Description

Traffic signs equipped with low-power, high-efficiency, energy-saving lighting

[0001] The present invention relates to a traffic sign equipped with low-power, high-efficiency, energy-saving lighting, and more particularly, to a traffic sign having a three-stage structure comprising an integrated case, a transparent portion coupled to the front of the case, and a plurality of light-emitting LEDs arrayed inside the case, which not only facilitates replacement and maintenance of the partial components, but also, in particular, forms fine perforations in the transparent portion, and inserts spherical beads for light diffusion into each perforation corresponding location to realize a light diffusion effect, thereby ensuring sufficient nighttime visibility even with low light output, and thereby enabling an energy-saving effect, and further, since it can be driven with low power when generating its own power, such as solar power generation, not only ensures power efficiency but also enables an effect of reducing carbon emissions.

[0002] Among the road facilities, there are regulatory, instructional, road surface and caution signs, etc., and these traffic signs are usually made with luminous paint so that they reflect the headlights of running cars and are easy to identify, and some signs are usually installed on curved roads with reflective mirrors attached.

[0003] However, conventional signs such as the above are very dangerous for accidents because they can only be recognized by drivers at relatively close ranges in areas such as construction zones at night or on roads for high-speed driving.

[0004] To improve some of these problems, a technology has been proposed to install a light source such as a light bulb or light-emitting diode on a part of a sign and to connect it to power and operate it in a blinking manner. However, when installing an electrical device that requires power on a road structure, it is necessary to go through electrical work in the surrounding area, and considering the scale of such electrical work, it is true that the introduction of a sign that entails separate electrical work is not very effective.

[0005] Considering these problems, when installing structures that require electricity in road structures, most of them generate their own electricity using natural energy such as solar energy, solar heat, and wind power to meet the rating of the light source. However, considering the power generation efficiency of the typical natural energy power generation system, there was a drawback in that the light source could not provide sufficient light during nighttime hours.

[0006] In addition, considering that the traffic sign structure is installed outdoors, especially in winter, the charging and discharging performance of the battery, which is an essential component of the self-generator, is reduced, which not only reduces power efficiency but also causes the problem of not being able to output traffic information with sufficient light at night.

[0010] The present invention has been created to solve the above-mentioned problems of the prior art, and the purpose of the present invention is to provide a low-power operated light-emitting traffic sign using solar power generation that prevents the battery from being deteriorated in charge and discharge performance due to the drop in temperature in winter and maximizes the operating efficiency by optimizing the temperature of the battery by insulating the battery from the external temperature, and also ensures sufficient nighttime visibility by emphasizing traffic information even under conditions where the amount of light is insufficient, thereby promoting more stable traffic information output even when operating at low power.

[0011] The present invention is a means for achieving the above object, and is characterized by a low-power driving light-emitting traffic sign using solar power generation, including a sign section that provides light-emitting traffic information by emitting light toward a moving vehicle, a solar cell section installed around the sign section and receiving sunlight and converting it into electric energy, and a battery module that is electrically connected to the solar cell section and the sign section and charges the electric energy supplied from the solar cell section and discharges it toward the sign section, and a protective cover section that accommodates the battery module inside and protects it from the outside.

[0012] In addition, it is characterized by further including a vehicle detection sensor that detects a vehicle approaching from the front; and a control unit that controls the flashing of the sign unit based on the detection result of the vehicle detection sensor.

[0013] In addition, the signboard part is characterized by including: a case; a transparent part coupled to the front of the case; a light-emitting part coupled to the case and outputting light toward the transparent part; a shading frame coupled to the outside of the case and protecting the transparent part from sunlight; and a fixing pin coupled to the shading frame and the case so as to penetrate each other and fix the shading frame on the case.

[0014] In addition, the sign portion is characterized by further including a separation nut that is interposed between the case and the awning frame while being fastened to the outside of the fixed pin, thereby spacing the awning frame outward from the case by a certain distance, thereby forming an air passage space therebetween.

[0015] In addition, the above-mentioned sunshade frame is characterized in that a plurality of them are overlapped and connected in a telescopic structure so that the protrusion length toward the front of the case can be adjusted.

[0016] The present invention provides the advantageous effect of preventing the battery from deteriorating in charge and discharge performance due to the temperature drop in winter and maximizing the operating efficiency by insulating the battery from the external temperature and optimizing the temperature of the battery, and also ensuring sufficient nighttime visibility by emphasizing traffic information even under conditions of insufficient light, thereby promoting more stable traffic information output even during low-power operation.

[0047] Before explaining the invention, for the convenience of explanation, by referring to the attached drawings, a non-strict directional reference is specified, and in the state as shown in Fig. 3, up-down (y), left-right (x), and front-back (z) are divided, and the directions are specified and explained according to these references in explanations related to other drawings.

[0048] A low-power driving light-emitting traffic sign using solar power generation according to the present invention (hereinafter referred to as a traffic sign) can be broadly defined as including a sign section (1), a solar cell section (2), a battery module (3), a protective cover section (4), a vehicle detection sensor (5), and a control section (not shown).

[0049] First, the sign section (1) is configured to provide traffic information in the form of light by emitting light toward a moving vehicle, and includes a light emitting section (30) for outputting traffic information in the form of light toward a vehicle passing through the sign section (1) at night. The light emitting section (30) is supplied with power from a battery module (3) and can be operated under the control of a control section. The specific structure of the sign section (1) will be described later.

[0050] Next, the solar cell unit (2) is installed around the sign unit (1) and is configured to receive sunlight and convert it into electrical energy.

[0051] The solar cell unit (2) includes a conventional solar panel and is installed at the top of the traffic sign structure to efficiently collect sunlight. Electrical energy converted from the solar cell unit (2) can be charged into the battery module (3).

[0052] Next, the battery module (3) is electrically connected to the solar cell unit (2) and the sign unit (1), and is configured to charge the electric energy supplied from the solar cell unit (2) and discharge it toward the sign unit (1).

[0053] That is, the light emitting part (30) of the sign part (1) can be operated using electric energy charged in the battery module (3).

[0054] The battery module (3) is a modular structure that includes a battery (secondary battery) that can be charged and discharged, a charging controller that charges the battery with electric energy provided from the solar cell unit (2), a discharge controller that controls the output time and amount of electric energy, and sensors that control and monitor over-discharge and over-charge of the battery, and uses a typical charging and discharging device.

[0055] Next, the protective cover part (4) serves to protect the battery module (3) from the outside by accommodating it inside, and can have a body structure made of a material capable of insulating against external temperature.

[0056] That is, the protective cover part (4) improves the problem of the battery's operating efficiency decreasing due to external temperature, especially in the built-in battery module (3), thereby enabling stable operation of the power demand system within the traffic sign that operates by the power of the battery as well as the light-emitting part (30).

[0057] Next, the vehicle detection sensor (5) is a sensor that detects a vehicle approaching from in front of a traffic sign, and can be implemented with a conventional infrared sensor, radar, lidar, etc.

[0058] When a detection signal is generated from the vehicle detection sensor (5), it is transmitted to the control unit, and the control unit can control the flashing of the light emitting unit (30) of the sign unit (1) based on the detection result.

[0059] The control unit electrically connects the light emitting unit (30), the solar cell unit (2), the battery module (3), the vehicle detection sensor (5), etc., and transmits the battery power, control signals, etc. to each member, and in particular, controls the operation of the light emitting unit (30). The light emitting unit (30) is turned on for a predetermined period of time only when a vehicle approaches the traffic sign, and the light emitting unit (30) is turned off when no vehicle approaches, so that limited power can be used more efficiently.

[0060] Below, the specific structure of the signboard section (1) will be explained.

[0061] The signboard section (1) is broadly defined as including a case (100), a transmitting section (20), a light-emitting section (30), a shading frame (40), a fixing pin (50), and a separation nut (51).

[0062] First, the case (100) constitutes the overall appearance of the traffic sign, has a light-emitting part (30) built into the inside, supports a shading frame (40) to be described later on the outside, and supports a transparent part (20) on the front.

[0063] At this time, the light emitting part (30) can output light toward the transmitting part (20) while being coupled to the case (100).

[0064] The case (100) may be formed in a shape of a body in the form of a figure. For example, in the drawing for explaining the present embodiment, a case in the form of an equilateral triangle is exemplified, but the case is not limited thereto and may be formed in a shape of a circle, a square, etc., according to traffic laws.

[0065] The case (100) can be fixedly installed on a hanger, pole, etc. through a separate bracket so that it can be positioned above a certain height from the road surface.

[0066] The case (100) may be made of metal material so as to maintain structural stability even when exposed outdoors for a long time.

[0067] The front of the case (100) is formed open, and a transparent portion (20) is combined with the open front to form a sealed interior.

[0068] More specifically, the case (100) can be exemplified as including a profile (110) forming a frame of the case (100), a back plate (120) that is coupled to the back surface of the profile (110) and to which the light-emitting part (30) is adhesively fixed to the front surface, and a fixing jig (130) that is coupled to the front surface of the temporarily fixed light-emitting part (30) to fix the light-emitting part (30) to the back plate (120).

[0069] The profile (110) can form the frame structure of the case (100) by bending a hollow pipe of a certain length multiple times and connecting both ends to form a closed loop.

[0070] For example, in the embodiment of the case (100) having a triangular shape as in the present embodiment, the profile (110) may be bent in at least three parts and each end may be connected using a separate bracket, or may be connected by a method such as welding or riveting.

[0071] 4 When a profile (110) is formed using each pipe of each cross-section, the profile (110) may have a 4-section structure in which the outer edge member (111), the back member (112), the inner edge member (113), and the front member (114) are connected to each other at a 90-degree angle with the inner hollow portion as the center.

[0072] An external hole (111a) may be formed by perforation in the upper outer edge member (111) of the profile (110), and an internal hole (113a) may be formed by perforation in the upper inner edge member (113) of the profile (110) to guide heat dissipated from the confined light-emitting portion (30) into the inner space of the profile (110).

[0073] At this time, the outer hole (111a) and the inner hole (113a) are not placed on the same line but may be eccentrically spaced a certain distance up and down. For example, the inner hole (113a) may be placed at a higher point than the outer hole (111a).

[0074] With this structure, the heat dissipated from the light emitting part (30) is not confined in the central sealed space of the case (100), but is discharged into the space inside the profile (110) through the internal hole (113a), while the heat in the space inside the profile (110) is again exhausted to the outside through the external hole (111a), thereby suppressing overheating of the traffic sign.

[0075] Meanwhile, since the external hole (111a) is exposed as it is, there is a possibility that rainwater, etc. may flow in through the external hole (111a). However, even if rainwater flows in through the external hole (111a), since the internal hole (113a) is positioned higher than the external hole (111a), the rainwater flowing into the external hole (111a) does not flow into the sealed space inside the case (100) through the internal hole (113a), but can move to the lower center of the profile (110) along the internal space of the profile (110). At this time, a drainage hole (111b) may be formed through the lower center of the outer edge member (111) to drain the rainwater. A specific description of the configuration of the profile (110) will be described later.

[0076] Next, the back plate (120) is configured to close the open back surface of the profile (110) that is folded in a frame shape, and may be formed of a triangular plate-shaped structure identical to the profile (110), and may be fixedly connected to the back surface member (112) of the profile (110) through a fastening member (not shown) such as a bolt.

[0077] A plurality of light emitting parts (30) can be arranged on the front side of the backing plate (120). At this time, the light emitting parts (30) are temporarily fixed to the front side of the backing plate (120) using an adhesive or the like to initially achieve a rough fixation, and then are trapped between the backing plate (120) and the fixing jig (130) through a fixing jig (130) to be described later to achieve complete fixation.

[0078] Next, the fixed jig (130) is connected to the front of the temporarily fixed light emitting part (30) and serves to fix the light emitting part (30) to the back plate (120).

[0079] The fixed jig (130) has a plate-shaped structure in which a plurality of insertion holes (131) are formed through the corresponding positions of the light emitting parts (30) so that each of the light emitting parts (30) is exposed toward the front.

[0080] The fixed jig (130) can have a reflective sheet attached to the front so that the light from the light emitting unit (30) can be diffused or reflected forward.

[0081] The light emitting unit (30) is configured to be installed on the open front of the case (100) and output light toward the front. In this embodiment, the light emitting unit (30) may be an LED module, but is not limited thereto, and various configurations may be used as long as they can output light. The light emitting unit (30) may be combined with a projection lens that increases the straightness of the light or a diffusion lens that diffuses the light to the surroundings.

[0082] Meanwhile, the case (100) may further include a partition member (140) that protrudes from the backing plate toward the transmission portion (20) to partition an internal sealed space surrounded by the profile (110), the backing plate (120) and the transmission portion (20).

[0083] At this time, the light emitting unit (30) is composed of a plurality of LED modules that output light of different colors (colored) in individual spaces partitioned by the partition member (140), and accordingly, the light output colors within each partitioned individual space are not mixed with each other and can be output in a more intuitive color.

[0084] Meanwhile, in order to reduce power consumption, a partition (140) may be installed between the part with text and cyan and the part without text and cyan, and a light emitting part (30) may be provided only in the part with text and cyan.

[0085]

[0086] Next, the transmitting portion (20) is coupled to the open front of the case (100) and serves to transmit the light output from the light emitting portion (30) in the form of multiple points.

[0087] The transmitting portion (20) is a plate-shaped structure cut to a certain size, for example, a triangular plate-shaped structure identical to the case (100), and can have a structure that implements a mark pattern image on the front in various ways and, in addition, transmits light from the light emitting portion (30) in a dot-like manner toward the front from the perforated structure.

[0088] The penetration portion (20) can be fixed on the front member (114) of the profile (110), and at this time, a third fastening hole (H3) is formed through the front member (114), and a fourth fastening hole (H4) is formed through the edge portion of the penetration portion (20), and a separate fastening member (B1) can be fixed on the profile (110) by mutually penetrating the third fastening hole (H3) and the fourth fastening hole (H4) and joining them.

[0089] The attached drawing shows that the fourth fastening hole (H4) is formed only at the edge of the transmission part (20), but in consideration of improving the fixing strength of the transmission part (20), the fourth fastening hole (H4) may be additionally formed at an inner point of the transmission part (20) that avoids the cover pattern image.

[0090] More specifically, the transmission section (20) can be exemplified as largely including a fixed plate (21) and a transmission bead (22).

[0091] The fixed plate (21) has a plate-shaped configuration with a triangular shape identical to that of the case (100) and a structure in which a plurality of connecting holes (21a) are formed by punching, and has a mark pattern image on the front.

[0092] In some cases, a reflective sheet (21b) may be attached to the front of the fixed plate (21). In this case, the reflective sheet (21b) may be a reflective sheet (21b) that enables normal retroreflection. The reflective sheet (21b) may be a reflective sheet (21b) that can cover the entire front surface area of ​​the fixed plate (21).

[0093] The fixed plate (21) may use an opaque aluminum panel and may include the fourth fastening hole (H4) described above.

[0094] The penetrating beads (22) are in the shape of transparent spheres and are inserted into corresponding locations of each of the plurality of connecting holes (21a) to transmit the light output from the light emitting part (30) in a dot shape toward the front.

[0095] The penetrating beads (22) can use transparent crystals or synthetic resin balls, and the maximum diameter is set to be larger than the diameter and perforation depth (W) of the above-mentioned bonding hole (21a), so that the penetrating beads (22) themselves do not completely pass through the bonding hole (21a) but can be inserted with a portion of the penetrating beads hanging over the edge of the bonding hole (21a).

[0096] At this time, the maximum diameter of the transmission bead (22) is preferably larger than the diameter of the coupling hole (21a) by 0.01 mm to 0.5 mm, and with this structure, the transmission bead (22) can be arranged in the coupling hole (21a) so that a portion thereof protrudes simultaneously to the front and rear sides of the fixed plate (21), and accordingly, the rear protrusion portion (22a) exposed to the rear side of the fixed plate (21) and facing the light emitting portion (30) can collect not only the light from the light emitting portion (30) arranged on the same line as each transmission bead (22), but also the light output at various angles from other light emitting portions (30) eccentric thereto, and the front protrusion portion (22b) exposed to the front side of the fixed plate (21) can spread the collected light at various angles and output it in a surface-emitting manner.

[0097] Accordingly, not only is light transmitted to the front of the traffic sign, but side visibility can be guaranteed by the light focused on the protruding front projection portion (22b) even when the traffic sign is viewed from the side.

[0098] Meanwhile, if the maximum diameter of the penetration bead (22) is larger than the diameter of the bonding hole (21a), but the difference between the maximum diameter of the penetration bead (22) and the diameter of the bonding hole (21a) is within 0.01 mm, the penetration bead (22) and the bonding hole (21a) generally coincide, and in some cases, the penetration bead (22) easily falls out through the bonding hole (21a), which significantly reduces workability during the manufacturing process, and in addition, since the penetration bead (22) is inserted relatively deep into the bonding hole (21a), there is a limit to securing the amount of protrusion to the front and rear of the fixed plate (21).

[0099] On the other hand, if the maximum diameter of the penetration bead (22) is larger than the diameter of the coupling hole (21a), but the difference between the maximum diameter of the penetration bead (22) and the diameter of the coupling hole (21a) exceeds 0.5 mm, the penetration bead (22) cannot be inserted to a sufficient depth into the coupling hole (21a) due to the diameter difference between the two, and thus, the problem of having a biased protrusion amount only toward at least one of the front and rear directions of the fixed plate (21) occurs, resulting in a structural problem of a reduced transmittance.

[0100] Meanwhile, each of the penetration beads (22) partially loaded into the bonding hole (21a) can be fixed using an adhesive (AD). At this time, the adhesive (AD) work is performed on the back of the fixing plate (21) so that no adhesive (AD) marks are exposed on the front of the fixing plate (21), so that each of the penetration beads (22) can be completely fixed to the bonding hole (21a).

[0101] When each of the transmission beads (22) is made transparent and the light of the light emitting part (30) is colored light, the light color of each light emitting part (30) can be expressed more intuitively and transmitted.

[0102] In some cases, a diffusion plate (23) may be installed in the space between the fixed plate (21) and the light emitting part (30), and the diffusion plate (23) serves to diffuse light before it is incident on the back of each transmission bead (22).

[0103] The diffuser plate (23) may be a white plate-shaped structure made of PMMA (Poly Methyl Meth Acrylate) resin or PC (Polycarbonate), and in some cases, may have a structure with a predetermined pattern imprinted on the surface to refract light at various angles so that light can be uniformly transmitted toward the transmission portion (20) over the entire area.

[0104] As another embodiment of the transmission section (20), the transmission section (20) can be exemplified as largely including a first fixed plate (21-1), a second fixed plate (21-2), and a transmission bead (22).

[0105] That is, in the embodiment of the aforementioned penetration portion (20), a single fixed plate (21) was configured, but in this embodiment, it is configured by dividing into a first fixed plate (21-1) and a second fixed plate (21-2), which is different from the aforementioned embodiment.

[0106] Again, the first fixed plate (21-1) and the second fixed plate (21-2) may each have the same structure.

[0107] For example, the first fixed plate (21-1) has a plate-shaped configuration having a triangular shape identical to that of the case (100) and a structure in which a plurality of first coupling holes (21-1a) are formed by punching, and has a mark pattern image on the front.

[0108] In some cases, a reflective sheet (21b) may be attached to the front of the first fixed plate (21-1). In this case, the reflective sheet (21b) may be a reflective sheet (21b) that enables normal retroreflection. The reflective sheet (21b) may be a reflective sheet (21b) that can cover the entire front surface area of ​​the fixed plate (21).

[0109] The first fixed plate (21-1) may use an opaque aluminum panel and may include the fourth fastening hole (H4) described above.

[0110] The first fixed plate (21-1) and the second fixed plate (21-2) can be arranged at a certain distance in the front and rear, respectively, and the first fixed plate (21-1) can be arranged in front of the second fixed plate (21-2).

[0111] The second fixed plate (21-2) has a plate-like configuration having the same triangular shape as the first fixed plate (21-1) and has a structure in which second coupling holes (21-2a) are formed at corresponding positions of the first coupling holes (21-1a).

[0112] That is, each of the first coupling hole (21-1a) and the second coupling hole (21-2a) is arranged on the same line, and a transmission bead (22) is interposed between them.

[0113] The second fixed plate (21-2) may be made of a transparent or translucent material, for example, the same material as the aforementioned diffuser plate (23), and may include a fourth fastening hole (H4).

[0114] The second fixed plate (21-2) is positioned toward the diffuser plate (23) at the rear of the first fixed plate (21-1) and can perform the function of re-diffusing the light diffused and projected through the diffuser plate (23).

[0115] The second fixed plate (21-2) may be made of a colored translucent material, or may have a colored film attached to the front or back to color-filter the projected light.

[0116] A predetermined moving space (24) can be provided between the first fixed plate (21-1) and the second fixed plate (21-2), and a space is provided in which light passing through the second fixed plate (21-2) moves and diffuses through the moving space (24). Accordingly, the uniformity of light transmitted to the middle portion (22c) of the transmission bead (22) interposed between the first fixed plate (21-1) and the second fixed plate (21-2) can be further improved.

[0117] The penetrating beads (22) can be interposed between the first fixed plate (21-1) and the second fixed plate (21-2) which are overlapped with a certain distance from each other, and a portion of the front side can be inserted and fixed into the first connecting hole (21-1a) of the first fixed plate (21-1), and a portion of the rear side can be inserted and fixed into the second connecting hole (21-2a) of the second fixed plate (21-2).

[0118] That is, the front protrusion portion (22b) of the penetration bead (22) is structured to protrude toward the front of the first fixing plate (21-1) through the first connecting hole (21-1a), and the rear protrusion portion (22a) is structured to protrude toward the rear of the second fixing plate (21-2) through the second connecting hole (21-2a), and the middle portion (22c) of the penetration bead (22) is structured to be placed in the moving space (24) which is the space between the first fixing plate (21-1) and the second fixing plate (21-2).

[0119] With this structure, since some of the transmission beads (22) protrude simultaneously from the front and back of the first fixing plate (21-1) and the second fixing plate (21-2), the rear protrusion portion (22a) efficiently collects the light output from each light emitting unit (30) at various angles, and the front protrusion portion (22b) diffuses the collected light at various angles and outputs it in a surface-emitting manner, while the middle portion (22c) collects the light diffused between the first fixing plate (21-1) and the second fixing plate (21-2) to improve the amount of light. In addition, since the second fixing plate (21-2) itself performs the additional function of the aforementioned diffusion plate (23) in a state of close contact with the transmission beads (22), a greater amount of light can be concentrated on the rear portion of the transmission beads (22), and also, when the traffic sign is viewed from the front as a colored structure, each transmission bead (22) is the most It provides a beneficial effect that significantly improves aesthetics by forming a subtle sense of color deep inside and allows for more diverse methods of conveying traffic information.

[0120] Meanwhile, when the transmission part (20) is coupled to the case (100), the fourth connection hole (H4) of the first fixing plate (21-1) and the second fixing plate (21-2) is aligned with the third connection hole (H3) of the front member (114), and the connection member (B1) is fixed by screwing the third connection hole (H3) and the fourth connection hole (H4) to each other. In this way, even without performing a separate adhesive (AD) treatment on the transmission bead (22) interposed between the first fixing plate (21-1) and the second fixing plate (21-2), a structure is formed in which the transmission bead (22) can be fitted and fixed between the first fixing plate (21-1) and the second fixing plate (21-2), and thus a separate adhesive (AD) process can be omitted.

[0121] In other words, since the diameter of the penetration bead (22) itself is larger than the diameters of the first coupling hole (21-1a) and the second coupling hole (21-2a), simply by overlapping and fixing the first fixing plate (21-1) and the second fixing plate (21-2), a fixing structure can be formed in which the penetration bead (22) is firmly inserted without moving between the first fixing plate (21-1) and the second fixing plate (21-2).

[0122] Therefore, it is possible to fundamentally prevent problems such as deterioration of the finish due to adhesive (AD) marks.

[0123]

[0124] Next, the shading frame (40) is connected to the outside of the case (100) and serves to protect the transmission portion (20) from sunlight.

[0125] Due to the nature of the usage environment of traffic signs installed outdoors, when the transparent part is exposed to strong sunlight for a long period of time, the sign pattern image implemented through transfer, printing, sticker attachment, etc. is easily oxidized or deteriorated due to simultaneous and complex long-term exposure to various road pollutants, rain, and ultraviolet rays from sunlight, so the color of the printed part changes or the attachment surface comes off, and sufficient durability is not guaranteed, and as a result, there is a problem that road users are exposed to incorrect information.

[0126] Accordingly, the shading frame (40) can prevent the shading frame (40) from damaging the shading frame (20) by appropriately blocking sunlight applied to the shading frame (20).

[0127] In particular, the awning frame (40) is connected to the outside of the profile (110) of the case (100), and is formed with a closed-loop structure identical to the profile (110) that follows the outer perimeter of the closed-loop-shaped profile (110) so as to cover the profile (110) from all sides, thereby more effectively blocking sunlight from all sides without any blind spots.

[0128] The shading frame (40) is formed to protrude forward by a certain length with respect to the profile (110) to form a shaded area of ​​a certain area on the transparent portion (20). This shaded area can be formed mainly on the edge of the transparent portion (20), thereby preventing heat concentration at the edge of the transparent portion (20).

[0129] In particular, when the metal case (100) and the fixing plate of the transmission part are exposed to sunlight for a long period of time in a season with high atmospheric temperature, such as summer, the surface temperature of the case (100) rises to a considerably high temperature, and this surface temperature of the case (100) is directly conducted to the edge of the transmission part (20) adjacent to the front member (114) of the profile (110) of the case (100), resulting in a temperature rise of the transmission part (20).

[0130] In addition, if the front portion of the transmission section (20) is not properly blocked from sunlight, this also causes a rise in the temperature of the transmission section (20), causing heat to be conducted to both the front and back surfaces of the transmission section (20), resulting in thermal deformation.

[0131] Accordingly, the awning frame (40) can be formed as a closed loop structure that follows the outer rim member (111) while covering the outer rim portion of the profile (110), so that it can primarily block external heat applied to the profile (110), especially the outer rim member (111), and at the same time, it forms a shade on the rim portion of the transmission portion (20) so that radiant heat from sunlight is not directly applied to the transmission portion (20).

[0132] This awning frame (40) can be formed in the same manner as the aforementioned profile (110), for example, a plate of a certain length can be folded multiple times to form a triangular structure corresponding to the profile (110).

[0133] At this time, unlike the aforementioned profile (110), both ends of the awning frame (40) can be joined to the outside of the profile (110) without being joined separately.

[0134] Accordingly, since the two ends of the awning frame (40) are not completely fixed to each other, a certain degree of flexibility is provided, making it easier to manipulate the awning frame (40) for joining the awning frame (40) to the outside of the profile (110).

[0135] For example, since both ends of the awning frame (40) are not completely fixed, if the awning frame (40) is spread to both sides to form a space sufficient to accommodate the case (100) on the inside, and then the awning frame (40) is roughly placed outside the case (100), even if the dimensions for joining the case (100) and the awning frame (40) do not exactly match, the two can be joined easily, which provides the advantage of greatly improving the constructability on site.

[0136] Meanwhile, at the front end of the awning frame (40), an awning piece (41) can be bent and extended vertically toward the center of the awning frame (40) to a certain length.

[0137] At this time, the awning (41) is arranged parallel to the transmission part (20) and serves to block sunlight coming from the front.

[0138] The sunlight applied at low altitudes, such as at sunset or sunrise, cannot be sufficiently blocked by a simple awning frame (40) extending in the forward and backward directions. Therefore, in the case of sunlight applied at such low altitudes, the awning piece (41) is positioned vertically to the awning frame (40) to block the sunlight. In particular, the length of the awning piece (41) is appropriately set so that the front of the transparent portion (20) is not completely blocked by the awning piece (41), so that the transparent portion (20) is exposed to the outside to ensure visibility.

[0139] Meanwhile, a plurality of sunshade frames (40) can be overlapped and combined in a telescopic structure to have a structure in which the protrusion length toward the front of the case can be adjusted.

[0140] That is, a plurality of awning frames (40) are provided, and each awning frame (40) is continuously covered and combined, so that the area of ​​the shaded area can be adjusted by adjusting the position of each awning frame (40) forward and backward.

[0141] For example, when a plurality of sunshade frames (40) are connected to the outside of a case (100) in the order of a first sunshade frame (40-1), a second sunshade frame (40-2), and a third sunshade frame (40-3), the first sunshade frame (40-1) has a structure in which a sunshade member (40-1a) is formed to extend a certain length forward at the top and left and right edge points.

[0142] The remaining second awning frame (40-2) and the second awning frame (40-2) may have a structure in which they are joined in multiple stages by overlapping each other as an arch-shaped structure corresponding to the length of the canopy member (40-1a) rather than a closed loop structure like the first awning frame (40-1).

[0143] A guide hole (40a) may be formed long and penetrating forward and backward on the outer surface of the first awning frame (40-1), the second awning frame (40-2), and the third awning frame (40-3), and an auxiliary coupling hole (40b) may be formed penetrating on one side of the guide hole (40a).

[0144] Although not shown, each guide hole (40a) or auxiliary coupling hole (40b) can be connected and fixed by a guide pin, and the second awning frame (40-2) and the third awning frame (40-3) can be positioned forward and backward within the formation range of the guide hole (40a).

[0145] In addition, when the first awning frame (40-1), the second awning frame (40-2), and the third awning frame (40-3) are all deployed to the maximum, a separate bracket (40-4) covering the first awning frame (40-1), the second awning frame (40-2), and the third awning frame (40-3) is added to the outer surface, and a guide pin is fastened by penetrating through the bracket (40-4) and the first awning frame (40-1) and the third awning frame (40-3), thereby interconnecting and fixing the adjacent first awning frame (40-1), second awning frame (40-2), and third awning frame (40-3).

[0146] In this way, by connecting and fixing the adjacent awning frame (40) through the bracket (40-4), movement or vibration caused by the wind can be blocked in advance to ensure structural stability.

[0147] The number of sunshade frames (40) can be appropriately varied taking into account the installation location of traffic signs, seasonal variables, etc.

[0148] In some cases, the awning frame (40) may be implemented and combined in the form of a structure shaped like a brim of a hat at a specific corner of the profile (110), for example, at the uppermost corner of the profile (110).

[0149] Next, the fixed pin (50) is connected to the awning frame (40) and the case (100) by penetrating each other, and plays a role in fixing the awning frame (40) in position on the case (100).

[0150] At this time, a first fastening hole (H1) and a second fastening hole (H2) into which the fixing pin (50) is inserted and coupled may be formed through the case (100) and the awning frame (40), respectively. Preferably, the first fastening hole (H1) may be formed on the outer edge member (111) of the profile (110), and the second fastening hole (H2) may be formed on the awning frame (40) at a corresponding position to the first fastening hole (H1).

[0151] The fixed pin (50) can use a normal bolt, and although not shown, a nut coupling is built into the inner hollow portion of the profile (110), so that the fixed pin (50) passing through the first fastening hole (H1) can be screwed into the nut coupling, thereby achieving fixation.

[0152] In some cases, the first fastening hole (H1) is configured to successively penetrate the outer edge member (111) and the inner edge member (113) of the profile (110), and when the fixing pin (50) completely penetrates the profile (110) through the first fastening hole (H1), the fixing pin (50) may be fixed by coupling a nut onto the fixing pin (50) exposed by the inner edge member (113) of the profile (110). In addition, the coupling of the fixing pin (50) may be performed in various ways, and thus a detailed description thereof will be omitted.

[0153] Meanwhile, the first fastening hole (H1) has a general circular hole structure that accommodates a fixing pin (50) one-to-one, while the second fastening hole (H2) formed in the awning frame (40) can be formed in a shape that is cut long in the front-back direction at a corresponding position to the first fastening hole (H1).

[0154] Accordingly, the awning frame (40) is fixed to the outside of the profile (110) by a fixing pin (50) so that its position can be arbitrarily adjusted in the front-back direction of the case (100).

[0155] The area of ​​the shade area formed in the transparent portion (20) can be varied by adjusting the position of the awning frame (40) in the front-back direction. For example, if the awning frame (40) is positioned forward, a structure is provided that allows a wider shade area to be formed.

[0156] 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 according to the situation by considering the geographical and topographical characteristics of the traffic sign where it is installed and the meridian altitude according to the season, and the position of the awning frame (40) can be adjusted more easily, thereby ensuring the convenience of maintenance.

[0157] Meanwhile, traffic signs, as road structures, are subject to strong winds (hereinafter referred to as “driving wind”) from moving vehicles, and therefore, the external impact caused by the driving wind must be minimized by appropriately dissipating the driving wind.

[0158] However, due to the structure in which the awning piece (41) is vertically bent and extended to a certain length toward the center of the awning frame (40), the driving wind that collides with the transparent plate (20) is not easily resolved in front of the transparent plate (20) and remains as a swirling vortex, causing a stronger inertial impact and resonance to the traffic sign itself, which causes a problem in that the structural stability is significantly reduced.

[0159] Accordingly, the separation nut (51) is interposed between the case (100) and the awning frame (40) while being fastened to the outside of the fixed pin (50) to space the awning frame (40) from the case (100) to the outside by a certain distance so that an air passage space (Ar) is formed therebetween, thereby allowing the driving wind that has collided with the transparent plate (20) to be smoothly discharged to the rear of the sign section (1) through the air passage space (Ar), thereby reducing resistance to the driving wind.

[0160] In addition, as part of an effort to reduce the influence of such driving wind, the case (110) itself is installed at an angle of about 5 to 20 degrees so that the driving wind that hits the front of the transmission section (20) can smoothly escape downward along the front of the transmission section (20) on the slope.

[0161] Meanwhile, as described above, the profile (110) is formed by bending each pipe multiple times to form a triangular frame structure. At this time, when the pipe material is bent at an acute angle, plastic deformation occurs in an irregular direction at the bent portion.

[0162] For example, when each pipe is bent, there is a problem that elongation occurs in the outer edge member (111) opposite to the bending direction, and compressive deformation occurs due to a load in an irregular direction in the rear member (112), inner edge member (113), and front member (114) excluding this, and a high manufacturing difficulty is required taking this into account.

[0163] Accordingly, in the present embodiment, as a means to prevent such irregular plastic deformation during the bending process of the profile (110), as illustrated in FIG. 18a, a plurality of cuts (115) are formed at equal intervals in a certain section of the length direction of a straight profile (110) (each pipe) before bending, and the section where the cuts (115) are formed is used as a bending point of the profile (110), and as illustrated in FIG. 18b, the profile (110) is bent in the direction in which the cuts (115) are formed, thereby enabling the corner portion of the profile (110) to be bent without irregular shape deformation.

[0164] At this time, each cut (115) has a shape in which the cut area gradually expands toward the outside of the profile (110), for example, a structure in the shape of an isosceles triangle, so that when the profile (110) is bent, plastic deformation of the back member (112), the inner frame member (113), and the front member (114) can be prevented, except for the bending deformation of the outer frame member (111), due to the cut (115).

[0165] Meanwhile, the awning frame (40) can also be formed in the same manner as the folding method of the aforementioned profile (110), and for example, it is possible to form multiple cuts (not shown) at equal intervals in a certain lengthwise section of the awning piece (41) provided on the awning frame (40) in a straight shape before folding.

[0166] Meanwhile, a fine gap is created on the profile (110) by the cut hole (115), and moisture may enter through this fine gap, which may cause a malfunction of the internal electrical device, for example, the light emitting unit (30). Therefore, a sealing tape (116) in the shape of a belt is attached to the front member (114) to prevent moisture from entering through the gap.

[0167] The above sealing tape (116) is configured to prevent moisture from entering through the gap, and is interposed between the front member (114) and the permeable portion (20) to block moisture from entering the case (100). It is characterized by being formed in the form of a band with a full width (W2) that matches the width (W1) of the front member (114) so ​​as not to infringe on the permeable area of ​​the permeable portion (20), and being attached only to the front member (114).

[0168] The sealing tape (116) can be made of an elastic material such as silicone or rubber, and a third fastening hole (H3) of the front member (114) and a fifth fastening hole (H5) communicating with the fourth fastening hole (H4) of the transmission portion (20) are formed through the sealing tape so that the fastening member (B1) can sequentially pass through the third fastening hole (H3), the fourth fastening hole (H4), and the fifth fastening hole (H5) to form a bond.

[0169]

[0170] Hereinafter, another embodiment of the profile (110') will be described. In the above-described embodiment, the profile (110) was formed by integrally forming the frame of the case (100) by bending an internally hollow pipe of a certain length and connecting both ends to form a closed loop. In the following embodiment of the profile (110'), the profile (110') can be formed by disassembling and connecting a plurality of members.

[0171] More specifically, the profile (110') in the present embodiment can be exemplified by including a plurality of pipe members (111') having a structure of straight angle pipes of a certain length, a plurality of corner members (112') that are bent at a certain curvature and connect the ends of each pipe member (111') so that each pipe member (111') can be joined at a certain angle, and a plurality of bracket members (113') that mutually connect and fix the pipe members (111') and the corner members (112').

[0172] That is, in this embodiment, a plurality of pipe members (111'), corner members (112'), and bracket members (113') are connected and combined to form a frame-shaped profile (110'), and by appropriately selecting the number of members, etc., profiles (110') of various geometric shapes can be formed.

[0173] At this time, a first fastening hole (H1) into which the fixing pin (50) is inserted and coupled and a third fastening hole (H3) into which the fastening member (B1) is inserted and coupled may be formed through the edge surface and front surface of each pipe member (111') or corner member (112').

[0174] In addition, a first bracket fastening hole (BH1) may be formed through the end of each pipe member (111'), and a second bracket fastening hole (BH2) may be formed through the end of each corner member (112').

[0175] Each corner member (112') can be formed in the same manner as the formation of the aforementioned profile (110'). For example, the corner member (112') is formed by forming a plurality of cut holes (115) at equal intervals in a certain lengthwise section of a straight pipe before being bent, and bending is performed in the direction in which the cut holes (115) are formed, with the section in which the cut holes (115) are formed as a bending point, thereby enabling the corner member (112') to be bent without irregular shape deformation.

[0176] The cut-out (115) formed in the corner member (112') has the same function and effect as the cut-out (115) described in the embodiment of the above-described profile (110), so a detailed description thereof will be omitted.

[0177] The bracket member (113') can be exemplified as a plate shape of a certain area, and can be fixedly connected to the pipe member (111') and the corner member (112') by means of a bracket fastening pin (114') while one side is inserted into the inside of the pipe member (111') and the other side is inserted into the inside of the corner member (112').

[0178] At this time, a third bracket fastening hole (BH3) communicating with the first bracket fastening hole (BH1) may be formed on one side of the bracket member (113'), and a fourth bracket fastening hole (BH4) communicating with the second bracket fastening hole (BH2) may be formed on the other side, respectively, and the bracket fastening pin (114') may be mutually penetrated and joined to the first bracket fastening hole (BH1) and the third bracket fastening hole (BH3) and the second bracket fastening hole (BH2) and the fourth bracket fastening hole (BH4), so that the pipe member (111'), the corner member (112'), and the bracket member (113') may be integrally joined and fixed to each other.

[0179] In this embodiment, a sealing tape (116) having the same configuration as the sealing tape (116) described above is attached to the front surface of the profile (110') so as to block the gap caused by the cut-out of the corner member (112'). For example, the sealing tape (116) is interposed between the front surface of the profile (110') encompassing the pipe member (111') and the corner member (112') and the permeable portion (20) to block moisture from entering the case (100). In addition, the sealing tape is formed in the shape of a band having a full width (W2) that matches the width (W1) of the profile (110') so as not to infringe on the permeable area of ​​the permeable portion (20), so that it can be attached only to the front surface of the profile (110').

[0180]

[0181] Hereinafter, the process of constructing a signboard portion (1) according to the present invention will be described.

[0182] First, the aforementioned profile (110) is prepared, and the backing plate (120) is attached to the backing member (112) of the profile (110).

[0183] At this time, the back plate (120) can be completely fixed to the back member (112) through a fastening member or a separate welding method.

[0184] Next, the light emitting part (30) is temporarily fixed to the front of the backing plate (120) using an adhesive. Subsequently, a fixing jig (130) is attached to the front of the temporarily fixed light emitting part (30) to completely fix the light emitting part (30) to the backing plate (120). The fixing jig (130) can be fixedly installed at a point spaced a certain distance forward from the backing plate (120) via a fastening member.

[0185] The case (100) prepared in this way has an open front, and a transmission part (20) can be combined with the open front.

[0186] Prior to joining the penetration portion (20), a sealing tape (116) is lined on the front side of the profile, and the edge portion of the penetration portion (20) is placed on the front side of the case (100) so as to be aligned with the sealing tape (116) and joined.

[0187] Next, the awning frame (40) is attached to the outside of the case (100), and after adjusting the front and rear positions of the awning frame (40) to suit the installation environment, the fixing pin (50) is inserted and attached at the matching points of the second fastening hole (H2) and the first fastening hole (H1) to fix the case (100) and the awning frame (40), thereby completing the attachment of the traffic sign.

[0188] In summary, the present invention forms an appropriate shade area around the transmission portion (20), thereby suppressing various deformations such as color change or peeling of the printed portion due to oxidation or deterioration of the transmission portion (20) by strong sunlight even in an environment where it is exposed outdoors for a long time, thereby enabling more objective information delivery to road users and omitting unnecessary maintenance due to deformation of the transmission portion (20), and in particular, by taking into account the geographical and topographical characteristics where the traffic sign is installed and the meridian altitude according to the season, it provides an advantageous effect of significantly improving the range of use.

[0189] The embodiments of the present invention described above are merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent other embodiments are possible. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the detailed description above. Accordingly, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and alternatives within the spirit and scope of the present invention as defined by the appended claims.
