Abstract

PURPOSE: To obtain reliable starting by constructing the bymetal with a slow action bymetal and tablet contact.
CONSTITUTION: Upon starting of power supply, the filament 12 is heated to deform the bymetal 16 thus to separate the contacts 17, 19. When closing said bymetal switch 13 high voltage pulse is produced by the inductance in the ballast to start. After starting the heat from the light emitting tube 3 maintains said bymetal switch 13 in open state. Since the bymetal 16 performs slow action, it takes relatively long time after separation of the contacts 17, 19 untill they depart enough not to produce the spark. Since said contacts 17, 19 are tablet type they cause chattering to produce inpulse voltage. Consequencly it starts reliably without causing dielectric breakdown of the ballast.
