| 摘要 |
The invention relates to a radiofrequency (rf) screening assembly for an electrodeless plasma lighting device having a illuminant member (16) which is excited for illumination by means of a radiofrequency (rf), said assembly comprising a screening (shielding) cage (2), which is made of an electrically conductive material or at least has a surface of an electrically conductive material and has a mesh portion (20, 21) for accommodating the illuminant member (16) therein, and a holding means (50, 6) for holding the screening cage (2) at a housing portion (11) of said plasma lighting device. According to the invention a circumferential recess (54) is provided for accommodating an rf-sealing member (9) for sealing against the radiofrequency in order to seal the screening cage (2) against the leaking of the radiofrequency radiation. Furthermore a method for producing such a radiofrequency (rf) screening assembly is disclosed.
