Abstract: Systems and methods for balancing voltage in LED circuits are provided. An LED circuit can have a plurality of LED strings coupled in parallel with one another. Each LED string can include a plurality of LED devices coupled in series. The LED strings can receive a driver current from a driver circuit. According to example embodiments of the present disclosure, at least one of the plurality of LED strings can include a constant current regulator circuit coupled in series with the LED string. The constant current regulator circuit can provide a constant current through the LED string. The balance or remainder of the driver current can be provided to the other LED string. The constant current regulator circuit can provide for voltage balancing among the plurality of parallel LED strings.

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.

Abstract: A method of controlling a correlated color temperature for light output by a lighting device including a dim-to-warm circuit having a first light channel and a second light channel. The method including receiving a current input; measuring current of the current input to obtain a measured current value; and determining a light control value based on the measured current value. The method further including using the light control value, determining a first current value for applying a first current to the first light channel and determining a second current value for applying a second current to the second light channel; and providing the first current to the first light channel and providing the second current to the second light channel to obtain different desired correlated color temperatures for the light output at different ones of the light control values.
