Description

Technical Field

[0001] The present invention relates to an optical fiber display device, and more particularly to an optical fiber connection device that can easily connect an optical fiber and a light source, modularize each component, couple them in a sliding manner, and improve the workability of assembly work, and a display device to which the same is applied.

Background Art

[0002] In recent years, fabric lighting devices and display devices using LEDs and optical fibers have been developed.

[0003] The optical fiber is an optical fiber in which a core having a high refractive index is arranged at the center and a cladding having a relatively low refractive index is arranged outside so that total reflection occurs for the light passing through the core.

[0004] Such an optical fiber has the advantages of very little energy loss, a low loss rate of transmitted and received data, and being hardly affected by the outside.

[0005] An optical fiber in which both the core and the cladding are made of a light-transmitting plastic material is called a plastic optical fiber (POF), and the plastic optical fiber is superior in flexibility compared to a general optical fiber made of glass and is resistant to vibration and bending.

[0006] The applicant of the present application has disclosed a display device using an optical fiber and a technique for manufacturing the same in a number of the following Patent Document 1 and Patent Document 2, etc., and has applied for a patent and received registration.

[0007] Patent Document 1 relates to a display device using an optical fiber for transmitting and displaying the screen of a small video device on a large screen.

[0008] Patent Document 2 describes a method for manufacturing an optical fiber display module and a configuration of a manufacturing apparatus, in which a large number of optical fibers are arranged to have a certain area, and a laminate film is coated on the outer surface thereof, so that the light divergence area is widened, breakage is prevented, and durability is improved.

[0009] For example, FIG. 1 is a configuration diagram of an optical fiber display device according to the prior art.

[0010] As shown in FIG. 1, the optical fiber display device 1 according to the prior art includes a large number of optical fiber filaments 3 provided such that an exposed portion 3 is formed on the upper surface of the material, a light source unit 4 that irradiates light or an image at the end of the optical fiber filament 3, and a control unit (not shown) that supplies power to the light source unit 4 and controls on / off operation.

[0011] Each optical fiber filament 3 is individually connected to the light source unit, or is connected to the light source unit 4 via a bundle portion 5 that bundles the rear ends of a plurality of optical fiber filaments 3 as shown in FIG. 1.

[0012] However, even when the light source unit is connected via the bundle portion 5 in the optical fiber display device according to the prior art, the process of individually inserting and connecting each individual optical fiber bundled at the bundle portion into a large number of insertion holes formed in the connector 6 must be performed.

[0013] As described above, the optical fiber display device according to the prior art has a problem that workability is reduced and the labor and cost required for manufacturing work increase because the work of individually inserting and connecting individual optical fibers or an optical fiber bundle into each insertion hole formed in the connector must be performed.

[0014] In addition, the optical fiber display device according to the prior art has a disadvantage that, as each light source and the optical fiber correspond 1:1, in addition to the light irradiated from the light source unit, it is impossible to display a color or a color in which different colors are mixed.

Thereby, the present invention can improve the visual effect and aesthetic feeling by displaying various shapes such as pictures, patterns, characters, etc. in various colors with the optical fiber display.

Modes for Carrying Out the Invention

[0026] Hereinafter, an optical fiber connection device of the present invention and a display device to which the same is applied will be described in detail with reference to the accompanying drawings.

[0027] [First Embodiment] FIG. 2 is a perspective view of a display device to which an optical fiber connection device according to a first embodiment of the present invention is applied, FIG. 3 is an exploded perspective view of the display device in FIG. 2, and FIG. 4 is a cross-sectional view taken along line A-A' in FIG. 2.

[0028] Hereinafter, terms indicating directions such as "left side", "right side", "front", "rear", "upper", and "lower" are defined to indicate the respective directions based on the states shown in the respective drawings.

[0029] In this embodiment, a configuration in which an optical fiber display device 10 is installed along the vertical direction on an installation object 11 arranged along the horizontal direction will be described.

[0030] However, the present invention is not limited to this, and the optical fiber display device 10 may be installed along the left - right direction on the installation object 11 installed along the vertical direction like a flagpole.

[0031] Also, the optical fiber connection device 50 is arranged on one side or both sides of the optical fiber display 30.

[0032] Furthermore, the optical fiber display 30 is not limited to a square shape, and may be formed in a polygonal shape such as a triangle or a pentagon, a circle or an ellipse. On such an optical fiber display 30, various patterns, characters, images, etc. can be configured to emit light in various forms using optical fiber threads.

[0033] Therefore, the optical fiber connection device 50 can be deformed in various ways, not only in a linear bar shape, but also in a shape bent at various angles one or more times or a curved shape.

[0034] As shown in FIGS. 2 to 4, the display device 10 to which the optical fiber connection device of the present invention is applied is installed on the installation object 11 along the horizontal direction, the vertical direction, or a direction inclined at various angles, using an external casing 20 detachably coupled to the installation object 11 in a sliding manner.

[0035] Also, the display device 10 to which the optical fiber connection device of the present invention is applied includes an optical fiber display 30 manufactured using one or more optical fiber threads 31, a light source unit 40 including one or more light sources 42, and an optical fiber connection device 50 that connects the light source unit 40 and the optical fiber display 30 so that the light irradiated from the light source unit 40 is incident on one end of the optical fiber display 30.

[0036] Thus, the display device 10 to which the optical fiber connection device of the present invention is applied further includes a control unit (not shown) that supplies power to the light source unit 40 and controls the driving of each light source 42.

[0037] Inside the outer casing 20, an installation part 21 is provided where an object to be installed 11 such as a support base arranged horizontally is installed. At the lower part of the installation part 21, a coupling part 22 is provided to which a light source part 40 and an optical fiber display 30 connected by an optical fiber connection device 50 are coupled.

[0038] In the center of the installation part 21, an installation space 23 through which the object to be installed 11 penetrates is formed.

[0039] In the coupling part 22, a coupling space 24 is provided to which an optical fiber connection device 50 connecting the light source part 40 and the optical fiber display 30 is coupled. On both sides of the coupling space 24, support parts for supporting the optical fiber connection device 50 are provided.

[0040] For example, the support parts include first to third support parts 25 to 27 that support the lower part, the central part, and the upper part of the optical fiber connection device 50 respectively.

[0041] The first support part 25 is formed in a substantially "┗┛" cross-sectional shape when viewed from the front so as to support the lower end of the optical fiber connection device 50 in a state where the optical fiber connection device 50 is inserted into the coupling space 24, and is provided as a pair of members divided on both the left and right sides.

[0042] The second support part 26 is formed in a substantially "┃┃" cross-sectional shape or a substantially ")( " cross-sectional shape when viewed from the front so as to support both side surfaces of the central part of the optical fiber connection device 50 in a state where the optical fiber connection device 50 is inserted into the coupling space 24, and is provided as a pair of members.

[0043] The third support part 27 is formed in a substantially "┏┓" cross-sectional shape when viewed from the front so as to support the upper end part of the optical fiber connection device 50 in a state where the optical fiber connection device 50 is inserted into the coupling space 24, and is provided as a pair of members divided on both the left and right sides.

[0044] These first to third support portions 25 to 27 are each supported by one or more connecting members extending inside the outer casing 20, and can firmly support the optical fiber connection device 50 connected in a sliding manner through one side of the outer casing 20 by applying pressure from both the left and right sides.

[0045] In this way, the present invention installs a plurality of support portions in the outer casing to firmly support the optical fiber connection device, thereby preventing the optical fiber display from detaching or flowing due to vibrations or impacts applied from the outside.

[0046] The outer casing 20 configured in this way is divided into a plurality of modules having a predetermined width, and one or more modules are continuously arranged side by side to correspond to the horizontal length of the optical fiber display 30.

[0047] For this purpose, a connecting groove (not shown) and a connecting protrusion (not shown) are provided at both ends of each module constituting the outer casing 20 so that they can be connected to each other.

[0048] Such an outer casing 20 is desirably made of a material such as a metal material or a synthetic resin material having excellent heat dissipation performance like aluminum so as to transfer the heat generated by the light source unit 40 and efficiently discharge it to the outside.

[0049] The optical fiber display 30 is manufactured using one or more optical fiber threads 31.

[0050] However, the present invention is not limited to this, and it may be manufactured by a weaving method using a mixture of the optical fiber thread 31 and a general fiber thread 32, or by a non-woven method using a mixture of the optical fiber thread 31 and a material applicable to non-woven fabric.

[0051] An exposed portion is formed in the whole or a part of the optical fiber thread 31 so as to emit light through the outer surface of the optical fiber display 30.

[0052] Therefore, the optical fiber display 30 can emit light through the exposed portions formed on each optical fiber thread 31, and display pictures, patterns, characters, etc. of various shapes.

[0053] Also, as shown in FIGS. 3 and 4, a fixing member 33 for fixing each optical fiber thread 31 and the fiber thread 32 is installed at the upper end of the optical fiber display 30.

[0054] The fixing member 33 is provided with a length corresponding to the upper end of the optical fiber display 30, and fixes the optical fiber thread 31 and the fiber thread 32 extending from the inside to the upper end of the optical fiber display 30 in a sequentially arranged state. And on the upper end of the fixing member 33, a transmission surface or transmission holes for transmitting the light irradiated from the light source unit 30 to each lower optical fiber thread 31 are formed.

[0055] Such a fixing member 33 is manufactured using a synthetic resin material, and the lower part of the fixing member 33 is formed in a cross-sectional shape corresponding to the cross-sectional shape of the first support portion 25 provided on the outer casing 20.

[0056] The upper part of the fixing member 33 is formed in a cross-sectional shape corresponding to the cross-sectional shape of the lower part of the optical fiber connection device 50 in a state of being coupled to the optical fiber connection device 50, so that the fixing member 33 does not separate or flow from the optical fiber connection device 50 due to vibrations or impacts applied from the outside.

[0057] The light source unit 40 includes one or more light sources 42 installed at predetermined intervals on the printed circuit board 41.

[0058] Each light source 42 can be driven by the control signal of the control unit to irradiate lights of different colors. Of course, each light source 42 can also irradiate lights of the same color or change the color of the irradiated light according to the control signal of the control unit. For this purpose, each light source 42 is preferably provided as a multicolor LED.

[0059] In particular, in this embodiment, each light source 42 is provided as a side-view LED that irradiates light through its lower surface when viewed from one side (Figure 3).

[0060] In this way, the present invention applies a side-view LED to the light source unit, minimizes the left-right width of the light source unit, modularizes the light source unit in the form of a printed circuit board, and can be easily assembled into the optical fiber connection device in a sliding manner.

[0061] The optical fiber connection device 50 is formed to extend longitudinally along the longitudinal direction of the installation object 11 so that its cross-section corresponds to the coupling space 24 and is coupled within the coupling space 24 of the external casing 20.

[0062] For example, the cross-section of the optical fiber connection device 50 is formed in a substantially "∩" shape with an open lower surface.

[0063] On the upper part of the optical fiber connection device 50, a light source space 51 for installing the light source unit 40 is provided, and inside the optical fiber connection device 50, at a substantially central part, a lens space 52 for arranging a lens unit 43 that linearly condenses the light irradiated from the light source unit 40 is provided.

[0064] On the lower surface of the optical fiber connection device 50, a fixing space 53 for fixing the upper end of the optical fiber display 30 is formed in communication with the lens space 52 and the light source space 51.

[0065] On the inner surfaces of both side walls 54 of the optical fiber connection device 50, in order to prevent the lens unit 43 arranged in the lens space 52 from shifting, two pairs of fixing ribs 55 project oppositely at the upper and lower ends of the lens space respectively.

[0066] Here, among the two pairs of fixing ribs 55, the pair of fixing ribs 55 arranged at the upper part support the light source unit 40 coupled to the light source space 51 in a sliding manner and function to fix it so as not to flow due to external impact or vibration.

[0067] Of the two pairs of fixed ribs 55, the pair of fixed ribs 55 disposed at the lower part serves to firmly fix the upper end portion of the fixing member 33 of the optical fiber display 30 coupled to the fixed space 53 in a sliding manner by pressing it from both sides.

[0068] Furthermore, at the lower end portions of the inner surfaces of both side surfaces of the optical fiber connection device 50, a pair of fixed protrusions 56 that are coupled to a pair of fixed groove portions 34 respectively formed to be recessed in both side surfaces of the fixing member 33 extend long along the longitudinal direction.

[0069] The optical fiber connection device 50 configured in this way is provided as a module having a predetermined length, and is configured by continuously connecting one or more modules so as to correspond to the horizontal length of the optical fiber display 40.

[0070] The light emitted from each light source 42 is condensed through the lens unit 43, and the condensed light is condensed linearly rather than pointwise so as to enter one end of the optical fiber display 30.

[0071] For this purpose, the lens unit 43 is formed in a bar shape that extends long along the longitudinal direction of the optical fiber connection device 50 instead of a general spherical shape, and one or more are provided for refractive index and light condensation.

[0072] Such a lens unit 43 is manufactured using a material of a transparent material such as a synthetic resin material such as glass, acrylic, or polycarbonate, and can also be formed in a bent shape.

[0073] That is, the lens unit 43 can be changed into various shapes such as an m shape having a convex portion so that light can be irradiated evenly, not only in a bar shape.

[0074] In this way, the present invention can improve the light efficiency by condensing the light irradiated from the light source unit to which the side view LED is applied linearly through the lens unit and making it enter one end of the fabric-shaped optical fiber display.

[0075] In addition, in the process where the light irradiated from each light source is incident on the optical fiber display through the lens unit, the colors irradiated from the light sources adjacent to each other are mixed with each other, so that in addition to the colors irradiated from each light source through the optical fiber display, the mixed colors can be displayed.

[0076] That is, usually, a multicolor LED irradiates three primary colors of red, green, and blue light.

[0077] In contrast, the present invention can adjust the colors irradiated from each light source, the distance between the light sources, etc., mix the three primary colors with each other to display various colors, and can also change the structure in which the optical fiber threads are arranged on the optical fiber display in various ways to impart a three-dimensional sense.

[0078] Thereby, the present invention can improve the visual effect and aesthetic feeling by displaying various shapes such as pictures, patterns, characters, etc. in various colors by means of the optical fiber display.

[0079] Hereinafter, the coupling relationship and operation method of the optical fiber connection device of the present invention and the display device to which this is applied will be described in detail.

[0080] First, the operator slidably couples one end of the printed circuit board 41 of the light source unit 40, the lens unit 43, and the fixing member 33 of the optical fiber display 30 to the light source space 51, the lens space 52, and the fixing space 53 formed inside the optical fiber connection device 50, respectively.

[0081] Then, the light irradiated downward from each light source 42 provided as a side view LED in the light source unit 40 is transmitted to each optical fiber thread 31 applied to the optical fiber display 30 by the lens unit 43 and the fixing member 33.

[0082] Here, as the optical fiber connection device 50, the light source unit 40, and the optical fiber display 30 are each modularized with a predetermined length, a plurality of modules can be connected to each other to configure a length corresponding to a desired length.

[0083] Therefore, in the optical fiber display 30, a fixing member 33 installed at the upper end portion is firmly fixed to the optical fiber connection device 20 by being pressed by both side walls 54 and fixing protrusions 56 of the optical fiber connection device 50.

[0084] Finally, the operator slides and couples the installation object 11 and the optical fiber connection device in which the optical fiber display 30 and the light source unit 40 are coupled to the installation space 23 and the coupling space 24 of the external casing 20, respectively, and then couples a pair of fixing caps (not shown) to the front end and the rear end of the external casing 20, respectively, to finish. For this purpose, each fixing cap is formed in a shape corresponding to the cross-sectional shapes of the front end and the rear end of the external casing 20.

[0085] Then, the control unit supplies power to each light source 42 provided in the light source unit 40 and outputs a control signal for controlling the driving of each light source 42. Here, the control unit can control each light source 42 to light up with the same color as each other or with different colors from each other. And the control unit can also control each light source 42 to change the color of light emission at a predetermined cycle.

[0086] Through the above-described process, the present invention can easily connect the light source unit and the optical fiber display by slidingly coupling the light source unit and the optical fiber display to a space provided in the optical fiber connection device.

[0087] In particular, in the present invention, side-view LEDs are applied to each light source of the light source unit to minimize the lateral width and overall volume of the light source unit, modularize each component, improve the working speed and workability in the assembly operation, and connect the modularized components to each other to correspond to a desired length, so that various characters, images, etc. can be effectively displayed in various lengths and shapes.

[0088] Further, in the present invention, the light emitted from the light source unit is linearly condensed by the lens unit and incident on one end of the fabric-shaped optical fiber display, thereby improving the light efficiency.

[0089] Also, in the present invention, as the light emitted from each light source is mixed with each other in the process of being incident on the optical fiber display through the lens unit, the optical fiber display can display colors mixed with each other in addition to the colors irradiated from each light source. Thereby, the present invention can improve the visual effect and aesthetic feeling by displaying in various colors and various shapes such as pictures, patterns, characters, etc. with the optical fiber display.

[0090] On the other hand, in the above embodiment, it has been described that the optical fiber connection device 50 is directly coupled to the external casing 20 in a sliding manner, but the present invention is not limited thereto.

[0091] [Second Embodiment] FIG. 5 is a perspective view of a display device to which an optical fiber connection device according to a second embodiment of the present invention is applied, and FIG. 6 is a cross-sectional view taken along line A-A' in FIG. 5.

[0092] A display device 10 to which an optical fiber connection device according to a second embodiment of the present invention is applied includes, as shown in FIGS. 5 and 6, an internal casing 60 coupled inside the external casing 20 with an optical fiber connection device 50 coupled therein, similar to the configuration of the display device 10 according to the first embodiment described with reference to FIGS. 2 to 4.

[0093] That is, in this embodiment, the configurations of the optical fiber display 30, the light source unit 40, and the optical fiber connection device 50 are the same as those described in the first embodiment. Therefore, the description will focus on the configurations of the internal casing 60 and the external casing 20.

[0094] The internal casing 60 is formed in a substantially inverted trapezoidal shape or an inverted triangular shape in which the length of the upper surface is longer than that of the lower surface at the end face.

[0095] An insertion space 61 is provided in the internal casing 60 into which the optical fiber connection device 50 is inserted and coupled in a sliding manner. In the lower, central, and upper portions of the insertion space 61, fourth to sixth support portions 62 to 64 having the same structure as the first to third support portions 25 to 27 described in the first embodiment are provided, respectively.

[0096] That is, a pair of fifth support portions 63 for supporting both side walls 54 of the optical fiber connection device 50 are formed to be recessed inward at the central portions of both side surfaces of the internal casing 60.

[0097] The coupling space 24 of the coupling portion 24 provided in the external casing 20 is formed in a shape corresponding to the cross-sectional shape of the internal casing 60.

[0098] For example, the cross-section of the coupling space 24 is formed in a substantially inverted trapezoidal shape or an inverted triangular shape in which the length of the upper surface is longer than that of the lower surface. On both sides of the coupling space 24, a pair of guide protrusions 28 are protruded inward so as to correspond to the shape of the fifth support portion 63. Here, in the external casing 20, extension holes 29 are extended long along the longitudinal direction of the external casing on one or both sides so as to release the heat generated by the light source unit 40 to the outside and enable installation on the wall body or support base of a building.

[0099] Therefore, each fifth support portion 63 of the internal casing 60 is guided by each guide protrusion 28 of the external casing 20 in the process of coupling the internal casing 60 to the inside of the external casing 20 in a sliding manner.

[0100] Thus, the present invention can smoothly couple the internal casing to the external casing in a sliding manner and firmly fix the internal casing so that it does not detach from or flow relative to the external casing when an impact or vibration occurs externally.

[0101] Such an internal casing 60, similar to the external casing 20, is preferably made of a material such as a metal material or a synthetic resin material having excellent heat dissipation performance like aluminum so as to be transmitted with the heat generated in the light source unit 40 and efficiently discharged to the outside.

[0102] The internal casing 60 configured in this way is divided into a plurality of modules having a predetermined width and is configured by arranging one or more modules continuously side by side so as to correspond to the horizontal length of the optical fiber display 30.

[0103] As described above, the present invention can apply either both the external casing and the internal casing or only one of them.

[0104] That is, as described in the first embodiment, the present invention can install the display device 10 using the external casing 20 by directly installing the optical fiber connection device 50 together with the rod-shaped object to be installed on the external casing 20.

[0105] In addition, the present invention can also install the display device 10 by removing the external casing 20 and directly connecting the fifth support portion 63 by using, for example, a string or a ring on the fifth support portion of the internal casing 60 or a protrusion formed on the object to be installed 11 provided as a wall, a ceiling, a support stand, etc.

[0106] As described above, the invention made by the present inventor has been specifically described by the above embodiments. However, it goes without saying that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof.

Industrial Applicability

[0107] The present invention is applicable to a technique of an optical fiber connection device and a display device to which the same is applied, in which one end of a light source unit and an optical fiber display are coupled in a sliding manner in a space provided in the optical fiber connection device, so that the light source unit and the optical fiber display can be easily connected.
