The utility model belongs to the technical field of high-frequency electrodeless discharge lamps and discloses a high-power high-frequency electromagnetic discharge lamp which is mainly technically characterized in that the electromagnetic discharge lamp comprises a lamp shell with a cavity at the middle part, and a shell seat adhibited at the mouth of the cavity; a rod body provided with a coupler seat at the bottom is arranged in the cavity and a coupler is fixed on the coupler seat; the coupler seat and the shell seat are adhibited into a whole structure; and one, two, three or a plurality of heat dissipation holes are axially arranged at the central part of the rod body. When the high-frequency electromagnetic discharge lamp is in work, the heat generated by the coupler can be dissipated through the heat dissipation holes, thereby improving the work efficiency of the coupler. Meanwhile design power of the electromagnetic discharge lamp is improved.
