Patent ID: 7411349

Claim:
A UV radiator having an essentially tubular discharge vessel, which is designed to produce a dielectric barrier discharge and is sealed in a gas-tight manner at both ends, and having at least one elongate inner electrode and at least one elongate outer electrode, the inner and outer electrodes being oriented parallel to the longitudinal axis of the discharge vessel and extending the length of the tubular discharge vessel, whereby the at least one inner electrode is arranged on the inside of an imaginary first tube half of the tubular part of the discharge vessel in a holder that is fixed to the inside of the first imaginary half of the discharge vessel, the at least one inner electrode being threaded through the holder and the holder holding the at least one inner electrode so that the at least one inner electrode does not sag to a significant extent, and the at least one outer electrode is arranged on the outside of an imaginary second tube half, which is opposite said first tube half, the two opposing tube halves being defined by an imaginary sectional plane, which contains the longitudinal axis of the tubular discharge vessel.
