The first ice layer 110 and the second to fourth ice layers 130, 140, and 160, which will be described later, may be formed to a predetermined thickness by repeating the cooling process after spraying water with a spraying device or the like.
제 1 빙층(110)의 상부에는 백색의 페인트를 도포할 수가 있는데, 백색의 페인트 층(120)은 아래의 제 1 빙층(110) 및 바닥면 등이 외부에서 보여지는 것을 방지하도록 함과 동시에 전체 디스플레이 화면의 배경 색상으로 사용될 수 있도록 한다.

The second ice layer 130 including the display module 200 may be formed on the white paint layer 120. In FIG. 1, the heights of the display module 200 and the second ice layer 130 are the same, but the display module 200 is formed under the second ice layer 130, that is, of the display module 200.

The unit display modules may be formed at predetermined intervals on the PCB substrate 210. The light source unit 220 may be formed. As described above, the light source unit 220 emits light from the inside of the ice body to the upper surface to enable display display through the surface of the ice plate.
이때, 본 실시예에서 사용되는 광원부(220)로는 발광다이오드를 사용할 수가 있는데, 각각의 단위 디스플레이 모듈에는 복수의 RGB 발광다이오드가 형성될 수가 있다. In this case, a light emitting diode may be used as the light source unit 220 used in the present embodiment, and a plurality of RGB light emitting diodes may be formed in each unit display module.
집광부(230)는 광원부(220)로부터 조사된 빛을 반사시켜 집광시키는 부재로 광원부(220)를 둘러싸며 빛의 조사 방향으로 연장되도록 형성될 수가 있다. 이때, 집광부(230)는 광원부(220)로부터 조사된 빛이 분산되어 퍼지는 것을 방지하고 상부를 향하여 집광시킴으로써 광 손실을 줄이고 보다 선명한 디스플레이 영상을 구현할 수 있도록 한다. The light collecting unit 230 may be a member that reflects and collects light emitted from the light source unit 220, and may be formed to surround the light source unit 220 and extend in a light irradiation direction. At this time, the light collecting unit 230 prevents the light emitted from the light source unit 220 is dispersed and spread, and condenses toward the top to reduce the light loss and to implement a clearer display image.
집광부(230)의 형태는 도 4의 (a)에 도시되어 있는 것과 같이 빛의 조사 방향을 따라서 반경이 점차적으로 커지고 단면이 직선면을 형성하는 구조일 수도 있고, 도 4의 (b)와 같이 빛의 조사 방향을 따라서 반경이 점차적으로 커지되 단면이 2차 곡선면을 형성하는 구조일 수도 있는데, 이에 한정되는 것은 아니다. The shape of the light collecting part 230 may be a structure in which the radius is gradually increased along the irradiation direction of light and the cross section forms a straight surface as shown in (a) of FIG. 4. Likewise, the radius may gradually increase along the irradiation direction of light, but the cross section may form a secondary curved surface, but is not limited thereto.
도 3에 도시되어 있는 것과 같이 집광부(230)의 상부에는 투명 재질로 형성된 투명 커버(242)가 형성될 수가 있는데, 투명 커버(242)는 광원부(220)로부터 조사되어 집광부(230)를 거친 빛을 외부로 투과시키도록 한다. 이때, 투명 커버(242)는 집광부(230) 상부를 덮는 덮개부(240)에 형성된 홈에 삽입되는 형태로 고정 형성될 수가 있다. 이때, 투명 커버(242)의 출사면은 오목한 형상으로 형성될 수가 있는데, 이는 빛이 방출되는 투명 커버(242)의 출사면이 외부에 노출되어 충격 또는 스크래치 등에 의한 손상을 방지하도록 하기 위함이다. As shown in FIG. 3, a transparent cover 242 formed of a transparent material may be formed on the light collecting unit 230. The transparent cover 242 is irradiated from the light source unit 220 to collect the light collecting unit 230. Allow rough light to pass through. In this case, the transparent cover 242 may be fixedly formed in a shape that is inserted into a groove formed in the cover part 240 covering the light collecting part 230. At this time, the exit surface of the transparent cover 242 may be formed in a concave shape, in order to prevent the damage caused by impact or scratches is exposed to the outside of the exit surface of the transparent cover 242 is emitted light.

As shown in FIG. 5A, when the condenser 230 is not formed, the irradiated light spreads upward at a wide angle, and some of the light is reflected from the upper cover part 240 to be opposite. Part of the light emitted from the light source unit 220 is lost. In addition, since light emitted from the unit display module is widely spread and irradiated to the outside, a portion overlapping with light emitted from a neighboring display module may occur. On the other hand, as shown in the present invention, if the condenser 230 is formed to reflect the light emitted from the light source unit 220 to focus toward the upper cover portion 240 as shown in FIG. The amount of light reflected and lost from the light is reduced, and the interference between light irradiated from neighboring display modules is also reduced.

FIG. 6 illustrates an actual display module 200 when the control unit is configured to display an arrow using a display module 200 in which a part of the light collecting part 230 is formed and a part of the light collecting part 230 is not formed, according to the present invention. As shown in the enlarged photograph, the photoconcentrator 230 is applied to a portion to which the condenser 230 is applied, and thus, a clearer display image can be realized by condensing and diverging without interference between light emitted from neighboring unit display modules. have.

In addition, in the present invention, a light diffusion layer (not shown) may be formed on the reflective surface of the light collecting unit 230. In this case, the light diffusing layer may be formed by a method of coating the light diffusing agent on the surface.
도 8에 도시되어 있는 것과 같이 반사면에 형성된 광 확산층은 광원부(220)로부터 조사된 빛을 전체적으로는 상부를 향하여 반사시키되 다양한 확산 각도로 반사시킬 수가 있다. As illustrated in FIG. 8, the light diffusion layer formed on the reflective surface may reflect light emitted from the light source unit 220 as a whole toward the top, but may be reflected at various diffusion angles.
도 9는 소정의 각도로 입사된 빛이 반사면을 통해 반사될 때 광 확산층에 따른 반사 분포를 도시하는데, 도 9의 (a)에서는 광 확산층에 의해 확산 각도가 상대적으로 작은 경우를 도 9의 (b)에서는 광 확산층에 의해 확산 각도가 상대적으로 큰 경우를 도시하고 있다. FIG. 9 illustrates a reflection distribution according to a light diffusion layer when light incident at a predetermined angle is reflected through a reflection surface. In FIG. 9A, the diffusion angle of the light diffusion layer is relatively small in FIG. 9A. In (b), the case where the diffusion angle is relatively large by the light diffusion layer is shown.
이와 같이 반사면에 광 확산층을 다양하게 형성함으로써 소정의 각도로 조사된 빛을 다양한 각도의 범위로 확산시켜 반사시킬 수가 있다. As described above, by forming various light diffusion layers on the reflection surface, light irradiated at a predetermined angle can be diffused and reflected in a range of various angles.

As described above, when the light diffusion layer is formed on the reflective surface of the light converging unit 230 as described above, the light emitted from each light emitting diode may be dispersed and reflected at various angles, and thus different colors may be used. You can mix light evenly.
