Abstract: An illuminator includes: a first cylindrical member with a mirror-like inner surface formed to facilitate light reflection; a flat plate member having an aperture in its center; LEDs with trimmed distal ends and arranged in a circle along the periphery of the aperture; LEDs with trimmed distal ends and arranged in a circle along a circumferential direction of the first cylindrical member so as to be located on a lengthwise middle part of the inner surface of the cylindrical member; a second cylindrical member having an engagement portion engaged with the cylindrical member, LEDs with trimmed distal ends and arranged in a circle along a circumferential direction of the engagement portion; and a ring-shaped semitransparent diffusion plate. The illuminators illuminate a to-be-mounted component with light having a directivity.
