Abstract
An internal induction lamp with a glass envelope bulb assembly and an inductor shaft assembly. The glass envelope bulb assembly is a hollow glass envelope bulb with a mercury amalgam stem protruding downwards from the bottom of the hollow glass envelope bulb. The mercury amalgam stem is fragile, and protected by a stem protector. The inductor shaft assembly, which inserts into the glass envelope bulb assembly accommodates the protrusion of the mercury amalgam stem along with the stem protector. The inductor shaft assembly and envelope bulb assembly may attach via a threaded ring connector. The inductor shaft assembly may have a heat sink, and a gap within the heat sink to accommodate placement of the stem protector within this gap.
