Patent ID: 7977855

Claim:
An incandescent illumination system for projecting a beam of light, comprising: a concave reflector configured to be substantially symmetrical about a longitudinal axis; and an incandescent lamp including a coiled coil filament wherein the larger coils of the coiled coil filament are wound to provide a spacing between adjacent coiled coils selected to be a distance the same as the filament coil diameter and arranged with a longitudinal axis of said filament oriented substantially perpendicular to the longitudinal axis of said concave reflector; said spacing between adjacent coils reducing blocking or absorption of light radiation emanating from an interior of said coiled coil filament and providing a solid wave front of light aligned with a center of the filament and appearing to emanate from a center focal point of the concave reflector; wherein a substantial portion of the light emitted by the lamp impinges on, and is redirected by, the reflector to project a high intensity beam of light.
