ABSTRACT:
A high beam, low brightness luminaire including an inverted dish-shaped housing of a frustoconical configuration terminating in an annular peripheral edge at its larger end. A generally frustoconical translucent refractor is secured to the annular peripheral edge of the housing at its larger end and an inwardly directed annular flange on the smaller end provides the sole support for a bowl-shaped, transparent, prismatic refractor which hangs therefrom. The normally open bottom of the bowl-shaped refractor may be closed off by a disc-shaped translucent diffusing refractor to complete the sealed optical system.
