Abstract
A lighting module for a motor vehicle headlight intended to produce a low beam having an at least partly oblique cut-off. This same module further comprises an additional lighting function making it possible to generate a high type beam, the dimensions of the lighting module remaining identical. The light sources of the two respective low and high beam functions are arranged in a vicinity of the focus of an optical portion of the module such that the lighting module remains compact.
Claims20
A lighting module for a motor vehicle, comprising:
- an optical element to produce at least one first beam exhibiting an at least partly oblique cut-off, the optical element comprising at least one first optical portion having an optical axis and a focus,
- at least one first light source, the at least one first light source being arranged at the focus for emitting first light rays toward the optical element to produce the at least one first beam, and
- a second light source, the second light source being arranged at a distance from the focus, and not overlapping the focus, and offset downward relative to the at least one first light source on a vertical axis, the second light source emitting second light rays toward the optical element to produce a second beam at least partially lighting above the at least partly oblique cut-off, an optical beam formed by overlapping of the first beam with the second beam exhibiting no cut-off.
