Abstract
Systems and methods for operating one or more light emitting devices in a lighting array are disclosed. In one example, two or more negative temperature coefficient devices are electrically coupled in parallel so that a plurality of independently controlled lighting arrays may be controlled via a single amplifier. The two or more negative temperature coefficient devices are positioned in a negative feedback loop of the single amplifier.
