Double-layered cavity type liquid color-change glasses

Abstract

The invention provides a pair of double-layered cavity type liquid color-change glasses. The pair of double-layered cavity type liquid color-change glasses comprises a glasses frame, lenses, colorless fluid executing mechanisms, colored fluid, colorless fluid, elastic thin films, colorless fluid cavities, colored fluid cavities and elastic colored fluid storage cavities, wherein the inner part of each lens is composed of one colorless fluid cavity, one colored fluid cavity and one elastic thin film, and the colorless fluid cavity and the colored fluid cavity are separated by the elastic thin film; the colorless fluid executing mechanisms are mounted on the two sides of two glasses legs of the glasses frame; the colorless fluid is stored in the colorless fluid executing mechanisms and the colorless fluid executing mechanisms are connected with the colorless fluid cavities by pipelines; the elastic colored fluid storage cavities are mounted on the inner sides of the two glasses legs of the glasses frame; the colored fluid is stored in the elastic colored fluid storage cavities; and the elastic colored fluid storage cavities are connected with the colored fluid cavities by pipelines. According to the double-layered cavity type liquid color-change glasses, the circulating flowing of the colored fluid between the lenses and the storage cavities is controlled by the deformation of the thin films, caused by the pressure change of the colorless fluid in the cavities, so that the colors of the lenses are changed.

Description

technical field

[0001] The invention relates to liquid color-changing glasses with double-layer cavity. Background technique

[0002] At present, the color-changing glasses on the market mainly use solid color-changing materials, and these materials show different structural states under different light intensities. For example, silver bromide, when the light is strong, the silver bromide will decompose into bromine and silver particles, making the lens appear a darker color and protecting eyesight; and when the ambient light is weak, bromide ions And silver ions will synthesize silver bromide under the action of catalyst copper oxide, and restore the original transparent color of the lens. However, the main disadvantages of this solid photochromic mirror are: (1) The discoloration speed of the solid photosensitive material is relatively slow; (2) It is difficult to completely return to the original transparent color after the discoloration is completed; (3) The discolorati...
