The present invention relates to a small metal vapor discharge lamp and a lighting method thereof, and more particularly to a small metal vapor discharge lamp in which a high voltage bulb is applied at the time of restart, and a lighting method thereof.

2 with application of commercial power to enable immediate restart.
A high voltage of about 0 KV is applied. For this reason, the structure of a discharge lamp is, for example, as shown in FIG.
While creating a high vacuum inside, the lead wires 4a and 4b connected to the electrodes i3a and 3b of the arc tube 2 are drawn out to the electrodes i3 and 3b of the outer tube 1, respectively, to improve the insulation between the electrodes 3a and 3b, and to increase the # voltage. I was gaining sex.

なければならず、コスト的に不利であった。(Problems to be Solved by the Invention) The structure of the conventional small metal vapor discharge lamp as described above has the problem that the lamp size is long and large, and the musical instrument to which it is attached is also large. Furthermore, the outer tube must be made of an expensive material such as quartz, which is disadvantageous in terms of cost.

なり好ましくなかった。A small metal vapor discharge lamp as shown in FIG. 2 was also known as a lamp designed to accommodate an increase in lamp size. That is, the leads 194 a connected to the electrodes 3 a and 3 b of the arc tube 2 ,
4b is drawn out only to one end of the outer tube 1. Although this structure allows the total length of the outer tube 1 to be shortened, if a high voltage is applied to the electrodes 3a and 3b through the lead wires 4a and 4b, a discharge may occur between points A and B in the figure.
Not only could the lamp not be started, but the lamp could even be damaged. In order to prevent electrical discharge between points A and B, there is a technique of covering the lead wire 4b with an insulating tube 5 made of a glass tube or a ceramic tube, but the insulating tube 5 may vibrate and cause abnormal noise. This was undesirable because it blocked the light emitted from the arc tube 2 and emitted from the arc tube 2.
又輸送中に破損するなどの問題もあった。There were also problems such as damage during transportation.
（問題点を解決する為の手段）
本発明の小型金属蒸気放電灯は、筒状の透光性外管内に

成して配されていることを特徴としたものである。(Means for Solving the Problems) The small metal vapor discharge lamp of the present invention is a light-transmitting lamp in which an arc tube having main electrodes at both ends is housed in a cylindrical transparent outer bulb. It is characterized in that the central axis of the outer tube and the central axis of the arc tube are arranged at an angle.

上記の構成の小型金属蒸気放電灯を直流で点灯する場合

とが判った。In the above, it is preferable that the angle between the central axis of the translucent outer tube and the central axis of the arc tube be set to 15 to 60 degrees. It was found that the brightness obtained changes depending on the posture at the time.
そこで本発明の点灯方法は、発光管が鉛直となる姿勢と

。Therefore, the lighting method of the present invention is characterized in that the arc tube is placed in a vertical position, the upper electrode side of the arc tube is set as a negative pole, and a DC voltage is applied to light the lamp.

線による遮光も少なくすることができる。(Function) The small metal vapor discharge lamp of the present invention has a structure in which the arc tube is inclined inside the translucent outer tube, so the length of the translucent outer tube can be shortened accordingly, contributing to miniaturization. . In addition, since the distance between the lead wires connected to the main t8i at both ends of the arc tube is widened, the voltage performance is improved, making it possible to apply high voltage, and the distance from the light emitting part of the arc tube is also increased. It is also possible to reduce light shielding due to lead wires.

Moreover, metal cations, which are the main components of the luminescent substance, can also be concentrated in the core.
（実施例）
以下本発明の実施例を第３図以下の図面を参照して説明
する０図中１は筒状の透光性外管で。(Example) Examples of the present invention will be described below with reference to Figure 3 and the following drawings. In Figure 0, 1 is a cylindrical light-transmitting outer tube.

図中７はゲッタ（Ｂａ−ＡＩ系）である。A luminous tube 2 is housed inside the translucent outer tube 1, and the central axis a of the luminous tube 2 is approximately 4 mm from the central axis of the translucent outer tube 1.
The arc tube 2, which is tilted at 5 degrees, contains mercury (Hg) and argon (Ar), as well as predetermined amounts of diprosium iodide (DYI3) and thallium iodide (T-Rikko) in a quartz glass tube. and a metal halide-containing arc tube with a rating of 40W containing cesium iodide (CsI), and the terminals i3a and 3b at both ends are respectively connected to lead wires 4a and 4b introduced from the button stem b of the translucent outer tube l. 6
In the figure, 7 is a getter (Ba-AI type).
第４図および第５図は、他の実施例で、前記実施例と同
一の部材には同一符号を付して示した。FIGS. 4 and 5 show other embodiments, in which the same members as in the previous embodiment are denoted by the same reference numerals.

光管２とリード１１４ｂの間隔も必然的に拡がるので、
リード線４ｂによる遮光程度も少なくなり、太いリード
線の使用も可能となる。According to the above embodiment, it is possible to widen the distance between the lead wires 4a and 4b in the light-transmitting outer tube 1, and there is no risk of discharge in the lead wires even when a high voltage pulse is applied, and after the light is turned off, , it is possible to reliably restart immediately. In addition, since the distance between the arc tube 2 and the lead 114b inevitably increases,
The degree of light shielding caused by the lead wire 4b is also reduced, and thick lead wires can also be used.

より大きい角度とすると、透光性外管ｌの径を、それだ
け太くする必要があり、小型化の効果が少なくなる。It is considered appropriate that the angle between the central axis a of the light-transmitting outer tube 1 and the center fthb of the arc tube 2 is between 15 degrees and 60 degrees. 1
If the angle is smaller than 5 degrees, the effect of reducing the length of the light-transmitting outer tube 1 will be small and the distance between the lead wires 4a and 4b will become close, making it similar to the conventional type (FIG. 2). Furthermore, if the angle is greater than 60 degrees, the diameter of the light-transmitting outer tube 1 must be increased accordingly, and the effect of miniaturization will be reduced.
次に、上記実施例の小型金属蒸気故電灯を直流で点灯す

であった。又発光管２を水平とした場合には、１７００
ルーメンであった。尚、交流で点灯した場合には２１０
０ルーメンの明るさであった。Next, we investigated the relationship between the attitude of the arc tube 2 and the brightness when lighting the small metal vapor waste lamp of the above example with direct current, and the following results were obtained. That is, when the arc tube 2 is vertical and the upper electrode is a negative pole, 2
A brightness of 200 lumens (at 40 W) was obtained, whereas the brightness was 1650 lumens when the upper electrode was set as the positive pole. Also, when the arc tube 2 is horizontal, 1700
It was lumen. In addition, if the light is turned on by AC, 210
The brightness was 0 lumens.

、逆に上側電極をプラス極とすると、発光管の下部の温
度の低い所へ、添加物が集ってしまい発光特性が著しく
悪くなるものと考えられる。This is because when lighting with direct current, the main metal cations of the luminescent substance among the metal halides added inside the arc tube 2 are attracted to the vicinity of the negative electrode.For example, if the upper electrode is the negative electrode, This is thought to be due to the fact that dysprosium iodide and cesium iodide, which have lower vapor pressures, emit light to the upper part of the arc tube than in the case of alternating current. On the other hand, if the upper electrode is made a positive electrode, the additives will collect in the lower part of the arc tube where the temperature is low, and the light emitting characteristics will be significantly deteriorated.
従って、本発明の小型全屈蒸気放電灯を直流で点灯する
場合には、発光管を鉛直になるような点灯姿勢とすると
共に発光管の上側ＴＬ極をマイナス極とすることによっ
て、最大の発光特性が得られると言える。Therefore, when lighting the compact total bending vapor discharge lamp of the present invention with direct current, the maximum light emission can be achieved by setting the arc tube in a vertical lighting position and setting the upper TL pole of the arc tube as a negative pole. It can be said that the characteristics can be obtained.
