Abstract (en)
In a fluorescent lamp device, a discharge tube (10) is made by arranging electrodes (16, 17) at the ends of a glass tube, sealing mercury and a rare gas into the glass tube and coating the inner surface of the glass tube with a phosphor (22), and an amalgam forming material (24) is disposed close to one or the other of the ends of the discharge tube (10). This fluorescent lamp is operated with a d.c. current using as the anode the electrode (16 or 17) arranged on the discharge tube end side where the amalgam forming material (24) is located.
