Definitions

  • the present invention relates to an enveloped electrical component in particular an electrical component provided with lighting components such as LEDs enveloped with a textile structure.
  • the invention also relates to a method of manufacturing such an enveloped electrical component.
  • the invention furthermore relates to a textile structure comprising at least one enveloped electrical component integrated in this textile structure and to a method of manufacturing such a textile structure.
  • Elongated elements such as wires, strips and cables provided with LED lights are well known and are for example used for home decoration or decoration for the holidays. Most of these elongated elements provided with LED lights are engineered so that they can be used as decoration. Because of this, these elongated elements have a limited mechanical performance.
  • Textiles and textile materials can be found in many different applications, ranging from clothing, interior decoration, curtains, wallcovering, bedding textiles, etcetera. Although textile materials can be widely found, they normally don't incorporate lighting in their use. As textile materials have to be able to be washed, have to be flexible, have to be drapable and have sometimes additional necessary features such as stitchability it is difficult to provide textile materials incorporating lighting. Although it is difficult to incorporate lighting in textile materials, it is a function that is definitely wanted to decorate or accentuate issues.
  • Ribbons are typically thin bands of material, typically made of textile fibers. They are used primarily as decorative materials onto other textile materials or objects. Ribbons can for example be woven, knitted or braided. Many different types of textile fibers such as cotton, silk, polyester or polyamide fibers are used for producing ribbons.
  • US20150204496 discloses a fabric construction having woven tubular hollows with light emitting means mounted in the tubular hollows of the fabric construction.
  • GB2396252 discloses a fabric with LED components mounted or stitched onto the fabric. These LED components are visually present onto the fabric.
  • WO200880245 discloses a LED light wire that is protected through winding a textile yarn over the LED light wire. The thus obtained yarn can then be further used as a warp or weft yarn in a fabric.
  • an enveloped electrical component comprises an electrical component and an envelopment surrounding said electrical component.
  • the envelopment comprises a textile structure.
  • the textile structure is provided around the electrical component by a textile operation.
  • the envelopment is in direct contact with the electrical component.

  • the envelopment fully covers the electrical component so that the electrical component is invisible for the human eye.
  • the term 'electrical component' refers to any type of electrically conductive material, preferably elongated electrically conductive material, such as wires, metal wires, strips, metal strips, ribbons, or other conductive elongated elements.

Because of the direct contact between the electrical component and the envelopment it can be physically hard to pull the electrical component out of the textile structure. Such envelopment allows to process the electrical component into a textile structure without damaging the electrical component. Furthermore, the envelopment makes the electrical component invisible for the human eye, so that it has a high decorative aspect.
