[Detailed description of the device]

[0001]

[Industrial applications]

 The idea is to direct the sun direct light and diffuse sky light received from the back of the design displayed on the surface light emitting plate to the design surface and to emit light with high brightness even higher than the sky. In a state where visibility is poor when backlit due to objects or terrain, extremely high visibility and attractiveness of patterns can be obtained.Therefore, road sign boards, line-of-sight guidance indicators, railway sign boards, harbor related indicators, The present invention relates to a high-intensity pattern light-emitting display that can be used for general signboards, indoor window displays, etc.

[0002]

[Prior art]

 The conventional pattern display device (non-illuminated pattern display device) ensures visual recognition of the pattern in the daytime by scattering or absorption by direct sunlight and diffuse skylight, secondary scattered light from buildings, road surfaces, trees, etc. In order to obtain visibility and attractiveness at night, diffused light from street lights and buildings, headlight light of vehicles, or external lighting is provided at night. .

In addition, the internal illumination symbol display device (internal illumination type symbol display device) ensures visibility of the symbol in the daytime as in the case of the non-illuminated symbol display device, and turns on the internal illumination at night. As a result, the design was made to emit light to be visually recognized.

As an example in which the symbol display device is applied to a road sign, it will be described with reference to FIGS. 5 to 8. The structure of the road sign shown in the front view of FIG. 5 and the side view of FIG. The pattern 11 is formed on the reflective sheet 22 by a transparent colored ink, a non-transparent colored ink, or a combination of a colored reflective sheet and a colored non-reflective sheet.

FIG. 7 is an explanatory view of the action of the road sign, and in the daytime, the direct sunlight of the sun, the diffuse skylight 23, and the secondary scattered light 24 which directly act on the surface of the symbol 11 scatter the symbol surface. Light emission or absorption was used to obtain visibility and attractiveness, and at night, visibility and attractiveness were obtained by the recursive reflected light from the headlight light B of the vehicle.

FIG. 8 is a side sectional view showing the structure of a road sign having internal lighting. A pattern print 29 is applied to the back surface of a face plate 28 made of a white diffusion plate attached to the front end opening of the housing 25, and at night, In order to make the design emit light, a fluorescent lamp 26 or an EL element plate 27 for electroluminescence is provided inside the housing 25 so that the design emits light and has visibility and attractiveness in the daytime. And the attractiveness is the same as the non-illuminated reflective sign.

[0007]

[Problems to be solved by the device]

 However, in the case of the conventional technology, the visibility and attractiveness of the pattern are secured by hitting the white reflective sheet with the headlight at night or by illuminating the pattern with internal lighting and external lighting. However, in the daytime, the visibility and attractiveness of the design is that the illuminance of the design on the vertical plane changes greatly depending on the light distribution direction of the diffused light in the sky including direct sunlight and the light distribution direction depending on the installation environment depending on the building and terrain. It is to be.

[0008] In particular, when the sun direct light and the sky diffused light are incident from the back surface of the pattern as shown in A in Fig. 8, a dazzling phenomenon and a decrease in the environmental illuminance ratio of the pattern surface and a shade phenomenon are caused, The visibility and the attractiveness of the design are extremely poor, and in a remarkable case, the visibility of the design becomes impossible, and the phenomenon of no visibility or the attractiveness of the design occurs frequently in the daytime. That was a big problem, and this was a big problem to be solved.

[0009]

Of the symbol display layer 7 It is obtained by a high-luminance pattern light emitting display sheet 2, characterized in that it forms the shape of the micro-prism surface 6a for reflecting light incident from the side.

A high-intensity symbol light-emitting display for uniformly emitting high-intensity light on the symbol surface opposite to the incident light surface of the direct sunlight and diffuse skylight received on the rear surface of the symbol, which is transparent or semi-transparent. It comprises a transparent white diffuser plate 1 and a high-intensity pattern light-emitting display sheet 2 joined to the transparent or semi-transparent white light diffuser plate 1. The high-intensity pattern light-emitting display sheet 2 is the transparent or semi-transparent white light diffuser plate 1. A transparent adhesive layer 3, a transparent film layer 4, and innumerable recesses 5 and 6 having a desired shape are formed on the back surface to be joined to the transparent film layer 4, and a pattern is displayed on the surface. The light incident from the transparent or semitransparent white diffuser side 1 is formed in the recess 5 adjacent to every other one of the innumerable recesses 5 and 6 formed on the back surface of the pattern display layer 7 by the display layer 7. Of the symbol display layer 7 A convex lens 5a that converges and transmits on the surface side is formed, and in the other concave portions 6 adjacent to every other one of the innumerable concave portions, a micro prism surface that reflects light incident from the surface side of the symbol display layer 7 is formed. 6a is a high-luminance pattern light-emitting display characterized by being formed.

[0011]

[Action]

 By using the high-intensity pattern light-emitting display sheet and the high-intensity pattern light-emitting display body as described above, the direct sunlight and the diffuse skylight A received on the back surface of the transparent or translucent white diffuser plate 1 are transparent or translucent. The light is transmitted through the white diffuser plate 1, the transparent adhesive layer 3, and the transparent film layer 4, and the convex lens 5a of the concave portion 5 formed on the back surface of the pattern display layer 7 is focused and transmitted, and is displayed on the surface of the pattern display layer 7. The design is made to emit high-intensity light, and the visibility and attractiveness of the design become extremely high during the daytime, especially when it is backlit. On the other hand, when the automobile headlight B is incident on the surface of the symbol display layer 7 at night, it is reflected by the microprism surface 6a of the concave portion 6 formed on the back surface of the symbol display layer 7 and displayed on the surface of the symbol display layer 7. By making the designed pattern emit light with high brightness, the visibility and attractiveness of the pattern at night become extremely high.
