US 10,764,548 B2 · Luminous device using a high-resolution light source

Abstract

A luminous device for a motor vehicle, said device including a pixelized light source and an optical system that is arranged to project a pixelized light beam emitted by the pixelized light source, the optical system comprising a first mirror arranged to collect and reflect rays of the pixelized light beam emitted by the pixelized light source, a second mirror arranged to reflect the rays reflected by the first mirror, and a third mirror arranged to receive the rays reflected by the second mirror and to reflect these received rays so as to correct field aberrations. The invention enables improved projection of a pixelized light beam by a luminous motor-vehicle device.

Dependent claims

A luminous land-vehicle device for illuminating a scene, comprising:

a monolithic electroluminescent source comprising electroluminescent elements;
an optical system arranged to form an image of the monolithic electroluminescent source;
and
an electronic device configured to
receive at least one first measurement regarding at least one physical parameter of a vehicle, the luminous land-vehicle device being integrated with the vehicle,
receive at least one second measurement regarding at least one physical parameter of the scene, and
control illumination of the electroluminescent elements of the monolithic electroluminescent source depending on the received at least one first measurement and the received at least one second measurement,
wherein a refresh frequency of the at least one first measurement is higher than a refresh frequency of the at least one second measurement.

5 more elements

A method for illuminating a scene with a luminous land-vehicle device, comprising:

receiving, by an electronic device, a first measurement of at least one physical parameter of a vehicle, the luminous land-vehicle device being integrated with the vehicle;
determining, by the electronic device and based on the received first measurement, which electroluminescent elements of a monolithic electroluminescent source must be turned on;
and
configuring, by the electronic device, at least the determined electroluminescent elements of the monolithic electroluminescent source so that they emit light.
