変向体を設けた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 ring-shaped light deflector is provided in front of the reflector to reflect or refract the light reflected at the outer peripheral edge of the reflector toward the optical axis of the reflector, and a ring-shaped light deflector is provided in front of the light source lamp and located on the optical axis of the reflector. and a small-diameter central light deflector that refracts or reflects the light from the ring-shaped light deflector forward into parallel light parallel to the optical axis of the reflector. Device.
