Description
【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野） 本発明は始動装置を内蔵した金属蒸気放電灯に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a metal vapor discharge lamp with a built-in starting device.
（従来の技術）
高圧ナトリウムランプやメタルハライドランプはその始
動電圧が高いため、始動時に電源電圧にパルス電圧を重
畳する手段がとられる。(Prior Art) Since the starting voltage of high-pressure sodium lamps and metal halide lamps is high, a method is used to superimpose a pulse voltage on the power supply voltage at the time of starting.
このパルス電圧を発生させる手段として、たとえば点灯

人）と直列に接続してユニット化されている。As a means for generating this pulse voltage, for example, one is known in which a starter device consisting of a lighting tube and a resistor for limiting the glow current of the lighting tube is built into the outer bulb together with the arc tube. The above-mentioned resistor was originally formed of a filament, but since its length was quite long, it had to be made into a coil and stretched in a zigzag pattern, making it vulnerable to vibration and mechanical shock and reducing the reliability of the lamp. It was also the cause of the decline. To deal with this situation, we have developed a tungsten wire inside ceramic, which has excellent vibration resistance, can be compactly molded into the desired shape, and is suitable for installation in narrow spaces such as inside discharge lamps. JP-A-56-73856 discloses a means to replace such a ceramic resistor with a resistor embedded therein. Figure 3 shows a discharge lamp with a built-in starting device described in this publication. In Figure 1, (1) is the outer tube, (4) is the arc tube,
(8A) is a disc-shaped ceramic resistor, 00) is a lighting tube, and (9) is a normally closed bimetal switch for separating the starting circuit from the main lighting circuit after the discharge lamp is lit.
This bimetal switch (9) has a ceramic resistor (8
connected in series with people) to form a unit.
しかしながら、このような放電灯にあっても次のような
欠点があることが判った。すなわち、近年効率の低い白
熱電球に代えて高い効率を有する金属蒸気放電灯の使用
が注目されているが、このためには金属蒸気放電灯の小
形化が必要となる。However, it has been found that even such a discharge lamp has the following drawbacks. That is, in recent years, the use of high-efficiency metal vapor discharge lamps in place of low-efficiency incandescent lamps has attracted attention, but this requires miniaturization of metal vapor discharge lamps.
放電灯を小形化するには外管の小形化が欠かせない条件
で、外管を小形化すると一般に始動装置を収容する外管
ネック部も必然的に小さくせざるを得なくなる。In order to miniaturize a discharge lamp, it is essential to make the outer bulb smaller, and when the outer bulb is made smaller, the neck of the outer bulb, which generally accommodates the starter device, must also be made smaller.
一方、セラミック抵抗体はそれ自体が発熱するので、む
やみに小形化しようとすると破壊子ることかあり、その
小形化には限界がある。On the other hand, ceramic resistors themselves generate heat, so if you try to make them too small, you may end up destroying them, so there is a limit to how small they can be.
このため、上記従来の第３図示の放電灯の場合のように
９円板状のセラミック抵抗体（８人）を外管（１）の中

部（２）内の熱対流が悪くなってセラミック抵抗体（８
Ａ）が冷えにくくなる。For this reason, as in the case of the conventional discharge lamp shown in FIG. If you try to install it inside or on the upper end side, there will be restrictions on its size, or it will cover the upper end side of the outer tube neck section (2). For example, when the light is turned off, the outer tube neck section (2 ) due to poor thermal convection within the ceramic resistor (8).
A) becomes harder to get cold.
この結果セラミック抵抗体（８人）上に設けられ。As a result, ceramic resistors (8 people) were installed.
点灯中は開いているバイメタルスイッチ（９）の冷却速

へ放射される光が、外管ネック部（２）上端を覆うセラ
ミック抵抗体（８Ａ）で遮断されるので効率低下につな
がることにもなるし、さらに。The cooling rate of the bimetal switch (9), which is open during lighting, is also slow, resulting in a long recovery (closing) time, resulting in a long restart time. This drawback becomes particularly noticeable when the lamp is lit with the cap (3) side facing up. In addition, the light emitted from the 9 arc tube (4) toward the base (3) is blocked by the ceramic resistor (8A) that covers the upper end of the outer tube neck (2), leading to a decrease in efficiency. ,moreover.
点灯管０Ｑはセラミック抵抗体（８Ａ）の下側つまり外
管（１）の封止端部に近い位置に、しかも外管封止部（
１ａ）に対向する面積が広くなる横向き（外管中心軸に
直交する形。）の形で配設されているので。The lighting tube 0Q is located below the ceramic resistor (8A), that is, at a position close to the sealed end of the outer tube (1), and also close to the sealed end of the outer tube (1).
1a) because it is arranged horizontally (perpendicular to the central axis of the outer tube) with a larger area facing the outer tube.
外管封止工程において多量の熱を受けて損傷するおそれ
もある。There is also a risk of damage due to receiving a large amount of heat during the outer tube sealing process.

される光が遮断されて効率低下につながるとか。(Problems to be Solved by the Invention) In a conventional discharge lamp having a built-in starting device consisting of a bimetal switch, a ceramic resistor, and a lighting tube as described in 5 above, especially when the discharge lamp is miniaturized, Ceramic resistors not only have drawbacks such as being limited in size and not being able to cool down easily when the light is turned off, making it take longer for the bimetal switch installed on the resistor to return to normal and restarting the device. 2 The light emitted from the arc tube to the base is blocked, leading to a decrease in efficiency.
あるいは外管封止部側に近い位置に横向きに設置された
点灯管が、外管封止工程時の熱の影響で損傷を受けやす
い等の欠点があった。Another disadvantage is that the lighting tube, which is installed horizontally near the outer tube sealing section, is easily damaged by the heat generated during the outer tube sealing process.
そこで本発明は以上の各欠点を除去するもので。Therefore, the present invention aims to eliminate each of the above-mentioned drawbacks.

ことを目的とする。The object of the present invention is to provide a metal vapor discharge lamp with a built-in starting device, which does not require a long restart time, does not reduce light efficiency due to a ceramic resistor, and does not cause damage when sealing the outer tube of the lighting tube. do.

設置することにより構成される。(Means for Solving the Problems) The metal vapor discharge lamp of the present invention includes an arc tube inside the outer bulb, a normally closed bimetal switch connected in parallel with the arc tube,
A starting device is housed in which a ceramic resistor and a lighting tube are connected in series, and the ceramic resistor is formed into a plate shape and installed parallel to the central axis of the outer tube, and 9 lights are installed. It is constructed by placing a tube facing the flat part of a plate-shaped ceramic resistor.

動時間を短かくすることもできるし。(Function) With this configuration, the plate-shaped ceramic resistor is installed parallel to the central axis of the outer tube, so it is restricted by the size and cross-sectional area of the neck of the outer tube, making it unreasonably compact. Since this is no longer necessary, damage due to heat generation can be prevented, and since there is no need to cover the neck with a lid, thermal convection between the neck and the outer tube body, including the outer tube inner metal body, is improved. When the light is turned off, the ceramic resistor cools down more easily, so the bimetal switch provided on the ceramic resistor returns faster, and the restart time can be shortened.
さらにネック部方向（口金方向）への発光管からの放射
光を遮断することもないので効率を向上させることもで
きる。Furthermore, since the light emitted from the arc tube in the direction of the neck (direction of the base) is not blocked, efficiency can be improved.
そのうえ１点灯管もセラミック抵抗体の平面部と対向す

傷することも防止できる。Furthermore, since the one lighting tube is also installed at a position facing the flat part of the ceramic resistor, it can be prevented from being damaged by heat during the outer tube sealing process.
