Light transmitting system for automobile headlamp
First Claim
1. A light transmitting system for an automobile headlamp comprising a real light source, a light channel, means for concentrating flux from said source onto one end of said light channel, and a series of lenses, said light channel being formed by a single transparent bar arranged horizontally and transversely with reference to the direction of illumination, the front of said bar being formed by a vertical light output face and the rear of said bar having a series of vertical shape defining a series of oblique vertical reflecting facets constituting as many virtual light sources and being arranged in optical co-operation with said lenses, said lenses having axes which are parallel to the direction of illumination so that said lenses project images corresponding to said facets in said direction of illumination in order to form an assembly of elementary light beams merging into one single beam.

Abstract
A light transmitting system for an automobile headlamp having a real light source, means for a light channel and an elliptical reflector for concentrating the radiation from this source on the end of the light channel provided with a plurality of reflecting facets. The light channel is formed by a single transparent bar arranged horizontally and transversely with reference to the direction of illumination. The front of the bar is formed as a vertical light output face and the rear of the bar has a series of vertical steps defining a series of oblique vertical reflecting facets thus constituting as many virtual light sources. These facets are arranged in optical co-operation with lenses having axes parallel to the direction of illumination so that these lenses project images corresponding to the facets in the direction of illumination in order to form an assembly of elementary light beams merging into one single beam.
