Abstract: Systems and methods for controlling a light emitting diode (LED) system associated with an area and having a plurality of LED arrays are provided. In some implementations, the lighting system can include a first LED array associated with visible light and a second LED array associated with UV light. The lighting system can include one or more first sensors configured to detect occupancy within the area and send signals indicating whether the area is occupied. The lighting system can include one or more second sensors configured to detect microbes within an area and send signals indicating whether microbes are present in the area. The lighting system can include a control circuit configured to receive the signals sent by the one or more first and second sensors and to control the first LED array and the second LED array based on the signals.

Abstract: Systems and methods for controlling a light emitting diode (LED) system having a plurality of LED arrays are provided. The lighting system can include a dimmable LED driver circuit configured to provide a driver output suitable for providing a driver current to the LED arrays. A current splitter circuit can be provided between the LED driver circuit and the plurality of LED arrays to control the ratio of current from the driver output provided to each of the plurality of LED arrays. The current splitter circuit can be configured to control the current ratio provided to the plurality of LED arrays independently of the driver output according to a current ratio control curve based at least in part on a variable reference signal provided at the current splitter circuit.

Abstract: Lighting systems and methods implementing toggle control are provided. In one example implementation, a lighting system can include a first LED array having one or more LED devices and a second LED array having one or more LED devices. The system can further include a single throw circuit interrupter configured to receive power from a power source. The system can further include a power conversion circuit configured to convert an input power received via the toggle switch to a power output for the first LED array and the second LED array. The power conversion circuit can be configured to control a power distribution ratio between the first LED array and the second LED array based at least in part on a detected toggle input (e.g., a toggle pattern) implemented using the single throw circuit interrupter.
