Description

RELATED APPLICATIONS

The present application is based on, and claims priority from, Taiwan Application Serial Number 93113702, filed May 14, 2004, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Field of Invention
The present invention relates to a type of fabric, particularly to a type of illuminative fabric consisting of bright thread and light guiding fibers.
2. Description of Related Art
There are two lighting systems for nighttime illumination, decorative or warning systems. One is a passive, light-reflective device reflecting foreign light source for warning purposes without consuming power. Generally, the passive light-reflecting device consists of plastic light-reflective strips or light-reflective plates. These, however are made of hard materials, and do not provide light when no light source is available from the ambient environment.
Another system is an active light-emitting device made of fluorescent light or lamp bulbs, in most cases. Such device has a high luminosity and is free from environmental restrictions, but is not suitable for use on garments or decorations for warning or decorative purposes, because it has sophisticated construction and is bulky and expensive.
The conventional side-light fibers are made by partially destroying the coating of carbon fluoride molecules on the walls of regular plastic optical fibers. When a light source is provided at the end of a fiber, the light travels along the axis of the light guiding fiber. Since the reflective materials on the walls of the light guiding fibers are partially destroyed, light is emitted from the destroyed parts, thereby emitting light rays from the sides of the light guiding fibers. But the side-light fibers do not have sufficient flexibility and consistent lighting distribution, and do not allow sufficient curvature. Therefore, there is a need for a type of fabric with active illumination, which is lightweight, flexible and capable of providing consistent lighting effects, and can be used on clothing, decorations, bulletin boards and other devices.

SUMMARY

It is therefore an objective of the present invention to provide a type of fabric with active illumination and reflection characteristics. The fabric of the present invention is capable of providing active illumination at a location where sufficient lighting is lacking, and providing concentrated lighting by light reflection characteristics.
It is another an objective of the present invention to provide a lightweight, flexible and portable fabric with active illumination and passive reflection characteristics for the production of clothing, decorative articles, bulletin boards, and warning devices.
In accordance with the foregoing and other objectives of the present invention, a fabric is provided by interworking warp bright threads and weft light guiding fibers, the warp and the weft being interwoven in lengthwise and crosswise directions, or partial lengths of the weft light guiding fibers not being interwoven with the warp threads
The type of fabric provided to serve the purposes of the invention uses bright threads as the warp, and simultaneously the bright threads and light guiding fibers as the weft. Proportions of the bright threads and the light guiding fibers are chosen so the bright threads are intermittently arranged between the light guiding fibers. Then, the warp of bright threads and light guiding fibers is interwoven with the weft of bright threads, or partial lengths of the weft light guiding fibers not interwoven with the bright threads of the warp.
Optionally, the light guiding fibers used in the present invention of fabric are light guiding fibers with light escaping from their sidewalls. Additionally, the light guiding fibers of the weft are optionally connected with a light source, such as a Light-emitting Diode LED. One to seven pieces of light guiding fibers are optionally bundled as one and connected with the light source, or preferably, three to five pieces are bundled as one and connected with the light source.
The bright threads used in the present invention of fabric are optionally bright threads with a round, square or triangular cross section. The luminosity of the bright threads ranges from grade 1 to grade 10, and preferably between grade 5 and grade 10. The ratio of the light guiding fibers to the bright threads of the weft (light guiding fibers:bright threads) ranges from approximately 20:0 to 1:7, and preferably between 20:0 and 1:5, where 20:0 indicates that the weft consists fully of light guiding fibers.
The fabric with active illumination and reflection characteristics of the present invention uses weft light guiding fibers connected with light sources to provide active lighting, as well as light reflecting bright threads, the bright threads themselves and the plane composed of interwoven bright threads serving to reflect a foreign light source, and meanwhile reflecting the light projected from the light guiding fibers, causing the light to concentrate on a same side to achieve the purpose of concentrated and consistent lighting distribution. On the other hand, the present invention uses bright threads inserted between the light guiding fibers in the weft for lightness and flexibility.

Table 1 shows the following. First, high-luminosity bright threads as the materials are used for the woven fabric, providing higher luminosity to the woven fabric than the use of low-luminosity bright threads. For example, when only light guiding fibers are used for the weft, a woven fabric having a luminosity of grade 7 for the warp has a higher luminosity than a woven fabric having a luminosity of grade 5, and a third-grade woven fabric has a higher luminosity than a first-grade woven fabric. There is no need of proof to draw to the conclusion. When the threads have no light-reflecting effect (frosted threads) are used as the material for the woven fabric, the bright threads used as materials for the present invention will significantly increase the luminosity of the fabric.
Second, the cross-sectional shape of the bright threads has an effect. As shown in Table 1, given the same rate of light guiding fibers and bright threads in the weft, a woven fabric using triangular bright threads has a higher luminosity than a fabric using round threads. Because triangular bright threads have planes that are more efficient in reflecting light, given the same proportion of use of light guiding fibers for the weft, triangular bright threads are capable of a higher luminosity than round bright threads. Meanwhile, bright threads having a square cross section are also capable of increasing the light-reflecting efficiency of woven fabrics, thereby increasing the luminosity of the woven fabrics.
Thirdth, the proportions of light guiding fibers and bright threads used for the weft are also important. When a higher percentage of light guiding fibers is used, the woven fabric will have a higher luminosity. Relatively, when the weft uses a higher percentage of bright threads, the woven fabric will have a lighter and softer texture, while the plane interwoven of bright threads (such as the plane 308 in FIG. 3) and the bright threads themselves will provide an active and consistent light source, and will reflect the light coming from a foreign source. The rate of light guiding fibers and bright threads used for the weft may range from 20:0 to about 1:7, or preferably between 20:0 and about 1:5.
Therefore, the present invention provides a woven fabric using light guiding fibers as materials, with a light-emitting source connected to the terminals of the light guiding fibers, providing active illumination to the woven fabric of the present invention. Another feature of the present invention is the use of bright threads in the fabric, using the plane composed of interwoven bright threads to reflect the light coming from a foreign source, and meanwhile reflecting the light emitted from the light guiding fibers, so the light is concentrated on the same side and has a consistent light distribution. On the other hand, bright threads are inserted between the light guiding fibers in the weft, allow the present invention of an illuminated fabric to be lightweight and flexible.
Moreover, the percentage of light guiding fibers and the types of bright threads can be adjusted to suit the needs of applications of the present invention. For instance, when the invention of illuminating fabric is used on an warning signal, it is advisable to use only light guiding fibers for the weft, and triangular or square bright threads having a luminosity of grade ten, in order to produce a woven fabric having the highest luminosity for warning purposes. Also, when the present invention is used on clothing or decorative items, it is advisable to insert a specified number of bright threads between the light guiding fibers for the weft, to increase the flexibility of the woven fabric, and provide better comfort and lighting effects.
The specific percentages and figures cited in the foregoing embodiments, including luminosity grade 5 and rate 1:7, and directional indications such as “upper part” and “lower part”, are used merely for the purpose of representation, which shall not be used to restrict the scope of the present invention. The foregoing demonstration or description of the preferred embodiments has been provided for reference only. It is to be understood that all modifications and equivalent variations in details or configurations made by anyone skilled in the art according to the principles disclosed above shall be included in the spirit and intent of the present invention.
