Abstract

A lighting fitting (1) for an essentially point shaped light source (2), including a reflector (3) and a light spreading cover. According to the invention the cover includes a first outer conical surface (4) of prism film with standing prisms turned inwardly, said surface converging in a direction from the reflector, and a second, inner, conical surface (5) of prism film with standing prisms turned inwardly inside, attaching to the first conical surface and converging in the direction of the reflector, whereby the reflector is shaped as a shallow bowl and placed such with respect to the light source that essentially all light from the light source being directly reflected meet the outer cone surface.
