Abstract: Noble gas low pressure discharge lamp (10) has a UV light-permeable discharge body (12) partially filled with noble gas and partially coated with a phosphor (14) which releases radiation when excited with light produced in the discharge body. An Independent claim is also included for a process for the production of a noble gas low pressure discharge lamp comprising partially coating a discharge body with a phosphor which releases radiation when excited with light produced in the discharge body. Preferred Features: The discharge body is filled with xenon or neon and is made from a glass having a permeability of 20-70 % for light of the wavelength 312.6 nm. The phosphor contains BaSi2O5: Pb, CeMgAl11O19, LaPO4: Ce, SrB4O7: Eu or MgSi2O7: Pb.
