Abstract

A flexible lighting system and method of making same is disclosed. The flexible lighting system includes a flexible translucent rod and an attachment flange. Preferably, the outer casing and the attachment flange are integrally formed to facilitate installation. The flexible translucent rod includes an outer casing and a lighting core. The lighting core is disposed within an axial aperture defined by the outer casing and contains a series of lighting elements. In the preferred embodiment, a texture, such as axial grooves, is applied to a surface of the flexible translucent rod. This texture may be applied to the outer surface of the lighting core or the inner surface of the outer casing to diffuse the light emitted by the discrete lighting elements, thereby providing an appearance similar to a solid bar of light.

Claims

1. A flexible lighting system comprising:

a plurality of sets of electrically interconnected lighting elements, said sets being electrically coupled to one another;

a flexible translucent rod containing said plurality of sets of electrically interconnected lighting elements, said rod having a circumference and an axis; and

an attachment flange axially connected to said flexible translucent rod, said attachment flange being formed integrally with said flexible translucent rod and facilitating installation of said flexible translucent rod,

whereby said flexible translucent rod and said integrally formed attachment flange can be cut in regions intermediate of respective ones of the sets of electrically interconnected lighting elements without affecting the electrical interconnection within any such sets of electrically interconnected lighting elements.

2. The flexible lighting system of claim 1, wherein said flexible translucent rod forms a generally cylindrical aperture for holding an inner lighting core, said inner lighting core having a textured outer surface for diffusing light emitted from the lighting elements.

3. The flexible lighting system of claim 2, wherein the textured outer surface comprises axial grooves.

4. The flexible lighting system of claim 1, wherein said flexible translucent rod forms a generally cylindrical aperture for holding an inner lighting core, said aperture being formed by an inner surface of said flexible translucent rod, the inner surface being textured for diffusing light emitted from the lighting elements.

5. The flexible lighting system of claim 4, wherein the textured inner surface comprises axial grooves.

6. The flexible lighting system of claim 1 further comprising:

a power connector for providing electrical power to said system; and

a power receptor for receiving electrical power from said power connector, said power receptor including a compression fitting positioned co-axially with said translucent rod and disposed at an end of said translucent rod;

a compression collar disposed around said translucent rod, and a conductive insert for mating said power receptor with said power connector, the conductive insert disposed between and retained by the compression fitting and the compression collar.

7. A method of making a flexible lighting system comprising the steps of:

extruding an inner lighting core, said inner lighting core formed of flexible translucent material and containing a plurality of lighting elements; and

extruding an outer casing for said inner lighting core, said outer casing having inner and outer surfaces and including an attachment arrangement integrally formed therewith.

8. The method of claim 7 further comprising applying a texture to the outer surface of the inner lighting core to diffuse light emitted by the plurality of lighting elements.

9. The method of claim 8, wherein the applied texture of the outer surface of the inner lighting core comprises axial grooves.

10. The method of claim 7, further comprising applying a texture to the inner surface of the outer casing to diffuse light emitted by the plurality of lighting elements.

11. The method of claim 10, wherein the texture applied to the inner surface of the outer casing comprises axial grooves.
