Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a light diffusion panel

The present invention relates to a light diffusion flexible panel having perforations, and more particularly, to a flexible panel capable of providing a high-brightness surface emission effect while using a small number of LED elements.

The light source coupling products used for attaching to existing fashion, clothing auxiliary materials and safety covering products include woven fabrics using optical fibers, products using LED or wires, It is very difficult and expensive to use the material, and it has a disadvantage that it is difficult to apply it to other than the weaving product.

In order to apply organic EL (Organic Electro Luminescence) to coating materials, there have been attempts to attach them to wire type or print type. However, it is difficult to naturally apply to textile products such as limit of applicability and artificial adhesion when attached to textile products.

Therefore, it is simple and cost-effective to use coating materials such as fibers that are similar in material to cloth products such as fashion, safety, etc., and it is possible to attach easily without attaching noise such as high frequency, have.

Among these light source coupling products, the use of a specific light source such as LED is limited due to technical difficulties such as items, IT devices, control units, and batteries, and the difficulty of the process, but with the development of wearable technology Various attempts have been made.

Especially, there are more and more products that use LED light source to mount an IT device driving module on the surface of fashion items and to display light out of plastic and other hard and transparent materials. And there is a limitation in the application to a clothes fabric product in which cloth or leather having a high added value is used because of the constitution device for light diffusion and a sense of heterogeneity of the surface material, or a cloth product for safety.

Korean Patent Registration No. 10-1544311 proposes a light diffusion device using LED and optical fiber to reduce weight and cost without using a heavy light guide plate, reduce the number of LEDs to be used, reduce cost, eliminate excessive glare In the prior art, a pair of protrusions, a box-shaped optical fiber fixing part, and a reflector, a cone-shaped reflector, and a diffusion part, which are protruded so as to be fixed to the LED, can be used. The structure is complicated and the material is not flexible, so that there is a limitation in application to clothes fashion products or safety cover products.

Therefore, according to the present invention, it is possible to overcome the above-mentioned problems of the prior art and to minimize the sense of heterogeneity due to touch, the sense of heterogeneity due to IT products, and the sense of lightness of the light source of clothing fashion products and safety cover products, By providing a light diffusion panel that can emit light with a high brightness even with a small number of LED elements and can consume less energy, it can be applied to clothing fashion products or safety coating products, The present invention is directed to a photovoltaic panel which can be produced by a method as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a light diffusion flexible panel having a perforation of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view showing the structure of a light diffusion flexible panel having a perforation of the present invention, FIG. 2 is a plan view of a light diffusion flexible panel having a perforation of the present invention, Fig. 4 is a plan view of a conventional panel when the panel is lighted. Fig.

As shown in FIG. 1, the light diffusion flexible panel having the perforations of the present invention has a light-

A flexible substrate layer (1); A first metal coating film layer (2) formed on top of said flexible substrate layer; An LED element (3) formed on top of the first metal coating film layer; A transparent synthetic fiber filament layer (4) formed on the LED element; And a second metal coating film layer (5) formed on the transparent synthetic fiber filament layer and having a predetermined pattern of perforations.

The light diffusive flexible panel having the perforations of the present invention has the first metal coating film layer 2 on the lower layer of the LED element 3 and the transparent synthetic fiber filament layer 4 on the upper layer of the LED element 3, A second metal coating film layer 5 having a patterned perforation is formed so that light emitted from the LED element is reflected by the upper and lower metal coating film layers and is scattered by the transparent synthetic fiber filament layer to allow light diffusion .

That is, light is reflected by the metal coating film layers 2 and 5 formed on the upper and lower parts of the LED element 3, and the transparent synthetic fiber filament layer 4 formed on the lower part of the second metal coating film layer 5 So that light 6 scattered through a certain pattern of perforations formed in the second metal coating film layer can be diverted to the outside.

In the present invention, the first metal coating film layer and the second metal coating film layer may be a film on which a metal is deposited on a known synthetic resin film, or a metal coating film of any material may be used as long as it can reflect light .

The transparent synthetic fiber filament layer preferably comprises a transparent synthetic filament of any one of polyester, nylon, polypropylene, and polyethylene. Preferably, the transparent synthetic fiber filament layer is formed of a cotton-like material using a highly transparent material. The transparent synthetic fiber filament layer functions as a filler to protect the LED device and the power supply module and at the same time diffuses the light emitted from the LED element and emits the light to the outside through a perforation of the second metal coating film layer .

In general, since the light emitted from the LED element is strong in directivity, as shown in FIG. 4, a small number of LED elements can not emit light through the whole pattern shape. Therefore, in order to exhibit a certain pattern shape, The light emitted from the LED device is reflected and scattered by the metal coating film layer and the transparent synthetic fiber filament layer in the present invention and can be emitted to the outside with high brightness through various patterns of perforation A sufficient luminance can be obtained even with a small number of LED elements.

In some cases, it may further comprise a flexible substrate layer having a certain pattern of perforations on top of the second metal coating film layer for decorating the outside of the flexible panel of the present invention. Wherein the flexible substrate layer is a woven fabric, nonwoven fabric. Leather, suede, and synthetic resin film material.

The perforation of the second metal coating film layer and the additional flexible substrate layer may be performed by using a metal pressurized pressurized air or a laser processing machine to perforate from 0.1 mm to several centimeters in diameter, , Star, specific shape, and the like, and it is possible to form a discharge port of light to be irradiated by performing a plurality of perforations with a specific design on the surface.

The flexible panel of the present invention having the above-described structure can be driven by mounting a control unit and a battery module on one end of a lead wire connected to the LED device. The back surface of the flexible base material layer 1 can be attached to clothes or the like using a magnet, Bag or the like.
