The gist of this is that a core material made of a solid or semi-solid organic transparent material having a refractive index higher than the refractive index of the cladding material is filled inside a cylindrical cladding material with an inner diameter of 2φ or more. Then, both ends of the cylindrical cladding material are sealed with a heat-resistant transparent window material made of glass, quartz, etc., and half of the window material at one end is placed inside a lamp house with a light source installed on one side of the sealed interior. It consists of a spotlight in which the tip of the inserted and enlarged window material is fixed at the focal point of the light from the light source.
