ANISOTROPIC INCANDESCENT LIGHT SOURCE

摘要

PROBLEM TO BE SOLVED: To provide an improved incandescent light source as may be used in a vehicle headlamp for providing forward illumination.

SOLUTION: The illuminating system includes a filament coil and an anisotropic reflector assembly. The filament coil is constructed from a coil of wire that is electrically conductive and has a high melting point and the primary axis of the coil of wire is substantially aligned with a principal axis of the reflector system. The light flux emitted by the filament coil toward the reflector system is rotationally anisotropic.
