Abstract
PURPOSE: To make the compensation operable for defective lighting as a gas discharge lamp, by connecting a series circuit, consisting of a switch closing when not lighting a luminous tube and a switch closing when exceeding a lightable temperature, in parallel to the luminous tube and in series to a stabilizer filament.
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 luminous tube 2, as well as connected a series circuit, consisting of a relay switch S18 and a bimetal switch S210, in parallel to the luminous tube 2 for the power source. In this way, simultaneously with the luminous tube 2 going out, the switch S1 is closed to construct a closed circuit, constituted by the stabilizer filament 7 and switches S1, S2, for the power source, with the stabilizer filament kept lighting, thus a defective lighting can be compensated by utilizing the stabilizer filament in a simple method of connecting the switches S1, S2.
