Description

【0001】
【発明の属する技術分野】
本発明は、高圧ナトリウムランプ等の金属蒸気放電灯の始動回路の改良に関する。
【0002】
【従来の技術】
非線形強誘電性セラミックコンデンサー(以後FECという)をランプ内始動器の素子として有する高圧ナトリウムランプのうち、ランプ不点時に始動のためのパルス電圧の発生を停止させる機能(パルス停止機能)をもつランプは、図2に示すような回路構成図である。
図中1は発光管、2は外部補助導体、3はバイメタルスイッチ、4はFEC、5は半導体スイッチ、6はパルスの発生する位相を安定させるための抵抗、7はFEC加熱抵抗を兼ねる焦電流バイパス抵抗、8は破損時に回路に大電流が流れるのを防ぐ電流制御抵抗である。
【0003】
(抵抗の役割)
図2において、抵抗7は、焦電流をバイパスさせる作用(焦電流バイパス)と、ランプ不点時にFECの温度をキューリー温度以上に加熱してパルスの発生を停止させる作用(パルス停止機能)とを持っている。
ここで、焦電流とは、FEC4の温度がFECのキューリー温度を越えた際に発生する電流のことである。実際には、ランプ始動後ランプ内の温度が上昇し、バイメタルスイッチ3が開いた状態で、FEC4−抵抗7−抵抗6−抵抗8の回路上で流れる。
【0004】
なお、FEC4は抵抗7の熱が主に伝導により伝わることにより加熱される。抵抗7の抵抗値はランプ不点時に発生パルスを停止させるためFECをそのキューリー温度(約90℃)以上に加熱しなくてはならない。安定器の2次電圧が200Vクラスの場合には30〜100kΩ程度となる。
【0005】
(抵抗による発生パルス電圧の吸収)
ところで、抵抗7は、焦電流バイパスとパルス停止機能の他に、発生したパルス電圧を吸収する作用をもっている。そして、その抵抗値が低いほどパルス電圧を吸収する作用は大きい。
【0006】
図2の回路は、通常の場合完全に機能し、ランプ始動時、ランプ再始動時及びランプ異常時ともに問題は生じない。ここで、ランプ異常時とは、外球リーク、発光管リーク等の場合である。
つまり、ランプ始動時及びランプ再始動時は確実にランプを点灯させ、又、何らかの原因によりランプが始動しない場合は発生パルスを停止させ、更に、外球リーク、発光管リーク等の場合には自壊することにより発生パルスを停止させることができる。
【0007】
【発明が解決しようとする課題】
(100Vクラスにおける問題点)
しかし、ランプを点灯している電源(安定器の2次電圧)が100Vクラスにおいて、ランプ始動時及びランプ再始動時は確実にランプを点灯させ、かつ、何らかの原因によりランプが始動しない場合は発生パルス電圧を確実に停止させようとすると、抵抗7の抵抗値の選定が難しくなる。
【0008】
(100Vクラスにおける問題の理由)
これは、次の理由による。
パルス停止機能は、抵抗7を発熱させることにより実現しているが、その発熱量を確保するために、100Vクラスにおいては抵抗7の抵抗値を200Vクラスよりも低く設定しなければならない。
しかし、抵抗値が低くなれば抵抗7による発生パルス電圧の吸収は大きくなり、その結果発生パルス電圧が低くなってしまう。従って、ランプは始動しずらくなる。
【0009】
本発明は、上記に鑑みなされたもので、ランプを点灯している電源が100VクラスにおいてもFEC加熱用抵抗の抵抗値をあまり低くすることなしに、ランプ不点時にパルス電圧の発生を確実に停止させることができ、ランプ不点時にパルス電圧の発生を停止させる機能を有する金属蒸気放電灯を提供することを目的とする。
【0010】
【課題を解決するための手段】
前記目的を達成するために、非線形強誘電性セラミックコンデンサーをランプ内蔵始動器の素子として有し、かつランプ不点時に前記コンデンサーに並列に接続された加熱用抵抗によってそのキューリー温度以上に加熱することで、始動のためのパルス電圧の発生を停止させる機能を有し、前記コンデンサー加熱用抵抗に直列に、かつ前記コンデンサーに該加熱用抵抗を経て電導性部材であるタングステンコイルが結線されていることにより、前記セラミックコンデンサーを効率的に加熱してパルス停止を確実にすることを特徴とする。
【0011】
【作用】
前記構成により、FEC加熱用抵抗で発生した熱は効率的にFECに伝わりそれを加熱するので、発生パルス電圧を確実に停止させることができる。また、その結果、適正な抵抗値のFEC加熱用抵抗を採用することができるので、発生パルス電圧の吸収が少なくランプは始動しやすくなる。このことにより、FEC加熱用抵抗で発生した熱で効率的にFECを加熱することができるので発生パルス電圧が確実に停止し、適正な抵抗値のFEC加熱用抵抗を採用することができるのでランプは始動しやすくなる。
【0012】
【発明の実施の形態】
以下、本発明の実施例を図1に基づき説明する。図中11は透光性アルミナからなる発光管であり、両端に電極を封着している。このような発光管の外周には外部補助導体12が付設されている。又、発光管11と並列にバイメタルスイッチ13と、非線形強誘電性セラミックコンデンサー(FEC)14と、導体スイッチ15と、FEC破損時に回路に大電流が流れるのを防ぐ電流制御抵抗16とからなる直列回路が接続されている。更に、半導体スイッチ15と並列に発生するパルスの位相を安定させるための抵抗17が接続されている。更にまた、FEC14と並列にFECを加熱するための発熱体としてのFEC加熱用抵抗18と、該加熱用抵抗18に直列にかつ前記コンデンサーに該加熱用抵抗18を経て電導性部材であるタングステンコイル19が結線されている。
【0013】
次に、実験例について説明する。
表1に示すようなFEC加熱用抵抗値及び電導性部材の有無により構成した100Vクラス(40〜50W)の高圧ナトリウムランプを試作し、その始動特性及びパルス停止時間について調査した。
なお、電導性部材としてはタングステンコイル(MG=18.4、コイル長=10mm)を使用した。
その結果を、表1に示す。
(以下、余白)

【0015】
表1から明らかなように、本発明に係わるランプは始動特性が良好で、かつ、パルス停止時間も2分以内で良好であった。これは、非線形強誘電性セラミックコンデンサーに、該コンデンサー加熱用抵抗を経て電導性部材であるタングステンコイルが結線されていることにより、前記セラミックコンデンサーを効率的に加熱してパルス停止を確実にすることができる。
【0016】
【発明の効果】
以上のように本発明に係わる金属蒸気放電灯は、非線形強誘電性セラミックコンデンサーに、該コンデンサー加熱用抵抗を経て電導性部材であるタングステンコイルが結線されていることにより、発生した熱は効率的にFECに伝わり、発生パルスを確実に停止させることができる。その結果、適正な抵抗値のFEC加熱用抵抗を採用することができ、発生パルス電圧の吸収が少ないので、ランプは始動しやすくなる。そして、電源が100VクラスのランプにおいてもFEC加熱用抵抗の抵抗値を低くすることなしに、ランプ不点時にパルス電圧の発生を確実に停止させることができ、ランプ不点時にパルス電圧の発生を停止させる機能を有する金属蒸気放電灯が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a starting circuit of a metal vapor discharge lamp such as a high pressure sodium lamp.
[0002]
[Prior art]
Among high-pressure sodium lamps having a non-linear ferroelectric ceramic capacitor (hereinafter referred to as FEC) as a starter element in the lamp, a lamp having a function (pulse stop function) for stopping generation of a pulse voltage for starting when the lamp is unsuccessful These are circuit block diagrams as shown in FIG.
In the figure, 1 is an arc tube, 2 is an external auxiliary conductor, 3 is a bimetal switch, 4 is FEC, 5 is a semiconductor switch, 6 is a resistor for stabilizing the phase of pulse generation, and 7 is a pyroelectric current that also serves as an FEC heating resistor. A bypass resistor 8 is a current control resistor for preventing a large current from flowing through the circuit when it is damaged.
[0003]
(Role of resistance)
In FIG. 2, the resistor 7 has an action of bypassing the pyroelectric current (pyroelectric current bypass) and an action of stopping the generation of pulses by heating the FEC temperature to be equal to or higher than the Curie temperature when the lamp is not operating (pulse stop function). have.
Here, the pyroelectric current is a current generated when the temperature of the FEC 4 exceeds the Curie temperature of the FEC. Actually, after the lamp is started, the temperature in the lamp rises and flows on the circuit of FEC4-resistance 7-resistance 6-resistance 8 with the bimetal switch 3 opened.
[0004]
The FEC 4 is heated when the heat of the resistor 7 is mainly transmitted by conduction. The resistance value of the resistor 7 has to heat the FEC above its Curie temperature (about 90 ° C.) in order to stop the generated pulse when the lamp is unsuccessful. When the secondary voltage of the ballast is 200V class, it is about 30 to 100 kΩ.
[0005]
(Absorption of generated pulse voltage by resistance)
By the way, the resistor 7 has an action of absorbing the generated pulse voltage in addition to the pyroelectric current bypass and the pulse stop function. And the effect | action which absorbs a pulse voltage is so large that the resistance value is low.
[0006]
The circuit of FIG. 2 is fully functional in normal cases, and does not cause any problems during lamp start, lamp restart, or lamp abnormality. Here, the lamp abnormality time is a case of an outer bulb leak, arc tube leak or the like.
In other words, when starting the lamp and restarting the lamp, the lamp is turned on reliably. If the lamp does not start for some reason, the generated pulse is stopped. By doing so, the generated pulse can be stopped.
[0007]
[Problems to be solved by the invention]
(Problems in the 100V class)
However, when the power source (ballast secondary voltage) that is lighting the lamp is 100V class, the lamp is turned on reliably when the lamp is started and when the lamp is restarted, and the lamp does not start for some reason. If the pulse voltage is surely stopped, it is difficult to select the resistance value of the resistor 7.
[0008]
(Reason for problems in the 100V class)
This is due to the following reason.
The pulse stop function is realized by causing the resistor 7 to generate heat. In order to secure the amount of heat generation, the resistance value of the resistor 7 must be set lower than that of the 200 V class in the 100 V class.
However, if the resistance value decreases, the absorption of the generated pulse voltage by the resistor 7 increases, and as a result, the generated pulse voltage decreases. Therefore, the lamp is difficult to start.
[0009]
The present invention has been made in view of the above. Even when the power source lighting the lamp is 100 V class, the pulse voltage is reliably generated at the time of lamp failure without reducing the resistance value of the FEC heating resistor so much. An object of the present invention is to provide a metal vapor discharge lamp that can be stopped and has a function of stopping generation of a pulse voltage when the lamp is unsuccessful.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a non-linear ferroelectric ceramic capacitor is provided as an element of a starter with a built-in lamp, and when the lamp is unsuccessful, it is heated above its Curie temperature by a heating resistor connected in parallel to the capacitor. The tungsten coil, which is a conductive member, is connected in series to the capacitor heating resistor and to the capacitor via the heating resistor. Thus, the ceramic capacitor is efficiently heated to stop the pulse reliably.
[0011]
[Action]
With the above configuration, the heat generated by the FEC heating resistor is efficiently transferred to the FEC and heated, so that the generated pulse voltage can be stopped reliably. As a result, an FEC heating resistor having an appropriate resistance value can be adopted, so that the generated pulse voltage is hardly absorbed and the lamp is easily started. As a result, the FEC can be efficiently heated by the heat generated by the FEC heating resistor, so that the generated pulse voltage is surely stopped, and the FEC heating resistor having an appropriate resistance value can be adopted. Is easier to start.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIG. In the figure, 11 is an arc tube made of translucent alumina, and electrodes are sealed at both ends. An external auxiliary conductor 12 is attached to the outer periphery of such an arc tube. In series with the arc tube 11, a bimetal switch 13, a non-linear ferroelectric ceramic capacitor (FEC) 14, a conductor switch 15, and a current control resistor 16 that prevents a large current from flowing through the circuit when the FEC is broken. The circuit is connected. Further, a resistor 17 for stabilizing the phase of the pulse generated in parallel with the semiconductor switch 15 is connected. Furthermore, an FEC heating resistor 18 as a heating element for heating the FEC in parallel with the FEC 14, and a tungsten coil which is a conductive member in series with the heating resistor 18 and through the heating resistor 18 to the capacitor. 19 is connected.
[0013]
Next, experimental examples will be described.
A 100V class (40 to 50 W) high-pressure sodium lamp constructed according to the resistance value for FEC heating and the presence or absence of a conductive member as shown in Table 1 was prototyped, and its starting characteristics and pulse stop time were investigated.
A tungsten coil (MG = 18.4, coil length = 10 mm) was used as the conductive member.
The results are shown in Table 1.
(Hereinafter, blank space)
[0014]
[Table 1]
Figure 0003630203
[0015]
As is apparent from Table 1, the lamp according to the present invention had good starting characteristics and good pulse stop time within 2 minutes. This is because the tungsten coil, which is a conductive member, is connected to the nonlinear ferroelectric ceramic capacitor through the capacitor heating resistor, thereby efficiently heating the ceramic capacitor to ensure pulse stopping. Can do.
[0016]
【The invention's effect】
As described above, the metal vapor discharge lamp according to the present invention efficiently generates heat by connecting a tungsten coil, which is a conductive member, to a nonlinear ferroelectric ceramic capacitor via the capacitor heating resistor. Therefore, the generated pulse can be surely stopped. As a result, an FEC heating resistor having an appropriate resistance value can be adopted, and the generated pulse voltage is less absorbed, so that the lamp can be easily started. Even in a lamp with a power supply of 100 V class, the generation of the pulse voltage can be reliably stopped when the lamp is unspotted without lowering the resistance value of the FEC heating resistor. A metal vapor discharge lamp having the function of stopping is obtained.
