Abstract
A light-emitting capsule for use in a reflector-type electric lamp utilized in such applications as display and track lighting. The capsule includes a hollow bulb portion containing a light source (coiled filament or arc) therein and an elongated sealed end including a flattened, narrow width segment and a protruding end segment. The end segment, preferably of similar configuration (cylindrical) as the bulb, is adapted for engaging the internal walls of the reflector's central opening to facilitate capsule positioning within such a reflector in both a precise and stable fashion. Additionally, the bulb portion is also capable of similar engagement to even further assure stabilized capsule orientation.
