Abstract

PURPOSE:To effectually prevent defective charging of mercury which might be caused by adhesion of mercury to an exhaust tube by heating and evaporating mercury adhering to the exhaust tube. CONSTITUTION:When mercury is charged into a lamp 1 by using a curved tubular exhaust device the lamp 1, a conductor 2 and an exhaust tube 3 are positioned as shown in the figure. It occurs occasionally that immediately after mercury charging is performed mercury 5 adheres on the inner surface of the exhaust tube 3 and does not enter the lamp 1. Therefore, in the next process, the top portion of the exhaust tube 3 is heated by a burner 4 to close the upper end of an exhaust path 8 before the whole of the exhaust path 8 is closed by burners 6. As the result, the mercury 5 heated and evaporated by the burners 6 is introduced only into the lamp 1. After these processes, the exhaust tube 3 and the lamp 1 are chipped off by a burner 7.

Description

【発明の詳細な説明】 〔発明の利用分野〕 本発明は、管内に水銀を封入する方法に係り、特に水銀
無不良の発生防止に好適な、水銀封入方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method of enclosing mercury in a tube, and particularly to a method of enclosing mercury suitable for preventing the occurrence of mercury-free defects.

〔発明の背景〕[Background of the invention]

法が示されている。しかしこの従来技術においては液体
水銀がランプ内へ封入される途中、排気管へ水銀が付着
してしまいランプ内へ所要量の水銀が封入されないとい
う不都合を生ずることがある。JP-A-54-16873 discloses a method for sealing liquid mercury into a lamp. However, in this prior art, mercury adheres to the exhaust pipe during the filling of liquid mercury into the lamp, resulting in a problem that the required amount of mercury is not filled into the lamp.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、けい光ランプ等の管内へ完全に水銀を
封入することを可能にする水銀封入方法を提供すること
にある。An object of the present invention is to provide a mercury filling method that makes it possible to completely fill mercury into a tube of a fluorescent lamp or the like.

〔発明の概要〕[Summary of the invention]

本発明番：１環形けい光ランプ等の中へ水銀を封入する
際、ｔＪｌ＝気管へ付着してしまった水銀を気化させて
管内へ封入することを特徴とするものである。The present invention is characterized in that when mercury is sealed in a one-ring fluorescent lamp or the like, the mercury adhering to the trachea is vaporized and sealed into the tube.

これにより排気管での水銀付着による水銀無不良を効果
的に防止することができる。This effectively prevents mercury-free defects due to mercury adhesion in the exhaust pipe.

Cover the top end, and in the next step, install burner 6 as shown in Figure 2.
This blocks the entire exhaust passage 8. As a result, the mercury 5 heated and vaporized by the burner 6 is guided only into the lamp. After these steps, the third
As shown in the figure, tip-off between the exhaust pipe 3 and the lamp 1 is performed by the burner 7. Here, exhaust pipe 3 and lamp 1
Since the pressure inside is considerably lower than the outside pressure, the exhaust pipe 3 is bent by the burners 4 and 6, and the exhaust passage 8 is completely closed by adjusting the burners 4 and 6.
