Description

luminous fabric

technical field

The utility model relates to an illuminating textile article, and in particular, the illuminating fabric according to the present utility model is a fabric integrating a light-emitting diode (light-emitting diode), and can be designed as a finished product according to requirements, and can also be used as another fabric. A weaving yarn for textiles.

Background technique

Light-emitting diodes have been widely used in indication, display, lighting and other purposes. Devices combined with light-emitting diodes have also gradually appeared on textiles (eg, clothing) from indicator lights, traffic signs, lamps, and street lights on electrical equipment in the past.

The existing method of combining light-emitting diodes to textiles is to join the light-emitting diodes to a flexible printed circuit board, and then attach the flexible printed circuit board with the light-emitting diodes to the textiles. Obviously, the flexible circuit board used in the above method has limited flexibility and should not be bent or pulled excessively. Therefore, in order to maintain a certain degree of flexibility in textiles, the above-mentioned methods mostly use small-sized flexible circuit boards. Even so, it is difficult to meet the requirements of textiles in terms of aesthetics and comfort, so it is difficult for consumers to accept them. Moreover, if the above method adopts a large-area flexible circuit board, the weight and thickness of the final textile will increase, and it will be difficult to integrate with the textile into an aesthetic design. In addition, if the above method needs to change the layout of the light emitting diodes, the flexible circuit board needs to be redesigned, which consumes time and cost. In addition, the above-mentioned method of using the flexible circuit board is a polluting process, which is not conducive to environmental protection.

Another method is to attach or fix the optical fiber or flexible light-conducting tube on the textile with light leakage on the surface, and the light emitted from the light-emitting diode comes from one end of the optical fiber or light-conducting tube. The light then leaks from the surface of the fiber or light guide. Because the material comfort and flexibility of the optical fiber are not good, and the connection between the light source and the textile is not easy, the practicability and processability are greatly limited. In addition, the above-mentioned method cannot achieve the effect of large-area light emission and the requirement of single light-emitting point control, and the brightness is low.
