description Systems and methods for controlling a light emitting diode (LED) system having a plurality of LED arrays are provided. The lighting system can include a dimmable LED driver circuit configured to provide a driver output suitable for providing a driver current to the LED arrays. A current splitter circuit can be provided between the LED driver circuit and the plurality of LED arrays to control the ratio of current from the driver output provided to each of the plurality of LED arrays. The current splitter circuit can be configured to control the current ratio provided to the plurality of LED arrays independently of the driver output according to a current ratio control curve based at least in part on a variable reference signal provided at the current splitter circuit. Se proporcionan sistemas y métodos para el control de un sistema de diodo de emisión de luz (LED) que tiene una pluralidad de series LED. El sistema de iluminación puede incluir un circuito de excitación regulable LED configurado para proporcionar una salida de excitación adecuada para el suministro de una corriente de excitación a las series LED. Un circuito divisor de corriente puede proporcionarse entre el circuito de excitación LED y la pluralidad de series LED para controlar la razón de la corriente de la salida de excitación proporcionada a cada una de la pluralidad de series LED. El circuito divisor de corriente puede ser configurado para controlar la razón entre corrientes proporcionadas a la pluralidad de series LED de manera independiente de la salida de excitación de acuerdo con una curva de control de razón entre corrientes basado al menos en parte en una señal de referencia variable proporcionada en el circuito divisor de corriente.
