A UV radiator has an essentially tubular discharge vessel designed to produce dielectric barrier discharges at one end and sealed in a gas-tight manner at both ends, and in each case at least one elongate inner and outer electrode which is oriented parallel to the longitudinal axis of the discharge vessel. If it is imagined that the tubular part of the discharge vessel is split into two equal halves by an imaginary longitudinal section, the at least one inner electrode is arranged on the inside of the first imaginary tube half, and the at least one outer electrode is arranged on the outside of the second imaginary tube half, and essentially diametrically with respect to one another. As a result, and as a result of the shape and number and arrangement of the outer electrode(s), directional radiation characteristics are achieved.
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.
A UV radiator having an essentially tubular discharge vessel, which is designed to produce a dielectric baffler discharge and is sealed in a gas-tight manner at both ends, and having an elongate inner electrode and two or more elongate outer electrodes, 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 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 outer electrodes are 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, the inner electrode being situated at a maximum clearance with respect to the imaginary sectional plane and the outer electrodes being positioned symmetrically such that they have the same clearance from the imaginary sectional plane.
