ABSTRACT:
A polycarbonate orientable refractor for a luminaire comprises a mounting ring which has a collar portion fitting a neck portion of the refractor with matching diameters. A diametric interference is provided between a groove in one part and a mating ridge in the other part to an extent allowing a snap fit. Shallow interfering ribs and valleys in the mating surfaces controllably lock the parts together while allowing angular indexing for orienting the light distribution pattern of the refractor.
