ABSTRACT:
A louver unit for a lighting fixture assembly wherein blades extending longitudinally of the axis of an elongated lamp have reflective side surfaces curved on a relatively smaller radius and blades extending perpendicular to said elongated lamp have corresponding surfaces curved on a relatively greater radius. This produces an output of light in the longitudinal plane more nearly equal to that in the transverse plane.
