Description

Transmissive panel, traffic sign including the same, and manufacturing method of the traffic sign {Transmissive panel, traffic sign using it and manufacturing method thereof}

The present invention relates to a transmission board, a traffic sign including the same, and a method for manufacturing the traffic sign, and more particularly, by outputting the main information of the traffic sign more clearly through a light-concentrated output method to ensure sufficient night visibility, It relates to a transmissive plate capable of providing more accurate traffic information to drivers, a traffic signboard including the same, and a manufacturing method of the traffic signboard.

In general, signs installed on roads are used as a medium of information transmission to inform drivers of the conditions of the road, and signs using luminous paint or retroreflective paper have been widely used so that drivers can easily check them when driving at night.

However, in the case of a sign using luminous paint or retroreflective paper, the driver must approach the sign or turn on the high beam, and even such recognition becomes impossible when dew condensation occurs. Therefore, since there are many difficulties in recognizing the road conditions in advance and coping safely at night, fog, or rain, road signs using LEDs have recently been used.

In the case of road signs using LED, information on the road sign can be checked from a longer distance than signs using luminous paint, and it is possible to use it semi-permanently due to the nature of LED, so it is gradually becoming widespread and installed. .

However, in the case of LED road signs, even if the output is sufficient due to light reflected inside the traffic sign or light smearing when light is output to the outside, there is a problem that it is difficult for the driver to easily recognize it.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the examples described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same members are sometimes indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

The traffic sign board according to the present invention can be largely defined as including a case 120 and a transmission plate 110.

The case 120 constitutes the overall appearance of the traffic sign board, embeds the light emitting unit 122 inside, and supports the transmission plate 110 in front.

More specifically, the case 120 is coupled to the frame-shaped profile 121, the rear surface of the profile 121, and the back plate 123 to which the light emitting part 122 is temporarily bonded and fixed, and the temporarily fixed It may be exemplified as including a fixing jig 124 coupled to the front of the light emitting part 122 to fix the light emitting part 122 to the back plate 123 .

A projection lens that enhances linearity of light may be coupled to the light emitting unit 122 .

In this embodiment, an LED module may be used as the light emitting unit, but is not limited thereto, and various configurations may be used in a line capable of outputting light.

The profile 121 and the fixing jig 124 will be described in detail in the description of the manufacturing method to be described later.

Next, the transmission plate 110 is coupled to the front of the case 120 and transmits the light of the light emitting unit 122 provided in the case 120 to the outside.

Transmissive plate 110 is a plate shape cut to a certain size, it may form a layered structure.

As a first embodiment of the transmission plate 110, the transmission plate has a structure including a base plate 111 and an opaque layer 115 formed on the front surface of the base plate 111, as shown in FIG. It can be done.

Formation of the opaque layers 112 and 115 described in this description may be implemented in various ways such as transfer, printing, or attachment, and in particular, various methods such as stamp printing, UV printing, eco-solvent printer printing, and silk printing may be adopted in the printing method. can In this description, as an example, hereinafter, forming an opaque layer by a UV printing method will be described as an example, and the formation of the opaque layer is not limited to the above description, and it is revealed that various methods can be used.

Again, a transmission line 117 through which the light of the light emitting unit 122 is transmitted is formed in a region where a portion of the opaque layer 115 is removed, and the light passes through the base plate 111 only through the transmission line 117. can penetrate.

A cover pattern image 116 is formed on the opaque layer 115 , and the cover pattern image 116 may be classified in a manner such as implementing different colors on the opaque layer 115 .

For example, the cover pattern image 116 may be configured in red or blue, and the opaque layer 115 may be configured by using yellow as the rest of the background.

The sign pattern image 116 may be formed of a design including figures, arrows, warning phrases, and the like, which are symbolically used for display, warning, guidance, and the like in normal traffic signs.

By removing the opaque layer 115 along the edge of the cover pattern image 116, a transmission line 117 through which light from the light emitting unit 122 is transmitted may be formed around the edge of the cover pattern image 116. Accordingly, light may transmit through the base plate 111 only through the portion of the transmission line 117 .

In this way, when the opaque layer 115 is removed as necessary, the base plate 111 covered by the removed opaque layer 115 can be exposed to the outside through the transmission line 117, and the transmission line 117 Light is transmitted and reflected to the outside.

When the transmission plate 110 manufactured in this way is viewed from the front, all parts except for the transmission line 117 have an opaque structure and do not transmit light, and by removing the opaque layer 115 Light is exposed to the outside through only the formed transmission line 117 portion.

As a second embodiment of the transmissive plate 110, as shown in FIG. 2, the transmissive plate 110 includes a base plate 111, a reflector sheet 114 attached to the front of the base plate 111, and It may be made of a structure including a second opaque layer 115 printed on the reflector sheet 114 and having a cover pattern image 116 thereon.

The reflector sheet 114 may use a reflector sheet that enables normal retroreflection. The reflector sheet 114 may use a reflector sheet capable of covering the entire front area of the base plate 111 .

Before attaching the reflector sheet 114, surface treatment may be performed to form a certain roughness on the front surface of the base plate 111. The surface treatment may use sandblasting, ultrasonic method, etc., and the specific method is not particularly limited.

Accordingly, the mechanical bonding force between the base plate 111 and the reflector sheet 114 may be improved.

The second opaque layer 115 may be printed using a UV printing method. The second opaque layer 115 has a structure that covers the entire front surface of the base plate 111 to which the reflector sheet 114 is attached, and thus, the front surface of the base plate 111 becomes opaque as a whole.

In some cases, a plurality of unprinted dots d1 may be repeatedly formed on the second opaque layer 115 as shown enlarged in FIG. 2 . At this time, as shown in FIG. 3 , each unprinted dot d1 may be formed at a position eccentric at a predetermined distance from the transmission line 117 and may have a smaller area than the transmission line 117 .

That is, the second opaque layer 115 is not formed with the unprinted dots d1, and thus, the reflector sheet 114 can be exposed toward the front in the portion of the unprinted dots d1. structure is in place Therefore, when the headlights of a car are illuminated from the front, the light emitted from the light emitting part is separately reflected by the retroreflective effect of the reflector sheet 114, and thus the luminance and visibility of the traffic sign can be greatly improved.

The unprinted dot d1 is implemented in various ways, such as performing UV printing while separately masking when printing the second bright light layer 115 or avoiding printing only the unprinted dot d1 portion. can be adopted.

A cover pattern image 116 is formed on the second opaque layer 115 , and the cover pattern image 116 can be distinguished by implementing different colors on the second opaque layer 115 .

For example, the second opaque layer 115 may be configured by configuring the cover pattern image 116 in red or blue and using yellow as the rest of the background.

The sign pattern image 116 may be formed of a design including figures, arrows, warning phrases, and the like, which are symbolically used for display, warning, guidance, and the like in normal traffic signs.

At this time, as shown in FIG. 8, the reflective sheet 114 is removed along the edge of the cover pattern image 116, and the transmission line through which the light of the light emitting unit 122 is transmitted around the edge of the cover pattern image 116 ( 117) can be formed.

Accordingly, light may transmit through the base plate 111 only through the portion of the transmission line 117 .

Since the reflector sheet 114 is first attached to the front of the base plate 111, and then the second opaque layer 115 is formed on the reflector sheet 114 by UV printing, the second opaque layer 115 It is not integrally fixed to the base plate 111, and thus, when the reflector sheet 114 is removed as needed, the base plate 111 covered by the removed reflector sheet 114 is exposed to the outside through the transmission line 117. may be exposed.

That is, in the process of removing the reflector sheet 114, the second opaque layer 115 UV-printed on the reflector sheet 114 is simultaneously removed to form a transmission line 117 on the front of the base plate 111. can

In addition, since the edge portion of the cover pattern image 116 is removed, the light passing through the transparent transmission pattern 113 is transmitted through the transmission line 117 and is reflected to the outside.

When the transmission plate 110 manufactured in this way is viewed from the front, all parts except for the transmission line 117 have an opaque structure and do not transmit light, and by removing the reflector sheet 114 Light is exposed to the outside through only the formed transmission line 117 portion.

Since the transmissive plate 110 forms an opaque area in front of the base plate 111, it prevents light from leaking or transmitting to unnecessary parts, and the transmissive line 117 formed along the circumference of the cover pattern image 116 ), the main information of the traffic sign is more emphasized by concentrating the amount of light more, enabling more accurate information transmission at night.

As a third embodiment of the transmission plate 110, the transmission plate 110, as shown in Figure 3, the base plate 111, the point except for the transmission pattern 113 on the rear surface of the base plate 111 A first opaque layer 112 formed by UV printing, a reflector sheet 114 attached to the front of the base plate 111, and formed on the reflector sheet 114 by UV printing and the transmission pattern 113 ) and a second opaque layer 115 having the cover pattern image 116 in the same form as the cover pattern image 116, and the reflective sheet 114 is removed along the edge of the cover pattern image 116 to cover the cover pattern image 116 border. It has a structure in which a transmission line 117 through which light of the light emitting unit 122 is transmitted is formed around the periphery.

That is, the transmissive plate 110 in this embodiment is different from the above-described embodiments in that both the front and rear surfaces of the base plate 111 are opaque.

More specifically, the first opaque layer 112 may be UV-printed on the rear surface of the base plate 111 except for the transmission pattern 113 .

Accordingly, the rear surface of the base plate 111 has an opaque structure in its overall area due to the first opaque layer 112, and in the case of the transmission pattern 113, it is a portion to which UV printing is not applied, and the rear surface of the base plate 111 It becomes a locally transparent structure on the top of the light emitting unit 122 can be transmitted.

The transmission pattern 113 may be formed of a design including figures, arrows, warning phrases, etc., which are symbolically used for display, warning, guidance, etc. in normal traffic signs.

The first opaque layer 112 opaqueizes the reflective surface of the base plate 111 so that light from the light emitting unit 122 irradiated from the rear surface of the base plate 111 is not reflected from the rear surface of the base plate 111. , It plays a role in enabling intensive induction into the transmission pattern 113.

If the back surface of the base plate 111 is not properly opaque, the light emitted from the light emitting part 122 is diffused or reflected from the base plate 111, causing a problem in that the concentration on the transmission pattern 113 is reduced. do.

The unprinted dot d2 having the same structure as the unprinted dot d1 in the above-described embodiment may also be formed on the first opaque layer 112, and the second opaque layer, which will be described later, may also be an unprinted dot. (d1).

The reflector sheet 114 may use a reflector sheet that enables normal retroreflection. The reflector sheet 114 may use a reflector sheet capable of covering the entire front area of the base plate 111 .

Before the reflection sheet 114 and the first opaque layer 112 are formed on the front and rear surfaces of the base plate 111, surface treatment to form a certain roughness may be performed.

That is, before UV printing or the reflective sheet 114 is attached to the base plate 111, the base plate 111 and the reflective sheet 114 are subjected to surface treatment to give appropriate roughness to the front and rear surfaces of the base plate 111. ) to improve the mechanical bonding force between the first opaque layer (112).

The second opaque layer 115 is formed through a UV printing method and may have a cover pattern image 116 having the same shape as the transmission pattern 113 .

Unlike the first opaque layer 112 that locally forms the transmission pattern 113, the second opaque layer 115 covers the entire front surface of the base plate 111 to which the reflector sheet 114 is attached. Therefore, since the entire front surface of the base plate 111 is opaque, the transmission pattern 113 having a transparent structure is also not observed from the front surface of the base plate 111 .

However, the cover pattern image 116 is formed on the second opaque layer 115. The cover pattern image 116 has the same shape as the transmission pattern 113 and may be formed on the same line as the transmission pattern 113. .

The cover pattern image 116 may be classified in a manner such as implementing different colors on the second opaque layer 115 .

For example, the second opaque layer 115 may be configured by configuring the cover pattern image 116 in red or blue and using yellow as the rest of the background.

The sign pattern image 116 may be formed of a design including figures, arrows, warning phrases, and the like, which are symbolically used for display, warning, guidance, and the like in normal traffic signs.

If the transmission pattern 113 is formed in a circular shape on the rear surface of the base plate 111, a circular cover pattern image 116 may be formed on the same line as the transmission pattern 113 on the front surface of the base plate 111. .

At this time, the edge of the cover pattern image 116 may be configured to be offset by a predetermined distance to the inside of the transmission pattern 113 . In other words, the transmission pattern 113 may be configured to be offset a certain distance outward from the display pattern image.

For example, if the transmission pattern 113 is formed in a circular shape with a predetermined diameter, the cover pattern image 116 is formed in a circular shape with a smaller diameter and concentric with the transmission pattern 113.

This is to more accurately expose the transmission pattern 113 to the removed portion when the edge of the cover pattern image 116 is removed.

At this time, the reflective sheet 114 is removed along the edge of the cover pattern image 116 to form a transmission line 117 through which the light of the light emitting unit 122 is transmitted around the edge of the cover pattern image 116. .

That is, since the reflector sheet 114 is first attached to the front surface of the base plate 111 and then the second opaque layer 115 is formed on the reflector sheet 114 by UV printing, the second opaque layer 115 ) is not integrally fixed to the base plate 111, and thus, when the reflector sheet 114 is removed as needed, the base plate 111 covered by the removed reflector sheet 114 passes through the transmission line 117. may be exposed to the outside.

That is, in the process of removing the reflector sheet 114, the second opaque layer 115 UV-printed on the reflector sheet 114 is simultaneously removed to form a transmission line 117 on the front of the base plate 111. can

In addition, since the edge portion of the cover pattern image 116 is removed, the light passing through the transparent transmission pattern 113 is transmitted through the transmission line 117 and is reflected to the outside.

When the transmission plate 110 manufactured in this way is viewed from the front, all parts except for the transmission line 117 have an opaque structure and do not transmit light, and only the removal of the reflector sheet 114 Light is exposed to the outside through only the portion of the transmission line 117 formed by the above.

Since the transmissive plate 110 forms an opaque layer on both the front and rear surfaces of the base plate 111, it prevents light from leaking or transmitting to unnecessary parts, and the transmissive formed along the circumference of the cover pattern image 116. By concentrating the amount of light only on the line 117, the main information of the traffic sign is more emphasized, enabling more accurate information transmission at night.

Hereinafter, a method of manufacturing a traffic sign board will be described with reference to the accompanying drawings.

The method for manufacturing a traffic sign board according to the present invention includes the steps of preparing a transmission plate 110, preparing a case 120 including a light emitting unit 122 therein, and placing the transmission plate 110 into a case ( 120) is coupled to the front.

First, in order to prepare the transparent plate 110, as shown in FIG. 4, the base plate 111 is formed by cutting the transparent synthetic resin base material m1 into a certain shape (S10). It can be extracted by cutting the base plate 111 in a circular or quadrangular shape in consideration of the shape of a typical traffic sign on the synthetic resin base material (m1).

Next, as shown in FIG. 5, the first opaque layer 112 is UV-printed on the rear surface of the extracted base plate 111 except for the transmission pattern 113 (S20).

In the case of the first and second embodiments of the transmission plate 110 described above, the printing process of the first opaque layer 112 may be omitted.

Again, the entire area of the rear surface of the base plate 111 becomes opaque due to the first opaque layer 112, and in the case of the transmission pattern 113, it is a portion to which UV printing is not applied, and the rear surface of the base plate 111 It becomes a locally transparent structure on the top so that the light of the light emitting unit 122 to be described later can be transmitted. The transmission pattern 113 may be formed of a design including figures, arrows, warning phrases, etc., which are symbolically used for display, warning, guidance, etc. in normal traffic signs.

The first opaque layer 112 opaqueizes the reflective surface of the base plate 111 so that light from the light emitting unit 122 irradiated from the rear surface of the base plate 111 is not reflected from the rear surface of the base plate 111. , It plays a role in enabling intensive induction into the transmission pattern 113.

If the back surface of the base plate 111 is not properly opaque, the light emitted from the light emitting unit 122 is diffused in the base plate 111 and the concentration of the transmission pattern 113 is reduced.

Next, as shown in FIG. 6, an antireflective sheet 114 is attached to the front of the base plate 111 (S30). The reflector sheet 114 may use a reflector sheet that enables normal retroreflection. The reflector sheet 114 may use a reflector sheet capable of covering the entire front area of the base plate 111 .

In the case of the first embodiment of the transmission plate 110 described above, the printing process of the reflector sheet 114 can be omitted, and the opaque layer 115 can be formed directly on the front of the base plate 111 by UV printing. . At this time, of course, the cover pattern image 116 may be formed on the opaque layer 115 .

Meanwhile, between the steps S10 and S20, surface treatment for forming a certain roughness may be performed on the front and rear surfaces of the base plate 111. That is, before UV printing or the reflective sheet 114 is attached to the base plate 111, the base plate 111 and the reflective sheet 114 are subjected to surface treatment to give appropriate roughness to the front and rear surfaces of the base plate 111. ) to improve the mechanical bonding force between the first opaque layer (112).

Next, as shown in FIG. 7, a second opaque layer 115 having a cover pattern image 116 having the same shape as the transmission pattern 113 is UV-printed on the reflector sheet 114 (S40). Unlike the first opaque layer 112 that locally forms the transmission pattern 113, the second opaque layer 115 covers the entire front surface of the base plate 111 to which the reflector sheet 114 is attached. , In step S40, the entire front surface of the base plate 111 is opaque, so that the transmission pattern 113 having a transparent structure is also not observed from the front surface of the base plate 111. However, the cover pattern image 116 is formed on the second opaque layer 115. The cover pattern image 116 has the same shape as the transmission pattern 113 and may be formed on the same line as the transmission pattern 113. .

The cover pattern image 116 may be classified in a manner such as implementing different colors on the second opaque layer 115 .

For example, the second opaque layer 115 may be configured by configuring the cover pattern image 116 in red or blue and using yellow as the rest of the background.

The sign pattern image 116 may be formed of a design including figures, arrows, warning phrases, and the like, which are symbolically used for display, warning, guidance, and the like in normal traffic signs.

If the transmission pattern 113 is formed in a circular shape on the rear surface of the base plate 111, a circular cover pattern image 116 may be formed on the same line as the transmission pattern 113 on the front surface of the base plate 111. .

At this time, the edge of the cover pattern image 116 may be configured to be offset by a predetermined distance to the inside of the transmission pattern 113 . In other words, the transmission pattern 113 may be configured to be offset a certain distance outward from the display pattern image.

For example, if the transmission pattern 113 is formed in a circular shape with a predetermined diameter, the cover pattern image 116 is formed in a circular shape with a smaller diameter and concentric with the transmission pattern 113.

This is to allow the transmission pattern 113 to be more accurately exposed to the area removed when the border of the cover pattern image 116 is removed in step S50 to be described later.

Next, as shown in FIG. 8, the reflective paper sheet 114 is removed along the edge of the cover pattern image 116 to transmit light from the light emitting unit 122 around the edge of the cover pattern image 116. (117) is formed (S50).

Since the reflector sheet 114 is first attached to the front of the base plate 111, and then the second opaque layer 115 is formed on the reflector sheet 114 by UV printing, the second opaque layer 115 It is not integrally fixed to the base plate 111, and thus, when the reflector sheet 114 is removed as needed, the base plate 111 covered by the removed reflector sheet 114 is exposed to the outside through the transmission line 117. may be exposed.

That is, in the process of removing the reflector sheet 114, the second opaque layer 115 UV-printed on the reflector sheet 114 is simultaneously removed to form a transmission line 117 on the front of the base plate 111. can

In addition, since the edge portion of the cover pattern image 116 is removed, the light passing through the transparent transmission pattern 113 is transmitted through the transmission line 117 and is reflected to the outside.

When the transmission plate 110 manufactured in this way is viewed from the front, all parts except for the transmission line 117 are opaque and do not transmit light. Light is exposed to the outside through only the portion of the transmission line 117 formed by the removal of ).

Since the transmissive plate 110 forms an opaque layer on both the front and rear surfaces of the base plate 111, it prevents light from leaking or transmitting to unnecessary parts, and the transmissive formed along the circumference of the cover pattern image 116. By concentrating the amount of light only on the line 117, the main information of the traffic sign is more emphasized, enabling more accurate information transmission at night.

Meanwhile, in step S10 described above, the base material m1 may be cut so that the coupling piece 118 is extended around the edge of the base plate 111 . The purpose of forming the coupling piece 118 will be described later.

Next, a process of preparing the case 120 will be described.

First, the back plate 123 is coupled to the back surface of the frame-shaped profile 121 (S100). The profile 121 in the form of a frame may be prepared by bending an iron plate multiple times, and may have a shape of a figure frame such as a square or a circle according to the shape of the base plate 111.

For example, as shown in FIGS. 12 and 14, the profile 121 is a first horizontal plate 121a placed vertically on the back plate 123, and downwards from the front and rear ends of the first horizontal plate 121a. A pair of first vertical plates 121b vertically bent, a pair of second horizontal plates 121c vertically bent inward from the respective ends of the pair of first vertical plates 121b, At least one end of the pair of second vertical plates 121d and the pair of second vertical plates 121d bent vertically downward at each end of the pair of second horizontal plates 121c. It may be exemplified as including a third horizontal plate 121e formed bent vertically toward the facing second vertical plate 121d.

Accordingly, a support protrusion having an angle of 90 degrees is formed between the second horizontal plate 121c and the second vertical plate 121d, and the edges of the back plate 123 and the transmission plate 110 are seated on the support protrusion. It can be supported, and at this time, the support jaw serves as a stopper to prevent the back plate 123 and the transmission plate 110 from being pushed into the inside of the profile 121 any longer.

In addition, in the case of the third horizontal plate 121e where the light of the light emitting part 122 reaches, it is a structure that shields the inner circumferential surface of the profile 121 having an empty inside by being bent multiple times, and the inside of the profile 121 Since is not opened, the light from the light emitting part 122 is leaked into the profile 121 and the amount of light is not reduced.

At this time, the first horizontal plate 121a constitutes the outer circumference of the profile 121, and the third horizontal plate 121e constitutes the inner circumference, respectively.

On the other hand, a slit 121f is formed through the connection edge of the second horizontal plate 121c and the second vertical plate 121d or on the second vertical plate 121d. The base plate ( 111) can be inserted into the coupling piece 118 formed on the edge.

That is, the coupling piece 118 formed around the rim of the base plate 111 is vertically bent toward the rear of the base plate 111, and then inserted and fixed into the slit 121f, and the bolt member B is inserted into the first number. In the outer direction of the flat plate 121a, the first horizontal plate 121a, the coupling piece 118 inserted into the slit 121f, and the third horizontal plate 121e are continuously penetrated to form the transparent plate 110 into the case. It can be coupled to the front of (120).

Next, the light emitting part 122 is temporarily fixed to the front of the back plate 123 with an adhesive (S200). Subsequently, the light emitting part 122 is fixed to the back plate 123 by coupling the fixing jig 124 to the front of the temporarily fixed light emitting part 122 (S300).

In step S200, the light emitting unit 122 may be temporarily fixed by intensively disposing the light emitting unit 122 at a location where the amount of light should be concentrated.

In general, when the light emitting part 122 is fixed using only the adhesive, the adhesive loses adhesive strength due to the heat dissipation characteristics of the light emitting part 122, so there is a risk that the light emitting part 122 may be removed from the position of the back plate 123. However, by additionally fixing the light emitting part 122 using the fixing jig 124, the positional movement of the light emitting part 122 can be effectively restricted.

At this time, the fixing jig 124 has a plate-shaped structure in which an insertion hole 124a through which the light emitting part 122 is inserted is formed, and an auxiliary anti-reflective sheet 124b is attached to the front side.

Accordingly, the amount of light applied to the front can be further increased by reflecting light from the light emitting unit 122 toward the front, as well as fixing the light emitting unit 122 . The fixing jig 124 may be fixedly installed to the back plate 123 through the bolt member (B).

The case 120 prepared as described above is in a state in which the front is open, and the transmission plate 110 may be coupled to the open front.

At this time, in the process of coupling the transmission plate 110 to the front of the case 120, first, the coupling piece 118 formed on the edge of the base plate 111 is vertically bent to the rear of the base plate 111, and then the transmission plate 110 is placed on the open front of the case 120, and the coupling piece 118 is inserted and fixed into the slit 121f.

When the coupling piece 118 is inserted and fixed into the slit 121f, the coupling piece 118 can be completely inserted into the profile 121 in a state parallel to the third horizontal plate 121e.

The fixing force of the transmissive plate 110 can be exerted from the front of the case 120 only by inserting and fixing the coupling piece 118 into the slit 121f.

In this state, the bolt member (B) is first horizontal plate (121a) in the outer direction of the first horizontal plate (121a), the engaging piece 118 inserted into the slit (121f) and the third horizontal plate (121e) The transmission plate 110 is coupled to the front of the case 120 by fastening so as to continuously pass through.

Accordingly, the bolt member (B) forms its fastening marks only on at least the first horizontal plate 121a and the third horizontal plate 121e of the profile 121, and the transparent plate 110 directly exposed to the outside. ) does not form fastening marks by the bolt member (B) at all on the front side of the bolt member (B), so that the aesthetics of the traffic sign is not damaged or light does not leak through the hole by the bolt, and the transmission plate 110 is the case 120 A structure that is more firmly fastened on the top is provided.

In summary, the present invention is a traffic sign driven by generating natural energy such as wind power and solar heat, even if the light amount of the light emitting part 122 is not sufficiently exhibited due to the low power structure, the case 120 and the transmission plate 110 ), limit unnecessary light leakage, reflection, transmission, etc. of the light emitting unit 122 between them, intensively guide the light irradiation direction toward the front, and at the same time, reduce the circumference of the cover pattern image 116 formed on the transmission plate 110 By concentrating the amount of light only on the transmission line 117 formed along the line, it is possible to manufacture a traffic sign that can secure sufficient night visibility by emphasizing the main information of the traffic sign even under conditions where the amount of light from the light emitting unit 122 is not sufficient. can
