LAMP HOLDER FOR A DIELECTRIC BARRIER DISCHARGE LAMP

摘要

A lamp holder for a dielectric barrier discharge (DBD) lamp (1), especially for use in a treatment system or reactor or housing or in an irradiation apparatus, for radiating a medium like a fluid and/or a gas and/or a solid material by means of the DBD lamp (1) is disclosed. The holder substantially comprises two end caps (21, 31) at the axial ends of the lamp (1) and an inner electrode (23, 24; 33, 34) with a screw fitting (SF) for exerting an axial pressure on both axial ends of the lamp (I) via both end caps (21, 31) and with axial bores (25, 35) into an inner volume (14) for guiding especially a cooling medium and for electrically contacting an inner tube (II) of the lamp (1). The holder has a comparatively simple construction and can easily be assembled. Furthermore, even larger tolerances of the lamp length can be compensated and a reliable sealing of the inner volume (14) against the outside of the lamp (1) is achieved.
