METHOD AND CONTROLLER FOR MANAGING ELECTROCHROMIC LIGHT-MODULATORS WITH THIN-FILM ELECTROCHROMIC AND / OR CHARGING BUFFER LAYERS Russian patent published in 2018 - IPC G02F1/163 

FIELD: control systems; lighting equipment.

SUBSTANCE: invention relates to electronic devices for controlling electrochromic light modulators (ECLM) intended for controlling the flux of light and radiant heat energy. Way ECLM is managed is that, as a necessary and sufficient criterion for the generation of a regulating influence, the correlation of the optical transmission of the ECLM with the voltage arising at the ECLM as a result of its charge by direct electric current or its discharge by short-circuiting the anode and cathode is used. Controller implementing this method is designed to control ECLM based on thin-film electrochromic and charge-buffer layers separated by a layer of optically neutral electrolyte. Controller contains six function blocks: the unit for determining the required operating voltage (Up) on the ECLM, depending on the illumination and / or user-defined, block for determining the safe voltage range (Ub) for ECLM as a function of temperature, the first comparator unit, the second comparator unit, the charge / discharge ECLM unit, the relay unit. In this case, the range of safe voltage values on the ECLM is determined by the difference in potentials of the electrochemical reactions occurring at the cathode and the anode of the light modulator at the current temperature of the ECLM.

EFFECT: reduction of the complexity of the controller for ECLM management in order to increase the reliability of its operation and the accuracy of the regulatory impact on the basis of a more adequate assessment of the state of ECLM during operation.
