Title:
ELECTROCHROMIC MIRROR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/111683
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrochromic mirror control device capable of: resolving a heating problem by applying a current control method instead of a voltage control method; and stably providing a current and a voltage of a desired value to an electrochromic mirror regardless of an input voltage. The electrochromic mirror control device according to the present invention can comprise: an illumination sensor unit for sensing the brightness of light; an MCU unit for outputting a control signal corresponding to the brightness level of the sensed light; an ECM control unit for generating and outputting, in response to the control signal, a constant current having a current value that varies in correspondence to the brightness level of the sensed light; and an electrochromic mirror including a material, which is oxidized by the constant current outputted from the ECM control unit and causes a color changing chemical change, and having reflectivity that is adjusted in correspondence to the varied current value of the constant current.
