Abstract

A lighting device, a method of manufacturing a lighting device and a support are described. A support includes a layered structure of alternating conductors and insulating layers. The layered structure includes a mounting section and a body section adjacent the mounting section. The mounting section includes at least one mounting face that has an arrangement direction and at least three alternating contact sections along the arrangement direction. Each contact section is electrically coupled to one of the conductors and separated from a neighboring one of the contact sections by one of the insulating layers. The body section has a width that protrudes sidewards from the at least one mounting face and a length that extends substantially parallel to the arrangement direction.

First claim

What is claimed is:

1. A support for light-emitting elements, the support comprising:
a layered structure of alternating conductors and insulating layers, the layered structure comprising a mounting section and a body section adjacent the mounting section,
the mounting section comprising:
at least one mounting face that has an arrangement direction, and
at least three alternating contact sections along the arrangement direction, each contact section electrically coupled to one of the conductors and separated from a neighboring one of the contact sections by one of the insulating layers, and

the body section having a width that protrudes sidewards from the at least one mounting face and a length that extends substantially parallel to the arrangement direction.

2. The support according to claim 1 ,
wherein the width of the body section increases with increasing distance from the mounting section.

3. The support according to claim 2 , wherein the body section has a triangular cross section with the mounting section disposed on an edge of the triangular cross section.

4. The support according to claim 3 ,
wherein the triangular cross section has an opening angle of 0° to 90°.

5. The support according to claim 1 ,
wherein the conductors comprise metallic sheet material.

6. The support according to claim 5 ,
wherein the metallic sheet material comprises a main face and side faces, and each of the contact sections is respectively at least partially formed by one of the side faces of the metallic sheet material.

7. The support according to claim 1 ,
wherein, within the mounting section, the layered structure of conductors and insulating layers extends substantially perpendicular to the arrangement direction of the at least one mounting face.

8. The support according to claim 1 ,
wherein the mounting section comprises at least two mounting faces arranged adjacent to each other.

9. The support according to claim 1 , wherein the mounting section comprises at least two mounting faces at an angle to each other.

10. The support according to claim 1 , wherein the mounting section comprises at least two mounting faces substantially parallel to each other.

11. The support according to claim 1 ,
wherein the mounting section comprises three mounting faces, one of the three mounting faces disposed between the other two of the three mounting faces with an enclosing angle of 45° to 135°.

12. The support according to claim 1 , wherein the mounting section comprises three mounting faces, one of the three mounting faces disposed substantially perpendicular to the other two of the three mounting faces.

13. A lighting device comprising:
a layered structure of alternating conductors and insulating layers, the layered structure comprising a mounting section and a body section adjacent the mounting section,
the mounting section comprising:
at least one mounting face that has an arrangement direction, and
at least three alternating contact sections along the arrangement direction, each contact section electrically coupled to one of the conductors and separated from a neighboring one of the contact sections by one of the insulating layers, and

the body section having a width that protrudes sidewards from the at least one mounting face and a length that extends substantially parallel to the arrangement direction; and
at least one light-emitting element mounted along the arrangement direction of the at least one mounting face and electrically coupled to at the least two of the at least three contact sections.

14. The lighting device according to claim 13 , further comprising:
a socket connected to the body section and configured for electrical coupling to a power source.
