[0009]

According to the first aspect of the present invention, asphalt and other lower-layer pavement portions are provided on a roadbed where the ground is solidified, and a dimming portion and a plurality of optical fiber tubes are previously loaded in the lower-layer pavement portions. One end of each of these optical fiber tubes is connected to the bottom of the light control unit, and the other end is converged and connected to the light source unit, so that light from the light source unit is diffused at the light control unit at the tip of the optical fiber tube. In the light control unit, in addition to diffusing light, light from a plurality of optical fiber tubes can be focused or mixed.

Since the transparent colored light emitting layer is provided above the light control section, light from the optical fiber diffused or focused passes through the glass pearl and is radiated onto the surface pavement layer.
The light emitted from the back side of the transparent light-emitting layer, such as glass pearl, onto the pavement surface shines, and in combination with these non-light-emitting layer parts without the light-emitting layer, creates images, figures, symbols or characters. Can be displayed to make it a fun square, and a continuous story with pictures can be displayed.

In the second aspect of the present invention, a plurality of glass spheres which are baked and colored as glass pearls are resin-bonded to each other to provide a columnar body or other transparent colored light emitting layer, so that the transparent light emission exhibits more powerful and beautiful color sensation. be able to.
In the third invention, by using a transparent light emitting layer made of synthetic resin pearls instead of glass pearls, a pair of pearl-shaped ones or a deformed one that can be easily molded can be used.

According to the fourth aspect of the present invention, the blinking operation of the transparent light emitting layer is controlled by a computer of the switching circuit of the light source section, so that the image and characters on the surface pavement layer blink continuously or intermittently. Can make the expression of the story and the alerting effect clearer. According to the fifth aspect of the invention, the switching circuit of the light source unit is controlled by the action of the pedestrian walking on the surface pavement layer through the use of infrared rays or other photodetection devices, so that there is a wide range of changes depending on the taste and action of the person. A blinking operation of the light is obtained.

In the sixth aspect of the invention, instead of the optical fiber tube, the light source section is directly installed on the bottom of the light control section, and a stronger light emitting action can be obtained.

m, a cylindrical body having a diameter of 50 mm.

The glass pearl referred to in the present invention is a glass sphere having a small sphere and a large number of pearls formed as described above to form a transparent light emitting layer. Stained glass pearls can be obtained by using a method of producing stained glass by baking for color development of glass balls. Not only the columnar shape, but also the shape as a component of characters and pictures according to the configuration of the surface pavement layer 8 can be freely selected.

The surface pavement layer 8 comprises the transparent colored light emitting layer 7 and the non-light emitting layer 9. The transparent colored light-emitting layer 7 and the non-light-emitting layer 9 design characters, images, patterns, and the like, and shine light on the transparent colored light-emitting layer 7 from the inner surface to radiate colorfully on the road surface. Perforated glass pearls such as glass marbles (marbles) and glass beads, and powdered glass pearls can be used as the glass pearls. . It may be colored or non-colored, but as the coloring method, not only simple coloring but also stained glass as baking coloring is used.

Marbles, beads and powders made of synthetic resin can also be used, and methyl methane, acrylic resin, styrene resin, polypropylene resin and other resins can be used. Further, when bonding glass pearls or pearls made of synthetic resin, a reactive resin (epoxy resin or the like), a thermoplastic resin (vinyl chloride resin or the like), an aqueous or emulsion type resin, or other resin can be used.

FIG. 2 shows an example of the transparent colored light-emitting layer 7 having a columnar shape.
It was a cylinder with a diameter of 7 cm and a diameter of 7 cm. When illuminated from below, diffuse reflection is repeated within the glass pearl, and beautiful, transparent light can be emitted to the surface side. FIG. 3 shows an example of the surface pavement layer 8 as a plaza for relaxation.

Although not shown, a surface paving layer 8 showing the progress of a moving image or a story is connected by a computer control to a light source unit 5 by connecting a light detecting device such as infrared rays according to the walking of a pedestrian on the promenade. Is easy to configure.

[0021]

According to the first aspect of the present invention, on the surface pavement portion, information can be easily provided by the transparent light due to the contrast between the transparent colored light emitting layer and the non-light emitting layer, and the alerting action by images and characters can be appropriately performed. It became as to be. In addition, the ground is solid, and the light emission can be easily adjusted by the light control section and the optical fiber tube pre-loaded in the lower pavement layer.
A pavement light emitting device with a wide range of applications was obtained.

In the second invention, the stained glass pearl is used as the glass pearl, so that the paved surface is more evident and more beautiful. In the third invention, it is easier to mold with a synthetic resin instead of glass pearl. According to the fourth aspect, the change of the surface pavement layer can be infinitely expanded by using the switching circuit of the light source unit.

According to the fifth aspect of the present invention, the light can be flickered as the pedestrian progresses, and the impression given to the user can be enhanced. In the sixth aspect, the light source section is directly provided on the light control section, which has the effect of making the brightness of light more apparent.
