Abstract

PURPOSE:To lower the starting voltage under the high pressurized mercury vapor and to shorten the restarting time of a high pressure discharge lamp, by connecting the one end of a filament to one side of a main electrode and then by disposing the shortest distance from the other end of the filament to the other side of the main electrode so as to be the specified distance between arc spots. CONSTITUTION:Two main electrodes 2 and 3 are sealed at the end of a luminous tube 1, on the same side thereof; one end of a filament 5 and the two main electrodes 2 and 3 are connected to a lighting system through molybdenum foils 14- 16 and lead wires 8-10, and the former lighting system includes the luminous tube 1 and a transparent external tube therein. Also, the distance delta from the main electrode 3 to the filament 5 is disposed so as to be with 80% of that between the arc spots, for instance, 3mm.. Thereby, the starting of discharge can be facilitated remarkably, and the restaring time can be also shortened.
