Description

この発明は、効率低下を抑制するために発光管内部に水銀合金(アマルガム)を封入した蛍光ランプに係わり、光束立ち上がり特性を改善した蛍光ランプに関するものである。   The present invention relates to a fluorescent lamp in which a mercury alloy (amalgam) is sealed in an arc tube in order to suppress a decrease in efficiency, and relates to a fluorescent lamp having improved luminous flux rise characteristics.

1980年に電球類似形状の電球形蛍光ランプが製品化されて以降、この電球形蛍光ランプの電球や一般蛍光ランプと比べて劣る光束立ち上がり特性の改善に関する研究が多々報告され、最近、光束立ち上がり特性を改善したランプの発売・発表が国内各社から相次いでいる。   Since the light bulb-type fluorescent lamp similar in shape to a light bulb was commercialized in 1980, many researches on the improvement of the luminous flux rise characteristic, which is inferior to that of the bulb and the general fluorescent lamp, have been reported. There are a number of lamps released and announced by Japanese companies.

1998年以降、電球形蛍光ランプの小形化が急速に進み、光束立ち上がりの問題を顕在化させた。発光管が細径化し、点灯直後に補助アマルガムから放出される水銀の実効的な管軸方向拡散速度が遅くなったことが、その要因として挙げられる。   Since 1998, the miniaturization of light bulb-type fluorescent lamps has progressed rapidly, and the problem of rising of luminous flux has become apparent. One of the reasons for this is that the diameter of the arc tube is reduced and the effective diffusion rate of mercury released from the auxiliary amalgam immediately after lighting is reduced in the axial direction of the tube.

発光管を樹脂ケースやグローブに収容したグローブ付きランプは、点灯中の発光管温度が一般の蛍光ランプより著しく上昇する。蛍光ランプの発生効率は、内部に封入された水銀の蒸気圧に依存するので、高温下では効率が低下し暗くなる。   In a lamp with a globe in which the arc tube is housed in a resin case or a globe, the temperature of the arc tube during lighting is significantly higher than a general fluorescent lamp. Since the generation efficiency of the fluorescent lamp depends on the vapor pressure of mercury sealed inside, the efficiency decreases and becomes dark at high temperatures.

安定点灯時の水銀蒸気圧を制御するために封入される主アマルガムは、純水銀よりも水銀蒸気圧を低く制御する作用を持つ。その蒸気圧特性は基体金属となるビスマス(Bi)、鉛(Pb)、インジュウム(In)等の組合せと、水銀(Hg)の含有比率により決定される。発光管温度に合わせて選択されたアマルガムを使用することで、高温下でも最大の効率を得ることができる。   The main amalgam enclosed to control the mercury vapor pressure at the time of stable lighting has an action of controlling the mercury vapor pressure lower than pure mercury. The vapor pressure characteristics are determined by the combination of bismuth (Bi), lead (Pb), indium (In), etc., which are base metals, and the content ratio of mercury (Hg). By using an amalgam selected according to the arc tube temperature, the maximum efficiency can be obtained even at high temperatures.

しかしながら、アマルガムは常温においても水銀蒸気圧を低く制御するので、ランプの消灯後、発光管の温度が低下すると管内の水銀蒸気圧は著しく低くなる。このため、再点灯の際は水銀が不足し、主アマルガムの温度が上昇して発光管内の水銀蒸気圧が上昇するまでは非常に暗い。   However, since amalgam controls the mercury vapor pressure to be low even at room temperature, the mercury vapor pressure in the tube will be significantly reduced if the temperature of the arc tube decreases after the lamp is extinguished. For this reason, at the time of relighting, mercury is insufficient, and it is very dark until the temperature of the main amalgam rises and the mercury vapor pressure in the arc tube rises.

再点灯時の光束を補うために、始動後速やかに昇温する部位(電極近傍など)に補助アマルガムが設けられる。補助アマルガムは、常温において主アマルガムよりも水銀蒸気圧の低い材料が用いられ、消灯中に水銀を捕捉する。始動時は水銀を管内に供給し、安定点灯時は主アマルガムより大幅に高温となるので、実質的に管内の水銀蒸気圧を制御しない。   In order to compensate for the luminous flux at the time of re-lighting, an auxiliary amalgam is provided at a site (such as near the electrode) where the temperature is quickly raised after starting. The auxiliary amalgam is made of a material having a mercury vapor pressure lower than that of the main amalgam at room temperature, and captures mercury during light extinction. Mercury is supplied into the tube at start-up, and the temperature is much higher than the main amalgam during stable lighting, so the mercury vapor pressure in the tube is not substantially controlled.

補助アマルガムとして通常使用されるのはInアマルガムである。実際のランプにおいては、箔状もしくは網状のステンレス基材にInをメッキしたものが使用される。当初のアマルガム方式ランプは発光管両端の電極部のみに配置されていたが、現在では放電路中央部にも設けられることが多い。   In amalgam is commonly used as an auxiliary amalgam. In an actual lamp, a foil-like or mesh-like stainless steel base material plated with In is used. The original amalgam type lamp was disposed only at the electrode portions at both ends of the arc tube, but at present, it is often provided at the center of the discharge path.

図9は従来のアマルガム封入ランプの光束立ち上がり特性を模式的に示した図である。補助アマルガムを使用しない場合の特性は、主アマルガム設置部分の温度上昇に対応し、安定光束の80%を得るのに10分以上要する。補助アマルガムを用いた場合は、点灯後1分以内に80%の光束を得ることがわかる。   FIG. 9 is a diagram schematically showing the luminous flux rise characteristics of a conventional amalgam-enclosed lamp. The characteristics when the auxiliary amalgam is not used correspond to the temperature rise of the main amalgam installation part, and it takes 10 minutes or more to obtain 80% of the stable luminous flux. When the auxiliary amalgam is used, it can be seen that 80% of the luminous flux is obtained within 1 minute after the lighting.

図9に示したように、補助アマルガムを用いた場合は、点灯後1分以内に80%の光束が得られるが、実用上は十分とは言えない。例えば、トイレ等に使用する場合は、点灯直後から暗部がないことが望ましい。そこで、主アマルガムの水銀含有量を増加することや(但し、In量との相関には触れていない)、主アマルガムと補助アマルガムをそれぞれ2、3ヶ所に設けることで、光束立ち上がり特性が改善されるとの報告がある。   As shown in FIG. 9, when the auxiliary amalgam is used, 80% of the luminous flux can be obtained within 1 minute after lighting, but it is not practically sufficient. For example, when used for a toilet or the like, it is desirable that there is no dark part immediately after lighting. Therefore, increasing the mercury content of the main amalgam (however, the correlation with the amount of In is not touched), and providing the main amalgam and the auxiliary amalgam at two or three locations respectively, the luminous flux rise characteristics are improved. There is a report.

また、図10に示す「ロングアマルガムチューブ方式」により、光束立ち上がり特性を改善したグローブ付ランプ(EFA15/13)が、発表・発売されている。これは、発光管端部に封着された細管を口金付近まで伸ばすことで低温の最冷部を形成し、細管先端に水銀蒸気圧の高い主アマルガムを固着する方法であり、さらに、金(Au)を材料とする補助アマルガムを使用することにより、図11に示すように従来のグローブ付ランプ(EFA12)と比べて光束立ち上がり特性を大幅に改善し、始動直後の明るさは安定時の35%、2秒後で50%を実現している(例えば、非特許文献1参照)。

In addition, a lamp with a globe (EFA15 / 13) having improved luminous flux rise characteristics by the “long amalgam tube method” shown in FIG. 10 has been announced and put on the market. This is a method in which the coldest part at low temperature is formed by extending the narrow tube sealed at the end of the arc tube to the vicinity of the base, and the main amalgam having a high mercury vapor pressure is fixed to the tip of the thin tube. By using an auxiliary amalgam made of Au), as shown in FIG. 11, the luminous flux rise characteristic is greatly improved as compared with the conventional lamp with globe (EFA12). %, And 50% after 2 seconds (see Non-Patent Document 1, for example).

上記のように、電球形蛍光ランプは1980年に発売されて以来、多くの研究・技術開発により光束立ち上がり特性改善が行われてきたが、図10に示した「ロングアマルガムチューブ方式」のものでも、始動直後の明るさは安定時の35%、2秒後で50%であり、更なる改善ができれば望ましいことである。   As described above, since the light bulb shaped fluorescent lamp has been improved in luminous flux rising characteristics by many researches and technological developments since its launch in 1980, the “long amalgam tube method” shown in FIG. The brightness immediately after start-up is 35% at the stable time and 50% after 2 seconds, and it is desirable if further improvement can be made.

実施の形態1.
図1は実施の形態1を示す図で、電球形蛍光ランプの構造図である。図に示すように、外形はA形、G形があり、それぞれに光色と入力電力の異なる機種がある。電球形蛍光ランプは、U字形の発光管を複数接合して発光部を小形化し、この発光管1をインバータ2で高周波点灯する。発光管1とインバータ2がハウジング部により一体化され、これをグローブ4とカバー3により囲い、口金5が取り付けられている。
Embodiment 1 FIG.
FIG. 1 is a diagram showing the first embodiment and is a structural diagram of a bulb-type fluorescent lamp. As shown in the figure, there are A type and G type outer shapes, and there are models with different light colors and input power. The bulb-type fluorescent lamp has a plurality of U-shaped arc tubes joined together to reduce the size of the light emitting portion, and the arc tube 1 is lit at high frequency by an inverter 2. The arc tube 1 and the inverter 2 are integrated by a housing portion, which is surrounded by a globe 4 and a cover 3, and a base 5 is attached.

図2は電球形蛍光ランプの発光管の展開図である。図において、発光管1は4本のU字管で構成され、発光管1の両端に電極8が設けられている。そして、発光部に主アマルガム6、補助アマルガム7を備えている。補助アマルガム7は電極8近傍に取り付けられ、放電路の中間部にも取り付けられている。   FIG. 2 is a development view of an arc tube of a bulb-type fluorescent lamp. In the figure, the arc tube 1 is composed of four U-shaped tubes, and electrodes 8 are provided at both ends of the arc tube 1. And the main amalgam 6 and the auxiliary | assistant amalgam 7 are provided in the light emission part. The auxiliary amalgam 7 is attached in the vicinity of the electrode 8 and is also attached to the middle part of the discharge path.

主アマルガム6と補助アマルガム7を用いたアマルガム方式の電球形蛍光ランプの光束立ち上がり特性は、図9に示すように、分単位での観察がなされているが、点灯直後の秒単位での光束立ち上がり特性を検討したものはない。   As shown in FIG. 9, the luminous flux rise characteristic of the amalgam type bulb-type fluorescent lamp using the main amalgam 6 and the auxiliary amalgam 7 is observed in units of minutes, but the luminous flux rises in seconds immediately after lighting. None of the properties have been studied.

そこで、電球形蛍光ランプ(EFA15)について、点灯直後の秒単位での光束立ち上がり特性を検討した。図3は電球形蛍光ランプ(EFA15)の光束立ち上がり特性を示す図である。図において、Phase1は点灯直後であり、50%弱の明るさの例を示しているが、この点灯直後の明るさは、点灯時の発光管内の水銀蒸気圧により決定されている。   In view of this, with respect to the bulb-type fluorescent lamp (EFA15), the luminous flux rising characteristics in seconds immediately after the lighting was examined. FIG. 3 is a diagram showing a luminous flux rising characteristic of a bulb-type fluorescent lamp (EFA15). In the figure, Phase 1 is immediately after lighting and shows an example of a brightness of less than 50%, but the brightness immediately after lighting is determined by the mercury vapor pressure in the arc tube at the time of lighting.

Phase2(点灯直後から1秒強の間)は蛍光体層に水銀蒸気が吸着し、水銀蒸気圧が低下する期間である。ここで、蛍光体層内表面積と管内水銀原子数の比(同蒸気圧では管内容積と同意)は管内径が細くなるほど小さくなるので、管内径が細くなるとPhase2の落ち込みが原理的に大きくなる。   Phase 2 (for a little over 1 second immediately after lighting) is a period in which mercury vapor is adsorbed on the phosphor layer and the mercury vapor pressure decreases. Here, the ratio between the phosphor layer inner surface area and the number of mercury atoms in the tube (which agrees with the tube volume at the same vapor pressure) becomes smaller as the tube inner diameter becomes smaller, so that the drop in Phase 2 becomes larger in principle as the tube inner diameter becomes smaller.

Phase3は、補助アマルガムからの水銀放出期で、電極近傍に設けられた補助アマルガムが輻射熱により加熱され、貯蔵した水銀を放出し、管内水銀蒸気圧を上昇させる。   Phase 3 is a mercury release period from the auxiliary amalgam, and the auxiliary amalgam provided in the vicinity of the electrode is heated by radiant heat to release the stored mercury and raise the mercury vapor pressure in the tube.

従来、消灯中の管内水銀蒸気圧は、アマルガム方式に蛍光ランプでは、主アマルガムによって決定されると言われていた。   Conventionally, it has been said that the mercury vapor pressure in the tube during extinction is determined by the main amalgam in an amalgam type fluorescent lamp.

図4は、液状水銀、主アマルガム、補助アマルガムの飽和水銀蒸気圧と周囲温度の関係を示す図である。例えば、常温(25℃)では、補助アマルガムの飽和水銀蒸気圧は1×10−4(Torr)[A点]、主アマルガムの飽和水銀蒸気圧は1×10−3(Torr)[B点]、液状水銀の飽和水銀蒸気圧は6×10−3(Torr)[C点]である。 FIG. 4 is a diagram showing the relationship between saturated mercury vapor pressure and ambient temperature of liquid mercury, main amalgam, and auxiliary amalgam. For example, at normal temperature (25 ° C.), the saturated mercury vapor pressure of the auxiliary amalgam is 1 × 10 −4 (Torr) [A point], and the saturated mercury vapor pressure of the main amalgam is 1 × 10 −3 (Torr) [B point]. The saturated mercury vapor pressure of liquid mercury is 6 × 10 −3 (Torr) [C point].

今回、消灯中の管内水銀蒸気圧は、補助アマルガム、及び主アマルガムの水銀捕獲容量と封入水銀量の関係により、離散的に変化する(図4のA点→B点→C点と上昇する)という仮説を立てた。   This time, the mercury vapor pressure in the tube during extinction varies discretely depending on the relationship between the mercury capture capacity of the auxiliary amalgam and the main amalgam and the amount of enclosed mercury (increases from point A to point B to point C in FIG. 4). I made the hypothesis.

図5は点灯直後の明るさに関する仮説を説明する図であり、以下の仮説を立てた。
(1)補助アマルガムの水銀捕獲容量>封入総水銀量、の場合は、点灯前の管内水銀蒸気圧は補助アマルガムが規制する。
(2)補助アマルガムの水銀捕獲容量<封入総水銀量、の場合は、点灯前の管内水銀蒸気圧は主アマルガムが規制する。
(3)封入総水銀量>主アマルガムの水銀捕獲容量+補助アマルガムの水銀捕獲容量、の場合は、点灯前の管内水銀蒸気圧は液状水銀が規制する。
この仮説が正しければ、(2)の補助アマルガムの水銀捕獲容量よりも封入総水銀量を多くすれば、点灯前の管内水銀蒸気圧は主アマルガムが規制し、主アマルガムの水銀蒸気圧は、図4に示したように、液状水銀の水銀蒸気圧に近いので、アマルガム方式の蛍光ランプの光束立ち上がり特性を改善することができる筈である。
FIG. 5 is a diagram for explaining a hypothesis regarding brightness immediately after lighting, and the following hypothesis was established.
(1) When the mercury capture capacity of the auxiliary amalgam is greater than the total mercury content, the auxiliary amalgam regulates the mercury vapor pressure in the tube before lighting.
(2) If the mercury capture capacity of the auxiliary amalgam is less than the total mercury content, the main amalgam regulates the mercury vapor pressure in the tube before lighting.
(3) In the case of the total mercury content> mercury capture capacity of the main amalgam + mercury capture capacity of the auxiliary amalgam, liquid mercury regulates the mercury vapor pressure in the tube before lighting.
If this hypothesis is correct, if the total mercury content is larger than the mercury capture capacity of the auxiliary amalgam in (2), the main amalgam regulates the mercury vapor pressure in the tube before lighting, and the mercury vapor pressure of the main amalgam is As shown in FIG. 4, since it is close to the mercury vapor pressure of liquid mercury, the luminous flux rise characteristic of an amalgam type fluorescent lamp should be improved.

そこで、上記仮説を検証するため、図6に示すようなFLS20SS/18(直管形蛍光ランプ)に補助アマルガムを片側に付けた実験用蛍光ランプを試作した。その実験用蛍光ランプについて、点灯直後、点灯2秒後の暗部の発生の有無を観察記録した。   In order to verify the above hypothesis, an experimental fluorescent lamp in which an auxiliary amalgam was attached to one side of FLS20SS / 18 (straight tube fluorescent lamp) as shown in FIG. 6 was prototyped. The experimental fluorescent lamp was observed and recorded for the presence or absence of dark areas immediately after lighting and 2 seconds after lighting.

その結果を、図7に示す。封入総水銀量を9.0[mg]と4.5[mg]、封入In量を8.8[mg]、4.4[mg]、2.2[mg]、1.1[mg]、無の組合せの10種類の試料について、点灯直後、点灯2秒後の暗部の発生の有無を観察記録した。
(1)[封入総水銀量/封入In量]が、0.51、1.02、0.51、2.00、2.05のものは、点灯直後、点灯2秒後の暗部の発生が有り、点灯2秒後では反補助アマルガム側に暗部が発生した。
(2)[封入総水銀量/封入In量]が、4.09、8.18のものは、点灯直後、点灯2秒後の暗部の発生は無かった。
(3)補助アマルガムを使用しない従来例は、当然ではあるが点灯直後、点灯2秒後の暗部の発生は無かった。
The result is shown in FIG. Encapsulated total mercury amount is 9.0 [mg] and 4.5 [mg], enclosed In amount is 8.8 [mg], 4.4 [mg], 2.2 [mg], 1.1 [mg] With respect to 10 kinds of samples having no combination, the presence or absence of the dark part immediately after lighting and after 2 seconds of lighting was observed and recorded.
(1) When [Encapsulated total mercury amount / Encapsulated In amount] is 0.51, 1.02, 0.51, 2.00, 2.05, a dark portion is generated immediately after lighting and after 2 seconds of lighting. Yes, after 2 seconds of lighting, a dark part occurred on the side of the anti-auxiliary amalgam.
(2) When [Encapsulated total mercury amount / Encapsulated In amount] is 4.09 or 8.18, no dark portion was generated immediately after lighting and 2 seconds after lighting.
(3) In the conventional example in which the auxiliary amalgam is not used, the dark part was not generated immediately after lighting and 2 seconds after lighting, as a matter of course.

上記のように、点灯直後の明るさに関する仮説が正しいことが立証された。点灯前に液状水銀が管内に存在するようにすれば、点灯直後の暗部の発生を無くすことができる。   As mentioned above, it was proved that the hypothesis about the brightness immediately after lighting was correct. If liquid mercury is present in the tube before lighting, it is possible to eliminate the occurrence of dark areas immediately after lighting.

上記検証は、FLS20SS/18(直管形蛍光ランプ)に補助アマルガムを片側に付けた実験用蛍光ランプで行ったが、封入総水銀量>補助アマルガムの水銀捕獲容量、具体的には、封入総水銀量/封入In量(重量比)≧4.09、とすれば、主アマルガムと補助アマルガムを用いたアマルガム方式の蛍光ランプにおいて、点灯前の管内水銀蒸気圧は主アマルガムが規制し、主アマルガムの水銀蒸気圧は液状水銀の水銀蒸気圧に近いので、点灯直後の暗部の発生を無くすことができる。   The above verification was performed with an experimental fluorescent lamp with an auxiliary amalgam attached to one side of FLS20SS / 18 (straight tube fluorescent lamp). The total mercury content> mercury capture capacity of the auxiliary amalgam, specifically, If mercury amount / encapsulated In amount (weight ratio) ≧ 4.09, in the amalgam type fluorescent lamp using the main amalgam and the auxiliary amalgam, the main amalgam regulates the mercury vapor pressure in the tube before lighting, and the main amalgam Since the mercury vapor pressure is close to the mercury vapor pressure of liquid mercury, the occurrence of dark areas immediately after lighting can be eliminated.

Embodiment 2. FIG.
FIG. 8 is a diagram showing the second embodiment and is a diagram showing a compact fluorescent lamp. In the first embodiment, the improvement of the luminous flux rise characteristic of the bulb-type fluorescent lamp has been described.
