Abstract

PURPOSE: To promote a temperature rise of tube end part and expedite a rise of vapor pressure with a luminous efficiency improved, by using the starting auxiliary coil as a heater for during the time of discharge.
CONSTITUTION: A lighting of the lamp can be maintained by simultaneously performing the operation of discharge liminescence of a luminous tube 11 and of heat generating light emission of a filament stabilizer 12. At this time, a bimetal switch 13 is kept in an opening state by being applied a heat from the luminous tube 11 and the filament stabilizer 12. In a state of discharge lighting, an electric conduction is also being sustained to a starting auxiliary coil 16a, 16b. Accordingly, this coil 16a, 16b is also generating a heat at the end portion of a valve 14. In this way, a temperature of the end portion, that becomes the coldest part in the valve 14 during the time of lighting, is raised, causing a vapor pressure of luminous metal, for instance, mercury to be maintainable at a required value, and a luminous efficiency can be obtained as expected.
