Projection Module for a Motor Vehicle Headlamp
A projection module (10) for a motor vehicle headlamp, comprising a first light source (110) and a second light source (120), a beam stop (200), which is horizontally arranged, and which comprises an optically relevant stop edge (210) for creating an asymmetric light-dark boundary, wherein the first light source (110) is arranged on a top side of the beam stop (200) and, in combination with the stop edge (210), contributes to the creation of a low beam distribution, and wherein the second light source (120) is arranged on a bottom side of the beam stop (200) and contributes to the creation of a high beam distribution, and a projection lens (300), wherein the projection module (10) comprises an auxiliary stop (400), which is vertically arranged below the beam stop (200), and which has a vertically extending first optically relevant stop edge (410), which is configured to partially shade light from the second light source (120), so that a partial high beam distribution can be created, and wherein the auxiliary stop (400) has a fastening section (430), wherein, in the vertical extension in the direction of the beam stop (200), the first stop edge (410) has an end (411), which end (411) has a distance from the beam stop (200), and wherein the auxiliary stop (400) has a second optically relevant stop edge (420), which, starting at the end (411) of the first stop edge (410), extends all the way to the fastening section (430), wherein, in a projection onto the beam stop (200), the second stop edge (420) defines a gap, which gap, in combination with the second light source (120), is configured to create a segment (500) in the partial high beam distribution.

VEHICLE HEADLAMP
A vehicle headlamp includes a shade that shields a part of light emitted from a light source. A predetermined end edge of the shade serves as a cut line forming portion that forms a cut line of a light distribution pattern and the shade is provided with a dimming portion positioned behind the cut line forming portion. The cut line forming portion and the dimming portion form a low-brightness portion having a lower brightness than that of other portions in a part of the light distribution pattern. A portion of the shade including the cut line forming portion is provided as a flat plate-shaped functional surface portion and at least the functional surface portion is tilted backward and downward.

Lighting device
A lighting device includes: a light source having a light-emitting surface; a reflector having a reflective surface configured to reflect light emitted from the light source; and a lens on which light reflected by the reflective surface is incident. The reflective surface is composed of a portion of a spheroidal surface that includes a first focal point located on the light-emitting surface and a second focal point located between the reflective surface and the lens. The reflective surface intersects a major axis of the spheroidal surface. A value obtained by dividing a first distance, which is a distance between the first focal point and the second focal point, by a second distance, which is a distance between the first focal point and an intersection point of the reflective surface and the major axis, is 7 or greater.
