Abstract[English]
This system (1) for controlling the supply of power to light-emitting diodes (3) comprises a first set (5) of light-emitting diodes (3) and a second set (7) of light-emitting diodes (3) and also a management unit (11) comprising a microcontroller (13) connected to a central computer (17), a power converter (15) for the sets (5; 7) of light-emitting diodes (3), connected to the microcontroller (13) by a communication bus (19), the system (1) comprising a power supply module (23) for the power converter (15) and the microcontroller (13) and also a switch (21) driven by the microcontroller (13) between a first and a second position in which power is supplied to the first and second set (5; 7) of light-emitting diodes (3), respectively, by the power converter (15).[French]
Ce système (1) de pilotage de l'alimentation de diodes électroluminescentes (3) comprend un premier ensemble (5) de diodes électroluminescentes (3) et un deuxième ensemble (7) de diodes électroluminescentes (3) ainsi qu'une unité de gestion (11) comprenant un microcontrôleur (13) relié à un calculateur central (17), un convertisseur de puissance (15) des ensembles (5; 7) de diodes électroluminescentes (3) relié au microcontrôleur (13) par un bus de communication (19), le système (1) comprenant un module d'alimentation (23) du convertisseur de puissance (15) et du microcontrôleur (13) ainsi qu'un interrupteur (21) piloté par le microcontrôleur (13) entre une première et une deuxième positions d'alimentation respectivement du premier et du deuxième ensemble (5; 7) de diodes électroluminescentes (3) par le convertisseur de puissance (15).
