    • The invention relates to a light-protected electrochromic device containing a pair of glass or plastic sheets or plastic films. One side of at least one of said sheets or films, preferably both sheets or films, is provided with an electroconductive coating. At least one of said sheets or films and its electroconductive coating are transparent and the other can be metallized. The electroconductive coating of at least one of the two sheets or films can be divided up into separate, individually contacted surface segments. The sheets or films are joined by a sealing ring on the sides of their electroconductive coatings and the volume created by the sheets or films and the sealing ring is filled with an electrochromic medium. The invention is characterized in that the electrochromic device contains a yellow filter for which the wavelength at which absorbance in the long-wave flank reaches half of the very long-wave maximum absorbance value is between 370 and 500 nm, preferably between 380 and 470 nm. The invention is characterized by a considerably improved resistance to light in its activated state.
    • 本发明涉及包含一对玻璃或塑料片或塑料膜的光保护电致变色装置。 至少一个所述片材或薄膜,优选两片或薄膜的一侧设有导电涂层。 所述片材或薄膜及其导电涂层中的至少一个是透明的,另一个可以金属化。 两个片材或膜中的至少一个的导电涂层可以分成单独的,单独接触的表面片段。 片材或薄膜通过密封环在它们的导电涂层的侧面上接合,并且由片或膜产生的体积和密封环填充有电致变色介质。 本发明的特征在于,电致变色装置包含黄色滤光器,其中长波侧的吸光度达到非常长的波长最大吸光度值的一半的波长在370和500nm之间,优选在380和470nm之间 。 本发明的特征在于在其活化状态下对光的耐受性显着提高。
