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.

As shown in FIGS. 11 to 16, the traffic sign board according to the present invention includes a case 10, a transmission plate 110, a sunshade frame 40, a fixing pin 50, and a light emitting part 30. is defined as

The case 10 constitutes the overall appearance of the traffic sign board, and includes the light emitting part 30 inside, supports the awning frame 40 outside, and the transmission plate 110 from the front.

The case 10 may be formed in the shape of a figure-shaped enclosure. For example, in the drawings for explanation of the present embodiment, the case 10 in the form of an equilateral triangle is exemplified, but the case 10 is not limited thereto, and according to traffic laws, it may be formed into a circle, a square, etc. It can be done.

The case 10 may be fixedly installed on a hanger, a support, etc. through a separate bracket so as to be positioned above a certain height from the road surface.

The case 10 is made of a metal material so that it can maintain structural stability even when exposed to the outdoors for a long time.

More specifically, the case 10 is coupled to the profile 1100 constituting the frame of the case 10 and the rear surface of the profile 1100, and the back plate 1200 to which the light emitting part 30 is temporarily bonded and fixed to the front. ) and a fixing jig 1300 coupled to the front of the temporarily fixed light emitting part 30 to fix the light emitting part 30 to the back plate 1200.

The profile 1100 may form the frame structure of the case 10 in such a way that a closed loop is formed by bending an empty square pipe having a predetermined length several times and jointing both ends.

For example, in the embodiment of the triangular case 10 as in the present embodiment, the profile 1100 is bent at least in three parts and each end is connected using a separate bracket, or is connected by welding or riveting. can be configured.

4 When the profile 1100 is formed using each pipe of each cross section, the profile 1100 includes an outer rim member 1110, a rear member 1120, an inner rim member 1130, The front member 1140 may have a quadrangular cross-sectional structure connected to each other at an angle of 90 degrees. A detailed description of configuring the profile 1100 will be described later.

Next, the back plate 1200 is configured to close the open rear surface of the profile 1100 bent in the form of a frame, and may be made of the same triangular plate-shaped structure as the profile 1100, and a fastening member such as a bolt (not shown) ) It can be fixedly coupled on the rear member 1120 of the profile 1100 through.

A plurality of light emitting parts 30 may be disposed on the front side of the back plate 1200, and at this time, the light emitting parts 30 are temporarily fixed to the front surface of the back plate 1200 with an adhesive or the like to be roughly fixed primarily. And, it is confined between the back plate 1200 and the fixing jig 1300 through the fixing jig 1300 to be described later, so that complete fixation can be achieved.

Next, the fixing jig 1300 is coupled to the front of the temporarily fixed light emitting part 30 and serves to fix the light emitting part 30 to the back plate 1200 .

The fixing jig 1300 has a plate-shaped structure in which a plurality of insertion holes 1310 are formed through each of the plurality of light emitting parts 30 at corresponding positions of the light emitting parts 30 so as to expose each of the plurality of light emitting parts 30 forward.

A reflector sheet may be attached to the front of the fixing jig 1300 to diffuse or reflect light from the light emitting unit 30 forward.

In this embodiment, the light emitting unit 30 may be used as an LED module, but is not limited thereto, and various configurations may be used in a line capable of outputting light.

A projection lens that enhances the linearity of light may be coupled to the light emitting unit 30 .

Next, the transmission plate 110 is coupled to the front of the case 10 and transmits the light of the light emitting unit 30 provided in the case 10 to the outside.

Transmissive plate 110 is in the form of a plate cut to a certain size, for example, a plate made of a transparent acrylic material in the same triangular or quadrangular shape as the case 10, and displays a cover pattern image having a translucent or opaque structure on the back or front surface in various ways. It can be implemented as a structure that properly transmits the light of the light emitting unit 30 to the front.

At this time, the sign pattern image can be understood as a concept including figures, arrows, warning phrases, etc. symbolically used for display, warning, guidance, etc. on traffic signs, and can be transferred, printed or It may be implemented in various ways, such as a sticker attachment method. In particular, in the printing method, various methods such as stamp printing, UV printing, eco-solvent printer printing, and silk printing may be adopted. That is, the formation of the transmission plate 110 is not limited to the above description, and various methods may be used, and a detailed description of the transmission plate in this embodiment will be described later.

On the other hand, the transmission plate 110 may be fixed on the front member 1140 of the profile 1100, and at this time, the front member 1140 has a third fastening hole H3, an edge portion of the transmission plate 110 A fourth fastening hole (H4) is formed through, and a separate fastening member (B1) mutually penetrates and couples the third fastening hole (H3) and the fourth fastening hole (H4) to form a profile transmission plate (110). (1100).

Next, the sunshade frame 40 is coupled to the outside of the case 10 and serves to protect the transmission plate 110 from sunlight.

Due to the nature of the usage environment of traffic signs installed outdoors, when the transmission plate 110 provided with the sign pattern image is exposed to strong sunlight for a long time, various problems mentioned in the prior art are caused, and the awning frame 40 is the transmission plate ( 110), it is possible to prevent the transmission plate 110 from being damaged by the sunshade frame 40 by properly blocking sunlight.

In particular, the sunshade frame 40 is coupled to the outside of the profile 1100 of the case 10, and is composed of the same closed loop structure as the profile 1100 following the outer circumference of the closed loop profile 1100 ( 1100) from all sides, and accordingly, sunlight can be more effectively blocked from all sides without blind spots.

The sunshade frame 40 is provided to protrude a certain length forward with respect to the profile 1100 to form a shade area of a certain area on the transmission plate 110, and this shade area is focused on the edge of the transmission plate 110. so that it can be formed, so as to prevent the heat concentration phenomenon of the edge portion of the transmission plate 110.

In particular, when the case 10 made of metal is exposed to sunlight for a long time in a season of high air temperature, such as summer, the surface temperature of the case 10 rises to a significantly high temperature, and the surface temperature of the case 10 is (10), in particular, the front member 1140 of the profile 1100 is directly conducted to the edge of the transmission plate 110 adjacent to the front member 1100, resulting in a temperature rise of the transmission plate 110.

In addition, when adequate sunlight cannot be blocked from the front of the transmission plate 110, this also causes a temperature rise of the transmission plate 110, and heat is conducted to both the front and rear surfaces of the transmission plate 110, resulting in thermal deformation. will do

Accordingly, the awning frame 40 covers the outer rim of the profile 1100 and has a closed loop structure that follows the outer rim member 1110 so that the profile 1100, especially the outer rim member 1110 In addition to being able to play a role of primarily blocking the applied external heat, a shade is formed around the edge of the transmission plate 110 to prevent radiant heat from sunlight from being directly applied to the transmission plate 110.

The sunshade frame 40 may be formed in the same manner as the profile 1100 described above, and for example, a triangular structure corresponding to the profile 1100 may be formed by bending a plate material having a certain length a plurality of times.

At this time, both ends of the awning frame 40 may be coupled to the outside of the profile 1100 in a state in which they are not jointed separately, unlike the profile 1100 described above.

Accordingly, since both ends of the awning frame 40 are not completely fixed to each other, a predetermined ductility is imparted to facilitate the operation of the awning frame 40 for coupling the awning frame 40 to the outside of the profile 1100. can do.

For example, since both ends of the awning frame 40 are not completely fixed, the awning frame 40 is opened on both sides to form a space sufficient to accommodate the case 10 on the inside, and then to the outside of the case 10. If the awning frame 40 is roughly arranged, even if the dimensions for coupling the case 10 and the awning frame 40 do not exactly match, it is possible to easily combine the two, thereby significantly improving the workability at the site. to provide.

On the other hand, at the front end of the sunshade frame 40, the sunshade piece 41 may be bent and extended vertically toward the center of the sunshade frame 40 by a predetermined length.

At this time, the awning piece 41 is disposed parallel to the transmission plate 110 and serves to block sunlight applied from the front.

Sunlight applied at a low altitude of the sun, such as sunset or sunrise, is a structure that cannot be sufficiently blocked with only the awning frame 40 extending in the forward and backward directions. In the case of sunlight applied at such a low altitude, the awning frame 40 The transmission plate 110 is blocked through the vertically disposed awning piece 41, and the length of the awning piece 41 is appropriately set so that the front of the transmission plate 110 is not completely blocked by the awning piece 41. ) is exposed to the outside to ensure visibility.

Next, the fixing pin 50 passes through the sunshade frame 40 and the case 10 and serves to fix the position of the sunshade frame 40 on the case 10 .

At this time, a first fastening hole H1 and a second fastening hole H2 through which the fixing pin 50 is inserted and coupled may be formed through the case 10 and the sunshade frame 40, respectively. 1 fastening hole H1 may be formed on the outer frame member 1110 of the profile 1100, and the second fastening hole H2 may be formed on the sunshade frame 40 at a position corresponding to the first fastening hole H1. .

An ordinary bolt may be used as the fixing pin 50, and although not shown, a nut coupling is built into the hollow portion of the profile 1100 so that the fixing pin 50 passing through the first fastening hole H1 is the nut. It can be fixed by screwing into the coupling.

In some cases, the first fastening hole (H1) is made of a structure that continuously passes through the outer rim member 1110 and the inner rim member 1130 of the profile 1100, and the fixing pin 50 is the first fastening hole. When completely penetrating the profile 1100 through (H1), the fixing pin 50 may be fixed by coupling a nut on the fixing pin 50 exposed to the inner frame member 1130 of the profile 1100. In addition to this, since the coupling of the fixing pin 50 can be made in various ways, a detailed description will be omitted.

On the other hand, in the case of the first fastening hole H1, while having a general circular hole structure for accommodating the fixing pins 50 one-to-one, the second fastening hole H2 formed in the sunshade frame 40 is the first fastening hole. (H1) so that it can be made in the form of a long incision in the front and rear direction at the corresponding position.

Accordingly, in a state in which the sunshade frame 40 is fixed to the outside of the profile 1100 by the fixing pin 50, the position can be adjusted in the forward and backward directions of the case 10 at will.

As the position of the awning frame 40 is adjusted in the front-back direction, the area of the shade area formed on the transmission plate 110 can be varied. The structure that can form the shade of is equipped.

In this way, since the position of the awning frame 40 can be adjusted according to the situation, it is possible to form an appropriate shade area suitable for the situation in consideration of the geographical and topographical characteristics where the traffic sign is installed and the midday altitude according to the season. It is possible to more conveniently perform position adjustment of the awning frame 40 so as to ensure the convenience of maintenance.

On the other hand, as described above, the profile 1100 bends each pipe multiple times to form a triangular frame structure. At this time, when each pipe material is bent at an acute angle, plastic deformation occurs in an irregular direction at the bent portion. .

For example, when each pipe is bent, elongation occurs in the outer rim member 1110 opposite to the bending direction, and in the rear member 1120, the inner rim member 1130, and the front member 1140 other than this, due to loads in irregular directions. This is a problem in which compression deformation occurs, and a high manufacturing difficulty in consideration of this is required.

Therefore, in this embodiment, as a means for preventing such irregular plastic deformation during the bending process of the profile 1100, as shown in FIG. 17A, the longitudinal direction of the straight profile 1100 (angular pipe) before bending A plurality of incisions 1150 are formed at equal intervals in a certain section, and the section in which the incisions 1150 are formed is used as a bending point of the profile 1100, as shown in FIG. 17B. Incisions 1150 are formed By bending the profile 1100 in the direction, it is possible to bend the corner of the profile 1100 without irregular shape deformation.

At this time, each incision 1150 has a shape in which the incision area gradually expands toward the outer direction of the profile 1100, for example, a structure in the form of an isosceles triangle, and accordingly, when bending the profile 1100 Due to this incision 1150, it is possible to prevent plastic deformation of the rear member 1120, the inner rim member 1130, and the front member 1140 except for the bending deformation of the outer rim member 1110.

On the other hand, the awning frame 40 may also be formed in the same way as the bending method of the profile 1100 described above, for example, a certain section in the longitudinal direction of the awning piece 41 provided on the awning frame 40 in a straight shape before being bent. Of course, it is possible to form a plurality of incisions (not shown) at regular intervals.

On the other hand, a fine gap is generated on the profile 1100 by the cutout 1150, and moisture may flow in through the fine gap to cause failure of the internal electrical device, for example, the light emitting unit 30, A band-shaped sealing tape 1160 is attached to the front member 1140 to prevent moisture from entering through the gap.

The sealing tape 1160 has a configuration in consideration of preventing the inflow of moisture due to the gap, and is interposed between the front member 1140 and the transmission plate 110 to block the inflow of moisture into the case 10, and the transmission plate ( It is characterized in that it is attached only to the front member 1140 in the form of a band having a full width W2 corresponding to the width W1 of the front member 1140 so as not to infringe on the transmission area of 110).

The sealing tape 1160 may use an elastic material such as silicone or rubber, and a fifth coupling hole H3 of the front member 1140 communicates with the fourth coupling hole H4 of the transmission plate 110. The fastening hole H5 is formed through so that the fastening member B1 can be coupled by successively passing through the third fastening hole H3, the fourth fastening hole H4, and the fifth fastening hole H5.

Hereinafter, another embodiment of the profile 1100' will be described with reference to FIGS. 21 to 24. In the profile 1100 in the above-described embodiment, if the frame frame of the case 10 is configured integrally by bending an empty square pipe of a certain length and combining both ends to form a closed loop, the following In the embodiment of the profile 1100', the profile 1100' can be configured in a disassembly and coupling manner in which a plurality of members are connected and coupled.

More specifically, the profile 1100' in this embodiment is composed of a plurality of pipe members 1110' composed of straight angular pipes of a certain length, bent at a certain curvature, so that each pipe member 1110' has a constant A plurality of corner members 1120' connecting the ends of each pipe member 1110' so that they can be jointed at an angle, and a plurality of corner members 1120' interconnecting and fixing the pipe members 1110' and corner members 1120'. It may be exemplified as including the bracket member 1130'.

That is, in the present embodiment, it is possible to construct a frame-shaped profile 1100' by connecting and combining a plurality of pipe members 1110', corner members 1120', and bracket members 1130', respectively, with each other. It is possible to configure the profile 1100' of various shapes by appropriately adopting the number of them.

At this time, the first fastening hole H1 into which the fixing pin 50 is inserted and coupled to the edge surface and the front surface of each pipe member 1110' or corner member 1120' and the fastening member B1 are inserted and coupled. Third fastening holes H3 may be formed through each.

In addition, a first bracket fastening hole BH1 may be formed at an end of each pipe member 1110' and a second bracket fastening hole BH2 may be formed at an end of each corner member 1120'.

Each corner member 1120' may be formed in the same way as the above-described profile 1100'. For example, the corner member 1120' forms a plurality of incisions 1150 at equal intervals in a certain section in the longitudinal direction of each pipe in the form of a straight line before being bent, and the section in which the incisions 1150 are formed is the bending point. By bending in the direction in which the cutout 1150 is formed, the corner member 1120' can be bent without irregular shape deformation.

Since the cutout 1150 formed in the corner member 1120' has the same functions and effects as the cutout 1150 described in the above-described embodiment of the profile 1100, a detailed description thereof will be omitted.

The bracket member 1130' may be exemplified in the form of a plate of a certain area, and one side is inserted into the inside of the pipe member 1110' and the other side is inserted into the inside of the corner member 1120', and the bracket fastening pin ( 1140' may be fixedly coupled to each of the pipe member 1110' and the corner member 1120'.

At this time, one side of the bracket member 1130' has a third bracket fastening hole BH3 communicating with the first bracket fastening hole BH1, and a fourth bracket fastening communicating with the second bracket fastening hole BH2 on the other side. Holes BH4 may be formed through each, and the bracket fastening pin 1140' may be formed through the first bracket fastening hole BH1, the third bracket fastening hole BH3, the second bracket fastening hole BH2, and the fourth bracket. The pipe member 1110', the corner member 1120', and the bracket member 1130' can be integrally coupled and fixed to each other by being mutually penetrated and coupled to the fastening hole BH4.

A sealing tape 1160 having the same configuration as the above-described sealing tape 1160 is attached to the front of the profile 1100' in this embodiment so that the gap caused by the cutout of the corner member 1120' can be shielded . For example, the sealing tape 1160 is interposed between the front side of the profile 1100' encompassing the pipe member 1110' and the corner member 1120' and the transmission plate 110 to block the inflow of moisture into the case 10. It may be made in the form of a band having a full width (W2) matching the width (W1) of the profile (1100') so as not to infringe on the transmission area of the transmission plate (110) and can be attached only to the front of the profile (1100'). let it be

Next, the transmission plate 110 is coupled to the front of the case 120 and transmits the light of the light emitting unit 30 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.

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 the light of the light emitting unit 30 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.

On the other hand, the transmission line 117 is usually implemented by cutting and removing the surface of the opaque layer 115 with a sharp tool such as a cutter. At this time, the cutter covers not only the opaque layer 115 but also the surface of the base plate 111. While being removed together by the base plate 111, an intaglio groove 117' with a certain depth following the transmission line 117 may be formed.

In the case of the edge portion of the opaque layer 115 in contact with the intaglio groove 117 ', as it is exposed to the harsh outdoor environment, it relatively easily loses adhesive power compared to other areas, resulting in a problem of lifting. Line 117 is filled with transparent silicon 117'' so that it can be hardened by being deeply injected into the recess 117'.

Accordingly, the transparent silicone 117'' firmly adheres and fixes the edge of the opaque layer 115 to effectively suppress lifting, and if necessary, a transparent acrylic protective plate is bonded to the front of the opaque layer 115. so that the durability of the opaque layer 115 can be improved.

Intaglio grooves, transparent silicon, transparent acrylic protective plates, etc. may be applied as they are in embodiments to be described later.

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, as illustrated in the enlarged view of FIG. 2 , unprinted dots d1 having a small area may be repeatedly formed on the second opaque layer 115 .

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.

At this time, 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 .

When printing the second opaque layer 115, the unprinted dot d1 is implemented in various ways, such as performing UV printing while separately masking 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 making the rest of the background color, such as yellow.

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 30 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 the light of the light emitting unit 30 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 and can transmit the light of the light emitting unit 30 .

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 30 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 from the light emitting part 30 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).

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 .

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 30 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.

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 process of constructing a traffic sign according to the present invention will be described.

First, the above-described profile 1100 is prepared, and the back plate 1200 is coupled to the rear member 1120 of the profile 1100.

At this time, the back plate 1200 may be completely fixed on the back member 1120 through a fastening member or a separate welding method.

Next, the light emitting part 30 is temporarily fixed to the front of the back plate 1200 with an adhesive. Subsequently, the fixing jig 1300 is coupled to the front of the temporarily fixed light emitting part 30 to completely fix the light emitting part 30 to the back plate 1200. The fixing jig 1300 may be fixedly installed at a point spaced a predetermined distance forward from the back plate 1200 through a fastening member.

The case 10 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.

Prior to combining the transparent plate 110, the sealing tape 1160 is lined on the front of the profile, and the edge of the transparent plate 110 is placed on the front of the case 10 to match the sealing tape 1160. combine

Then, the sunshade frame 40 is coupled to the outside of the case 10, but after adjusting the front and rear position of the sunshade frame 40 according to the installation environment, the fixing pin 50 is connected to the second fastening hole H2. 1 By inserting and coupling to the matching point of the fastening hole (H1) to fix the case 10 and the sunshade frame 40, the coupling of the traffic sign is completed.

In summary, the present invention forms an appropriate shade area around the transmission plate 110, so that the transmission plate 110 is oxidized or deteriorated by strong sunlight even in an environment exposed to the outdoors for a long time, so that the color of the printed part is changed or detached. It suppresses various deformations such as falling, enabling more objective information transmission to road users, and omitting unnecessary maintenance due to deformation of the transmission plate 110. In particular, geographical and topographical characteristics where traffic signs are installed It provides an advantageous effect of greatly improving the range of utilization by enabling the formation of an appropriate shade area suitable for the situation by considering the midday altitude and the season.

Hereinafter, steps for preparing the transmission plate 110 will be described with reference to the accompanying drawings.

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 30 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.

If the back surface of the base plate 111 is not properly opaque, the light emitted from the light emitting unit 30 is diffused in the base plate 111 and the concentration on 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. .

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 30 around the edge of the cover pattern image 116. (117) is formed (S50).

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 ).

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 unit 30 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 30 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 through the transmission line 117 formed along the line 117, it is possible to manufacture a traffic sign capable of ensuring sufficient night visibility by emphasizing the main information of the traffic sign even under conditions where the amount of light of the light emitting unit 30 is not sufficient. can

The embodiments of the present invention described above are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. It is also to be understood that the present invention includes all modifications, equivalents and alternatives within the spirit and scope of the present invention as defined by the appended claims.
