摘要:
There are provided a preform for a fluorescent lamp comprising a bulb and a stem provided with a filament and a discharge electrode and a fluorescent lamp prepared by the preform without any exhaust pipe for use as an indicating lamp, the fluorescent lamp being sealed after exhausting inside air and charging inert gas and mercury through an appropriate space formed between the bulb and the stem inserted into the bulb. Thus, even when liquefied mercury liquefied is present in a discharge chamber, it receives a large amount of heat from the filament applied voltage and is easily and quickly evaporated, whereby the characteristics of the lamp become stable quickly after turning on the lamp.

A single terminal type discharge lamp is provided, which comprises: a burner; a socket; a tubular holder, to which the burner is fitted, provided in the socket along a predetermined direction in which the burner is to be aligned; and a tubular metal holder spring which is mounted to the holder for radially depressing the holder toward the burner with deflecting force; wherein the burner is adhered to the socket due to the melt of the holder caused by the heat of the holder spring owing to radio-frequency heating which is performed when the one end of the burner is fitted to the holder such that the burner attains a predetermined position. Accordingly, the number of parts and the number of manufacturing steps are both reduced, thereby reducing costs of the discharge lamp.

A method of manufacturing a vaporized metal discharge lamp includes the steps of attaching a metal halide to the tip of a metal rod through vapor deposition or sputtering; inserting the rod into a light emission envelope of the lamp; and transferring the metal halide attached to the metal rod tip to the inside of the envelope through high frequency induction heating.
