Abstract

PURPOSE: To make the promotion of prolongation of service life for the stabilizer filament, with a defective lighting compensated, by connecting a series circuit, consisting of auxiliary light source filament, a closing switch for a luminous tube not lighting and a closing switch for a temperature exceeding the level of lighting capable, in parallel to the luminous tube.
CONSTITUTION: Across power source terminals a, b, are connected in series a stabilizer filament 7, an energizing coil 9 and main electrodes 3,4 of a lumionus tube 2, as well connected a series circuit, consisting of a relay switch S18, an auxiliary light source filament 10 and a bimetal switch S211, in parallel to the luminous tube 2 for the power source. In this way, simultaneously with the luminous tube 2 going out, the auxiliary light source filament 10 starts lighting with a defective lighting made compensatable together with a lighting of the stabilizer filament 7, and simultaneously with the luminous tube becoming restartable, a starting begins, without providing a shortening of service life and a flux lowering at the time of steady lighting, thus a defective lighting from the luminous tube can be compensated.
