Light module for a motor vehicle headlamp

Abstract

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 (′), 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 (′) is designed to implement an effective upper edge (′) 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 ().
