Patent ID: 8545073

Claim:
A lighting module for motor vehicles comprising: a first concave reflector comprising at least a first focal point and a second focal point aligned on an optical axis of said first concave reflector, in such a manner that a majority of light rays leaving from said first focal point and reflected by said first concave reflector converge towards said second focal point; a second concave reflector and comprising at least a first focal point and a second focal point aligned on an optical axis of said second concave reflector, in such a manner that a majority of light rays leaving from said first focal point and reflected by said second concave reflector converge towards said second focal point, said first and said second concave reflectors having a truncated circumference in such a manner that a reflecting face of said first concave reflector is oriented towards that of said second concave reflector; a shield disposed within a plane between said first and said second concave reflectors, said shield having a first face facing said reflecting face of said first concave reflector and a second face facing a reflecting surface of said second concave reflector, said shield comprising a cut-off edge joining its first and its second face; and an optical element comprising a first focal point situated in a plane perpendicular to an optical axis of said lighting module and passing through said cut-off edge; said cut-off edge being situated at said second focal point of said first concave reflector and at said second focal point of said second concave reflector, and in that said first concave reflector of said lighting module comprises two intersecting reflection surfaces, each being a surface of revolution described by an ellipse in a half-plane having a first focal point and a second focal point aligned on an optical axis, said optical axes of said two intersecting reflection surfaces of revolution intersecting at said second focal point.
