摘要：
A clamping element for clamping a luminaire assembly, comprising an inner section, a peripheral section, and an annular flexure section bridging the inner section and the peripheral section. The annular flexure structure allows elastic displacement of the inner section such that the flexure section, when extended, causes a clamping force between the inner and peripheral sections. The clamping element may thus be manufactured as a flat element, and in use be extended to desired height creating a biasing spring force. Thereby, one single clamping element may be used for a range of different stacks with different clamping height.
技术功效语段：
The technical efficacy of the patent scheme is that it provides a clamping element for a luminaire assembly that can accommodate different clamping heights. This allows for flexibility in manufacturing and assembly, reducing the need for multiple clamping elements.

CLAIMS:
1. A luminaire assembly comprising: a set of components arranged in a stack (21) along a central axis, and a clamping element (10; 100; 200) for clamping the stack of components in a luminaire assembly, the clamping element comprising: an inner section (11; 111; 211); a peripheral section (12; 112; 212), co-planar with and surrounding the inner section; and an annular flexure section (13; 113; 213, 215, 216) bridging the inner section and the peripheral section, said annular flexure structure allowing an elastic displacement of the inner section with respect to the peripheral section in a direction normal to a planar extension of the peripheral section, such that, when the inner section is separated from the peripheral section in said direction, the flexure section causes a clamping force between the inner and peripheral sections, wherein the inner section (11; 111, 211) abuts an outer component (22) in a back end of the stack and the peripheral section is attached to an outer component (23) in a front end of the stack, such that said components are sandwiched between the inner and outer ring sections and are clamped by the clamping force..
2. The luminaire assembly according to claim 1, wherein the annular flexure section (13; 113; 213, 215, 216) is circular.
3. The luminaire assembly according to claim 1 or 2, wherein the annular flexure section (13; 213, 215, 216) includes a set of spirally arranged flexible elements.
4. The luminaire assembly according to claim 1 or 2, wherein the annular flexure section (113) includes a set of zig-zag shaped flexure elements, each comprising two legs with opposite orientation.
5. The luminaire assembly according to any one of the preceding claims, wherein the inner section (11; 111, 211) is ring-shaped.
6. The luminaire assembly according to any one of the preceding claims, wherein the peripheral section (12; 112; 212) is ring-shaped.
7. The luminaire assembly according to any one of the preceding claims, wherein an outer edge of the peripheral section is provided with a snap-fit structure, configured to be snap-fitted to an outer component of a stack of components.
8. The luminaire assembly according to any one of the preceding claims, wherein the inner section, the peripheral section, and the annular flexure section have all been formed as separate parts, which parts have been assembled to form the clamping element.
9. The luminaire assembly according to any one of the preceding claims, formed as a flat element made of one integral piece.
10. The luminaire assembly according to claim 9, wherein the flat element has been formed from a sheet material, such as sheet metal or plastic.
11. The luminaire assembly according to claim 9, wherein the flat element has been 3D-printed.
12. The luminaire assembly according to any one of the preceding claims, wherein the annular flexure section includes a first annular flexure section (213) and a second annular flexure section (216) oriented oppositely to the first annular flexure section, and an intermediate section (215) between said first and second annular flexure sections (213, 216).
13. The luminaire assembly according to any one of the preceding claims, wherein the set of components includes a heat sink (22), a reflector (24) and a front side rim (23), and wherein the peripheral section (12; 112; 212) is attached to said front side rim (23).
14. The luminaire assembly according to claim 13, wherein the front side rim comprises a snap-fit structure, and the peripheral section is snap-fitted into the front side rim.
15. A clamping element suitable for use in the luminaire assembly according to claim 4 or 12.
