One side of the support member 600 is coupled to the coupling unit 700 and the other side of the support member 600 is coupled to the control unit 500 to support the control unit 500 in the center of the inside of the frame 100.

One or more supporting members 600 may be radially coupled to the inner center of the frame 100 to correspond to the coupling unit 700.

At this time, the support member 600 is made of a transparent material so that the advertising film 201 is not shaded, and is coupled to the coupling unit 700 and the control unit 500 in a press-fitting manner or in a screw-tight manner.

More specifically, the support member 600 is formed of a hollow pipe, and includes cable for supplying power to the control unit 500 from the outside, operation control information from the control module 500 to the LED module 300, A cable for feeding the cable is inserted into the cable.

The translucent plate 200 is made of transparent or opaque synthetic resin material and is mounted on both sides of the frame 100 by being coupled with a commercial film 201 on which a commercial text or a graphic is displayed on one side. And is formed in a circular or polygonal shape.

At this time, the light transmitting plate 200 is formed with side portions extending from the periphery and bent in the direction of the frame 100, and the step portion 101 of the frame 100 is fitted to the inside of the side portion and is engaged with the frame 100 .

A pair of such transparent plates 200 are fitted and fitted to both sides of the frame 100 in a state where the advertising film 201 on which advertising characters or graphics are displayed is coupled to the inner or outer side.

The protruding double-sided signboard 10 according to the present invention is configured such that the control unit 500 is spaced apart from the pair of translucent panels 200 by a certain distance from the advertisement film 201 so that the shade is not adhered to the advertisement film 201 And the light diffusion spread is uniformly irradiated to the advertisement film 201 to clearly display the printed advertisement text.

Also, since the control unit 500 is disposed inside the frame 100 so as not to be exposed to the outside and is supported by the support member 600 made of a transparent material, it is possible to prevent electric safety accidents.

A reflector 400 formed of a triangular prism and formed in a shape corresponding to the shape of the frame 100 and disposed closely to the LED module 300 installed around the inside of the frame 100; .

That is, the present invention is characterized in that a reflector 400 formed of a triangular prism and formed in a shape corresponding to the shape of the frame 100 is disposed closely to the LED module 300 installed inside the frame 100, 403 reach a half point around the light transmitting plate 200 by total reflection.

Accordingly, the LED module 300 is mounted on the substrate such that the LED chip (light source) such as the COB type or the SMD type is mounted on the substrate at uniform intervals so that the amount of light radiated to the transparent plate 200 is evenly distributed.

3, the LED module 300 is installed as shown in an exploded perspective view, and the reflector circumferential surface 402 closely contacts the light emitting surface of the LED module 300 with a reflector (not shown) 400 are installed.

It is preferable to use the triangular prism 401 as the reflector 400 and to provide the reflector circumferential surface 402 closely to the LED module 300 so that the reflector oblique surface 403 is disposed on both sides of the transparent plate 200, As shown in FIG.

When the power is applied to the LED module 300, the LED module 300 emits light, and the light enters the triangular prism 401 through the reflector circumferential surface 402.

5, the light is refracted while passing through the triangular prism 401 used as the reflector 400, and the light is incident on the reflector 400 due to the straightness of the light incident on the reflector circumferential surface 402 Since the critical angle at the boundary formed by the density difference of the reflector 400 is incident at a large angle, total internal reflection is totally reflected inside the reflector 400 and is incident on the opposite reflector bevel 403, Since the incident angle incident on the oblique plane 403 is smaller than the original angle of critical angle, it can be passed through and diffused to the advertising film 201 around the peak 405. At this time, light reflected by the oblique plane 403 of the reflector Since the refraction angle of refraction is set so as to reach the half of the both surfaces of the transparent plate 200, that is, the center of the transparent plate 200 by total reflection, even when the diameter of both surfaces of the transparent plate 200 is large, The angle of reflected light is sufficient so that the diffusion range of the light can reach 1/2 of the diameter of the transparent plate 200. [

At this time, even if the angle of light reflected by the reflector oblique surface 403 is sufficient and the diffusing range of light reaches a half of the diameter of the transparent plate 200, the illuminance of the central portion of the translucent plate 200 is lower than that of the transparent plate 200 Problems that appear dark may arise.

In this case, as shown in FIG. 6, a suitable number of "v" grooves (hereinafter referred to as "serration") 404 in the direction of the tip 405 of the reflector bevel 403 are densely formed The amount of scattering of light increases toward the leading edge 405, so that even when the diameter of the double-sided billboard is large, the amount of light reaching 1/2 of the diameter of the light transmitting plate 200 is sufficient and uniformity over the entire surface of the light transmitting plate 200 It radiates light in a degree of light.

As described above, since the light is uniformly emitted from the periphery of the translucent plate 200 to the center of the advertising surface by the reflector 400, which is light in weight and can be manufactured at low cost, high visibility and advertising effect are provided.

 7, the reflector 400 is also required to be formed in a quadrangular shape. In this case as well, as shown in some cutaway perspective views, the shape of the triangular prism 401 Of course. According to this embodiment, as shown in FIGS. 8 to 11, the LED modules 300 in each direction from the circumferential surface of each reflector 400 to the boundary line indicated by the dot-dash line respectively irradiate half of the advertisement surface As a result, the light is superimposed and irradiated by the LED module 300 that irradiates light on the adjacent surface to each surface, and as a result, a sufficient amount of light can be emitted from the light-transmitting surface.

8 is a state in which light is irradiated by the LED module installed on the lower circumferential surface of the reflector according to the present invention in which FIG. 7 is applied. In addition, The light is superimposed because the light is irradiated by the LED module installed on the other peripheral surface of the reflector on the right side of the drawing.

In addition, in the present invention, as shown in FIG. 10, in the state shown in FIGS. 8 and 9, the light from the LED module installed above the reflector is superimposed.

In addition, as shown in FIG. 11, in the state shown in FIG. 8, FIG. 9 and FIG. 10, light of the LED module installed on the left side of the drawing of the reflector is irradiated, It is possible to improve the visibility of the contents of the advertisement in a state in which the luminous intensity is improved.

12, the reflector 400 and the LED module 300 are pushed into the clip 102 so that the interposer 103 of the clip 102 tightens the oblique face of the reflector 400 So that a rigid assembled state can be maintained without being detached by vibration or the like. FIG. 13 shows such assembled state.

14, since the LED module 300 disposed on the inner circumference of the frame 100 is disposed in a position different from that of the adjacent LED module 300, It is possible to increase the spectral efficiency evenly dispersed even in a wide range.

FIG. 15 is a cross-sectional view of such an installation example. By doing so, an ideal light emitting state can be obtained by selectively arranging the LED module 300 when the peripheral surface width of the reflector 400 is narrow or wide.

As described above, the protruding double-sided signboard 10 of the present invention is provided with the reflector 400 closely to the LED module 300 installed around the inside of the frame 100, thereby reducing the number of LEDs, The effect can be maximized.
