Abstract
An improved incandescent lamp is disclosed that is specially adapted for use in combination with a concave reflector in providing a high-intensity beam of light. The lamp includes a plurality of linear, helically-wound filaments arranged with their longitudinal axes parallel with each other and spaced substantially uniformly around the lamp's central longitudinal axis. Orienting such a lamp with its longitudinal axis aligned with the reflector's longitudinal axis, and with the filaments near the reflector's general focal point, ensures that a high proportion of the emitted light is collected by the reflector to project the high-intensity beam.
