ABSTRACT:
The electrodeless low-pressure discharge lamp comprises a tube which is closed at one end, which surrounds a body of soft magnetic material with clearance, and which is enclosed with clearance in the cavity in the outer bulb, which cavity enters the cavity in the discharge vessel. The tube provides a good insulation of the body from the heat of the discharge in the discharge vessel.
