Abstract

A lighting module may include a printed-circuit board which via its rear side is positioned on a cooling body and on its front side is fitted with at least one light source, and at least one electronic component; a cover for at least a partial region of the printed-circuit board, with the cover being seated upon the printed-circuit board; wherein the lighting module has at least one elastic fastening element which is secured to the cooling body and positioned against the cover.

Claims

1. A lighting module, comprising:

a printed-circuit board which via its rear side is positioned on a cooling body and on its front side is fitted with at least one light source, and at least one electronic component;

a cover for at least a partial region of the printed-circuit board, with the cover being seated upon the printed-circuit board;

wherein the lighting module has at least one elastic fastening element which is secured to the cooling body and positioned against the cover.

2. The lighting module as claimed in claim 1, wherein the cover has an outward projection at least in a region in which the cover is vaulted by the at least one fastening element.

3. The lighting module as claimed in claim 1,

wherein the at least one fastening element is kept under tension.

4. The lighting module as claimed in claim 1,

wherein the at least one fastening element is applied to a top side of the cover.

5. The lighting module as claimed in claim 1,

wherein the at least one fastening element is screwed onto the cooling body.

6. The lighting module as claimed in claim 1,

wherein the lighting module has a plurality of elastic fastening elements.

7. The lighting module as claimed in claim 1,

wherein the fastening element is located at least partially in a common lateral recess in the printed-circuit board and cover.

8. The lighting module as claimed in claim 7, wherein the at least one fastening element is located completely in a common lateral recess in the printed-circuit board and cover.

9. The lighting module as claimed in claim 1,

wherein the cover is an annular cover and the at least one fastening element is secured on the outside of the annular cover.

10. The lighting module as claimed in claim 2,

wherein the cover is an annular cover and the at least one fastening element is secured on the outside of the annular cover;

wherein the projection is an edge elevation formed by an outer wall of the annular cover.

11. The lighting module as claimed in claim 1,

wherein the at least one light source comprises a light-emitting diode

12. The lighting module as claimed in claim 2,

wherein the cover has an outward, upward projection.
