Radio frequency - shielding assembly for an electrode-less plasma - lighting device as well as an electrodeless plasma - lighting device and method for production thereof

摘要

The invention relates to a radio frequency - shielding assembly for an electrode-less plasma - lighting device, the lighting means body (16) by means of a radio frequency radiation is excited to light up, with a screening cage (2) made of an electrically conductive material, the one grid section (20, 21) having the lighting means body (16), and with a holding means (50, 6) for holding of the screening cage (2) on a housing section (11) of the plasma - lighting device.According to the invention, a circumferentially extending recess (54) is provided, in which a sealing element (9) for the tight against the radio frequency radiation is received, in order to the screening cage (2) against the escape of the radio frequency - radiation to form a tight.It also discloses a process for producing such a radio frequency - shielding assembly.
