Abstract
A light intensity adjustable ultraviolet device for curing an optical fiber coating includes a cylindrical mounting base; a UVLED light source module mounted along a peripheral direction and an axial direction in an inner cavity of the cylindrical mounting base; a cylindrical focusing lens configured in front of a light emitting surface of the UVLED light source module, so that ultraviolet light emitted by the UVLED light source module is focused on a curing axis; and an ultraviolet sensor mounted in the inner cavity of the cylindrical mounting base, wherein the ultraviolet sensor is connected to a UVLED power supply control module via an ultraviolet intensity signal processing module; the UVLED power supply control module is connected to the UVLED light source module, so that an optical fiber drawing speed and an ultraviolet intensity form a control closed loop.
