An optical fiber resin coating apparatus having an ultraviolet flash lamp used for coating an optical fiber by an ultraviolet curing resin, a lamp lighting circuit for making the ultraviolet flash lamp emit light, and a control circuit for controlling this lamp lighting circuit. The control circuit detects the intensity and emission time of ultraviolet light emitted from the ultraviolet flash lamp by an ultraviolet sensor and supplies a voltage and excitation time to the power source for exciting the ultraviolet flash lamp based on this. As the ultraviolet light source, at least one ultraviolet laser diode or ultraviolet light emitting diode may be used instead of an ultraviolet flash lamp. The ultraviolet light source may be arranged to emit ultraviolet light so that the coating portion of the ultraviolet curing resin exhibits an inclined profile where the intensity of the ultraviolet light gradually changes according to the position. |
