Abstract

PURPOSE:To reduce the fluctuation of the lamp voltage by providing a recess for receiving the metal amalgam remaining in a light emitting tube during the lighting to an electrode conductor while encapsulating the portion following to said recess to the end section of said tube. CONSTITUTION:A recess 6 is provided in an electrode conductor 4 having an electrode 5 at the tip, while in the end cap 2 of a discharge tube 1 the portion following to said recess 6 is encapsulated through a cement 7. Said recess 6 is positioned in the end cap 2 to protect from the discharge space. Consequently the metal amalgam remaining during the lighting of the discharge lamp 1 is held in said recess 6. Consequently the fluctuation of the lamp voltage can be reduced.
