专利汇可以提供Electrochromic (ec) mirror which rapidly changes reflectivity专利检索,专利查询,专利分析的服务。并且Electro-optical device useful in modulation of reflected light, and the like, typically comprising an electrochromic device containing a reflecting mirror surface, said electrochromic device being a sandwich arrangement of a transparent electrode, an electrochromic layer, a reflecting and support layer disposed in a liquid electrolyte and a counterelectrode. The electrochromic device exhibits coloration and bleaching thereof at ambient temperature by control of the polarity of an applied electric field, whereby light reaching the reflecting layer electrode is modulated in intensity, thus modulating, in turn, the reflected light.,下面是Electrochromic (ec) mirror which rapidly changes reflectivity专利的具体信息内容。

  • 2. The device of claim 1 wherein said persistent electrochromic material is tungsten oxide.
  • 3. The device of claim 1 wherein said persistent electrochromic material is molybdenum oxide.
  • 4. A variable light transmission process as defined in claim 1 comprising control means coupled to said device for selectively applying across said electrodes a potential of one polarity, a potential of opposite polarity and an effective short circuit.
  • 5. The device of claim 4 wherein at least one of the selectively applied potential is variable over a given range.
  • 6. The device of claim 5 wherein said control means is put into operation by photoactivatable means activated by the radiation to be reflected.
