Light Source Device
First Claim
1. A light source apparatus comprising:
- a gas discharge tube, having a stem portion that holds a plurality of stem pins in penetrating states;
a lamp container housing said gas discharge tube; and
an insulating socket member disposed between said gas discharge tube and an inner wall of said lamp container and being fixed in a state of being positioned with respect to said lamp container,wherein said insulating socket member is comprised of an electrically insulating material and, as a structure for fixing said gas discharge tube in a detachable state, has;
a plane contacting portion, having an electrically insulating property, put in plane contact with said stem portion of said gas discharge tube; and
a pin socket member provided in correspondence to at least one of said stem pins and in which the corresponding stem pin is inserted in an electrically connected state.

Abstract
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.
