Abstract

PURPOSE:To shorten the restarting time by applying a voltage between the electrodes, while heating a filament which extends from the tip of electrode toward the end of a light emission tube. CONSTITUTION:A main electrode core is wound around at least one electrode 2 of electrodes 2, 3 provided on both ends of a light emission tube 1, then a filament 5 is extended from the tip of said electrode toward the end of the light emission tube 1. When restarting is tried under the mercury vapor pressure of higher than 100 Torr, the required voltage is applied between the electrodes 2, 3, while heating the filament 5 with electric current in order to start a discharge.
