Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric discharge lamp which effectively generates ozone and excited oxygen, and makes them act on an object.SOLUTION: In an electric discharge lamp 10 comprising an arc tube 11 with double tube structure, a fluorescent substance C that receives ultraviolet light with a 172 nm-wavelength to emit fluorescence with a 250 nm-wavelength is applied to surfaces (external surface 50S of an inner tube 50 and an inner surface 20I of an external tube 20) of the arc tube 11 thinly with an almost uniform thickness over a whole surface. As a result, both ultraviolet light with a 172 nm-wavelength and ultraviolet light with a 250 nm-wavelength are radiated to an outside of the lamp from the whole external surface 20S of the external tube 20 being a radiation surface pf the arc tube 11.SELECTED DRAWING: Figure 1
