Abstract
PURPOSE: To prevent the spark between the portions other than the contact thus to prevent the carbonizing of outer tube reliably by making the shortest distance between the bymetal and the contact member in a bymetal longer than specific one.
CONSTITUTION: Upon power supply, the filament 12 produces heat to deform the bymetal 16 thus to separate the contacts 17, 19. When opening the bymetal switch 13, high voltage pulse is produced by the inductance of ballast to start the lamp. Min. gap between the bymetal 16 and the contact member 18 is set longer than 2.0mm. Consequently when the bymetal switch 13 is opened and high voltage is produced, it causes no spark between the bymetal 16 and the contact member 18 thus prevents the carbonizing of outer tube.
