ABSTRACT:
A cathode is arranged at one end of an envelope of a fluorescent lamp, and a plurality of anodes are arranged at the other end. A discharge path-forming structure is disposed between the cathode and anodes. The structure comprises a vessel having an open end at the position adjacent to the anodes and an inner space, and also comprises a dividing element for dividing the inner space into a plurality of divided discharge paths each including a corresponding anode. A fluorescent material layer is coated on the inner surface of the vessel in a manner whereby the lamp generates different color light beams.
