Abstract: Methods and apparatus for adjusting at least one lighting parameter based on user action. For example, methods and apparatus adjust one of a minimum set point and a maximum set point in response to a user manipulation of a component of a light management system (10, 110). The adjusted at least one of the minimum set point and the maximum set point are adjusted based on a measured interior illuminance value after the user manipulation. The set points may be indicative of user desired levels of interior illuminance.

Abstract: The present invention relates to a light-transmissive element (106, 200, 500) which has light controlling properties. The light-transmissive element (106, 200, 500) comprises a plurality of first particles (206) and a plurality of second particles (208). The first particles (206) are configured to control the transmission of light of a first wavelength range being infrared light.

The first (206) and second particles (208) may independently be redistributed in an enclosure (207) enclosing the particles. Redistribution is enabled by an applied electric field which causes the particles to move in the enclosure (207). 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 (206) and second particles (208) respectively.
