摘要： This portable light source apparatus accommodates a deuterium lamp 10 in a lamp box 42 and, at the same time, in a housing 41 in order for the influence of temperature changes in the outside air to become very small. Namely, the deuterium lamp 10, which is susceptible to changes in temperature, is enveloped not only by the lamp box 42 but also by the housing 41, thereby being accommodated in a double shield structure. Further, it has been known that ozone is generated when ultraviolet rays are emitted in the air. Therefore, a light guide tube 70 for extending a light exit opening 69 of the lamp box 42 is provided, so that cooling winds do not traverse the ultraviolet rays. As a result, ozone is restrained from occurring in the part where the ultraviolet rays occur within the housing 41, whereby the emitted light is appropriately kept from fluctuating due to the occurrence of ozone.

摘要： A discharge lamp comprises: a housing including a dielectric part which is formed of a dielectric material and has a light transmission region for transmitting light, and a main body which together with the dielectric part forms a discharge gas sealing space in which discharge gas is sealed; an electron discharge source arranged facing the light transmission region in the discharge gas sealing space; a discharge path limiting member which separates the electron discharge source from the light transmission region in the discharge gas sealing space and has an electron pass-through hole for electrons discharged from the electron discharge source to pass through; and an external electrode which is arranged on the outside of the housing so as to face the electron discharge source with the dielectric part therebetween, and has an opening for the light transmitted through the light transmission region to pass through.

摘要： At an early period of a discharge start, a shield electrode is connected with the ground potential through a bidirectional voltage trigger type switch. Subsequently, electric charges in the shield electrode flow through the ground potential, and both terminals of the bidirectional voltage trigger type switch are cut off by this potential as a trigger. Thus, at the early period of the discharge, the suppression of static electrification of the shield electrode restrains the reduction of discharge. During the period to maintain the discharge, the lack of stability can be suppressed by a reluctant discharge from the shield electrode to the anode. The use of such an element automatically improves a turn-on characteristic of the discharge lamp.

摘要： A gas discharge tube 10 of the present invention generates an electric discharge between an anode part 24 and a cathode part 56 disposed inside a sealed container 12 in which gas has been contained. The gas discharge tube 10 comprises an electric discharge path restricting part 28 which is cylindrical and disposed between the anode part and the cathode part, and which has a throughhole 42 for narrowing an electric discharge path between the anode part and the cathode part; and an electric discharge shielding part 50 which is disposed to surround the electric discharge path restricting part so as to restrict an electric discharge from the outer peripheral surface of the electric discharge path restricting part to the cathode part, and which is electrically isolated from the electric discharge path restricting part. The end part of the electric discharge path restricting part on the cathode part side projects beyond a surface of the electric discharge shielding part on the cathode side by a predetermined amount "P" of projection. With this structure, a high density electron region is formed exclusively in a part of the throughhole of the electric discharge path restricting part on the cathode side, thereby ensuring the generation of a startup discharge.

摘要： In the gas discharge tube according to the present invention, there is carried out narrowing of the discharge path with cooperation of the first opening 20 and the second opening 12 in order to obtain higher luminance of light. Further, in order to maintain excellent starting-properties of a lamp even if the discharge path is narrowed, a predetermined voltage is applied to a second discharge path limit portion 11 externally. Thereby, a positive or active starting discharge is produced in such a manner as to pass through the first opening 20. Further, the second opening 12 is comprised of not only a straight section 13 extending in a direction of an optical axis Y, but also a spread section 14 extending from an end portion of the straight section 13 toward the first opening 20. The spread section 14 has a function of improving the starting properties of the lamp and forms an arc ball, and the straight section has a function of improving a plasma density. Thereby, discharge at a starting time is made easy to pass through the second discharge path limit portion 11. As a result, a rapid start of discharge between a cathode 23 and an anode portion 8 is achieved in the second discharge path limit portion 11, and that contributes to proper generation of an arc ball after lighting.

摘要： A gas discharge tube 10 of the present invention generates an electric discharge between an anode part 24 and a cathode part 52 disposed inside a sealed container 12 in which gas has been sealed. The gas discharge tube 10 includes an electric discharge path restricting part 28 which is cylindrical and disposed between the anode part and the cathode part, and which has a throughhole 46 for narrowing an electric discharge path between the anode part and the cathode part; and a supporting part 30 which supports the electric discharge path restricting part and which is electric insulating. The electric discharge path restricting part is provided at its tip portion with a projecting part 44 which is cylindrical and projects toward the cathode part side. Letting the outer diameter and height of the projecting part 44 be "D" and "H," respectively, then D/H is in the range of 0.5 to 2.0. With this structure, it is possible to generate an intense electric field in the vicinity of the tip of the projecting part. This can decrease a startup voltage, thereby ensuring the generation of an electric discharge.
