to the lighting device shown in Figures 1 to 4. The lighting device includes a secondary light module and a housing with an opaque front cover including a translucent (transparent) section. The lighting device is shown with the primary light module and the secondary light module in non-illuminating positions. [Figure 6] The lighting device of Figure 5 in one intermediate position, the main light module is covered by an opaque front cover, and the secondary light module can emit light through a translucent section of the front cover. [Figure 7] 5 and 6 in one lighting position of the main light module, the secondary light module being covered by a shield cover. EXAMPLES

[0040] 1 to 4 show an example of a lighting device 10 for a vehicle floodlight (such as a headlamp). The lighting device 10 provides floodlight levelling for the vehicle floodlight. The lighting device 10 comprises one main light module 100 configured to emit light along a light path in a main direction X to project a light distribution, preferably a light distribution for low beam and / or high beam, ahead of the lighting device 10, in particular onto the road. Note that the main light module 100 is rotatable about a rotation axis RA.

[0041] Furthermore, the lighting device 10 includes a movable shield cover 200 for shielding the main light module 100 to prevent the main light module 100 from emitting light forward of the lighting device 10 in the main direction X.

[0042] Furthermore, the lighting device 10 includes a movement device 300 for simultaneously performing movement of the main light module 100 around the rotation axis RA and (relative) movement of the main light module 100 and the shield cover 200 relative to each other between the non-illuminating positions P1a, P2a and the illuminated positions P3a, P4a.

[0043] In the non-illuminating positions P1a, P2a of the main light module 100, the shield cover 200 is in front of the main light module 100 - as viewed in the main direction X - and blocks (interrupts) the light path of the main light module 100 to prevent the main light module 100 from emitting light forward of the lighting device 10.

[0044] 1 and 2 both show examples of the main light module 100 in non-illuminated positions P1a, P2a.

[0045] At the lighting positions P3a, P4a of the main light module 100, the shield cover 200 is moved out of the light path of the main light module 100 so as to unblock the light path of the main light module 100 in the main direction X to enable the main light module 100 to emit light forward of the lighting device 10.

[0046] Figures 3 and 4 both show example illumination positions P3a, P4a of the primary light module 100. The primary light module 100 is at different defined angular positions around the rotation axis RA.

[0047] The movement device 300 includes a link mechanism 500 configured to link the primary light module 100 and the shield cover 200 such that driving the link mechanism 500 causes simultaneous movement of the primary light module 100 and the shield cover 200.

[0049] In each lighting position P3a, P4a the at least one primary light module 100 is at a defined angular position within a predefined operating angular range around the rotation axis RA in order to project a light distribution at different angular positions ahead of the lighting device 10 to enable floodlight levelling for automotive floodlights. The operating angular range corresponds to an angular range of 0° to -20° along the VV line (vertical line) on the measuring screen.

[0050] The shield cover 200 maintains its spatial orientation (posture) while transitioning between the non-illuminated positions P1a, P2a and the illuminated positions P3a, P4a. The shield cover 200 is movable in a substantially vertical direction—as viewed when the illuminated position 10 is properly installed (mounted) in the automobile.

[0051] Furthermore, the lighting device 10 includes a housing for accommodating the main light module 100. The housing includes an opaque front cover 60 having a translucent section 61, the front cover 60 being arranged downstream of the main light module in the main direction X, such that at the lighting positions P3a, P4a the main light module 100 emits light forward of the lighting positions 10 via the translucent section 61.

[0052] In the non-illuminating positions P1a, P2a, the shielding cover 200 also blocks the light-transmitting section 61 of the front cover 60 to prevent the main light module 100 from emitting light forward of the lighting device 10. In the illuminated positions P3a, P4a, the shielding cover 200 is moved out of contact with the light-transmitting section 61 of the front cover 60.

[0053] 5-7 show another example of a lighting device 20 for an automobile floodlight. The lighting device 20 provides floodlight leveling for an automobile floodlight. The lighting device 20 includes a main light module 100 configured to emit light along a light path in a main direction X to project a light distribution, preferably a light distribution for low beam and / or high beam, ahead of the lighting device 20, in particular onto a road. Note that the main light module 100 is rotatable about a rotation axis RA.

[0054] The lighting device 20 comprises a housing for accommodating a main light module 100. The housing comprises an opaque front cover 60 with a light-transmitting section 61, the front cover 60 being arranged downstream of the main light module 100 in the main direction X.

[0055] Furthermore, the lighting device 20 includes a movable shield cover 200 for shielding the light-transmitting section 61 of the front cover 60 to prevent the at least one main light module 100 from emitting light forward of the lighting device 20 in the main direction X.

[0056] Furthermore, the lighting device 20 includes a secondary light module 700 configured to emit light along a light path to project a light distribution ahead of the lighting device 20. The secondary light module 700 is rotatable about a rotation axis RA. The secondary light module 700 is configured to emit a light distribution ahead of the lighting device 20 that is different from the light distribution of the at least one primary light module 100, preferably the light distribution of the secondary light module 700 is a position light, a daytime running light, a sign light or a turn indicator.

[0057] The lighting device 20 further includes a movement device 300 for simultaneously performing movement of the main light module 100 and the secondary light module 700 around the rotation axis RA and (relative) movement of the main light module 100, the secondary light module 700 and the shield cover 200 relative to each other between the non-illuminating position P1b, the intermediate position P2b and the illuminated position P3b of the main light module 100.

[0058] In the non-illuminating position P1b, the primary light module 100 and the secondary light module 700 are covered by the front cover 60 such that the light paths of the primary light module 100 and the secondary light module 700 are blocked, and the shield cover 200 blocks the light-transmitting sections of the front cover 60 to prevent the primary light module 100 and the secondary light module 700 from emitting light forward of the lighting device 20. Figure 5 shows an example of such a non-illuminating position P1b of the primary light module 100 and the secondary light module 700.

[0059] In the intermediate position P2b, the primary light module 100 is covered by the opaque front cover 60 such that the light path of the primary light module 100 is blocked, and the shield cover 200 is moved out of the translucent section 61 of the front cover 60 such that the secondary light module 700 can emit light in the primary direction X through the translucent section 61 of the front cover 60 towards the front of the lighting device 20. Figure 6 shows an example of such an intermediate position P2b.

[0060] In the illumination position P3b of the primary light module 100, the shield cover 200 is moved out of the translucent section 61 of the front cover 60 to allow the primary light module 100 to emit light in the primary direction X through the translucent section 61 of the front cover 60 toward the front of the lighting device 20, the primary light module 100 is not blocked by the front cover 60, and the shield cover 200 or the front cover 60 blocks the light path of the secondary light module 700 to prevent the secondary light module 700 from emitting light in the primary direction X through the translucent section 61 of the front cover 60 toward the front of the lighting device 20. Figure 7 shows an example of the illumination position P3b of the primary light module 100, where the primary light module 100 is at a defined angular position around the rotation axis RA.

[0061] The motion device 300 includes a link mechanism 500 configured to link the primary light module 100, the secondary light module 700, and the shield cover 200 such that driving the link mechanism 500 causes simultaneous motion of the primary light module 100, the secondary light module 700, and the shield cover 200. Furthermore, the motion device 300 includes a leveling motor 310 configured to simultaneously drive (actuate) the motion of the primary light module 100, the secondary light module 700, and the shield cover 200.

[0062] Furthermore, the lighting position 20 includes a frame 400 which is stationary with respect to the movement of the primary light module 100, the secondary light module and the shield cover 200, and the movement device 300 is attached to the frame 400.

[0063] At each lighting position P3b, the main light module 100 is at a defined angular position of a predefined operating angle range around the rotation axis RA in order to project a light distribution at different angular positions in front of the lighting device 20 to enable floodlight levelling for automotive floodlights.
