Abstract

The disclosure relates to a circuit for multi-color LED mixed color balance calibration, the circuit including: an LED loop including one or more LED channels with different colors, each of the one or more LED channels with different colors includes one or more LEDs with a same color and an LED switch; an LED junction configured to be connected to the one or more LED channels with different colors; a voltage divider resistor configured to be connected between the LED junction and a color calibration switch; the color calibration switch configured to enable or disable color calibration based on a received color calibration enable signal; and a microprocessor configured to: generate a color calibration enable signal, measure a first voltage, based on the generated color calibration enable signal, and adjust a mixed color output by the LED loop based on the measured first voltage.
