Definitions

  • the present invention relates to the field of photoluminescent materials, and its applications.
  • WO8912376 describes a lamp assembly flexible light emitting comprises a plurality of layers thin each comprising a flexible plastic substrate and at least one electrically conductive layer. We work between two other thin layers a first thin layer emitting light, which includes an electroluminescent layer and a light transmitting conductor (24). The second and third thin layers respectively provide a bar bus and rear electrodes.
  • Such devices require the use of a electrically conductive substrate. It is difficult to find support films with both good optical performance (transparency, absence of coloring), and good electrical conductivity.
  • WO0072637 relates to a color display electroluminescent comprising a substrate on which are successively formed a fluorescent conversion layer and / or a fluorescent material containing a color filter, an organic layer, a barrier layer and a structure organic electroluminescent.
  • the organic layer is made of a thermosetting resin and taking under the effect of ultraviolet, the barrier layer containing silicon.
  • Japanese patent application JP10119599 reports to an electroluminescent element presenting a product layered ceramic comprising a substrate, a first electrode effect layer and a first insulating layer, and comprising in at least one of the insulating layers a material dielectric of a specified composition consisting mainly, in molar percentage, from 0.1 to 3% of MgO, from 0.05 to 1.0% of MnO, up to 1% of Y2 03, from 2 to 12% of BaO + CaO and from 2 to 12% SiO2, for a molar percentage 100% BaTiO3.
  • the object of the present invention is to remedy to the drawbacks of the devices of the prior art, in offering a flexible element, very low consumption electric, and producing a homogeneous and constant lighting. Another goal is to achieve long lifespans and thin, of the order of 0.5 mm.
  • the invention relates first of all to a method for the manufacture of an electroluminescent film characterized in that that a cord is deposited on a flexible transparent substrate in a resistive material surrounding at least one zone, and in this that we deposit at least 7 thicknesses of a electroluminescent material by alternative steps coating and drying, and in that we cover the complex thus prepared by a flexible film.
  • the substrate and the backing film are made of insulating plastic.
  • the number of layers of material electroluminescent is between 9 and 14.
  • a flexible opaque or semi-opaque material between areas emitting.
  • the two flexible films are heat sealed around their edges.
  • the invention also relates to a system comprising a element according to the invention and in addition a source supplying an alternating current of the order of 450 Hz.
  • the element consists of a flexible substrate (1) or flexible, for example a polyprolylene film. So substrate (1), a conductive bead (2, 3) is delimited an area (4, 5) on which 9 layers of a electroluminescent material.
  • the whole is subject to a rolling operation when the two exterior films are assembled. All has a thickness of the order of 0.2 to 0.6 mm.
  • the conducting cords are connected, at each of their ends, to a source of alternating current at 450 Hz (or more generally between 50 and 2000 Hz), at low voltage, for example 3 volts.
  • the electrical power required is of the order of 10 mW per cm 2 .
