METHOD FOR SEASONAL CALIBRATION OF LIGHT TRANSMISSION OF SMART WINDOW WITH GRID OPTICAL FILTER Russian patent published in 2022 - IPC G02B5/20 E06B9/24 

FIELD: architecture and construction.

SUBSTANCE: invention is applicable in architecture and construction for angular selective self-regulation of window light transmission with adaptation to the trajectory of the sun relative to it and taking into account seasonal changes in the angle of incidence of sunlight on the window surface. Taking into account the trajectory of the sun relative to the window on the selected day of the year with the maximum requirements for sun protection, the widths of the bands of the smart window with a two-grid optical filter and their location on both gratings, as well as the slope of the grating strips with respect to the horizontal axis of the plane are calculated windows at an angle ranging from 0 to 90° to ensure a minimum window light transmission at the selected time of the settlement day. Additionally, the temporal characteristics of the light transmission of the window are calculated for any other days of the year with different positions of the two gratings relative to each other vertically to ensure optimal light transmission of the window on these days. The most suitable arrangement of two gratings relative to each other vertically is determined to obtain satisfactory temporal characteristics of light transmission, and one of the glasses of the smart window with the grating is moved vertically.

EFFECT: invention provides the possibility of optimized angular regulation of the light transmission of the window with adaptation to the trajectory of the sun relative to it, with the minimization of light transmission at the selected time of the selected day and with the optimization of light transmission on other selected days of different months of the year.
