Description

Luminous fabric

The novel creation relates to a fabric, and in particular to a luminescent fabric.

As the economy accelerates globalization, the textile industry faces strong transformation and competitive pressures, so it is necessary to continuously upgrade textile technology and develop high-value products. In recent years, due to the booming optoelectronic industry, some optoelectronic components (such as light-emitting diodes) have gradually been applied to fabrics, so that the fabrics have the function of illuminating or even displaying. A number of luminescent fabric designs have been proposed in succession.

However, in the luminescent fabrics proposed by these prior art, the carrier for carrying the illuminating source is generally not permeable, and if the carrier is directly in contact with the human body, it may cause skin irritation and the like. In addition, since the light source in the luminescent fabric is mostly a point light source, and the color of the light that can be presented is usually only the color of the light source itself, the light color of the conventional luminescent fabric can be monotonous and lacks variability. There is a need for improvement.

Moreover, existing luminescent fabrics are limited by the source of power and consume energy and have limited effectiveness. For example, a passive illuminating yarn can be made by adding a power source. Light, so its luminous efficiency will gradually decrease as the power supply weakens, and the active illuminating yarn can only illuminate in the bright place of the environment before it can emit light in the dark place. Regardless of the above-mentioned luminescent fabric, it is limited by external conditions or its own characteristics.

The novel creation provides a luminescent fabric that combines an active illuminating yarn with a passive illuminating yarn to achieve a light mixing and energy saving effect.

The novel illuminating fabrics include passive illuminating yarns and active illuminating yarns. The active illuminating yarn is interwoven with the passive illuminating yarn, or the passive illuminating yarn is surrounded by the active illuminating yarn.

In an embodiment of the present invention, a power source is further included, and the passive illuminating yarn is electrically connected to generate the first ray of the passive illuminating yarn.

In an embodiment of the present invention, the active illuminating yarn absorbs the second ray to generate a third ray, and the wavelength range of the first ray is covered in the wavelength range of the second ray.

In an embodiment of the present invention, the wavelength range of the second ray is at least partially overlapped with the wavelength range of the third ray.

In an embodiment of the present invention, the wavelength range of the second light and the wavelength range of the third light do not overlap each other.

In an embodiment of the present invention, the wavelength range of the first light is different from the wavelength range of the third light, and the first light and the third light are mixed into a fourth Light.

In an embodiment of the present invention, each of the passive illuminating yarns includes at least one light emitting diode and two or more conductive yarns. The light emitting diode has two or more electrodes. The conductive yarn is electrically connected to the power source, and each of the conductive yarns is electrically connected to one of the electrodes, and each of the conductive yarns is electrically insulated from each other.

In an embodiment of the present invention, each of the light emitting diodes includes at least one light emitting diode chip and at least one encapsulant. The light emitting diode wafer has the above electrodes. The encapsulant encapsulates at least one of the light emitting diode wafers and a partial region of the conductive yarn.

In an embodiment of the novel creation, the illuminating fabric described above forms at least a partial petal structure of a flower.

In an embodiment of the novel creation, the illuminating fabric described above forms at least a portion of a decorative strip.

Based on the above, in the above embodiment of the novel, the illuminating fabric is interwoven with the active illuminating yarn and the passive illuminating yarn, or the passive illuminating yarn is surrounded by the active illuminating yarn to allow the two It can be effectively combined, wherein the passive illuminating yarn generates a first ray, and the active illuminating yarn absorbs the second ray to generate a third ray, and the wavelength range of the first ray is covered in the wavelength range of the second ray. Therefore, the light-emitting fabric emits light while driving the passive light-emitting yarn, and the light generated by the light-emitting fabric can also absorb the active light-emitting yarn to achieve the light-storing effect. When the illuminating fabric is no longer driven by the power source to drive the passive illuminating yarn, and the illuminating fabric is in a dark environment, the active illuminating yarn can thereby produce a third The light reaches the effect of illuminating. In other words, the illuminating fabric can achieve an energy-saving effect by interlacing the active illuminating yarn and the passive illuminating yarn.

Furthermore, the active illuminating yarn 200 is configured to absorb the second ray to generate a third ray, and the wavelength range of the first ray is covered in the wavelength range of the second ray. Therefore, the first light generated by the passive illuminating yarn 100 can also serve as a light storage source for the active illuminating yarn 200.

For example, the passive illuminating yarn 100 of the present embodiment generates a first light having a wavelength in the range of 300 nm to 800 nm, and a preferred range thereof is 300 nm to 400 nm or 476 nm to 570 nm (depending on the type of the light emitting diode) The wavelength range in which the active luminescent yarn 200 is absorbed includes the spectral range of sunlight, and preferably 300 nm to 570 nm (depending on the type of the raw material thereof), and the third generated by the active luminescent fiber 200 The wavelength of the light is in the range of 400 nm to 800 nm. On the other hand, when the passive illuminating yarn 100 and the active hair When the optical yarns 200 are simultaneously illuminated, the first light and the third light respectively generated in different wavelength ranges can also form a fourth light, wherein the fourth light is a mixed color light of the first light and the third light. In other words, the active illuminating yarn 200 is not limited to be able to emit light in a dark environment, so that the first ray and the third ray generated by the active illuminating yarn 200 and the passive illuminating yarn 100 are mixed. Light effect. For example, the first ray generated by the passive illuminating yarn 100 ranges from 624 nm to 640 nm, and the third ray generated by the active illuminating yarn 200 ranges from 470 nm to 490 nm, and the fourth ray is mixed. The wavelength range is from 600 nm to 620 nm. Accordingly, the designer can adjust the relevant specifications of the active illuminating yarn 200 and the passive illuminating yarn 100 according to the use requirements to obtain the wavelength range of the desired light.
