Abstract
PURPOSE:To reduce the damage which a cation gives to the filament of an electrode and prolong the life of the electrode by adding magnetic field in the perpendicular direction to the direction of axis of a fluorescent lamp, in the vicinity of the electrode filament. CONSTITUTION:A pair of magnets 11 and 11' which are formed in an arc form and extend in the axial direction are fixed on the stem 3 of a fluorescent lamp A by a supporting metal fitting 12 so as to enclose a filament 5. The inside of the magnet 11 is magnetized to be N pole, and the inside of the magnet 11' is magnetized to be S pole, and magnetic field is applied so as to cross the direction of transfer of ions and electrons in the lamp A. Therefore, the ions emitted undergo a spiral movement, having the line of magnetic force as an axis, when the ions enter the magnetic field, and the number of collision with rare gas increases, and the kinetic energy decreases, so the sputtering action due to ion collision is lightened, and the life of electrode can be improved sharply.
