Abstract:
1. An incandescent lamp comprising: a shell having an exterior side and an interior side defining a cavity, at least one internal wall formed in the shell defining a through passage extending from the exterior side to the interior side, and a mechanical coupling formed on the exterior side; the shell closed at a forward end by a lens; a light source located in the cavity facing the interior side, and coupled to electric lamp leads extending through the passage; a heat radiator assembly adjacent the exterior side, the radiator assembly having heat-dissipating surfaces exposed to air; wherein the heat radiator assembly includes a ring extending around the shell exterior, the ring positioned adjacent the lens, and the ring is supported by one or more arms extended from a mechanical attachment adjacent the through passage, the ring is offset from the exterior side by at least one passage, enabling airflow through the passage, between the ring and the exterior side, an integral power supply enclosed in the heat radiator assembly and electrically connected to the light source through the electric lamp leads; a threaded base having exterior electrical contact points electrically connected through base leads to the integral power supply; and the shell, radiator assembly and base being mechanically coupled as a unit.
