Light source device
First Claim
1. A light source apparatus comprising:
- a gas discharge tube generating light with a predetermined wavelength and having stem pins that protrude from a bottom surface thereof;
a lamp container housing said gas discharge tube; and
a base having a surface on which said lamp container is fixed,wherein said lamp container comprises;
a lamp fixing portion constituting a part of an outer shell of said lamp container;
a light emitting portion allowing light from said gas discharge tube housed therein to pass through toward the exterior of said lamp container;
a heat insulating member housed inside said lamp container, together with said gas discharge tube, said heat insulating member having a first surface being in direct contact with the bottom surface of said gas discharge tube, a second surface being in direct contact with an inner side surface of said lamp fixing portion, and through holes each communicating between the first and second surfaces and housing at least a part of said each stem pin, whereby said gas discharge tube is fixed to a predetermined position of the inner side surface of said lamp fixing portion via said heat insulating portion; and
a first attachment/detachment structure enabling said lamp fixing portion, to which said gas discharge tube is fixed via said heat insulating portion, to be attached and detached, while said gas discharge tube being fixed thereto, with respect to a remaining portion that is fixed to said base and constitutes the outer shell of said lamp container together with said lamp fixing portion.

Abstract
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.
