The traffic signal sign is used to identify the traffic signal sign for easy identification. Efforts are being made to improve.

Recently, a method of irradiating light from one surface while light is scattered by a pattern by passing the light emitted from the light source through a plate-shaped light guide plate having a predetermined pattern is used.

Such a conventional light guiding unit includes a light guide plate having a scattering pattern formed in a lattice shape on an upper surface thereof, and an LED installed on one side of the light guide plate. When light emitted from the LED is incident on the light guide plate, light incident on the light guide plate is received. Scattered by the grid-shaped scattering pattern formed in the emitted light is emitted to the outside through one surface of the light guide plate.

However, the above-mentioned conventional light guiding unit is not emitted to the outside through only one surface of the light guiding plate as described above, and thus, the utilization of the rear side of the light guiding unit is remarkable by using it as a coupling part of the support for supporting the light guiding unit. In addition to the deterioration, there was a problem in that the appearance of the light guide unit was inhibited by the structure of the coupling portion of the support.

In addition, the scattering of the light is scattered at the intersection of the scattering pattern. In the conventional light guiding unit, the intersection of the light and the scattering pattern is increased as the intersection of the scattering pattern is varied according to the irradiation angle of the light emitted from the LED. Not only the brightness distribution efficiency of the light is significantly lowered due to the contrast between the site and the site where the light and the scattering pattern have a small intersection, but the light hitting the blocking plate cannot be utilized.

The present invention is devised to solve the above problems, the object of the present invention is to improve the rear utilization of the light guide unit by allowing light to be emitted from both the top and rear of the main body, that is, both sides, the light guide unit It is to provide traffic signal signs that can significantly improve the sense of beauty.

In addition, a plurality of circular scattering patterns are formed concentrically on the upper surface of the circular light guide plate so that the intersection of the light and the scattering pattern irradiated radially from the light emitting means is made uniform throughout, thereby significantly improving the luminance distribution efficiency of the light guide plate. To provide traffic signs.

It provides a traffic signal sign comprising a second light guide plate installed in.

In addition, any one of a text and a figure may be printed on the upper surface of the guide phrase, and may further include a pair of cover members respectively provided on the upper and lower surfaces of the main body.

In addition, the first and second light guide plates may be formed in a circular shape, and the scattering pattern may be formed in plural concentrically on the bottom surface of the first light guide plate.

In addition, it is preferable that the spacing of the plurality of scattering patterns decreases toward the center of the light guide plate.

The light emitting part may be installed at a position corresponding to an area where the first light guide plate and the second light guide plate contact each other.

According to the present invention as described above, by utilizing the light emitted from both the upper and rear surfaces, that is, both sides of the main body can significantly improve the rear utilization of the light guide unit, there is an effect that can significantly improve the appearance of the light guide unit. .

In addition, a plurality of circular scattering patterns are formed concentrically on the upper surface of the circular light guide plate so that the intersection of the light and the scattering pattern irradiated radially from the light emitting means is made uniform throughout, thereby significantly improving the luminance distribution efficiency of the light guide plate. It can be effective.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in these drawings, the traffic signal sign 1 according to an embodiment of the present invention includes a main body 10, a light emitting unit 20, a first light guide plate 30, a second light guide plate 40, It consists of a pair of cover member (50).

The main body 10 is formed of a substantially disk-shaped steel material, the receiving space 11 is formed inside, the upper and lower surfaces, respectively, the first exposure hole 12 so that the receiving space 11 is exposed to the outside And the second exposed hole 13 is formed.

The reason for forming the first exposure hole 12 and the second exposure hole 13 on the upper and lower surfaces of the main body 10 is that light emitted from the first light guide plate 30 and the second light guide plate 40 to be described later is the main body. This is to allow the upper and lower surfaces of the 10 to be emitted to the outside through both sides of the main body 10.

The main body 10 provides an installation space of the light emitting unit 20, the first light guide plate 30, and the second light guide plate 40, which will be described later, and prevents the light emitted from the light emitting unit 20 from escaping to the outside. And guide the first light guide plate 30 and the second light guide plate 40 to each other.

The light emitting unit 20 may be a light emitting diode (LED), which is a conventional semiconductor lamp, and a plurality of light emitting diodes are radially installed along the inner wall surface of the main body 10 of the receiving space 11 of the main body 10. It is.

Here, the plurality of light emitting units 20 may be disposed at equal intervals to improve luminance of the first light guide plate 30 and the second light guide plate 40, which will be described later, and the first light guide plate 30 and the second light guide plate 40 may be used. The light guide plate 30 may be disposed at a position corresponding to a region where the first light guide plate 30 and the second light guide plate are in contact with each other.

It is apparent that the light emitting unit 20 is well known to be able to purchase and use a commercially available one to those skilled in the art, and a detailed description thereof will be omitted.

The first light guide plate 30 is formed in a substantially disk shape, and is installed in the accommodation space 11 of the main body 10 so that the upper surface thereof is exposed through the first exposure hole 12.

In addition, a plurality of circular scattering patterns 31 are formed on the bottom of the first light guide plate 30, and the scattering pattern 31 includes light emitted from the light emitting unit 20. When incident to the light scattered incident light serves to uniformly transmit the incident light to the upper surface of the first LGP 30 and the bottom of the second LGP 40.

Here, the scattering pattern 31 is formed in plural with the center of the first light guide plate 30 as a concentric circle, it is preferable that the interval is smaller toward the center of the first light guide plate 30.

The reason why the spacing between the scattering patterns 31 is made smaller toward the center of the first LGP 30 is that the light irradiated from the light emitting part 20 provided on the outer side of the first LGP 30 is the first LGP. Since the amount decreases toward the center of the light guide plate 30, the luminance of the first light guide plate 30 is increased by increasing the intersection of the light and the scattering pattern 31 toward the center of the first light guide plate 30 to make the scattering rate of the light uniform throughout. This is to improve the distribution efficiency.

In addition, the scattering of light by the circular scattering pattern 31 formed in a concentric shape and the resulting brightness enhancement of the first LGP 30 will be described in detail with reference to FIG. 4.

Here, the second LGP 40 may form a scattering pattern on the upper surface of the first LGP 30 in contact with the first LGP 30, like the first LGP 30. Since scattering is performed, it is preferable not to form a scattering pattern on the second LGP 40 in order to shorten the processing cost and work time of the traffic signal sign 1 according to the present embodiment.

In the present embodiment, the shapes of the main body 10, the first light guide plate 30, and the second light guide plate 40 are described in a circular manner, but the present invention is not limited thereto, and the shape is not limited thereto. Of course, it can be made of a polygon.

The cover member 50 is formed in a disc shape formed of acrylic material, and a guide phrase made of letters and figures related to a caution sign and a speed limit indicator traffic signal is formed on one surface thereof, and the first exposure hole 12 and the second exposure hole are formed.
