Claim:
1. An integral lighting assembly comprising: an optical arrangement; a first light source for generating a first beam of light; a first collimator for directing the first beam at the optical arrangement; a second light source for generating a second beam of light; and a second collimator for directing the second beam at the optical arrangement; wherein the collimators are arranged such that each collimator on one side of an optical axis of the lighting assembly directs its beam of light essentially at a region of the optical arrangement on the other side of the optical axis such that at least a portion of the first beam and at least a portion of the second beam cross the optical axis at a common point on the optical axis before arriving at the optical arrangement, wherein the optical arrangement is configured to manipulate the first beam to provide a low exit beam and to manipulate the second light beam to provide a high exit beam such that the low exit beam and the high exit beam are partially combined in an overlap region on a projection plane located at a predefined distance from the integral lighting assembly and such that a majority of the high exit beam is non-overlapping with respect to the low exit beam in the projection plane, and wherein the optical arrangement comprises a first lens and comprises, on a surface of said first lens, a plurality of linear prism elements and a plurality of linear lenses that are oriented on said surface essentially perpendicular to the linear prism elements such that one of said first beam and said second beam intersects said plurality of liner prism elements and the other of said first beam and said second beam intersects said plurality of linear lenses.
