Abstract

A light source assembly, a method for producing a light source assembly, and a lamp are provided. In one example, the light source assembly comprises a substrate comprising first and second substrate portions being arranged at a tilt angle (α) to each other forming a V-shaped structure, wherein, at the tip of the V-shaped structure, the first portion comprises a first electrical terminal and the second portion comprises a second electrical terminal. The light source assembly further comprises a light source arranged to bridge a terminal gap between the first and second electrical terminals such that the light source is in electrical connection with the first and second electrical terminals.

First claim

The invention claimed is:

1. Light source assembly, comprising:
a substrate comprising first and second substrate portions being arranged at a tilt angle to each other forming a V-shaped structure, wherein, at the tip of the V-shaped structure, the first substrate portion comprises a first electrical terminal and the second substrate portion comprises a second electrical terminal; and
a light source arranged to bridge a terminal gap between the first and second electrical terminals such that the light source is in electrical connection with the first and second electrical terminals.

2. Light source assembly according to claim 1 , wherein each of the first and second substrate portions comprises a light source supporting surface, wherein the first and second electrical terminals are arranged at the respective light source supporting surface.

3. Light source assembly according to claim 1 , wherein the light source supporting surfaces are parallel.

4. Light source assembly according to claim 1 , wherein the first and second substrate portions being separated by a gap at the tip of the V-shaped structure, and wherein the light source is arranged to bridge the gap.

5. Light source assembly according to claim 1 , further comprising a mechanical support supporting the first and second substrate portions.

6. Light source assembly according to claim 5 , wherein the mechanical support is arranged at the opening of the V-shaped structure.

7. Light source assembly according to claim 1 , wherein the tilt angle (α) is acute.

8. Light source assembly according to claim 7 , wherein each of the first and second substrate portions comprises a conductor, wherein a portion of the respective conductor forms the first and second electrical terminals.

9. Light source assembly according to claim 1 , further comprising an optical element arranged at light source for controlling light emitted from the light source.

10. Light source assembly according to claim 1 , wherein the light source comprises a LED.

11. A lamp, comprising;
a bulb-shaped envelope; and
a light source assembly according to claim 1 , wherein the light source assembly is arranged within the bulb-shaped envelope.

12. Method for producing a light source assembly, the method comprising:
providing a substrate comprising a conducting path and a score line, the score line being arranged across the conducting path and such that the substrate is foldable about the score line;
folding the substrate about the score line forming a V-shaped structure;
removing, along the score line, a portion from the folded substrate such that a first substrate portion and a second substrate portion are formed and such that the conducting path is split whereby a first electrical terminal located at the first substrate portion and a second electrical terminal located at the second substrate portion are formed;
arranging a light source in electrical connection with the first and second electrical terminals such that the light source bridge a terminal gap between the first and second electrical terminals and such that the light source is in electrical connection with the first and second electrical terminals.

13. Method according to claim 12 , further comprising assembling the folded substrate into a mechanical support.

14. Method according to claim 12 , wherein said removing of material is performed after said assembling of the folded substrate into the mechanical support.

15. Method according to claim 12 , wherein said folding is performed until the tip of the V-shaped structure is acute.
