Description
Technical field
The present invention relates to a kind of light conductor, especially a kind of special-shaped light conductor and method for making being coated with photocatalyst optical film, can be widely used in each technical field that display, illumination, backlight etc. are relevant to area source.
Background technology
Disclosed by Chinese invention patent CN100508222C: the capacity usage ratio of the surface light source device based on light emitting diode occurred now is still lower.Be on the one hand because light emitting diode manufacturing technology itself is also at development, its power efficiency (Wall-PlugEfficiency) still has greatly improved space; LED package become on the other hand the secondary encapsulation efficiency (abbreviation secondary efficiency) of practical surface light source device also lower, and the guide-lighting efficiency low of light guide plate in light conductor is a major reason.The guide-lighting definitions of efficiency of light guide plate is the number percent accounting for the total light flux being coupled into light guide plate from total effective luminous flux of light guide plate bright dipping interarea outgoing.According to the data disclosed in the LumiledsLighting company technique publishing documents TP29 of the U.S., the secondary efficiency that a kind of area source based on large-power light-emitting diodes of the said firm designs is preferably 50%, and wherein the guide-lighting efficiency of light guide plate is about 60%.
Guide-lighting efficiency depends mainly on the general structure of light guide plate and the scattering principle of scattering machine preparative layer and structure, and the guide-lighting efficiency mentioning traditional light guide plate in United States Patent (USP) U.S.Pat.No.5396350 only has 10%-20%.This part of patent with in other several parts of patent U.S.Pat.No.5461547, U.S.Pat.No.5359691, U.S.Pat.No.5854872, propose different light guide plate and its scattering mechanism Rotating fields respectively, and improvement has in varying degrees been made to the directivity of light guide plate emergent light and guide-lighting efficiency.But, according to the document " Highly-efficientbacklightforliquidcrystaldisplayhavingno opticalfilms " of academic journal APPLIEDPHYSICSLETTERS upper 83rd phase, the highest level of the guide-lighting efficiency of existing light guide plate is merely able to reach 60%, and its scattering machine preparative layer is reflective micro-prisms array.The invalid bright dipping of this light guide plate is less, and achieves better control to the rising angle of effective bright dipping; But it still exist guide-lighting efficiency not high and make difficulty, high in cost of production problem.The existing light guide plate for primary source design is all arrange certain scattering machine preparative layer on the interarea that light guide plate is relative with outgoing interarea, utilizes light to change original reflection paths and from the outgoing of outgoing interarea to scattering unit.Although guide-lighting efficiency can be maximized by optimal design scattering machine preparative layer and scattering unit, but because light inevitably becomes invalid emergent light from the interarea transmission outgoing relative with outgoing interarea, therefore there is the upper limit of a principle and can not reach higher in its guide-lighting efficiency.
Current light conductor is only confined to the light guide plate of tabular body, guide-lighting technology is all make of mechanical engraving, printing net-point, laser engraving, special light conducting plate structure etc., still there is complex manufacturing technology, cost is high, cost performance is low, be difficult to break through the guide-lighting efficiency upper limit of above-mentioned principle, the light conductor of tabular and light guide plate application surface are also subject to certain restrictions simultaneously.
Summary of the invention
The present invention is directed to above deficiency, according to developing rapidly of geometrical optics, physioptial transmission, refraction, principle of reflection and new electric thin material and thin film preparation process technology, propose a kind ofly to implement conveniently, can raising illumination by a relatively large margin and color developing, manufacture craft is simple, cost is low, cost performance is high, and also has environmental protection, sterilization, health care, antistatic, multi-functional light conductor and the method for making being coated with optical film.
The present invention is implemented by following technical proposals
Be coated with a special-shaped light conductor for photocatalyst optical film 10, it comprises transparent solid solid 1, optical film 2, it is characterized in that:
Described optical film 2 covers transparent solid solid 1 outside surface of thickness G reatT.GreaT.GT1mm; Solid solid 1 refers to the stereoscopic article (perhaps super, yellow lead writes 2002 08 month the 1st edition " three-dimensional composition " P10 page) that the space of being filled by entity is real space.
Described solid solid 1: have at least an outside surface to be the plane of incidence 3, has at least an outside surface to be exiting surface 4; The plane of incidence 3 refers to the outside surface of light to solid solid 1 inside of light source 6.Exiting surface 4 refer to incide solid solid 1 inside light from the outside surface of the inner outgoing of solid solid 1.
On the outside surface of described solid solid 1, at least contain the deielectric-coating materials optical rete 2 of one deck sub-micron or nano particle, thicknesses of layers is at 91nm-5mm.
Because any optical film all can produce loss to light, thus reduce luminescence efficiency and the display performance of exiting surface 4.In order to reduce the loss of optical film light, particularly to the absorption loss of light, the optical film 2 of absorptivity very fractional value can have been made by existing known technology, be applied on optical device, test result as the optical thin film absorptivity that journal of Zhejiang university (natural science edition) P536 page (the 23rd in July, 1989 volume the 4th phase, " absorptivity of Pholothermal deflection spectroscopy technique detecting optical rete and calibration thereof " Chen Wenbin, Shi Baixuan, yellow-study ripple) discloses:
Particularly (Science Press publishes the 1st edition (Liechtenstein) H.K. pul Ke Er work May in 1988 to Medium Optics membrane material such as " coating film on glass ", Zhong Yongan, Xie Yushen, Wu give and seemingly translating) P356 page disclose data: the fundamental characteristics of Medium Optics membrane material is in the relevant range of spectrum, and it absorbs very low (α <10
3cm
-1).Therefore optical film 2 of the present invention is the optical films selecting Medium Optics membrane material to make, and presents α <10 when visible ray
3cm
-1the low numerical value absorption coefficient of light, substantially can meet the requirement of various different light conductor.The material of optical medium film and manufacturing technology are in Teaching Materials at College level " thin film technique " (October in 1991 the 1st edition, Wang Liheng, Huang Yuntian, Zheng Haitao writes, publishing house of Tsing-Hua University), " optical thin film " (is published for 1976, " optical thin film " is write group and is write, Shanghai People's publishing house), " optical film technique " (October in 2005 the 1st edition, Lu Jinjun, LIU WEIGUO is write, publishing house of Northwestern Polytechnical University), " novel electron membraneous material " (September in 2002 the 1st edition, Chen Guanghua, Deng Jinxiang etc. write, Chemical Industry Press), " membrane science and technical manual " (March in 1991 the 1st edition, Tsing-Hua University Tian Minbo, Shenyang Vacuum Technology Institute Liu De makes compiling, China Machine Press) have and openly introduce in detail, no longer repeat.The present invention's object is directly overlayed on the outside surface of solid solid 1 by Medium Optics membrane material, makes functional optical dielectric thin film layer.Another object is that optical medium membrane material is a kind ofly scattered in by different weight ratios in the polymkeric substance of transparent epoxy resin or transparent silicon resin parent by invention, covering on the outside surface of solid solid 1, making solid state optics medium thick film layer through being solidificated on solid solid 1 outside surface.
The functional optical dielectric thin film layer that optical film of the present invention is made up of Medium Optics membrane material more than one deck.The optical thickness of its rete is the odd-multiple of odd-multiple to 195nm of 91nm.
The present invention refers to solid state optics medium thick film layer or the functional optical dielectric thin film layer of a kind of nano titanium oxide, modifying titanium dioxide, silicon dioxide or lightweight barium sulphate through optimizing described optical film 2, and the thickness of optical film is in the thick film layers of 0.01mm ~ 5mm.
Core of the present invention substitutes traditional light guide plate with the light conductor being coated with optical film 2, therefore needs to make light conductor of the present invention to describe in detail:
The outside surface of solid solid 1, due to light source 6 be configured in the principle of the position of light conductor and the bright dipping of solid solid 1 exiting surface 4 different time, there is different functions.As Fig. 1: the outside surface of solid solid 1 is divided into the plane of incidence 3, exiting surface 4, reflecting surface 5 by function by us, reflecting surface 5 refers to the outside surface solid solid 1 internal light being reflected back again solid solid 1 inside.
The outside surface that when the present invention makes, solid solid 1 is different must cover different optical films 2.Be exiting surface 4 equally, the position configured due to light source 6 is different, also must cover different optical films 2.The method that the side entering type adopted by the position difference of current industry to backlight incident light and straight-down negative two kinds of backlighting scheme are distinguished, the position that solid solid 1 is configured in light guide plate by light source 6 by us is different, be described as follows for side entering type and straight-down negative: as Fig. 1 a: solid solid 1 is the light conductor made with methacrylate sheet, its geometric configuration is six solids in solid polyhedron, has six outside surfaces.As light source 6 is configured in hexahedral side, then this side be plane of incidence 3(if do not configured light source 6 as reflecting surface 5, therefore have two planes of incidence 3 in figure, all the other two sides are reflecting surface 5).Hexahedral two parallel external surfaces are that exiting surface 4(also can using one of them parallel external surfaces as exiting surface 4, then another parallel external surfaces is as reflecting surface 5).Light conductor in Fig. 1 b with incident sideways light, utilize the total reflection of light to carry out propagating, total reflection condition emergent light that the parallel surface of solid destroys light is then side entering type structure.
As Fig. 2 a: solid solid 1 is the light conductor in the light conductor made of methacrylate sheet, and its geometric configuration is six solids in solid polyhedron, has six outside surfaces.As light source 6 be configured in a hexahedral parallel surface then this parallel surface be the plane of incidence 3, another parallel surface is that all the other sides of exiting surface 4(are reflecting surface 5).Light guide plate in Fig. 2 b is then straight-down negative structure with solid parallel surface by the scattered beam outgoing of another parallel surface of straight line incident ray, solid.
Another object of the present invention is solid solid 1 outside surface to different optical function, covers the optical film 2 matched with known coating method, and more high-level efficiency, multi-purpose light conductor become possibility to make realization.
1) plane of incidence 3 of the present invention effective light of light source 6 is incided solid solid 1 inside, also most of light can be incided solid solid 1 inner with common optical coupling method.But also there is the reflection loss of light according to optical transmission principle at the plane of incidence 3, optical film 2 can not be covered when the ratio that the plane of incidence 3 accounts in the outside surface of solid solid 1 is little; But when the loss of the plane of incidence 3 light reflection have impact on luminescence efficiency and the display performance of exiting surface 4, just need to cover optical film 2, improve the utilization factor of light source 6 incident light, increase transmitted light, reduce the loss of the plane of incidence 3 reflected light.The optical film 2 of this performance can be implemented completely by existing known technology, as anti-reflection film, antireflecting film conventional in optical device ...As Figure 10, according to Teaching Materials at College level " thin film technique " (October in 1991 the 1st edition, Wang Liheng, Huang Yuntian, Zheng Haitao write, publishing house of Tsing-Hua University) P111 page disclose: as far back as 1817 fraunhofer (Fraunhofer) just made optic antireflecting film by the method for acid etching ... the simplest anti-reflection film is the film plating one deck low-refraction on the glass surface ...P122 page discloses: can as drawn a conclusion by above discussion:

Known by above known technology: reflection loss close to zero, also can eliminate reflection loss in wider scope or at predetermined several wavelength in theory.In order to eliminate the reflection loss of light wave λ, the optical thickness of rete must be λ/4 odd-multiple (Teaching Materials at College level " thin film technique " October in 1991 the 1st edition, the yellow fortune of Wang Li weighing apparatus is added Zheng Haitao and write, publishing house of Tsing-Hua University).
Know according to disclosed data in addition, human eye vision is under bright condition, and the green-yellow light of human eye to wavelength X=555nm is the most responsive; And under dim condition, the light of human eye to wavelength X=507nm the most responsive (" color TV lighting principle and lighting skill " publishing house of Beijing Agricultural University 1988 09 month the 1st edition executes gram filial piety in precious rich work).
The present invention is in order to eliminate the reflection loss of the most responsive light wave λ of human eye vision.Cover as the plane of incidence 3 low-index film 7 that the refractive index of optical film 2 is less than solid solid 1 Refractive Index of Material for solid solid 1 outside surface, the optical thickness of rete controls the odd-multiple at (126nm-139nm).Just can reduce the loss of the plane of incidence 3 pairs of light waves that human eye vision is the most responsive, make effective incident ray of light source 6 enter light conductor through optically-coupled extreme portions, thus improve the utilization factor of light source 6, more seem important when the plane of incidence 3 is larger especially.
The present invention is preferred further: the low-index film 7 of covering is broadband anti-reflection film.Broadband anti-reflection film refers to multi-layered antireflection coating, such as, selects MgF

3=1.62) three layers of anti-reflection film, the optical thickness of film is λ/4-λ/2-λ/4(λ is 507nm-555nm) namely the optical thickness of film be three layers of broadband anti-reflection film of (126.75nm-138.75nm, 253.5nm-277.5nm, 126.75nm-138.75nm).The optical thickness of film can be controlled three layers of broadband anti-reflection film at 126nm to 139nm, 253nm to 277nm, 126nm to 139nm to production cost by Kao Account respectively.The reflection loss of the plane of incidence 3 pairs of light waves that human eye vision is the most responsive can be reduced at whole visible-range.
2) the invalid bright dipping of light conductor inside is mainly reflected back the inside of solid solid 1 by reflecting surface 5 of the present invention in the outside surface of solid solid 1 according to optical reflection principle, and then from exiting surface 4 two outgoing, but also can realize better controlling to the rising angle of effective bright dipping, make bright dipping more even, improve the luminous intensity of exiting surface 4 further.The optical film 2 of this performance can be implemented completely by existing known technology, and reflection efficiency in theory can up to 100%.
Data according to " optical thin film " (" optical thin film " is write group and write, Shanghai People's publishing house, publishes for 1976) P116 page is announced:

In principle, this film system, to a certain wavelength, can obtain the reflectivity of infinite approach 100%.
Result of study disclosed in " optical film technique " (publishing house of Northwestern Polytechnical University October in 2005 the 1st edition Lu Jinjun, LIU WEIGUO are write) P24 page: knowing when discussing monofilm characteristic, is n in refractive index

As Figure 10, disclose according to Teaching Materials at College level " thin film technique " (1991 October the 1st edition, Wang Liheng, Huang Yuntian, Zheng Haitao write, publishing house of Tsing-Hua University) P122 page: can as drawn a conclusion by above discussion:
(1) on optical element, plate monofilm and can change its reflectivity.Incident at beam orthogonal, the optical thickness n of film
1the odd-multiple of d=λ/4(or λ/4) time, reflectivity R is maximum with the change of thin-film refractive index.And optical thickness n
1the even-multiple of d=λ/2(or λ/4) time, reflectivity R remains unchanged., λ/4 film of plating high index of refraction, R can be made to become large, reach the object increasing reflective light intensity, this film is just called the anti-film of increasing.
The reflectance coating 11 that the present invention adopts is ZrO
2+ SiO
2reflection multilayer membrane system, the optical thickness of its every tunic is the odd-multiple of odd-multiple to 139nm of 126nm respectively.
It is 507nm-555nm that the present invention adopts every layer of optical thickness to be λ/4(λ through preferred reflective coating 11) i.e. (507nm-555nm)/4, namely the dielectric multilayer-film that replaces of the high and low refractive index of (126.nm-138.75nm), considers that the optical thickness of film can control at 126nm to 139nm by production cost respectively.This is because the light beam reflected from all interfaces of rete, when they get back to front surface, there is identical bits phase, thus produce constructive interference.To such one group of dielectric coating series, higher reflectivity can be obtained, be expected in theory to obtain very close to 100% reflectivity.Particularly add the reflectivity of reflecting surface 5 pairs of light waves that human eye vision is the most responsive.(publishing house of " optical film technique " Northwestern Polytechnical University October in 2005 the 1st edition Lu Jinjun, LIU WEIGUO write P24 page).
Current reflectance coating is conventional glass microballoon type reflective membrane also, for making bright dipping more even, according to " microprism reflecting film and application prospect thereof " (highway communication science and technology phase March the 1st in 1998, Wang Zhi and, Wang Fuxin, Dan Mingzheng (Beijing Research Inst. of Aeronautic Material)) principle that discloses, reflectance coating can also control the rising angle of light with prismatic reflection film, reach the more uniform object of bright dipping.
As less demanding to reflectance coating during the present invention makes, the reflection diaphragm that the reflectivity be prefabricated into also directly can be greater than 90% by reflectance coating embeds in the reflecting surface 5 of solid solid 1, or is pasted onto on reflecting surface 5.
3) side entering type light conductor exiting surface 4 of the present invention, according to optical principle, from Figure 12 light path, side entering type light conductor is the propagation utilizing the total reflection principle of light to carry out light, know when light reflects from the medium that refractive index is high to the medium (if PMMA material is to air) that refractive index is low by light total reflection principle, the light be refracted is with the angular emission more oblique than incident ray, when incident angle is greater than a certain angle, light can not be refracted into can in the whole phenomenon occurred to internal reflection of exiting surface 4 in air.The light of light source 6 is directly transmitted in light conductor through the full optically-coupled major part of light entrance face 3, and the transmitting energy that only loss is less in the process, transmits luminous energy according to the total reflection principle of light simultaneously effectively.For its transmittance of PMMA material up to 92%, mist degree is very little, has very little light absorption, and light can be decayed very little along the very long distance of material transfer.But light cannot be drawn from exiting surface 4, therefore side entering type light conductor is the transmission utilizing the total reflection principle of light to carry out light on the one hand, the exiting surface 4 requiring on the other hand light conductor around and with it, destroy the condition of light total reflection, the ATR Optical key element of stray light changes the light path of light, light just can be made to draw from exiting surface 4, form the uniform area source of light.In current practical application, the technology of applied optics rete 2 is also less.
On light conductor of the present invention, the simplest method by experiment: for solid solid 1 outside surface as incident sideways formula exiting surface 4.What cover is the refractive index that thin-film refractive index is greater than solid solid 1, and transmittance >90%, optical thickness is the odd-multiple of (507nm-555nm)/4.I.e. (507nm-555nm)/4=(126.75nm-138.75nm) high refractive index layer 8 of odd-multiple, destroy the condition of light total reflection, the light path of the ATR Optical key element change light of stray light (write group and write by " optical thin film " [optical thin film], Shanghai People's publishing house, within 1976, publish, P5 page).Light is drawn from exiting surface 4, just can improve the luminous intensity of exiting surface 4.Particularly add the luminous intensity of exiting surface 4 pairs of light waves that human eye vision is the most responsive.
The present invention is through the optimization of test of many times, and selective refraction rate is greater than the refractive index of solid solid 1, and rete optical thickness is the functional optical dielectric thin film layer of the odd-multiple of 126nm or the odd-multiple of 139nm, transmittance >90%; Or the odd-multiple controlled respectively by the optical thickness of film at 126nm is to the odd-multiple of 139nm, the nano titanium oxide optical film 2 of transmittance >90%; Or the optics solid state medium thick film layers of nano titanium oxide, its thicknesses of layers is at 0.01mm-1mm, and transmittance >90%, covers on solid solid 1 as high refractive index layer 8.Rete presents the refractive index of more than 1.8 after testing.The transmittance >90% of exiting surface 4, luminous intensity improves greatly.
4) straight down type guide light body exiting surface 4 of the present invention, completely different from the exiting surface 4 of side entering type light conductor, from Figure 11 light path, straight down type guide light body exiting surface 4 is the transmission utilizing the direct transmission of light to carry out light, light source 6 directly transmission will inevitably produce the light pollution of direct glare, therefore straight down type guide light body exiting surface 4 is tackled transmitted light and is carried out scattering and will depart from the scattered beam in incident light direction as emergent ray, overcomes the light pollution of direct glare.
Also known as scattering film, on backlight, oneself starts the optical diffusion film applied as Patent Prospectus publication number CN1453359A disclosure to diffusion barrier is exactly one wherein.
The present invention by experiment for solid solid 1 outside surface as straight-down negative exiting surface 4, the easiest method be adopt cover containing than epoxy resin or silicones refractive index high, the light diffusing agent (as high-purity silicon dioxide powder, lightweight barium sulphate) that particle diameter is greater than visible wavelength (0.38m-0.78m) adds the transparent resins such as epoxy resin to.Can suitably control according to product thickness specification and requirement, light diffusing agent is scattered in transparent epoxy resin or transparent silicon resin parent and becomes polymkeric substance, cover after mix and blend on solid solid 1 exiting surface 4 and be cured, form the Diffusion barrier layer 9 of thicknesses of layers at 1mm-3mm.Increase the scattering of light, while covering dazzling light source 6, whole exiting surface 4 can be made again to send softer, reach the opaque comfortable effect of printing opacity.Rete mist degree >80%, diffusivity >0.6 after testing, transmittance >80%.Substantially the requirement of area source is met.
In order to the optical property improving light conductor further adds the particulate containing special wavelength in optical film 2, as fluorescent powder, optical property and the physical property of area source 6 can be improved.By experiment to the exiting surface 4 of straight down type guide light body, covering be by fluorescent powder (medium particle diameter D
508 μm-20 μm) be scattered in the thick film layers of the polymkeric substance of optical clear epoxy resin or optical clear silicone precursor, thicknesses of layers is at 0.1mm-3mm.The exiting surface 4 white light colour temperature of rete can be controlled after testing, and colour rendering index can reach more than 90.Optical property and the physical property of area source 6 are further expanded.
5) the present invention is in order to further expand the function of light conductor, as the ultraviolet light containing 365nm-410nm wavelength in light source 6, covers photocatalyst optical film 2, just can make photocatalyst component to the exiting surface 4 of solid solid 1.The area source 6 made is exactly fabulous photocatalyst lamp.
According to " illumination handbook " (Science Press, July in 2005, the 1st edition ［ day ］ illumination can be compiled, Li Nong, Yang Yanyi) the open disclosure of P103 ~ P105: for the research of photocatalyst, from before more than 20 years so far, research direction there occurs and repeatedly changes.When illumination is mapped to TiO
