Abstract: A light source device includes: an excitation light source that emits primary light; a first lens that condenses the primary light; a wavelength converting member that emits secondary light including the primary light and wavelength converted light; a sensor that detects an anomaly in the wavelength converting member; and a second lens that causes light which travels back toward the excitation light source to be incident on the sensor. The sensor detects the light via the second lens. The first lens includes (i) a first face through which the primary light enters, and (ii) a second face opposite the first face from which the primary light that has entered from the first face and transmitted through an inside of the first lens exits. The third face of the second lens has a curvature different from a curvature of the first face and the second face of the first lens.

Abstract: An endoscope lighting device to be used for an endoscope is provided. The endoscope lighting device includes a housing. A laser light source is in the housing. A fiber cable receives laser light emitted by the laser light source. A phosphor of a fluorescent light emitter emits fluorescent light using the laser light exiting from the fiber cable. A blower generates airflow in the housing. A shakable body contacts the fiber cable and shakes in reaction to the airflow generated by the blower.
