Description

Reflecting sheet having an irregular curved surface {Reflecting sheet having distorted surface}

The present invention relates to a reflection plate attached to an advertisement board or a light to cause light reflection, and in particular, the surface is made of irregular curved surface to produce a diffuse reflection effect to minimize the light loss to have a uniform brightness effect.

In general, a billboard or a lighting lamp is equipped with a reflecting plate on the back to maintain the brightness while minimizing the light loss with a limited amount of light to have an efficient lighting effect.

In this case, the reflector is simply formed by painting white or by attaching a reflective sheet made of silver foil. In the conventional reflector, light is constantly reflected only in a predetermined direction so that the reflection width is reduced, so that the light loss occurs. In the case of an advertisement board mounted with a fluorescent lamp, there is a problem that light marks are generated on the advertisement surface, thereby inhibiting the advertisement effect.

In addition, such a reflector is used to illuminate an indirect light on a subject (a person, an object) even when taking an image or a photograph. In this case, sunlight or illumination light, which is a light source, is reflected on the reflector with a straight line, There is a problem with light marks on the subject.

Therefore, in order to offset this, it is necessary to use a reflector after securing a certain distance from the subject. However, when the reflector is far from the subject, it is difficult to give an indirect lighting effect to the target. And there is a problem that must use a plurality of reflectors.

Therefore, when using a reflector of light or a reflector as a photographic accessory, it is used to cause diffuse reflection by wrinkling an aluminum sheet such as foil, but this is not the ultimate solution, especially when the crushed aluminum sheet is pressed or pressed. There is a problem of being restored to a flat state again.

The present invention has been made in order to solve the above-described problems, the surface is made of silver foil embossed irregular curved surface is formed on the surface to cause diffuse reflection action by the curved surface of the surface, such a reflector is thin Although it is made of thin plate, even if a certain pressure is applied, the embossed shape is maintained to maintain the diffuse reflection effect.

In order to achieve the above object, the present invention constitutes a reflective sheet by laminating and laminating a silver deposition film for reflection, a long fiber nonwoven fabric for foam formation, and a shrinkage sheet having a high shrinkage rate, and then the surface of the reflective sheet is formed. After the pattern on the silver deposited film by the Lola process, the foam of the long-fiber nonwoven fabric is expanded by the thermal firing process and the shrinking sheet shrinks to form the embossed silver deposited film with irregular curved surfaces.

In addition, by applying an adhesive to the lower surface of the shrink sheet and the release paper is to be made of a structure capable of bonding the reflective sheet.

As described above, the present invention causes the diffuse reflection effect by the irregular curved surface, so that the lighting effect can be achieved with the minimum light source, which has an energy saving effect, and the advertisement surface is uniformly emitted to enable high quality advertisement, and the reflection plate The shape of the thin plate can be easily attached to the narrow interior space, such as billboards and lighting, and even if the surface is pressed to maintain the state without deformation on the embossed shape.

In addition, since it is heat-fired at a high temperature, the shape does not change even when the temperature inside the light rises, and it is resistant to ultraviolet rays by using a deposition film. It can be.

In addition, since the reflector is supported by a long-fiber nonwoven fabric, it is not easily torn or damaged, and diffuse reflection is generated on the reflector itself so that indirect illumination can be applied to a subject at a close distance without having to use the reflector from a distance when taking images or photographs. Accordingly, the lighting can be efficiently used even with a small amount of light.

Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings. In the following drawings, the same reference numerals are used for the same components.

As shown in FIG. 1, in the present invention, the reflective sheet 10 is formed by laminating a laminate film 11, a long fiber nonwoven fabric 12, and a shrinking sheet 13. The adhesive sheet 20 is formed by applying an adhesive to the lower surface of the adhesive sheet 20 and the release sheet 30 is adhered to the reflective sheet 10 such that the reflective sheet 10 may be adhered thereto.

In this case, the deposition film 11 is to maximize the light reflection when the silver foil having a high reflectance is deposited and the light is irradiated on the upper surface of the reflective sheet (10).

In order to form an emboss on the reflective sheet 10, as shown in FIG. 3, as shown in FIG. 3, the deposition film 11, the long fiber nonwoven fabric 12, and the shrink film 13 are laminated to the reflective sheet. (10) is produced through a process of pressing the embossed pattern 14 on the upper surface of the deposition film 11, and a process of thermoplasticizing the laminated reflective sheet 10, the reflection Embossing is formed such that the upper surface of the reflective sheet 10 has an irregular curved surface in the process of thermally calcining the sheet 10 and cooling the same.

In this case, the shrinkage film 13 has a relatively higher shrinkage rate than that of the evaporation film 11, so that a difference occurs in shrinkage rate during thermoplastic processing, and the shrinkage film 13 is less than the evaporation film 11. The more shrinkage, the crumpled deposition film 11 is laminated with the shrink film 13 is to form a curved surface.

In addition, by laminating the long fiber nonwoven fabric 12 between the deposition film 11 and the shrinkage film 13, the tensile strength of the reflective sheet 10 is improved, and at the same time, between the tissues of the long fiber nonwoven fabric 12. As the bubble layer of the thermal expansion process is rapidly expanded, the deposition film 11 is further protruded to the surface to swell and maximize the formation of the curved surface.

In addition, the air of the long-fiber nonwoven fabric 12 is pressed by pressing an irregular embossed pattern with a constant force on the upper surface of the reflective sheet 10, that is, the upper surface of the deposition film 11, before the thermoplasticizing of the reflective sheet 10. When inflated, it is possible to swell evenly by unit area along the embossed pattern.

When the embossed pattern is pressed (processed) by the reflective sheet 10, the deposition film 11 is enough to be pressed down slightly along the pattern, and the deposition film 11 is not torn or damaged. Compress it on

To this end, in the case of pressing the embossed pattern on the upper surface of the deposition film 11, as shown in FIG. 5, the two rollers 100 and 200 are engaged so that the reflective sheet 10 is inserted therebetween. Irregular uneven surface 110 is formed on the outer wall of the upper roller 100 to compress the reflective sheet 10, and the lower roller 200 is formed of a rubber material to form the uneven surface 110 of the upper roller 100. Even when the reflective sheet 10 is compressed, the reflective sheet 10 is not damaged and only the embossed pattern is taken.

In addition, as a method of forming the uneven surface 110 on the upper roller 100, it is preferable that the outer wall of the upper roller 100 has an irregular shape due to corrosion, but the method of forming the uneven surface 110 is The present invention is not limited to the above-described method, and various known techniques can be used.

In addition, the deposition film 11 and the shrink film 13 are embossed due to a slight shrinkage difference during the thermal firing process. When the shrinkage is excessively different, the embossing is not properly formed and the reflective sheet 10 is torn. Lost or damaged.

Therefore, the deposition film 11 uses a polyethylene terephthalate (PET) film, the shrink sheet 13 is a low density polyethylene (Low Density Poly Ethylene, LDPE) film using a reflective sheet (10) Lamination is desirable to form embossing with moderate shrinkage differences.

Meanwhile, as shown in FIG. 3, when an adhesive is applied to the lower surface of the reflective sheet 10 to form an adhesive surface 20, and the release paper 30 is adhered to the adhesive surface 20, the reflective sheet ( 10) is to be able to be bonded, it is to be able to use the reflective sheet 10 by adhering to the necessary portion after removing the release paper (30).
