An illumination apparatus having a light source and a refractive element, said refractive element having surfaces for incident the light emerging from the light, said incident surface characterized by continuous prisms extending below the light source and having active surfaces for redirecting the rays of light emitted by the light source longitudinally and transversely to the active surfaces, in lateral planes with a relatively narrow angular range, on opposite sides to, and away from, a vertical plane through the light source, in order to direct light to a work surface with such lateral and longitudinal angles in relation thereto, so as to avoid reflection from said working surface to the eye of a person working on said surface of work.
