Abstract
The utility model introduces a daily article, particularly a double-layer polarized film with adjustable transparency. The utility model has the realization principle that the utility model uses the light filtering performance of a polarized color filtering film, and the surface of each film is divided into parallel strip-shaped areas, the width of which are equal; polarized color filtering films with different polarization directions are respectively arranged on each area; two films cling, or few gaps are remained between the two films; via moving the films, the relative position of areas of the polarized color filtering films with different polarization directions is changed, so after rays are permeated through the two the films, the strength of the rays is changed.
Description
Affiliated technical field
The utility model relates to a kind of daily necessities.So-called transmission be meant that promptly material stops the ability of light, such as light glass transmission is high, and the dark glass transmission is low.
Background technology
The example that needs to change exposure intensity in the daily life is a lot, draws the curtain together when shining such as the sun, also can use window shutter when needs are regulated light.But window shutter is to change transmission area, is not to change transmission.
Summary of the invention
The utility model is the double-deck polarization film of a kind of adjustable transmission, realizes regulating the purpose of transmission by the relative position that changes double-layer films.
The utility model has utilized the optical filtering performance of polarization filter film, and as shown in Figure 1, the light wave (1) vertical with polarization filter film direction when direction of vibration passes through polarization filter film (3), and light wave is stopped fully; The light wave (2) parallel with polarization filter film direction when direction of vibration passes through polarization filter film (3), and light wave passes through fully.As shown in Figure 2, the light wave that becomes 45 degree when direction of vibration with polarization filter film direction is by polarization filter film (4), and light wave is partly stopped.
The technical solution of the utility model just is based on the transmission principle of polarization film, its film is double-deck, every layer structure as shown in Figure 3, the surface of film is divided into the parallel strip zone that width equates, each zone is the different polarization filter film of direction, its order of shaking direction thoroughly be level, left to bottom right, vertically, the lower-left is to upper right.During use two films are close to or stay less slit, change the relative position in different directions polarization filter film zone by mobile film, thereby change the intensity after light sees through two films.The regulating action of this bilayer film can be divided into three kinds of situation explanations, first kind of situation is when mobile film makes the parallel direction region alignment, as shown in Figure 4, light is by the ground floor film, filter a part of light, during again by second layer film, because this moment, its light wave direction of vibration was consistent with the polarization film direction, light is no longer filtered.Second kind of situation is when the polarization film direction becomes the region alignment of miter angle, and as shown in Figure 5, light is by the ground floor film, filter a part of light, during again by second layer film, because this moment, its light wave direction of vibration became 45 degree with the polarization film direction, light is filtered a part once more.The third situation is when the vertical region alignment of polarization film direction, and as shown in Figure 6, light is by the ground floor film, filter a part of light, during again by second layer film, because this moment, its light wave direction of vibration was vertical with the polarization film direction, light is stopped fully.Except that above three kinds of situations, when polarized regions is not exclusively alignd, the admixture that first kind, second kind or second kind, the third situation will occur, the amplitude of its transmission are also between between the projection degree under first kind, the second kind situation or between the transmission amplitude under second kind, the third situation.This shows,, can reach the purpose of regulating transmission by changing the relative position of two films.
The beneficial effect of this utility model is, regulates transmission more easily, and this film can be attached on the windowpane or make curtain.

Embodiment
Film is double-deck, every layer structure as shown in Figure 3, the surface of film is divided into the parallel strip zone that width equates, each zone is the different polarization filter film of direction, its order of shaking direction thoroughly be level, left to bottom right, vertically, the lower-left is to upper right.Two films are close to or stay less slit, change the relative position in different directions polarization filter film zone by mobile film, thereby change the intensity after light sees through two films.
Claims (1)
- The double-deck polarization film of a kind of adjustable transmission, it is characterized in that: the surface of film is divided into the parallel strip zone that width equates, each zone is the different polarization filter film of direction that shakes, two films are close to or are stayed less slit, and change the relative position in the different direction polarization film zones that shake thoroughly by mobile film.
