In addition, Figure 4 is a cross-sectional view showing a state in which the decorative block of the present invention is constructed on the building wall.

As shown in Figures 1 to 4, the decorative block 100 according to the present invention is installed as a decorative finishing material on the outer wall surface of the building, the decorative line 112 forming a letter or pattern of a predetermined shape on the outer surface is The optical fiber 120 is installed along the main body 110 and the decorative line 112 formed on the main body 110 and is illuminated by receiving light from an external light generating means, and the optical fiber 120 is the decorative line. It is configured to include a fixing means for fixing on (112).

The block body 110 is a stone having a beautiful surface texture, such as granite, marble, etc., which are generally used as a decorative finishing material of a building.

The decoration line 112 formed in the main body 110 includes a plurality of holes 111 perforated on the main body 110 for insertion of the optical fiber 120. That is, the main body 110 is formed with a plurality of holes 111 perforated through the main body 110 so that the front end portion 121 of the optical fiber 120 can be inserted. The holes 111 form a decoration line 112 such as a character or a character pattern.

In this case, the perforation work for forming the hole 111 may be performed through a perforation means such as a drilling machine or a water jet.

In addition, the present invention may form a decorative line such as a character or a character pattern by digging a certain depth groove in an intaglio form so that the optical fiber is embedded in the surface of the main body 110 of the block 100. However, in this case, since light must penetrate a part of the main body, it is preferable to apply artificial stone or the like of the transparent material as the main body of the block.

The optical fiber 120 is fixed through the fixing means in the state that the front end portion 121 is inserted into the hole 111 formed in the main body 110, the rear end 122 of the optical fiber 120 is installed in the building It is connected to the dimmer 130 which is a light generating means.

The optical fiber 120 employs a plastic optical fiber (POF) made of a relatively flexible synthetic resin material.

The dimmer 130 has a function of providing light (light) to the optical fiber 120 and controlling the illuminance of the light emitted from the optical fiber 120.

The dimmer 130 includes a power supply for supplying power, a switch for opening and closing the power, a light emitting device for generating a light source (light), and an adjustment of illuminance (brightness) of the light source using a metal resistance therein. Means are provided. In this case, the light emitting device supplies the generated light source to the optical fiber 120 to induce illumination by the optical fiber 120.

By providing a light source to the optical fiber 120 through the dimmer 130 having such a configuration is to adjust the illuminance of the light emitted from the optical fiber 120.

The current used in the dimmer 130 is an AC power source (AC 220V), and may be adjusted to various light intensities such as 60W, 70W, 100W, 120W, and thus may exhibit various clarities.

On the other hand, the front end portion 121 of the optical fiber 120 is fixed through the fixing means in the state inserted into the hole 111 of the main body 110.

The fixing means is composed of a primer waterproof layer 113, an epoxy waterproof layer 115, and an epoxy fixing layer 114.

The primer waterproof layer 113 is a waterproof layer in which a primer is applied to a predetermined thickness on the inner circumferential surface of the hole 111 and simultaneously serves as an adhesive and a waterproofing agent.

The epoxy waterproof layer 115 is a waterproof layer filled in a space between the outer circumferential surface of the distal end 121 of the optical fiber 120 and the inner circumferential surface of the primer waterproof layer 113. The epoxy waterproof layer 115 is formed of a material mixed with stone powder and an epoxy resin to form a hole 111. Performs reinforcement and waterproof functions.

The epoxy fixing layer 114 is an epoxy resin layer applied around the rear side of the hole 111 into which the optical fiber 120 is inserted, and abuts with the optical fiber 120, the primer waterproof layer 113, and the epoxy waterproof layer 115 simultaneously. It is in contact with, and is responsible for fixing the optical fiber 120 so as not to be separated from the hole 111 of the main body 110.

When the optical fiber 120 of the present invention is installed in the block 100, a hole 111 for installing the optical fiber 120 is formed in the main body 110 using a punching means such as a drilling machine, and the perforated hole. After applying a primer to the 111 and the front end portion 121 of the optical fiber 120 is inserted, the epoxy resin mixed with stone powder is filled into the hole 111 and cured for a predetermined time, and then the The back part is fixed with clear epoxy. At this time, the front end portion of the primer waterproof layer 113 and the epoxy waterproof layer 115 in the cured state by polishing the surface of the primer through a predetermined abrasive material such as sand paper and planarized, and then performing a polishing operation to finish do.

When constructing the decorative block 100 of the present invention manufactured by the above-described method on the outer wall of the building, the fixed frame 161 is coupled to the connection portion connecting the upper and lower blocks 100, and the fixed frame ( 161 to the front of the concrete wall 200 of the building in the state of the "L" shaped angle (150) supported by the bolt 151 to the end of the butt to fasten by fastening the butt with the bolt 160. do.

At this time, the optical fiber 120 fixed to the block 100 is a bundle in the form of a bundle on the rear side of the main body 110 to form a through-hole 202 formed in the building wall 200 in the state inserted into the flexible pipe 124. Through the interior of the building is connected to the dimmer 130. In this way, by using the dimmer 130 to supply a light source to the front end portion 121 of the optical fiber 120 in front of the decorative block 100 can produce a delicate and colorful lighting effect by the optical fiber 120.

As described above, the optical fiber is embedded in the finishing stone, such as granite and marble, which are used as finishing materials for the interior and exterior walls of the building, in the form of letters or character patterns, so that during a bright day, the beauty of the building itself is not compromised. It can take advantage of the natural materials of high-quality natural beauty of marble or granite, and in the dark night, the lighting effect of the optical fiber 120 can be enhanced to enhance the interior effect of the interior of the building, and more beautifully illuminate the exterior of the building. .

Such interior effects and effects can be implemented on the floor, but will be described below.

5 is a side view schematically showing a decorative block in which an optical fiber is installed according to another embodiment of the present invention. 6 shows another embodiment of the present invention.

The decorative block in which the optical fiber is installed in FIG. 5 has a main body 210 having a decorative line 212 having a predetermined letter or pattern on its outer surface, and a front end portion 221 along a decorative line 212 of the main body. Arranged and fixed at intervals, a plurality of optical fibers 220 are illuminated by receiving light from an external light generating means, fixing means for fixing the front end portion 221 of the optical fiber on the decorative line (212) and It includes a fixing box 240 is fastened to the main body and embedded in the bottom in a state including the optical fiber and the fixing means inside.

The main body 210 may be generally a stone having a beautiful surface texture, such as granite, marble, etc. In addition, various materials such as fomex or artificial stone may be applied. Since each material is formed thin or formum material is vulnerable to pressure, protection means such as tempered glass to protect the main body should be provided.

The body of FIG. 5 is thicker than the body of FIG. 6 in order to configure the body of stone such as granite, marble, and artificial stone. In the case of stone, if it is configured as thin as Pomex, there is a possibility that it may be damaged even in the minute impact, and thus has a large thickness as compared to Pomex.

The decoration line 212 formed in the main body 210 is formed of a plurality of holes (same as 111 in FIG. 3) perforated on the main body 210 for the insertion of the optical fiber 220. same.

Since the optical fiber 220 and the dimmer which is a light generating means are also the same as described above, detailed description thereof will be omitted. However, the light generating means may be an LED module 230 instead of the dimmer, wherein the LED module 230 is a base member 231, a plurality of LEDs 233 is provided, as shown in FIG. A condensing lens 235 disposed on the front surface, a tubular cap 237 covering each of the condensing lenses, and one end of which is connected to a part of the rear end of the optical fiber 220, and the other end of which is connected to the cap 237. 239.

The base member 231 is made of a member such as a PCB substrate and is provided with two or more LEDs 233. The base member may be equipped with a controller for controlling the operation of the LED, a power supply unit (SMPS) 290 for supplying power, or a battery 280. Of course, the power supply and the battery may not be installed in the base member but may be installed in various positions inside the cabinet.

The condenser lens 235 is a lens for collecting light emitted from the LED 233 into one place.

The cap 237 is a tube which covers each condensing lens. Since the condenser lens is arranged for each LED, the cap is also arranged for each LED. The cap can also serve as the housing of the condenser lens. In addition, the cap keeps the distance between the connecting pipe and the condenser lens constant so that the light emitted from the LED can be efficiently introduced into the optical fiber. In order to maintain a constant distance between the connection pipe and the condenser lens, a guide portion such as a protrusion may be formed on the inner surface of the cap to prevent the connection pipe inserted into the cap from being inserted more than a predetermined depth.

The connecting pipe 239 has one end connected to the rear end of a part of the optical fiber. The optical fibers connected to the connecting pipes are bundled. The other end opposite to one end connected to the rear end of the optical fiber is inserted into the cap 237. As a result, the light emitted from the LED and collected through the condenser lens is introduced into the bundle-shaped optical fiber.

According to the above configuration, since the optical fiber is divided for each LED, it is possible to derive a beautiful lighting effect by controlling the driving of the LED in various ways. For example, if there are four LEDs and the color emitted from each LED is different, colorful production is possible as shown in FIG. 9. In addition, when a part of the LED is turned on through the controller, other LEDs are turned off, so that flickering or animation can be produced.

In addition, the use of the LED module eliminates the need for a wheel equipped with various color papers and a motor to rotate the wheel as in a general dimmer, thereby improving productivity and miniaturization.

The fixing means is composed of a primer waterproof layer 113, an epoxy waterproof layer 115 and an epoxy fixing layer 114 as described above, or as shown in Figure 10 epoxy waterproof layer 215, epoxy fixing layer 214 and the waterproof liquid layer 216 can be made. The epoxy waterproof layer 215 and the epoxy pinned layer 214 are the same as the configuration described in FIG. That is, the epoxy waterproof layer is filled between the hole 211 perforated in the main body and the optical fiber in the inserted state, and the epoxy fixing layer is applied around the rear side of the hole in which the optical fiber is inserted to fix the optical fiber to the main body. In consideration of the fact that it is installed on the floor, it is less likely to damage the optical fiber due to the collision or friction with the holes punched on the body than the wall type. Form a waterproofing liquid layer that more reliably prevents the ingress of moisture. The waterproofing liquid layer 216 is formed by applying the waterproofing liquid to the surroundings including the epoxy fixing layer. The waterproofing layer prevents moisture from entering into the minute gap between the epoxy fixing layer and the main body.

Fixture box 240 protects the optical fiber and the LED module present in the rear of the main body. Due to the nature of the decorative block installed on the floor, the front of the main body is formed on the guide line is exposed on the bottom surface and the rear of the main body is recessed in the ground. At the rear of the main body, the rear end of the optical fiber and the LED module are arranged, but if it is buried in the ground without any protection means, it is likely to be damaged. Therefore, a facility box that is fastened to the main body at the rear of the main body is required for the protection of the optical fiber, the LED module, and the like and the easy installation of the decorative block. Naturally, an optical fiber, an LED module, etc. are arrange | positioned inside a cabinet.

In the fixture, a battery 280 for supplying power to the LED module may be further disposed. If there is no battery, power must be supplied from the outside. For this purpose, a through hole 241 through which an external power line connected to the LED module is inserted is formed.

The front of the body should be visible on the floor for illumination. If no means exists, the optical fiber may be damaged by the foreign matter introduced into the optical fiber inserted into the hole formed along the decorative line or the impact applied to the floor. The material of the body also becomes difficult to use soft materials such as pomex. Therefore, it is preferable that the tempered glass 250 is installed in front of the main body as a protection means of the main body and the optical fiber.

Tempered glass is a safety glass reinforced by compressing the surface and tensioning the inside, and has excellent impact resistance. When the tempered glass is installed in front of the main body, since the tempered glass receives the impact applied to the floor, the main body and the optical fiber located behind the tempered glass are protected. In addition, when the tempered glass is installed without being in close contact with the main body, the illuminance sensor 260, the solar cell 270, and the light diffusion PC may be disposed between the tempered glass and the main body.

The illuminance sensor 260 is a semiconductor photo sensor using a photo conductive effect in which a resistance value decreases when exposed to light. The illuminance sensor 260 may determine the blinking / lighting or illuminance of the LED in the LED module using the output signal. If the illuminance sensor is disposed between the tempered glass and the main body and the output terminal is connected to the LED module, the operation of the LED may be determined according to the intensity of light flowing from the outside through the tempered glass. For example, you can flash the LED during the day when bright light enters and turn it on in the dark night. The illuminance sensor is particularly useful for application to standalone decorative blocks that are not powered and controlled from the outside by the LEDs.

In the case of the stand-alone decorative block, a battery 280 for driving an LED light is included, and the battery should be easily charged. The solar cell 270 may be used to easily and effectively charge the battery.

The solar cell 270 refers to a device capable of converting solar energy into electrical energy. When such a solar cell is disposed between the main body and the tempered glass, the solar cell is used to absorb the sunlight. The battery can be charged. Of course, the output terminal of the cell would have to be connected to the battery. If necessary, a power supply can be interposed to convert the power output from the cell to suit the battery.

Tempered glass 250 may be installed in front of the body through a variety of ways. For example, the shock absorbing material 310 such as rubber may be installed at the edge of the main body 210, and the tempered glass 250 may be installed on the shock absorbing material 310.

Meanwhile, the pressure applied to the tempered glass is transmitted to the main body 210 and the installation box 240 fastened to the main body via the shock absorber 310, which may be difficult to construct the installation box to withstand the pressure. When mounted on the floor, pressure may be imposed by humans or vehicles, and the construction of equipment to withstand these pressures requires a material of considerable thickness with high impact resistance. Forming the entire cabinet with these thicknesses and materials will increase weight and cost.

Therefore, when it is necessary to withstand high pressure, a separate pedestal 340 can be used. The pedestal 340 is formed in the form of a column or a wall for transmitting the pressure applied from the outside to the ground and may be installed along the outer circumference of the equipment box so as not to limit the buried space of the equipment box. 5 and 6 illustrate the form in which the pedestal receives the pressure from the main body. Alternatively, the pedestal may be configured to receive the pressure from the tempered glass. In the former case, the shock absorber 310 and the gasket 320 for waterproofing may be stacked between the pedestal and the main body. As described above, the pedestal 340, the shock absorber 310, the gasket 320, the main body 210, the shock absorber 310, and the tempered glass 250 are sequentially stacked to maintain / protect / decorate the stacked structure. Moldings 330 may be installed at the lamination site.

7 illustrates a front surface of the decorative block on which the optical fiber formed according to the above-described configuration is installed.

Looking at the molding 350 is formed along the outer periphery of the body in the center of the flooring (390). The solar cell 270 is disposed inside the molding 350, and the optical fiber 220 is disposed in accordance with the guideline inside the solar cell.

In addition, LED illumination other than an optical fiber can also be added. For LED lighting, a light diffusion PC (Polycarbonate) can be placed behind the part (excess part) of the tempered glass except for a part corresponding to the guideline, and an LED can be arranged behind the light diffusion PC.

Light diffusion PC is a principle that adds opaque light diffusion material (mostly mirror pieces) to polycarbonate resin and then diffuses and reflects light. However, light-diffusing materials scatter light and do not transmit, blocking 50% of light from the light source. Thus, obscuring the guidelines with a light diffusing PC limits the light emitted from the optical fiber placed along the guidelines. In order to prevent such a phenomenon, the light diffusion PC is disposed in the surplus portion. Depending on the size of the tempered glass and the main body, the excess portion may be included in the range of the main body and may be beyond the main body. The light diffusing PC of the surplus portion included in the range of the main body may be disposed between the main body and the tempered glass. In this case, if it is difficult to install the LED between the light diffusing PC and the main body, the LED is installed in the fixture and corresponding to the surplus portion of the main body. By cutting a portion, the light emitted from the LED is emitted to the outside through the light diffusion PC.

11 is a schematic diagram showing a configuration in which a light diffusing PC 350 is added to a decorative block provided with an optical fiber according to the present invention. In the example of FIG. 11, the main body is fastened to the cylindrical box 240, and the light-diffusion PC is arrange | positioned in the surplus part beyond the range of the main body. Since the outer periphery of the surplus portion is also circular, the surplus portion on which the light diffusion PC is to be placed has an overall donut shape with the main body in the center. The light diffusion PC 350 is disposed in the surplus portion formed as described above, and the LED 360 is disposed behind the light diffusion PC 350. In this configuration, the bicycle-shaped guide line formed on the main body is illuminated by light emitted from the optical fiber, and the surplus portion is illuminated by light emitted from the light diffusion PC. In the case of the light diffusing PC, the LED disposed in the rear of the light diffusion PC is installed in the exterior of the installation box 240, and the installation is made in the interior of the installation box when the size of the outer periphery of the installation box. In either case, the LEDs placed behind the light diffusing PC can be powered from a battery or external power wiring installed in the cabinet. It can also be controlled by a controller in the equipment box.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
