The utility model relates to an induction discharge fluorescent lamp. The inner side of an ovate discharge bulb is charged with metal vapor and inert gas; the inner wall is coated with a layer of fluorescent substance; the external surface is coated with a layer conducting film which is connected to earth; the bottom end is provided with a concave cavity; the cavity is provided with an induction coil which is wound on one end of a synthetic material sleeve barrel; a soft magnetic material iron core which is sheathed on one end of the heat pipe of a liquid-sucking core corresponding to the induction coil is arranged in the sleeve barrel; the sleeve barrel and the heat pipe of a liquid-sucking core both extend out of the cavity and are fixedly connected with a heat dissipation supporting seat; the output end of a high frequency electron source is connected with the induction coil. The utility model has the advantages of favorable heat dissipation effect on fluorescent lamps, little temperature difference between inside and outside, full utilization of high frequency energy, capability of operation in any state and no electro magnetic interference to the outside.
