Abstract

Se proporcionan un sistema y un método para producir luz blanca en un dispositivo de iluminación de diodo emisor de luz (LED) ajustable. El sistema y método varía el "tiempo de apagado" de uno de los múltiples juegos de los diodos emisores de luz (LED) o de los canales en sucesión con el fin de compensar y estabilizar el desplazamiento de color o la degradación que ocurre en forma gradual en los LED. Cada canal corresponde a un color diferente. Al Variar el "tiempo de apagado" de un canal en un tiempo, el sistema utiliza, en forma eficiente la mayoría de los LED, lo cual permite la producción de una luz blanca más estable con menos LED.
