[0046] (Example 1-6) A traffic sign utilizing an LED of the present invention is formed on the display device (700) in Example 1-4 and includes a speaker that transmits a warning sound.

[0047] The present invention relates to a traffic sign using LEDs, and specifically, a traffic sign using LEDs can improve the visibility of letters and prevent glare by utilizing LEDs (301). Referring to FIG. 1, traffic signs using LEDs include various types of signs (100) installed in various locations such as roads (20), sidewalks, etc., such as speed signs (100), warning signs (100), etc., in which LEDs (301) are mounted on letters to prevent glare and increase color purity, thereby assisting drivers or drivers to easily identify the signs during the day or at night. At this time, the traffic sign using LEDs is fixed to a support (110) that is formed by being fixed to the ground and extending upward, and LEDs (301) are mounted on the signs (100) on which various letters are displayed to emit light. In addition, the signs (100) may be formed of metal or synthetic resin, and each material may be used separately or simultaneously.

[0048] Referring to FIGS. 2 and 3, a signboard (100) like this can be formed in various shapes such as a circle, a triangle, a square, etc., and a measuring device (500) that measures the speed of a vehicle (10), the driving direction, the condition of the road (20), etc. is formed on the signboard (100). The measuring device (500) is formed inside the signboard (100) to measure the vehicle (10) on the road (20), and can be formed in various ways such as a speed measuring sensor, an AI camera, a radar, a laser, etc. At this time, the measuring device (500) measures the vehicle (10) through a measuring hole formed on the signboard (100), and a cover is formed on the measuring hole to prevent foreign substances from entering.

[0049] Additionally, a charging device (600) is formed to charge electricity to supply power to the LED (301) and is installed on the upper part of the support (110). The charging device (600) can charge electricity using various methods such as solar power, wind power, and geothermal heat.

[0050] And, a display device (700) is formed at the bottom or top of the sign (100) to convey information to a driver or pedestrian, and the display device (700) displays the driving direction and speed of the vehicle (10), the condition of the road (20), road (20) information, etc. in letters or symbols. In addition, the display device (700) may be formed integrally with the sign (100) at the top or bottom or may be formed to be spaced apart from each other, and when the display device (700) and the sign (100) are formed to be spaced apart from each other, a connecting part (710) is formed that is connected to a support (110) that supports the sign (100), and the connecting part (710) may be formed as a clamp and fixed to the support (110). And, a display part (720) is formed at the front of the connecting part (710), and the display part (720) displays various information received through the control device (800). To explain this in detail, the driving direction of the vehicle (10), such as forward or reverse driving, the speed of the vehicle (10), and the weather of the road (20) can be displayed in the measuring device (500).

[0051] In this way, the display device (700), sign (100), measuring device (500), etc. can be controlled by the control device (800), and the control device (800) can receive information through an external control center and transmit the information to the outside.

[0052] Accordingly, the traffic sign utilizing the LED of the present invention has a feature that can improve visibility by mounting the LED (301) according to the character shape of the sign (100).

[0053]

[0054] (Example 2-1) The present invention relates to a traffic sign utilizing LED, and in Example 1-1, it includes a front plate (200) formed on the sign (100) and having a plurality of through holes (201) through which letters are displayed and air passes; a light-emitting substrate (300) formed on the rear surface of the front plate (200) and having a plurality of LEDs (301) mounted thereon according to the shape of letters; and a rear plate (400) that fixes the light-emitting substrate (300) and is coupled to the front plate (200).

[0055] (Example 2-2) A traffic sign utilizing an LED of the present invention includes, in Example 2-1, the through hole (201) and the LED (301) being located at the same position.

[0056] (Example 2-3) A traffic sign utilizing an LED of the present invention includes, in Example 2-2, the front plate (200) and the light-emitting substrate (300) being formed at a certain distance from each other.

[0057] (Example 2-4) A traffic sign utilizing an LED of the present invention includes a spacer for maintaining a gap, which is formed between the front plate (200) and the light-emitting substrate (300) in Example 2-1.

[0058] (Example 2-5) A traffic sign utilizing an LED of the present invention includes a reflector formed in the through hole (201) and reflecting light in Example 2-5.

[0059] (Example 2-6) A traffic sign utilizing an LED of the present invention includes a finishing member that is connected between the front plate (200) and the rear plate (400) in Example 2-5 and prevents foreign substances from entering.

[0060] The present invention relates to a signboard (100), and specifically, the signboard (100) displays letters or symbols and emits light. Referring to FIG. 4, the signboard (100) is formed of metal or synthetic resin. When the signboard (100) is formed of a metal such as brass, copper, aluminum, or stainless steel, it is preferable to form the signboard (100) of a material having high thermal conductivity in order to eliminate heat generated when the LED (301) emits light. In terms of thermal conductivity of metals, copper is the highest, followed by aluminum, and brass is the lowest.

[0061] In the case of copper, although it has high thermal conductivity, it may not be suitable because it is relatively soft and heavy compared to other metal materials, and when two or more materials are mixed and used, it can only be used in some parts.

[0062] Aluminum is commonly used as a heat-dissipating material. It is resistant to low temperatures, rusts, and has excellent corrosion resistance. Compared to other metals, it is lightweight, non-toxic, easy to cast, has a certain level of rigidity, and offers excellent recyclability. Brass, on the other hand, offers excellent workability, corrosion resistance, electrical conductivity, relatively high strength, and low price.

[0063] The front plate (200) as described above displays characters and transmits light emitted from within to the outside to improve the readability of the characters. A plurality of through holes (201) may be arranged according to the characters or symbols, and the through holes (201) are formed at the same position as the LEDs (301) that emit light on the back of the front plate (200). In addition, the area of ​​the through holes (201) may be formed to be equal to or larger than the area of ​​the LEDs (301), and a reflector is attached to the inside of the through holes (201) so that the light amount of the LEDs (301) is smoothly irradiated to the outside through the holes. In addition, characters or symbols at the same positions as the through holes (201) are displayed on the front of the front plate (200), and the characters or symbols are attached by printing or urethane adhesive. At this time, the urethane adhesive can prevent browning from occurring over time.

[0064] And the light emitting substrate (300) installed on the back of the front plate (200) can be equipped with multiple LEDs (301) formed in the same position as the through hole (201) positioned according to the shape of the character, and the type of the LED (301) is not limited. In addition, the light emitting substrate (300) is formed so that the LED (301) does not come into contact with the front plate (200) by a certain distance from the front plate (200), which prevents the front plate (200) and the LED (301) from coming into contact with each other and being damaged by an external impact. At this time, a spacer is formed between the light emitting substrate (300) and the front plate (200), and the spacers are formed so as to be arranged at equal intervals. In addition, a reflector can be attached to the spacer to prevent light from being absorbed by the spacer.

[0065] And, a rear plate (400) for fixing the light emitting substrate (300) is formed on the rear side of the light emitting substrate (300), and the rear plate (400) can fix the light emitting substrate (300) by a fastening member. In addition, the rear plate (400) is formed to be combined with the front plate (200), and both sides of the rear plate (400) and the front plate (200) are finished by a finishing member. The finishing member can be installed to wrap the rear plate (400) and the front plate (200), and a packing is formed on the inside of the finishing part to prevent foreign substances from entering through the finishing member.

[0066] The rear plate (400) serves to fix the light-emitting substrate (300), and may be exposed to the outside or may be combined with a separate housing. In addition, the rear plate (400) may be manufactured from either synthetic resin or metal, like the front plate (200). Since the rear plate (400) contacts the light-emitting substrate (300) to fix the light-emitting substrate (300), considering that heat generated from the LED (301) is transferred by contact with the light-emitting substrate (300), it may be manufactured from a material with high thermal conductivity, that is, a metal such as aluminum, brass, or copper, similar to the front plate (200).

[0067] A fastening hole for connection with the front plate (200) and a substrate fixing hole for fixing the light-emitting substrate (300) to the rear plate (400) may be formed through the rear plate (400). The fastening holes formed in each of the front plate (200) and the rear plate (400) may correspond in position to each other. The position of the substrate fixing hole formed in the rear plate (400) may vary depending on the position of the light-emitting substrate (300) located on the front of the rear plate (400).

[0068] The front plate (200), the light-emitting substrate (300), and the rear plate (400) can be connected to each other through a predetermined means, and the rear plate (400) can serve as a kind of housing that protects the light-emitting substrate (300).

[0069]

[0070] (Example 3-1) The present invention relates to a traffic sign utilizing LED, and in Example 2-1, it includes an anti-reflection film (210) attached to one surface of the front plate (200) to increase the legibility of letters by reducing the reflectance of light; and a quantum dot film (220) attached to the other surface of the front plate (200) to improve the visibility of LED (301).

[0071] (Example 3-2) A traffic sign utilizing an LED of the present invention includes, in Example 3-1, the anti-reflection film formed by an anti-glare film.

[0072] (Example 3-3) A traffic sign utilizing an LED of the present invention includes, in Example 3-1, a quantum dot material applied to one surface of the second film; and an adhesive material applied to the other surface of the quantum dot material.

[0073] The present invention relates to a front plate (200), and specifically, the front plate (200) displays characters and emits light from an LED (301) to the outside. Referring to FIG. 5, the front plate (200) has a plurality of through holes (201) formed therein so that light emitted from the LED (301) inside can be transmitted to the outside, and an anti-reflection film (210) and a quantum dot film (220) formed on both sides of the front plate (200) can improve visibility during the day or at night.

[0074] The anti-reflection film (210) is attached to the front surface of the front plate (200) to prevent rainwater or dust from entering through the through hole (201) formed in the front plate (200). The front surface of the anti-reflection film (210) can be anti-glare (AR) treated. Anti-glare (AR) is an optical coating method that means lowering reflectivity. The anti-glare (AR) treated film has the characteristic of reflecting light regularly. The surface of the anti-glare (AR) treated film has a shape in which fine irregularities are formed.

[0075] The quantum dot film (220) refers to a film containing quantum dot particles, and receives light from a backlight, i.e., an LED (301), transmits the light, and implements color. When the LED (301) emits blue light, the quantum dot film (220) can convert the blue light into white light by exciting billions of red and green quantum dot particles contained within the quantum dot film (220). However, the present invention does not limit the type of LED (301) of the quantum dot film (220) to a blue light LED (301), and the LED (301) may be a white light LED (301). This is because the quantum dot particles contained in the quantum dot film (220) change even in white light.

[0076] The conventional method was a method in which a traffic sign was formed on the front, and an LED (301) was illuminated on the back of the traffic sign to display letters or marks, and an optical fiber connected to the LED (301) was illuminated to display letters or marks. However, this method consumed a lot of power, and during the day, only a distinction was possible by a reflector, so there was a problem in that drivers or pedestrians could not easily identify the signs.

[0077] The present invention implements a character or mark to be expressed using an LED (301) and a quantum dot film (220), thereby reducing the glare of light passing through the quantum dot layer and improving color purity.

[0078] The quantum dot film (220) may include a quantum dot material applied to one side of the front plate (200). The quantum dot material itself has a certain adhesive strength, so that the quantum dot film (220) can be easily attached to the front plate (200). However, if the adhesive strength of the quantum dot film (220) is insufficient, a separate adhesive material may be applied together with the quantum dot material to enable the quantum dot film (220) to have adhesive strength.

[0079]

[0080] (Example 4-1) The present invention relates to a traffic sign using an LED, and in Example 3-1, it includes a board substrate (310) formed on the light-emitting substrate (300), on which a plurality of LEDs (301) are mounted and fixed to the rear plate (400); and a control device (320) formed on the rear surface of the board substrate (310) and controlling temperature by electric power.

[0081] (Example 4-2) A traffic sign utilizing an LED of the present invention includes a bracket formed on the back of the light-emitting substrate (300) in Example 4-1 and preventing deformation of the board substrate (310).

[0082] (Example 4-3) A traffic sign utilizing an LED of the present invention includes a support member formed on the bracket and connecting both ends of the board (310) in Example 4-2.

[0083] (Example 4-4) A traffic sign utilizing an LED of the present invention is formed on the board substrate (310) in Example 4-2 and includes a fastening groove to which an LED (301) is fastened.

[0084] The present invention relates to a light-emitting substrate (300), and specifically, the light-emitting substrate (300) is formed with a plurality of LEDs (301) mounted thereon to emit light. Referring to FIG. 6, the light-emitting substrate (300) is formed on the back of the front panel (200) to emit light with the LEDs (301), and a board substrate (310) on which a plurality of LEDs (301) are mounted is formed. A fastening groove for fastening the LEDs (301) is formed on the board substrate (310), and the LEDs (301) are formed at the same position as the through-holes (201) formed according to the character shape of the front panel (200). In addition, a control board for adjusting the color and illuminance of the LEDs (301) is formed on the board substrate (310), and the control board is controlled by the control device (800) to control the plurality of LEDs (301).

[0085] In addition, a bracket is formed on the back of the light-emitting substrate (300) to prevent deformation of the board substrate (310). Considering that the light-emitting substrate (300) is relatively thin and is installed externally, the bracket can prevent problems such as the light-emitting substrate (300) from being bent due to external factors. In addition, since a support member connecting both ends of the board substrate (310) is formed on both ends of the bracket, bending of the board substrate (310) can be prevented.

[0086] And the control device (320) is formed on the back of the board substrate (310), and can control the heat of the LED (301) mounted on the board substrate (310) by controlling the temperature by power.

[0087]
