Abstract

To restrain temperature rise at a protruded side part of a light-emitting tube of a light source device, and to prolong the lifetime of the light-emitting tube. A light source device 10 comprises a heat conductive member 20 joining the arc tube 12 installed in a reflector 11 to the reflector 11. The heat conductive member 20 comprises an externally fitting annular part 21for fitting the sealing part 13d of the arc tube 12 thereon, extension parts 23 and 24 extending from the externally fitting annular part 21, and a fitting annular part 22 connected to the extended ends of the extension parts 23 and 24 and fitted to the inner edge of the reflector 11. Heat from the sealing part 13d generated by the lighting of the arc tube 12 is conductive to the reflector 11 through the heat conductive member 20 to prevent the temperature of the sealing part 13d from exceeding the heat resisting temperature thereof.
