Abstract
PURPOSE: To prevent irregularly filled mercury amount in a capsule of metal containing mercury attached to an annular fluorescent lamp by filling inert gas from one side of a linear bulb attached with the capsule and heating the bulb while cooling the capsule to thereby prevent the capsule from damaging.
CONSTITUTION: A linear bulb 6' disosed at the electrode mount 5 having an evacuation side fine tube 1, filament 12, or the like at upside and at the electrode mount 5' having opposite evacuation side fine tube 3, metal capsule 8 codntaining mercury inserted into the fine tube 3, filament 12', or the like at downside is inserted into a holder 2. The fine tube 3 is then inserted through the inner passage 7 of a nitrogen gas feeding post 4 to feed the gas into the bult 6 and also inserted into a heating furnace to heat at 600 to 800°C. Then, the bult is formed in annular shape by an annular mold (not shown). The capsule 8 is always cooled by the nitrogen gas to cause no breakage. The bulb 6 is then completed at the later predetermined steps.
