DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a traffic signboard according to the present invention having the above-described problems, solutions and effects will be described in detail with reference to the accompanying drawings.

It is to be understood that the terminology or words used herein are not to be construed in an ordinary sense or a dictionary, and that the inventor can properly define the concept of a term to describe its invention in the best possible way And should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention.

1 is an assembled perspective view of a traffic signboard according to the present invention. 1, a traffic signboard according to the present invention includes a case 10, a display plate 30 attached to the front surface of the case 10 in the receiving space, A light emitting plate (indicated by 20 in FIG. 2) attached to the rear surface of the case 10 and a fixing table (not shown) for fixing the light emitting plate 20 and supporting the display plate 30 40).

The case 10 may have a polygonal shape or a circular shape including a quadrangle, as viewed from the front, as long as the case 10 has a structure having an interior accommodating space for accommodating the light emitting plate 20, the display plate 30, And may be formed in various shapes. However, the case 10 has a structure in which the front surface is opened to display traffic display information through the display panel 30. That is, an opening portion (denoted by 13a in Fig. 2) is formed on the front surface.

The light emitting plate 20 and the display plate 30 are attached to the inner space of the case 10 so that the light emitting plate 20 is attached to the rear surface of the inner space of the case 10, 30 are attached to the front surface in the inner space of the case 10. The fixing table 40 fixes adjacent portions of a plurality of light emitting module plates 20a constituting the light emitting panel 20 to be described later and supports the back surface of the display panel 30. [

The light emitting panel 20 is formed by arranging the plurality of light emitting module modules 20a in the lateral and longitudinal directions and is attached to the rear surface of the inside of the case 10, Direction). Therefore, as will be described later, the light emitting plate 20 includes an LED for generating and emitting light.

As shown in FIG. 2, the light emitting plate 20 includes a plurality of light emitting module plates 20a arranged adjacently in the lateral and longitudinal directions. Since the light emitting module plate 20a is formed in a standardized size, the light emitting module plates 20a are disposed adjacent to each other in the lateral and longitudinal directions, thereby making it possible to manufacture a large size traffic display panel of a specific size.

The light emitting module plate 20a is attached to the rear surface of the inner space of the case 10 using an adhesive or the like. However, adjacent portions of the adjacent light emitting module plates 20a may be weakened in adhesion. Therefore, adjacent portions of the light emitting module plates 20a are fixed by the fixing table 40. [

2, in order to fix the edge portions of the adjoining light emitting module plates 20a, the fixing plate 40 is in contact with the adjacent portions of the light emitting module plates 20a, (20). It is preferable that the fixing table 40 is disposed only in the transverse direction or the longitudinal direction of the light emitting plate 20. The reason for this is to minimize the portion where the light emitted from the light emitting plate 20 is not transmitted and to prevent a shadow from being generated.

The fixing table 40 is disposed to support the rear surface of the display plate 30 while fixing the adjacent portions of the light emitting module plates 20a constituting the light emitting plate 20 as described above. In addition, the fixing table 40 minimizes the blocking of the light radiated from the light emitting plate 20 and transmitted through the display plate 30, minimizes the occurrence of shadows on the display plate 30, And is structured to maximize light scattering in a space between the plate (20) and the display plate (30).

Specifically, as shown in FIG. 2, the fixing table 40 has a "C" shape when viewed from the side. Specifically, the fixing table 40 has a structure in which a front surface (a surface shown in FIG. 2) and a both side surfaces (surfaces connected at right angles at both ends of the front surface) are opened in a rectangular parallelepiped shape in which the hollow is hollow. Therefore, the fixing table 40 forms the internal space 47.

In order to form such a structure, the fixing table 40 includes a lower plate 41 which is disposed in contact with an adjacent portion of the light emitting module plates 20a and a lower plate 41 which faces the lower plate 41 to contact the display plate 30 And a vertical plate 45 connecting one side of the upper plate 43 and one side of the lower plate 41 to each other.

The lower plate 41 and the upper plate 43 of the fixing table are arranged to face each other and have a long bar shape. That is, the lower plate 41 has an elongated bar shape so as to be disposed in contact with only the contact portions of the light emitting module plates 20a, and the upper plate 43 is also in contact with the display plate 30 Shaped bar shape in order to minimize the size of the bar.

In order to connect and fix the lower plate 41 and the upper plate 43 of the fixing table, the vertical plate 45 is disposed between one long side of the two long sides of the lower plate 41 and two long sides of the upper plate 43 Connect one long side to the other. As a result, the vertical plate 45 connects only one side of the lower plate 41 and the upper plate 43 with each other. Therefore, the surface of the fixing table 40 facing the vertical plate 45 is opened, and the inner space 47 is formed.

The reason why the vertical plate 45 of the fixing table 40 is connected to only one side of the upper plate and the lower plate as described above is that the light enters the inner space 47 of the fixing table 40 to increase the scattering effect to be. Therefore, the light between the light emitting plate 20 and the display plate 30 can maximize the scattering effect.

The lower plate 41 and the upper plate 43 of the fixing table constituting the fixing table 40 are elongated and contact with adjacent portions of the light emitting module plates 20a, It is possible to minimize the portion that can not be transmitted through the display panel 30 and minimize the generation of shadows. Although both sides of the upper plate and the lower plate of the fixing table 40 shown in Fig. 2 are shown to be smaller than those of the longer side, both sides of the upper plate and the lower plate of the fixing table 40 are much smaller . That is, the lower plate and the upper plate have a long and narrow rod shape.

It is preferable that the fixing table 40 is formed of a material capable of transmitting light while ensuring strength. That is, the fixing table 40 may be formed using polycarbonate or other synthetic resin.

The fixing table 40 is equally applied to the first embodiment of the present invention shown in FIG. 2 and the traffic display panel according to the second embodiment shown in FIG.

The display panel 30 is attached to the front surface of the case 10 in the interior space. Then, light emitted from the light emitting plate 20 is transmitted to display predetermined traffic display information. That is, the light is generated on the traffic signboard and the predetermined traffic sign information is displayed to the driver.

As described above, the traffic display panel includes the light emitting panel 20 disposed on the rear surface of the case 10, the display panel 30 on the front surface of the case 10, The light emitted from the light emitting plate 20 is incident on and diffused from the display plate 30 by arranging the light emitting plate 20 and the display plate 30 at a predetermined interval, So that more light is transmitted through the portion indicating the predetermined traffic display information, so that the traffic display information can be recognized from the outside.

The traffic sign board according to the present invention can be formed in various structures. FIG. 2 is an exploded perspective view of the traffic sign board according to the first embodiment of the present invention.

As shown in FIG. 2, the traffic sign panel according to the first embodiment of the present invention may be configured such that the case 10 is vertically separated. 2, the case 10 includes a base plate 11 constituting the rear surface 11 of the case, a cover 13 constituting the front surface 13 and the side surface 15 of the case 10 17).

The base plate 11 and the lid 17 are separated in order to attach and dispose the light emitting plate 20 and the display plate 30 to the inside accommodation space, but the light emitting plate 20 and the display plate 30 are attached They are combined with each other by various methods. Various methods such as soldering, clips, hooks, screws, and bolts can be used for the bonding method.

2, the base plate 11 constituting the case 10 includes a rear outer portion 31 of the display plate 30 (a front outer portion 31 of the display plate 30 shown in Fig. 2) And a support portion 11b protruding in the front direction of the case along the rim 11a for contacting and supporting the outer side portion of the opposite side of the case 11b.

A light emitting plate 20 having the plurality of light emitting module plates 20a disposed adjacent to each other in the lateral and longitudinal directions is seated in a portion defined by the support portions 11b. That is, the light emitting plate 20 is attached to the surface of the base plate 11 partitioned by the support portions 11b.

As described above, the rear surface portion of the display plate 30 is seated and supported on the supporting portion 11b formed on the rim 11a of the base plate 11, and the light emitting plate 20 is supported on the supporting portion 11b The light emitting plate 20 and the display plate 30 are disposed apart from each other because they are in contact with the surface of the base plate 11 which is partitioned.

At this time, since the traffic signboard according to the present invention has a large size, the display board 30 also has a large size. In this case, the central portion of the display plate 30 may be sagged, and sloshing may occur. Therefore, as described above, the upper end 41b of the fixing and supporting plate 41 constituting the fixing table 40 is configured to support the back surface of the display plate 30. [

It is preferable that the fixing table 40 is disposed in contact with an adjacent portion of the light emitting module plate 20a constituting the light emitting plate 20 only in the lateral direction or in the longitudinal direction of the light emitting plate 20 Do. In Fig. 2, it is exemplified that they are arranged only in the horizontal direction.

The display plate 30 supported by the support portion 11b formed on the base plate 11 is fixed by a lid 17 constituting the case 10. [

The front surface 13 of the lid 17 has an opening 13a for exposing the front surface of the display plate 30 to the outside and a front surface 13a for separating the opening 13a from the front surface of the display plate 30 31). That is, the front surface 13 of the lid 17 is formed by removing only the outer portion of the plate having the predetermined shape, and the removed portion corresponds to the opening portion 13a, (13b).

The front surface 13 of the lid 17 is integrally connected to the side surface 15 of the lid 17. [ Specifically, the side surface 15 is connected along the edge of the frame portion 13b constituting the front surface of the lid 17. That is, the side surface 15 of the cover is integrally connected to the frame portion 13b, and is fixed to the base plate 11 in a state where the supporting portions 11b and the side surfaces of the display plate 30 are piled up.

The side surface 15 of the lid 17 is fixed to the base plate 11 so that the frame portion 13b constituting the front surface 13 of the lid 17 is fixed to the front outer portion So that the display plate 30 can be kept fixedly attached to the front surface of the inner space of the case 10.

It is possible to prevent damage to the front outer portion 31 of the display plate 30 or to prevent the front outer portion 31 of the display plate 30 from being damaged, A rubber packing, an O-ring, or the like can be interposed between the upper and lower portions 13b.

As shown in FIG. 2, the traffic signboard according to the first embodiment of the present invention may have a rectangular shape when viewed from the front, but may have a circular shape. It is preferable that the case 10, the light emitting plate 20 and the display plate 30 have a circular shape when the shape of the traffic sign is circular, and the support 10 formed on the circular base plate 11 11b are also formed along the rim of the circular base plate 11, they preferably have a circular shape.

3 is a perspective view of a traffic signboard according to a second embodiment of the present invention. The traffic sign panel shown in FIG. 3 is different from the traffic sign panel shown in FIG. 2 in that the display panel 30 can be inserted and removed through a side surface. 3 (a) is an exploded perspective view showing the fastening structure of the traffic signboard according to the second embodiment, and FIG. 3 (b) is a perspective view for explaining the internal structure of the traffic signboard according to the second embodiment .

The traffic sign board according to the second embodiment of the present invention is also constituted by a case 10, a light emitting board 20, a display board 30 and a fixing board 40, as in the first embodiment. However, it differs in that one side surface is made openable and the display panel 30 is slid through the opened side surface and is coupled to the entire inner space of the case 10.

That is, the case 10 of the traffic signboard according to the second embodiment of the present invention has a hexahedron shape including a front surface 13, a rear surface 11, and four side surfaces 15. Incidentally, of the four sides, one side is made of a structure capable of opening and closing. The one side surface 15a having the openable and closable structure can be hinged or hinged to one side or the other side, the front surface or the rear surface, thereby forming a structure that can be opened and closed. Of course, one side surface 15a having the openable and closable structure can be opened or closed by using a separate cover.

2, the front surface 13 constituting the case 10 of the traffic display panel according to the second embodiment includes an opening 13a for exposing the front surface of the display panel 30 to the outside, And a frame portion 13b for dividing the frame 13a. That is, the front surface 13 of the case 10 is formed by leaving only the outer portion of the plate of a predetermined shape and removing the inside, and the removed portion corresponds to the opening portion 13a, (13b).

The reason why one side surface 15a of the four side surfaces 15 constituting the case 10 is openable and closable is that when the openable side surface 15a is opened, (30) is inserted into the front end of the inner space of the case (10), or the display board (30) inserted into the front end of the inner space of the case (10) can be replaced.

Of course, the light emitting plate 20 may be attached to the rear surface of the internal space or may be pulled out of the attached light emitting plate 20 while the openable side surface 15a is opened. The fixing of the light emitting plate 20 is performed by fixing the mounting surface of the light emitting plate 20 on the rear surface of the inner space of the case 10 at the time of manufacturing the case 10, Is inserted into the front end of the inner space.

In order to insert the display panel 30 into the front end of the inner space of the case 10, an insertion frame 19 is formed at the front end of the inner space of the case 10. The insertion frame 19 is required to slide the display plate 30 from the openable side surface 15a into the internal accommodation space. That is, the insertion frame 19 is necessary to allow the display board 30 to be inserted from the openable side surface 15a and to be fixedly mounted on the front end of the internal accommodation space.

The insertion frame 19 guides and supports the rim of the display panel 30 and is structured so that the rim of the display panel 30 can be inserted while being slid. 3, the insertion frame 19 includes a frame portion 13b constituting the front surface 13 of the case 10 and a side surface 15b excluding the side surface 15a having the openable and closable structure 15 are formed so as to face each other.

That is, the insert frame 19 is composed of the frame portion 13b and a protrusion 15b protruding from the side surface 15 to the inner accommodating space so that the face of the frame portion 13b faces the face of the frame portion 13b . The frame portion 13b and the protruding portion 15b face each other and face each other and are spaced apart from each other. The distance between the frame portion 13b and the protruding portion 15b is set such that the display plate 30 is inserted into the insertion frame 19, The thickness of the display panel 30 is slightly larger than the thickness of the display panel 30. [

3, the protrusion 15b is formed to be higher than the frame portion 13b. However, the protrusion 15b is formed by the protrusion portion and the frame portion which are formed facing each other It is preferable to have the same height in practice.

Since the traffic signboard described above displays the corresponding traffic sign information using light, the light-emitting plate 20 is attached to the rear surface of the case 10 in the interior space.

As described above, the light emitting plate 20 is configured such that the light emitting module plates 20a standardized to a specific size are arranged adjacently in the lateral and longitudinal directions. Therefore, a traffic sign of a specific size can be produced.

 4, each light emitting module plate 20a constituting the light emitting plate 20 includes a base film 21, a circuit pattern 23 printed on the base film 21, And an adhesive plastic film (27) for protecting the base film (21) including the LED (25).

The base film 21 may be an insulating and very thin film. Specifically, any one of PVC (Polyvinyl chloride), PVDC (polyvinyl chloride), PC (Polycarbonate), PP (Polypropylene) and PET (Polyester) films can be used, And the circuit pattern 23 are formed.

A circuit pattern 23 of a predetermined shape is formed on the base film 21. [ The circuit pattern 23 is printed on the base film 21 so that a power source supplied from a power source (a commercial power source or a solar cell or a general battery) can be supplied to the LED 25. The LED 25 is mounted on the base film 21 to be connected to the circuit pattern 23. The LEDs 25 are mounted using SMT equipment.

As described above, the circuit pattern 23 is formed on the upper part, and the base film 21 on which the LED 25 is mounted is protected by the adhesive plastic film 27. That is, the adhesive plastic film 27 having a waterproof function is adhesively bonded to the front surface, the front surface and the rear surface of the base film 21.

The LED 25 and the circuit pattern 23 are protected from moisture or water by bonding the adhesive plastic film 27 to the base film 21 to thereby extend the life of the L traffic sign board, Safety accidents can be prevented. A method of adhering the adhesive plastic film 27 to the base film 21 will be described later.

The circuit pattern 23 is formed on the base film 21 through a printing method. Specifically, as shown in FIG. 4, the circuit pattern 23 is printed on the upper surface of the base film 21 in a predetermined pattern. At this time, the circuit pattern 23 is printed so that the portion where the LED 25 is to be mounted is disconnected. That is, as shown in Fig. 4, the circuit pattern 23 is formed so as to have the disconnection portion 23 '.

And the LED 25 is mounted on the disconnection portion 23 '. Specifically, the LED 25 is mounted on the single-wire portion 23 'so that the positive contact of the LED 25 is connected to one side of the disconnection portion and the negative contact is connected to the other side of the disconnection portion. That is, the LED 25 is mounted so that the disconnected circuit pattern 23 can be electrically connected.

After the LED 25 is mounted on the disconnection portion 23 'of the circuit pattern 23 as described above, silicon is coated on both contact points of the mounted LED 25, Lt; / RTI > Since the base film 21 is soft, the mounted LED 25 may be detached during the bending process. Therefore, it is preferable to perform a process of fixing the two contacts of the mounted LED 25 using silicon.

In order to enhance the structural stability, the light emitting module plate 20a having the above-described structure may be provided with a rigid plate or a separate film which is strong and durable, to the base film 21. [

The light emitting module plate 20a is disposed adjacent to the light emitting module 20 in the lateral and longitudinal directions to constitute the light emitting plate 20 and is attached to the rear surface of the inner space of the case 10 to irradiate the light forward. The light is incident on the display panel 30 attached to the inner front surface of the case 10.

The display panel 30 displays traffic display information having various forms such as numbers, letters, figures, and characters to the outside. That is, in the daytime, the traffic display information is displayed in the same manner as the general traffic display panel, the traffic display information is displayed through the reflection by the headlight of the vehicle during the daytime, and the traffic display information is exposed to the outside through the light transmission .

As shown in FIG. 5, the display panel 30 includes a light diffusion plate 31 for diffusing light emitted from the light emitting plate 20, And a high-luminance reflective sheet (35) which is attached to the transmissive reflective sheet (33) and has an opening (35a) corresponding to the traffic indication information .

The light diffusing plate 31 is formed of a polycarbonate plate having a predetermined thickness to transmit and diffuse the light emitted from the light emitting plate 20.

The light diffusing plate 31 is provided with a transmissive reflective sheet 33 corresponding to a film capable of transmitting most of the light diffused in the light diffusing plate 31 and capable of reflecting light (automobile headlight) ). Therefore, in a state where the transmissive reflective sheet 33 is attached to the front surface of the light diffusing plate 31, the light diffused by the light diffusing plate 31 is mostly emitted to the outside, thereby emitting bright light.

However, since the portion corresponding to the traffic display information must be strongly displayed to the outside, as shown in Fig. 5, the transmission reflection sheet 33 is provided with an opening 35a corresponding to the specific traffic display information Is attached to the reflective sheet 35. The high-

The high-luminance reflective sheet (35) is thicker than the transmissive reflective sheet and has a small light transmittance, and is formed in a color different from that of the transmissive reflective sheet (generally, the reflective reflective sheet White, and the high-brightness reflective sheet is made of blue or green). However, the high-brightness reflective sheet is formed of a material that reflects light that is projected from the outside.

Since the high-luminance reflective sheet 35 is thicker than the transmissive reflective sheet 33 and has a low light transmittance, the light diffused by the light diffusing plate 31 is transmitted through the openings corresponding to the traffic display information The light is transmitted mostly through the transmissive reflective sheet 35 exposed to the outside via the high luminance reflective sheet 35a except for the opening 35a and only a small amount of light is transmitted through the high reflective reflective sheet 35 except for the opening 35a .

Accordingly, when the traffic sign is viewed at night, the open portion 35a corresponding to the traffic indication information corresponding to the portion through which the light is mostly transmitted is very brightly recognized. Therefore, It is possible to recognize quickly and accurately and to recognize the traffic display information even at a long distance.

According to the traffic signboard described above, there is an advantage that the driver can recognize the driver easily, quickly, and remotely at night. 4, since the LED 25 is used as a light source and a separate circuit pattern is formed, it is necessary to protect the LED and the circuit pattern by moisture or moisture . Therefore, there is a need to ensure the airtightness of the light emitting plate 20.

The base film 21 on which the circuit pattern 23 and the LED 25 described above are formed is protected by the adhesive plastic film 27. [ The adhesive plastic film has an adhesive formed on one side of the plastic film. The plastic film may be any one of PVC (polyvinyl chloride), PVDC (polyvinyl chloride), PC (polycarbonate), PP One is preferable.

The LED 25 and the circuit pattern 23 are formed on the base film 21 as described above. Such a base film 21 needs to be protected from external moisture or moisture, and it is necessary to minimize oxidation. For this purpose, the adhesive plastic film 27 must be firmly bonded to the base film 21 and bonded thereto.

Thus, in order to firmly attach the adhesive plastic film 27 to the base film 21, that is, to smoothly attach the adhesive plastic film 27 so that there is no bubble or the like, Thereby performing a method of adhesive bonding to the base film.

Specifically, the process of bonding the adhesive plastic film to the front and back surfaces of the base film on which the circuit pattern is printed and the LED is mounted is performed inside the chamber device shown in Fig.

6, the chamber device 200 includes a chamber 210, a chamber 210, and a holding plate 220. The chamber 210 is held under the chamber 210 in a heated state, A pressure plate 230 installed on the upper side of the chamber for pressing and pressing the adhesive plastic film placed on the fixed base film 21 during the process, And pumping lines 240 and 250 formed in the chamber 210 to form a vacuum atmosphere in the chamber 210. The pumping line is formed of at least one of an upper pumping line 240 and a lower pumping line 250 formed below the chamber.

More specifically, after the base film 21 on which the circuit pattern 23 is printed and the LED is mounted is mounted on the fixing plate 220, the fixing plate 220 is fixed by heating means (not shown) Heat to a temperature.

The base film is preferably placed on the fixing plate heated to a temperature between 60 ° C and 80 ° C. In this state, an adhesive plastic film is placed on the upper portion of the base film. Then, the pressure plate 230 presses the base film on which the adhesive plastic film is placed. That is, the pressure plate contacts and presses the adhesive plastic film placed on the base film.

In this state, a process of converting the inside of the chamber into a vacuum state is performed. That is, the process of attaching the adhesive plastic film to the base film while pumping the air inside the chamber through the pumping line to the outside while maintaining the inside of the chamber in a vacuum state is performed.

Through such a process, bubbles or the like are present between the base film 31 and the adhesive plastic film 27 and can be attached smoothly.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Is also within the scope of protection of the present invention.
