Title:
LIGHT-EMITTING DEVICE FOR A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/118613
Kind Code:
A1
Abstract:
The invention relates to a light-emitting device involving a converter which is intended for powering a pixelated light source controlled by electrical current. The proposed device makes it possible to reduce power losses and to reduce the risk of the elementary light sources of the pixelated light source overheating. By using a control loop and measuring means that make it possible to directly or indirectly measure a value indicative of the voltage drop at the terminals of at least one current source of the pixelated light source, it becomes possible to dynamically adapt the voltage supplied by the converter circuit.
