摘要： The invention concerns an adjustable reflector (1) which comprises a plurality of reflector elements (2) which each have a reflector surface (3) and are pivotably disposed. The reflector elements (2) can pivot in at least two directions and/or are mutually coupled and pivotable together. The reflector surface (3) can comprise a tensioned aluminium or silver foil. The reflector elements (2) can be at least partially transparent spheres. According to a further configuration, the reflector surface is disposed in an equatorial plane of the spheres. It can be produced in a particularly advantageous manner from the point of view of manufacturing techniques if the spheres are each assembled from two hemispheres, the reflector surface being formed on the flat surface of one of the two hemispheres. Preferably, in order to be parallel and jointly pivotable, the reflector elements can be coupled in a particularly structurally simple and elegant manner if, according to a further advantageous embodiment of the invention, the spherical reflector elements are clamped between two plane parallel plates of which at least one is made of a transparent material. If one of these two plates is displaceable relative to the other plate whilst the spacing therebetween is maintained, a corresponding displacement rotates the spherical reflector elements, clamped between the two plates, in the same direction, such that the surface normal of their reflector surface is adjusted or pivoted in the desired manner.
