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.
