UV fluorescent tube for use in solariums or similar has a light intensity wavelength characteristic such that erythema inducing radiation is largely absent, while other wavelengths are maximized

摘要

UV fluorescent tube for use in solariums or similar has a low pressure tube with a base fluorescent substance composition whose erythema inducing light intensity at a wavelength of less than 320 nm is less than or equal to 0.15 W m-2. The fluorescent substance composition above this wavelength is such that there is a much higher light intensity or yield above this wavelength.
