Abstract

A fastening element for fastening two components at one another, wherein a first component includes cut out and a second component includes a recess, wherein the fastening element penetrates the cut out and is seated in the recess to fasten a LED circuit board on a lamp component and includes a retaining clamp, wherein the retaining clamp forms a shaft wherein a shaft head is arranged at one end of the shaft, wherein the retaining clamp includes a clamping element that is arranged at the shaft head wherein the retaining clamp is provided with at least one retaining element which is configured to support the shaft in the recess of the second component wherein the fastening element includes a mounting plate in which the retaining clamp is retained in a preassembled state.

First claim

What is claimed is:

1. A fastening element for fastening a LED circuit board at a lamp component,
wherein the LED circuit board includes a cut out and the lamp component includes a recess,
wherein the fastening element penetrates the cut out and is seated in the recess to fasten the LED circuit board on the lamp component and includes a retaining clamp,
wherein the retaining clamp forms a shaft wherein a shaft head is arranged at one end of the shaft,
wherein the retaining clamp includes a clamping element that is arranged at the shaft head,
wherein the retaining clamp is provided with at least one retaining element which is configured to support the shaft in the recess of the lamp component,
wherein the fastening element includes a mounting plate in which the retaining clamp is retained in a preassembled state of the fastening element.

2. The fastening element according to claim 1 , wherein the mounting plate includes at least one centering arm which is configured to engage the cut out of the LED circuit board.

3. The fastening element according to claim 1 , wherein the mounting plate forms a contact surface for the clamping element.

4. The fastening element according to claim 1 , wherein a bottom side of the mounting plate that is oriented away from the shaft head is provided with an adhesion enhancement agent or with a solder coating by which the mounting plate is fixable at a surface of the LED circuit board.

5. The fastening element according to claim 1 , wherein the clamping element is formed by at least one spring arm which originates from the shaft head.

6. The fastening element according to claim 5 , wherein the spring arm is run under the shaft head.

7. The fastening element according to claim 5 , wherein two spring arms originate from the shaft head and receive the shaft between each other.

8. The fastening element according to claim 7 , wherein the two spring arms originate from the shaft head in opposite directions and are run in opposite directions under the shaft head.

9. The fastening element according to claim 5 , wherein the spring arm is supported with its free end in a sliding manner on the mounting plate.

10. The fastening element according to claim 2 , wherein the at least one retaining element of the shaft is configured as an interlocking spring which interlocks in a preassembled condition at a centering arm of the mounting plate.
