Abstract
PURPOSE: To prevent the glow discharge tube from fracture due to heat and current, by connecting series connected glow discharge tube and current limiting element in parallel with the light emitting tube while locating the glow discharging tube below the light emitting tube.
CONSTITUTION: The light emitting tube 1 is filled with metal halide, mercury and rear gas while comprising heat responsive switch 2 having a bimetal to be opened by the heat from the light emitting tube 1, a glow discharging tube 3 and tungsten filament or resistor for limiting the current flowing through said discharging tube 3 and connected in series with the current limiting element 4 wound around the ceramic substrate 5 (said series member is forming aux. starter) and connected across main electrodes of light emitting tube 1. The discharging tube 3 is located below the light emitting tube 1 while the light emitting tube 1 and aux. starter are provided in outer tube 6 filled with inert gas. Consequently the discharging tube can be protected from fracture due to heat and current.
