[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 sheet and 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.

An example of applying the symbol display device to a road sign will be described with reference to FIGS. 6 to 9. The structure of the road sign shown in the front view of FIG. 6 and the side view of FIG. 7 has a white color on the sign board 21. 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. 8 is an explanatory view of the action of the road sign, and in the daytime, the sunlight is directly acting on the surface of the symbol 11 and the diffuse skylight 23 and the secondary scattered light 24 scatter the surface of the symbol. 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. 9 is a side cross-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 A are incident from the back of the design as shown in Fig. 8, there is a dazzling phenomenon and a decrease in the environmental illuminance ratio on the design surface, or a shade phenomenon, and the design is extremely high. The visibility and the attractiveness are bad, and in a remarkable case, the visibility of the design is impossible, and the phenomenon of no visibility or the attractiveness of the design occurs frequently in the daytime. It was a big problem and this was a big problem to be solved.

[0009]

[Means for Solving the Problems]

The recess 5 adjacent to every other one of the innumerable recesses 5 and 6 has a transparent or semitransparent white diffuser side 1 The Fresnel lens surface 5a is formed to focus and transmit the incident light on the surface side of the symbol display layer 7, and in the other concave portions 6 adjacent to every other one of the myriad concave portions, the concave portion 6 of the symbol display layer 7 is formed. Incident from the front side Is obtained is characterized in that the formation of the micro-prism surface 6a for reflecting Ri.

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 display layer 7 and the recesses 5 adjacent to every other one of the innumerable recesses 5 and 6 allow the light incident from the transparent or semitransparent white diffuser side 1 to the surface side of the pattern display layer 7. Free to focus and transmit The groove lens surface 5a is formed, and in the other concave portions 6 adjacent to every other one of the innumerable concave portions, the micro prism surface 6a for reflecting the light incident from the surface side of the pattern display layer 7 is formed. It is characterized by.

[0011]

[Action]

 Due to the above-described high-brightness pattern light emitting display 8, direct sunlight and diffuse skylight A received on the back surface of the transparent or semi-transparent white diffuser plate 1 are transparent to the transparent or semi-transparent white diffuser plate 1. The adhesive layer 3 and the transparent film layer 4 are transmitted, and further the Fresnel lens surface 5a of the concave portion 5 formed on the back surface of the pattern display layer 7 is focused and transmitted, and the pattern displayed on the surface of the pattern display layer 7 is enhanced. Brightness makes the visibility and attractiveness of the pattern extremely high during the daytime, especially during backlighting. 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.

By acting as described above, it is possible to produce an effect that reverses the state of deterioration of the visibility of the pattern at the time of backlighting in the daytime to the state where the visibility and the attractiveness are extremely high. It is possible to provide a high-intensity pattern light-emitting display that can always clearly display a pattern during the period.
