The invention relates to a light module () for a motor vehicle headlight (), for generating an adaptive light distribution. The light module () comprises a light source () for emitting light, a primary optical element () for focusing the emitted light, and a diaphragm arrangement (') for implementing a variable effective upper edge (&#x2032;), which can be introduced into a beam path of the emitted and/or focused light. To provide a simple and cost effective way to improve the visibility of the driver of the motor vehicle (), but not result in a glare to other road users, it is proposed that the diaphragm arrangement (&#x2032;) is designed to implement an effective upper edge (&#x2032;) is formed, which brings about the generation of a lower beam light distribution () with substantially horizontal light-dark boundary () and with an illuminated region () formed at a specific horizontal position above the light-dark boundary (), which region is delimited on the right-hand side and on the left-hand side by light-dark boundaries and has an extent in the horizontal and vertical directions of in each case a few angular degrees on a measuring screen arranged at a distance in front of the headlamp (). By pivoting the light module () horizontally the light can be directed precisely, the illuminated region () can be moved in the horizontal direction onto detected objects in a front of the vehicle ().

Light module for a motor vehicle headlamp

The present invention relates to a light module () for an illumination device, in particular for a headlight (), of a motor vehicle. The light module () comprises at least one light source () for emitting light beams, at least one primary optical unit () for concentrating the emitted light beams, a diaphragm arrangement () in the beam path of the concentrated light beams, and at least one secondary optical unit () for imaging the light beams that have traveled past the diaphragm arrangement () onto a roadway in front of the motor vehicle in order to generate a desired light distribution. There is formed in the diaphragm arrangement () at least one opening () and/or cutout to which is assigned an optically active element (), which deflects or attenuates at least a portion of the light beams passing through the opening () and/or cutout.
