- the electroluminescent fiber has a limit of the strength and light intensity that can be reduced to about 2 to 3 mm in diameter.
- the electroluminescent material used for the light-emitting layer is susceptible to moisture and the like, so that it may be difficult to seal the outer periphery, which limits its application to outdoor applications.
- the core electrode and the additional electrode of such an electroluminescent fiber are generally very thin, there is a limit to the AC current value that can flow with a large resistance (for example, 25 to 50 mA). Therefore, the length of the electroluminescent fiber that can achieve the required brightness is limited by the allowable minimum current value corresponding to this required brightness, for example, the maximum allowable length of the electroluminescent fiber with a diameter of 2.1 mm is When the voltage value is 130V and the allowable minimum current value is 50mA 30m was the limit.
- the length of the electroluminescent fiber is made longer than this while the supply voltage value is kept within the allowable maximum value (130V), the current value will be insufficient and the required brightness will not be obtained.
- electroluminescent fiber does not emit light immediately when the power supply is interrupted, and has been useful for guidance in an emergency.
- the present invention solves the problems in practical use of such an electroluminescent fiber, and has sufficient performance such as strength, mountability, water resistance, light quantity, etc., and a plurality of them are connected to be elongated.
- the purpose is to provide a phosphorescent neon tube that uses electroluminescent fiber that can be used outdoors and can be used to ensure constant light emission in the event of a power failure.
- a phosphorescent neon tube includes an insulated wire obtained by covering a plurality of conductors for supplying AC power with a first phosphorescent material in layers, and An electroluminescent fiber disposed on the outer periphery of the insulated wire; and a second phosphorescent material layer covering the electroluminescent fiber, wherein the first and second phosphorescent substances are alkaline earth aluminate and
- the insulation and environmental resistance of the electroluminescent fiber can be improved by coating the electroluminescent fiber with the first and second phosphorescent bodies. I'll do it.
- a phosphorescent material as a covering material, it is possible not only to improve the brightness, but also to ensure a minimum illuminance during a power outage emergency.
- a phosphorescent neon tube according to claim 2 of the present invention is characterized in that the first and second phosphorescent layers have a thickness of 5 mm or less.
- the electroluminescent fiber is protected from the external environment, and the light emission and the phosphorescent emission of the electroluminescent fiber are not substantially blocked, so that the light emitting performance is highly efficient. Is realized.
- the phosphorescent neon tube according to claim 3 of the present invention includes a plurality of phosphorescent neon tubes according to claim 1 or 2. It consists of a pipe
- a power supply electric wire is built in, and it is possible to supply electric power substantially free of voltage drop to the plurality of electroluminescent fibers. Therefore, it is possible to provide a long luminous neon tube capable of driving each electroluminescent fiber with a current exceeding the allowable minimum value.
- the flexibility of the phosphorescent neon tube can be improved.
- the phosphorescent neon tube according to the present invention incorporates a power supply electric wire to the electroluminescent fiber in the tube, so that it can be connected to a desired length by connecting the electric wire.
- a safe current exceeding the allowable minimum current value can be supplied to the electroluminescent fiber, and sufficient luminance can be secured, and a minimum illumination can be provided in the event of a power failure.
- FIG. 1 is a schematic view of a phosphorescent neon tube according to a first embodiment of the present invention.
- FIG. 1 is a schematic view showing a phosphorescent neon tube according to the first embodiment of the present invention.
- Example 1
- a phosphorescent neon tube includes a cap tire cord having a predetermined length and a cap pig.
- An electroluminescent fiber disposed on the outer periphery of the cord and a phosphor layer covering the outer periphery are provided, and a terminal portion for connecting to an AC power source is provided at the end.
- a cap tire cord includes a core electrode 1 having a plurality of conductive wires (not shown) for supplying AC power to an electroluminescent fiber, and a first phosphor layer.
- 2 is an insulated wire composed of an insulating coating consisting of two, and a plurality of conductors are connected to each terminal of AC power (not shown) at the end.
- Each terminal is connected to a power source via a drive circuit such as an inverter.
- the power source may be a commercial AC power source or a DC power source.
- the electroluminescent fiber 1 includes concentric cylindrical first and second electrodes (at least the outer second electrode is a transparent electrode), and a light emitting layer disposed between the electrodes. And an additional electrode 4 that is spirally arranged on the outer periphery and electrically connected to the second electrode.
- the second electrode is preferably thin so as to be substantially transparent to light emitted from the light emitting layer, but as a result, generally has a high electric resistance.
- the spiral additional electrode 4 for example, a copper foil or the like is used so that the electric resistance is sufficiently low even if the width is narrow so that the light emission is not substantially concealed, and the voltage applied to the light emitting layer is reduced. Can be prevented.
- the first and second electrodes together with the additional electrode connected to the second electrode, are connected to the corresponding ones of the plurality of conductive wires at the end (not shown).
- the phosphor layer 5 covering the outer periphery of the electroluminescent fiber is composed of a second phosphor layer
- the first and second phosphor layers are preferably used to increase the weather resistance when the electroluminescent fiber is used alone, so it is preferable to use a thicker layer. To be thin, prefer.
- the predetermined layer thickness is preferably 5 mm or less in the phosphorescent neon tube of the present invention.
- the first and second phosphor storage layers have the effect of protecting the electroluminescent fiber from the external environment and not blocking the light of the electroluminescent fiber, and improving the luminance by the stored light emission.
- Alkaline earth aluminate as the material for such phosphor layer and rare earth as activator A phosphor containing a similar element is preferred.
- an ultraviolet absorber in these. This protects the light emitting layer and enhances the weather resistance of the phosphorescent neon tube.
- the frequency (color tone) of light emitted from the electroluminescent fiber depends on the applied voltage and its frequency. If the voltage and frequency are constant, the color tone of light is also constant. The desired color of light can be produced, and the decorativeness of the phosphorescent neon tube can be improved.
