As an example, the road sign 10 includes a case part 100 , a base part B, a fixing ring R, a main light emitting part 300 , a main PCB board 400 , and a sub light emitting part which will be described in detail below. 500 , the sub PCB board 600 , the solar cell 700 , the light guide plate 800 , and the cover part 200 may be included, and although not shown in the drawing, the power generated by the solar cell 700 is stored. It may further include a battery, a communication unit that communicates with an external device, and the like.

That is, in order to clearly explain the core technical idea of the present invention in Figures 1 to 10, some components are omitted and briefly expressed.

Hereinafter, the core technical idea of the road sign 10 will be described in detail.

For example, the case part 100 may be configured to form a predetermined internal space (S1), and to protect the components disposed in the internal space (S1) from an external environment (rainwater, soil, etc.) can

For example, the base part B is disposed on the inner space S1, and is fastened by a fixing member A such as a cover part 200 and bolts and screws, which will be described in detail below, to the cover part ( 200) may be configured to support so that it does not swing on the inner space S1.

For example, the fixing ring (R) is seated on the cover portion 200 disposed on the inner space (S1), the case portion 100 and the fastening member (T) such as bolts and screws It may be fastened to prevent the cover part 200 from being separated from the case part 100 .

For example, the main light emitting unit 300 is disposed on the inner space S1 and may be configured to emit light by power, and may be an LED, but is not limited thereto.

For example, the main PCB substrate 400 may be configured to receive power from the solar cell 700 and/or the battery to supply power to the main light emitting unit 300 , and the main light emitting unit 300 . It may be arranged on the inner space (S1) as a configuration that can control the blinking, etc., and may be arranged to be spaced apart from the base part (B) by a predetermined distance.

For example, the sub light emitting unit 500 is disposed on the inner space S1 and may be configured to emit light by power, and may be an LED, but is not limited thereto, and relatively the main light emitting unit 300 . ) as a configuration in which a small amount of light is emitted with less power, and may be configured to emit light toward the light guide plate 800 , which will be described below.

For example, the sub PCB board 600 may be configured to receive power from the solar cell 700 and/or the battery to supply power to the sub light emitting unit 500 , and the sub light emitting unit 500 . It may be arranged on the inner space (S1) as a configuration that can also control the blinking of the.

For example, the solar cell 700 may be disposed on the inner space S1 and may be configured to generate power through sunlight to supply power to the main light emitting unit 300 .

For example, the light guide plate 800 is a configuration that evenly distributes light. Although not shown in the drawing, fine grooves or irregularities can be formed on the surface, and the light guide plate 800 can be made of a transparent or translucent material. It may be disposed above the cell 700 in the height direction.

For example, the cover part 200 covers the inner space S1 and transmits the light emitted by the main light emitting part 300 and/or the sub light emitting part 500 to the outside, and is transparent or It may be a translucent material.

Hereinafter, the arrangement relationship of each component constituting the road sign 10 will be described in detail.

For example, the main PCB substrate 400 may be disposed to be spaced apart from the base portion B on the inner space S1 by fixing members A such as bolts and screws.

That is, a separation space may be formed between the main PCB substrate 400 and the base portion B.

As a result, the heat generated from the main PCB substrate 400 can be easily dissipated through the separation space.

Here, for example, the main light emitting part 300 may be formed to protrude in the height direction on the main PCB substrate 400 , and may be formed to protrude from the main PCB substrate 400 to be inclined at a predetermined angle. For example, a plurality of the main light emitting units 300 may be formed to be spaced apart from each other in a horizontal direction perpendicular to the height direction.

Here, as an example, the main light emitting unit 300 is electrically connected to the main PCB substrate 400 , and the light emitting body 310 and the light emitting body 310 protrude from the main PCB substrate 400 . A light emitting unit 320 that receives power from and is formed at the end of the light emitting body 310 to emit light may be provided.

For example, the light emitting body 310 may be made of synthetic resin and/or metal, and the light emitting unit 320 may be made of transparent synthetic resin and/or metal as light should pass therethrough.

Meanwhile, as an example, the solar cell 700 may be disposed above the main PCB substrate 400 in the height direction and spaced apart from the main PCB substrate 400 .

That is, a separation space d1 may be formed between the solar cell 700 and the main PCB substrate 400 .

As a result, heat generated from the solar cell 700 and/or the main PCB substrate 400 can be easily dissipated through the separation space d1, and furthermore, the solar cell 700 and the main PCB substrate (400) It is possible to minimize mutual thermal interference.

Here, as an example, the solar cell 700 may be seated on the main light emitting unit 300 protruding from the main PCB substrate 400 to be spaced apart from the main PCB substrate 400 .

For example, the solar cell 700 may be seated on the light emitting body 310 of the main light emitting unit 300 to be spaced apart from the main PCB substrate 400 .

Meanwhile, the sub PCB substrate 600 may be formed to protrude upward in the height direction on the main PCB substrate 400 .

For example, the sub PCB board 600 may be formed to be spaced apart from each other in the horizontal direction.

Here, as an example, the sub light emitting unit 500 receives power from the sub PCB board 600 to emit light, and may be formed to protrude from the inner surface of the sub PCB board 600 in the horizontal direction.

Here, for example, each of the solar cell 700 and the light guide plate 800 may have a side opposite to the sub PCB substrate 600 , and movement in the horizontal direction may be restricted by the server PCB substrate.

To explain this in more detail, the solar cell 700 is arranged so that the side surface is opposite to the inner surface of the sub PCB board 600 so as to minimize fluctuations in the inner space S1, and as a result, the horizontal direction of the sub Movement in a direction toward the PCB substrate 600 may be restricted.

For example, the solar cell 700 may include a solar body 710 that generates power through sunlight and a solar extension 720 that protrudes from the solar body 710 in the horizontal direction. have.

Here, the solar extension portion 720 may be disposed such that a side surface thereof faces the inner surface of the sub PCB substrate 600 so as to minimize fluctuations in the inner space S1 .

In addition, as the solar cell 700 is seated on the main light emitting part 300 obliquely protruding from the main PCB substrate 400 , as a result, in the horizontal direction toward the main light emitting part 300 . movement may be restricted.

On the other hand, the light guide plate 800 is disposed so that the side surface is opposite to the inner surface of the sub PCB substrate 600 so as to minimize fluctuation in the inner space S1, and as a result, the sub PCB substrate 600 in the horizontal direction. Movement in the direction toward may be restricted.

Of course, the light guide plate 800 is fastened to the fixing member (A) so that movement in the horizontal direction may be restricted, but in some cases, the fixing member (A) may be damaged or fluctuate due to tolerance. As the sub PCB board 600 faces the side surface of the light guide plate 800 in the horizontal direction, movement of the light guide plate 800 in the horizontal direction may be restricted.

Also, as an example, the light guide plate 800 may form a through space S3 that is a space through which the main light emitting part 300 penetrates in the height direction.

For example, the through space S3 may be formed by recessing a portion of a side surface of the light guide plate 800 inward in the horizontal direction.

Similarly, as the side surface defining the through space S3 faces the main light emitting unit 300 in the horizontal direction, the light guide plate 800 is consequently directed toward the main light emitting unit 300 in the horizontal direction. Movement in the direction may be restricted.

In addition, the light guide plate 800 includes a light guide body part 810 for dispersing light and a step difference from the light guide body part 810 in the horizontal direction to form at least a part of the sub PCB board 600 in the horizontal direction. A step portion 820 surrounding the sub-light emitting unit 500 in the horizontal direction may be provided.

That is, the step portion 820 surrounds the inner surface and the side surface of the sub PCB board 600 as it faces at least a portion of the inner surface and the side surface of the sub PCB board 600 in the horizontal direction, and moves in the horizontal direction. movement may be restricted.

In addition, as an example, the light guide plate 800 may at least partially overlap the main light emitting part 300 in the horizontal direction and at least partially overlap the sub light emitting part 500 in the horizontal direction. have.

To explain this in more detail, the light guide plate 800 overlaps with the sub light emitting unit 500 in the horizontal direction at least in part to receive and disperse the light emitted by the sub light emitting unit 500 in the horizontal direction. The light emitting unit 320 and at least a part of the main light emitting unit 300 overlap (d2) to receive and disperse the light emitted by the light emitting unit 320 of the main light emitting unit 300, as a result, the user's Visibility can be further maximized.

On the other hand, the cover part 200 has a transmission part 210 that transmits the light emitted by the main light emitting unit 300 , the light emitted by the sub light emitting unit 500 , and the light dispersed by the light guide plate 800 to the outside. ) and a support part 230 extending downward from the transmission part 210 in the height direction to support the sub PCB board 600 .

To explain this in more detail, the support part 230 extends downward from the transmission part 210 in the height direction, and is disposed to face the outer surface of the sub PCB board 600 in the horizontal direction, The sub PCB board 600 may be covered.

As a result, it is possible to prevent the sub PCB board 600 from being shaken or damaged by an external force.
