Abstract:
A vehicle headlamp includes a housing closed by a transparent outer lens and, inside the housing, a lighting module that emits a light beam in the direction of an optical axis defining a cone of light and a transparent screen that is positioned between the lighting module and the outer lens and receives, in its thickness, a light beam emitted by a light source. An internal face of the screen is provided with optical modules that reflect the light emitted by the light source in the direction of the outer lens. The outer lens forms a first angle of 60 to 100° with the optical axis of the lighting module and the screen forms a second angle such that a part of the cone of light of the light beam that is situated beneath the optical axis is reflected by the screen above the lighting module.
