Description

Electrochomeric glass

1, technical field: electrochomeric glass of the present utility model belongs to building material field.

2, background technology: sheet glass product in the market all is transparent or single constant color, and the color of the glass of having in actual applications change by the method for pad pasting, spraying as required.Even also can only remain single color by the glass that changes colour, can not or be difficult to change color with season, intensity of sunshine, people's hobby or other requirement, this kind glass can't adapt to the demand of Modern Decorative and energy saving building.

3, summary of the invention: the purpose of this utility model is to propose a kind of electrochomeric glass that can change color with season, order photograph intensity, people's hobby or other requirement.

The purpose of this utility model is achieved in that electrochomeric glass is made up of two layers of major-minor glass substrate up and down, the electrode that scribbles transparent conducting coating on its relative one side respectively and connect conductive coating, add liquid crystal coatings between glass coating, scribble the polaroid base respectively on glass two outer layer surfaces.The surrounding of glass substrate studs with the plastic-aluminum bearer bar, is provided with the printing supply lead and the attaching plug of glass substrate controller and connection electrode in this frame.Power-supply controller of electric connects one or more glass substrate simultaneously.Because liquid crystal is a kind of intermediateness material between solid and liquid, its characteristic is that the ordered state of liquid crystal molecule will change and be different optical characteristics when light sees through or is reflected.And after adding voltage on the liquid crystal layer, just can change the ordered state of liquid crystal molecule, thus light is seen through or do not see through, just can change the size of transparence by the size that changes voltage or electric current, realize the purpose of change glass colour.

Because carry out such scheme, electrochomeric glass just has the following advantages:

1. can be at any time change the depth of glass colour by controller, also can realize reducing indoor heat-energy losses, the purpose of save energy according to the depth of the automatic feed glass color of variation of outdoor intensity of illumination, envrionment temperature etc. according to people's wish.

When 2. being used for the door and window of buildings, hovels such as curtain need not be installed again, reduce space hold and installing expense.

During 3. as vehicle glass, need not paste photomask again, front windshield can change transparence according to intensity of illumination at any time, guarantees traffic safety.After the parking, all glass all become dark color, and the inside and outside people of car can't see the other side mutually.By on controller, installing the password substrate additional, can play antitheft effect, property safety in better protection vehicle and the car.

When 4. being used for the heavy construction curtain wall, can be by the variation of every electrochomeric glass substrate of computer control transparence, the image of formation motion, captions etc. on curtain wall.

5, embodiment:

Legend: 1, polaroid base 2, glass substrate 3, transparent conducting coating 4, glass modules controller 5, liquid crystal coatings 6, AC power controller 7, attaching plug 8, printing supply lead 9, plastic-aluminum bearer bar

Electronic devices and components: transformer T:220V-5V 20VA K switch 1:10V 2A single pole double throw switch adjustable resistance RT:RT1=RT2=RT3=1K Ω 0.5W photovaristor RG:RG1=RG2=1A K switch 2:10V 2A single contact turn switch chemical capacitor C:10V 3500 μ F

Embodiment: shown in Fig. 1-6, photo chromic glass is made up of two layers of major and minor glass substrate 2 up and down, main thickness of glass is greater than secondary thickness of glass, secondary thickness of glass generally is not more than 2.5mm, the printing supply lead 8 that scribbles transparent conducting coating 3 respectively and connect this coating on the relative one side of major and minor glass substrate 2, add liquid crystal coatings 5 between glass coating, the brilliant molecule of its per two discharge opeings all is 90 ° and is staggered.Posting polarizing axis on glass two outer layer surfaces respectively staggered is 90 ° polaroid base 1.Stud with plastic-aluminum bearer bar 8 around the glass substrate 2; in this frame, be provided with glass modules controller 5; this controller links to each other with plastic-aluminum bearer bar 9 AC power controller 6 outward with transparent conducting coating 3 by printing supply lead 8 respectively, and AC power controller 6 the other ends link to each other with attaching plug 7.Power-supply controller of electric 6 can connect one or more glass substrates 2 simultaneously.

As shown in Figure 1, when incident light when polaroid base 1 one sides are injected, have only axial polarized light to inject.After polarized light enters liquid crystal coatings 5, because the brilliant molecule of per two discharge opeings is staggered into 90 ° arrangement mode, make the polarized light optical axis also produce 90 ° of rotations, make the optical axis of the polarized light that enters upper strata polaroid base 1 just in time consistent with the optical axis of polaroid base 1 like this, light sees through.As shown in Figure 2, after powering up on the liquid crystal coatings 6, the Liquid Crystal Molecules Alignment direction is just parallel with direction of an electric field, and the optically-active characteristic of liquid crystal disappears.Enter upper strata polaroid base 1 polarized light optical axis just in time with the light shaft positive cross of polaroid base 1, light is blocked.

Along with the difference of institute's making alive or electric current on the liquid crystal coatings 5, will influence the transmittance of whole glass substrate 2.Decompose because liquid crystal coatings 5 can produce behind long-time connection direct current, control so glass substrate 2 adopts less than the AC power of 5V.

The principle of work of AC power controller 6 is: obtain the 5V alternating-current after the 220V civil power process transformer T step-down, deliver to K switch 1 through stopping condenser C.If the selection automatic control switch, electric current will be through adjustable resistance RT2 and photovaristor RG1; If the selection hand control switch, electric current will be through adjustable resistance RT1.After this, electric current is delivered to the K switch 2 in the glass modules controller 4, glass modules controller 4 has automatically, manually and by AC power controller 6 directly controls three selection functions, its principle of work all is by the manual shift adjustable resistance RT3 or the resistance value of coming auto-adjusting circuit by photovaristor RG2 according to light intensity, be added in voltage or strength of current on the liquid crystal coatings 5 with change, thus the transmittance of feed glass substrate 2.AC power control device 6 can be simultaneously for a plurality of glass substrates 2 provide power supply, and concentrate all glass substrates 2 of control.When being used for the large glass curtain wall, can adopt solar powered mode, to reach optimum energy-saving effect.

When have sunshine summer, glass substrate 2 will become dark color, with the transit dose of minimizing sunlight, thereby reduce the heat that produces because of solar radiation, that is the power consumption of refrigerating of having saved air conditioning machinery.When winter, glass substrate 2 will become light color, increasing the transit dose that sun does not have, thereby increase the heat that produces because of solar radiation, so just reduce the heat supplied of heating installation, reach to reduce the purpose that energy consumption and expense are paid.

The chemical name of liquid crystal coatings 6 is the N-vinylcarbazole, and molecular formula is C ₁₄H ₁₁The polarisation coating can be used the A Ermei polaroid base P80 of Wuxi AERMEI PHOTOSENSITIVE CHEMISTRY company production, directly sticks on the glass appearance surface layer to get final product.Conductive coating 3 is the light-colored conductive coatings that metallic copper, silver etc. form at surface layer of glass behind accuracy electroplate.
