摘要： A cold-cathode fluorescent lamp includes an opposing pair of electrodes in spaced relationship in a tubular glass bulb of which the inner wall surface is coated with fluorescent material, and each of the electrodes is divided into four plate-like electrode members each having mercury and getter preliminarily coated thereon while maintaining a necessary area for each electrode without any contact with the inner wall surface of the tubular glass bulb. The opposite ends of the tubular glass bulb are airtightly sealed with beads through which electricity feeding wires extend for feeding electricity to the electrodes while holding the electrodes in the tubular glass bulb. Two of the four plate-like electrode members are located on one side of each electricity feeding wire, while another two of the same are located on the opposite side of the same. The respective plate-like electrode members are spot-welded to each electricity feeding wire. With this construction, the length of each electrode as measured in the axial direction of the tubular glass bulb can be shortened, and moreover, the length of a non-illuminating part of the cold-cathode fluorescent lamp can also be shortened. Consequently, the whole length of the foregoing type of cold-cathode fluorescent lamp can be shortened. Each of the electricity feeding wires may fully be composed of a Dumet wire.

摘要： There is 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 an 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 is present in the 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.
