Abstract:
1. A light source device comprising: a light source including a plurality of light emitting elements arranged on a substrate; a temperature detecting section for detecting a temperature of the light source; a temperature adjusting element for adjusting the temperature of the light source by effecting at least one of heat absorption and heat radiation; a heat radiating fin for radiating heat of at least one of the light source and the temperature adjusting element, the heat radiating fin being disposed in direct contact with a housing body of the device; an urging section for integrally forming the light source, the temperature adjusting element, and the heat radiation fin by urging force thereof; and a control section for controlling the temperature adjusting element so that a temperature detected by the temperature detecting section becomes a predetermined temperature which is set to be higher than an environmental temperature at a position in which the light source device is disposed.
