Abstract

The invention describes an integral lighting assembly (1A, 1B, 1C, 1D, 1E) comprising an optical arrangement (2, 3); a first light source (S1) for generating a first beam (L1) of light; a first collimator (C1) for directing the first beam (L1) at the optical arrangement (2, 3); a second light source (S2) for generating a second beam (L2) of light; and a second collimator (C2) for directing the second beam (L2) at the optical arrangement (2, 3), wherein the optical arrangement (2, 3) is realized to manipulate the first and second light beams (L1, L2) to give a first exit beam (BLO) and a second exit beam (BRI) such that the first exit beam (BLO) and the second exit beam (BRI) are partially combined in an overlap region (44) on a projection plane (4) located at a predefined distance from the integral lighting assembly (1A, 1B, 1C, 1D, 1E). The invention further describes an automotive headlamp arrangement (12) comprising such an integral lighting assembly (1A, 1B, 1C, 1D, 1E).
