Abstract:
1. A lamp electrode adapted to deliver mercury during an assembly process, comprising: an electrode subassembly including: (a) a metallic shell having a proximal end and a distal end each lying along a central axis, (b) a supporting electrical lead attached to the proximal end of said metallic shell, and (c) a vitreous tube fused onto said electrical lead to surround said shell; and a container having a sidewall, a sealed end, and a longitudinal axis, said container containing a substance for delivering mercury upon heating of said container, said container being attached to said electrode subassembly and spaced proximally from said metallic shell, the longitudinal axis of the container being skewed to avoid parallelism relative to said central axis in order to orient said container in a direction to reduce discharge of mercury directly toward said metallic shell.
