Abstract
A lighting fixture consisting of a downwardly opening housing having a plurality of fluorescent lamps mounted therein, a louver assembly substantially closing the open bottom of the housing and dividing its area into vertically open cells only certain of which receives light from each of the lamps, the louvers being of sufficient vertical height to restrict light passing directly through the cells to a restricted primary area of brighter illumination in the room below, and a translucent light-diffusing panel covering the cells of the louver assembly receiving light from each of the lamps. The lamps may be selected to emanate light of respectively different colors, and both the louvers and the light-diffusing panels may be of selectively different tints and colors, so as to impart a novel, decorative appearance to the louver assembly when viewed from outside of the primary lighting area.
