Abstract

PURPOSE: To determine the linearity of a road fence easily, and to improve a sight-line guidance effect, a production effect and decorative properties by fitting an illuminant along a handrail or/and a cross beam and mounting a light source guiding light and light-emitting or flickering the illuminant. CONSTITUTION: Electricity is supplied from a power supply device, and light from a light source 3 is controlled by a controller 5 and light-emitted and flickered. The light is passed through a color filter 6, and projected from one end of the core of a tubular illuminant 2a. Incident light is reflected by the boundary surface of a flexible tube and the core. A part is emitted from an outer circumferential surface while incident light is transmitted to the other end of the core by repeating the reflection, thus emitting light uniformly linearly and extremely efficiently. Several kinds of the properly prepared color filters 6 are controlled, thus changing a luminescent color at every fixed time. Another optical transmission means is interposed between the light source 3 and the tubular illuminant 2a, and light is guided to the tubular illuminant 2a.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a road, a bridge, a footbridge,
It concerns road fences installed along parks, station squares, promenades or other roads.

[0002]

[Prior Art] Roads, bridges, pedestrian bridges, parks, station squares,
As a road fence installed along a promenade or other roads, for example, as described in Japanese Utility Model Publication No. 5-29204, an illumination lamp is provided at the opening on the lower corner side of the road of the top rail that constitutes the road fence. There is a balustrade with lighting that is installed and illuminated by this lighting on the road surface.

[0003]

However, the above-mentioned balustrade with an illumination light is intended to ensure traffic safety at night by illuminating the road surface with the illumination light, but the illumination light is a road fence. Since it did not directly irradiate itself, at nighttime, the road fence itself was dark and difficult to see, and the line-of-sight guidance effect was poor. In addition, recently, the cityscape at night is also emphasized, and the effect and decoration of the night are also required. There was also a lack of decorativeness.

Therefore, the present invention solves the above problems,
Particularly, at night and the like, the present invention intends to provide a road fence that enhances the line-of-sight guiding effect and enhances the effect and decorativeness.

[0005]

In order to achieve the above object, the present invention has the following constitution. That is, the road fence according to the present invention is provided with a luminous body which is attached along a handrail or / and a lateral beam and emits linear light, and a light source which guides the luminous body to emit or blink the luminous body. It is characterized by having.

A halogen lamp, a metal halogen lamp, a xenon lamp, a high-intensity discharge lamp, a light emitting diode, or the like is generally used as the light source, and the light source is not particularly limited. Further, the power supply device for making these light sources emit light may be a solar cell or a commercial power supply.

The luminous body may be attached to the outer peripheral surface of the handrail or the horizontal beam with a band metal fitting or the like. However, a groove is formed along the longitudinal direction of the handrail or the horizontal beam, and the light emitting body is fitted into the groove. If these are installed, these handrails, horizontal beams, and light emitters can be easily integrated, and no extra band metal fittings or screws are required, resulting in a neat appearance and easy installation. Is also excellent.

The type of the luminous body is not particularly limited as long as it is mounted along the handrail or / and the lateral beam and emits light linearly by emitting the light guided from the light source. However, it is preferably composed of a long tube-shaped light emitter including a flexible tube and a core housed in the flexible tube and having a higher refractive index than the flexible tube. According to this tube-shaped light emitter, compared to other illumination lamps, no electric wiring is required,
Compared to the optical fiber, which has excellent water resistance, is easy to maintain, and does not emit light from the outer peripheral surface, the light incident on one end of the core from the light source is reflected at the boundary surface between the flexible tube and the core, By repeating this reflection, a part of the light is emitted from the outer peripheral surface while being transmitted to the other end of the core, so that the light is emitted uniformly and linearly. Moreover, since the tube-shaped light emitter can be made thicker (outer diameter is about 5 to 20 mm) incomparable to the optical fiber, a large amount of light is made incident and the amount of light emitted from the outer peripheral surface is increased. Therefore, the emission brightness can be increased. Furthermore, since this tube-shaped light emitter can be easily bent, it can be easily attached even to handrails or lateral beams that are curved along the road, etc., and by using a color filter, the emission color can be changed. It can be changed, and it is possible to create a production that matches the landscape.

If the flexible tube is made of a light-transmitting material, the light is emitted from the entire outer peripheral surface. However, if the flexible tube is made of a light-shielding material and a light leak part is partially formed,
Alternatively, the outer peripheral surface of the flexible tube made of a light-transmitting material is covered with a light-shielding material, and the light-shielding material is partially cut out to form a light leakage portion so that the light is emitted in a dot line shape. Alternatively, a part of the flexible tube made of a light-transmitting material may be covered with a light-shielding material along the longitudinal direction so that light is not emitted from the entire outer peripheral surface and faces a passing vehicle or person. The light may be emitted only from the surface side.

The boundary surface where the core and the flexible tube are in contact with each other, that is, the inner wall surface of the flexible tube may be smooth, but if fine irregularities are formed, the incident light is irregular due to the fine irregularities. This is preferable because a large amount of light is reflected and emitted from the outer peripheral surface.

The material forming the flexible tube is not particularly limited as long as it is flexible and can be formed into a tube shape and has a low refractive index. Synthetic resins such as polyethylene, polypropylene, polyvinyl chloride, polyamide, polystyrene-butadiene copolymer, butyl rubber, EPDM, acrylonitrile-butadiene copolymer, fluororubber, silicone rubber, etc. are used, and silicone having a particularly low refractive index is used. Polymers and fluoropolymers are preferably used, and these materials may be used alone or in combination of two or more kinds, and may be a single layer or multiple layers.

The core is not particularly limited as long as it has a higher refractive index and a light transmitting property than the flexible tube, and a viscous liquid state, a solid state or a gel state is usually used. . Examples of the viscous liquid or gel core include polyols such as polyethylene oxide, polypropylene oxide and glycerin, polyol esters, polyol ethers, phosphoric acid esters such as chloroethyl phosphate, dichloropropyl phosphate, liquid paraffin and fluoro oil. , Silicone oil, polyisobutylene, polysiloxane-modified polyether, an aqueous solution of an inorganic salt, a polymer solution obtained by diluting a polymer with a suitable solvent, and the like, and a solid core such as polymethylmethacrylate.

When the core is in the form of a viscous liquid or gel, both ends of the flexible tube are made of a translucent material such as glass or quartz so as not to leak from the flexible tube. It is preferable that the solid core is accommodated in the flexible tube by inserting a monomer of synthetic resin into the flexible tube and polymerizing it in a properly shaped state. A preferable example of such a tubular luminous body is Ray Duck Light manufactured by Bridgestone Corporation.

The light-emitting body composed of the above-mentioned tube-shaped light-emitting body may be mounted as it is, but when the tube-shaped light-emitting body is fitted and mounted in the transparent long protective tube, the tube-shaped light-emitting body is mounted. Since it is not exposed to the outside and is protected by a transparent long protective tube, damage is prevented. The transparent long protective tube is not particularly limited in its cross-sectional shape as long as it has an insertion hole into which the tubular light-emitting body is inserted in the longitudinal direction, and may be divided into a plurality of pieces in the longitudinal direction. Good. The transparent long protective tube is generally formed of a hard material made of transparent resin such as colorless or colored light, synthetic resin such as polycarbonate or acrylic resin. Also, by covering a part of the transparent long protective tube with a light-shielding material, the light passing through the transparent long protective tube from the tubular light-emitting body is transmitted in a dot line shape, or is opposed to a vehicle or a person. You may make it permeate | transmit only from the surface side to do.

[0015]

Since the road fence according to the present invention is provided with a luminous body that emits a linear light or blinks along the handrail or / and the lateral beam, the alignment of the road fence can be improved especially at night. It becomes clear and easy to understand, and has excellent visual line guidance effects. Also, the luminous effect that flashes and blinks linearly enhances the effect of presentation and decoration. Further, since the light emitting body emits light by emitting light guided from the light source, the light emitting body itself does not require electrical wiring, and therefore has excellent water resistance even when wet with rainwater and is easy to maintain. is there.
