Abstract
A light source device includes a discharge tube, a reflector for reflecting a light radiated from the discharge tube, and support members for supporting the discharge tube to the reflector. The support member or the discharge tube is formed of a heat insulating structure so as to prevent a temperature drop of a portion of the discharge tube near electrodes thereof. By this arrangement, it is possible to prolong the operational life of the discharge tube.
