Current Splitter For LED Lighting System

A system for powering a light emitting diode (LED) system, comprising:

• a circuit configured to receive an input power and to provide an output current;
• a first switching element;
• a second switching element;
• one or more control devices configured to control the first switching element to control a first current and to control the second switching element to control a second current;
• an interface configured to receive a variable reference signal;
• wherein the one or more control devices are configured to control the first current and the second current according to a current ratio control curve independent of the output current based at least in part on the variable reference signal.

A method for controlling a light emitting diode (LED) lighting system, the method comprising:

• receiving an output current;
• providing a portion of the output current as a first current for a first LED array and a portion of the output current as a second current for a second LED array based at least in part on a variable reference signal;
• receiving an adjustment to the variable reference signal;
• and
• adjusting the first current and the second current independently of the output current according to a current ratio control curve, the current ratio control curve specifying the first current and the second current as a function of at least the variable reference signal.

A lighting system providing power to a plurality of light emitting diode (LED) devices, comprising:

• a circuit configured to provide a first current to a first LED array and a second current to a second LED array, the first LED array being associated with a different color temperature relative to the second LED array;
• a first interface configured to receive a variable reference signal;
• a second interface configured to receive a dimming control signal;
• wherein the circuit is configured to provide the first current and the second current as a function of at least the variable reference signal such that adjustment of the variable reference signal facilitates adjustment of a color temperature of an overall light output of the first LED array and the second LED array;
• wherein the circuit is configured to adjust a lumen output of the overall light output of the first LED array and the second LED array based at least in part on a dimming control signal.
