Abstract
PURPOSE: To reduce the restart time by arranging the filament and bimetal switch in this order from the luminous tube to the wall of outer bulb to speed up the closing of bimetal after lighting out.
CONSTITUTION: The filament 22 contained in the outer bulb to apply a high voltage pulse to the luminous tube 12 when starting and the bimetal switch 23 heated by the filament are arranged in the direction perpendicular to the bulb axis in the order of filament and bimetal switch from the luminous tube side, these are opposite to each other. while the lamp is lighted, radiant heat of the luminous tube is propagated to the bimetal switch through gaps of the filament to prevent the closing of bimetal switch. When the lamp is put out, temperature of the bimetal switch is quickly dropped since the filament cuts off remaining heat of the luminous tube, the bimetal switch is rapidly recovered.
