Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, for the convenience of explanation, they can be simplified, processed, or omitted. Further, the term "semi-transmissive portion" is not necessarily limited to half of the light transmittance at the light transmittance, but may be within a predetermined range at half the light transmittance. Further, the light transmitting portion is not limited to a transparent one, meaning a complete light transmittance, and can be configured to have a predetermined light transmittance.

FIG. 1 is a perspective view of a billboard according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of a billboard according to an embodiment of the present invention.

A billboard according to an embodiment of the present invention includes a base 100, a transflective part 200 coupled to an edge of the base and having a space therein, a transparent part 300 formed on the transflective part, A diffusion part 400 formed on the upper side of the transparent part, and an LED module 500 mounted on the space part.

The billboard according to the present invention includes a body having various shapes such as a letter, a number, a symbol, and a figure expressing contents to be advertised, and the body is stacked so as to have a visually protruding effect.

The base 100 is formed in a shape having the same shape as letters, numbers, symbols, graphics, and the like. The base is secured to the wall of the facility. For example, in the case of capital letters, it has a plate shape having a predetermined thickness. Hereinafter, capital letters in English will be described as examples.

Acrylic is used as the material of the base. In the present invention, an acrylic resin is used to form the base, but a material having a light transmittance of a predetermined thickness can be used. Here, the predetermined thickness may be a thickness required for fixing to the facility.

A reflector 110 is attached to the upper surface of the base. The reflector reflects light emitted from the LED module in the front direction and the side direction.

The semi-transparent portion 200 has a shape corresponding to the edge shape of the base, and is formed to be larger than the size of the base. A space portion corresponding to the edge shape of the base is formed inside the semi-transparent portion. In the space 210, an LED module for illuminating the billboard is mounted. The space portion is formed to be smaller than the size of the edge shape of the base. In other words, the inside of the transflective portion is in surface contact with the base and the outside of the transflective portion is protruding from the edge of the base.

In the present invention, the transflective portion has a shape protruding from the edge of the base. The size of the outer surface of the transflective portion may be the same as the size of the outer surface of the base, the transparent portion and the diffusion portion.

The transflective portion has a predetermined light transmittance. The semi-transparent part has a predetermined color. Thus, the light emitted from the LED module is transmitted through the semi-transmissive portion, and the light visually recognized outside the semi-transmissive portion emits low-luminance light having a predetermined color.

The transparent portion 300 transmits most of the light emitted from the light source. The light-transmitting portion can be formed of acrylic transparent material. The light-transmitting portion is coupled to the upper side of the transflective portion.

Referring to FIG. 2, when the base to which the reflector is attached, the transflective portion, and the transparent portion are sequentially connected, the space portion of the transflective portion is sealed. An LED module is mounted in the sealed space portion. Specifically, the LED module is mounted on the lower surface of the transparent portion. The light emitted from the LED module is reflected by the reflector attached to the upper portion of the base, and then proceeds toward the translucent portion and the transparent portion.

The diffusing unit 400 diffuses the light reflected from the reflector and transmitted through the light transmitting unit. The diffusing portion has a transmittance with a predetermined ratio. The transmittance of the diffusing portion is formed different from the transmittance of the transflective portion. It is preferable to set the transmittance so as to be visually protruded according to the shape of letters, numbers, symbols, figures and the like.

Further, the color of the diffusing portion may be formed differently from the color having the semi-transmissive property. The person who looks at the billboard feels that the billboard is more protruded from the different colors of the spreading part and the transflective part and has a sense of aesthetics.

Meanwhile, as another embodiment of the present invention, the diffusion portion, the light projecting portion, and the transflective portion may be designed to have different light transmittances. According to this configuration, when the advertisement board is viewed from the front, most of the light is seen in the diffusion portion, and the light shown in the transparent portion and the semi-transparent portion is the light seen in the periphery of the diffusion portion.

Therefore, the diffuse portion is a portion showing the contents of the advertisement, and the light seen in the transparent portion and the semi-transparent portion illuminates the edge of the diffusion portion. The light seen from the transparent portion and the translucent portion can be recognized by distinguishing the region of the diffusion portion, thereby fully recognizing the contents of the advertisement represented by the diffusion portion. That is, by visually designing the diffuser, the light projecting part and the transflective part with different light transmittances, the viewer can clearly recognize the billboard, thereby ensuring visibility.

The LED module 500 generates light. Light emitting diodes (LEDs) are optical devices having low power and high brightness. The LED module includes a light source LED and a case for protecting and fixing the LED. One or more LED modules may be electrically connected to each other depending on the size of the mold. The LED module is attached to the lower surface of the light transmissive portion, and the light emitted from the LED module is reflected from the reflector of the base to the transflective portion, the transparent portion and the diffusion portion.

FIG. 3 is a cross-sectional view of FIG. 2, illustrating the components of the billboard according to an embodiment of the present invention. 4 is a sectional view of a billboard according to an embodiment of the present invention.

Referring to FIG. 1, a reflector, a transflective portion, a transparent portion, and a diffusion portion are sequentially stacked on an upper portion of a base, and LED modules are disposed at regular intervals in a space portion of the transflective portion. Specifically, one or more LED modules, which are light sources, are attached to the lower surface of the transparent portion so as to have a predetermined interval. Here, the thickness of the transflective portion is thicker than the thickness of the LED module.

A predetermined space is provided between the LED of the LED module and the reflector of the base. This space secures an optical path through which the light emitted from the LED can travel in various directions. The light emitted from the LED module is reflected by the reflector attached to the base, and proceeds to the translucent portion, the transparent portion and the diffusion portion.

Here, a sufficient distance must be ensured so that light emitted from the LED module is reflected by the reflector to form an optical path. The thickness ratio of the LED module to the translucent portion is preferably 1: 1.3 to 1.7. Since the spacing distance is related to the direction of the optical path from the light source and the arrangement among the LED modules, the spacing distance should be formed based on the size of the mold.

5 shows an optical path for light from a light source according to an embodiment of the present invention. Referring to the drawings, reference numeral L1 denotes light transmitted through the transflective portion, reference numeral L2 denotes light transmitted through the transparent portion, and reference symbol L3 denotes light transmitted through the transparent portion and the diffusion portion.

The diffusion part of the billboard according to an embodiment of the present invention has a white color and the transflective part has a blue color. When the billboard is viewed in oblique direction, the white diffusing portion is seen on the upper side, and in the transflective portion formed on the base, the light including the blue point light source is emitted and seen. The bass is almost invisible. And the LED light is seen as a point light source in the transparent portion formed on the upper part of the transflective portion.

When a person passing by looks at the billboard, the shape of the white corresponding to the shape is recognized, the point light source is perceived to be prominent around the point, and the light including the point light source and the blue point light source is emitted . Therefore, it is possible to give a protruding effect and aesthetic sense, and it is advantageous that the visibility is clearly recognized.

The colors of the diffusion part and the semi-transparent part according to the present invention are not necessarily limited to white and blue. Various colors can be selected and configured according to the shape to be advertised or the contents thereof.

6 is a view illustrating a method of joining a billboard according to an embodiment of the present invention.

Referring to FIG. 6 (A), the diffusion unit, the light-projecting unit, and the LED module are combined to prepare an upper assembly. Also, a reflector is attached to the upper part of the base, and then the semi-transparent part is joined to prepare the lower part. Then, the upper and lower assemblies are coupled to each other to complete the billboard.

Here, the diffusion unit and the light emitting unit may be first coupled, then the LED module may be coupled, and the diffusion unit may be coupled after the LED module is coupled to the lower surface of the light transmission unit. If a commercially available LED module is used, it can be easily attached since the double-sided adhesive is provided on the back side thereof.

6 (B) is a view showing a billboard according to another embodiment of the present invention and a combining method therefor.

Referring to the drawings, the size of the reflector has a size corresponding to the size of the space portion of the transflective portion. After attaching the semi-transmissive portion to the upper portion of the base, a reflector is separately attached to the region formed inside the semi-transmissive portion.

Of course, the reflector may be attached to the upper portion of the base with priority, and the region where the reflector is formed and the space portion of the transflective portion correspond to each other.

7 is a block diagram illustrating a method of manufacturing a billboard according to an embodiment of the present invention.

A method of manufacturing a billboard according to an embodiment of the present invention includes a first step (S100) of attaching a reflector to an upper part of a base, a second step (S200) of coupling an integrated base and a transflective part to an upper part of the reflector, (S400) of attaching an LED module to a lower surface of the light-transmitting portion, and a fourth step (S400) of attaching an LED module to the lower surface of the light-transmitting portion and the integrated base, the reflector and the transflective portion, And coupling the LED modules to each other (S500).

A first step (S100) of attaching a reflector to the upper part of the base: The base is cut into a shape such as letters, numbers, symbols, graphics, etc., and a reflector is attached to the top of the base. Here, the shape and size of the base may be the same as the shape and size of the reflector, or may be formed to have the same shape and size as the space portion of the transflective portion.

(S200) of coupling the semi-transparent portion to the upper portion of the integrated base and the reflector. The semi-transparent portion having an edge shape of the base and having a space portion is coupled to the upper portion of the integrated base and the reflector. Since the edge region of the base and the inner region of the transflective portion are in surface contact with each other, bonding can be easily performed using an adhesive.

On the other hand, the transflective portion can be first coupled to the top of the base, and then the reflector can be attached to the top of the base.

A third step (S300) of combining the transparent portion and the diffusion portion having the same shape as the base: The transparent portion and the diffusion portion are prepared to have the same shape and size. An adhesive is applied between the prepared transparent portion and the diffusion portion, and they are bonded to overlap each other. Since the transparent portion and the diffusion portion have the same shape and size, alignment for bonding is easy.

Fourth step S400 of attaching the LED module to the lower surface of the light transmitting part: When the light transmitting part and the diffusion part are integrated, one side becomes the upper surface of the diffusion part and the other side becomes the lower surface of the light transmitting part. Here, the lower surface of the diffusion portion and the upper surface of the light transmitting portion are surfaces joined by the adhesive.

Attach the LED module to the lower surface of the light-transmitting part so as to be spaced apart at regular intervals. Since the LED module must be mounted in the space portion of the transflective portion, the area corresponding to the space portion at the edge of the transparent portion should be considered.

Combining the integrated base, reflector and transflective portions with the integrated diffuser, the light projecting portion and the LED module (S500): forming the first, second and the third steps, the base, the reflector and the transflective portion, . In addition, when the third to fourth steps are formed, the diffusion portion, the light-projecting portion, and the LED module are firmly integrated with each other with the adhesive. The two integrated structures are then bonded together by applying an adhesive.

If the base, the transflective portion, the transparent portion, and the diffusion portion of the billboard of the present invention are all made of an acrylic material, their bonding can be achieved by catalyst adhesion. Such a catalyst adhesion is an adhesion method using a capillary phenomenon and is excellent in waterproof performance.

In the present invention, the third to fourth steps are formed after the first to second steps and the fifth step is performed. However, the first to second steps are formed after the third to fourth steps The fifth step can be performed.

According to such a manufacturing method, it is possible to ensure a sufficient separation distance from the reflector of the LED module, and the manufacturing process is simple and the manufacturing time is shortened, so that the manufacturing cost is reduced.

Hereinafter, a method of manufacturing the billboard according to another embodiment of the present invention will be described.

A method of manufacturing a billboard according to another embodiment of the present invention includes the steps of attaching a reflector to an upper portion of a base, and combining a diffusion portion and a light emitting portion, but there is a difference in the step of attaching the LED module.

Specifically, the method includes the steps of: joining the transparent portion and the semi-transparent portion; attaching the LED module to the lower surface of the transparent portion in the transparent portion and the semi-transparent portion that are combined; separating the transparent portion and the semi-transparent portion; And a step of coupling the integrated base, the reflector, and the transflective portion, the integrated diffusion portion, the light projecting portion, and the LED module to each other.

Here, the reason why the joining is performed in the step of joining the transparent portion and the transflective portion is to clearly determine the attachment position of the LED module. When the LED module is directly attached to the bottom portion of the transparent portion, the LED module can be attached to the region where the semi-transparent portion is to be attached when the semi-transparent portion is subsequently coupled, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the present invention is not limited to the disclosed exemplary embodiments, but various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention.
