The invention relates to a motor vehicle headlamp having a shielding screen (9) for shielding incident solar radiation, wherein the shielding screen is arranged between a lighting unit (2) having at least one light source (3), and a projection optics (8). Said shielding screen has a light outlet aperture for light radiated by the light unit to the front, wherein the light emitted by the lighting unit is projected into the traffic space as a light image by means of the projection optics, and the shielding screen is located outside the focal plane of the projection optics. On the border (13) of the light outlet aperture (10) of the shielding screen (9), deflective structures (14, 15, 16, 17, 18, 19) are formed, a least in some areas, which lead to a deflection of scattered light that is emanating from the lighting unit and is undesirable in the light image.

The present disclosure provides an illumination structure and a light distributing method. The illumination structure includes a substrate, a first light emitting element, a second light emitting element, a reflection housing and a hooding board. The reflection housing has a first focal point and a second focal point. The first light emitting element is disposed on the substrate and located at the first focal point of the reflection housing. The second focal point is positioned within the hooding board. Therefore, a portion of light emitted by the first light emitting element will be reflected by the reflection housing and pass through a hollow portion of the hooding board to generate low beam light.

The left headlamp (100L) includes first light source modules (13L, 14L, and 15L) and a light guide member (16L). The first light source modules (13L, 14L, and 15L) corresponds to partial light distributing patterns (P1L, P2L, and P3L) and have light projection directions parallel to each other. The light guide member (16L) has: first incident surfaces (17L, 18L, and 19L), arranged so as to face the first light source modules (13L, 14L, and 15L) and corresponding to the first light source modules (13L, 14L, and 15L); and an emitting surface (20L), arranged so as to face the first incident surfaces (17L, 18L, and 19L) and shared by the first light source modules (13L, 14L, and 15L). The light guide member (16L) forms a light distributing pattern (PL) by deflecting light projected by the first light source modules (13L, 14L, and 15L).
