Method of providing modulated illumination of a road, and a vehicle headlight for performing the said method
First Claim
1. A method of lighting a road scene with a vehicle headlight comprising:
- detecting in a road scene at least one living being;
pinpointing dimensions and location of the at least one living being detected in the road scene;
creating, on an imager, at least one mask having dimensions and a position corresponding to the dimensions and location of the at least one living being detected in the road scene;
illuminating the road scene through the imager; and
projecting at least one shadow around the at least one living being when the at least one living being is detected in the road scene.

Abstract
The invention relates to a method of lighting a road with a vehicle headlight, in which the projected light is modulated in response to the presence of any persons on the road. The method comprises the following operations: detecting in the road scene at least one person, pinpointing the location of the person in the road scene, creating on an imager a mask having dimensions and position corresponding to the person, and lighting the road through the imager, to create a projected shadow around the person.
The invention also provides a headlight for performing this method and having a first light source towards the imager, and an electronic system for generating light-occulting masks on the imager.

11. A main beam headlight for a vehicle comprising:
-
a first light source and a system for modulating light emitted by said first light source, wherein said system for modulating comprises; at least one light guide for transporting light emitted by said first light source to an imager, said at least one light guide having a cross section and comprising at least one matrix of optical fibers or an optical fiber having said cross section; and an electronic system comprising a means for detecting a road scene and a means for generating masks on said imager to block passage of light transported by said at least one light guide through said imager in response to a detected image of a road scene. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
