Background technology
Prior art is that each wave band produces the principle of loss after utilizing the light single to pass material or material surface adhesion layer to ultraviolet ray, ultrared absorption.Like ultraviolet radiation absorption plate, INFRARED ABSORPTION film, ultraviolet absorbing glass, infrared absorbing glass etc.
The common defects of prior art is: 1, final material only limits to plane structure, and light is only understood single and passed through, and absorbent properties can not be fully utilized, and absorptivity is not high usually.2, product can not change absorptivity according to time point or artificial demand, drops to 50% like the infrared ray absorbing rate from 90%.3, the air on planar materials product capable of blocking two sides exchanges.4, can not change the direction that sees through of light, can not utilize luminous ray.
Summary of the invention
The present invention is the shortcoming that overcomes above-mentioned prior art, and a kind of new ultrared method of absorption ultraviolet ray that is used for architectural usefulness is provided.
The ultraviolet ultrared method of a kind of absorption is characterized in that one or more elongate channel is arranged, and is fixed with the light absorbed layer on the elongate channel inwall; Light and elongate channel inwall angle are A, utilize light to pass through elongate channel, and warp is reflection-absorption ultraviolet ray or infrared rays repeatedly; Visible light transmissive is arranged simultaneously.
The present invention utilizes light to be mapped to the principle of meeting interreflection in the elongate channel; Light through being fixed with the elongate channel of UV-absorbing layer, infrared ray absorbing layer or ultraviolet infrared ray absorbing layer, is utilized the repeatedly reflection and absorbed layer repeatedly absorbs in passage of ultraviolet ray or infrared rays in the light.Shown in accompanying drawing 1.Light 2 is spent less than 90 greater than 0 degree with the inwall included angle A of elongate channel 1, and by interreflection, part light ray energy 3 is absorbed light 2 in elongate channel 1.
Like accompanying drawing 2; Be fixed with ultraviolet ray or infrared rays or ultraviolet ultrared absorbed layer 4 on the elongate channel 1, said light absorbed layer for or can absorb ultraviolet ray or can absorb infrared rays or can absorb ultraviolet ultrared dope layer, electrodeposited coating, plastic membranous layer.Its cross section of said elongate channel can be triangle or quadrangle or polygon or circular or oval, also can be other irregularly shaped or variable cross-section.When light 2 passed through elongate channel 1, every reflection once was absorbed once at absorbed layer 4.Because ultraviolet ray, infrared rays or ultraviolet infrared rays are repeatedly absorbed, and are 30% like the single absorptivity, reflect 10 times; Promptly ultraviolet ray, infrared rays or ultraviolet infrared rays are 97% through the absorptivity of this elongate channel, have greatly improved ultraviolet ray, infrared rays or ultraviolet ultrared absorptivity; Although visible light is by repeatedly reflection simultaneously; Because the single absorptivity is low, the visible light that also has larger proportion is through elongate channel 1 of the present invention.Like visible light individual reflection rate is 95%, reflect 10 times after, still have 60% visible light to pass elongate channel 5; Be that visible light has 60% percent of pass to pass through.Simultaneously since visible light with elongate channel 1 inwall included angle A when big, the ratio that is absorbed by interreflection is high, and is little with elongate channel 1 inwall included angle A hour absorbed ratio, is not absorbed basically with the approaching parallel visible light of elongate channel; So it is pass the visible light ray high conformity of elongate channel 1, and parallel with elongate channel 1.
But elongate channel linear of the present invention, also bending; And can change the visible light direction that sees through through the direction that changes elongate channel, use for different occasions such as illumination, decoration, and energy conservation.
The present invention can adjust light absorption through changing inwall included angle A size, and when the inwall included angle A of light 2 and elongate channel 1 diminished, order of reflection reduced; When the inwall included angle A of light 2 and elongate channel 1 increased, order of reflection increased.Shown in accompanying drawing 3.Accompanying drawing 3 adopts the structure same with accompanying drawing 2, has infrared ray absorbing layer 4 in the elongate channel 1.Included angle A when changing elongate channel inwall and light makes the inwall included angle A bigger, and light 2 just increases at identical elongate channel 1 internal reflection number of times, and ultrared absorptivity is just increased.Like the inwall included angle A of light 2 and elongate channel 1 is 30 order of reflection when spending 5 times, and the single absorptivity is 30%, and promptly the absorptivity through said elongate channel is 83%.When the inwall included angle A of light 2 and elongate channel 1 is 60 when spending, order of reflection is increased to 15 times, and the single absorptivity still is 30%, and the absorptivity through said elongated passage is increased to 99.5%; Promptly increase by 30 degree, ultrared absorptivity is improved 16.5% through the included angle A that changes elongate channel inwall and light.
The present invention also can select ultraviolet ray and infrared ray absorbing layer for use through changing elongate channel and light angle simultaneously, is big to ultraviolet absorptivity, and the absorbed layer low to ultrared absorptivity when being implemented in ultraviolet ray filtering, adjusted infrared rays.Equally shown in accompanying drawing 3, accompanying drawing 3 can adopt the structure same with accompanying drawing 2, but absorbed layer 4 possesses the characteristic that ultraviolet single absorptive capacity is strong, infrared rays single absorptive capacity is weak.Change light 2 and make it to diminish with elongate channel 1 inwall included angle A, light 2 reduces at elongate channel 1 internal reflection number of times, and ultraviolet, ultrared absorptivity reduces.But ultrared reduction degree is far longer than ultraviolet ray, and when ultraviolet ray still had very high absorptivity, ultrared absorptivity then obviously reduced.
Like light 2 and elongate channel 1 inwall included angle A is 60 order of reflection when spending 40 times, and ultraviolet single absorptivity is 30%, and infrared single absorptivity is 8%.I.e. ultraviolet absorptivity=(1-(1-30%) through said elongate channel
40) * 100%=99.99%, ultrared absorptivity=(1-(1-8%)
40) * 100%=96.44%; Infrared rays and ultraviolet absorptivity differ 3.56%.When light 2 and elongate channel 1 inwall included angle A reduce to 20 when spending, order of reflection reduces to 8 times, i.e. ultraviolet absorptivity=(1-(1-30%) through said elongate channel
8) * 100%=94.24%, ultrared absorptivity=(1-(1-8%)
8) * 100%=48.68%; Infrared rays and ultraviolet absorptivity differ 45.56%.This method guarantees ultraviolet ray by under most of situation of filtering, and ultrared absorptivity is adjusted as requested and very big adjusting range arranged; Can in ultraviolet ray filtering, ultrared absorptivity be regulated, utilize.
Elongate channel of the present invention can connect into array by thin-walled material each other and arrange.Shown in accompanying drawing 4, form array by above-mentioned elongate channel 1.Because each elongate channel possesses characteristic of the present invention and function, so array also possesses characteristic of the present invention.Elongate channel can further be made architectural shading, building curtain wall, architectural lighting product etc. because array has formed large-area combination simultaneously.
