ABSTRACT:
Coated articles having optically useful reflective properties suitable for manufacture of components of lighting fixtures and the like including parabolic louvers utilized as primary elements of fluorescent parabolic troffer lighting fixtures, the invention provides light sheets formed of said coated articles and used in the manufacture of lighting fixtures, the reflective lighting components formed from said light sheets and the coated articles including the coatings utilized for coating optically reflective substrates according to the invention. The coated articles are formed of reflective substrates and particularly polished metal substrates having reflectance values within a predetermined useful range, the substrates being coated preferably with a thin polymeric coating wherein the base polymer is polyester, polycarbonate, epoxy, acrylic, acrylate, etc. The coating particularly provides mechanical properties to the article including wear resistance and environmental protection and further including light transmission and surface reflectance properties as well as enhanced appearance. Substrate materials include aluminum and aluminum alloys as well as steels, plated steels and metalized substrates. The invention further includes novel uses of polymeric coating compositions which are applied to the substrates according to the invention for production of the coated articles of the invention.
