The present invention relates to a light module (10) for an illumination device, in particular for a headlight (1), of a motor vehicle. The light module (10) comprises at least one light source (18) for emitting light beams, at least one primary optical unit (20) for concentrating the emitted light beams, a diaphragm arrangement (22) in the beam path of the concentrated light beams, and at least one secondary optical unit (30) for imaging the light beams that have traveled past the diaphragm arrangement (22) onto a roadway in front of the motor vehicle in order to generate a desired light distribution. There is formed in the diaphragm arrangement (22) at least one opening (26) and/or cutout to which is assigned an optically active element (28), which deflects or attenuates at least a portion of the light beams passing through the opening (26) and/or cutout.
The invention relates to a projection module for a headlight. The module generates light distributions with light sources switchable independently. In order to generate a first distribution, light from a first group is coupled into an optical element in the beam path. The optical element has a reflecting underside having a contour corresponding to the bright-dark boundary. The light coupled out from the optical element is projected by a lens for generating the first distribution. A further light group is additionally activated in order to generate a second distribution. The light emitted by this group illuminates a region of the light distribution above the bright-dark boundary. Part of the light from this group is coupled into the optical element, mixes there with the light from the first group and is then coupled out together to generate an unsharp bright-dark boundary.
