ABSTRACT:
A reflector includes multiple segments that can be interconnected by a flexible extrusion and connected to a top collar to form a reflective shell around a light source. The segments are corrugated for increased strength, the corrugations forming elongate facets characterized by reflective surfaces that reflect light laterally beside the light source as well as downwardly from the light source to minimize light reflected back toward the light source and maximize the service life of the light source. The corrugations add strength and stability to the segments permitting the sheet thickness, overall reflector weight, and cost to be minimized. The segments are preferably formed from a stamped aluminum sheet of about 0.020 inch thickness, and can be pre-or-post anodized to form the reflective surfaces, the pre-anodized surfaces being protected by a polycoat during stamping. Differently shaped segments can be arranged as desired to achieve a desired pattern of reflected light, and differently shaped top collars can be used to adapt the reflector for use on different light sources. The reflector can be shipped in a knocked-down state to minimize space required for shipping or storage, and assembled or repaired on site.
