Definitions

  • This invention relates to an apparatus with a lighting element and at least one optical fiber, wherein the lighting element emits an artificial light, wherein the artificial light is guided by the optical fiber, comprising a first and a second end, wherein the optical fiber is embedded in a carrier element, comprising a number of surfaces, wherein the first end of the optical fiber ends in an area of one of the surfaces.
  • the illumination system comprises at least one paving block, in which at least one light source and at least one optical fiber are embedded.
  • a plurality of optical fibers is preferably included within the block, where the optical fibers collect the light from the light source and expose the light at the top surface of the block.
  • the described integration of the light source in the paving block has the disadvantage, that the electrical installation is in an area, where high mechanical stress and humidity is present during use. Additionally, the electrical contact of the illumination system, being embedded in the paving block, has to have a contact line towards an electrical installation. This electrical contact line is another drawback of the described illuminating system.
  • the invention has for its object to eliminate the above mentioned disadvantages.
  • the second end of the optical fiber ends in an area of one of the surfaces of the carrier element, and the lighting element is integrated in a holding mean, being positioned adjacent to the carrier element in such a way, that the artificial light enters the second end of the optical fiber, and leaves the first end at a surface of the carrier element.
  • the key point of the invention is the separation of the lighting element and the optical fiber. So mechanical stress and humidity may eventually access the optical fiber. But due to the modular concept, the carrier element can easily be exchanged in a case of a failure. There is no need to dismount or disconnect the lighting element from an electrical power source, but rather the lighting element can remain in its position.
  • the described apparatus is advantageous for the use in sidewalks, walkways, driveways, pathways and indoor or outdoor floor coverings, landscaping and masonry walls and to provide lighting to other surfaces as desired.
  • the apparatus can also easily be embedded in ceilings and claddings of walls, in planes, trains or ships of all kinds. Also a use in sport stadiums is appropriate.
  • the holding mean is a baseboard.
  • Those kinds of baseboards are often used to encircle the floor in rooms or corridors of all kinds.
  • the described apparatus has the ability to illuminate the named floors, whereas the lighting element is integrated in the baseboard. Needed electrical installations are often shielded behind known baseboards, so that a connection of the described apparatus with the electrical power system is easy and convenient to implement.
  • the artificial light, emitted by the lighting element has to be launched into the optical fiber, the position of the holding mean and the carrier element are mutually depending. Therefore the integration of the lighting element goes hand in hand with the embedding of the optical fiber into the carrier element.
  • the optical fiber is the guiding of the artificial light, being emitted by the lighting element to one of the surfaces of the carrier element.
  • the optical fiber is a cylindrical dielectric waveguide that transmits light along its axis, by the process of total internal reflection.
  • the optical fiber consists of a core surrounded by a cladding layer. To confine the optical signal in the core, the refractive index of the core must be greater than that of the cladding.
  • the boundary between the core and cladding may either be abrupt, in step-index fiber, or gradual, in graded-index fiber.
  • the operating principle of the used optical fiber applies to a number of variants, including multi-mode optical fibers or single-mode optical fibers.
  • the optical fiber may be made of a glass or a polymer.
  • Glass optical fibers may be made from silica, whereas for special purpose, like longer-wavelength infrared applications, other materials, such as fluorozirconate, fluoroaluminate, and chalcogenide glasses may be used. All these glasses have a refractive index of about 1.5, whereas typically the difference between core and cladding is less than one percent.
  • An optical fiber made out of a plastic is commonly a step-index multimode fiber, with a core diameter of 1 mm or larger.
  • Plastic optical fibers often suffer a much higher attenuation than glass fibers, which limits the range of an apparatus using such kind of optical fibers.
  • the inner core of the optical fiber is made out of a Polymethyl methacrylate (acrylic) and that cladding material is a fluorinated polymer.
  • optical fibers are based on a perfluorinated polymer (mainly polyperfluorobutenylvinylether).
  • the lighting element may be a LED, an OLED, a Dielectric barrier discharge (DBD) lamp, a gas discharge lamp, a high intensity discharge lamp, an incandescent lamp, a fluorescent lamp or a high pressure sodium lamp.
  • LEDs Light Emitting Diode
  • OLED organic light emitting diode
  • the emissive layer comprises a thin film of certain organic components.
  • the advantage of the OLED is that it is a homogeneous large area light source with potentially low cost and high efficiency. These OLEDs utilize current flowing through a thin- film of organic material to generate light.
  • the color of light being emitted and the efficiency of the energy conversion from current to light are determined by the composition of the organic thin- film material.
  • LEDs as well as OLEDs have the advantage that they do not produce a large amount of heat, so that even in a case where a tiny carrier is used, cooling has not to be considered.
  • the Dielectric barrier discharge (DBD) lamps are used to efficiently generate radiation in the ultraviolet and vacuum-ultraviolet spectral regions (88nm-350nm) by forming rare-gas and rare-gas halide excimers in a transient plasma.
  • the lighting element not only emits artificial light into the optical fiber, but also into the room surrounding the holding mean.
  • the carrier elements are illuminated but also for example bordering walls.
  • the artificial light, being emitted above the holding mean may function as a kind of guide line for someone walking along the carrier element. Especially in a case of an emergency this kind of embodiment of the apparatus is preferable.

  • the contact mean is a kind of a light guide, needed to launch the artificial light into the optical fiber.
  • One end of this contact mean therefore faces the lighting element, whereas the opposed end of the contact mean forms the contact area.

  • the contact mean has a conic shaped tip, preferably that the conic shaped tip penetrates into the second end of the optical fiber.
  • the conic shaped tip functions as a clip connection, establishing a form- fit conjoint. Furthermore, the conic shaped tip of the contact mean eases the assembly of the described apparatus. If once the connection between the holding mean and the carrier element is established, mechanical stress is not able to disconnect it again.
  • the optical fiber and/or the contact mean and/or the holding mean comprise a color filter.
  • the color filter serves to generate light in just one color, so that red or blue or green light can escape from the first end of the optical fiber.
  • the optical fiber and/or the lighting element can be doped with chemical elements, as phosphor, to achieve colored light.
  • the doped elements absorb and re-emit the artificial light in narrow wavebands, so that colored light is generated.
  • This colored light is especially useful, if the first ends of a number of fibers are arranged in such a way that an illuminated symbol is build on the top surface of the carrier element. These illuminated symbols can be used as a sign for emergency rooms, as advertisements or as decoration of floors, walls or ceilings.
  • a mounting mean is embedded into the carrier element, wherein the mounting mean contains the first end of the optical fiber.

Therefore, the connection mean should possess a reflection index more or less equal to that of the optical fiber. Additionally, optical grease can be used to minimize the reflection of the light at the crossing from the optical fiber into the connection mean. Because of its conic shape the connection mean easily establishes a connection to the optical fiber, guaranteeing a secure bond, which even mechanical stress of the carrier element will not disintegrated.
