    摘要： The cathode for a gas discharged lamp includes gettering materials which are placed within the interior of the cathode shell. Other components may also be placed inside the cathode for continuous activation. For example, in mercury vapor lamps, a mercury amalgam is placed within the cathode. In another embodiment, a mass of electron emission assisting compound is placed within the cathode to replenish the emission assisting compound which deteriorates from the cathode.

    摘要： An indirectly heated cathode incorporated in a gas discharge tube with a discharge current of 0.2 to 0.4 A has a cathode surface area in a range of 10 to 30 mm.sup.2. A cathode cylinder is made of molybdenum, nickel or alloy thereof. A heater coated with alumina for insulation is inserted into the cylinder in such a manner that the distance between the heater and cylinder is 0.1 mm or less, and coil gaps of the heater are set to 0.15 mm or less. Alternatively, the space between the heater and cylinder is filled with alumina. As a result, the ratio of a heat quantity by forced heating to a heat quantity for starting discharge is made 0.3 or less.

    摘要： A hollow cathode electrode, particularly useful in fluorescent lamps, comprises an outer metal sleeve, an inner metal sleeve disposed within the outer sleeve and an emissive mix disposed on the inner sleeve. In one embodiment, the inner sleeve is a folded cylinder having a square cross section disposed within a circular cylinder. The object of the present invention is to prevent heat loss from the inner sleeve and to minimize sputtering. The electrode of the present invention may also include a third exterior sleeve surrounding but not contacting the interior sleeve or sleeves.
