Background

The light adjusting film is a novel electronic light control product, and can be switched between a transparent state and an opaque state by powering on/off. The light adjusting film is formed by injecting liquid crystal material between two transparent conductive films, when the power is off, the polymer liquid crystal is in disordered arrangement, light cannot penetrate through the films, and the films are in an opaque state; when the power is on, the polymer liquid crystals are orderly arranged under the action of a power plant, and light can penetrate through the film to be in a transparent state. The appearance of membrane of adjusting luminance makes people can control glass's transparent and opaque state at will, sets up the membrane of adjusting luminance in the middle of laminated glass, is the opaque state that has the dull polish and feels under the outage state, can protect the privacy well, is transparent state under the on-state, can provide good field of vision, and this kind of design not only has very strong science and technology to feel, has also satisfied people at the different demands of different times.

As is well known, the solar ray is mainly composed of three parts, namely ultraviolet ray, visible light and infrared ray, and in the infrared part, the energy of the near infrared ray with the wavelength between 780-2500nm accounts for nearly 45% of the total energy of the solar ray, and the part of the light is also called as heat ray.
