Abstract

PURPOSE:To reduce the scattering of surge voltage and prevent the breakage of a current limiting resistor by sealing mercury or a gas with specific pressure in an outer tube and providing a thermal response switch and the current limiting resistor with a specific distance between the contact point of the switch and the resistor. CONSTITUTION:A starting circuit to which a current limiting resistor 6 comprising a thermal response switch 9 and metal wire coil for heating is connected in series and a light emission tube 1 are contained in an outer tube 20, and mercury or a gas with a pressure of 10<-4> to 10 Torr is sealed in the outer tube 20. The thermal response switch 9 and current limiting resistor 6 are provided so that the distance between contact points 10, 11 of the switch 9 and the resistor 6 is 12mm. or more. Thus the scattering of surge voltage is reduced through the sealing of the gas and the dielectric breakdown of a stabilizer 28 during off-lighting of the luminous tube 1 is prevented, and the discharge between the contact points 10, 11 and the current limiting resistor 6 is reduced to prevent the breakage of the current limiting resistor 6 and to improve the life.
