[Problems to be Solved by the Invention] The neon tube of the neon tube signboard is a glass work made by a neon craftsman. Therefore, there is a limit in forming a complicated display pattern (advertisement pattern). In addition, although the neon tube emits light vividly, it is disadvantageous in that it causes the viewer to feel a dazzling glare, and it has a drawback that the fluffy impression rather reduces the advertising effect of the store.

Further, the neon tube signboard requires a transformer for generating a high voltage for lighting. Since this transformer installation work is extremely dangerous, there are restrictions on the installation location, and there are restrictions such as the need for a license for installation.

[0008] Further, neon tubes have many disadvantages such as generally short tube life and maintenance costs, large power consumption, and high maintenance costs.

The present invention solves the problems described above, consumes less power, has a low maintenance cost, and is capable of providing a clear and bright three-dimensional illuminated display that is easy on the eyes and facilitates the display of complicated display patterns.

Further, inside the signboard case body 4, a mounting plate 42 is erected on one side wall side, and a reflecting plate portion 43 is erected on the other side wall side facing the side wall. The mounting plate 42 includes a vertical portion 42a and a horizontal plate portion 42b that rise from the bottom plate portion 44.
And a printed wiring board is attached to the vertical portion 42a, and a plurality of full-color LED lamps 1 are formed.
Are arranged at regular intervals.

Further, as shown in FIG. 2, one side surface side of the surface light emitting body 2 closely faces and faces the full-color LED lamp 1, and the reflection plate portion 43 contacts the other side surface side of the surface light emitting body 2. There is. Reflector 43 and mounting plate (vertical 42a, horizontal 4)
2b) 42, for example, both of which are colored in white are used, and it is intended to prevent the loss of the projection amount of the full-color LED lamp 1.

Although not shown, the full-color LED 1 has a red light emitting LED chip, a blue light emitting LED chip, and a green light emitting LED chip mounted and arranged on a printed wiring board.

Further, a wiring substrate including the light emitting LED chip is resin-molded to form a light diffusing layer, and a cap-shaped lens portion is provided so as to open a predetermined space above the upper surface of the light diffusing layer. What is done is used.

The full-color LED 1 sequentially transmits light to three layers having different light refraction indexes and light reflection / diffusion rates, that is, a light diffusion portion, a space portion, and a lens portion, so that the light emitting elements of the respective light emitting elements can be transmitted. Sufficient emission brightness and perfect color mixing can be obtained.

As the surface light emitter 2, a transparent acrylic plate having a rectangular shape in a plan view and having a constant thickness is used. Within the entire area of the transparent acrylic plate, a large number of linear V-shaped grooves 21 are continuously arranged in parallel to each other in a direction perpendicular to the incident direction of light emitted from the side wall.

Therefore, when the light emitted from the full-color LED lamp 1 is incident from one side of the surface light emitter 2 and moves forward while reflecting in the plate, the surface of the plate (the bottom surface of the surface light emitter 2 in FIG. 2). 3 is diffused and refracted at the groove slope portion 21a of the V-shaped groove 21 provided on the upper surface of the surface light-emitting body 2 in FIG.

The translucent display pattern 3 has a surface,
Alternatively, each of the bottom surfaces may be set as a rough surface of light-diffusing pearskin texture (not shown). In this case, a more transparent (crystal) feeling, high brightness and clearness of the display can be obtained.

The translucent display pattern 3 is arranged on the surface of the surface light-emitting body 2 so as to be in continuous contact with it or in a superposed manner.
In the embodiment, the surfaces are fixed to the surface of the surface light emitter 2 in a polymerized manner. In this fixed state, each translucent display pattern 3 corresponds to each full-color LED lamp 1.
