するＥＣミラーの光反射率制御装置。 A light reflectance device configured to change the light reflectance of the mirror by disposing an electrochromic element to cover the reflective surface of the mirror and applying different voltages to the electrochromic element to create different colored states. A control device, comprising voltage supply means for applying different voltages corresponding to the coloring states to the electrochromic element, and selecting a voltage corresponding to a specific coloring state among the coloring states by activation or inactivation. a plurality of voltage selection means for outputting selection signals for outputting a specific voltage; and a first voltage selection means for outputting a control signal for causing the voltage supply means to output a specific voltage based on the plurality of selection signals.
control means, and based on the plurality of selection signals,
a second control means that recognizes whether the plurality of voltage selection means are activated or deactivated and outputs a switching recognition signal; and a second control means that supplies the voltage to the electrochromic element based on the control signal and the switching recognition signal. or a switching means for selectively connecting the electrochromic element to the ground, the switching means being configured to connect the electrochromic element to the ground only during a certain period of time when the switching recognition signal is input. A light reflectance control device for an EC mirror characterized by the following.
