Abstract

PURPOSE:To reduce the shielding of light from a light emitting tube and to reduce the characteristic variation during the service life, by constructing such that the plane including the filament will perpendicularly cross with the axis of the light emitting tube. CONSTITUTION:A light emitting tube 4 is supported in an outer tube 1 by means of supporting wires 2, 3. A filament 6 for heating a bimetal switch 5 to open is wound in plane configuration utilizing a supporting board 7, then connected in series to the bimetal switch 5 such that the filament face will cross perpendicularly with the axis of the light emitting tube between the supporting wires 2 and 3, and electrically connected in parallel to the light emitting tube 4.
