Illumination device for a vehicle headlamp

Abstract

Illumination device () for a motor vehicle headlamp for generating a low beam, wherein a vertical extension of the low beam extends along a VV-line from at least 0° down to at least −10° on the VV-line, said illumination device () comprises: —an optic body () comprising a common light input section (), a light output section () and a shell surface () limiting the optic body (), —a projection lens system () configured to project the light-rays in front of the illumination device (), wherein the projection lens system () in combination with the optic body () are configured to generate the low beam illuminated by the projection lens system (), wherein the optic body () comprises a first set of optically operative surfaces for guiding light-rays along a first light-ray path (LR), wherein the first set of operative surfaces comprises a first and second light deflection surface (), and a first light exit surface (), wherein the first and second light deflection surfaces () are arranged on the shell surface (), and wherein the first light exit surface () is arranged on the light output section (), wherein light rays following the first light-ray path (LR) are incident on the first deflection surface () and are deflected to the second deflection surface (), and wherein light-rays incident on the second deflection surface () are deflected to the first light exit surface (), and wherein light-rays emitted by the first light exit surface () contribute to generate a first part of the low beam, and wherein the optic body () comprises a second set of optically operative surfaces for guiding light-rays along a second and a third light-ray path (LR, LR), wherein the second set of optically operative surfaces comprises a third deflection surface () and a second light exit surface (), wherein the third deflection surface () is arranged on the shell surface () and the second light exit surface () is arranged on the light output section () separate from the first light exit surface (), wherein light-rays following the second light-ray path (LR) are incident on the third deflection surface () and are deflected to the second light exit surface () for coupling out of the optic body (), and wherein light rays following the third light-ray path (LR) are incident on the second light exit surface () directly from the common light input section (), wherein light-rays emitted by the second light exit surface () contribute to generate a second part of the low beam.
