Abstract
A discharge lamp (1) with a base (2), suitable for operation by means of a dielectrically impeded discharge, has a spacing between the base (2) and the outer wall of the discharge vessel (3). The overall efficiency of the generation of UV radiation is improved thereby.
Claims21
A discharge lamp comprising:
- a base, a discharge vessel enclosing an ionizable filling, an inner electrode arranged inside the discharge vessel, and outer electrodes fitted on the outer wall of the discharge vessel;
- the discharge vessel having a stem through which the inner electrode is connected in a gas-tight fashion to a first outer supply lead, the stem being fastened to the base;
- the outer electrodes being connected to supply leads, the spacing between the supply leads of the outer electrodes and the inner electrode being not less than the spacing between the outer electrodes and the inner electrode, the supply leads of the outer electrodes being connected to an electric conductor, the electric conductor surrounding the stem and being connected to a second outer supply lead.
A discharge lamp comprising:
- a base, a circular cylindrical discharge vessel enclosing an ionizable filling, an elongated spiraled inner electrode centrally arranged inside the discharge vessel, and outer electrodes fitted on the outer wall of the discharge vessel, the outer electrodes being equidistant and parallel to the longitudinal axis of the inner electrode;
- the discharge vessel having a stem through which the inner electrode is connected in a gas-tight fashion to a first outer supply lead, the stem being fastened to the base;
- the outer electrodes being connected to supply leads, the spacing between the supply leads of the outer electrodes and the inner electrode being not less than the spacing between the outer electrodes and the inner electrode, the supply leads of the outer electrodes being connected to an electric conductor, the electric conductor surrounding the stem and being connected to a second outer supply lead.
