<p>PURPOSE:To increase a degree of freedom is a comfortable space created by floor illumination by incorporating an electrochromic element into the floor illumination so as to enable light dimming. CONSTITUTION:Illumination light from a light source 10 enters a room by passing through a floor plate (electrochromic element). In the case of constituting the floor plate as the electrochromic element, a transparent electrically conductive film 12 such as ITO or SnO2 and an EC electrode I13 (such as WO3) are formed, for example, on a glass plate 11. A transparent electrically conductive film 16 such as ITO or SnO2 and an EC electrode II15 (such as NiOx, IrOx, Prussian blue or viologen) are formed further on the plate 11, and a plate formed in such a way that nonaqueous solvent (such as electrolytic solution of carbonic acid propylene and so on) obtained by dissolving lithium salt is sandwiched between both the films, is used as the floor plate. Particularly, as for a solid electrolytic film 14 formed by filling liquid electrolyte in a micro porous polymer thin film, a fear of the solid electrolyte leakage is hardly caused, so that electric conductivity or efficiency and so on can be improved. Thereby, light dimming of floor illumination becomes possible, and a degree of freedom in a comfortable space thereby created can be also increased.</p> |
