Claims (1)
した透過率可変なサングラスにおいて、高設定電
圧値以上で透過率を高から低にする信号を出力し
低設定電圧値以下で透過率を低から高にする信号
を出力するようなヒステリシス特性を持つた電圧
検出回路を持ち、そのヒステリシス領域内で設定
電圧値に関係なく透過率を高から低に、又は低か
ら高に変えるスイツチを少なくとも１つ持つこと
を特徴とする電子サングラス。 Sunglasses with variable transmittance that utilize the electro-optic effect of liquid crystals and the electromotive force of solar cells output a signal that changes the transmittance from high to low when the voltage is higher than the high set voltage value, and from low to low when the voltage is lower than the low set voltage value. It has a voltage detection circuit with a hysteresis characteristic that outputs a signal that increases the voltage, and has at least one switch that changes the transmittance from high to low or from low to high within the hysteresis region regardless of the set voltage value. Electronic sunglasses characterized by having.
