Method for producing a discharge lamp and discharge lamp

摘要

A method for producing a discharge lamp of the present invention includes the steps of: preparing a glass pipe (50) for a discharge lamp having a luminous bulb portion (10) and a side tube portion (22), and a single electrode assembly (40) including an electrode structure portion (42) that will be formed into a pair of electrodes of the discharge lamp; inserting the single electrode assembly (40) into the glass pipe (50) for a discharge lamp such that the electrode structure portion (42) of the single electrode assembly (40) is positioned in the luminous bulb portion (10) of the glass pipe (50) for a discharge lamp; forming a luminous bulb in which the electrode structure portion (42) is arranged inside by attaching the side tube portion (22) of the glass pipe (50) for a discharge lamp to a part of the single electrode assembly (40); and forming a pair of electrodes (12,12') in the luminous bulb by melting and cutting a part (18) of the electrode structure portion (42) selectively. <IMAGE>
