본 고안은 초고압 수은등의 발광관에 관한 것이다.The present invention relates to a light tube of ultra-high pressure mercury lamp.
일반적으로 초고압 수은등이 발광하게되면 약 1000℃의 고온으로 상승된다. 이경우, 내부의 초고압에 견디도록하기 위하여, 외부관은 주로 석영 유리를 사용하고 있다. 종래에는 외부관과 텅스텐 전극사이의 봉지는, 열팽창 계수가 전극과 비슷한 재질의 중간 유리로써 행하고 있다.In general, when the ultra-high pressure mercury lamp emits light, it is raised to a high temperature of about 1000 ° C. In this case, in order to withstand the very high pressure inside, the outer tube mainly uses quartz glass. Conventionally, sealing between an outer tube and a tungsten electrode is performed with the intermediate glass of the material whose thermal expansion coefficient is similar to an electrode.
그 이유는 석영 유리와 텅스텐 전극의 열 팽창 계수에 있어서, 10-1정도의 차이를 나타내므로 약 1000℃의 고온으로 되었을때, 봉지의 신뢰도가 저하하기 때문이다. 따라서, 제1도의 도시와 같이, 중간유리(G)를 석영유리판(a)와 텅스텐 전극(b)사이에 개재시켜 봉지하는 방식을 행하고 있다.The reason is that the thermal expansion coefficient of quartz glass and tungsten electrode shows a difference of about 10 −1, so that the reliability of the encapsulation decreases when the temperature is about 1000 ° C. Accordingly, as shown in FIG. 1, the intermediate glass G is sealed between the quartz glass plate a and the tungsten electrode b.
그러한, 이와같이 중간유리(C)를 개재시켜 수은등을 제작하게되면 이 부분이 고압에 약하여 수명이 짧아지는 문제점이 생기고 봉지 공정도 복잡하여 생산성 저하의 한 요인이 되기고 한다.If such a mercury lamp is produced through the intermediate glass (C) as described above, this part is weak to high pressure, resulting in a problem of shortening the life, and the encapsulation process is complicated, thereby causing a decrease in productivity.
또한, 외부도입선부가 텅스텐전극(b)로 사용됨에 따라 발생되는 파손을 방지하기 위하여 지지스프링등의 지지장치를 추가해야 하는 등의 문제점도 야기된다.In addition, in order to prevent breakage caused when the external lead wire is used as the tungsten electrode (b), there is also a problem such as adding a support device such as a support spring.
본 고안은 이와같이 종래의 제반 문제점을 해소가기 위하여 안출한 것으로써, 전극의 구조를 3단으로하여 중간유리의 사용을 생략함과 아룰러 전극지자장치를 필요로 하지 않는 초고압 수은등의 발광관을 제공하고자 함이 그 목적인 것이다.The present invention has been devised to solve all the problems of the related art, and the structure of the electrode has three stages, eliminating the use of intermediate glass, and providing a light tube of ultra-high pressure mercury lamp that does not require an all-around electrode geomagnetism device. The purpose is to.
이하 본 고안의 구성을 첨부된 도면에 의하여 좀더 상세히 기술하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in more detail with reference to the accompanying drawings.
제2도에 도시한 바와같이, 니켈을 주성분으로하는 리이드선(1)(1')와 니켈-철-코발트 합금으로 이루어지는 봉지선(2)(2') 및 텅스턴을 주성분으로 하는 필라멘트(3)이 상호 융착되어 전극(G)가 형성된다.As shown in FIG. 2, lead wires 1 (1 ') containing nickel as a main component, encapsulation wires (2) (2') composed of nickel-iron-cobalt alloys, and filaments containing tungsten as a main component ( 3) are fused to each other to form an electrode (G).
전기한, 전극(G)는 석영유리로 형성되는 발광관(4)에 함입되어 봉지선(2) 및 (2')가 발광관(4)의 봉지부(5)(5')에 봉지되고, 필라멘트(3)은 발광관(4)의 봉지부(5)(5')에 봉지되고, 필라멘트(3)은 발광관(4)내에 위치되어 발광토록하며, 리이드선(1) 및 (1')는 발광관(4)의 외부로 노출시켜 전원과 연결가능케 구성된다.As described above, the electrode G is embedded in the light emitting tube 4 formed of quartz glass, and the sealing lines 2 and 2 'are encapsulated in the encapsulation portions 5 and 5' of the light emitting tube 4, respectively. , The filament 3 is encapsulated in the encapsulation portion 5, 5 ′ of the light emitting tube 4, the filament 3 is located in the light emitting tube 4 to emit light, and the lead wires 1 and 1 ') Is exposed to the outside of the light emitting tube 4 is configured to be connected to the power source.
이와같이 구성되는 본 고안의 작용효과를 기술하면 다음과 같다.Referring to the effect of the present invention is configured as described as follows.
석영유리로 이루어지는 발광관(4)의 봉지부(5)(5')에 니켈-철-코발트 합금인 봉지선(2)및(2')가 위치하고 이것과 석영유리의 열팽창 계수는 5X10-7㎜/℃로동일하기 때문에 종래와 같이 중간유리를 사용하지 않고 석영유리만으로 봉지가 가능케된다. 따라서 초고압에 의한 취약부분이 생기지 않게 된다.Encapsulation lines 2 and 2 ', which are nickel-iron-cobalt alloys, are placed in the encapsulation portions 5 and 5' of the light emitting tube 4 made of quartz glass, and the coefficient of thermal expansion of the quartz glass is 5X10 -7. Since it is the same at mm / ° C, sealing is possible only with quartz glass without using an intermediate glass as in the prior art. Therefore, the weak part by the ultra-high pressure does not occur.
또한, 리이드선(1) 및(1')는 텅스텐보다 인장강도가 큰 니켈을 주성분으로 하고 있기 때문에 부러짐등을 방지하는 지지장치를 필요로 하지 않게된다.Further, since the lead wires 1 and 1 'mainly contain nickel having a greater tensile strength than tungsten, no support device for preventing breakage or the like is required.
이상과 같이 본 고안에 의한 초고압 수은등의 발광관은 중간유리를 사용하지 않아도 전극의 봉지를 용이하게 실시할 수 있으며, 전극의 리이드선을 지지하는 지지장치를 필요로 하지 않는 유용한 고안인 것이다.As described above, the light emitting tube of the ultra-high pressure mercury lamp according to the present invention can be easily encapsulated without using an intermediate glass, and is a useful design that does not require a support device for supporting the lead wire of the electrode.
