PURPOSE:To improve the condensation efficiency of illumination lights by arranging this illuminator so that it may illuminate the illumination light from a light source efficiently to a face to be illuminated. CONSTITUTION:The illumination lights from the light source 11 arranged on one focus C of an ellipsoidal reflector 9 are condensed with the ellipsoidal reflector 9, and the direction of illumination one part of the reflection from the ellipsoidal reflector 9 is turned, with the outside of the spherical surface of the ellipsoidal reflector 10 as a reflection face. And, lights are condensed at another focus D, passing through the aperture 101 being made at the spherical reflector 10 inclusive of the intersecting point between the optical axis O of the ellipsoidal reflector 9 and the spherical reflector 10. |
