Description

A kind of intelligent glass
Technical field
The present invention relates to a kind of light modulation device, particularly relate to a kind of intelligent glass.
Background technology
In recent years, not only novelty attractive in appearance, but also can printing opacity, to keep out the wind and the glass curtain wall of blocks dust, glass roof, glass structure have become the notable feature in modernism skyscraper epoch.But common building glass can not adjust self performance automatically to adapt to the environmental changes such as wind, rain, light, brings inconvenience to us.Therefore, people, when selecting building glass, except considering its aesthetic characteristic and external appearance characteristic, more focus on the problems such as its heat controls, the comfortable balance of freeze cost and the projection of inner sunlight.Under the trend that novel building develops towards intelligent direction, " intelligent glass " of dynamic regulating illumination intensity and indoor temperature becomes rapidly the focus of various countries' research.
So-called intelligent glass, it is a kind of light modulation intelligent device be made up of the base materials such as glass or other transparent material and light control material, under certain physical condition, as conditions such as illumination, electric field, temperature, can be there is painted or color fading reaction in device, change the color state of self, thus the heat radiation of absorption or reflect ambient is spread with prevention internal heat selectively, reach the object reversibly regulating light intensity and indoor temperature, be expected to be used in family of future generation or commercial windows.
Generally for the object realizing sunlight transmittance and reflectance, the means of employing are plated films on glass, make the light of certain section of wavelength in light by glass-reflected or transmission, and according to different reflective and printing opacity demands, can take the film of unlike material.Such as low emissivity glass, be the film system be made up of the metals such as multilayer silver, copper or tin or its compound in glass surface plating, product has higher transmissivity to visible ray, has very high reflectivity to infrared ray, has good heat-proof quality.But low emissivity glass is generally single flat glass sheet, there is following shortcoming: film strength is poor, impact resistance be poor, in carrying and installation process easily contaminated and scratch, light transmission is strong, reflectivity is high, light pollution is large, heat insulation performance is low, film plating layer easily comes off affects serviceable life etc.The most important point is, people want to be realized by intelligent glass cool in summer and warm in winter, especially to make a clear distinction between the four seasons area in China's major part, this demand is more urgent, but coated glass cannot meet this demand, because coated glass is once structure is formed, its optical property just can not carry out reversible adjustment, and its optical property can not change with environmental change or personal like.In like manner, coated glass also cannot enable the light transmission from glass again of this section of wavelength under can meeting the prerequisite reflected the light of certain section of wavelength in visible ray after shaping.The reflectorized material that coated glass adopts simultaneously is the ionic crystal based on metal and doped metallic oxide mostly, the reflectorized material forming this glass easily disturbs navigation and communication system, and this shortcoming is unfavorable for that coated glass window worldwide carries out universal and widespread use.
At present, market also has some carried out the product of light modulation by electric field action, as liquid-crystalline glasses and electrochomeric glass, but they have some defects separately, limit it and apply.Liquid-crystalline glasses makes the orientation of liquid crystal molecule become regular by voltage effect, thus the color realizing liquid-crystalline glasses from opaque become transparent, liquid-crystalline glasses fast response time, but virgin state is opaque, need energising just can change clear state into, required voltage is high and energy consumption is large.Electrochomeric glass is the adjustable intelligent glass of the color that utilizes the electrochromic property of material to make and heat radiation transmitance, so-called electrochromism refers to that material causes redox reaction by electrochemical process and produces the phenomenon of reversible color under the effect of electric field and electric current; Electrochomeric glass has the low advantage with there being memory for color effect of energy consumption, but its existence involves great expense, response speed is slow, the color retention time is short, cyclic reversibility is poor, the problem of processing complicated process of preparation.
Existing intelligent glass product often expensive, response time comparatively slow, complicated process of preparation and second-rate on the market, be difficult to be widely used in a large amount of building, develop a kind of can environmentally to change or personal like carries out the intelligent glass of modulation at any time, a kind ofly can to have very important significance to the intelligent glass that the light modulation demand of people responds at any time, also there is very large application value.
