The present invention relates to a self-starting short arc rare gas discharge lamp, particularly a self-starting short arc rare gas discharge lamp for direct current. Generally, to start a short arc noble gas discharge lamp, a very high high frequency voltage of 10 to 50 KV must be applied. On the other hand, to start a self-starting short-arc rare gas discharge lamp, a bridge wire connected to short-circuit both electrodes is fused, an arc light is generated, and the fusion energy generated at that time is used. By doing so, it is sufficient to apply a voltage of 100V or less. Such an electrode is made of a metal such as thorium tungsten, which has a low work function and easily emits heat electrons, and its tip has a conical shape to concentrate and stabilize the bright spot of the discharge. There is. However, when the bridging wire melts, the molten material adheres to the electrode tip, deforming the electrode tip, and making the electrode material different. actively moving between and
Discharge becomes unstable. Furthermore, due to the adhesion of the bridging wire melt, the sharpness of the tip of the electrode is lost, and the bright spot of the discharge is not concentrated, and the brightness of the bright spot is reduced, so that the amount of light is also reduced. The presence of bright spots of discharge is more noticeable in rare gas discharge lamps for DC lighting than in rare gas discharge lamps for AC lighting. Therefore, the inconvenience caused by the adhesion of molten material on the bridge wire is more significant in rare gas discharge lamps for direct current lighting. A rare gas discharge lamp for DC lighting has a cathode and an anode, and the bright spot of the discharge is on the cathode, so in the case of a self-starting short arc rare gas discharge lamp, there is a possibility that the bridge wire melt may adhere to the cathode. Must not be. The present invention has been made in view of the above-mentioned disadvantages, and it is an object of the present invention to provide a self-starting short-arc rare gas discharge lamp in which no melted bridge wire adheres to the cathode and stable discharge is achieved. The present invention includes an enclosure in which a rare gas is sealed;
The anode and cathode are fixedly arranged opposite to each other in this enclosure, and the body part located on the same side of each of the anode and cathode is supported so as to short-circuit the anode and cathode.The cross-sectional area is 1.25×10 -5 It consists of a bridging body of metal foil or metal wire of ~3.14×10 -4 cm 2 , the total length of the part where this bridging body can be fused is l (cm), and the shortest distance from the tip of the cathode to the bridging body is The present invention is characterized by a self-starting short arc discharge lamp that satisfies the condition 0.04≦r/l≦0.2, where r (cm). That is, the first feature of the structure of the present invention is that both ends of the bridging body are connected to the body of the electrode so as to be located on the same side, and unlike the conventional structure, there is no groove for accommodating the bridging body. There is no cross-linking, and the bridging bodies do not intersect. In the former type, it is extremely difficult to form a groove on the conical surface of the tip of the electrode, and in the latter type, the melt of the bridging body tends to adhere to the tip of the electrode. On the other hand, when both ends of the bridging body are located on the same side of both electrodes, it is not only easy to process, but also
Compared to electrodes in which the bridging bodies intersect, the melt of the bridging bodies is less likely to adhere to the tip of the electrode. Second, the bridging body should have a meltable partial cross-sectional area of 1.25×10 −5 to 3.14×10 −4 (cm 2 ). In the case of metal wire, this means that the diameter is
In the case of metal foil with a thickness of 0.0025 cm, the width corresponds to 0.005 to 0.12 cm. The reason why we set the lower limit of the cross-sectional area of the bridging body to 1.25 × 10 -5 cm 2 is that if it is smaller than this, the energy at the time of fusing is weak and it will not start automatically when filled with a rare gas of 10 atmospheres or more at room temperature. It's for a reason. Also, the upper limit of the cross-sectional area of the bridging body was set to 3.14×10 -4
( cm2 ) is that although the energy at the time of fusing is high, the applied voltage and current for fusing are correspondingly high. In other words, in a bridge body with a cross-sectional area of 3.14 x 10 -4 (cm 2 ), if the total length l of the part that can be fused is 0.3 cm, the instantaneous current at the time of fusion will be 600 A or more and it can be used in a lighting circuit. This may cause destruction of electronic components or damage to sealing parts. Here, the total length l of the bridging body of the part that can be fused means that in the bridging body welded to the bodies of both electrodes, both electrodes are short-circuited from the welding edge on the cathode side to the welding edge on the anode side. Refers to length. When the cross-sectional area is constant, the resistance value of the bridge body is determined by the length of the bridge body portion that can be fused. As an example of a bridging body, when the thickness is 0.0025 cm and the width is 0.0375 cm, the relationship between the total length of the bridging body in the portion that can be fused and the bridging body resistance value is as shown in FIG. Therefore, the fusing current of the bridge changes depending on the difference in the resistance value of the bridge. Furthermore, if the upper limit is exceeded, the amount of condensation and scattering of the melt in the bridge body increases accordingly, making it increasingly difficult to prevent the melt from adhering to the cathode tip. Due to the above reasons, the cross-sectional area is 1.25×10 -5 ~3.14
×10 -4 (cm 2 ) metal foil or metal wire bridge should be selected. Thirdly, the relationship between l and r must satisfy the condition of 0.04≦r/l≦0.2. If the overall length of the bridging body in the portion that can be fused is long, the amount of condensation and scattering of melt produced during fusing will also increase, so the bridging body must be supported at a position away from the cathode tip. but,
If it is placed too far from the cathode tip, there is an inconvenience that it will not start up automatically. Regarding the bridging body, the conditions for self-starting are (1) selecting a material with a large heat of fusion, (2) having a large cross-sectional area and long overall length to increase the fusing energy, (3) Furthermore, it is brought closer to the cathode and the cathode is heated by the energy generated during fusing. On the other hand, if the bridge body is brought too close to the cathode, adhesion of the melted bridge body to the tip of the cathode is unavoidable. The inventors determined the cross-sectional area of the bridge body suitable for a self-starting short-arc rare gas discharge lamp, the total length l (cm) of the bridge body in the part that can be fused, and the shortest distance r (cm) of the bridge body from the cathode tip. As a result of various experiments regarding cm), it was found that when 0.04≦r/l≦0.2, the starting performance was good and the problem of adhesion of the bridge melt to the cathode was solved. This formula is r and l
are in a proportional relationship, which means that as l becomes longer, r must be moved further away. That is,
When the value of r/l is less than 0.04, the starting performance is good, but the melt of the bridge body adheres to the cathode. On the other hand, when the value of r/l is greater than 0.2, the melt of the bridge does not adhere to the cathode, but it is too far away from the cathode, resulting in insufficient cathode heating and difficulty in starting. Next, examples of the present invention will be described. As shown in FIG. 2, the self-starting short arc rare gas discharge lamp used in the experiment consists of an enclosure 1, a cathode 2, an anode 3, and a bridge body 4 that short-circuits both electrodes. The bridging body 4 is connected to the body of each electrode so as to be located on the same side. The bridging body 4 is made of linear or foil molybdenum, and has a cross-sectional area of 1.25×10 -5 (cm 2 ).
For the three types, 7.85×10 -5 (cm 2 ) and 3.14×10 -4 (cm 2 ), the gap between both electrodes was 0.5 mm and 1.5 mm, the cathode was made of thorium tungsten, and the anode was made of thorium tungsten with a diameter of 1 mm. Various experiments were conducted using 2 mm of pure tungsten and setting the xenon gas pressure inside the enclosure 1 at 20 atm. The lighting device has a DC applied voltage of 80V and a short circuit current.
Lighted up at 14A. In FIG. 2, p indicates the tip of the electrode. The results are shown in the table below as an average value of data obtained by conducting experiments on each 15 electrodes when the gap between the two electrodes was 0.5 mm.

However, in the range of 7.85×10 −5 to 3.14×10 −4 cm 2 , although startup was good, a molten bridge material adhered to the cathode tip. When the value of r/l is 0.23, the cross-sectional area of the bridge is
7.85×10 -5 cm 2 was abnormal, but 1.25×10 -5 cm 2
In this case, the unstable discharge continued for as long as 1 second after startup, and the light went out due to an external shock. At 3.14×10 -4 cm 2 , the peak value of the lamp voltage at startup was as high as 30V. When the peak value of the lamp voltage approaches the power supply voltage, the discharge lamp turns off. Furthermore, when the value of r/l was 0.25, there was no adhesion of melted bridge material, but the engine did not start or
There were times when the lights went out in the middle. This was caused by insufficient thermionic emission from the cathode because the bridge reached the cathode and the thermal energy generated when the bridge melted did not heat the cathode. Furthermore, the results when the distance between both electrodes was 1.5 mm also had a similar tendency to the results in the table above. From the above results, from the viewpoint of starting and prevention of adhesion of the bridge melt to the cathode tip, it is possible to obtain a good self-starting short arc rare gas discharge lamp when 0.04≦r/l≦0.2 is satisfied. It is something that can be done. Furthermore, the same results as above were obtained when fuse 4' having the shape shown by the broken line in FIG. 2 was used. The reason for this is thought to be as follows. That is, this discharge lamp is lit horizontally with the bridge body side facing downward so that the cathode is efficiently heated by the thermal energy generated when the bridge body melts. As a result, the heat generated when the bridge member is melted is convected upward, and the cathode located above the bridge member is efficiently heated. Furthermore, the molten bridge body is in the direction of falling, and therefore the adhesion of the molten bridge body tends to be reduced. Therefore, the influence of differences in the shape of the bridging body and variations on startability is reduced. In other words, due to differences in the shape of the bridging body, r/
l is more important.
