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.

Claims

1. A reflector for an ornamental luminaire comprising:

a member formed of a metal material, said metal member having a predetermined thickness and being perforated with spaced apart apertures of a selected diameter and a selected density;

said metal member having a predefined reflector shape, said spaced apart apertures and said predefined reflector shape arranged for providing control of both an upper illumination distribution and a lower illumination distribution; and

wherein said metal member perforated with spaced apart apertures of approximately 2.2 mm diameter on approximately 6 mm center to center location.

2. A reflector for an ornamental luminaire comprising:

a member formed of a metal material, said metal member having a predetermined thickness and being perforated with spaced apart apertures of a selected diameter and a selected density;

said metal member having a predefined reflector shape, said spaced apart apertures and said predefined reflector shade arranged for providing control of both an upper illumination distribution and a lower illumination distribution; and

wherein said sloped, vertically extending, sidewall is fluted and includes elongated apertures.

3. A reflector for an ornamental luminaire as recited in claim 2 wherein said reflector metal member includes a plurality of positioning tab portions arranged for press-fit engagement within the ornamental luminaire.

4. A reflector for an ornamental luminaire as recited in claim 3 wherein the ornamental luminaire includes a lower ornamental luminaire body having an interior surface and wherein said positioning tab portions have a predetermined size to deform into an outwarding extending ledge on the interior surface of the lower ornamental luminaire body.

5. A reflector for an ornamental luminaire as recited in claim 2 wherein a hydroforming technique is used to form the metal member into the predefined reflector shape.

6. A reflector for an ornamental luminaire as recited in claim 5 wherein a stamping process is used to trim the metal member to a desired diameter and to provide a plurality of positioning tab portions in a precompression state.

7. A reflector for an ornamental luminaire comprising:

a member formed of a metal material, said metal member having a predetermined thickness and being perforated with spaced apart apertures of a selected diameter and a selected density;

said metal member having a predefined reflector shape, said spaced apart apertures and said predefined reflector shape arranged for providing control of both an upper illumination distribution and a lower illumination distribution; and

wherein said metal member predetermined thickness is approximately 1.25 mm.

8. A reflector for an ornamental luminaire as recited in claim 7 wherein said metal member has substantially uniformly spaced apart apertures of said selected diameter and said selected density.

9. A reflector for an ornamental luminaire as recited in claim 7 wherein said predefined reflector shape includes a generally circular outer rim portion, and a sloped, vertically extending, sidewall.

10. A reflector for an ornamental luminaire as recited in claim 9 wherein said predefined reflector shape includes a generally flat upper portion with a centrally disposed upper peaked portion, said upper peaked portion located above a lamp in the ornamental luminaire.

11. A reflector for an ornamental luminaire as recited in claim 7 wherein said metal member material is an aluminum alloy.

12. A reflector for an ornamental luminaire as recited in claim 11 wherein said metal member material is a selected one of aluminum alloys, 3002, 3003 and 1100-0.
