ABSTRACT:
A light fixture has an elongated housing having a floor and side walls defining a transversely open and longitudinally extending outlet and a light source extending longitudinally in the housing. A U-section asymmetrical primary reflector extending longitudinally in the housing between the source and the floor is oriented to reflect light from the source out through the outlet. Two longitudinally extending generally triangular-section secondary reflectors extend longitudinally spacedly adjacent one another between the source and the outlet. The secondary reflectors have outwardly concave first sides directed toward each other, concave second sides directed away from each other, and outwardly concave third sides directed toward the source. Thus light from the source is directed back toward the source and the first reflector by the third sides, is scattered outward through the outlet by the second sides, and is directed outward through the outlet by the first sides.
