    Abstract: Peripherally welding straight contact pins at the base of the electrodes in a cold cathode lamp provides an electrode mount and lamp structure capable of withstanding and remaining functional when subjected to high vibratory and/or shock conditions. While the preferred electrode mount employs straight contact pins welded to the base of the electrode and passed through a cooperating enveloping glass tube, it has been found that an inexpensive electrode mount can be provided by bending commercially available miniature electron tube contact pin assemblies to peripherally surround the electrode and then welding the contact pins to the base of a hollow electrode. Commercially available glass tubes are then sealed to the contact pin assemblies. While any bending of the supporting contact pins is not desired, the inexpensive electrode mount, although not the most preferred form, is still capable of performing under high vibratory and shock conditions.

    Abstract: An emissive electrode of the type utilized in fluorescent lamps and a method for making such an electrode. The electrode includes a fused pellet and a metal lead extending from the bottom surface thereof. The pellet contains a fused mixture of electron emissive material and a metal having a high melting point and a low vapor pressure. The pellet has a bulk density gradient structure wherein the interior portions and exterior bottom and side portions thereof have a high bulk density relative to the bulk density of the exterior top portion of the pellet, and the exterior bottom and side surfaces of the pellet are smooth re1ative to the exterior top surface thereof. The pellet is formed by mixing a powder of said metal with a powder of said electron emissive material, compressing said mixed powder and heating it in a mold until an exothermic reaction occurs.
