Abstract

PURPOSE:To facilitate the starting by extending a filament from the tip side of electrode toward the end section of a light emission tube then applying voltage between the electrodes while heating the filament. CONSTITUTION:When restarting under mercury vapor pressure of higher than 100 Torr, the tip section of an electrode core of at least one electrode 2 of electrodes 2, 3 provided at both ends of a light emission tube 1 is bent by 10-60 deg., then a filament 5 is wound around said bent core and said filament 5 is extended from the tip side of electrode toward the end section of the light emission tube 1, thereafter voltage is applied between the electrodes 2, 3 while heating said filament with electric current.
