Abstract
A new and improved luminaire combination is disclosed having a novel lens structure formed with a generally horizontal first lens surface and a generally vertical second lens surface with a generally horizontal flange formed on the second lens surface. The first lens surface is designed to refract a beam of light downwardly and outwardly in a predetermined pattern to form a beam having a cross section approximating the predetermined pattern at a predetermined distance below the lens. The second lens surface is designed to diffuse a beam of light outwardly in a direction perpendicular to the second lens surface.
