    摘要: A louver/lens assembly for placement in the light-emitting opening of a fluorescent light luminaire has a louver assembly mounted in the light-emitting opening of the luminaire. On top of the louver assembly, and between it and the fluorescent tubes, a prism lens, typically formed from a sheet of extruded transparent acrylic material, is placed. The lens sheet is flat on the surface facing the fluorescent tubes in the fixture, and has parallel longitudinal prisms formed in the surface overlying the louver assembly. The prisms are selected to direct light rays passing through the lens assembly downwardly through the openings between the longitudinal and transverse louvers of the louver assembly.
