  • the present invention concerns the integration of fiber optics and LED lighting systems to create lit up optical fiber light installations, including but not limited to optical fiber textiles.
  • Technical Background Existing methods for integrating light sources with fiber optics are often complex and require specially manufactured components. These methods lead to high production costs and difficulties in maintenance and repairs.
  • One aim of the present invention is to provide a system and method for improving the integration of LED lighting and fiber optics.
  • a system intended for integration of LED lighting in fiber optic light installations in optical fiber textiles comprising - a LED strip; - multiple connection units, wherein a connection unit comprises: - an upper connection part having one connection end arranged to be fixated to the lower connection unit, said upper connection unit comprising an open end with a tube unit arranged for including fixated fiber optic threads arranged to be connected to the LED strip; and - a lower connection unit arranged to be fastened around the LED strip, preferably clipping on to the upper connection, wherein the LED strip comprises LEDs intended to match the connection ends of the upper connection parts, where said LEDs are an extended geometry possible to fixate into a matching open geometry of the connection ends.
  • the present invention relates to a flexible system and method for improving the integration of LED lighting in fiber optic textiles.
  • the system uses two flexible plastic connectors that allow quick and easy connection of a variety of standardized LED strips to fiber optic threads, promoting modular use and maintenance.

  • One example is shown in fig.1.
  • the lower connection unit is a clip which may be arranged around the LED strip and to fixate the upper connection part being clicked into the lower connection unit, to organize the connection unit onto the LED strip in a fixated arrangement.
  • the connections according to the present invention are designed with specific geometry that fits securely over each individual LED.
  • the connection units consist of two main parts.
  • the upper connection unit has a tube that may be glued to the fiber optics, and a rectangular cap that matches the exact size of the LED component on the strip.
  • the lower unit suitably is a clamp that snaps around the LED strip and clicks into the upper unit, thereby fastening the fiber optics perpendicularly to the LED component.
  • fig.1 one example is shown in fig.1.
  • the connections allow light from the LED strips to be efficiently transferred to the fiber optic threads.
  • the modular design makes it easy to attach, detach, and replace the LED strips.
  • the present invention can be used in a wide range of applications, from interior design to safety signage. Additionally, it offers exciting possibilities in fashion, creating dynamic clothing and accessories, and in the automotive industry for innovative vehicle interior lighting. Its versatility also extends to event design and advertising, where it can be used for eye- catching, changeable displays, decorations and artworks. Moreover, the proposed system according to the present invention offers a range of advantages over previous technology, including ease of assembly, cost-effectiveness, and increased flexibility in design and maintenance. According to one embodiment of the present invention, the fixated fiber optic threads are arranged overlapping to one another.

  • the present invention also refers to a method for producing an optical fiber textile according to the present invention.
  • said method comprises: - sorting fiber optic threads where edges of each section is mixed with the next, for providing sorted bundles; - gluing the sorted bundles of the fiber optic threads into a lead-in tube, preferably by using epoxy glue; and - the lead-in tube and incorporated fiber optic threads are cut proving a clean cut, preferably by using a heated scalpel (hot knife) or cutting tool; and - gluing the lead-in tube into the tube unit.
  • a heated scalpel hot knife
  • the textile is machine woven with fiber optic thread in the weft.
  • the selvedge is undone to reveal the ends of the fiber optics.
  • the fiber optics are then sorted, with the edges of each section mixed with the next.
  • This sorting is to make the edges of the pixels in the fabric less distinct, to allow for smooth gradients between pixels, i.e. to provide fading between nearby pixels to erase sharp edges. From fig.3 one may see sorted fiber optics, and notice how the boundary between two pixels are blended, creating a fading. Then sorted bundles of fiber optics are glued with epoxy into a plastic tube, and the plastic tube and fibers are cut with a heated scalpel, creating a clean cut that does not reduce brightness of the light (see fig.4 and 5). The tube is then glued into the top buckle, i.e. the lead-in tube is glued into the tube unit.

  • the upper connection part 5 has one connection end 51 arranged to be fixated to the lower connection unit 4, said upper connection unit 5 comprising an open end 52 with a tube unit 53 arranged for including fixated fiber optic threads 6 arranged to be connected to the LED strip 2.
  • the LED strip 2 comprises surface mounted LEDs 21 (e.g. SMD5050) intended to match the connection ends 51 of the upper connection parts 5.
  • said connection portions 21 have an extended geometry possible to fixate into a matching open geometry of the connection ends 51.
  • the lower connection unit 4 is a clip which may be arranged around the LED strip and to fixate the upper connection part 5 being clicked into lower connection unit 4.
  • the lower connection unit 4 may be provided with one or more grooves 48, suitably two such grooves 48 on opposites sides, that match one or more wings 58 on the upper connection part 5 (see in fig.1). This is suitable to lock the lower connection unit 4 and the upper connection part 5 to one another in a secure way.
