Neon lamp production method and system

Abstract

A neon lamp including a sealed glass bulb, electrodes and leads connected to the electrodes has a flat head whose center region descends into the interior of the sealed glass bulb. A method of producing the neon lamp includes steps of charging neon gas into a glass tube through a fine glass tube at the head of the glass tube, sealing the fine glass tube to obtain a sealed glass bulb having a projecting tip portion, removing excess glass of the projecting tip portion, and shaping the projecting tip portion into a substantially flat or lenticular head portion. A system for producing the neon lamp includes a shaping head for accommodating the sealed glass bulb with its projecting tip portion exposed outside the shaping head, heating means for melting the projecting tip portion, a projecting tip cutter for removing excess glass of the projecting tip portion, and a head presser for shaping the projecting tip portion into a substantially flat or lenticular shape.
