    • 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.
    • 提供了用于平衡LED电路中的电压的系统和方法。 LED电路可以具有彼此并联耦合的多个LED串。 每个LED串可以包括串联耦合的多个LED器件。 LED串可以从驱动器电路接收驱动电流。 根据本公开的示例实施例,多个LED串中的至少一个可以包括与LED串串联耦合的恒定电流调节器电路。 恒流调节器电路可以提供通过LED串的恒定电流。 驱动器电流的平衡或余数可以提供给另一个LED串。 恒流调节器电路可以提供多个并联LED串之间的电压平衡。
