초고압 방전등Ultra high pressure discharge lamp

제1도는 아르곤 개스분압과 방전 개시전압과의 관계 그래프.1 is a graph showing the relationship between argon gas partial pressure and discharge start voltage.

제2도는 아르곤 개스분압과 전극 간격의 적에 대한 방전 개시 전압의 관계 그래프이다.2 is a graph showing the relationship between the argon gas partial pressure and the discharge start voltage with respect to the product of the electrode intervals.

본 고안은 초고압 방전등에 관한 것으로서, 더욱 상세하게는 소형 초고압 수은등에 관한 것이다.The present invention relates to an ultra-high pressure discharge lamp, and more particularly to a small ultra-high pressure mercury lamp.

종래의 초고압 수은등은 발광관 내에 수은(Hg)-아르곤(Ar)을 사용하여 방전되는데, 이때의 발광관 내의 초기 진공도는 4x10-5Torr 이상 배기시킨 상태로 시작하여 수은등의 전극 간격 길이는 d=30mm, 내경(Bore)은 ψ-2mm로 하여 사용하였다.Conventional ultra-high pressure mercury lamps are discharged by using mercury (Hg) -argon (Ar) in the light tube. At this time, the initial vacuum degree in the light tube starts with exhaust of 4x10 -5 Torr or more, and the electrode gap length of the mercury lamp is d = 30 mm and Bore were used as ψ-2 mm.

이때의 초고압 수은등은 내부기압이 100기압 이상이고, 1400-1500℃의 고온으로 동작한다.At this time, the ultra-high pressure mercury lamp has an internal pressure of 100 atm or higher and operates at a high temperature of 1400-1500 ° C.

또한, 초고압 수은등의 분광 특성의 연색성이 좋아 광화학 반응용, 의학용, 장거리 조명용, 사진제판용 광원등으로 이용되고 있다.In addition, the color rendering property of the ultra-high pressure mercury lamp has good color rendering property and is used as a light source for photochemical reaction, medicine, long-distance illumination, photolithography and the like.

그러나 초고압 수은등의 제작과정에서 아르곤 개스분압에 대하여는 종래의 기술사상들이 노우하우로 되어 있기 때문에 제작시 수은등의 효과가 충분히 나타날 수 있도록 내부전압이 100 기압 이상 되게 하고, 온도가 너무 상승되어 시동 개시될 때, 또는 동작중에 파괴되지 않도록 하는 등의 조건을 만족시켜 제작하기 어렵고, 이와 같이 제작되어도 초고압 수은등의 사용을 극대화 시키기에는 어려움이 많은 문제점이 있다.However, in the manufacturing process of ultra-high pressure mercury lamps, the conventional technical ideas are known as know-how about argon gas partial pressure, so that the internal voltage is over 100 atm so that the mercury lamp can be fully produced during the manufacturing process, and the temperature is too high to start. When it is difficult to produce the conditions, such as not to be destroyed during or during operation, there are a lot of problems to maximize the use of ultra-high pressure mercury lamp even if produced in this way.

따라서, 본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 발광관 내의 수은-아르곤을 사용하여 방전할 때, 아르곤 개스의 분압과 전극간격의 적에 대하여 방전개시의 전압과의 관계를 규명함으로써 안정된 방전 현상을 하도록 하는 초고압 방전등을 제공하는데 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to discharge with respect to the partial pressure of the argon gas and the enemy of the electrode interval when discharging using mercury-argon in the light emitting tube It is to provide an ultra-high voltage discharge lamp that makes a stable discharge phenomenon by identifying the relationship with the voltage of the start.

상기한 바와 같은 본 고안의 목적을 달성하기 위하여, 본 고안은 초고압 수은등에 있어서, 아르곤 개스분압과 전극간격(Arc Length)의 적(積)이 8-16(mbar,cm) 범위에서 방전되게 한 것을 특징으로 하는 초고압 방전등을 제공한다.In order to achieve the object of the present invention as described above, the present invention is designed to allow the discharge of argon gas partial pressure and electrode length in the ultra-high pressure mercury lamp to be discharged in the range of 8-16 (mbar, cm). It provides an ultra-high pressure discharge lamp characterized in that.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

제1도는 전압과의 관계 그래프를 나타낸 것으로서, 초고압 수은등의 발광관 내의 초기 진공도를 4x10-5Torr 이상 배기시키고, 전극 간격은 d=30mm, φ-2mm로 설정한 후 아르곤 가스분압 변화에 따른 방전개시 전압을 나타낸 것이다.1 is a graph showing the relationship with the voltage, the initial vacuum degree in the light tube of the ultra-high pressure mercury lamp is exhausted more than 4x10 -5 Torr, the electrode interval is set to d = 30mm, φ-2mm, and then discharged according to the change of argon gas partial pressure The starting voltage is shown.

도면중 실선은 적정커브이고, 점선은 실험데이타로 실험데이타는 표 1에 나타내었다.In the figure, the solid line is the appropriate curve, the dotted line is the experimental data, and the experimental data are shown in Table 1.

[표 1]TABLE 1

상기 표 1에 나타낸 실험 데이터에서 아르곤 분압은 2-6mbar 구간에서 방전 개시전압은 560-900V 정도인 것을 알 수 있으며, 이 구간에서는 아르곤 개스의 방전이 가장 용이하게 일어난다.In the experimental data shown in Table 1, the partial pressure of argon was found to be about 560-900 V in the discharge start voltage in the 2-6 mbar section, and the discharge of the argon gas occurred most easily in this section.

제2도는 아르곤 개스분압과 전극간격의 적에 대한 방전개시 전압과의 관계 그래프를 나타낸 것으로서, 제1도의 아르곤 개스분압에 전극 간격을 곱한 것이다.FIG. 2 is a graph showing the relationship between the argon gas partial pressure and the discharge initiation voltage with respect to the product of the electrode spacing. The argon gas partial pressure in FIG. 1 is multiplied by the electrode spacing.

즉, 아르곤 개스분압과 전극 간격과의 적(積)이 8-16(mbar, cm) 범위에서 방전이 가장 용이하다.In other words, the discharge between the argon gas partial pressure and the electrode spacing is most easily in the range of 8-16 (mbar, cm).

상기한 바와 같이 본 고안에 의하면 초고압 방전등의 아르곤 개스분압과 전극간격에 대한 방전 개시전압과의 관계를 규명하므로써 방전 현상을 이용한 안정된 초고압 방전등을 개발할 수 있는 효과가 있다.As described above, according to the present invention, the relationship between the argon gas partial pressure of the ultra high voltage discharge lamp and the discharge start voltage for the electrode interval is investigated, thereby making it possible to develop a stable ultra high pressure discharge lamp using the discharge phenomenon.
