Description

Device with thermal insulation film

The invention relates to a device with a heat-insulating light-guiding film, in particular to a window device with an adjustable light source and a light amount incident on the room, to which a heat-insulating light-guide film is attached.

Generally, a multi-layer film is composed of a plurality of layers of different refractive index films, and a plurality of films can be combined to produce a small amount of effects, such as heat insulation, filtering, polarizing, anti-glare, etc. The multilayer is composed of a film which is not made of a material, and the main component is a high molecular polymer.

Taking the heat insulation effect as an example, the heat insulation film achieves the effect of heat insulation by reflecting or absorbing solar heat energy, mainly by reflecting or absorbing infrared rays through a special material in a plurality of layers of film, for example, forming on the surface of the multilayer film. Metal reflective coatings, such as silver, titanium, iron, aluminum, etc., can directly reflect energy out of the room. Although such reflection heat insulation can block solar heat, it also causes indoor reflection. If the solar heat is absorbed, the heat may accumulate in the heat-insulating film and may cause heat to be released twice, resulting in a problem of poor heat insulation.

For a related example of the heat-insulating film, reference may be made to a nanostructure optical insulating film disclosed in the Republic of China Patent No. I346215 of August 1, 2011, the proposed optical insulating film is provided at the base.

The cross-section of the surface structural layer preferably exhibits a geometric shape extending over the entire surface of the substrate and is a columnar structure extending over the surface thereof. The columnar structure may be a single or mixed plurality of columnar structures.

In another embodiment, the multilayer film film body may be composed of one or more multilayer film modules having individual functions, and each of the multilayer film modules is composed of a plurality of layers of films of different refractive indices.

The effect of the heat insulation can be adjusted by adjusting the material composition and thickness of the multilayer film body 205 to control the light band to be reflected, such as the infrared light band or the ultraviolet light band.

For an example, reference may be made to the schematic diagram of the thermal barrier film shown in FIG. The heat insulating light guiding film comprises a surface structural layer 301 disposed on the surface, the main function of which is to effectively guide the light to a specific direction, and the portion of the multilayer film body 32 can be modularized, that is, one or more The functional multilayer film modules (303, 305, 307) are combined into a multilayer film body 32 as desired.

The multilayer film body 32 of this example includes a first multilayer film module 303, a second multilayer film module 305 and a third multilayer film module 307, and each of the multilayer film modules is also laminated through a plurality of layers. Adjacent to films of different refractive indices, the thickness and the design of each layer of material (refractive index) are isolated or pass through a specific band of light, including insulation, color change, polarization, glare, guiding light, etc. The film body 32 can be composed of one or a plurality of individual multi-layer film modules having specific functions according to requirements, so that a plurality of functional film bodies can be formed, including simultaneously insulating heat, polarizing and/or blocking various optical bands. The light and so on. Each of the multilayer film modules can also be extruded in a co-extrusion process, or layer by layer, and then laminated. Through the design of multi-function multi-layer membrane modules, it can produce effects such as filtering specific optical bands, polarizing, and heat insulation (such as blocking infrared light or ultraviolet light).

The surface of the multilayer film body 32 is provided with a surface structure layer 301, which is formed in the following manner and is applicable to the embodiments of the above respective multilayer film structures.

The process includes coating a polymer material on the surface of the multilayer film structure by using a coating method on one side of the completed multilayer film structure, and then using an imprint method to imprint the template with a surface pattern or a roller; or first The film having the surface structure is formed, and then adhered to the multilayer film structure with a transparent glue. The transparent glue can be an optical glue, such as UV glue, which can be shaped and bonded by photocuring, pressure sensitive adhesive or heat curing.

In the embodiment shown in FIG. 3, a substrate (not shown in FIG. 3) may be disposed between the surface structure layer 301 and the multilayer film body 32. The material of the substrate and each layer is thermoplastic polymer polymerization. Such as polymethyl methacrylate (PMMA), polycarbonate (PC), methyl methacrylate (Styrene, MS) and polystyrene (PolyStyrene, PS), and polyethylene (Ethylene Terephthalate), PET, polyethylene (Ethylene Naphthalate), PEN, polypropylene (PP), etc. At least one material of the group of materials or a copolymer thereof, but not limited to the above. The materials described herein can be applied to the various layer structures of the thermal barrier film disclosed in each of the above embodiments.

The above embodiments can be applied to a co-extrusion process in which a multilayer film structure is formed, and the multilayer high molecular polymer material film in the heat insulating light guiding film is uniaxially or biaxially stretched through an extension process, and can be used in a polymer material. The effect of the refractive index difference in each direction is formed between the respective optical film layers, so that the film in the heat insulating light guiding film has the characteristics of different refractive indices in the X and Y directions on the plane, or has a different refractive index from the vertical Z direction. characteristic. The biaxial extension of the material forming the birefringent material layer is performed by an extension process, wherein the biaxial extension longitudinal direction (MD) may be extended several times, the lateral direction (TD) may be extended several times, or the simultaneous biaxial extension longitudinal and lateral directions may be used. The extension is several times, and the different layers after stretching have a certain refractive index difference.

Next, as shown in FIG. 4A to FIG. 4E and the like, the surface of the heat insulating film is The structure can be designed in a variety of ways depending on the needs and the applicable environment.

The embodiment shown in FIG. 4A to FIG. 4E and the like shows that the surface structure section substantially presents a geometrical structure, such as a regular or irregular geometric shape such as a triangle or a polygon, and the section extends out of a whole column structure on the surface of the structure. That is, the structural body having a geometric shape extends over the surface of the above substrate or multilayer film film body.

As shown in FIG. 4A, with respect to the normal line of the vertical surface, the apex of the approximately triangular surface structure 401 is taken as the standard, and the inside forms two angles (θ ₁ and θ ₂ ) with respect to the normal, wherein the light source 40 The surface structure 401 is entered by the side forming the angle θ ₁ to form an angle θ ₄ with the normal. In order to achieve the effect of guiding light penetration and refracting upward, the refractive index of the material is about 1.5 according to the results of the light path experiment, wherein if θ _{1 is} about 18 to 30 degrees, θ _{2 is} preferably about 19 to 27 degrees. This example effectively directs light from one side (outdoor light) through the design of the substrate 403 and the multilayer film body 405 (including thickness and layer, overall refractive index) to the other side (indoor). For example, the angle of penetration of light and the normal can have θ ₃ , so the effect of illumination can be produced.

In another embodiment, when the light source 40 has different incident angles, the design of the surface structure 401 should be modified. For example, if the angle between the side of the surface structure 401 and the normal is θ _{1 of} about 33 to 47 degrees, then θ ₂ is Good about 15 to 25 degrees.

Since the thermal insulating film described in the present disclosure may be disposed outdoors, such as the surface of an exterior window of a building, it may be a passivated structure due to erosion of particles of the outdoor environment over the years, as shown in FIG. 4B. Passivation of the surface structure 401 ', the result of passivation may lead to changes in the characteristics of this surface structure, but according to the experiment, if properly cleaned, or coated or coated with self-cleaning material or functional coating, such as Titanium oxide The titanium dioxide in the middle, or the fine structure, makes it difficult for dust and the like to adhere to the above, and the problem of reduced functionality due to structural fouling passivation can be avoided. Such changes do not cause a substantial change in the optical properties of the surface structure. For example, as shown in Fig. 4B, if the optical characteristics of the surface structure 401' are not greatly affected, the heat-insulating light-guiding film can effectively guide the light into the room by the design of the substrate 403 and the multilayer film body 405.

Next, as shown in FIG. 4C, the heat insulating light guiding film mainly has a surface structure 402 and a multilayer film body 406, which may be disposed on both sides of the substrate 404, and the light source 40 of this example is composed of a multilayer film. The side of the film body 406 is directed toward the heat insulating light guiding film.

The figure shows a normal to the surface of the vertical substrate 404, and the surface structure 402 is sectioned to an approximately triangular geometry, with the normal passing through the vertices of the triangle forming the upper and lower angles, as shown by θ ₁ and θ ₂ . When the light penetrates the multilayer film body 406 and the substrate 404, it is reflected by the side having the angle θ ₁ , and then refracted by the side having the angle θ ₂ to form the light upward.

Through the ray traces depicted in this example, it can be seen that the heat-insulating light-guide film proposed in the present disclosure can effectively guide the incident light to the other side to facilitate the use of illumination.

According to experimental values, the thermally insulating light-guiding film of Figure 4C wherein the preferred geometry in the surface structure is: θ _{1 is} preferably about 25 to 35 degrees, and θ _{2 is} preferably about 1 to 7 degrees.

It should be noted that the structural angles of the above several aspects are changed according to the environment to be set. If the light source is sunlight, it will be changed according to the average position of sunlight incident (such as the earth latitude according to the environment); meeting Because of the optical properties of the material of the surface structure, such as the refractive index; for some purpose, the design of the surface structure will also vary depending on the optical properties produced by the multilayer film structure to which the surface structure is mated.

Further, according to requirements, the surface structure of the heat-insulating light-guiding film described in the present disclosure may have a polygonal shape to form a surface structural feature of a polygonal corner post, as shown in FIGS. 4D and 4E.

4D is a schematic view of the thermal barrier film, wherein the surface structure is a bilaterally asymmetrical polygon, and the light source (reference arrow) is incident from a side having a surface structure through which the design of the structure (including thickness and refractive index) can be Directing the light to the other side, even forming a refracted upward light.

With respect to the embodiment shown in FIG. 4D, the light source of FIG. 4E is first directed to the multilayer film body. Through the design of the multilayer film in the film body, the light can be directed to the other side and refracted through the surface structure to produce the other side upward. Light.

In embodiments of the surface structural layer on the thermally insulating light directing film, the surface structural layer will be designed as desired, with the primary function being to direct light. The microstructure on the surface structure layer can be formed by means of a stencil or a roller embossing, usually a continuously changing structure, in order to produce a stable and uniform refracted ray.

As shown in FIG. 5, one of the surface structure embodiments of the heat-insulating light-guiding film of the present invention is shown in this example. The surface structure 53 shown in this example is a structural feature having a circular arc-like column shape formed on the substrate 51, and is extended to the whole or A columnar structure on the surface of a portion of the substrate 51. The substrate 51 shown here may also be the multilayer film film body described in the above embodiments, and the substrate such as glass is omitted.

Another surface structure embodiment is shown schematically in FIG.

This example shows that the surface structure 63 on the substrate 61 has a circular arc shape, and the structure extending over the entire or partial substrate 63 has a wave. The undulating surface microstructure. In this example, in addition to the one-side section showing an arc shape, the columnar body exhibits a change of high and low undulations, forming a columnar wave pattern. Such a design optically prevents the phenomenon of bright and dark bands caused by interference.

The above embodiments of the surface structure, including the cross-sectional shape and the extended columnar structure, are not intended to limit the microstructure of the present invention applied to the thermal barrier film.

7A and 7B show an embodiment of an apparatus for applying the heat insulating light guiding film of the present invention to a window.

In FIG. 7A, the heat-insulating light-guiding film is disposed on a carrier 70 having a light-transmitting effect, such as an opening for attaching the heat-insulating light-guiding film to the carrier 70 by using a pressure sensitive adhesive (viscosity generated under pressure) or an optical adhesive. For example, on the light-transmissive substrate such as glass, acrylic, etc. of the window.

For example, the carrier 70 is a glass or transparent acryl on the window of the building. The heat insulating light guiding film is disposed on one side of the carrier 70, including the outdoor side or the indoor side. If it is disposed on the indoor side, it can be avoided.

The heat insulating light guiding film is mainly composed of a multilayer film body 705 and a surface structure layer 701, or a substrate 703 may be further provided as a supporting body of the multilayer film body, and the multilayer film body 705 and the surface structure layer 701 are respectively disposed on Both sides of the substrate 703. In this case, the multilayer film body 705 is combined with the carrier 70.

When light is emitted from the side of the carrier 70 (such as outdoors) to the device, the light enters the thermal insulating film through the carrier 70, and is first refracted and interfered by the multilayer film body 705 to block or reflect light in a specific optical band according to requirements. The formation of a specific light band can penetrate the light of the device, including the effects of polarizing, heat insulation and the like. Thereafter, light can enter the surface structure layer 701 via the substrate 703, and the optical properties of the surface structure layer 701 direct the light to the device. One side (such as a room), through the guidance of the surface structure layer 701, can produce specific effects, such as forming a light source for illumination in the room.

The embodiment shown in Fig. 7B in particular attaches the side of the surface structural layer 701 of the thermal barrier film to the carrier 70.

Since the surface structural layer 701 has a surface microstructure, which is not a flat surface, when a colloid such as a pressure sensitive adhesive or an optical glue is used as a connecting means when attached to the surface of the carrier 70, the colloid 707 should fill the microstructure and the carrier. In the gap between the surfaces of 70, and finally a surface structure having a corresponding surface microstructure is formed, in order to avoid that the colloid 707 having the surface structure changes its optical characteristics, a low refractive index glue (707) close to the refractive index of air can be used ( The refractive index is about 1.2~1.4, close to air), such as a fluorine or hydrazine functional base.

According to another embodiment, the gap between the surface structure layer 701 and the carrier 70 may also be filled with a gas having a specific optical characteristic, and the optical characteristics of such a gas include a gas, a liquid or the like which can be filled without changing the optical characteristics of the existing device. The object may also include a gas having an effect of insulating or isolating a specific optical band, such as argon, helium, neon or the like, which has a lower thermal conductivity than air, thereby generating an insulating effect or improving the heat insulating ability. An inert gas or other gas or liquid that can insulate (reflect infrared light) and block ultraviolet rays.

Columnar and triangular columnar structures in a surface structure produce optical properties that are tailored to specific needs, such as the need to meet different incident ray angles. For example, outdoor sunlight has different angles from morning to night. If a mixed surface structure is applied, different angles of incidence at different times may be due to The surface structure is effectively incident into the room.
