Abstract

A lighting device comprises a support comprising a mounting section having at least one mounting face. The at least one mounting face has an arrangement direction and comprising at least two contact sections along the arrangement direction. The support further comprises a body section adjacent to the mounting section. The support further comprises a plurality of layered conductors connecting the body section to the at least one mounting face. The lighting device comprises at least one light-emitting element mounted along the arrangement direction of the at least one mounting face such that the at least one light-emitting element is in electrical contact to the at least two contact sections.

First claim

What is claimed is:

1. A lighting device comprising:
a support comprising a mounting section having at least one mounting face, the at least one mounting face having an arrangement direction and comprising at least two contact sections along the arrangement direction;
the support further comprising a body section adjacent to the mounting section;
the support further comprising a plurality of layered conductors connecting the body section to the at least one mounting face; and
at least one light-emitting element mounted along the arrangement direction of the at least one mounting face such that the at least one light-emitting element is in electrical contact to the at least two contact sections.

2. The lighting device of claim 1 , further comprising:
a socket connected to the body section for connection to a power source.

3. The lighting device of claim 1 , wherein the body section has a length that extends parallel to the arrangement direction, such that the body section protrudes sidewards from the at least one mounting face.

4. The lighting device of claim 3 , wherein the body section has an increased cross-sectional area with increasing distance from the mounting section.

5. The lighting device of claim 1 , wherein an extension direction of the layered conductors extends substantially perpendicular to the arrangement direction of the at least one mounting face.

6. The lighting device of claim 1 , wherein the layered conductors comprises an angled section.

7. The lighting device of claim 1 , further comprising an insulating section separating two neighboring contact sections of the at least two contact sections.

8. The lighting device of claim 1 , wherein the at least one light-emitting element is configured to emit a light of different wavelength than another light-emitting element.

9. The lighting device of claim 1 , wherein a voltage is applied between any of the at least two contact sections when the body section is connected to a power source.

10. The lighting device of claim 1 , wherein at least one contact section is not connected so that a voltage is not applied to the at least one contact section when the body section is connected to a power source.
