ことを特徴とする光源装置。 In a light source device in which a light emitting part of a light source lamp is positioned on the focal point of a parabolic mirror reflector, light from the light source lamp is reflected by the reflector and parallel light parallel to the optical axis of the reflector is emitted. A curved reflective surface is provided in front with the light emitting part of the light source lamp as a focal point, and the outer peripheral part of the light emitted radially from the light source lamp directly to the outside of the reflector is directed toward the outer peripheral part of the reflective surface of the reflector. A light source device comprising a ring-shaped auxiliary reflector for reflecting light.
