Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a striated body that emits light at night or in a dark atmosphere, and is used as a safety fence, fishing gear, animal repellent fence, decoration device, appreciation device, antitheft device for various articles, and rescue device. The present invention relates to a high-luminance luminous filament used as a component or an accessory of such articles in a wide range of applications such as.

[0002]

2. Description of the Related Art Hitherto, as a component or accessory of various articles in the above-described various regions, a flexible rope body or a striated flexible / rigid elongated member has been widely used.

[0003]

However, since the conventional striated body has no self-luminous property, it has a dark atmosphere, for example, as a safety fence in a danger area or a construction site, or as a component of fishing gear and fishing gear used at night. When used in such a location, fences, tools, etc., may cause insecurity and inconvenience due to difficulty in visual recognition, and utility model registration No. 3024157 with locking members at both ends of the striatum. The "wire lock / bicycle lock" disclosed in Japanese Utility Model Application Laid-Open No. 63-201174 is difficult to visually recognize in the dark, making it difficult to unlock at night. Then use it (a little borrowing)
There is a problem that triggers seizures and burglary.

Further, even in a conventional decorative device such as an illumination using a striated body, since the striated body itself does not emit light, an extremely large number of illuminated lamps must be connected to the striated body. In addition, the decorative effect is made uniform and the setting of the decorative device requires a great deal of trouble, resulting in an increase in cost.

[0005] On the other hand, if a wild animal intrusion prevention fence is set with a conventional striatum in order to protect crops produced by wild animals traveling at night, there are cases where the fences are easily destroyed and invaded. An object of the present invention is to provide a high-luminance light-emitting striated body that solves the above-mentioned disadvantages of the related art and enables development of a new application of the striated body.

[0006]

In order to solve the above-mentioned technical problems, the high-luminance luminous filament of the present invention comprises a "surface layer made of a material having a high reflectivity of visible light, or a white surface layer having a high reflectivity of visible light. And a phosphorescent layer containing a phosphorescent agent that embeds the core material is provided on a linear core material having the following structure.

That is, the high-luminance luminous filament of the present invention stores the sunlight and illumination light received by the luminous layer and emits light from the outer periphery in the longitudinal direction of the luminous filament. Thus, a feature of the structure is that the light emitted in the direction of the core among the light emission is reflected, and high-luminance light can be radiated from the outer periphery.

[0008] The core material may be formed entirely of an aluminum material, a silver material, or the like having the above-mentioned surface layer requirements, or may be provided with a surface treatment or a core material of any soft or hard material. It is formed by adding a surface layer of the above requirements by a known means such as “plating treatment, metal deposition, metal foil winding, paint application”. The phosphorescent light-emitting layer is formed of a known phosphorescent substance using an alkaline earth aluminate as a host crystal.
Alternatively, it is configured such that fine particles of a “phosphorescent light emitting agent of a sulfide phosphor” are contained in a transparent or light transmitting resin.

The striatum according to the present invention has a linear cross-sectional shape of a circle, an ellipse, an oval, or a polygon.
It means a strip having an elongated band-like cross-section or other irregular cross-sections. The core material to be present inside the light-storing light emitting layer is arbitrarily selected from those having a similar shape or a non-similar shape to the above-mentioned striated body shape, is set to one or more, and is embedded in the light-storing light emitting layer.

[0010]

When the high-luminance light-emitting striation of the present invention having the above-mentioned structure receives sunlight or nighttime illumination light, the received light enters the light-storing light-emitting layer containing the light-storing agent and is stored and radiated from the surface. Therefore, the striatum in a dark atmosphere such as at night becomes self-luminous and can be visually recognized, and functions as a "shining striatum". And
Since the core material surface layer of the above requirements exists inside the light-storing light-emitting layer, light emitted toward the center of the striatum is reflected by the surface layer toward the outer periphery of the striatum, and is combined with the original outer directional light emission. As a result, it is possible to self-emit high-brightness diffused light for a long time.

[0011]
