Lighting and/or signaling unit, notably for a motor vehicle

摘要

A lighting and/or signaling unit comprising a pair of light sources both cooperating with an optical element in such a way as to form two output light beams, depending on the desired lighting function. The output diopter, notably formed by elliptical portions, is adapted to accommodate the generation of beams from two sources spaced apart.;Applicable to the motor vehicle industry.

主权项

1. A lighting and/or signaling unit, notably for a motor vehicle, comprising a first light source and an optical element comprising an input diopter and an output diopter, said optical element being configured to enable an emission of a first output light beam by said output diopter on reception of a first input light flux, generated by said first light source, by said input diopter, said optical element being configured to enable an emission of a second output light beam by said output diopter on reception of a second input light flux, generated by a second light source, by said input diopter, said output diopter comprising a first portion matched more particularly to said first light source and a second portion matched more particularly to said second light source;
wherein said first light source has a first mean emission direction and said second light source has a second mean emission direction, said first and second mean emission directions being generally parallel to an optical axis of said optical element and being spaced apart from one another in a direction at generally right angles to their respective first or second mean emission directions; wherein said first mean emission direction of said first light source goes through said first portion of said output diopter and said second mean emission direction of said second light source goes through said second portion of the output diopter; said first portion and second portion being generally elliptical and having a first focus and a second focus, respectively, said first and second light sources being generally situated at said first and second focuses, respectively; wherein said optical diopter is substantially symmetrical about an intersection between said first portion and said second portion.
