Definitions

  • the present invention relates to an escape route marking for an aircraft.
  • escape route marking which is also referred to as emergency marking
  • Photoluminescence is sometimes referred to as afterglow and / or phosphorizing.
  • the safety requirements for the escape route marking are specified, for example, in the German industrial standard DIN 67 510.
  • the strips are laid in a straight line in the floor and show the passengers and the crew in an emergency the way to the exits and emergency exits.
  • photoluminescent strips have become increasingly prevalent in the design of aircraft, since they can be operated without a power supply and, in the case of the pigments available today, luminesce sufficiently long and brightly in the dark.
  • WO 96/33093 A1 For example, emergency lighting is known in which a photoluminescent strip is incorporated in a transparent plastic.
  • dyes for the photoluminescent material xylene, 2-butoxyethanol and cyolohexanone are used.
  • a photoluminescent reflector layer is known in which phosphorescent pigments are applied by screen printing in patterns on a substrate.
  • directional displays are known for the escape route, in which photoluminescent agents are applied to a carrier material by spraying or screen printing.
  • EP 0 489 561 A1 is a permanently fluorescent layer known in which color pigments are incorporated into a polymer matrix.
  • the fluorescent material may be incorporated in a carrier which imparts different optical properties to the fluorescent light through additional filters.
  • Out FR 2 308 155 A1 are security signs deposited with photoluminescent material, in which a dispersion with photoluminescent pigments is applied to a transparent layer of plastic material.
  • the present invention has for its object to provide an escape route marking, which can be used with simple means permanently in the passenger compartment of an aircraft.
  • the escape route marking according to the invention is suitable for the passenger compartment of an aircraft.
  • the escape route marking has a multiplicity of elongated segments, which are arranged one behind the other along the escape route to be marked on the underground.
  • the elongated elements may have any shape, in particular a straight or a curved course.
  • Each segment has a carrier module and a light module.
  • the light module is arranged on the carrier module.
  • the light module consists of a substantially transparent plastic material, in which photoluminescent pigments are incorporated, which produce the desired afterglow in the dark.
  • the pigments are microscopically encapsulated in a second material such that liquid and moisture can not get in contact with the pigments.
  • the pigments are completely encapsulated in the second material.
  • the material for the encapsulation is different from the plastic material into which the encapsulated pigments are incorporated.
  • the invention is based on the finding that the lack of luminosity or the darkening of the light modules, which can manifest themselves, for example, in brown or black spots, are due to liquid and / or moisture vapor which, over time, trigger a chemical reaction of the pigments, as a result, a brown color, so-called pigment corrosion, occurs. Microscopic encapsulation of the pigments ensures that the pigments do not corrode over time and therefore do not luminesce to lose. Also, a particular advantage of the escape route marking according to the invention is that the light module can be cut without the cut surface can corrode.
  • the second material is preferably a plastic material.
  • a silicate or a glass can also be used.
  • the transparent plastic material of the light module has a thickness of 0.1 to 2.0 mm, preferably the transparent plastic material is produced with a thickness of 0.2 to 1.5 mm.
  • the transparent plastic material forms a matrix in which the microencapsulated pigments are maintained in a preferably uniform distribution.
  • the transparent plastic material is extruded together with the pigments.
  • photoluminescent pigments are used which contain strontium aluminate. These pigments can be processed in solvent-based paints, printing inks, thermal and printing paste and plastisols.
  • Polypropylene and polyethylene are particularly suitable for the encapsulation of the pigments.
  • the material may be further grafted on, in particular to achieve the desired microencapsulation.
  • a maleic anhydride grafted polypropylene can be used for encapsulation.
  • plastic materials that provide sufficient microencapsulation of the pigments possible.
  • the encapsulated pigments are incorporated in the finished light module in the polymer matrix of the first plastic material.
  • FIG. 1 shows a carrier module 10 which has a cuboid shape and is formed as an elongated strip.
  • the carrier module is made of a plastic and may be glued or screwed to the floor of the passenger compartment, for example. It is not absolutely necessary that the carrier module has a straight course, also the carrier module or the entire escape route marking may have a curved course.
  • a lighting module 12 Arranged on the carrier module 10 is a lighting module 12.
  • the lighting module 12 can be glued onto the carrier module 10, for example. It is also possible to connect the light module 12 otherwise with the carrier module 10.
  • the light module 12 can be extruded onto the carrier module or applied by screen printing.
  • the thickness d of the light module is about 0.2 mm to 1.5 mm.
  • the light module 2 consists of a transparent plastic material (binder) are incorporated in the microencapsulated photoluminescent pigments.
  • photoluminescent particles Strunziumaluminate be used.
  • the pigments may also contain dysprosium oxide and europium oxide.
  • the pigments are completely microencapsulated in a plastic material.
  • This may be a polyethylene that has been grafted with anhydrides to achieve complete microencapsulation of the pigments.
  • FIG. 2 shows an alternative construction of an escape route marker in cross section, in which a light-emitting module 16 is arranged in a carrier module 14.
  • the carrier module 14 has in its cross-section lateral boundary walls 18, which form a trough-shaped receiving space for the light-emitting module 16.
  • projections 20 are provided which extend in the longitudinal direction of the carrier module and which serve for better bonding to the substrate.
  • Covered is the carrier module with a U-shaped cover rail 22, which consists of a transparent material and forms a step protection for the light-emitting module 16.
  • the carrier rail 22 has side walls 24 with a nose 26 projecting at its end, each of which engages behind a projection on the side walls 18.
  • FIG. 3 shows a detailed view of microencapsulated pigments 28 which are completely encapsulated with a second material 30.
  • the second material 30 is transparent to allow the light of the pigments to escape.
  • a sheath 30 Within a sheath 30, a plurality of pigments are combined into a cluster. The individual microencapsulated pigments are held in a matrix of the plastic material.
