Abstract: Methods and systems are provided for operating a lighting array that is comprised of one or more lighting segments. In one example, the lighting segments may be comprised of light emitting diodes that are electrically coupled in series. The lighting segments may be controlled responsive to output of a potentiometer and the lighting segments may be controlled responsive to positions of circuit boards in an enclosure.

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.

Abstract: A system and method for operating one or more light emitting devices is disclosed. In one example, a reference voltage input at an error amplifier receiving a feedback signal from the one or more light emitting devices is adjusted to a first higher voltage independent of a requested irradiance of the one or more light emitting devices during startup in order to accelerate startup of a switching regulator driving the one or more light emitting devices. Subsequently, upon an output of the switching regulator reaching a desired voltage, the reference voltage is adjusted based on the desired irradiance of the one or more light emitting devices.

Abstract: A system and method for operating one or more light emitting devices is disclosed. In one example, an analog circuit outputs a voltage pulse to drive a voltage regulator in a way that may provide more consistent light intensity from the one or more light emitting devices over a range of requested lighting intensity levels.

Abstract: A system and method for operating one or more light emitting devices is disclosed. In one example, the switching of a regulator is ceased in response to a request to stop supplying power to one or more light emitting devices. The approach may reduce power consumption of a lighting system when light is not requested.
