A light source device (10) has: a heat-amount-adjusting element (33, 43) thermally connected and adjacent to at least one light source, said element adjusting the amount of heat emitted by a light source according to the emitted heat; and a plurality of light source heat generation units (20, 30, 40) that either include only a light source (21) or include a light source (31, 41) and a heat-amount-adjusting element (33, 43). The light source device (10) has a light source control unit (100) for controlling the light sources (21, 31, 41) and heat-amount-adjusting elements (33, 43) such that the ratio of heat generation amounts of each of the light source heat generation units (20, 30, 40) remains constant and the state of illumination light reaches a desired state. |
