Projection module for motor vehicle headlamp

Abstract

The invention relates to a projection module (10) for a motor vehicle headlamp, comprising: a first light source (110) and a second light source (120); a radiation diaphragm (200) arranged horizontally and comprising an optically associated diaphragm edge (210) for creating an asymmetric light and shade boundary, in which a first light source (110) is arranged at an upper side of the radiation diaphragm (20) and cooperates in conjunction with the diaphragm edge (210) for creating a low beam distribution, and in which a second light source (110) is arranged at a lower side of the radiation diaphragm (20) and cooperates in conjunction with the diaphragm edge (210) for creating a low beam distribution. A second light source (120) arranged at an underside of the radiant baffle (200) and cooperating for generating a high beam distribution; the projection module (10) comprises an additional diaphragm (400), which is arranged vertically below the radiation diaphragm (200) and has a vertically extending first optically associated diaphragm edge (410), which is arranged to partially shield light from the second light source (120) so that a partial high beam distribution can be produced, and wherein the additional diaphragm (400) has a fixed section (430), which is arranged vertically below the radiation diaphragm (200) and has a first optically associated diaphragm edge (430) which extends vertically and which is arranged to partially shield light from the second light source (120) so that a partial high beam distribution can be produced. The first diaphragm edge (410) has an end (411) in a vertical extension in the direction of the radiation diaphragm (200), which end (411) is at a distance from the radiation diaphragm (200), and wherein the additional diaphragm (400) has a second optically relevant diaphragm edge (420), which extends from the end (411) of the first diaphragm edge (410) to a fastening section (430), the second diaphragm edge (420) defines a gap in the projection onto the radiation diaphragm (200), which gap is designed in conjunction with the second light source (120) to produce a section (500) in a partial high beam distribution.

Description

technical field [0001] The invention relates to a projection module for a motor vehicle headlight, comprising the following: [0002] - a first light source and a second light source, [0003] - a radiating baffle, which is arranged to be arranged horizontally when the projection module is used according to the regulations in an installed motor vehicle headlamp, and which comprises an optically relevant baffle edge for producing an asymmetric light-dark boundary, wherein the first light source is arranged at the upper side of the radiation baffle and cooperates with the optically relevant baffle edges of the radiation baffle for generating a low beam distribution, and wherein the second light source is arranged at the lower side of the radiation baffle and cooperates for produces a high beam distribution, [0004] - at least one projection lens with an optical axis and a focal plane for projecting the light distribution in front of the projection module in the main radiation...

However, there is no difference in the case of legal requirements, since a separate fulfillment of the headlights is required, i.e. certain points and lines of the legal assessment must also be met at places where no light can reach due to the isolation of the installed additional partitions
