Abstract

A lighting arrangement 10 is described with an LED element 30. A reference frame part 14 comprises a frame opening 26 bordered by frame edges 28a, 28b, 28c, 28d. The LED element 30 is arranged such that light is emitted through the frame opening 26 and is partially shielded at least at a first frame edge 28b. The reference frame part further comprises reference portions 20a, 20b, 20c, 20d to define positions relative to the frame 5 opening. A first reference portion 20a, 20b is provided on a first surface portion of the reference frame part 14 arranged parallel to a light emitting surface 38 of the LED element 30. A second reference portion 20c is arranged on a second surface portion of the reference frame part 14 arranged perpendicular to the first surface portion. A third reference portion 20d is arranged on a third surface portion of the reference frame part 14 arranged 10 perpendicular to both the first and second surface portions. An optical element 12 for shaping an illumination beam 42 from light emitted from the LED element 30 through the frame opening 26 is arranged to be in contact with the reference frame part 14 at the first, second and third reference portions 20a, 20b…
