Abstract
In brief, the objects and advantages of the present invention are achieved by a reflector for an ornamental luminaire. The reflector includes a member formed of a metal material, the metal member having a predetermined thickness and being perforated with spaced apart apertures of a selected diameter and selected density. The metal member has a predefined reflector shape with the spaced apart apertures and the predefined reflector shape arranged to provide control of both an upper illumination distribution and a lower illumination distribution. The reflector metal member includes a plurality of positioning portions arranged for press-fit engagement within the ornamental luminaire. A hydroforming technique is used to form the metal member into the predefined reflector shape. The reflector is trimmed via a stamping process to a desired diameter and to provide the plurality of positioning portions in a precompression state. The positioning portions are sized to deform into an outwarding extending ledge on the interior surface of the lower ornamental luminaire body.
