Abstract:
A lighting device includes a light source that emits an illumination light. The light source includes a first group of light emitting diodes (LEDs) to emit a first light, a second group of LEDs to emit a second light, and a third group of LEDs to emit a third light. The second light is warmer light than the first light, and the third light is cooler light than the first light. The lighting device further includes a first difference amplifier that controls a first current flow through the second group of LEDs at least based on a magnitude of a current flowing through the light source. The lighting device also includes a second difference amplifier that controls a second current flow through the third group of LEDs at least based on the magnitude of the current flowing through the light source.

Claim (Index 11):
A lighting device, comprising:\n a light source that emits an illumination light, the light source comprising a first group of light emitting diodes (LEDs) to emit a first light, a second group of LEDs to emit a second light, and a third group of LEDs to emit a third light, wherein the second light is warmer light than the first light and wherein the third light is cooler light than the first light; a first operational amplifier that regulates a flow of a first current through the second group of LEDs at least based on a first adjustable reference signal, a current flowing through the light source, and a first output signal generated by a first current sensor from the first current through the second group of LEDs, wherein the first output signal is independent of a first path current flowing through the first group of LEDs, wherein the current flowing through the light source includes a total of currents flowing through the first group of LEDs, the second group of LEDs, and the third group of LEDs; and a second operational amplifier that regulates a second current flow through the third group of LEDs at least based on a second adjustable reference signal, the current flowing through the light source, and a second output signal generated by a second current sensor from the second current flowing through the third group of LEDs, wherein the second output signal is independent of the first path current flowing through the first group of LEDs.
