BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting panel for a building, and more particularly, to a lighting panel used as indoor and outdoor finishing materials, and a lighting panel used for indoor and outdoor wall lighting or floor lighting.

Today, various panel materials are being used as indoor and outdoor finishes for architectural use. Among them, stone, wood, metal materials, synthetic resin materials, or composite materials thereof are used. Traditionally, architectural panels have been emphasized on insulation, soundproofing and safety. However, in recent years, a variety of technologies have been merging with each other, resulting in a tendency to emphasize aesthetic functions. A typical example of such a trend is a lighting panel combined with a lighting and a building panel.

Light panels are known as the simplest type of illumination panels (Prior Art 1). A light guide plate is prepared in a certain frame having a front panel, and an LED lamp is arranged on the side of the light guide plate to complete the lighting device. Generally, according to this conventional technology, it is common to attach a color printout to the front panel in order to implement an aesthetic function. At this time, a grid-like or dot-like pattern is formed on the back surface of the light guide plate at regular intervals in order to transmit light. However, this prior art 1 has a problem that it is not possible to display various textures on the front panel and it is difficult to apply the front panel to various materials such as stone or wood.

There has been an attempt to overcome the disadvantages of the prior art 1 and to provide a lighting function to a panel composed of various materials. One of them is a lighting panel technique in which a hole is drilled in a plate material such as stone or wood, and then an LED lamp is inserted into the hole, or an optical fiber is inserted (Prior art 2). However, in the case of the conventional art 2, if the number of perforations formed on the panel is large and complicated, it is not easy to manufacture and construct.

The present invention has been completed for a long time in order to solve the above problems and the present invention has been completed.

It is an object of the present invention to provide a new architectural lighting panel in which a non-transparent material such as a stone, a wood, a metal material or the like is combined with a light guide plate, and a manufacturing method thereof.

The inventor of the present invention has studied and tried to fabricate an illumination panel by combining a light guide plate with a non-transparent plate-like material such as a stone or wood by combining the above-described conventional technique 1 and the conventional technique 2 described above. That is, a thin non-permeable sheet was formed by forming a pattern and a light guide plate was provided on the back surface. At this time, a grid line and a dot pattern are formed at regular intervals on the opposite side of the side where the non-transmissive thin plate and the light guide plate are in contact with each other. However, the perforated pattern (the first pattern) of the non-tarnish-free thin plate does not coincide with the lattice or the dot pattern (the second pattern) on the opposite side of the light guide plate, so that the amount of light reflected on the perforated portion formed on the non- As a result, a problem was found in which one portion of the first pattern was brighter and the other portion was less bright. Also, when looking at the side view of the non-tarnishing laminate, the light appeared to be faint.

Thus, it was concluded that securing a constant and improved light intensity through the perforated pattern of non-tarnish sheets could be optimized for architectural lighting panels simply because the use of light guide plates on non-tarnish sheets was not sufficient.

On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

In order to achieve the above object, the present invention provides a lighting panel for a building,

According to another preferred embodiment of the present invention, the architectural lighting panel may further include a perforated or etched portion corresponding to the fourth pattern on the surface of the non-tarnish material sheet that does not correspond to the position of the patterned etch portion of the light guide plate.

According to the present invention, not only is it possible to apply finishing materials having various surface textures using a non-tarnish sheet such as a thin stone panel or a wood or metal sheet, It has the advantage of producing good and excellent lighting panels.

In addition, as a finishing material for architectural lighting panels of the present invention, it is advantageous that the finishing material is variously designed according to the shape and material by being installed on the wall or the floor.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing a structural example of a lighting panel for a building according to the present invention; Fig. The architectural lighting panel 1 includes a structure in which the non-tar sheet 200 and the transparent red light guide plate 300 are in contact with each other while being in contact with each other and are coupled to each other with the frame 100.

A non-tarnish material sheet 200 is disposed on a front portion (upper portion in the drawing) of the architectural lighting panel 1 and at least one pattern perforation 210 having a first pattern formed thereon is formed on the non- have. The non-permeable material sheet 200 is punched back and forth (upward and downward in the drawing) through the pattern perforation 210.

The non-permeable sheet 200 is defined as a non-transparent thin plate panel which can not transmit light to natural stones, artificial stones, wood, metallic materials and the like, and can be generally used as a building finishing material. And preferably has a thickness of 1 mm to 5 mm or less. If it is less than 1 mm, it is easy to be used because it is fragile, and if it is larger than 5 mm, the thin plate panel is too heavy to be used as a finishing material. It is more preferable to use a thin plate panel having a thickness of 3 mm or less.

The first pattern forming the pattern perforation 210 may be formed in a portion of the non-permeable sheet 200 as a point, a line, or a plane, and may be formed of any one of letters, numbers, symbols, and graphics. The means for forming the pattern perforations 210 in the non-tarnish material sheet 200 can be processed by a known means such as a CNC, a laser engraving machine, or a sandblasting machine.

A transparent light guide plate 300 made of acrylic or glass is attached to the back of the non-tar sheet 200 (in the drawing, below). A light guide plate 300 having a thickness of preferably 5 mm to 8 mm may be used and may be combined with the non-transparent sheet 200 by an adhesive. The kind of the adhesive may vary depending on the kind of the non-permeable sheet 200 and the intended use. As for the thickness of the light guide plate 300, various standards may be used in accordance with the installation space.

In the present invention, the etching portion 310 along the second pattern is formed on the surface of the light guide plate 300 (the contact surface with the non-tarnish sheet 200). The second pattern of the pattern etching part 310 corresponds to the first pattern of the pattern perforation 210 of the non-tarnish material sheet 200 in a one-to-one correspondence. That is, the etching position of the pattern etching part 310 of the light guide plate 300 is formed to be the same as the opening position of the non-permeable material sheet 200. In other words, the first pattern and the second pattern are the same.

The light guide plate 300 is supported by a support 120 formed of an inner panel of the frame 100. A plurality of LED lamps 10 are arranged in the side part 110 of the frame 100 so that an edge type lighting panel can be formed. The LED lamp 10 may be arranged on one side or both sides of the side portion 110 of the frame 100. Although not shown in the drawings, a power source and a control unit are fixed to the frame 100, Can be supplied and controlled.

The support 120 of the frame 100 may be provided with a water outlet 121 formed of a plurality of holes through which water may be discharged to the outside of the frame. Since the architectural lighting panel 1 of the present invention is installed on the outer wall or the floor of the building, the rainwater penetrates into the frame 100, and guides the water penetrated by the plurality of water discharge ports 121 to be discharged out of the frame. As a result, condensation due to moisture and distortion of illumination can be prevented.

The shape of the frame 100 preferably has a rectangular shape, which is advantageous in constituting the lighting panel module so as to connect a plurality of lighting panels. However, the triangle, the pentagon, the round, the oval, etc. Various geometric shapes can be constructed. The frame 100 of the illustrated embodiment is rectangular in shape and the edge ends of the frame 100 include fastening means 131a and 131b for securing to the wall or floor at the inwardly bent portion extending backward The fixing portions 130a and 130b are provided. The fixing means 131a and 131b may be a screw or a nail that pierces a wall or a floor, or the fixing portions 130a and 130b may be brackets. In addition, the fixing portions 130a and 130b may be provided at opposite ends of the frame 100 in the rectangular shape, and may be provided at the ends of the four sides in other embodiments.

The frame 100 may be made of a metal material such as stainless steel having good durability, or may be made of a plastic having good rigidity. The material of the frame 100 may be deformed by various materials.

2 and 3 show more specifically the relationship between the non-tar sheet 200 and the transparent light guide plate 300 according to the present invention. Fig. 3 shows a cut-away section when the pattern perforations 210 of Fig. 2 are vertically cut.

The first pattern of the pattern perforation 210 of the non-tarnish sheet 200 and the second pattern of the pattern etching part 310 of the light guide plate 300 below the first pattern correspond to each other in a one-to-one correspondence. That is, the surface of the light guide plate 300 under the pattern perforations 210 that penetrate the surface of the non-tar sheet 200 is etched to a predetermined depth.

The etching depth D of the patterning portion 310 of the light guide plate 300 is preferably 50 microns to 1 mm or less. When the thickness is less than 50 microns, the light amount becomes small and it is difficult to exhibit an effective function of the illumination panel. If it is larger than 1 mm, it is necessary to etch the surface of the light guide plate 300 which is fragile as much as it is, so that it is difficult to etch the pattern, resulting in a disadvantage that time and cost are increased.

In the method of manufacturing the architectural lighting panel of the present invention, the connection between the non-tar sheet 200 and the light guide plate 300 can be performed in two ways. In the first bonding method, the non-permeable sheet 200 and the light guide plate 300 are adhered to each other with an adhesive agent, and pattern puncturing (non-permeable sheet ( 200) surface) and pattern etching (the surface of the light guide plate 300). In this case, care must be taken not to damage the light guide plate 300 at the rear (lower) side. Next, a process of perforating the surface of the light guide plate 300 with a pattern (first pattern) prepared in advance on the non-permeable sheet 200 and a process of etching the surface of the light guide plate 300 to a certain depth in the same pattern as the first pattern And the non-tar sheet 200 and the light guide plate 300 are joined to each other to align the pattern perforation 210 and the pattern etcher 310 together. It is advantageous in that it is more accurate and safe because it is processed according to the characteristics of materials and then combined.

When power is applied to the LED lamp 10 in the architectural lighting panel 1 having the non-tarnish sheet 200 and the light guide plate 300 manufactured in this manner, the pattern of the light guide plate 300, which is a transparent material, And the light is emitted to the outside through the pattern perforation 210 of the non-transparent material sheet 200. As a result, That is, in the case of the non-tarnish material sheet 200 such as stone, wood or metal, light is emitted only from a pattern determined by the pattern perforation 210, so that various designed lights are combined with a finish material such as stone, wood, There are advantages to be able to. Various textures and various patterns of illumination are possible.

The lighting panel 1 for construction shown in Fig. 1 is made of one module and can be further strengthened as a construction finishing material by connecting them laterally or by constructing them later. For example, the frame 100 of FIG. 1 may be manufactured to have a size of 400 mm x 400 mm, and a plurality of architectural lighting panels 1 of this standard may be manufactured and connected to each other. In this case, the circuit wiring can be performed so that the configuration of the power source unit connected to the LED lamp is controlled integrally.

≪ Another embodiment of the present invention >

1. A reflective sheet can be attached to the back of the light guide plate 300 so that the light emitted from the LED lamp can be more easily transmitted to the front surface.

2. Fig. 4 proposes another embodiment of the present invention. The structure between the non-tar sheet 200 and the light guide plate 300 is the same as in Figs. However, a plurality of patterned etchings 320 may be provided on the opposite side of the non-tarnish sheet 200 and the light guide plate 300 (i.e., the lower surface in the drawing) with a third pattern of grid pattern or dot pattern have. This is an embodiment in which a known pattern configuration of a light guide plate at the time of manufacturing a light panel is combined with the present invention. Also in such an embodiment, the pattern perforation 210 of the non-permeable sheet 200 and the pattern etch portion 310 of the light guide plate 300 correspond one to one with each other. On the other hand, the pattern etching portion 320 on the lower surface of the light guide plate 300 does not correspond to the pattern perforation 210 of the non-tar sheet 200. That is, the first pattern and the second pattern correspond to each other, but the third pattern does not. Further, in this embodiment, the reflection sheet 400 can be further attached.

3. In the internal structure of the frame 100, the mounting arrangement of the LED lamps 10 may be provided on three or four sides of the frame 100, depending on the size of the frame and the installation environment. That is, the lamp arrangement in which the LED lamps 10 are installed may be installed on one or more sides of the frame 100. In addition, the power supply unit and the control unit may be installed inside the frame according to the quantity, size, and arrangement of the installed frames, or may be installed outside to be electrically connected to the LED lamps 10 inside the frame. Particularly, when the power supply unit and the control unit are provided outside, the frame 100 of the present invention is manufactured as an illumination panel module, and the efficiency of the wiring can be improved when the plurality of the illumination panel modules are aligned.

4. As described above, according to an embodiment of the present invention, the etching depth D of the patterned etching portion 310 of the light guide plate 300 is preferably in the range of 50 microns to 1 mm. In some embodiments, the depth of the patterned etch 310 may be the same. In another preferred embodiment of the present invention, the depth D of the patterned etch 310 may be different. Particularly in the latter embodiment, the depth of the etching can be progressively deeper from near to far away from the light source depending on the distance of the LED lamp 10 from the light source. In this case, it is possible to secure the maximum amount of light, thereby improving the performance of the lighting panel.

5. The technical idea of the present invention is that the pattern perforations 210 of the non-tar sheet 200 and the patterns of the pattern etchers 210 of the light guide plate 300 correspond one to one with each other, (First pattern) of the non-permeable sheet 200 contacting with the viewpoint of the etch pattern (second pattern) of the pattern etch portion 210 formed on the upper (front) surface of the non-tarnish sheet 200 . Therefore, perforation or etching according to the fourth pattern may be added to the surface of the non-tarnish sheet 200 at a position not corresponding to the pattern etching unit 210 of the light guide plate 300. The function of a light panel with a good light quantity can be realized in relation to the first pattern and the second pattern, and the use environment will be mainly night. However, during the day when the LED lamp 10 is turned off due to the presence of the fourth pattern and light is not transmitted to the first pattern of the non-permeable sheet 200 through the light guide plate 300, the fourth non- The pattern can be visually revealed. This makes it possible to construct a finishing material having different patterns of day and night. Preferably, the pattern may be painted in a color different from the surface color of the non-permeable sheet 200 along the fourth pattern.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the present invention is not limited by the modifications or substitutions that are obvious to those skilled in the art.
