Classification: CPC F  H | IPC F  H

Claim 0:
1. An illumination system of an imaging unit comprising:
an illumination unit that includes one or more light emitting diodes (LEDs) and a memory storing data indicative of the LEDs;
an LED driver;
a temperature sensor; and
a voltage controller comprising:
a power input operatively connected to a power supply;
an input port configured to receive a control signal for setting an output voltage;
a voltage output port, wherein the voltage controller is configured to convert a voltage sensed at the power input port to an output voltage supplied to the voltage output port; and

at least one processor operatively connected to the temperature sensor, the illumination unit, and the voltage controller, the at least one processor being configured to:
obtain the data stored at the memory of the illumination unit;
obtain a temperature value from the temperature sensor;
analyze the obtained data and the temperature value to determine a minimum voltage to operate the LEDs in accordance with an illumination cycle; and
send a control signal to the input port of the voltage controller to set the output voltage of the voltage controller to the minimum voltage.
