Abstract
Description
この発明は、電界発光ファイバーを蓄光体で被覆した蓄光ネオン管に関する。The present invention relates to a phosphorescent neon tube in which an electroluminescent fiber is coated with a phosphorescent material.
電界発光ファイバーは、電界発光素子をファイバ状に形成したもので、線状の芯電極と、その芯電極の外周に配置された発光層と、発光層の外周に配置された透明電極層と、透明電極層の外周に螺旋状に配置された付加電極と、その外周を覆う被覆とを備えている。芯電極と付加電極は電界発光ファイバの一端において交流電力供給源に接続されており、芯電極と付加電極との間に一定の交流を印加することにより、発光層が発光する。The electroluminescent fiber is an electroluminescent element formed in a fiber shape, a linear core electrode, a light emitting layer disposed on the outer periphery of the core electrode, a transparent electrode layer disposed on the outer periphery of the light emitting layer, The additional electrode spirally arranged on the outer periphery of the transparent electrode layer and a coating covering the outer periphery are provided. The core electrode and the additional electrode are connected to an AC power supply source at one end of the electroluminescent fiber, and the light emitting layer emits light by applying a constant alternating current between the core electrode and the additional electrode.
このような電界発光ファイバーは、各種イルミネーションや警告灯などの用途への適用が期待されている。しかし電界発光ファイバーはその直径が2〜3mm程度と細く、強度、光量等に限界がある。また発光層22に用いられている電界発光材料は湿気等に侵されやすいため屋外の用途への適用には限界があった。Such an electroluminescent fiber is expected to be applied to various illuminations and warning lights. However, the diameter of the electroluminescent fiber is as thin as about 2 to 3 mm, and there is a limit in strength, light quantity, and the like. Moreover, since the electroluminescent material used for the light emitting layer 22 is easily affected by moisture or the like, there is a limit to application to outdoor applications.
また電界発光ファイバーの芯電極および付加電極も非常に細いため抵抗が大きく、流し得る交流電流値には限界があった(例えば25〜50mA)。従って必要な輝度を得ることができる電界発光ファイバーの長さも、この許容最大電流値により制約され、例えば直径2.1mmの電界発光ファイバーの許容最大電流値は、周波数にもよるが130Vで50mA、長さは30mが限界であった。供給電流値を許容最大電流値内に抑えたまま電界発光ファイバー長をこれ以上長くしようとすると電流値が不足し、必要な輝度が得られないことになる。Moreover, since the core electrode and the additional electrode of the electroluminescent fiber are also very thin, the resistance is large, and there is a limit to the AC current value that can be passed (for example, 25 to 50 mA). Accordingly, the length of the electroluminescent fiber capable of obtaining the necessary luminance is also limited by this allowable maximum current value. For example, the allowable maximum current value of the electroluminescent fiber having a diameter of 2.1 mm is 50 mA at 130 V, depending on the frequency. The maximum length was 30m. If the electroluminescent fiber length is made longer than this while the supply current value is kept within the allowable maximum current value, the current value becomes insufficient and the necessary luminance cannot be obtained.
本発明はこのような電界発光ファイバーの実用化における問題を解決し、強度、取付け性、耐水性、光量等の性能が十分であって屋外への適用も可能な電界発光ファイバーを用いた蓄光ネオン管を提供することを目的とする。The present invention solves such problems in the practical application of electroluminescent fibers, and is a phosphorescent neon using an electroluminescent fiber that has sufficient performance such as strength, mountability, water resistance, and light quantity and can be applied outdoors. The purpose is to provide a tube.
このような目的を達成する本発明の第1の態様による蓄光ネオン管は、交流電力供給用の導線を蓄光体で被覆してなる絶縁電線と、前記絶縁電線の内部に配置された少なくとも一条の電界発光ファイバーと、前記絶縁電線および前記電界発光ファイバーを被覆する蓄光体を備えたことを特徴とする。The phosphorescent neon tube according to the first aspect of the present invention that achieves such an object includes an insulated wire obtained by coating a conducting wire for supplying AC power with a phosphorescent material, and at least one strip disposed inside the insulated wire. An electroluminescent fiber, and a phosphorescent body covering the insulated wire and the electroluminescent fiber are provided.
本発明の第1の態様による蓄光ネオン管によれば、電界発光ファイバーをさらに蓄光体で被覆することにより、電界発光ファイバーの絶縁性および耐環境性を向上することができる。また電界発光ファイバーを複数用い螺旋状に配置することにより単位長当りの光量を増加することができる。さらに被覆材として蓄光体を用いることにより、輝度をさらに向上することができる。According to the phosphorescent neon tube according to the first aspect of the present invention, the insulation and environmental resistance of the electroluminescent fiber can be improved by further covering the electroluminescent fiber with the phosphorescent material. Moreover, the light quantity per unit length can be increased by using a plurality of electroluminescent fibers and arranging them in a spiral shape. Further, the luminance can be further improved by using a phosphorescent material as the covering material.
本発明の蓄光ネオン管は内部に電力供給用の電線を内蔵しているので、複数の電界発光ファイバーを連結して電力を供給することができるので、各々の電界発光ファイバーの許容最大電流値内の電流で駆動可能な長寸の蓄光ネオン管を提供することができる。Since the phosphorescent neon tube of the present invention has a built-in electric power supply wire, power can be supplied by connecting a plurality of electroluminescent fibers, and therefore within the allowable maximum current value of each electroluminescent fiber. It is possible to provide a long-sized phosphorescent neon tube that can be driven with an electric current of.
本発明の第2の態様による蓄光ネオン管は、上述した第1の態様による蓄光ネオン管の可撓性と輝度を向上させた蓄光ネオン管であって、高効率な発光性能を実現する。The phosphorescent neon tube according to the second aspect of the present invention is a phosphorescent neon tube having improved flexibility and brightness of the phosphorescent neon tube according to the first aspect described above, and realizes high-efficiency luminous performance.
以下、本発明の実施形態を説明する。Embodiments of the present invention will be described below.
本発明による蓄光ネオン管は、所定の長さを有するキャブタイヤコードと、キャブタイヤコードの外周に配置された電界発光ファイバーと、その外周を覆う蓄光体層を備えており、さらに端部には交流電源に接続するための端子部が備えられていて、図1の模式図のごとくである。A phosphorescent neon tube according to the present invention includes a cabtyre cord having a predetermined length, an electroluminescent fiber disposed on the outer periphery of the cabtire cord, and a phosphorescent material layer covering the outer periphery, and further on an end portion. The terminal part for connecting with AC power supply is provided, and it is like the schematic diagram of FIG.
キャブタイヤコードは、電界発光ファイバーに交流電力を供給するための複数本の導線と蓄光体絶縁塗膜から成り、複数本の導線は各端子に接続されている。各端子はインバータ等の駆動回路を介して電源に接続されている。電源は商用の交流電源でも直流電源であってもよい。The cabtyre cord is composed of a plurality of conductors for supplying AC power to the electroluminescent fiber and a phosphorescent insulating coating, and the plurality of conductors are connected to each terminal. 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.
電界発光ファイバーは、線状の電極と、その電極の内側に配置された発光層と、外周に螺旋状に配置された付加電極と、その外周を覆う蓄光体層を備えている。蓄光体層は電界発光ファイバーを単独で使用する場合には耐候性を高めるためにも活用され厚めが理想的であるが、本発明の蓄光ネオン管においては所定の層厚保で良い。The electroluminescent fiber includes a linear electrode, a light emitting layer disposed inside the electrode, an additional electrode spirally disposed on the outer periphery, and a phosphor layer covering the outer periphery. When the electroluminescent fiber is used alone, the phosphorescent material layer is also used to increase the weather resistance and is ideally thick. However, in the phosphorescent neon tube of the present invention, a predetermined layer thickness may be maintained.
蓄光体層は、電界発光ファイバーを外部環境から保護し且つ電界発光ファイバーの光を遮断せず輝度を向上させる効果を具備する。このような材料としてはアルカリ土類アルミン酸塩に賦活剤として希土類元素を含有する蓄光体が好適である。またこれらに紫外線吸収剤を含有せしめることが好ましい。これにより発光層を保護し蓄光ネオン管の耐候性を高めることができる。The phosphor layer has the effect of protecting the electroluminescent fiber from the external environment and improving the luminance without blocking the light of the electroluminescent fiber. As such a material, a phosphorescent material containing a rare earth element as an activator in an alkaline earth aluminate is suitable. Moreover, it is preferable to contain an ultraviolet absorber in these. Thereby, a light emitting layer can be protected and the weather resistance of a luminous neon tube can be improved.
一般に電界発光ファイバーが発光する光の周波数(色調)は印加される電圧およびその周波数に依存し、電圧および周波数が一定であれば光の色調も一定であるが、蓄光体層により所望の色の光を演出することができ、蓄光ネオン管の装飾性を高めることができる。In general, the frequency (color tone) of light emitted from the electroluminescent fiber depends on the applied voltage and the frequency. If the voltage and frequency are constant, the color tone of the light is also constant. Light can be produced and the decorativeness of the phosphorescent neon tube can be enhanced.
以上のように構成される本発明の蓄光ネオン管は、可撓性があり且つ耐候性があるので所望の基材に取付けたりそれ自体を所望の形状に折り曲げて屋内外のイルミネーション等に用いることができる。また蓄光体層を有する電界発光ファイバーを螺旋状或いは複数配置することにより十分な輝度を確保することができる。さらに本発明の蓄光ネオン管は複数を連結して所望の長さにすることができるので、道路工事現場や室内、通路、駐車場などの広い範囲に設置して誘導用表示や警告灯として機能させることも可能である。The phosphorescent neon tube of the present invention configured as described above is flexible and weather resistant, so it can be attached to a desired base material or bent into a desired shape and used for indoor and outdoor illumination. Can do. In addition, sufficient luminance can be ensured by arranging spirally or a plurality of electroluminescent fibers having a phosphor layer. Furthermore, since the phosphorescent neon tube of the present invention can be connected to a desired length, it can be installed in a wide range of road construction sites, indoors, passages, parking lots, etc. and functions as a guidance display or warning light It is also possible to make it.
以上の実施例からも明らかなように、本発明の蓄光ネオン管は電界発光ファイバーへの電力供給用電線を管内に内蔵しているので、電線を接続することにより所望の長さに連結することができ、個々の蓄光ネオン管の電界発光ファイバーに許容最大電流値以下の安全電流を供給し、且つ十分な輝度を確保することができる。As is clear from the above embodiments, the phosphorescent neon tube of the present invention incorporates a power supply wire to the electroluminescent fiber in the tube, so that it can be connected to a desired length by connecting the wire. Therefore, it is possible to supply a safe current below the allowable maximum current value to the electroluminescent fibers of the individual phosphorescent neon tubes and to ensure sufficient luminance.
