Abstract

PROBLEM TO BE SOLVED: To provide an ultraviolet fluorescent lamp which can emit both the light of UV-A band with high permeability into the inside of ultraviolet curing resin and the light of UV-C band with high curing power of the surface of ultraviolet curing resin. SOLUTION: An airtight container 12 is made of soda lime glass for the use of sterilization lamp which transmits luminescent line of mercury with wavelength of 253.7 nm and a discharge medium containing mercury and rare gas is enclosed in it. A pair of electrodes arranged within the airtight container 12 generate low pressure mercury vapor discharge within the container 12 and the discharge excites a fluorescent material 18 applied on the inner surface of the container 12 with the thickness of 0.3 to 6.0 mg/cm<2> . The fluorescent material 18 emits near-ultraviolet light with the wavelength of 320 to 400 nm, thus ultraviolet lights of both UV-A band and UV-C band are obtained with one lamp.

2. Description of the Related Art For example, a germicidal lamp is used for drying an ultraviolet-curable resin such as an ultraviolet-curable nail polish. The germicidal lamp has a wavelength of 253.
By irradiating ultraviolet rays (mercury emission line) of 7 nm and germicidal rays to the ultraviolet curing resin, the ultraviolet curing resin such as ultraviolet curing nail varnish is dried, that is, cured.

In this case, when the thickness of the UV-curable resin becomes 0.1 mm or more, the inside of the mercury emission line having a wavelength of 253.7 nm becomes hard to be hardened as required due to the UV absorbing action of the resin itself. On the other hand, the wavelength is 320 nm in the UV-A region.
When a near-ultraviolet fluorescent lamp that generates near-ultraviolet light of up to 400 nm is used, the near-ultraviolet light penetrates into the ultraviolet-curable resin because the near-ultraviolet absorption of the ultraviolet-curable resin itself is small. Can be cured. Thus, in recent years, in curing an ultraviolet-curable resin, not only a mercury emission line having a wavelength of 253.7 nm but also near-ultraviolet rays in the UV-A region have been required.
