ABSTRACT:
A lamp electrode adapted to deliver mercury during an assembly process has a supporting electrical lead attached to the proximal end of a metallic shell. The proximal and a distal ends of the metallic shell each lie along a central axis. A container with a vitreous plug in a sealed end contains a substance for delivering mercury upon heating of the container. The sidewall of the container is attached to the electrical lead. The longitudinal axis of the container is skewed relative to the electrical lead to orient the container in a direction to reduce discharge of mercury directly toward the metallic shell. The container is heated to open it and discharge a mercury dose from the sealed, end, which is prone to opening upon heating of the container.
