Abstract

Luminaire for indoor industrial use has an optical assembly having a diameter substantially greater than its height and adapted to be mounted at a relatively low height above the floor. The optical assembly comprises a reflector with fluted concave upper portion and an outwardly flaring lower skirt portion to which a large diameter dish-shaped refractor is secured. The refractor has an annular side wall formed with horizontal rows of prisms which depress part of the incident light and reflect the remaining light rays upwardly toward the ceiling. The bottom panel of the refractor is formed with radial light dispersing flutes.
