CN2861431Y - Light modulation glass - Google Patents

Abstract

The utility model relates to a switchable light control glass, which is characterized in that the glass consists of two layers of tempered glass and one layer of LCD film. The LCD film is pasted between the two layers of tempered glass via the glue on both sides, two wires are lead out from the LCD film, the two wires are connected to the procured transformation controller, when the glass is energized, the light transmissivity is increased to more than 77%, the glass turns transparent; when de-energized, the light transmissivity is reduced to less than 12%, the glass turns vague. The advantages of the utility model are: the light is adjustable, and with a long life of service; the heat and sound insulation performance is more superior; high resistance to ultraviolet radiation, reduced light pollution, energy-saving and environment-protecting.

Description

A kind of dimming glass

Technical field

The utility model relates to a kind of dimming glass, can be used for senior door and window, car glasses, washroom and indoor and outdoor and decorates, and belongs to the glass technology field.

Background technology

At present, some families, car glasses, when the washroom needs dense glass, be in hollow glass, to add curtain to come light modulation, make and install all difficult, perhaps satisfy client's needs at utilization sandblast on glass, colored glaze, some customer requirement needs transparent sometimes, wishes opaque sometimes, often adopt white glass, add the demand that a little curtain satisfy the client in addition.

Summary of the invention

The purpose of this utility model be the invention a kind of sometimes can be transparent, sometimes also can opaque dimming glass.

For realizing above purpose, the technical solution of the utility model provides a kind of dimming glass, it is characterized in that, by two-layer tempered glass, one deck liquid crystal film lamination is formed, and one deck liquid crystal film is located between the two-layer tempered glass by the adhesive film on two sides, and the liquid crystal film is drawn two leads.

The utility model issues principle and the laminated glass and the lamination packaging technology making dimming glass of living paramagnetism or diamagnetism in External Electrical Field according to liquid crystal material, insert on the transformation controller of outsourcing drawing two leads, when glass is switched on, its light transmission rate increase reaches more than 77%, becomes transparent; When glass cut off the power supply, its transmitance was reduced to below 12%, and it is opaque to thicken, thereby reached the purpose of light modulation.

The utility model has the advantages that:

1. operation sequence is simple, and cost of manufacture is lower;

2. can light modulation, long service life;

3. performances such as heat insulation, sound insulation are more superior;

4. high anti-UV reduces light pollution, energy-conserving and environment-protective;

5. select for use different controllers can reach different control effects.

Description of drawings

Fig. 1 is a kind of dimming glass structural representation;

Fig. 2 uses schematic diagram for dimming glass.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, be a kind of dimming glass structural representation, described dimming glass is by two-layer tempered glass 1,5, and one deck liquid crystal film 3 laminations are formed.

Described tempered glass 1,5 thickness select 5mm; Described adhesive film 2,4 selects the ENA glued membrane.

Press size cutting tempered glass 1 and 5, liquid crystal film 3, the ENA glued membrane 2 and 4 of customer requirements during making.

Stick copper strips 7 at liquid crystal film 3 edges, copper strips will be paved whole, draw two leads 6, on tempered glass 5, cover one deck ENA glued membrane 4, lay liquid crystal film 3 then, lid layer ENA glued membrane 2 on liquid crystal film 3 covers watch crystal 1 at last again, and neat around the assurance layer glass, can make dimming glass through the high temperature lamination.

As shown in Figure 2, for dimming glass uses schematic diagram, the lead 6 of dimming glass is connected with light adjusting controller 8 during use, light adjusting controller 8 is connected with power supply, and the dimming glass lead-out wire divides two groups, a winding controller, another group 9,10 is standby, and glass becomes transparent during energising; During no power, glass thickens opaque, selects for use different controllers can reach different control effects.
