Abstract
Infra-red reflecting electrochromic light controlling panel comprising, successively in laminated structure, first transparent plate, a transparent electroconductive film, an interlayer of polymer electrolyte, first tungsten oxide film, an infra-red reflecting and electroconductive metal film, second tungsten oxide film and second transparent plate. The first tungsten oxide film is colored when it is applied to negative voltage. The panel can be used as an infra-red reflecting window which regulates the transmission of visible light and solar energy by applying electric field to the first tungsten oxide film.
