Abstract: PROBLEM TO BE SOLVED: To provide a gas discharge tube capable of increasing the amount of visible light from a visible light source passing a discharge path restriction part while maintaining the startability of discharge and preventing degradation of a service life of a positive electrode part, and to provide a light source device and liquid chromatograph.
SOLUTION: By setting one diameter D1 shorter than the other diameter D2 between two orthogonal diameters D1, D2 in an opening part 12a formed in the positive electrode part 12, the other diameter D2 can be made larger than an old diameter, and the one diameter D1 can be as large as the old diameter. Thus, the amount of the visible light from the visible light source passing the opening part 12a of the positive electrode part 12 of the gas discharge tube is increased by setting the other diameter D2 larger than the old diameter, and the startability of discharge is maintained and the degradation of the service life of the positive electrode part 12 is prevented by setting the diameter D1 as large as the old diameter.

Abstract: PROBLEM TO BE SOLVED: To provide a light source apparatus in which reliability of a deuterium lamp is improved.
SOLUTION: The light source apparatus 1 has a deuterium lamp to which an insulating member 26 is removably fixed. Stem pins 19a-19b projecting outward from a stem part 11b of the deuterium lamp 10 are electrically connected to a lead wire 28 via a pin socket 27 attached to the insulating member 26. In such light source apparatus 1, the force acting when the lead wire 28 is bent is transmitted to the pin socket 27. Consequently, the load acting on penetrated parts of the stem pins 19a-19b in a stem portion 11b is reduced, and generation of cracks in the stem portion pin 11b is inhibited, so that the life time of the deuterium lamp is extended.

Abstract: PROBLEM TO BE SOLVED: To provide a lamp house for a deuterium lamp that achieves a longer service lifetime, and a light source device having such a lamp house.
SOLUTION: A lamp house 30 for a deuterium lamp is configured as follows. In order to suppress a deterioration in light transmittance of a light emission window 19 provided in a light-guide cylindrical part 17, the lower temperature is better for the light-guide cylindrical part 17. On the other hand, if a light-emitting cylindrical part 15 is overcooled, cathode evaporation progresses too much and causes a failure in stable operation and a short service lifetime. Thus, the present invention is focused on this point. A heat-insulating member 33 is arranged between a first heat-dissipating part 31 covering the light-emitting cylindrical part 15 and a second heat-dissipating part 32 covering the light-guide cylindrical part 17 so as to prevent heat transfer between the first heat-dissipating part 31 and the second heat-dissipating part 32. By this, even if a countermeasure to maximally cool the second heat-dissipating part 32 is taken, the heat-insulating member 33 prevents the first heat-dissipating part 31 from being affected by cooling so as to prevent the light-guide cylindrical part 17 from being overcooled beyond expectation. Consequently, it achieves a longer service lifetime of a deuterium lamp.

Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp control circuit for improving lighting performance of a discharge lamp while achieving low power consumption, and to provide a light source device. SOLUTION: At a fourth time t4, resistance values for variable resistances R C1 , R C2 are kept unchanged over into a steady-discharge low resistance R02. At a fifth time t5 after power supplied to a filament lowers, they are changed over into the low resistance R02. In this control, the variable resistances sufficiently absorb a change of a lamp impedance when power supplied to the filament lowers, thus suppressing the destabilization of discharge and improving the lighting performance.
