【発明の詳細な説明】 産業上の利用分野 本発明はメタルハライドランプに関するものである。[Detailed description of the invention] Industrial applications The present invention relates to metal halide lamps.
従来の技術
近年、メタルハライドランプの小型化，低ワット化が進

組み込むことが困難となる。したがってこの場合、高圧
パルスを発生するイグナイタ内蔵の安定器で点灯される
ことが多い。Conventional technology In recent years, metal halide lamps have become smaller and have lower wattage.
This makes it difficult to incorporate a so-called starting aid mechanism, such as a glow lamp, into the lamp. Therefore, in this case, the lights are often lit using a ballast with a built-in igniter that generates high-voltage pulses.
発明が解決しようとする課題
しかし、小型・低ワットのメタルハライドランプでは、
ステム線間、およびステム線と外部導入線間の距離が短
くなるために、高圧パルスによって前記ステム線間また
はステム線と外部導入線間で放電が起こり、ランプが始
動しないという問題があった。Problems to be solved by the invention However, with small, low-wattage metal halide lamps,
Since the distance between the stem wires and between the stem wire and the external lead-in wire is shortened, there is a problem in that the high-voltage pulse causes discharge between the stem lines or between the stem wire and the external lead-in wire, and the lamp does not start.
本発明の目的は、高圧パルスに対するステム線と外部導
入線間の放電を防止し、確実に始動することのできるメ
タルハライドランプを提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a metal halide lamp which can be started reliably by preventing discharge between a stem wire and an external lead-in wire due to high voltage pulses.
課題を解決するための手段
本発明のメタルハライドランプは、内部に一対の電極が
設けられ、希ガスおよび金属ハロゲン化物が封入され、
かつ両端に封止部が設けられ、さらに各々の封止部から

貫通させた構成を有している。Means for Solving the Problems The metal halide lamp of the present invention is provided with a pair of electrodes inside, and is filled with a rare gas and a metal halide.
and sealing portions are provided at both ends, further comprising an arc tube led out from each sealing portion to the outside of the external lead-in wire, and a stem wire provided along the arc tube is connected to one of the external lead-in wires. At the same time, one end of a cylinder made of an insulating material is fixed to one end of the sealing part located far from the connection point between one of the external lead-in wires and the stem wire, and the other end of the cylinder is fixed. It has a configuration in which it is fixed to a base and the other of the external lead-in wires is passed through the cylinder.
作用
かかる手段を採用することにより、発光管の封止部から
外部に導出された外部導入線が、絶縁性材料からなる筒
内を貫通しベース内に至るため、ステム線は１本だけで
すみ、また前記外部導入線とステム線間には、絶縁性材
料からなる筒が介在するため、ステム線と外部導入線間
の絶縁性が向上することとなる。By adopting this method, the external lead-in wire led out from the sealed portion of the arc tube penetrates the inside of the cylinder made of insulating material and reaches the inside of the base, so only one stem wire is required. Moreover, since a cylinder made of an insulating material is interposed between the external lead-in wire and the stem wire, the insulation between the stem wire and the external lead-in wire is improved.

Along with scandium iodide and cesium iodide, xenon is filled in at 5 atm as a starting gas. Luminous tube 1
The inner diameter of is 2. 7 m, and the distance between the electrodes is 4.2 m. Further, sealing portions 3 and 4 are provided at both ends of the arc tube 1, and external lead-in wires 5.6 are led out from each sealing portion. A stem wire 7 provided along the arc tube 1 is welded to one of the external lead-in wires 5. and,
One end of a cylinder 4 made of an insulating material such as quartz and having an outer diameter of 4 m and a wall thickness of 1- is welded to one end of the sealing part 4 that is farthest from the connection point between the external lead-in wire 5 and the stem wire 7. A cylindrical base 9 made of heat-resistant resin is provided with a hole 10, into which the other end of the cylinder 8 is fitted, and is further fixed with a heat-resistant cement 11 mainly composed of alumina and silica.

。Effects of the Invention As explained above, according to the present invention, a pair of electrodes is provided inside, a sealing portion is provided at both ends, and an external lead-in wire is led out from each sealing portion. The stop portion includes an arc tube, connects a stem wire provided along the arc tube to one of the external lead-in wires, and is further away from a connection point between one of the external lead-in wires and the stem wire. By fixing one end of a tube made of an insulating material to one end of the tube, fixing the other end of the tube to a base, and passing the other side of the external lead wire through the tube, the distance between the stem wires is reduced when starting the lamp. Needless to say, since it is possible to prevent the occurrence of discharge between the external lead wire and the stem wire, it is possible to provide a metal halide lamp with good starting characteristics.
