Abstract
A dielectric-barrier discharge lamp device that can reliably prevent leakage of the coolant fluid used to cool the dielectric-barrier discharge lamp, and that can reliably cool the dielectric-barrier discharge lamp, is achieved by the dielectric-barrier discharge lamp device having a dielectric-barrier discharge lamp ( ) with a hollow-cylinder-shaped discharge space (P) formed by an outer tube ( ) that is roughly cylindrical in external shape and a co-axial inner tube ( ), in which the inner tube ( ) has a cylindrical tube extension ( A) that extends outward from the discharge space ( ), and in which the outer periphery of the end ( A ) of the tube extension ( A) is held tightly by a coupler fitting ( ) connected to a guide tube ( ) through which a coolant fluid flows.
