  • Patent number: 8399869
    Abstract: In various embodiments, a UV luminaire may include a housing which is designed for accommodating a plurality of UV lamps and a protective atmosphere, wherein the housing is subdivided in such a manner into chambers respectively containing some of the UV lamps and can be opened in such a manner that each of the UV lamps can be replaced with detriment to the protective atmosphere only of the respective chamber.
    Type: Grant

  • Patent number: 7411349
    Abstract: 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.

  • Patent number: 7224111
    Abstract: An elongated dielectric barrier discharge lamp with outer and inner electrodes has a tube that is arranged on the lamp stand end of the discharge vessel and that surrounds the lamp stand. The tube serves to receive a seal in order to install the lamp in a process chamber in a gastight manner. Power supply of the outer electrodes is separated from the power supply for the inner electrodes coming out of the lamp stand by means of the above-mentioned tube. This makes it possible to prevent effectively parasitic discharges between the power supplies which are applied at different potentials during operation also in process chambers under negative pressure.

  • Patent number: 6847157
    Abstract: A dielectric barrier discharge lamp having a cap (2), an elongate discharge vessel (1) and strip-like outer electrodes (5a-5f) has a corresponding contact spring (7a-7f) for each outer electrode. These contact springs are arranged in the interior of the cap. The cap also includes a cap sleeve (6), which surrounds one end of the discharge vessel (1) in such a manner that the or each strip-like outer electrode (5a-5f) is in electrically conductive contact with the or a corresponding contact spring (7a-7f). Preferably, the transverse extent of the individual contact springs, at least in the region of the contact, is less than or equal to the width of the corresponding strip-like outer electrode. This design combines ease of installation of the cap with a reliable contact and a high lamp efficiency.

  • Patent number: 6686681
    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.

  • Patent number: 6634917
    Abstract: The invention relates to a method for producing a discharge lamp, which is preferably designed for dielectric barrier discharges. The innovation is that a frame is used in order to set, and secure in its position, an electrode running at a distance from the vessel faces in the discharge vessel of the discharge lamp. This frame is simultaneously used as an exhaust tube.
