Description

{WINDOWS HAVING LIGHTING DECORATION}

The present invention relates to a window provided with a lighting decoration for emitting light, and more particularly, to a window provided with a lighting decoration for providing a variety of aesthetics that can concentrate attention on a window or a door of a building, .

Conventional windows, doors, and the like are mainly formed by fixing a plate glass to a window frame or a door frame. Some form of glass is transparent or translucent in the same tone as the whole, and some of the shapes are expressed by surface treatment techniques such as engraving, embossing, etc. on the glass to make a change. In addition, in order to give a sense of aesthetics to a door or a window, the beauty has been expressed in various ways such as coloring a window, applying a pattern, or mosaicing a glass installed on a door or a window.

In any form, the window glass of a conventional window or door only had a passive function to simply transmit or block external light, and could not emit any light itself.

Light not only makes it different or luxurious according to its usage, it also gives people the attention because of such a luxurious atmosphere. In addition, windows and doors are installed in places that are often visible to people. Paying attention to these points, it is necessary to positively consider ways to utilize windows or doors as advertising means or display means.

On the other hand, the light guide plate is originally recognized as a major component of a backlight unit for LCD panel or advertising film, and has been used only for such a purpose. When used for this purpose, the light guide plate is positioned behind an object such as an LCD panel or an advertisement film, for example, and irradiates light only toward the object. Therefore, the light guide plate has a structure in which light scattering and reflecting elements such as an ink dot pattern, a V-cut, a hologram pattern, an engraved or projected pattern are formed on one surface thereof, and a reflector is attached to the surface thereof. Furthermore, the most important function of the light guide plate is to have high brightness and uniformity over the entire surface of the light guide plate. The light scattering and reflective elements must be formed in a pattern to achieve optimal brightness uniformity. Thus, it was understood that the light guide plate was placed under the stereotypes and placed behind the object to be surveyed, while hiding its own image, and fulfilling its role if it shone brightly and uniformly. Because of these stereotypes, we did not pay attention to various expressive capabilities that the LGP itself could have. It should be noted that a combination of a light guide plate and a light source set can constitute a device which can function as a light emitting device or a display means using light.

Korean Patent Laid-Open No. 10-1671928 (Announced 2014.11.04) Korean Patent Publication No. 10-2013-0034403 (published on Apr. 05, 2013) Registered Utility Model No. 20-0468500 of Korea Register (Announcement of 2013.08.14)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, windows (hereinafter, referred to as 'light-emitting windows') having a lighting decoration according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view illustrating a light emitting window according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating a light emitting window according to an embodiment of the present invention.

1 and 2, the light-emitting window according to the present invention includes a transparent panel 10 formed of a transparent material so that light can be transmitted therethrough, and an illumination decoration installed on the transparent panel 10. [

The lighting decoration includes a light guide plate 100 attached to a surface of the transparent panel 10 and a light source unit 200 installed on a side surface of the light guide plate 100 to emit light toward the light guide plate 100, And a decorative unit 300 having one end adjacent to the light source unit 200 so as to receive and propagate light emitted from the light source unit 200.

The transparent panel 10 is formed of a transparent material so that light can be transmitted through a window, and provides a basic skeleton of a window or a door. The transparent panel 10 serves as a window when installed on a wall surface of a building, and serves as a door when installed in a passageway connecting a space and a space in a building. As the transparent panel 10, a glass panel, an acrylic panel, or the like may be used.

If necessary, a decorative film having an ornamental pattern may be attached to the surface of the transparent panel 10 facing the surface to which the light guide plate 100 is attached, in order to increase the degree of focus on the window.

Hereinafter, each component will be described in more detail with reference to the drawings.

Referring to FIGS. 1 and 2, the lighting decoration according to the present invention includes a light guide plate 100.

The light guide plate 100 is attached to the surface of the transparent panel 10 so that light can be directly emitted from the front surface of the transparent panel 10 and diffuses the light incident from the light source unit 200, Or may output a light pattern of a predetermined image according to a design of a light scattering pattern formed on one surface thereof, for example, the back surface of the light guide plate 100.

In this manner, a pattern is formed on the light guide plate 100 so that light can be emitted from the front surface of the transparent panel 10. That is, when a pattern is not formed on the light guide plate 100, the amount of light can be decreased as the distance from the light source 200 is increased. Accordingly, when viewed from the outside, the edge portion of the transparent panel 10 is bright, ) May appear dark. In this case, when a predetermined pattern is formed on the light guide plate 100, the light guide plate 100 helps to uniformly illuminate the entire surface of the transparent panel 10.

In other words, when the light scattering pattern is formed entirely on the surface of the light guide plate 100, the entire surface of the light guide plate 100 is entirely emitted. When the light scattering pattern is formed according to a specific design, A predetermined light pattern is output according to the design of the light scattering pattern, so that the light pattern is visually observed outside the transparent panel 10.

Specifically, the light scattering pattern may be an expression of a company name, a phrase, a message for advertising, a representation using a symbol, a figure, various patterns, pictures, photographs, etc. .

Such a light scattering pattern can be formed in various pattern structures by an injection molding method, a laser processing method, an ink printing method, a V-cut processing method, and the like.

In detail, the light guide plate 100 may have a number of minute intaglio angles of a small size formed in a partial region thereof, so that the light guide plate 100 can express a desired pattern in cooperation with a remaining region where the intaglio angles are not formed. At this time, in the first region where the engraved is not engraved, most of it causes total internal reflection, whereas in the second region in which the engraved engraved engages, scattering and diffuse reflection are caused, so that the desired pattern is clear Is expressed.

The ink dot pattern formed by such an ink printing method is opaque per se to block the passage of light, and the V-cut pattern formed by the V-cut processing method is capable of increasing the light incident from the lower surface of the light guide plate to the upper surface When the light guide plate employing the above-described light scattering elements is installed in the window, the view of the window is greatly disturbed by the light guide while the light source is not emitting light. On the other hand, when a small number of minute intaglio elements having a small size that can not be distinguished from the naked eye are employed as the light scattering element, transparency to the outside of the window can be ensured while the light guide plate does not emit light in addition to excellent luminescence characteristics.

The light guide plate 100 may be formed in any shape including a polygon such as a triangle, a rectangle, a hexagon, or the like, or a non-polygonal shape such as a circle, an ellipse, a sector shape,

This is because it is not broken or deformed due to its high mechanical strength, is lightweight, has a strong chemical resistance, is transparent, and has a high visible light transmittance.

If necessary, the light guiding plate 100 may be provided with a protection unit 150 on a second surface opposite to the first surface contacting the transparent panel 10 so as to prevent the light guiding plate 100 from being damaged by an external force.

The protection unit 150 may be a protective panel formed of a glass panel, an acrylic panel, or the like, or a protective film formed of a transparent film, a reflective film, or the like. At this time, the reflective film functions to reflect light traveling to the second surface, which is the back surface of the light guide plate 100, only in the direction of the first surface, that is, the front surface of the light guide plate 100. The reflective film reflects light, Various types of reflection films such as an adhesive reflection type can be used.
