Illumination device for vehicle headlamps

An illumination device (10) for single-track vehicle headlamps, wherein the illumination device (10) is configured to form a light distribution with a cut-off line, the illumination device comprising:

• at least one light source (20) configured to emit light in a main direction (X) for forming the light distribution;
• a shutter device (100) arranged downstream of the at least one light source (20) along the main direction (X), wherein the shutter device (100) is configured to generate the cut-off line in the light distribution;
• a projection lens (200) for projecting the generated light distribution of the at least one light source (20) in conjunction with the shutter device (100) in front of the illumination device (10), wherein the projection lens (200) comprises an optical axis (A);
• and
• a holder (300) configured to hold the shutter device (100) and the projection lens (200),
• wherein the shutter device (100) is formed of:
• a first shutter body (110) with a first shutter plane (110a) comprising a first shutter edge (110b), and
• a second shutter body (120) with a second shutter plane (120a) comprising a second shutter edge (120b),
• wherein the first and second shutter body (110, 120) are arranged to one another such that the first and second shutter edge (110b, 120b) together build a common shutter edge (150), which generates the cut-off line in the light distribution,
• wherein the shutter device (100) is configured to transition between
• aligned positions of the first and second shutter edge (110b, 120b), wherein the common shutter edge (150) contributes to generate a straight cut-off line, and
• non-aligned positions of the first and second shutter edge (110b, 120b), wherein the first and second shutter edge (110b, 120b) are inclined with respect to each other, so that the common shutter edge (150) contributes to generate a cut-off line deviating from a straight cut-off line, and
• wherein the transition between the positions is performed by rotation of the first and/or second shutter body (110, 120) about a common rotation axis (R) by means of a rotation device (400).
