Abstract
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.
