Abstract

Abstract of the Disclosure

An improved formed lighting fixture having a frame, a plurality of bulbs, and a refracting layer, in which the frame is formed by gathering a plurality of rods and profiled in a specific contour, the bulbs are installed on the frame to serve as lighting ornaments, and the rod frame is coated with a refracting layer of a transparent material. A formed lighting fixture so constructed can offer a dazzling effect to thereby reduce bulb amount and facilitate production.

Claims

1. A decorative lighting fixture comprising a frame having structural elements adapted to create a desired shape, a plurality of bulbs spaced about and coupled to the frame, and light-refracting material coupled to the frame to form a refractive layer over the frame such that light exiting the fixture is refracted by the coating.

2. The lighting fixture of claim 1 wherein the structural elements are rod sections.

3. The lighting fixture of claim 1 wherein the structural elements are a plurality of rods molded and coupled together to create the desired shape.

4. The lighting fixture of claim 1 wherein the bulbs are attached directly to the frame.

5. The lighting fixture of claim 1 wherein the bulbs are positioned within the frame.

6. The lighting fixture of claim 1 wherein the light-refracting material comprises plastic.

7. The lighting fixture of claim 1 wherein the light-refracting material is tinted to add color to the lighting fixture.

8. The lighting fixture of claim 1 wherein the light-refracting material is thready.

9. The lighting fixture of claim 1 wherein the refractive layer is tinted differently in different locations on the frame to create a colored pattern on the lighting fixture.

10. The lighting fixture of claim 1 wherein the light-refracting material is transparent.

11. The lighting fixture of claim 1 wherein the desired shape is an animal.

12. The lighting fixture of claim 1 wherein the desired shape is a plant.

13. The lighting fixture of claim 1 wherein the light-refracting material is in the form of at least one elongated length of material being distributed about the frame.

14. The lighting fixture of claim 1 wherein the light-refracting material does not cover the entire frame.

15. The lighting fixture of claim 1 wherein the light-refracting material is fused to the frame.

16. A method for making a lighting fixture, comprising forming a frame, coupling bulbs to the frame, and distributing a light-refracting material about the frame to form a refractive layer over the frame.

17. The method of claim 16 wherein forming the frame comprises molding a rod member.

18. The method of claim 16 wherein forming the frame comprises coupling together a plurality of rod members.

19. The method of claim 16 wherein coupling bulbs to the frame comprises attaching bulbs directly to the frame.

20. The method of claim 16 wherein distributing the light-refracting material comprises scattering the transparent material about the frame.

21. The method of claim 16 wherein distributing the light-refracting material comprises randomly distributing the transparent material about the frame.

22. The method of claim 16 wherein distributing the light-refracting material comprises threading the transparent material to the frame.

23. A lighting fixture comprising a plurality of elongated structural members coupled together to create a frame with a desired shape, a plurality of bulbs spaced about and coupled to the frame, and at least one elongated thread distributed about and coupled to the frame to form a refractive layer over the frame, the thread being adapted such that at least some of the light exiting the fixture is refracted as it passes through the thread.

24. The lighting fixture of claim 23 wherein the elongated thread is fused to the frame.

25. The lighting fixture of claim 23 wherein the elongated thread is configured in a random pattern.

26. The lighting fixture of claim 23 wherein the elongated thread does not cover the entire frame.

27. The lighting fixture of claim 23 wherein the elongated thread is configured in a scattered pattern on the frame.
