Rotating liquefied filament for high efficiency incandescent lamps

摘要

An incandescent light, which uses a rotating, liquefied filament. The rotating filament consists of a thin layer of filament metal deposited on the interior convex surface of a refractory filament mount, which is inside the torus. The filament device is designed to rotate at a speed sufficient to prevent the metal from boiling off from, or breaking away from, the refractory surface of the filament mount as it rotates. The rotational speed of the torus will create a centrifugal force greater than the thermal forces, which would otherwise destroy the molecular integrity of the filament metal. The temperature of the deposited filament metal will exceed its normal melting point as it rotates. As it becomes hotter it will luminesce more in exponential proportion to the current applied to the rotating torus filament assembly.
