Abstract
A photoirradiation device includes an insertion path for inserting a wire rod; a first reflector having a circular arc shape centered on a point shifted from a center of the insertion path by a first distance, one side of the first reflector facing the insertion path being a reflective surface; a second reflector disposed adjacent open edges of the first reflector and having a circular arc shape centered on a point shifted from the center of the insertion path by a second distance that is different from the first distance, one side of the second reflector facing the insertion path being a reflective surface; and a light source that is positioned on an opposite side of the insertion path from the first reflector and that projects light toward the wire rod.
Claims17
A photoirradiation device comprising:
- an insertion path for inserting a wire rod;
- a first reflector having a circular arc shape centered on a point shifted from a center of the insertion path by a first distance, one side of the first reflector facing the insertion path being a reflective surface;
- a second reflector disposed adjacent open edges of the first reflector and having a circular arc shape centered on a point shifted from the center of the insertion path by a second distance that is different from the first distance, one side of the second reflector facing the insertion path being a reflective surface;
- and
- a light source that is positioned on an opposite side of the insertion path from the first reflector and that projects light toward the wire rod.
A photoirradiation method with which a photoirradiation device projects light toward a wire rod,
- the photoirradiation device including:
- a first reflector having a circular arc shape and an inwardly facing surface as a reflective surface;
- a second reflector disposed adjacent open edges of the first reflector and having a circular arc shape and an inwardly facing surface as a reflective surface;
- and
- a light source that projects light toward the wire rod,
- the photoirradiation method comprising:
- a step of inserting the wire rod into a region inside the reflective surface of the first reflector and inside the reflective surface of the second reflector such that a center position of the wire rod is shifted by a first distance from a center of the reflective surface of the first reflector and shifted by a second distance that is different from the first distance from a center of the reflective surface of the second reflector;
- and
- a step of projecting light toward the wire rod from the light source positioned on an opposite side of the wire rod from the first reflector.
