Abstract
The present invention relates to a light-transmissive element () which has light controlling properties. The light-transmissive element () comprises a plurality of first particles () and a plurality of second particles (). The first particles () are configured to control the transmission of light of a first wavelength range being infrared light. The second particles () are configured to control the transmission of light of a second wavelength range being visible light. The first () and second particles () may independently be redistributed in an enclosure () enclosing the particles. Redistribution is enabled by an applied electric field which causes the particles to move in the enclosure (). Thus, transmission of light of the first wavelength range and transmission of light of the second wavelength range is thereby independently controlled by the first () and second particles () respectively.
