Abstract
(EN)
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.

Le but de la présente invention est de fournir un dispositif de commande de miroir électrochromique capable de : résoudre un problème de chauffage par application d'un procédé de commande de courant au lieu d'un procédé de commande de tension ; et à fournir de manière stable un courant et une tension d'une valeur souhaitée à un miroir électrochromique indépendamment d'une tension d'entrée. Selon la présente invention, le dispositif de commande de miroir électrochromique peut comprendre : une unité de capteur d'éclairage pour détecter la luminosité de la lumière ; une unité MCU pour délivrer en sortie un signal de commande correspondant au niveau de luminosité de la lumière détectée ; une unité de commande ECM pour générer et délivrer en sortie, en réponse au signal de commande, un courant constant ayant une valeur de courant qui varie en correspondance avec le niveau de luminosité de la lumière détectée ; et un miroir électrochromique comprenant un matériau, qui est oxydé par le courant constant émis par l'unité de commande ECM et provoque un changement chimique changeant de couleur, et ayant une réflectivité qui est ajustée en correspondance avec la valeur de courant variable du courant constant.
