Abstract

Electrodeless low-pressure discharge lamps (1, 13) are known from the prior art. Such electrodeless lamps are favorable because their discharge vessel (2, 14) filled with mercury vapor and a rare gas has small dimensions compared with commercially available low-pressure discharge lamps provided with electrodes. The invention relates to an improved electrodeless low-pressure discharge lamp, comprising an ionizable substance, comprising molecular halide, in its discharge vessel, and which comprises induction means said electric field in said vessel (2, 14), and thermal insulation means for thermally insulating the discharge vessel 2, 14) at least partially.
