Abstract
An illumination device, for vehicle headlamps, includes a light source, a shutter device, and a projection lens. The shutter device has a first shutter body with a first shutter plane including a first shutter edge, and a second shutter body with a second shutter plane including a second shutter edge. The first and second shutter bodies are arranged such that their shutter edges build a common shutter edge, which generates a cut-off line of a light distribution. The shutter device is configured to transition the first and second shutter edges between (i) aligned positions wherein the common shutter edge contributes to generate a straight cut-off line, and (ii) non-aligned positions wherein the common shutter edge contributes to generate a cut-off line deviating from a straight cut-off line. The transition is performed by rotation of the first and/or second shutter body about a common rotation axis by a rotation device.
