Abstract

PURPOSE:To prevent the generation of high surge voltage and protect stabilizers etc. from the damage due to dielectric breakdown by allowing the gas which lowers the surge voltage to exist in a fixed pressure in an outer bulb. CONSTITUTION:When a lamp is connected with a power source through a stabilizer, electric current does not flow in a luminous bulb 1, but in a starting circuit 5, electric current flows through a thermoswitch. When the temperature of a bimetal 9 rises-up to a fixed temperature, the thermoswitch opens, and in the choke which constitutes the stabilizer, a high surge voltage is induced, and applied to the luminous bulb 1, and the lamp lights. In the outer bulb 20, the gas which lowers the surge voltage which is generated in case out of operation of the bimetal piece 9, for example at least one kind of xenon, krypton, argon, neon, helium, and nitrogen is filled in 7X10<-3>-2Torr.
