Abstract
The external wall element has an outer pane with lens-like holographic elements. On the inner pane, radiation receiving elements for generating energy are arranged in the focal plane of the holographic elements. The incident light may either by focused on the radiation receiving elements or on translucent portions of the inner pane. The external wall element optionally permits the generation of energy or reflection, transmission of diffuse light being effected in both cases.
Claims13
An external wall element, comprising:
- a pane having a holographic element for focusing radiation incident upon the pane, the holographic element defining a surface and a focal plane,
- a radiation receiving element spaced a distance from the holographic element and substantially in the focal plane of the holographic element, the radiation receiving element defining a surface which is smaller than the surface of the holographic element, the pane and the radiation receiving element being movable relative to one another,
- whereby a variable amount of radiation incident upon the pane may be focused upon the radiation receiving element and a variable amount of radiation incident upon the pane may be conducted past the radiation receiving element.
