Abstract
This disclosure depicts a light source device for an endoscope, incorporating a lamp to supply the light to a light guide fiber bundle for the illumination of the endoscope. This light source device for the endoscope has a heat radiating device for the light guide fiber bundle for the illumination, which has been highly heated by the radiant heat of the lamp. The radiating device includes a support ring and radiator fins radially movably mounted to and supported by the support ring via resilient members. When a light inciding end portion of the light guide fiber bundle for the illumination is installed into the light source device for the endoscope, the heat radiating device is moved radially outwardly against the biasing forces of the resilient members, and the radiator fins are reliably brought into close contact with the outer periphery of the light inciding end portion of the light guide fiber bundle. As the result, the light source device for the endoscope according to the present invention is high in radiation efficiency and can prevent the light guide fiber bundle from being highly heated.
