Lighting arrangement, which may be used e.g. in vehicle lighting, comprising - at least one LED element with a light emitting surface, - a reference frame part comprising a frame opening of rectangular shape bordered by frame edges (28a, 28b, 28c, 28d), - said LED element being arranged such that light from said light emitting surface is emitted through said frame opening and is partially shielded at least by a first frame edge, - said light emitting surface of said LED element extends at least up to said frame edges (28a, 28b, 28c, 28d) to ensure that said frame opening is entirely illuminated, such that said frame edges (28a, 28b, 28c, 28d) constitute the exact borders of an effective light emitting surface of said LED element, - said reference frame part further comprising reference portions (20a, 20b, 20c, 20d) to define positions relative to said frame opening, said reference portions including at least - a first reference portion (20a, 20b) on a first surface portion of said reference frame part arranged parallel to said light emitting surface, - a second reference portion on a second surface portion of said reference frame part arranged perpendicular to said first surface portion, - and a third reference portion on a third surface portion of said reference frame part arranged perpendicular to both said first and second surface portions, - and an optical element for shaping an illumination beam from light emitted from said LED element through said frame opening, said optical element being arranged to be in contact with said reference frame part at said first, second and third reference portions (20a, 20b, 20c, 20d) to define a position of said optical element relative to said frame opening. - at least one LED element with a light emitting surface, - a reference frame part comprising a frame opening of rectangular shape bordered by frame edges (28a, 28b, 28c, 28d), - said LED element being arranged such that light from said light emitting surface is emitted through said frame opening and is partially shielded at least by a first frame edge, - said light emitting surface of said LED element extends at least up to said frame edges (28a, 28b, 28c, 28d) to ensure that said frame opening is entirely illuminated, such that said frame edges (28a, 28b, 28c, 28d) constitute the exact borders of an effective light emitting surface of said LED element, - said reference frame part further comprising reference portions (20a, 20b, 20c, 20d) to define positions relative to said frame opening, said reference portions including at least - a first reference portion (20a, 20b) on a first surface portion of said reference frame part arranged parallel to said light emitting surface, - a second reference portion on a second surface portion of said reference frame part arranged perpendicular to said first surface portion, - and a third reference portion on a third surface portion of said reference frame part arranged perpendicular to both said first and second surface portions, - a first reference portion (20a, 20b) on a first surface portion of said reference frame part arranged parallel to said light emitting surface, - a second reference portion on a second surface portion of said reference frame part arranged perpendicular to said first surface portion, - and a third reference portion on a third surface portion of said reference frame part arranged perpendicular to both said first and second surface portions, - and an optical element for shaping an illumination beam from light emitted from said LED element through said frame opening, said optical element being arranged to be in contact with said reference frame part at said first, second and third reference portions (20a, 20b, 20c, 20d) to define a position of said optical element relative to said frame opening.
