CLAIMS:
1. A module for installation of a lighting unit in a recess, wherein the module comprises:
- a first body comprising a first collar;
- a second body comprising a second collar;
- at least one flexible strut; wherein the first body and/or the second body is configured to hold said lighting unit; wherein the first body and the second body are rotatable relative to each other around a rotation axis, and are positionally fixed relative to each other in the axial direction of said rotation axis; wherein the at least one flexible strut comprises a respective first end and a respective second end, wherein said first end is fixed to a respective first connection point on the first collar and said second end is fixed to a respective second connection point on the second collar; wherein the at least one flexible strut comprises a strut length, wherein the strut length is at least a factor 1.2 longer than the shortest distance between the respective first connection point and the second collar; wherein the at least one flexible strut is configured to deform in a direction away from the rotational axis when a rotation of the first body and the second body relative to each other reduces the distance between said first connection point and said second connection point.
2. The module according to claim 1, wherein the module comprises a locking mechanism configured to releasably fixate, in a locked mode of operation, the rotation of the second body relative to the first body.
3. The module according to claim 2, wherein said locking mechanism is configured to releasably fixate, in said locked mode of operation, the rotation of the second body relative to the first body when the distance between said first connection point and said
second connection point equals the distance between the respective first connection point and the second collar.
4. The module according to any one of the preceding claims, wherein the at least one flexible strut is configured to elastically deform in a direction away from the rotational axis when a rotation of the first body and the second body relative to each other reduces the distance between said first connection point and said second connection point.
5. The module according to any one of the preceding claims, wherein the at least one flexible strut is configured to plastically deform in a direction away from the rotational axis when a rotation of the first body and the second body relative to each other reduces the distance between said first connection point and said second connection point.
6. The module according to any one of the preceding claims, wherein the at least one flexible strut comprises a strut material, wherein the strut material comprises at least one of: a metal, a polymer, a composite fiber, a natural material.
7. The module according to any one of the preceding claims, wherein the at least one flexible strut comprises a strut width, wherein the strut width is at most a fifth of the strut length.
8. The module according to any one of the preceding claims, wherein the first body and/or the second body comprises a hollow interior space arranged for holding said lighting unit.
9. The module according to any one of the preceding claims, wherein the at least one flexible strut comprises a strut surface, wherein the strut surface comprises a patterned texture.
10. The module according to any one of the preceding claims, wherein the first collar and/or the second collar is circular, wherein the first collar and/or the second collar is circular comprises a diameter of at least 50 millimeter.
11. The module according to any one of the preceding claims, wherein the at least one flexible strut comprises a first strut and a second strut; wherein the first connection point associated with the first strut and the first connection point associated with the second strut are arranged antipodal to each other on the first collar; wherein the second connection point associated with the first strut and the second connection point associated with the second strut are arranged antipodal to each other on the second collar.
12. The module according to any one of the preceding claims, wherein the at least one flexible strut comprises at least three flexible struts.
13. A lighting device comprising a lighting unit and the module according to any one of the preceding claims; wherein the module is configured to be fixated in a recess when, in operation, a rotation of the first body and the second body relative to each other reduces the distance between said first connection point and said second connection point and causes the at least one flexible strut to deform in a direction away from the rotational axis; wherein the at least one flexible strut, when deformed, abuts a surface of said recess; wherein the lighting unit is configured to be mounted to the first body and/or to the second body of the module.
14. A lighting device according to claim 11, wherein the first body and/or the second body of the module comprises the lighting unit.
15. A method of installing a lighting unit in a recess, the method being performed by the module according to any one of the preceding claims 1-12, wherein the method comprises:
- positioning the module in the recess;
- deform the at least one flexible strut of the module in a direction away from the rotational axis upon rotating the first body and the second body relative to each other to reduce the distance between said first connection point and said second connection point; wherein the module comprises a locking mechanism;
wherein the method comprises:
- releasably fixate, in a locked mode of operation, with the locking mechanism, the rotation of the second body relative to the first body; wherein the at least one flexible strut, when deformed, abuts a surface of said recess for holding the module in the recess; wherein the first body and/or the second body is configured to hold said lighting unit.
