ABSTRACT:
A reflector for obtaining isolux light distribution patterns over polygonal areas is disclosed. The reflector is equipped with a plurality of circumferentially adjacent light transmissive wall sections corresponding in number to the number of corners of the polygonal light pattern. A reflective coating and vertically oriented prisms formed on the outer surface of the wall sections cooperate to reflect and laterally redirect light to provide the desired isolux polygonal light pattern.
