Abstract
A stackable louver assembly for light fixtures which can be made of a high strength polycarbonate light transmitting plastic material and which has a sleeve and louver flange molded in one piece so that the sleeve will not be lost or discarded at the job site. The louver assembly becomes self-enclosed. The louver assemblies are made so they can be stacked one on top of the other and fastened with tie rods at desired locations. The sleeve that supports the louver flange is made with a surface that is generally parallel to the longitudinal axis of the assembly, and can be provided with v-type grooves to provide refraction of the light emanating from an interior lamp. The grooves can be molded into the plastic with no increase in cost, and will reduce glare and improve overall performance of the fixture. Likewise, the louver flanges may have surfaces that are provided with refraction grooves, as well.
