<p>The element has a reflective layer (3) e.g. conical shaped reflective layer, on an elastically deformable support, and a deformation apparatus for elastically deforming the support. The support has an elastically deformable flat, shell-shaped supporting structure (2) provided with bent wires (4), where the wires are subjected to bending stress. The support has a support layer made from a rubber material i.e. vulcanized rubber. A tensioning apparatus (6) i.e. quick-action spanner, tensions a tensile element e.g. non-transparent tension wire (5), and relieves the tensile element of tension. The tensile element is made from nylon or transparent polymer. An independent claim is also included for a light-emitting apparatus comprising an optical element.</p> |
