Abstract
The utility model relates to one-way privacy glass which comprises two layers of base glass. A liquid crystal light adjusting film is arranged between the two layers of base glass. A conductive band is arranged on the liquid crystal light adjusting film and forms a control circuit with a switch device and a power device. The one-way privacy glass has the advantages that in a power-on state, the liquid crystal light adjusting film is transparent, the glass is one-way glass or transverse glass and has good view conditions; in a power-off state, the liquid crystal light adjusting film is free of shadow-marks, and the glass is in a human eye two-way closing condition.
Description
Technical field
The utility model relates to a kind of unidirectional dimming glass.
Background technology
The overall development trend of building glass is energy-conservation, safety, environmental protection, health, fashion.Modern office and living environment more and more need to have the space of open and concealed dual-use function, the space that a kind of specific glass can realize an opening disappears invisible at once, also can allow hidden scene moment rise before one's eyes, and this variation only need click switch, can realize, this is dimming glass.But dimming glass is to realize two-way transparently or opaque, realize one-way transparent or opaque, and these dimming glass are not enough to meet the demands.
Utility model content
The purpose of this utility model is to provide a kind of unidirectional dimming glass, to overcome prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A unidirectional dimming glass, comprises two-layer parent glass, between two-layer described parent glass, is provided with liquid crystal light modulation film, and described liquid crystal light modulation film is provided with conductive strips, and described conductive strips and a switchgear and a supply unit form a control loop.
Further, described parent glass bonds by EVA film and liquid crystal light modulation film.
Preferably, two-layer described parent glass one deck is float glass, and another layer is single plane fluoroscopy coated glass.
The beneficial effects of the utility model are: have disguise and opening, can single plane fluoroscopy and hidden, outdoorly can't see indoor scenery, but indoorly can see outdoor scenery clearly, or outdoor can see indoor, indoor can't see outdoor, when indoor or outdoors is thought hidden its outdoor or indoor scenery, can power-off make dimming glass opaque carry out hidden.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the off-position schematic diagram of unidirectional dimming glass described in the utility model embodiment;
Fig. 2 is the "on" position schematic diagram of unidirectional dimming glass described in the utility model embodiment.
In figure:
1, parent glass; 2, liquid crystal light modulation film; 3, switchgear; 4, supply unit; 5, EVA film.
Embodiment
As shown in Figure 1, a kind of unidirectional dimming glass described in the utility model embodiment, comprise two-layer parent glass 1, between two-layer described parent glass 1, be provided with liquid crystal light modulation film 2, described liquid crystal light modulation film 2 is provided with conductive strips, and described conductive strips and a switchgear 3 and a supply unit 4 form a control loop.Described parent glass 1 is by EVA film 5 and liquid crystal light modulation film 2 bondings.
While making this glass, first follow according to installation dimension cutting parent glass 1, carry out edging cleaning-drying, then cutting liquid crystal light modulation film 2 and EVA film 5; On sheet platform, put one deck float glass, common white glass or ultrawhite closing; then at laying one deck EVA film 5 on glass; on EVA film 5, lay again liquid crystal light modulation film 2 and conductive strips; on liquid crystal light modulation film 2 and conductive strips, lay again one deck EVA film 5; half mirror is laid by the superiors; then putting into vacuum bag vacuumizes; put into the heating of EVA doubling stove; adjust temperature, time; make being bonded together of EVA film and glass, liquid crystal light modulation film close; then cooling coming out of the stove, product machines.
During concrete use, under deenergization state, effect because of liquid crystal light modulation film 2, glass both sides can't see per capita the other side, under "on" position, due to the acting in conjunction of liquid crystal light modulation film 2 and single plane fluoroscopy coated glass, the people who is positioned at single plane fluoroscopy coated glass one side can see the scenery of opposite side, and the people who is still positioned at simple glass one side but can't see the scenery of single plane fluoroscopy coated glass one side.
Liquid crystal light modulation film 2 has utilized the electricity of liquid crystal to cause transmission, scattering phenomenon, makes dimming glass possess transparent, the opaque function of power-off printing opacity of energising.Unidirectional dimming glass has also possessed arbitrarily other characteristics of laminated glass between transparent and opaque in handoff functionality having realized: security, unidirectional dimming glass is when being subject to impact grinding, on film in the middle of glass fragment is bonded at, can not damage the person; Sound-proofing, liquid crystal light modulation film and EVA in the middle of dimming glass have sound dampening effect, can effectively intercept all kinds of noises; Environmental protection characteristic: shielding of ultraviolet, dimming glass layer structure can stop more than 90% ultraviolet ray, can protect indoor displaying articles, avoids because of fading of causing of UV radiation and aging; Power save properties: transparent during energising, not shadow-mark of printing opacity during power-off, the in the situation that of protection privacy, light is still abundant, and the reception room of Shen Zang Office Area is still bright, not only comfortable, and has saved power for illumination; Projection property: under closed condition, visible ray nephelometric turbidity unit reaches more than 43%, transmitance reaches more than 50%, can be used as projection screen and uses in overlooking market, plays good advertising results.If projection under opening, also has three-dimensional dimly discernible effect.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
