The invention relates to a spiral fluorescent lamp which is provided with a spiral curved glass tube formed by a plurality of short straight tubular glass tubes and short arc glass tubes that are distributed orderly to form a multilateral spiral structure. Compared with the ordinary spiral glass tube, approximately 80 percent of energy consumption can be saved for bending and manufacturing the multilateral spiral glass tube; Mechanization and automatization of a syphon technology for the multilateral spiral glass tube can be realized easily, thus effectively improving the syphon quality and reducing the syphon cost, wherein, an arc syphon part between two adjacent short straight tubes can form an effective 'cool end' when discharging, thereby improving the illumination efficiency. The multilateral spiral fluorescent lamp can be made into energy-saving lighting sources of various specifications.
