Abstract:
Described is a holographic film (100) whose transmission and/or reflection properties vary periodically along at least one of its directions of principal extent, said film being designed for at least partial transmission (22, 28) of light (20, 26) of at least one first wavelength range that is irradiated from a multiplicity of periodically disposed illuminants (200) and that impinges on the holographic film (100). Also described are a lighting means (300), a backlighting means and a method for producing a holographic film (100).
