Abstract

The electrodeless low-pressure discharge lamp has a lamp vessel (1) having a cavity (2) at an end portion (3) thereof. An electric coil (4) surrounding a plastic sleeve (5), wherein a liquid-filled tubular container (7) surrounded by a soft-magnetic core (6) is present, is accommodated in the cavity (2). The plastic sleeve (5) is substantially filled up with an elastic polymer. Additionally, the tube (5) may be enveloped by an elastic polymer (9). The elastic polymer ensures a relatively low operating temperature of the members inside the cavity (4).
