Claims

[Claims for Utility Model Registration] (1) A holder in which an observation hole is formed, and a device held on the outer periphery of the observation hole in this holder, in which irradiation ends are arranged all around the outer periphery and the irradiation and a group of optical fibers whose ends are oriented to emit light toward substantially the same location on the extension line of the hole axis of the observation hole. (2) The holder includes a substrate having a conical hole with a tapered end, and a cylindrical body forming the observation hole and having an outer peripheral surface of the tip with a tapered conical surface having the same taper angle as the conical hole of the substrate. , the optical fiber group is
sandwiched between the conical hole of the substrate and the conical surface of the cylindrical body.
The inspection lighting equipment as set forth in claim (1) of the utility model registration, which is bonded. (3) The inspection lighting device according to claim 1, wherein the illumination ends of the group of optical fibers are closely arranged around the entire circumference of the observation hole.
