摘要： Illumination device (1) for a motor vehicle headlamp, said illumination device (1) comprises a light source (2) for emitting a light beam with a first vertical extent (v1), an optic body (3) for guiding the light beam, an optical system (5) for projecting the light beam in front of the illumination device (1), wherein the optic body (3) comprises a first pair of optically operative surfaces (6) for guiding the light beam coupled into the optic body (3), wherein the first pair of optically operative surfaces (6) consists of a first and second light deflection surface (6a, 6b), configured to deflect the light beam while travelling through the optic body, wherein the first and second light deflection surfaces (6a, 6b) are configured in such a way, that light rays forming the light beam are essentially parallel to each other and essentially parallel to a main direction (X) after being coupled out of the optic body (3), wherein the outcoupled parallel light beam has a second vertical extent (v2) in the main vertical cross section (v), said second vertical extent (v2) is greater than the first vertical extent (v1).
