。[Scope of claims for utility model registration] (1) A light source section, an optical fiber that transmits light,
It is equipped with an irradiation section that irradiates light guided by an optical fiber to the outside, and this irradiation section consists of an inner tube with an inner lens and an outer tube with an outer lens. The outer cylinder is fitted, and as the outer cylinder slides relative to the inner cylinder in the axial direction, the distance between the inner lens and the outer lens changes, thereby changing the irradiation range. What is claimed is: 1. An optical fiber lighting device characterized in that an elastic ring is provided for sealing the outer surface of the inner tube and the inner surface of the outer tube. (2) The optical fiber lighting device according to claim 1, wherein the elastic ring is an O-ring. (3) The distance between the inner lens and the outer lens is determined by fitting the tip of the screw screwed into the screw hole provided in the outer cylinder into the spiral groove formed on the outer surface of the inner cylinder.
An optical fiber lighting device according to claim 1 or 2, which is capable of fine adjustment.
