摘要： A diffuser unit (9) for providing a chromatically tunable transmitted light (33) by scattering of light that is incident on the diffuser unit (9) by illumination with white light (89) comprises a scattering layer (17) with a plurality of nanoscale scattering elements (19, 63) and a host material (21, 61) separating the nanoscale scattering elements (19, 63). The diffuser unit (9) further comprises a pair of areal electrical contacts (23′) for providing an electric field (27) and at least one of the areal electrical contacts (23′) is configured to be transparent in the visible wavelength range. The scattering layer (17) has a wavelength dependent ensemble light scattering cross-section amount within the visible wavelength range that depends on a relative refractive index between the nanoscale scattering elements (19, 63) and the host material (21, 61) associated to an illumination direction, and an effective size of the nanoscale scattering elements (19, 63) associated to the illumination direction. The scattering layer (17) is configured to be adaptable in the ensemble light scattering cross-section amount by varying the relative refractive index and/or the effective size of the nanoscale scattering elements (19, 63), thereby providing a changeability in the spectrum of the transmitted light (33).

摘要： The present disclosure is directed to an illumination device for providing a divergent illumination. The illumination device comprises a light source for emitting light in a visible spectrum; an output aperture, through which the light emitted from the light source exits the illumination device; and a layer structure. The layer structure comprises a scattering layer of a plurality of nanoscale scattering elements embedded in a host material and is positioned in an optical path of the emitted light that extends between the light source and the output aperture. The layer structure comprises further a pair of areal electrical contact layers, wherein the areal electrical contact layers extend at opposite sides of the scattering layer and are electrically connectable with a power source to generate an electric field across the scattering layer. The divergent illumination provided by the illumination device is characterized by at least one luminous intensity distribution curve having the full width at half maximum of at least 10°.
