Abstract
As for the problem of dynamic regulation of colors, the utility model provides an adjustable magnetic-field color changing device. The adjustable magnetic-field color changing device comprises a substrate, a color changing layer and a Helmholtz coil, wherein the substrate is made of magnetostriction materials, the color changing layer is of a raster structure, the surface of the color changing layer is rugged, and the color changing layer is located on the substrate; the substrate and the color changing layer are located in the center of the Helmholtz coil. The Helmholtz coil is powered on to generate a magnetic field; under the action of the magnetic field, the substrate stretches out and draws back to drive the raster structure to deform slightly, and therefore color changing is achieved. According to the adjustable magnetic-field color changing device, color changing is achieved by using the external magnetic field, great convenience is achieved, and good application prospects are obtained in the novel display field.
Description
Technical field
The utility model relates to the variable color devices field, refers more particularly to the adjustable variable color device in a kind of magnetic field.
Background technology
The phenomenon of variable color is present in life widely.Such as: light-sensitive sunglasses color under different light can change; The color of the skin of chameleon can change along with the change of environment.Along with the development of science and technology, in order to break through the limitation of color, people always wish that the color of device can dynamic adjustments.
The utility model content
For the dynamic adjustments problem of color, the utility model provides a kind of magnetic field adjustable variable color device, utilizes externally-applied magnetic field to realize variable color, and convenience very has good application prospect in novel demonstration field.Technical solution adopted in the utility model is that the adjustable variable color device in a kind of magnetic field, comprise substrate, photochromic layer, Helmholtz coils, wherein, substrate is the substrate that magnetostriction materials are prepared into, and photochromic layer is the optical grating construction that the surface height rises and falls, and photochromic layer is positioned in substrate; Substrate and photochromic layer are positioned at the center of Helmholtz coils.
Energising produces magnetic field to Helmholtz coils, and under the effect in magnetic field, substrate occurs flexible, drives optical grating construction little deformation occurs, and then realize variable color.The utility model utilizes externally-applied magnetic field to realize variable color, and convenience very has good application prospect in novel demonstration field.
