Abstract: The invention relates to a lighting arrangement, in particular a lighting arrangement which may be used in a headlamp of a vehicle. A beam shaping arrangement comprises a light input portion for receiving light emitted from a light source and a light output portion for emitting a shaped beam. The light output portion is spaced from the light input portion in a forward direction. In order to achieve a desired illumination beam pattern suited for a vehicle headlamp the beam shaping arrangement is disposed to divide light from the light input portion into at least a first and a second beam portion separated in height direction. The first and second beam portions are led to converge in the height direction towards the light output portion. At the light output portion, the second beam portion is directed at a peripheral portion arranged laterally further outward relative to the first beam portion.
