Definitions

  • the present invention relates to an electroluminescence fiber hose that comprises a built-in electroluminescence fiber (referred to as "ELF" hereinafter).
  • ELF built-in electroluminescence fiber
  • Fig. 5 is an explanatory view representing ELF alone (Japanese Patent Application No. 6-236797).
  • This ELF 2 comprises a linear core electrode 21, a luminescence layer 22 disposed around the core electrode 21, a transparent electrode layer 23 disposed around the luminescence layer 22, additional electrodes 24 spirally disposed around the transparent electrode layer 23, an inner and outer coverings 25 and 26 covering the aforementioned members and the like.
  • the core electrode 21 and the additional electrodes 24 are connected to an actuation circuit 27 for an inverter or the like, and further connected to an AC power source 28 of 100 V (50/60 Hz), or a DC power source 29 of 3-12 V.
  • This ELF 2 emits light from the tubular luminescence layer 22 provided between the core electrode 21 and the transparent electrode 23 when an alternating voltage is applied between the electrodes, and it has been used as illuminations and the like.
  • ELF of the aforementioned type has drawbacks to be solved such as those mentioned below, when it is used by itself.
  • ELF 2 is thin and light, it can be easily handled, but it is poor in tensile strength. Therefore, it may be destroyed, fractured, or suffer from breaking by external force.
  • ELF 2 uses PVC (a soft vinyl resin) or the like for the coverings 25 and 26 in order to obtain good light transmission.
  • PVC a soft vinyl resin
  • the coverings 25 and 26 in order to obtain good light transmission.
  • PVC a soft vinyl resin
  • the luminescence layer 22 may be degraded with moisture.
  • ELF 2 Since ELF 2 emits light linearly, its light emission is thin, and quantity of light is small. Therefore, it is difficult to be recognized from a distant place.
  • ELFs may be bundled in order to improve luminance. However, light emission from the backside (shady side of the bundle) is considered wasteful, and in addition, overlapped light emission may not be uniform or regular. When they were arranged in a row, the luminance may vary depending on the viewing angle.
  • ELFs 2 emitting light in blue green, red, orange, yellow, brown, bronze, white and the like.
  • each ELF can exhibit only a single color, and it is impossible to obtain multiple colors with a single ELF.
  • ELF since ELF has a thin linear shape, it affords a monotonous emission line when it is fixed. If mixed color or complex emission line is desired, laborious fixation work would be required.
  • the object of the present invention is to provide an ELF hose which has improved properties as for all of strength, attachability, water resistance, quantity of light and ornamentalness, compared with a case where ELF is used alone, and hence realizes expanded applications of ELF.
  • an electroluminescence fiber hose comprising a transparent or translucent tubular hose member having flexibility and elasticity, and one or more electroluminescence fibers linearly or spirally disposed on inner surface of the hose member or inside the hose member.
  • the second embodiment of the invention corresponds to the electroluminescence fiber hose of the first embodiment, wherein the one or more electroluminescence fibers are spirally disposed side by side with one or more hollow tubes or solid cords having flexibility and elasticity.
  • the third embodiment of the invention corresponds to the electroluminescence fiber hose of the first or second embodiment, wherein the one or more electroluminescence fibers are contained in one or more hollow tubes having elasticity.
  • the fourth embodiment of the invention corresponds to the electroluminescence fiber hose of the first embodiment, wherein the hose member comprises an inner hose member and a cover layer covering the one or more electroluminescence fibers wound around the inner hose member.
  • Fig. 1 represents an ELF hose according to the first embodiment of the present invention.
  • the ELF hose of this embodiment comprises a hose member 1, ELFs 2 and the like.
  • the hose member 1 is a tubular member made of a transparent or translucent resin having flexibility and elasticity, such as polyurethane and polyvinyl chloride. Polyurethane is more excellent in transparency and strength as compared with vinyl chloride, and they can be properly used depending on applications.
  • the outer surface of this hose member 1 may further be coated with a transparent resin.
  • each ELF 2 is supported by the hose member 1, and therefore improved tensile strength can be obtained.
  • the apparent diameter of ELF 2 can be made larger.
  • the hose member 1 has proper weight per unit length, it is advantageous for its attachment, handling and the like. Because the hose member 1 has flexibility and property of restoring its original shape, it can be made more durable against deformation by applying internal pressure. Moreover, because it can be deformed, it can fit a surface to which the hose is attached, and easily adhered to the surface. Therefore, it can be easily used as a substitute for ornaments that have conventionally utilized LED, electric bulbs and the like.
  • Each ELF 2 is covered with the hose member 1, and therefore water resistance and weather resistance of ELF 2 can be improved by using a waterproofed type special connector to maintain the inside airtight.
  • electrodes of ELF 2 and the like are not exposed to the outside, and therefore the hose can also be used in an explosion prevention area having, for example, volatile gas atmosphere or the like.
  • the hose member 1 Since the hose member 1 is hollow, it can contain an inserted resin stick, wire rope, rope made of synthetic fibers such as Kevlar (trade name) and the like as a core member, and it can be placed vertically, passed between members or places, or hung from a member or place.
  • Kevlar trade name
  • the hose member 1 has one or multiple ELFs 2 spirally disposed on its internal surface or in its inside. Each ELF 2 itself is one similar to that of Fig. 5.
  • ELF 2 Since ELF 2 is disposed spirally, the hose does not exhibit directivity, i.e., it exhibits the same illumination effect irrespective of the viewing direction. Furthermore, since ELF 2 present on the side opposite to a viewer can also be seen, continuous wavy illumination or illumination composed of multiple crossing wavy lines can be obtained.
  • ELC 2 is disposed spirally, the hose can afford regular and three-dimensional illumination.
  • the winding scheme of the spiral for example, by winding denser with a smaller lead angle, increased density of light can be obtained.
  • a crossing pattern can be obtained, and two or more colors can be used. In such a case, by alternately turning on and off the multiple ELFs 2, more attractive illumination effect can be obtained.
  • Fig. 2 represents an ELF hose according to the second embodiment of the present invention.
  • two or more hollow tubes or solid cords 3 are sandwiched between ELFs 2, and spirally disposed (embedded) on the inner surface of the hose member 1 in a manner similar to that of ELFs 2.
  • ELFs 2 spirally disposed (embedded) on the inner surface of the hose member 1 in a manner similar to that of ELFs 2.
  • Their detailed structure as well as production method therefor will be explained hereafter.
  • the ELF hose of the second embodiment can be produced by, as shown in Fig. 2(A), winding a strip-like member composed of ELF 2A and four tubes 3A composed of resin cords and the like, which are disposed side by side with the ELF 2A so that two of them should be disposed each side of the ELF 2A, and a similar strip-like member composed of ELF 2B and four tubes 3B, which are disposed side by side with the ELF 2B, as a double-line spiral around a jig, (mandrel) M (winding step), and covering them with the hose member 1 composed of a covering resin (covering step).
  • the hose member 1 In the winding step, by winding the strip-like members so as not to form any gap, the hose member 1 can be prevented from flowing into a space between ELF 2 and the and the mandrel M due to slip of the strip-like members during the covering step, and a uniform hose member 1 can be formed.
  • the tubes 3 are provided in the ELF hose of the second embodiment, light transmitting the hose is refracted and irregularly reflected to afford beautiful illumination. When the tubes 3 are hollow, this effect is further enhanced.
  • the tubes 3 also serve to maintain a pitch of the spiral during the production, and afford good appearance. Furthermore, since they have good elasticity, the hose is not broken in use even if the hose is slammed by feet, and in spite of such strength, it can be made with a relatively small weight. Moreover, the property of restoring the original shape of the hose is enhance by the tubes 3, and thus the hose becomes unlikely to suffer from kinks (angles) even if it is bent with a relatively small radius.
  • Fig. 3 is a cross-sectional view of an ELF hose according to the third embodiment of the present invention.
  • each ELF 2 is inserted into a hollow tube 4 made of transparent or translucent resin, and spirally wound in the same manner as in the second embodiment.
  • water resistance, as well as reflection and refraction effects can be enhanced by accommodating ELF 2 in the hollow tube 4.
  • the hollow tube 4-2 one colored in the same color as the luminescence color of ELF 2 is effective.
  • Fig. 4 consists of sectional views representing the fourth embodiment of the ELF hose of the present invention.
  • each ELF 2 is spirally wound around a transparent or translucent inner hose member 5, and the outer surface thereof is covered with a cover layer 6 made of a transparent or translucent resin.
  • the production of the hose becomes very easy, and even if ELF 2 itself is coated with polyvinyl chloride, water resistance and protection effect for ELF 2 can be improved by using resins excellent in strength and water resistance (e.g., polyurethane) for the inner hose member 5 and the cover layer 6 so that the inner hose member 5 and the cover layer 6 should be fused together.
  • resins excellent in strength and water resistance e.g., polyurethane
  • a gap having a cross section of extruding shape S may be formed between ELF 2 and the cover layer 6.
  • This gap can preferably serves to prevent outer force from directly acting on ELF 2, and afford beautiful illumination because of irregular reflection by an air layer in the gap S.
  • the hose When the hose is used as an overhead warning indication hose at low ceiling, stairway etc., it secures safety even if someone hits his head or the like on it, and ELF itself is unlikely to be broken, because of its cushioning effect.
  • the hose may also be used as a warning rope in black and yellow colors (tiger rope).
  • the hose can be used instead of conventional warning tubes for night use comprising LED or electric bulbs, and eliminate the drawback of the conventional tubes, i.e., breakage of electric bulbs and LED. Therefore, conditions for use concerning installation places, handling and the like may be greatly relaxed, and hence its application may be expanded. That is, it can be used as illumination on street, deck and gangway ladder of ships and the like, where it may be slammed by feet.
  • ELF When ELF is disposed with an extremely large lead angle (90°), ELF will be disposed substantially linearly.
  • the production apparatus can advantageously be made simpler.
  • the ELF hose of the present invention realizes improvements over the use of ELF alone, that is, (1) larger diameter, (2) higher strength, (3) higher water resistance and weather resistance, (4) ease of attachment to a flat surface, (5) bending resistance, (6) ease of increasing quantity of light, (7) improved illumination effect obtained by using two or more colors, and alternately tuning on and off ELF for each color. Therefore, the present invention expand applications of ELF.
