Definitions

  • the invention relates to a lighting device for use on textile devices and textile devices equipped therewith.
  • Textile devices in the sense of the invention are in particular:
  • bale openers such as bale openers, cleaners, mixers, cards, draw frames, tape winders and combers;
  • - spinning machines such as flyers, air spinning machines, ring spinning machines and rotor spinning machines;
  • auxiliary devices such as gates (driven / not driven), transport pipes, fans, suction systems, collecting containers, for example for waste;
  • Nonwoven machines such as fleece winders, needling machines, brims, stacker and
  • DE 10 2015 118 762 A1 discloses a lighting device with a plurality of lighting elements. The lighting elements are controlled so that they at least one Show an operating parameter and / or an operating process of the spinning preparation machine itself and / or another spinning preparation machine that is in a processing chain with this machine.
  • the lighting elements are attached to a respective outer wall of the spinning preparation machine, which preferably runs perpendicular to the floor on which the respective spinning preparation machine is installed.
  • This has the disadvantage that the lighting elements cannot be seen from the rear of the wall. Accordingly, at least two lighting devices must be provided, it should be ensured that the spinning preparation machine can be monitored from all sides.
  • the lighting elements have to be protected particularly against mechanical influences, or the lighting device has to be attached to places that are hardly or not at all exposed to such influences. This enormously reduces the flexibility of use.
  • Signal lights are also known, the light-emitting light elements of which emit their light in the direction of a tip of a cone facing them.
  • the circumferential side surface of the cone reflects this light to the sides.
  • this has the disadvantage of a complex construction; the reflector must somehow be fixed in its position with respect to the lighting element. This is generally done by encasing the entire device, which entails costs.
  • the light is only visible at an angle of 90 ° to the light exit side of the lighting element. Looking vertically at the light exit side, the light may not be visible or may be difficult to detect.
  • the object of the invention is to counter the aforementioned disadvantages.
  • a lighting device which is designed to be attached to a textile device or to be integrated into the textile device.
  • the lighting device has at least one lighting section with at least one lighting part and a transparent profile element.
  • the lighting part comprises an arrangement with at least one lighting element.
  • transparent means that light rays can pass through the profile element. That is, the profile element does not have to be crystal clear or colorless.
  • the profile element is designed and arranged with a light incidence side on a light-emitting side of the lighting section, deflecting light emitted by the lighting section in the direction of at least one outer surface of the profile element facing away from the lighting section.
  • the deflection occurs in such a way that the deflected light is visible from different angles on the at least one outer surface from the outside in relation to the lighting device.
  • This has the advantage that the emitted light is only visible from the outside due to the design of the profile element.
  • An additional fixation of the profile element is not necessary, since this is via the Luminous section takes place, which is provided according to the invention only for emitting light and electrical wiring.
  • the profile section also enables mechanical protection of the lighting part simply by placing the profile element on the lighting part or by fitting the lighting part by means of the profile element. The result is a very simple and inexpensive setup.
  • this structure permits the design, in particular, of geometric arrangements with a plurality of lighting elements.
  • the lighting element arrangement can be attached to an element of the textile device at low cost and can be securely wired.
  • the profile element preferably has a first surface. Starting from an outer edge of the arrangement, the first surface forms an acute angle with the light incidence side of the profile element and is inclined toward a center of the light incidence side.
  • the transparency of the profile element and this inclination of the first surface have the result that the light emitted by the lighting part strikes the first surface at an acute angle and is deflected on this transparent surface due to optical deflections, as explained above. This further simplifies the construction of the lighting device.
  • the lighting element or elements appear to be “standing in the air” optically in the center of the profile element. This creates the impression that the lighting element arrangement is not behind the light incidence side but in the middle of the profile element.
  • the profile element preferably also has a second surface.
  • the second surface is arranged like the first surface. It is also opposite the first area. This has the surprising effect that the light emitted by the lighting element arrangement is visible from the outside around the entire lighting device, even in the viewing direction essentially perpendicular to the light incidence side of the profile element in the direction of the lighting element arrangement.
  • an inner and / or outer contour of the profile element facing the lighting element arrangement is pyramid-like or truncated pyramid-like.
  • This is a particularly simple design option which, in conjunction with the transparency of the lighting device, enables a very elegant appearance.
  • this shape enables the use of only a single lighting element, and it is nevertheless visible from all viewing sides. Here, too, there is a "floating" light when lit.
  • the base surface of the pyramid or the truncated pyramid preferably has the shape of a circle, an ellipse or a polygon with straight and / or curved sides. This promotes the deflection of the emitted light to all outer sides of the profile element and is also very attractive.
  • Each of the aforementioned lighting devices can have a further lighting section which, like the aforementioned, is configured as a lighting section.
  • the one lighting section is designed and arranged on the further lighting section in such a way that the arrangements of the lighting elements of both lighting sections essentially emit their light in one direction and the light of the further lighting section is prevented from entering the profile element of the to penetrate a luminous section. This makes it possible to also form the “multi-storey” signal lights mentioned at the beginning.
  • the lighting sections are preferably arranged one behind the other, viewed in the direction of a main emission direction of the lighting element arrangements of the lighting sections.
  • the further lighting section has cabling designed to make electrical contact with one of the lighting sections attached. This makes the manufacture of the signal light particularly easy.
  • the profile element of the further lighting section and the one lighting section are preferably attached to one another.
  • the result is a multi-part lighting device that is easy to assemble.
  • the arrangement can comprise a plurality of lighting elements arranged in a row.
  • the Profile element of the same lighting part extends along the row of lighting elements.
  • the profile element seen along its longitudinal extent, preferably has a triangular or trapezoidal cross section. One side of this triangle or trapezoid is adjacent to the light-emitting side of the lighting section. That is, it is sufficient for the profile element to have a very simple geometric shape and to be produced in order to achieve the light deflection according to the invention.
  • a textile device is also provided.
  • the textile device has one of the aforementioned lighting devices.
  • the lighting element arrangement of a lighting section is arranged to emit its light outwards in relation to the textile device.
  • the associated profile element is attached to the textile device.

  • the profile element is attached to a holding element which holds the at least one lighting element arrangement.
  • the holding part can be a circuit board, for example. This enables the use of already existing elements of the lighting device.
  • the lighting device can be provided as a module that only has to be attached to the textile device, either by means of the holding part or by means of the profile element.
  • a light output side of the last-mentioned lighting element arrangement is directed in the direction of a floor on which the textile device is set up.
  • This variant is suitable, for example, in the case of a can depositing device, the lighting device protruding into the area of the can moving area, which is dangerous anyway, and thus signaling the danger zone to people passing by, for example by means of yellow flashing lights.
  • the light output side is directed away from the floor.
  • This variant is suitable, for example, in the case of a gate, on the upper side of which the respective lighting device is tamper-proof and without the risk of injury to a person passing by.
  • the light output side is directed parallel to the floor. This is useful if the walls of textile devices are primarily perpendicular to the floor. The protrusion of the profile element enables the all-round detection also parallel to the light output side.
  • Both textile devices can have a controller or can be coupled to such a controller.
  • the controller is set up to control the lighting device in such a way that its lighting element arrangement depicts the presence of a predetermined state, an operating parameter and / or an operating process of the textile device itself and / or another textile device that is in a processing chain with the textile device.
