Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-up structure for a road structure such as a soundproof wall, a translucent soundproof plate, a girder decorative plate for a bridge, which is illuminated or illuminated to make it stand out.

[0002]

2. Description of the Related Art Conventionally, a light-up structure for illuminating or illuminating a road structure to bring it up is disclosed in, for example, Japanese Utility Model Laid-Open No. 5-3318, which is a light-up structure for a road structure in which a lighting device is attached to a soundproof wall. As described, it is used to make various road structures look beautiful and to show their existence. Known structures for illuminating this road structure include an internal lighting structure in which a transparent plate is provided in front of a fluorescent lamp or an incandescent lamp, a structure in which optical fibers are embedded, and a structure in which a structure is illuminated by external lighting.

On the other hand, Japanese Unexamined Patent Publication No. 62-144102 describes a transparent plate having one surface having an uneven surface and the other surface having a smooth surface. This transparent plate is used as follows. That is, the transparent plate and the reflection plate are attached to each other with the uneven surface of the transparent plate facing inward at regular intervals, and a mirror is attached to one of the gaps between the transparent plate and the reflection plate to irradiate light from the opposite side. To do. Then, since the light is radiated substantially uniformly from the smooth surface of the transparent plate in the right-angle direction, the illumination efficiency is good and the illumination device is preferable. This transparent plate is often used as a surface light source for display devices using liquid crystals such as word processors and personal computers.

[0004]

However, since the internal lighting structure provided with the fluorescent lamp has a large number of light sources arranged on the irradiation surface, it is difficult to replace it when the light sources are cut off. The interior lighting structure with an incandescent lamp shines well near the incandescent lamp,
Since the distant part becomes dark, it is a problem as a light source for a structure. Further, since the structure for embedding the optical fiber is ugly when the terminal of the optical fiber is visible in the daytime, there is a problem that it is necessary to cover and hide the light source which is the terminal of the optical fiber with a colored plate. In addition, the external lighting structure has difficulty in installing the lighting device.

Therefore, the present inventor has provided a light source at the end portion such as an incandescent lamp which can be easily replaced, and moreover, the light emitted from the light source provided at the end portion such as the display device using the liquid crystal is substantially uniform. When the road structure is lighted up by the method of strongly irradiating from the irradiation surface in a direction substantially at right angles, it was found that the light source could be easily replaced and the efficiency of light was good, and the present invention was accomplished. That is, it is an object of the present invention to provide a light-up structure for a road structure in which the replacement of the light source is easy and the entire surface is illuminated almost uniformly and efficiently.

[0006]

The present invention has been made to achieve the above object, and the invention of claim 1 is a light for a road structure in which a light-up light source is attached to the road structure. In the light-up light source, the light-up light source has a light-diffusing emitter provided with a mirror for reflecting light inward at one end of a transparent cylindrical body having an uneven inner surface, and a transparent plate on a side surface. A light source which is inserted into a diffuser made of a cylindrical body whose inner surface on the opposite side is a reflecting surface and which irradiates light into the inside from the other end of the light diffuser is detachably attached.

A commercial power source may be used as the electric energy supplied to the light source. However, when the commercial power source is used, wiring such as an aerial cable and underground wiring work are required, which is troublesome and expensive. Therefore, it is convenient to use the solar cell as in the invention of claim 2. That is, the invention of claim 2 is a solar cell attached to the outer surface of the diffuser used in the invention of claim 1 other than the transparent plate, and a storage battery for charging the electrical energy generated by the solar cell. When the solar cell is generating power, the storage battery is charged with the electric energy generated by the solar cell, and when it becomes dark, the control unit supplies electric energy to the light source from the storage battery.

The transparent tubular body of the light diffusion emitter used in the present invention has an uneven surface on the inner surface. The unevenness provided on the uneven surface may be appropriate. For example, an uneven surface may be provided on the inner surface of the transparent body in the circumferential direction, or an uneven surface may be provided in the longitudinal direction. Moreover, you may provide an uneven | corrugated strip in the diagonal direction. or,
A plurality of protrusions protruding in a mountain shape may be provided on the inner surface to form the uneven surface.

[0009]

In the light-up structure of the road structure of the present invention, the light emitted from the light source illuminates the inside from the other end of the transparent cylinder. Then, as shown in FIG. 7, the light 101 emitted from the light source 100 toward the transparent plate 120 is transmitted to the transparent cylindrical body 110.
The light is refracted by the uneven surface 111 provided on the inner surface of the diffuser, and a large amount of light is emitted from the transparent plate 120 of the diffuser in a direction at a right angle. The light 102 emitted in the direction of the surface 122 opposite to the transparent plate 120 passes through the transparent cylindrical body 110 and the reflecting surface 12 of the diffuser.
It is reflected by 1 and again passes through the transparent cylindrical body 110, is refracted by the uneven surface 111, and is irradiated from the transparent plate 120 in a direction at a right angle. Light 103 emitted from the light source 100 toward one end of the transparent cylindrical body 110 is reflected by a mirror 140 provided at one end, irradiates the uneven surface 111 from the opposite side, and is refracted by the uneven surface 111.
A large amount of light is emitted from the transparent plate 120 in a direction forming a right angle.

As described above, the uneven surface 111 is formed from the light source 100.
By the light refracted by the light and the light refracted by the concave-convex surface 111 from the opposite side, a large amount of light is emitted from the transparent plate in a direction forming a right angle regardless of the distance of the light source, and the transparent plate becomes almost uniformly bright. As a result, as shown in A of FIG.
The intensity of the light emitted from the transparent plate 120 is strong in the direction perpendicular to the transparent plate 120, and becomes weaker toward the periphery, and almost no light is emitted along the transparent plate 120.
become. In this way, the light emitted from the transparent plate by the irregularities provided on the inner surface of the transparent cylindrical body of the light diffusion emitter and the mirror is converged in the direction perpendicular to the transparent plate, and as a result, the light-up light source is transparent. The plate 120 is efficiently irradiated in a direction at a right angle.

Further, in the present invention, since the light source is detachably attached to the end portion, it can be easily replaced when the light source fails. In the present invention, claim 2
As described above, when the electric energy generated by the solar cell is used as the power source, the commercial power source is not used, and thus wiring such as aerial cables and underground wiring work are unnecessary. Further, if a control unit for storing the electric energy generated by the solar cell in the storage battery and supplying the electric energy to the light source when it becomes dark is used only when the electric energy becomes dark, there is no waste of the electric energy.
