The invention provides an illuminating fabric which can be driven by an external source, and has good compatibility between the illuminating device and the clothing, and can be designed into various illuminating effects. In addition, the actual contact of the human body is not required, and the light-emitting device in the light-emitting fabric can be activated according to the physiological state of the user or the change of the external environment. Please refer to FIG. 1 , which is a schematic diagram of an illuminating fabric that can be driven by an external source according to a preferred embodiment of the present invention. In Fig. 1, the components of the luminescent fabric 100 have a power source 105, a sensor 110, a light source actuator 12A, an illuminator 130, a fixture 140, and a light modifying fabric 150. The power source 105 is responsible for supplying the required power of the sensor 110, the light source actuator 12A, and the illuminator 130. The sensor u〇 senses the change of the external source, and sends a corresponding different sensing signal corresponding to the different changes of the external source to the light source actuator 120. After receiving the sensing signal 7 1320701, the light source actuator 12 generates a light source actuation signal corresponding to the sensing signal and transmits it to the illuminator 130. For example, the light source actuator 120 can convert the intensity or/and frequency of the sensed signal to have a light source actuation signal corresponding to the intensity or/or frequency of the sensed signal. The illuminant 130 will emit a corresponding light intensity and/or flicker frequency depending on the intensity of the light source actuation signal or/and the frequency.

The fixing device 140 is used to fix at least the illuminant 130 on the light-modifying fabric 150, and the light-modifying fabric 15 is modified to adjust the light emitted by the illuminating body 13 to have various effects. The fixture 14 can also be attached to the light modifying fabric together with the light source actuator 120 and the sensor 11 or to the garment to be placed on the luminescent fabric 100. The power source 105 described above is preferably a battery, and may be, for example, a mercury battery, a lithium battery, a polymer clock battery, a solar rechargeable battery, or any combination thereof.

The sensor 110 described above can be a mechanical switch, a light transducer, a sound transducer, a vibration transducer, or any combination thereof to receive various variations from the outside. For example, changes in the intensity of external light, changes in the intensity of sound, or vibrations, or even heartbeat, electrocardiogram, respiration, body temperature, blood pressure, or any combination of the above, can be sensed using a suitable sensor. It. The light source actuator 120 described above may be an actuator that is input with voltage or current. The illuminator 130 described above may be a point source, preferably a light emitting diode (LED). The fixing device 140 can be, for example, a rubber sleeve, an adhesive patch, a sewing thread or any combination thereof. For example, the power source 1 〇 5 'the light source actuator 12 〇 , 8 the illuminator 130 can be sealed in the rubber sleeve and reused. Adhesive sheets or stitches are attached to the enamel fabric 150. When the luminescent fabric 1 〇〇 is fixed to the laundry, it can also be washed with the laundry. The above-mentioned light-modifying fabric 15 is preferably a knitted fabric or a woven fabric which may be a single-layer fabric or a three-dimensional fabric, and the yarns used are general yarns, single fibers, metal yarns, and carbon black yarns. In the light-modifying effect, the general yarn has a scattering effect, the single fiber has a light-transmitting effect, the metal yarn has a reflection effect, and the carbon black yarn has a light-shielding effect. Therefore, the above four kinds of yarns can be combined to produce various light-modifying effects. Taking a single-layer woven fabric as an example, it is formed by interlacing two sets of yarns perpendicular to each other. The first set of yarns may be composed of a single fiber mixed with a general yarn, preferably consisting entirely of a single fiber to facilitate light passage through the fabric. The second set of yarns can be made up of a combination of the above-described general yarns, monofilaments, metal yarns, and carbon black yarns to produce various light-modifying effects. For example, if the second group of yarns only uses a general yarn, since the general yarn has the effect of scattering light, the light of the illuminator 130 is caused to have a soft halo effect. If the second set of yarns only uses metal yarns, the metal yarns have a light-reflecting effect, which causes the light of the illuminators 130 to produce a metallic luster. If only the carbon black yarn is used for the second group of yarns, since the carbon black yarn has a light-shielding effect, the light-emitting region of the illuminant 130 is irradiated onto the woven fabric to have a black line of straight lines. Of course, the second set of yarns can also be blended with the general yarns, monofilaments, metal yarns, and carbon black yarns described above to create a richer light finish. Since the distance between the single-layer light-modifying fabric 150 and the illuminator 130 is not large, the illuminating region of the illuminant 130 projected on the single-layer fabric is not too large. 4 The illuminating region on the glazing fabric (9) is increased. , can be achieved by using Li Zhao fabric. The Li Zhao fabric consists of a table cloth, a base fabric and a joint layer connecting the table cloth and the base cloth (4). The scale and the connecting yarn layer are preferably light transmissive, and the light path is increased to expand the light-emitting area of the light-modified fabric 150 t. Whereas the cloth portion 1 is a woven fabric, the surface fabric of the three-dimensional fabric can be woven by the variation of the single-layer fabric described above. For the detailed structure and weaving method of the knit fabric of the three-dimensional fabric, please refer to the contents of the "U.S. Patent No. 094,103, 401", "Transparent Fabrics and Manufacturing Methods Using Knitting and Weaving", which is the research and development result of the research unit. The following are some examples of possible variations in the second set of yarns in a single layer of fabric or a three-dimensional fabric woven from a woven fabric. In these examples, the weaving density of the 'group yarns is (10) / leaf 'the second group of yarns has a weaving density of 100 strips / 吋", Table 1: Symbol Description Symbol

As can be seen from Figures 2 and 3, the light modifying fabric 150 can modify the light emitted by the illuminator 130. In application, not only the effect of aesthetic change can be made, but different light-modifying fabrics 150 can be designed according to different kinds of external sources to generate different luminous effects. By allowing the user to look at it, it is possible to easily identify which external source changes and let the illuminator 13 illuminate. Further, the light-modifying fabric 150 may also be woven into the conductive fibers as a wire between the power source 105, the sensor 110, the light source actuator 120 and the illuminator 13A, in place of a general-purpose wire having a hard texture.

According to the above, it is known that a variety of yarns having different light-modifying effects are used to form a light-modifying fabric, and the light emitted from the illuminator can be variously changed. At the same time, a soft fixture is used to fix the combination of the sensor, the light source actuator and the illuminator on the light-modifying fabric. Even further, the soft conductive fiber is used on the light-repairing fabric to replace the generally harder one. A wire is used as a wire between the sensor, the light source actuator and the illuminator. Accordingly, the luminescent fabric provided by the preferred embodiment of the present invention provides considerable comfort and softness. In addition, various sensors can be combined to sense various changes in external light, sound and vibration, so it is very suitable for monitoring the physiological condition of the human body. The illuminating fabric provided by the preferred embodiment of the present invention can provide the utility of the warning effect in addition to the aesthetic effect. Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims. [Simple description of the map]
