Rare-gas low-pressure discharge lamp, method of manufacturing a rare-gas low-pressure discharge lamp, and application of a gas discharge lamp

摘要

A rare-gas low-pressure discharge lamp for generating ultraviolet light, in particular for cosmetic or therapeutic purposes, has a discharge vessel which is filled with rare gas and is at least partly transparent to UV light and which is at least partly coated with a phosphor which radiates UV light upon excitation by an excitation radiation produced in the discharge vessel so as to utilize a desired spectral range.
