    摘要： This invention relates to a fluorescent lamp with an elongated discharge path of annular or flat cross section and with a multiplicity of at least four sequentially energized electrodes at one end of the discharge path in combination with switching means, preferably of the solid state-type for energizing the electrodes. In a preferred embodiment of the invention the lamp has a single base at one end and the auxiliary equipment for operating the lamp is arranged within the lamp base.
