摘要： A control circuit for a discharge lamp, which can improve the lighting performance of the discharge lamp while realizing low power consumption, and a light source device are provided. The resistance value of the variable resistor (RC1, RC2) is not switched to the low resistance (R02) for steady discharge at the fourth time t4, but is switched to the low resistance (R02) at the fifth time t5, after lowering of power supply to the filament. With such control, a change in the lamp impedance is absorbed sufficiently by the variable resistor while power supply to the filament is being lowered and, therefore, destabilization of discharge is reduced and the lighting performance is improved.

摘要： The present invention relates to a deuterium lamp with a structure to enable high-accuracy positioning with respect to a mounting object such as an analyzer. The deuterium lamp comprises a sealed container in which a light-emitting portion to emit a discharge light in a predetermined direction is stored. The sealed container is constituted by a hollow body portion in which the light-emitting portion is stored and a hollow guide portion which guides a discharge light from the light-emitting portion to a light exit window provided at its front end. The deuterium lamp further comprises an axis adjusting member fixed to the hollow guide portion while storing at least a part of the hollow guide portion and a sealing layer for fixing the hollow guide portion and the axis adjusting member to each other. In particular, the sealing layer makes it possible to fix the axis adjusting member to the hollow guide portion with the center axis of the axis adjusting member being made coincident with the emitting direction of a discharge light. Thereby, even when misalignment has occurred between the center axis of the hollow guide portion and the emitting direction of a discharge light due to a manufacturing error in manufacturing of the container, since the axis adjusting member itself is directly fixed to the mounting object, it becomes possible to fix said deuterium lamp to an analyzer or the like with the optical axis aligned at a high accuracy.
摘要翻译：本发明涉及具有能够相对于诸如分析仪的安装对象进行高精度定位的结构的氘灯。氘灯包括密封容器，其中存储有沿预定方向发射放电光的发光部分。密封容器由存储有发光部的中空主体部分和将发光部分的放电光引导到设置在其前端的光出射窗的中空导向部分构成。氘灯还包括固定到中空引导部分的轴线调节构件，同时存储中空引导部分的至少一部分和用于将中空引导部分和轴线调节构件彼此固定的密封层。特别地，密封层使得可以将轴调节构件固定到中空引导部分，同时使轴调节构件的中心轴线与放电灯的发射方向一致。因此，即使由于制造容器的制造误差而导致中空引导部的中心轴与放电光的发射方向之间发生偏移，由于轴调整部件本身直接固定在安装对象上，所以可以使所述氘灯以高精度对准的分析器等固定。

摘要： The present invention relates to a light source apparatus with a structure that improves the positioning precision of a gas discharge tube and facilitates gas discharge tube maintenance work. The light source apparatus has a lamp container housing the gas discharge tube, and an insulating socket member that is fixed in a state of being positioned with respect to the lamp container and that is housed in the lamp container together with the gas discharge tube. The insulating socket member has a plane contacting portion put in plane contact with a stem portion of the gas discharge tube, and a pin socket member into which at least one of stem pins, held in the stem portion is inserted in an electrically contacting state. By the corresponding stem pin being inserted in the pin socket member, the gas discharge tube is fixed in a manner enabling attachment and detachment with respect to the insulating socket member, and the precision of positioning of the gas discharge tube with respect to the lamp container is thereby improved dramatically. Also, because the insulating socket member fixes the gas discharge tube in a detachable state, detachment of the gas discharge tube is facilitated and consequently, exchange of the gas discharge tube and other maintenance work are facilitated.

摘要： The present invention relates to a light source apparatus with a structure that enables the brightness of a gas discharge tube to be stabilized and facilitates gas discharge tube maintenance work. The light source apparatus has a gas discharge tube, a lamp container housing the gas discharge tube, and a base on which the lamp container is fixed. The gas discharge tube is fixed via a heat insulating member to a portion of an outer shell of the lamp container, and the heat insulating member functions to reduce heat transfer between the lamp container and the gas discharge tube to reduce the influence of temperature change, outside the lamp container, on the gas discharge tube. The lamp container also has an attachment/detachment structure for enabling attachment and detachment of the portion of the outer shell on which the gas discharge tube is fixed via the insulating member, with respect to the remaining portion of the outer shell, and whereby the attachment/detachment structure facilitates gas discharge tube maintenance work.

摘要： At an initial stage of a discharge start, a shield electrode is connected to a ground potential via a bidirectional voltage trigger switch. Thereafter, when an electrical charge within the shield electrode flows to the ground potential, by being triggered with this potential, both terminals of the bidirectional voltage trigger switch are disconnected therebetween. Thus, at an initial stage of discharge, charging of the shield electrode is suppressed to suppress a decline in discharge, and in a sustained discharge, destabilization due to an unwanted discharge from the shield electrode to the anode can be suppressed, and using such an electrode automatically allows improving the lighting performance of a discharge lamp.

摘要： In a gas discharge tube there is carried out narrowing of the discharge path with cooperation of the first opening 20 and 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.
