Abstract: The present invention relates to an optical arrangement (1) having an optical axis (X) and comprising a base member (70), a cup shaped reflector (10) having an inner surface (12) facing towards the optical axis, at least one solid state light source (40, 42) arranged at the optical axis on the base member, and a lens comprising a center lens portion (20) and an annular lens portion (30), and arranged in front of the at least one solid state light source in a light exit direction. The center lens portion has a dome shaped outer surface (22) and the annular lens portion has an outer surface (32) with a convex shape facing the inner surface of the reflector. The reflector and the lens are formed together as one solid piece of material.
