1. A headlamp projecting at least one illumination beam pattern, comprising:
- a first array of illumination light sources, the light sources arranged within the first array in a pattern which substantially corresponds to the pattern of illumination which is desired to be produced by the headlamp; and
a first converging lens having a substantially uniform spread, the uniform spread being larger in the horizontal direction than the vertical, the first lens receiving light produced by the first array of illumination sources and projecting the received light to form the at least one illumination beam pattern.

Abstract
A headlamp comprising at least one array of illumination light sources, the light sources positioned substantially corresponding to a desired illumination beam pattern for the headlight, the light from the light source of the array being provided to a lens which projects the light in the illumination beam pattern. Preferably, the light is provided from LED light sources which are coupled to fiber optic cables to form the array of illumination source. Also preferably, the light sources can be illuminated in different patterns, to provide different illumination beam patterns.

12. A headlamp employing a plurality of LED light sources as illumination sources, each respective LED light source being optically coupled to one end of a respective fiber optic cable, the other end of each fiber optic cable being arranged in an array having the general shape of a desired pattern of illumination to be output from the headlamp, the headlamp further including a lens to receive the light emitted from the ends of the fiber optic cables and to project that light into the desired illumination beam pattern.
