This part only provides background information related to the content of this application and does not necessarily constitute prior art.

Road traffic signs are intended to inform drivers of road conditions, and signs using luminous paint or retroreflective paper have been widely used so that drivers can easily check them while driving at night.

However, signs such as luminous paint or retroreflective paper are difficult to identify from a distance and have poor visibility because they show information through reflection when illuminated by vehicle headlights or street lights.

To solve these shortcomings, backlit road traffic signs using LEDs, such as those in Registration Patent No. 10-1823840, have been proposed. However, they are expensive to manufacture due to the use of large quantities of LEDs, and high maintenance costs due to high power consumption. It takes a lot of time and maintainability is not good.

Meanwhile, Registered Patent No. 10-1065772 includes a road guide sign supported on a prop erected vertically from the ground or a horizontal support extending from the prop and having letters or figures printed on the front surface; Fluorescent wide-angle ultra-high brightness reflective paper attached to the front of the road guide sign; It is configured to include an LED beam irradiator that diffuses and irradiates an LED beam toward the front of the road guide sign, wherein the LED beam irradiator includes an LED and a first lens installed near the front of the LED; A road guide sign including a second lens installed to be spaced apart in front of the first lens and a spacing adjustment member that allows the irradiation range of the LED beam to be adjusted by adjusting the spacing distance between the first lens and the second lens. It is an identification device, and does not focus the light emitted from the beam irradiator onto the road guide sign, resulting in poor visibility.

Registered Patent No. 10-1255678 (expired) is a means of illuminating a sign installed at the top of a sign for road names or road information, including a fastening part on one side with a fitting groove that can be inserted along the upper part of the sign, and an LED It consists of a housing on the other side that can accommodate the device and the substrate and has a light passing groove opening downward, and has an overall side cross-section of an m shape, and is installed within the housing of the lighting fixture body to supply power and It includes an LED element and a substrate that irradiates light downward to illuminate the front of the sign, and the housing of the lighting fixture (main body) is made in the form of a long tube with a circular cross-section, and the LED element and the substrate is accommodated inside the transparent tube, and at the same time, the transparent tube is installed in a concentrically rotatable structure inside the housing, so that the direction of light emitted from the LED device can be adjusted by rotating the transparent tube, It is an LED lighting device for road name and road information signs that is installed side by side along the upper part of the sign by means of a fastening screw that passes horizontally through the thickness of the fastening part and illuminates the sign with light emitted from the LED element. Since the light is directly illuminated, the loss of light is very large, and the direction of the light can be adjusted by rotating the transparent tube. However, since it cannot escape the direct illumination, the loss of light is bound to be large, and also, except for LED elements, the light loss is very large. If only the lighting fixture body needs to be replaced, the entire lighting fixture must be replaced, and there is a problem in that the sign cannot be illuminated.

Registered Patent No. 10-1065772 Registered Patent No. 10-1255678

The present invention is intended to solve the problems described above, and illuminates road traffic signs by irradiating LED light, focuses the LED light on the road traffic signs, and improves visibility by illuminating the entire area of the road traffic signs. In addition, the purpose is to provide an LED unit for road traffic signs and a road traffic sign assembly including the same, which enables replacement of components other than LEDs and illuminates road traffic signs even during such replacement work.

The LED unit for road traffic signs according to the present invention includes a reflector assembled around the periphery of the road traffic sign; It includes an LED that illuminates the road traffic sign by irradiating light, and the reflector is a fixed part of a straight cross-section that overlaps at least one of the front and back sides of the road traffic sign and is fixed through a fastener, and extends from the fixed part. The inner surface is formed in a curved shape to face the road traffic sign, and is connected to the fixing part or the reflection part to reflect the light of the LED to the road traffic sign, and is formed to protrude forward, and the LED is mounted. It is characterized by including an LED mounting part.

The reflector is assembled to the fixing part by dividing the reflector, and the LED mounting part inverts the LED up and down to face the road traffic sign to directly illuminate the road traffic sign with the reflector separated. .

According to the LED unit for road traffic signs according to the present invention and the road traffic sign assembly including the same, it is installed around the perimeter of the road traffic sign and illuminates road information, enabling quick confirmation of road information even at night or in conditions of poor visibility. It has the effect of promoting safe driving, and by fixing the fixed part of the reflector to the road traffic sign, the reflector maintains the linearity of the road traffic sign and expresses a sense of homogeneity, thereby preventing the driver's gaze from going to the LED unit. It has the effect of encouraging safe driving by checking the information, and also has the effect of reducing replacement costs and simplifying replacement work by replacing only the reflector through the split structure of the reflector, and when replacing the reflector, the LED is not replaced again. By converting to direct lighting of traffic signs, road traffic signs can be illuminated, which has the effect of improving the utility as a road traffic sign lighting facility.

In addition, it allows replacement of configurations other than LED, and allows road traffic signs to be illuminated even during such replacement work.

In addition, both existing road traffic signs and new road traffic signs can be easily applied, and maintenance is also very easy.

In addition, it can be supplied at a lower price than existing LED signs, which can stimulate distribution.

In addition, even if the LED is installed on the outside of a road traffic sign, it is protected by a reflector, which has the effect of reducing maintenance costs due to frequent replacement, and improves visibility by reducing the amount of rainwater falling on the surface of the road traffic sign by the reflector. It works.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. The terms described below are defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

As shown in Figures 1 and 2, the LED unit 100 for road traffic signs according to the present invention includes a reflector 10 fixed to the road traffic sign 1 (hereinafter abbreviated as 'sign'), a reflector ( 10) and includes an LED (20) that receives power and irradiates light to the reflector (10) to illuminate the sign (1) through reflection, so as not to obscure the sign content around the sign (1). It is a road traffic sign assembly that is installed to illuminate sign content to ensure visibility at night or in cloudy weather, and includes the above-described sign 1 and the LED unit 100 for road traffic signs.

The reflector 10 includes a fixing part 11 fixed to the sign 1, and a reflecting part 12 that is formed integrally with the fixing part 11 and reflects the light emitted from the LED 20 to the sign 1. , includes an LED mounting portion 13 on which the LED 20 is mounted.

The fixing part 11 overlaps the front or back of the sign 1 and is fixed through fasteners 14 (bolts, nuts, etc.).

While the fixing part 11 has the same straight cross-section as the sign 1 so as to overlap the sign 1, the reflecting part 12 has a curved shape so that the light emitted from the LED 20 can be reflected back to the sign 1. It is made of a cross-section, and this cross-section is a cross-section where the light irradiated from the LED 20 shines toward the surface of the sign (1) through one or more reflections, and the outer end is outside to reflect the light to the sign (1). It is a cross section at an angle where the light is bent towards the sign (1) rather than bent towards the side, and the light is directed to the bottom of the sign (1).

The reflector 12 protrudes forward from the surface of the sign 1 due to its cross-sectional structure, thereby helping to ensure visibility by reducing snow or rain falling on the surface of the sign 1.

The reflector 12 may have both left and right ends closed in order to reduce light loss.

The LED mounting part 13 is installed on the inner surface of the fixing part 11, that is, the surface facing the reflecting part 12, with the width being the direction crossing the reflecting part 12 (for example, at a right angle to the fixing part 11). The left and right directions of the sign 1 are formed to be long in the longitudinal direction, and the LED 20 is installed on the bottom facing the sign 1.

The LED 20 is installed on the LED mounting part 13 to face the reflector 12, irradiates light toward the reflector 12, and uses the light reflected by the reflector 12 to display the sign 1. It illuminates and is used in the form of a bar longer than the width according to the left and right widths of the sign (1), and the control of turning on and off can be controlled in conjunction with street lights and can be controlled based on the detection value of a separate illuminance sensor. Of course, it can also be controlled through manual operation.

The power supply unit that supplies power to the LED 20 is branched from the power supply unit that supplies power to the street lights when nearby street lights are installed, or a solar storage battery that produces electric energy using solar heat (or sunlight) as renewable energy. The form (30) is possible.

According to the LED unit for road traffic signs according to the present invention, the LED 20 receives power from the power supply through control of a controller, turns on, and radiates light to the reflection unit 12.

The light irradiated to the reflector 12 is reflected by the reflector 12 and is irradiated toward the sign 1 to illuminate the sign 1.

The reflector 10 applied to the present invention may be modified as follows.

Figure 3 shows an example of a split configuration of the reflector 10. The reflector 10 is a split type with the fixing part 11 and the LED mounting part 13 as a single body and the reflector 12 as a single piece. And the reflection part 12 overlaps the back of the fixing part 11 and is fixed by fastening the fastener 15.

According to this division method, when only the reflector 12 needs to be replaced, maintenance costs can be reduced by replacing only the reflector 12 while using the fixing part 11 and the LED mounting part 13 as is, and maintenance work can be reduced. In this case, the reflection part 12 can be separated from the fixing part 11 and replaced while the fixing part 11 is fixed to the sign 1 and the LED 20 is maintained, making the work easy.

In addition, the present invention can be configured as follows by using the division method of the reflector 12 so that the LED 20 can be used as is even when the reflector 12 is replaced.

When using the reflector 12, the LED 20 is installed on the upper surface of the LED mounting part 13 and radiates light to the reflector 12. When the reflector 12 is separated, the LED 20 is used as is. If so, the light cannot be reflected to the sign 1, and therefore, the LED mounting part 13 is configured to be rotatable so that the light of the LED 20 can be directly irradiated to the sign 1.

As shown in Figures 4 and 5, the LED mounting part 13 is manufactured as a single piece, and first and second fixing holes (13-1, 13-2) are formed on both sides, and the LED mounting part 13 is rotated for rotation. The means are a fixing bracket 16, which is formed on the fixing part 11 at a certain distance from each other, one side of which is fixed to the fixing part 11, and the other side is arranged next to the LED mounting part 13. It includes a rotation guide shaft 17 that is connected to the LED mounting part 13 and guides the rotation of the LED mounting part 13, and a rocker 18 that fixes the LED mounting part 13 in the rotated position.

The LED mounting part 13 is rotated at an angle of 180 degrees around the rotation guide axis 17 so that if there is a reflector 12, the LED 20 is directed toward the reflector 112 and the reflector 12 is rotated at an angle of 180 degrees. If there is none, it is directed towards the sign (1) and is fixed at each location through a locker (18).

The locker 18 is fastened through or screwed through the fixing bracket 16 using a bolt or pin, and is connected to any one of the first and second fixing holes 13-1 and 13-2 formed on both sides of the LED mounting portion 13. It is fastened to fix the LED mounting part (13). The first fixing hole (13-1) is where the locker (18) is fastened when the LED (20) faces the reflector (12), and the second fixing hole (13-2) is where the LED (20) is connected to the sign (1). When facing, the locker 18 is fastened.

According to this configuration, if the reflector 12 is damaged and needs to be replaced, and the replacement is not quick, the reflector 12 is separated from the fixing part 11. In this case, it can be confirmed that the LED 20 is installed on the upper part of the LED mounting part 13 facing upward, and after removing the rocker 18, the LED mounting part 13 is flipped up and down, and thus, the position of the LED 20 switches to the lower part facing the sign (1).

When the LED mounting part 13 is fixed by fastening the rocker 18 and power is applied to the LED 20, the light of the LED 20 is transmitted directly to the sign 1 and illuminates the sign 1.

Therefore, it is possible to illuminate the sign 1 without stopping the LED 20 in the absence of the reflector 12.

When the reflecting part 12 is replaced, the LED mounting part 13 is reversed to its original position so that the LED 20 is directed to the upper reflecting part 12, and then the sign 1 is indirectly illuminated.

Meanwhile, the reflector 10 may include a drainage part 19 (see FIG. 6) to reduce rain or snow falling on the front of the sign 12. The drain portion 17 is formed on the upper surface of the reflector 10 to slope downward from the center toward both left and right, or from the road side (left side) to the road side (right side) to guide rain or snow to the outside of the sign (1). In this way, it is formed in the form of a groove on the upper surface of the reflector 10 or through a band attached to the surface of the reflector 10.

According to this drainage unit 19, the reflector 10 can collect rainwater, but the rainwater can be guided to the edge of the sign 1 through the drainage unit 19 to prevent visibility deterioration due to rainwater.
