Abstract :
This paper deals with the induction lamp, or more generally speaking, the electrodeless electrical discharge. This lamp is a rich source of visible and ultra-violet radiation. The lamp has no electrodes, no conducting filaments and no conducting arc, as ordinarily understood. It operates on the principle of the electrodeless discharge which is produced in a partly exhausted vessel within a rapidly changing electromagnetic field. The discharge consists of visible and invisible radiations. The paper contains a historical introduction, an explanation of the theory of the electrodeless discharge and a description of the results of experiments.
