    Patent number: 10337686
    Abstract: A headlight for a vehicle with a projector includes a reflector, a light source, a diaphragm, and a collimating optical element. The reflector includes a bowl-shaped reflective surface, which presents the shape of a concave curve in a cross-section formed by a vertical plane passing through the optical axis of the projector. The light source is positioned substantially at the source focal point of the curve. The diaphragm is positioned substantially at the image focal point of the curve to create a light-darkness boundary in front of the vehicle. The optical element is for collimation of the output light beam into the required direction. The diaphragm is made of a transparent material and includes one or more optical surfaces arranged to direct those rays that have fallen onto it and passed through it to the collimating element directly, or through a supplementary optical element.
